You are required to e-file your information returns but genuinely cannot, and paper filing without cover invites IRC §6721 penalties that can reach up to $340 per return. Form 8508 is the way out: a one-year waiver from mandatory electronic filing tied to a single TIN. The catch is timing, the IRS encourages filing at least 45 days before the return due date and only begins processing on January 1 of the year the returns are due.

The threshold that pulls filers in surprises people, because the 10-return rule is aggregated across many information return types, so nine 1099s plus a few W-2s can push you over. Send Form 8508 by fax to 1-877-477-0572 for the fastest handling, or mail it to the Extension of Time Coordinator in Kearneysville, WV. Approve a waiver for original returns and corrections of the same type come along; want to paper file only corrections, and you must request that separately.

Key Takeaways

• Form 8508 is the IRS waiver request from mandatory e‑filing for specific information returns under a single TIN for one tax year. It covers W‑2 series, 1042‑S, 1097‑BTC, 1098 and 1099 series, 3921/3922, 5498 series, 8027, and ACA Forms 1094‑C/1095‑B/1095‑C.
• File it early. The IRS encourages filing at least 45 days before the return due date and begins processing on January 1 of the calendar year the returns are due. Fax is preferred, or mail to the Kearneysville, WV address.
• The 10‑return rule is aggregated across many information returns, so nine 1099s plus a few W‑2s can push you into e‑file territory. Penalties for failing to e‑file without a waiver can reach up to $340 per return.
• If a waiver for original returns is approved, corrections of the same type are covered. If you e‑file originals but want to paper file only corrections, you must request a corrections‑only waiver.
• Reasons that can support a waiver include undue financial hardship, first year of business, federally declared disaster, serious illness, religious beliefs, rural filers without internet, and limited digital literacy, among others recognized in IRS internal guidance.

What Form 8508 actually does

Form 8508 lets you ask the IRS for a one‑year waiver from electronic filing for specified information returns tied to the TIN on the form. One request can cover multiple return types, but it applies only to the forms you check in Block 5 for that TIN and that tax year. The IRS treats the mandate broadly. If you file 10 or more information returns in a calendar year, counted in the aggregate across common types, you generally must e‑file unless you have an approved waiver.

Which forms are covered? The list includes the W‑2 series, the full 1099 and 1098 families (1098 series excludes 1098‑F), 1042‑S, 3921/3922, 5498 series, 1097‑BTC, 8027, plus ACA Forms 1094‑C/1095‑B/1095‑C. The waiver lasts one year and is TIN‑specific. If the IRS grants any of these waivers, it automatically applies to Forms 8300 for that calendar year, though you cannot request a waiver solely for Forms 8300.

Practical example: Your firm plans to e‑file 1095‑C but has a short‑term systems issue with 1099‑NEC and W‑2G. You can request a waiver that lists 1099‑NEC and W‑2G counts in Block 5. The approval, if granted, covers only those types for that TIN in the current year.

When and where to send Form 8508

Timing is everything. The IRS encourages you to submit at least 45 days before your returns are due. For January 31 due dates, that means aiming by mid‑December. The IRS does not process waiver requests before January 1 of the year the returns are due, so plan accordingly and keep proof of submission.

How to submit

• Fax, preferred by the IRS, to 877‑477‑0572 in the U.S., or 304‑579‑4105 internationally.
• Or mail to: Internal Revenue Service, Attn: Extension of Time Coordinator, 240 Murall Drive, Mail Stop 4360, Kearneysville, WV 25430. Submit by one method only, and keep your confirmation.

Penalty reminder: If you were required to e‑file and did not, and you lack an approved waiver, the IRS may assess up to $340 per return. Pair your process with a calendar reminder so your request lands on time.

Form 8508 vs. Form 8508‑I, and a note on IRIS

• Use Form 8508 for the information returns listed above, including ACA Forms 1094‑C/1095‑B/1095‑C.
• Use Form 8508‑I only to request a waiver for Form 8966 (FATCA Report).

If you file via the IRS Information Returns Intake System, IRIS, the paper form still governs the waiver request – and because the IRS has targeted Filing Season 2027 for retirement of the FIRE system, IRIS is expected to become the only intake channel for these returns going forward. The current form instructions note that for a corrections‑only waiver, IRIS filers should leave the corrections box blank on the paper form. This nuance matters when your originals are e‑filed in IRIS but you want permission to paper‑file corrections.

Step‑by‑step completion guide

Block 1, submission type

Pick Original for your first waiver request for the current tax year. Choose Reconsideration only if the IRS denied your earlier request and you are sending new documentation, still within the same tax year window. File at least 45 days before the due date.

Blocks 2–4, issuer and contact

Enter the legal name, full mailing address, and the correct TIN for the filer, plus a reachable contact with phone and email. The waiver is per TIN, so verify the number carefully.

Field	What to get right
Issuer name and address	Match legal records, include ZIP+4 when available
TIN	Nine digits that match IRS records
Contact	Direct phone and monitored email

Keep paragraphs short in your justification later and make sure an authorized person signs.

Block 5, the forms and the counts

Check each return type you want covered and enter two numbers for each, this year’s expected paper filings and next year’s expected paper filings. The IRS uses these counts to scope your waiver. Missing a form here means it is not covered later.

Step‑by‑step completion guide, continued

Block 5, the forms and the counts

Check every return type you want covered, then add two numbers for each, how many you expect to file on paper this year and how many next year. The IRS scopes your waiver to the exact items you mark in Block 5, so if it is not checked, it is not covered. One Form 8508 can include several return types for the same TIN.

Practical tip: build your list from last year’s activity plus current year changes, for example, new contractors that add 1099‑NEC, a new entity that adds W‑2 or 1095‑C, or a stock plan event that triggers 3921 and 3922. If you are unsure about volumes, enter a reasonable estimate. The IRS expects approximations, not exact counts.

Block 7, corrections‑only

Mark “Yes” only if you want a waiver that applies to corrected returns when your original returns will be e‑filed. If you request and receive a waiver for original returns, corrections of that same type are already covered. IRIS filers should leave Block 7 blank on the paper form, this note appears right on the form.

Request a corrections‑only waiver when you e‑file originals but need permission to file only your corrections on paper. Originals that are waived automatically cover corrections for that type.

Block 8, first‑time request

If this is your first‑ever waiver request for any of the forms you checked in Block 5, select “Yes” and skip to the signature line. The IRS states that your first request will be automatically granted for the current year. If you have requested a waiver in the past, select “No” and include your justification (two current third-party cost estimates are required only for undue financial hardship requests; other accepted categories like disaster impact, serious illness, first year of business, or foreign filers unable to obtain software do not require the cost estimates).

Block 9, justification and cost estimates

Only complete Block 9 when your request is based on undue financial hardship. You must attach two current cost estimates from third parties, for example software, programming, or service bureau fees to produce an e‑file. Estimates from prior years are not accepted. Other acceptable reasons do not require the cost estimates, for example disaster impact, serious illness, first year of business, or a foreign filer unable to obtain software.

Model language for your attachment

• We are requesting a waiver due to undue financial hardship. Enclosed are two current cost estimates for software and third‑party preparation needed to comply with the e‑file requirement. These costs exceed our costs to produce paper filings for the current year.
• Our business experienced a declared disaster that disrupted records and systems needed to e‑file. We can file correct paper returns by the deadline.
• This is our first year of operations. Our systems and staffing are not yet prepared to e‑file, and we will comply via paper filing this year.

Block 10, signature

The taxpayer, or a person authorized to sign legally binding documents for the taxpayer, must sign. A transmitter cannot sign unless there is a valid power of attorney attached.

When to file, where to send, and how the IRS evaluates it

• File at least 45 days before the due date of the information returns you want covered. Requests are processed beginning January 1 of the calendar year the returns are due.
• Fax, preferred by the IRS, to 877‑477‑0572 in the U.S., or 304‑579‑4105 internationally. Or mail to: Internal Revenue Service, Attn: Extension of Time Coordinator, 240 Murall Drive, Mail Stop 4360, Kearneysville, WV 25430. Send by one method only. Keep your confirmation.
• The waiver applies to the current year only and to the specific forms you checked for the TIN on the request – you cannot request a waiver for a prior or future calendar year. If you need a waiver next year, reapply.

Penalty note: if you are required to e‑file, you fail to do so, and you do not have an approved waiver, the IRS may assess a penalty. In 2025 instructions for information returns, the maximum standard penalty tier reaches $340 per return for intentional disregard, and penalties for failure to e‑file apply only to the count above the 10‑return threshold. Amounts are indexed and can change, so check the current general instructions.

A simple date planner for January deadlines

Scenario	Return due	Waiver timing target	Latest practical send date
W‑2, 1099‑NEC due Jan 31	Jan 31, 2026	Mid‑December 2025	Early January 2026, noting IRS begins processing Jan 1
1095‑C due Feb/March, electronic	Spring 2026	At least 45 days prior	Mid‑January 2026

Always keep proof of fax or certified mail. If you cut it close, include a brief cover page with your contact info so TSO can reach you quickly.

What forms are covered, exactly

Form 8508 covers the W‑2 family, 1042‑S, 1097‑BTC, 1098 series except 1098‑F, 1099 series except 1099‑QA, 3921, 3922, 5498 series except 5498‑QA, 8027, and ACA Forms 1095‑B, 1095‑C, plus the authoritative 1094‑C transmittal. The approval is TIN‑specific and current‑year only. Use Form 8508‑I only for Form 8966, FATCA.

Special cases worth calling out

Religious‑belief exemption

If using the required technology conflicts with your religious beliefs, you are exempt from e‑filing. You do not have to file a waiver, although you may file Form 8508 with a statement so the IRS records the exemption, and once the IRS records it you do not need to refile in subsequent years. Keep documentation in your files in case of a penalty notice.

Corrections and IRIS

The e‑file mandate does not apply separately to originals and corrections. If your originals must be e‑filed, then corrections must be e‑filed too unless a corrections‑only waiver is approved. IRIS filers leave Block 7 blank on the form.

Real‑world examples

• Systems outage, January 20. Your payroll team can print W‑2s, but your SSA e‑file uploader will not be restored in time. You file Form 8508 by fax with a short note and, if needed, two cost estimates from vendors to produce an electronic file this season. You receive the approval letter and mail W‑2s.
• First year of operations. Your company opened in August. You check Yes in Block 8, skip Block 9, sign, and fax the request. The first‑time request is automatically granted for the current year.
• Corrections‑only. You e‑filed 1095‑C originals, then discovered TIN errors on a small subset. You want to send paper corrections. You request a corrections‑only waiver in Block 7.

Common mistakes that slow or sink a waiver

These checklists are copy-paste ready for your firm SOP. Drop them into the engagement template or the year-end information return binder and adjust the line items to match the client's form mix and TIN structure.

Where to get and send the form

Download the current fillable PDF of Form 8508 and follow the two‑page instructions on the back. Submit by fax or mail only, and keep your proof of submission and approval letter with your year‑end binder. If you are filing Form 8027 on paper under an approved waiver, include a copy of the waiver with those paper Forms 8027 (this attachment requirement applies only to Form 8027 – do not attach the waiver to any other paper information returns filed under the same waiver).

A quick word on support If your firm’s roadblock is not knowledge but capacity, structure, or review time, you are not alone. We have seen firms stall because delivery becomes the ceiling. Accountably operates as a U.S.‑led offshore partner that builds disciplined delivery with SOPs, structured workpapers, and multi‑layer review. If you need help with standardized workpapers, clean review notes, or meeting hard year‑end deadlines without burning out your team, talk with us about a controlled delivery model, not resume farming. Keep client trust high and your advisory time protected. (We mention this only where useful, since this guide is primarily educational.)

A simple checklist you can print

Use this to keep your request clean, complete, and on time.

• Confirm you actually need a waiver. Total your information returns across types to see if you hit the e‑file threshold.
• Pick your return types. List every form family you want covered in Block 5.
• Choose your submission type in Block 1. Original for a first request this year. Reconsideration only if you are adding new support after a denial.
• Complete issuer details in Blocks 2–4. Match legal name, address, and TIN, and add a reachable contact.
• Decide on corrections. If you will e‑file originals but want paper for corrections, mark Block 7.
• First‑time filer. If this is your first waiver for the forms you checked, set Block 8 to Yes.
• Hardship request. If Block 8 is No and you claim undue financial hardship, add two current cost estimates and a short explanation in Block 9.
• Signature. Have an authorized person sign and date in Block 10.
• Submit once by fax or mail. Keep your confirmation and a copy of the packet.
• Track the response. File the approval letter with your year‑end binder and share it with payroll or AP.

Cover sheet

Subject, Form 8508, Waiver Request for [TIN], [Tax Year] We request a waiver from electronic filing for the checked information returns in Block 5 for [Tax Year]. Contact [Name, Title], [Phone], [Email] with any questions. We are submitting this request at least 45 days before the due date.

Hardship note

We request a waiver due to undue financial hardship. Enclosed are two current cost estimates for software and service bureau fees needed to produce valid electronic files. These costs exceed our ability to implement in time for this filing season. We will file correct paper returns by the deadline.

Field‑tested tips from our year‑end desk

• Build a single counts sheet. Tally W‑2, 1099 families, 1042‑S, 1095‑B/C, and anything unusual like 3921 or 3922. This prevents gaps in Block 5.
• Lock your signer early. Calendar a 20‑minute slot so the signature and send do not slip.
• Keep a copy with your binder. If a notice arrives in summer, you can respond fast with proof.
• Pair the waiver with clean workpapers. Reviewers move quicker when schedules, naming, and versioning are consistent.

If capacity is your roadblock, not the rules

If the form itself is clear but your team is underwater, you may need structure, not more hours. At Accountably, we integrate trained offshore teams into your systems with SOP‑driven execution, standardized workpapers, and multi‑layer review so partners are not trapped in review loops. If you want production stability for busy season while protecting quality and security, we can help design a delivery model that holds up at scale. Brief chat, clear scope, documented workflow, and steady turnaround.

Final word and next steps

You now have the playbook. Confirm that you need a waiver, choose the forms, fill the boxes, include any required support, and send it at least 45 days before your due date. Save your proof, track the response, and file on time. If this is your first year, use the first‑time path. If only corrections need relief, request that specifically. Do the simple things right and you will reduce risk, keep clients informed, and move through year‑end with fewer surprises.

Reusable Checklists

Form 8508 season runs on a hidden countdown. Because the IRS asks for the waiver request at least 45 days before each information return due date (per the current Form 8508 instructions), a W-2 or 1099-NEC waiver targeting the January 31 deadline has to land by mid-December, right when most teams are still closing December books and chasing year-end vendor data. Miss the window and the issuer is exposed to IRC §6721 penalties of up to $340 per information return for intentional disregard (per the inflation-adjusted penalty schedule referenced in the General Instructions for Certain Information Returns).

The fix is not a louder reminder email; it is a documented intake step that surfaces the waiver decision in October, paired with a packet template that travels with the engagement. When the prep work is staged, the request itself is short. The form is two pages and the IRS estimates about 45 minutes to complete it (per the Form 8508 paperwork burden statement).

• Run an aggregate-count test in October: under TD 9972, the 10-return e-file threshold is the total across W-2, 1099 series, 1042-S, 1095-B/C, 5498 series, and the other Block 5 form types. It is not per form type. Four 1099-NECs plus two 1042-S plus two 1095-Bs plus two W-2s already totals ten.
• Pre-populate Block 5a paper counts from the prior-year filing log and adjust Block 5b for known mid-year changes (acquired entities, new state registrations, vendor consolidation).
• Lock fax-or-mail in the SOP. Fax to 1-877-477-0572 is the IRS preferred channel; the alternative is mail to the Extension of Time Coordinator in Kearneysville, WV. Choose one path per request so duplicate records do not slow IRS processing.
• Track first-time-waiver clients separately from hardship clients. The first-time path (Block 8 marked YES, skip to Block 10) is auto-approved; the hardship path requires two current third-party cost estimates and a longer review.
• For FIRE users, start the IRS Information Return Application for Transmitter Control Code now. The IRS targets Filing Season 2027 for FIRE retirement and recommends submitting the IR Application for TCC by November 1 with about 45 business days of processing time, so a delayed application is one of the most common reasons filers end up needing Form 8508 in their first filing year.

When the intake test, the packet template, and the 45-day timing line up with the rest of the year-end pipeline, Form 8508 stops being the file that almost slipped through. Our tax preparation and review delivery integrates these waiver workflows into the same calendar as the 1099 prep, W-2 audit, and information return reconciliation, so the December lookahead becomes a checklist instead of a fire drill.

Keep 8508 Season From Stalling

Form 8508 lives in a narrow pre-filing window. The IRS encourages submission at least 45 days before the information return due date, and waiver processing starts January 1 of the calendar year the returns are due. That puts the request directly inside the December close and January filing prep stretch, when teams are already running at peak workload. Treasury Decision 9972 lowered the aggregate e-filing threshold to 10 information returns (per the General Instructions for Certain Information Returns), so the pool of filers who need a waiver expanded sharply after 2024 while the 45-day timing rule itself stayed unchanged.

The fix is to pull the waiver decision forward into the year-end planning cycle and treat Form 8508 as a separate workstream from the actual information return prep. Build the aggregate-count test in October, lock the packet template before December, and stage the submission so the 45-day clock is met without colliding with the January 31 IRS deadlines for W-2 and 1099-NEC filings.

• Block 1 and Block 8 path triage. First-time requesters mark YES in Block 8 and skip from there directly to Block 10 for signature; the form auto-approves them. Subsequent requests based on undue financial hardship need Block 9 documentation; other accepted categories like disaster impact, serious illness, first year of business, or foreign filers unable to obtain software do not require cost estimates. A 'Reconsideration' in Block 1 means adding evidence to a denied request, not submitting a fresh original.
• Block 9 cost-estimate hygiene. Hardship waivers require two current third-party cost estimates comparing electronic vs paper filing for this tax year. Single estimates, prior-year estimates, or estimates that do not specifically address electronic file preparation will trigger automatic denial.
• Block 7 rule for IRIS filers. Leave Block 7 blank for IRIS submissions regardless of whether the waiver covers originals, corrections, or both. With FIRE targeted for retirement at Tax Year 2026/Filing Season 2027 (per IRS Publication 1220), any SOP that auto-checks Block 7 will produce processing issues during the transition.
• Form 8508 vs Form 8809 vs Form 15397. Form 8508 waives the e-filing requirement; Form 8809 grants a 30-day extension to file with the IRS; Form 15397 extends the recipient-statement furnishing deadline. Train intake to route correctly so a request to extend a deadline does not get filed as a waiver.
• Transmitter signature gate. A transmitter or outsourcing partner cannot sign Form 8508 on the issuer's behalf without a Form 2848 Power of Attorney attached. Build the POA verification into the engagement letter for any client where the transmitter is handling submission.

A separate intake queue, a tested packet template, and the 45-day clock pulled forward to October keep the waiver out of the January crunch. Accountably's offshore tax delivery runs the Form 8508 workflow on the same calendar as the W-2 audit and 1099 prep, so the waiver decision is settled before the information return deadline pressure arrives.

FAQs

What is Form 8508?

Form 8508 is the IRS request for a one‑year waiver from mandatory e‑filing of certain information returns under a single TIN. You list the return types you want covered, sign, and submit by fax or mail at least 45 days before the due date. If approved, you can paper file those returns for that year. Always check the current IRS instructions for any changes.

Is a first‑time request really simpler?

Yes. If this is your first waiver for the forms you checked, you mark first‑time in Block 8, skip hardship cost estimates, sign, and send. Still file early and keep proof, because the approval applies only to that tax year and TIN.

What if my originals are e‑filed but only corrections need paper?

Ask for a corrections‑only waiver in Block 7. If your waiver covers originals, corrections are automatically covered for that type. If originals are e‑filed, you need permission to mail corrections.

Who must file Form 8948?

Paid preparers file Form 8948 when they are required to e‑file an individual income tax return but cannot, usually because the taxpayer opts out or a valid exception applies. It documents why a paper submission is allowed. Review the current Form 8948 instructions for the specific criteria.

What is IRS Form 8832 used for?

Form 8832 lets eligible entities choose or change their federal tax classification, for example partnership to corporation. If you want S corporation status, use Form 2553 instead. Confirm effective dates and late election relief in the current instructions.

Who needs to file Form 8858?

U.S. persons that directly, indirectly, or constructively own certain interests in foreign disregarded entities or foreign branches file Form 8858. It reports the entity’s activities and the U.S. owner’s information. Because this is a complex international filing, check thresholds and definitions with current guidance.

What happens if my waiver is denied?

You must e‑file the covered returns by their due date or extended due date. If you believe the denial missed a fact, you can submit a reconsideration with additional documentation within the same tax year window. Keep your timeline tight, and consider alternate e‑file paths if the deadline is close.

Do states honor an IRS waiver?

An IRS waiver covers only federal filings. Some states have their own e‑file mandates and waiver processes. Check each state’s rules, especially for W‑2 and 1099 reporting.
