Full answer
Gather your EIN, business details, quarterly transaction records, and information supporting exemptions or credits. Identify each applicable excise tax and calculate it using the current Form 720 instructions. Complete Parts I or II as appropriate, reconcile the total in Part III, and attach required schedules. Schedule A generally reports semimonthly liabilities for Part I taxes, while Schedule C covers qualifying claims.
File electronically through a provider participating in the IRS excise tax e-file program, or mail a signed paper return following the instructions. E-filing Form 720 is optional, not mandatory, but it returns an IRS acknowledgment within days instead of weeks.
Standard quarterly deadlines are April 30, July 31, October 31, and January 31, moved to the next business day when they fall on a weekend or holiday. Some taxes require semimonthly deposits before the return deadline, so do not assume all payments can wait until you file the quarterly return.
