The first time a client slid a Form 928 across the table, the panic was the usual one: they thought they owed a fuel excise return when the IRS had only asked them to post a bond. That single misread sets up hours of rework. Form 928 is the Taxable Fuel Bond, and it secures the gasoline, diesel fuel, and kerosene tax under sections 4081 and 4041(a)(1). It does not report or pay that tax.

The bond backs a Form 637 excise registration and is posted under section 4101, required only when the IRS specifically imposes it as a condition, not of every registered party. It has three bond-type checkboxes and three fuel-type checkboxes, the amount is capped at expected liability for a representative period, and the surety must give at least 60 days written notice before being relieved. Those signing, surety, and cancellation details are where small errors create big cleanup.

Key Takeaways

• Form 928 is the IRS Taxable Fuel Bond, the bond posted under Internal Revenue Code section 4101 to secure the federal excise tax on gasoline, diesel fuel, or kerosene. It is not an excise tax return; it backs a Form 637 excise tax registration and secures the tax imposed under sections 4081 and 4041(a)(1). You file it in duplicate with the IRS employee who required the bond.
• The bond is required only when the IRS specifically imposes it as a condition of a Form 637 registration. It is not required of every excise-registered party. The current revision is September 2017 (OMB 1545-0725, Catalog Number 16984Z).
• Form 928 has three bond-type checkboxes, original, strengthening, and superseding, and three fuel-type checkboxes, gasoline, diesel fuel, and kerosene. The IRS may require a strengthening or superseding bond when it is needed to ensure collection of the section 4041(a)(1) and 4081 tax.
• The IRS caps the bond amount at expected section 4041(a)(1) and 4081 liability for a representative 6-month period, or, for a terminal operator, the expected section 4081 liability of others on fuel removed at the operator’s racks over a representative 1-month period.
• A surety must give the principal and the IRS at least 60 days written notice before being relieved of liability, and the surety must be listed in Department of the Treasury Circular 570. File Form 928 in duplicate with the IRS employee who required it.

What Form 928 is, and when the IRS requires it

Form 928 is the Taxable Fuel Bond. It is the surety bond a person posts under Internal Revenue Code section 4101 to secure payment of the federal excise tax on taxable fuel. The form itself is short, but it is a legal instrument, not a return, so the language and the signatures matter.

The bond is not something every fuel registrant files. It is required only of a person the IRS specifically directs to post bond as a condition of registration, or to keep an existing registration, on Form 637. From my side of the desk, the first question is always the same: did the IRS put the bonding requirement in writing? If it did not, there is nothing to file yet.

Where the bond fits, Form 637 registration and section 4101

Section 4101 covers registration and bond for taxable fuel activities. When the IRS conditions a Form 637 registration on a bond, Form 928 is the instrument that satisfies that condition. The registration lets the registrant operate in the fuel supply chain; the bond protects the government if the tax does not get paid.

• The bond backs a Form 637 registration. It does not replace the excise tax return, which is filed separately on Form 720.
• File Form 928 in duplicate with the IRS employee who required the bond, not a general service center.
• Keep the written IRS request that imposed the bond in your engagement file, since it defines the scope of what you are securing.

Which tax the bond secures, sections 4081 and 4041(a)(1)

The bond ensures payment of the tax imposed on fuel under section 4081 or section 4041(a)(1). Section 4081 imposes tax on the removal, entry, or sale of gasoline, diesel fuel, and kerosene. Section 4041(a)(1) reaches diesel fuel and kerosene sold for use or used as fuel in a diesel-powered highway vehicle, and similar special-fuel transactions.

Form 928 carries three fuel-type checkboxes, gasoline, diesel fuel, and kerosene. Check the fuel the bond covers so the instrument matches the registrant’s actual activity. Quick rule you can copy into your SOP: the fuel boxes describe what is bonded, not what is taxed on any single transaction.

Original, strengthening, and superseding bonds

Form 928 has three bond-type checkboxes, and choosing the wrong one is one of the easiest ways to leave a registrant exposed. The type controls whether you are starting fresh, adding to an existing bond, or replacing it.

The three bond types

Bond type	What it does	When you use it
Original	The first bond posted for the registration.	A new Form 637 registration where the IRS has imposed a bond.
Strengthening	Adds to the amount of an existing bond. The original bond stays in force.	Expected fuel tax liability has grown and the current bond no longer covers it.
Superseding	Replaces the existing bond entirely.	You are substituting a new bond, for example a new surety, for the old one.

When the IRS can require a new bond

The IRS may require a strengthening or superseding bond in two situations: when it is necessary to ensure collection of the taxes imposed under sections 4041(a)(1) and 4081, or when there is a substantial change in the registrant that affects the adequacy of the existing bond. Small errors create big cleanup, so decide supplement versus replace before you ever touch the checkbox.

Why the distinction matters

Checking strengthening when you mean superseding can leave two bonds legally in force. Checking superseding when you mean strengthening can terminate coverage you still needed. Either error surfaces at the worst possible moment, usually when liability is already rising.

The bond has no fixed term

A Form 928 bond is a continuing obligation. It does not expire on a date the way a return period closes, which is exactly why monitoring, not filing, is where most of the real work lives.

How the bond amount is set

The IRS caps the bond amount based on expected fuel tax liability over a representative period, and the period depends on who the registrant is.

• General rule: the cap is the applicant’s or existing registrant’s expected tax liability under sections 4041(a)(1) and 4081 for a representative 6-month period, as determined by the IRS.
• Terminal operator: the cap is the expected section 4081 tax liability of persons other than the terminal operator on taxable fuel removed at the operator’s racks, measured over a representative 1-month period.

Because the cap tracks expected liability, the right bond amount changes as volume changes. That is the trigger for the strengthening and superseding analysis above.

The three parts of Form 928

Form 928 is organized into three numbered parts. Walking them in order keeps the execution clean.

• Part I, Bonding. This is where the bond is described: the bond type, the fuel covered, the principal and surety, and the bond amount.
• Part II, Signature. Both the principal and the surety sign here under penalties of perjury. A missing or mismatched signature is the most common reason a bond gets bounced.
• Part III, Approval by Internal Revenue Service. Leave this blank. The IRS Authorized Official completes it.

The bond also carries four conditions the principal and surety agree to, starting with the principal’s promise not to attempt to defraud the United States of any tax under section 4041(a)(1) or 4081. Read those conditions before signing, not after.

Who may sign, and the surety requirement

Who may sign as principal

The form defines four signer categories, and the right signer depends on the entity:

• The individual, if the applicant or existing registrant is an individual.
• The president, vice president, or another principal officer, if the registrant is a corporation.
• An authorized member or officer, if the registrant is a partnership or similar entity.
• The fiduciary, if the registrant is a trust or estate.

The surety must be on Circular 570

The surety on the bond must be listed in Department of the Treasury Circular 570 as an acceptable surety or reinsurer on federal bonds. A state insurance license alone is not enough. Confirm the surety appears in Circular 570 before the bond is executed.

How a surety gets released

A surety that wants out must notify both the principal and the IRS in writing at least 60 days before the date it wants to be relieved of liability. That notice cuts off only future liability. The surety stays liable for tax, penalty, and interest tied to acts before cancellation until those amounts are paid. We see this gap every season: teams treat the 60-day notice as a clean exit and miss the tail.

A fast pre-file checklist you can reuse

• Confirm the IRS imposed the bond in writing as a condition of the Form 637 registration.
• Select the bond type, original, strengthening, or superseding, to match supplement-versus-replace.
• Check the fuel type covered, gasoline, diesel fuel, or kerosene.
• Verify the surety is listed in Department of the Treasury Circular 570.
• Set the bond amount against the section 4081 and 4041(a)(1) liability cap for the representative period.
• Match the principal signer to the entity type, and prepare two copies for filing in duplicate.

If you feel lost, start with three questions: did the IRS require it, is the surety eligible, and is the amount right. Then work the rest.

Keeping the bond adequate and in force

Watch volume against the bonded amount

Because the bond amount is capped by expected section 4081 and 4041(a)(1) liability, rising fuel volume can push actual liability past what the current bond covers. Compare each quarter’s gasoline, diesel fuel, and kerosene activity against the volume the bond was based on, and flag any period that runs over.

Diary the surety relief window

The 60-day surety relief notice is easy to miss in a busy quarter. Calendar the window the moment a notice arrives so a cancellation never lapses coverage unnoticed, and confirm the notice actually reached the IRS, not just the principal.

Re-test when the registrant changes

Substantial changes in ownership or management can affect the adequacy of the bond and may trigger a required strengthening or superseding bond. Treat any such change as a prompt to re-run the liability-cap analysis rather than assuming the existing bond still fits.

A simple filing and monitoring flow

• Start from the written IRS request that imposed the bond, and confirm the registrant and Form 637 registration it ties to.
• Build Part I, the bond type, fuel coverage, surety, and amount, against the current liability cap, then execute Part II signatures.
• File both copies in duplicate with the IRS employee who required the bond, and leave Part III for the IRS.
• Keep a small SOP, two pages max, that defines the quarterly adequacy check, the surety-notice diary, and where the bond file lives. A light process saves hours later.

Common pitfalls that slow teams down

Filing before the IRS requires it

Form 928 is not a standing requirement for every fuel registrant. Posting a bond the IRS never asked for wastes effort and can confuse the registration record. Wait for the written bonding condition, then file.

Treating the bond like a return

The bond secures the tax; it does not report or pay it. The excise tax still flows through Form 720. Keep the bond file and the return file separate so neither one stands in for the other.

Letting the amount drift from liability

The cap moves with expected section 4081 and 4041(a)(1) liability. Average numbers hide clusters, so re-test the amount whenever volume jumps, and decide early whether a strengthening or superseding bond is the right fix.

Where teams get stuck, and how to fix the review loop

If your reviewers are buried in redo cycles, formalize the basics. Keep a master SOP for holdings reviews, standardize workpaper names, define a three‑layer review path, and track a simple SLA for turnaround. If you want help operationalizing that, Accountably can plug a trained offshore team into your workflow with SOPs, standardized workpapers, and layered quality control so partners spend less time in review and more time on client strategy. Keep it practical and minimal, no resume dumps, just predictable delivery.

Conclusion

You now know what Form 928 really is: the Taxable Fuel Bond you post under Internal Revenue Code section 4101 to secure the gasoline, diesel fuel, and kerosene excise tax under sections 4081 and 4041(a)(1), filed in duplicate with the IRS employee who required it. Confirm the IRS required the bond, pick the right bond type, use a Circular 570 surety, set the amount to the liability cap, and then monitor it every quarter. Do this consistently and your reviews will run faster, your explanations will be crisper, and your registrations will stay clean.

Common Mistakes We See Every Season

Most Form 928 cleanup traces back to a handful of misunderstandings about what the bond is and how it stays in force. Here are the ones my team flags most often.

Reusable Checklists

These checklists are copy-paste ready for your firm SOPs. Drop them into your excise compliance workflow and adjust the bond amount references to each registrant.

Keep 928 Season From Stalling

Form 928 work does not spike on a calendar the way a return does. The bond is a continuing obligation with no fixed term, so the real workload is staying current: in every quarter where fuel excise liability moves, the principal must contact the IRS to test whether a strengthening or superseding bond is required. The form looks light, the IRS estimates roughly 1 hour 55 minutes of recordkeeping plus another 38 minutes to learn and prepare it per the Paperwork Reduction Act burden estimate, but the monitoring around it is what teams underestimate.

The fix is to treat the bond as a live compliance asset, not a one-time filing. That means assigning ownership for the quarterly adequacy check, watching volume against the bonded amount, and keeping the surety and signing chain documented so a cancellation notice or an ownership change never catches the registrant short on its Form 637 status.

• Track gasoline, diesel fuel, and kerosene volume each quarter against the volume the current bond amount is based on.
• Diary the 60-day surety relief notice window so a cancellation never lapses coverage unnoticed.
• Re-test the section 4081 and 4041(a)(1) liability cap whenever a registrant's expected fuel tax changes.
• Flag substantial ownership or management changes that can trigger a required bond update.
• Keep Part III approvals and the assigned registration number on file with the underlying Form 637 record.

This is the kind of low-frequency, high-stakes monitoring that quietly falls through the cracks when a team is buried in returns. Accountably builds the SOP and the quarterly review cadence into your workflow, so excise bond obligations get tracked the same way every period.

FAQs

What is Form 928?

It is the IRS Taxable Fuel Bond. You post it under Internal Revenue Code section 4101 to secure the federal excise tax on gasoline, diesel fuel, or kerosene under sections 4081 and 4041(a)(1), and you file it in duplicate with the IRS employee who required the bond.

Who has to post a Form 928 bond?

Only a person the IRS specifically requires to post bond as a condition of registration, or to keep an existing registration, on Form 637. It is not required of every excise-tax-registered party; the IRS imposes the bonding condition case by case.

What is the difference between an original, strengthening, and superseding bond?

Form 928 has three bond-type checkboxes. An original bond is the first bond posted. A strengthening bond adds to the amount of an existing bond. A superseding bond replaces the existing bond entirely. The IRS may require a strengthening or superseding bond when it is needed to ensure collection of the tax under sections 4041(a)(1) and 4081.

How much is the Form 928 bond?

The IRS caps the bond amount at the applicant or registrant’s expected section 4041(a)(1) and 4081 tax liability for a representative 6-month period. For a terminal operator, the cap is the expected section 4081 liability of persons other than the operator on taxable fuel removed at the operator’s racks over a representative 1-month period.

How does a surety get released from a Form 928 bond?

The surety must notify the principal and the IRS in writing at least 60 days before it wants to be relieved of liability. That notice ends only future liability; the surety stays liable for tax, penalty, and interest from acts that occurred before cancellation until they are paid. The surety must be listed in Department of the Treasury Circular 570.
