About this bond

What it is and who needs it.

What the diesel fuel bond actually covers

Anyone who refines, blends, imports, or otherwise handles taxable diesel fuel must register with the IRS under 26 U.S.C. §4101 using Form 637. As part of that registration the IRS applies an adequate-security test — and where it is not satisfied, it can require a taxable fuel bond.

The bond is filed on IRS Form 928. Under its terms you agree not to attempt to defraud the United States of any tax, to file all required returns, and to pay the diesel excise tax under §4081 or §4041(a)(1), including penalties and interest. If you do not, the United States can recover against the bond.

The penal sum is keyed to your estimated quarterly excise tax liability for the fuel you handle. If that liability rises or falls materially, the IRS may ask for a strengthening or superseding bond — we re-issue at the new amount, with pricing starting from $100 and no credit section in the application.

26 U.S.C. §4101 · 26 CFR §48.4101-1 (Form 928)Registration for taxable-fuel activities is required under 26 U.S.C. §4101 and 26 CFR §48.4101-1, which lets the IRS condition registration on an adequate-security (bond) test. The bond is posted on IRS Form 928 (Taxable Fuel Bond) and guarantees the diesel excise tax imposed by §4081 / §4041(a)(1). The penal sum is set by the IRS from your estimated liability — confirm the amount on your IRS correspondence.

FAQ

Common questions.

How much is the federal diesel fuel tax bond?This bond is priced at 0.75% of the bond amount, with a $100 minimum — your exact price appears at the application. The penal sum itself is set by the IRS from your estimated diesel excise tax liability for the registration period. Enter that figure and apply.

Do all fuel registrants need this bond?No. The IRS requires a taxable fuel bond only when its adequate-security test is not otherwise satisfied — often for newer or higher-risk registrants. Established registrants frequently meet the test without posting a bond.

Which form is the bond filed on?IRS Form 928, the Taxable Fuel Bond, posted under §4101. We issue the executed bond ready to submit with your Form 637 registration or in response to the IRS notice that requested it.

Is there a credit check?The application collects no credit information. Most applications approve instantly; if a check ever runs on a larger bond amount, it is a soft pull that never affects your credit score.

What if my fuel volume changes?If your quarterly excise liability rises or falls materially, the IRS may ask for a strengthening or superseding bond. Send us the new penal sum and we re-issue, with pricing starting from $100.
