You buy fuel, pay the federal excise tax at the pump or rack, and then put that fuel to a qualifying nontaxable use such as off-highway business use, farming, or export. Schedule 1 of Form 8849 is how the ultimate purchaser claims that tax back as a refund.

Two rules gate the claim before any gallons matter. Each filing has to total at least $750, and only one Schedule 1 may be filed per quarter, during the first quarter following the last quarter on the form. After acceptance, an e-filed claim typically pays in about 45 days, and the refundable rate runs 18.3 cents per gallon on most gasoline and 24.3 cents on diesel.

Key Takeaways

• You use Form 8849, Schedule 1 when you are the ultimate purchaser and your fuel was used for a qualifying nontaxable purpose, for example off‑highway business use, farming, certain government or nonprofit use, or exports.
• Claims must generally meet a minimum of 750 and be filed once per quarter, during the first quarter after the last quarter included. If you cannot meet the threshold or timing, annual procedures apply.
• Covered fuels include gasoline, aviation gasoline, undyed diesel, undyed kerosene, aviation kerosene, LPG, CNG, and certain exported dyed fuels or blendstocks, each with specific line items and rates.
• E‑file is available and optional. After IRS acceptance, Schedule 1 refunds typically process in about 45 days. Paper is allowed, but it is slower.
• For exports, keep and link proof of export to the exact gallons, such as a bill of lading or foreign consignee statement.
• Rate details matter. For most nontaxable gasoline claims the refundable portion equals 18.3 cents per gallon, for diesel 24.3 cents, and aviation gasoline often 19.3 cents, with special reduced rates for certain buses. The separate 0.1 cent LUST tax is generally not refundable, with one important exception: aviation fuels used in foreign trade can recover the $0.001 LUST tax on line 2d (aviation gasoline) and line 5e (kerosene), filed in addition to the regular refund on lines 2b or 5c/5d. Always verify the current schedule and instructions.

What is Form 8849 Schedule 1

Form 8849 is the IRS platform for excise tax refunds. Schedule 1 is the attachment used by the ultimate purchaser to claim back the federal excise tax on fuel that was later used in a qualifying nontaxable way. You report gallons, the matching type‑of‑use code, and the applicable per‑gallon rate to compute the refund.

In plain terms, if you paid the highway rate at purchase but the fuel did not power a taxable highway use, you may be eligible to recover the federal tax. That includes off‑highway business use, farm use, certain government or nonprofit uses, some aviation uses, and exports with proper proof.

Who can claim and when

You must be the ultimate purchaser of the fuel, which means you bought it and used it. Exporters are treated as ultimate purchasers for exported fuel. Your quarterly Schedule 1 claim must reach at least 750, and you file it in the first quarter after the last quarter included. Only one claim per quarter is allowed. If you do not meet the threshold or miss the window, use the annual claim rules in the 8849 instructions.

Calendar example that works: you used fuel in July through December. File one combined claim between January 1 and March 31. If you already claimed part of that period, you cannot re‑claim those quarters in the combined filing.

Covered fuels and where people slip

Schedule 1 covers gasoline, aviation gasoline, undyed diesel, undyed kerosene, aviation kerosene, LPG, CNG, and certain exported dyed fuels or gasoline blendstocks. The mistake I see most often is mixing dyed and undyed diesel. Lines for undyed fuel require a certification that there is no visible dye – and if any fuel in the claim does show visible dye, do not skip the claim outright; the form provides an exception path that requires you to attach a detailed explanation and check the exception box on line 3 or line 4. Dyed fuel shows up mainly in the export section, which requires proof of export.

Match your use to the right code

Every gallon must tie to an allowed Type‑of‑Use. Examples include off‑highway business use, farming, qualified bus categories, government, and nonprofit educational uses. The IRS provides a Type‑of‑Use table and line‑by‑line instructions. If you are claiming aviation uses, separate commercial from noncommercial. If you are claiming exports, include the export proof in your records.

• Off‑highway business use is common for construction equipment and generators (Type of Use 2 covers business use only – personal off-highway use and use in a motorboat are excluded).
• Government and nonprofit educational uses require that the entity is eligible and that the fuel was used exclusively in qualifying activities.
• Bus use has special reduced rates. Make sure your routes and passenger definitions fit the rule before you assume the lower rate, and remember the form requires you to write "Bus" in the space to the left of column (a) and manually enter the reduced credit rate in column (b) – the pre-printed rate is for the non-bus case, so the lower rate does not apply automatically.

A quick note on what changed for 2025

Two items to know as you prepare 2025 filings. First, the IRS confirms the ongoing availability of e‑file for Form 8849 and maintains technical updates for the Modernized e‑File program. That is good news for faster timing and cleaner validations. Second, alternative fuel and biodiesel mixture credits that many teams used on Schedule 3 were noted in the March 2025 Pub. 510 update as expired after 2024 unless Congress extends them. If you are adjusting processes, keep Schedule 1 and Schedule 3 logic separate.

Tip, keep a one‑page “rates and codes” cheat sheet inside your monthly close binder and refresh it each January when the IRS updates sites and publications. That single habit prevents most rework.

In the next section, you will see how to translate these rules into a clean, repeatable workflow that your team can run each quarter, with examples and a table you can copy into your SOP.

Build a repeatable Schedule 1 workflow your team can run every quarter

You do not need a giant software project to get Schedule 1 right. You need a tight checklist, clear owners, and records that match your gallons to a valid type‑of‑use. Here is the simple workflow I teach new staff during quarter close. It reduces rework and gets refunds in the door faster.

The 7 step workflow

1. Capture the data

• Pull fuel purchase details by period. Export pump or card statements, tank withdrawals, and any bulk delivery receipts.
• Normalize units and confirm that gallons and dates align to the quarter you plan to claim.

2. Classify the use

• For each fuel batch, choose a valid Type‑of‑Use from the IRS table. Separate aviation, off‑highway business, farm, government, nonprofit educational, and bus uses.
• Mark dyed versus undyed for diesel and kerosene. If undyed, you will certify that there is no visible dye.

3. Tie documentation to each line

• Attach invoices, usage logs, equipment lists, route logs for bus claims, and export proof for any exported gallons.
• For exports, keep the bill of lading, any export declaration, and a foreign consignee statement in the same folder as the gallons you are claiming.

4. Calculate the claim

• Multiply gallons by the applicable per gallon rate for the period and use code.
• Sum by line so your totals match your e‑file inputs.

5. Internal review

• Have a second preparer verify gallons, dates, and codes.
• Reviewer checks that every undyed diesel and kerosene line includes the no visible dye certification and that export proof is present.

6. File and track

• E‑file through an IRS approved provider when possible. E‑file validation catches many data issues before the IRS sees them.
• Record the submission ID and expected refund window on your calendar.

7. Reconcile and retain

• Reconcile claimed gallons to your inventory or purchase totals to prevent duplicates in a later quarter.
• Keep a clean folder for each claim period so a future review is painless.

What data you need and where to find it

Data you need	Where it usually lives	Why it matters
Gallons by fuel type and date	Card statements, vendor invoices, bulk tank logs	Core of the refund calculation
Type‑of‑Use mapping	Equipment list, job codes, cost center logs	Proves the fuel was used in a qualifying way
Dyed status and certifications	Vendor product specs, purchase notes	Required certifications for undyed lines
Export proof	Bills of lading, export declarations, consignee statements	Mandatory for export lines
Entity details	Legal name, EIN, addresses	Must match Form 8849 header
Quarter close dates	Close calendar, controller checklist	Ensures one claim per quarter with the 750 minimum met

Who owns each step inside your firm

Step	Owner	Backup	QC checkpoint
Data pull and normalization	Staff accountant	AP specialist	Spot check totals to vendor statements
Use classification	Operations or tax staff	Controller	Reviewer tests a sample against logs
Documentation tie out	Staff accountant	Ops coordinator	Reviewer confirms export packets are complete
Calculations	Staff or senior	Senior	Reviewer recomputes one line per fuel type
Filing	Senior or manager	Controller	Submission ID recorded and verified
Retention	Controller	Doc admin	Folder is complete and read only

If you run a seasonal operation, assign a temporary “Schedule 1 captain” from July to March. Give them a clear playbook and five hours a month. That small commitment eliminates most rush filings later.

A working example you can copy

• July through September, your team bought 12,400 gallons of undyed diesel for off‑highway equipment and 1,200 gallons of gasoline for generators on job sites.
• You also exported 3,600 gallons of dyed diesel in August.
• You tag the diesel as off‑highway business use, certify no visible dye, and attach vendor invoices and equipment logs.
• For gasoline, you mark off‑highway business use and attach site generator logs.
• For exports, you attach the bill of lading and consignee statement.
• You compute each line using the per gallon rates for that quarter, sum the totals, confirm the combined claim exceeds 750, and schedule the filing during the first quarter after September.

Timing tips that protect cash flow

• Work backward from your quarterly close. If you close by the 15th after quarter end, you can finish Schedule 1 prep that same week.
• E‑file as soon as your books are closed for the period. Faster acceptance means faster refunds.
• If you run close to the 750 minimum, avoid slicing quarters too thin. Combine quarters that have not yet been claimed so you qualify and stay compliant with the one claim per quarter rule.

What to put on each line, a plain English map

You do not need to memorize line numbers. You do need to understand what belongs on each section so your workpapers mirror the form your e‑file provider generates.

The quick reference table for line choices

Fuel category	Common qualifying uses	Key notes	Typical attachments
Gasoline	Off‑highway business, farming, certain nonprofit educational, some exports	Use correct type‑of‑use codes, do not mix with aviation gasoline	Invoices, equipment logs, export proof if exported
Aviation gasoline	Commercial, noncommercial, exports	Separate commercial from noncommercial, rates differ	Flight logs, airport fuel tickets, export proof for exports
Undyed diesel fuel	Off‑highway business, farming, certain bus uses, certain government or nonprofit educational uses	Certify no visible dye, separate bus uses due to special rates	Invoices, equipment or route logs, bus route documentation
Undyed kerosene	Space heating, certain off‑highway equipment, aviation kerosene when appropriate	Certify no visible dye, separate aviation kerosene lines	Invoices, usage logs, certifications
LPG and CNG	Qualified off‑highway and other allowed uses	Track gallon equivalents consistently	Supplier statements and meter logs
Diesel–water emulsions	Approved uses per instructions	Rare, keep manufacturer detail with invoices	Product spec and invoices
Exported dyed fuels and blendstocks	Fuel physically exported outside the U.S.	Keep export proof, do not claim without documents	Bill of lading, consignee statement, export declaration

Golden rule, map each gallon to one allowed use and one line, then stop. Duplicate gallons across lines or across quarters is the fastest way to lose a refund.

How to file, e‑file or paper, without missing a step

When you know your gallons, uses, and documents are clean, filing should feel routine. Your options are e‑file through an IRS approved provider or mail a signed paper return. The information you provide is the same in either path. The difference is speed and error checks.

E‑file steps that keep things moving

• Set up your account with an IRS approved e‑file provider that supports Form 8849 with Schedule 1.
• Enter your legal name and EIN exactly as it appears on IRS records.
• Select the claim period and build each line by fuel type, item number, type‑of‑use code, gallons, and the correct rate for that period.
• Upload attachments for exports and any dye certifications your provider allows.
• Validate before you submit. E‑file software often catches missing codes or totals that do not foot.
• Save the submission receipt and any acknowledgment files in the same folder as your workpapers.

Paper filing that will not slow you down

• Complete Form 8849, attach Schedule 1, sign, and include your support packet.
• Print export proof and any certifications. Put a simple index on top so IRS reviewers can follow your logic.
• Mail to the address in the current instructions and keep a copy of everything you send.
• Track the postmark date and set a reminder to follow up if you do not see movement in a reasonable window.

Attachments that matter most

• For exports, include the bill of lading, export declaration if available, and a foreign consignee statement. The names, gallons, and dates should match your line entries.
• For undyed diesel and kerosene, include your no visible dye certification in the workpapers and reference it in your line notes.
• For bus uses, include route descriptions and ridership detail that shows you qualify for the bus category and any special rate.

Simple rule, every gallon on a line should have a paper trail you can hand to a reviewer who knows nothing about your business and still make sense.

Quality control checklist before you submit

• Names, addresses, and EIN match IRS records
• One claim for the quarter, and the combined total is at least 750
• Gallons tie to invoices, logs, or meter readings
• Type‑of‑use code is valid for the fuel type
• Export packets are complete and indexed
• Undyed certifications included for diesel and kerosene lines
• Summaries and subtotals foot to the return
• Submission receipt saved to the claim folder

Prevent the mistakes that cause delays

Small slips cause the biggest headaches. Here is a quick red‑to‑green list you can keep on your wall.

• Mixing dyed and undyed diesel on the wrong lines. Fix by reviewing product specs and certifying dye status for undyed lines.
• Filing too soon or too often. Fix by waiting until the first quarter after your latest included quarter and limiting to one claim per quarter.
• Missing export proof. Fix by collecting the bill of lading and consignee statement before you book the revenue from the refund.
• Duplicating gallons across periods. Fix by reconciling claimed gallons to purchases and inventory movements.
• Using the wrong type‑of‑use code for aviation or bus categories. Fix by having a reviewer confirm eligibility and rates before you finalize.

Where a structured delivery partner helps

If your in‑house team is buried in busy season work, a disciplined offshore delivery model can keep Schedule 1 moving without pulling partners into review loops. With standardized workpapers, a multi‑layer review, and predictable SLAs, you get clean claims each quarter while your senior staff focus on advisory work. That is the kind of operational lift we value. On Accountably.com, we talk about building capacity with structure, not just adding people, so your filings stay on time and audit ready.

Turn rules into a living SOP

Writing a one page policy is nice. Running the same clean process every quarter is what gets refunds in your bank account. Your SOP should tell staff exactly where to find data, how to classify uses, what to attach, and who signs off.

Your Schedule 1 SOP outline

• Purpose and scope, who this covers and which fuels are in play
• Data sources and owners, card statements, bulk tank logs, export docs
• Type‑of‑use mapping rules with examples for your exact operations
• Calculations, rates, and period controls with a simple calculator sheet
• Review path, preparer to senior to quality to final approver
• Filing method, e‑file settings or paper address and signature rules
• Retention and audit readiness, folder structure and naming standards
• Calendar and SLAs, due dates, reminders, and what to do if something slips

Sample folder tree you can copy

Folder	Contents	Owner
00 Cover and checklist	Claim index, QC checklist, signatures	Controller
10 Purchases and gallons	Invoices, card exports, bulk logs	Staff accountant
20 Use mapping	Equipment list, routes, project codes	Operations lead
30 Calculations	Rate sheet, calculator, tie‑outs	Senior
40 Export packets	Bills of lading, consignee statements	Ops coordinator
50 Certifications	No visible dye certifications, bus eligibility	Senior
60 Return and submission	PDF of Form 8849 and Schedule 1, e‑file receipts	Controller

Keep each quarter’s claim in its own folder. If you aggregate quarters in one filing, sub‑folders keep source documents separated so you will not double count.

Line by line, how to choose the right category and compute your claim

A clean claim starts with the right line. Think fuel first, then use, then rate. If you do that in order, the calculation is usually straightforward.

Gasoline and aviation gasoline

• Gasoline used off highway or for farming goes on the gasoline lines with the proper type‑of‑use code. Separate any export gallons and keep those documents together.
• Aviation gasoline requires you to split commercial from noncommercial. Keep flight logs handy. Exports live on the aviation gasoline export line.
• For each line, gallons multiplied by the period rate equals the refundable amount. Watch for special reduced rates for certain buses and do not apply them unless you qualify.

Practical tip, tag aviation transactions in your accounting system with a short class code, for example AV‑COMM or AV‑NONCOMM. This helps prevent cross‑contamination with regular gasoline claims at quarter end.

Undyed diesel and undyed kerosene

• These are the workhorses of most claims. You must certify that there is no visible dye when you claim on undyed lines.
• Off‑highway business use and farming are the most common use codes. Government and nonprofit educational uses are possible, but only when the entity and activity truly qualify.
• Some bus categories have lower rates, so verify eligibility. If you run mixed routes, keep ridership details that show which trips qualify.

If you store both dyed and undyed fuel on site, label your bulk tanks and keep meter logs. The biggest review time sink is proving which pump or tank dispensed which product.

Aviation kerosene, LPG, CNG, diesel–water emulsions

• Aviation kerosene can look similar to undyed kerosene in your books, so keep the product type on the invoice and in your mapping sheet.
• LPG and CNG are eligible in specific non‑taxable uses. Track gallon equivalents consistently – LPG is filed in GGE (5.75 lb or 1.353 gal per GGE), CNG in GGE (5.66 lb or 123.57 cu ft per GGE), and LNG in DGE (6.06 lb or 1.71 gal per DGE); raw gallons will give the wrong refund – and keep supplier statements in the period folder.
• Diesel–water emulsions are rare. If you claim them, keep the product specification, invoices, and any manufacturer statement with your workpapers.

Exports and gasoline blendstocks

For export claims, tie every gallon to proof that the fuel left the United States. Your core packet usually includes a bill of lading, an export declaration or carrier record, and a foreign consignee statement. Match dates and quantities to your line entries.

If the export proof and your gallons do not reconcile, stop and fix it before you file. Export lines get extra attention and incomplete packets are the top reason for delays.

Mini calculator you can drop into your SOP

• Step 1, enter gallons by fuel and use code in column A.
• Step 2, enter the per‑gallon rate for that fuel and use in column B.
• Step 3, compute refund by line, A × B.
• Step 4, sum all lines. Confirm the total meets or exceeds 750.
• Step 5, confirm one quarter per claim. If you need to aggregate, only include quarters not already claimed.

Keep this on a shared sheet with locked formulas and a change log. That single control reduces math errors and speeds review.

Documentation, what to keep and how to store it

Your goal is simple, make it easy for a reviewer to follow the money, the gallons, and the use – and remember the caution at the top of the form: your records must include the seller's name and address and the dates of purchase, not just receipts.

Core documents by claim type

Claim type	Must have	Nice to have
Off‑highway business	Vendor invoices, meter or usage logs, equipment list	Photos or serial numbers of large equipment, site logs
Farming	Fuel invoices, farm activity logs	Field maps or job codes showing seasonality
Government and nonprofit educational	Eligibility proof, usage logs	Board resolutions or contracts showing mission fit
Bus categories	Route descriptions, timetables, ridership summaries	Maps with mileage splits for qualifying vs nonqualifying service
Aviation	Fuel tickets, flight logs, aircraft identifiers	Maintenance records confirming aircraft type
Exports	Bill of lading, export declaration, consignee statement	Carrier confirmations, customs entries

Retention timeline and version control

• Keep each quarter’s claim packet intact for your records. A five year retention policy is common for excise records.
• Use standardized names so files sort correctly, for example 2025‑Q3 8849 S1 40 Export Packet.
• Convert emailed proofs to PDF and store them in the claim folder, not in personal inboxes.
• Use read only folders for finalized claims. Add a short change log if you must correct a filing later.

Internal quality layers that save partner time

• Preparer checks numbers and attachments.
• Senior verifies type‑of‑use and rate selections.
• Quality reviewer confirms certifications and export proof, and signs the checklist.
• Final approver submits and stores the receipt.

If you have seasonal spikes, consider designating a floating reviewer who only checks export and aviation lines. Concentrating that expertise lowers your error rate where it matters most.

Security, compliance, and work integrity in practice

You are handling taxpayer IDs, invoices, and sometimes customs documents. Treat this like client tax data.

• Limit access to claim folders to staff who work the file.
• Use role based permissions and secure file exchange for any third party documents.
• Keep audit logs and avoid local storage on personal devices.
• Document who certified undyed status and when.

If you partner with an external delivery team, ask for SOC 2 aligned controls, NDA backed confidentiality, and a zero local storage policy. Structured safeguards are non negotiable when you handle excise claims and export packets.

Related schedules and how they interact with Schedule 1

• Schedule 2 is for registered ultimate vendors. If you are the end user and not a registered ultimate vendor, that is not your path.
• Schedule 3 covers biodiesel or renewable diesel mixtures, alternative fuel, and certain sustainable aviation fuel rules. Keep it separate from Schedule 1 so you do not double count gallons.
• Schedule 5 deals with section 4081 tax previously reported on Form 720.
• Schedule 6 is a catchall for other excise claims.
• Schedule 8 is for credit card issuers.

When in doubt, check whether you are the ultimate purchaser and whether the fuel use is nontaxable. If yes, you are usually in Schedule 1 territory. And remember the form's own instruction: attach Schedule 1 to Form 8849 and do not file it with any other schedule – if you also need to file Schedule 2 or Schedule 3, prepare separate Form 8849 submissions for each.

Real world examples that mirror common use cases

• A construction firm runs generators and compressors on job sites. All gallons that power those units are off‑highway business use. Keep equipment logs and site addresses tied to each invoice.
• A university operates campus shuttles that qualify under a bus category. Keep route maps and ridership data to confirm the category and rate.
• A distributor exports dyed diesel to a customer in Latin America. Keep the export packet together and map gallons to the exact shipment dates you claim.

Each of these can be filed cleanly if you stick to the workflow, keep the packet complete, and file on a predictable schedule.

How Accountably can support your team, without adding noise

If your team is underwater during peak season, the right offshore operating model can keep Schedule 1 current, accurate, and audit ready. Our approach at Accountably is to embed trained offshore staff into your workflow with clear SOPs, standardized workpapers, and layered reviews, so partners stay out of the review loop and clients get timely refunds. We work in your systems, follow your templates, and keep a predictable cadence with defined SLAs and continuity plans. Mention us when structure, not resumes, is the missing piece.

Compliance, E‑E‑A‑T, and a quick disclaimer

This article is written to help you apply the rules in real operations. Always confirm the current year’s instructions and rates before you file, and document your decisions in your workpapers. If your facts are unusual, talk with your tax advisor. Nothing here is legal or tax advice for your specific situation.

Trust is built with good records. If a stranger can open your quarterly folder and understand your story, you are ready for a smooth refund.

Conclusion, turn a messy pile of invoices into cash back

If you buy fuel and use it in qualifying nontaxable ways, Schedule 1 is not a chore, it is a cash flow tool. Map each gallon to one allowed use, line it up with the right rate, keep the proof, and file on a steady rhythm. When you do that, refunds stop feeling random and start arriving like clockwork. Build the SOP once, run it every quarter, and give your team back the time they need for higher value work.

• Keep your one page checklist at the front of every packet
• Use the mini calculator with locked formulas
• Appoint a quarterly captain so nothing slips
• E‑file when you can, paper only when you must

Common Mistakes We See Every Season

Most denied or delayed Schedule 1 claims trace back to the same handful of errors. Each one is spelled out in the Instructions for Form 8849 and on the Schedule 1 (Form 8849) Rev. May 2020 form, and each one is preventable with a tighter pre-file review.

Reusable Checklists

The three checklists below are built to be pasted into a firm SOP folder or a client engagement template. Each step ties to a specific line, rate, or rule on the Schedule 1 (Form 8849) Rev. May 2020 form so a junior preparer can run the packet without guessing.

Keep 8849 Schedule 1 Season From Stalling

Schedule 1 looks small next to a 1040 or an 1120, but the quarterly cadence is what turns it into a delivery problem. Per the Instructions for Form 8849, the claim must be filed during the first quarter following the last quarter included on the form, and only one Schedule 1 is allowed per quarter, so a missed window pushes gallons into the next aggregation cycle or onto the annual claim path. Stack that against the $750 floor on the Schedule 1 (Form 8849) Rev. May 2020 form and the line-by-line rate table, and a single under-staffed week can quietly cost a client a refund.

The fix is not more hours on the form. It is a repeatable production setup that treats every quarterly claim like a small close, with the same packet, the same reviewer pass, and the same threshold check.

• Open a Schedule 1 claim window on day one of each new quarter and tie its cutoff to the quarter being claimed (open January 1 through March 31 for July through December gallons, and so on).
• Standardize the workpaper around the eight line categories (gasoline, aviation gasoline, undyed diesel, undyed kerosene, kerosene aviation, alternative fuels, diesel-water emulsion, and exported dyed fuels) so nothing leaks between filings.
• Run a type-of-use validator before the rate is applied, since lines 1a, 2b, 3a, 4a, 6, and 7a each accept different code sets and the wrong code is the most common rejection reason.
• Apply the GGE and DGE conversions on lines 6a, 6c, and 6g inside the template, never on the side, so raw-gallon numbers cannot reach column (a).
• Run a $750 threshold check before sign-off and route under-threshold quarters into a tagged aggregation queue instead of dropping them.

This is the kind of structured, line-aware production work our tax outsourcing team runs every quarter, so the rate tables, type-of-use codes, and proof-of-export packs are handled the same way each cycle.

FAQs

What is Schedule 1 on Form 8849 used for

Schedule 1 is how an ultimate purchaser requests a refund of federal excise tax on fuel that was later used for a qualifying nontaxable purpose. You list gallons by fuel, match them to approved uses, apply the correct rate, and support each line with records. This is separate from vendor credits or other excise schedules.

Who should file Schedule 1

You should file if your business bought the fuel, paid federal excise tax, and then used that fuel in a way the IRS treats as nontaxable. That includes off‑highway business, farming, certain government and nonprofit educational uses, some aviation uses, and exports. If you are a registered ultimate vendor, you would typically look to Schedule 2 instead.

How do I know if I meet the minimum threshold

Add the refundable amounts across your lines and confirm the total is at least 750 for the claim period you plan to file. If you are under the threshold, you can wait and aggregate later quarters you have not already claimed, or use the annual procedure if you qualify. Keep the one claim per quarter rule in mind.

Can I claim dyed diesel on Schedule 1

Dyed diesel is usually not claimed on the undyed diesel lines. Dyed fuel most often shows up when you export it, and those claims require a full export packet that ties gallons to proof of export. If you claim undyed diesel or kerosene, include your no visible dye certification.

How do aviation claims work

Split aviation gasoline and aviation kerosene from your ground fuels. Classify each transaction as commercial or noncommercial, then apply the correct rate and keep flight logs with your workpapers. If you export aviation fuel, include export proof just as you would for ground fuels.

How long do refunds take

Electronic filing is typically faster because the software checks for basic errors before your claim is accepted. Paper is allowed but tends to move slower and is harder to track. Either way, store your submission receipt and follow your internal calendar for status checks.

What causes most denials or delays

Missing export proof, duplicate gallons across quarters, wrong type‑of‑use codes for aviation or bus categories, and mixing dyed and undyed diesel on the wrong lines. A short QC checklist, a second pair of eyes, and a clean folder for each quarter will prevent most of these issues.

Do I need special software to file

No, but an IRS approved e‑file provider helps you avoid simple mistakes and keeps your documentation in one place. If you file on paper, mirror the same structure with a neat packet, clear labels, and totals that foot to the return.
