What's Inside
- The 2026 Excel calendar: 12 monthly tabs, every deadline pre-loaded, color-coded by tax type and severity of penalty
- Federal deadlines: quarterly estimates (1040-ES), Form 941 payroll (4 quarters), Form 940 FUTA, Form 1099 series (1099-NEC, 1099-MISC, 1099-K)
- Sales tax: monthly and quarterly state sales tax filing reminders (with notes on Texas, Florida, California, Arizona, Michigan, Illinois, Pennsylvania, Ohio specifics)
- Fuel taxes: federal Form 720 quarterly (gasoline/diesel excise) plus state motor fuel tax filings
- Specialty filings: tobacco license renewals, lottery commission reports, ATM/scratch-off reconciliations, alcohol permits
- Annual filings: property tax, sales tax annual reconciliation, federal Form 1120/1120-S corporate returns, K-1 distribution
Who This Is For
- Independent c-store and gas station owners (1-20 locations)
- 7-Eleven, AMPM, BP, Shell, Chevron, Sunoco franchisees and dealers
- Operators who run their own books or use a CPA but want to verify nothing's slipping through
- Anyone who's been hit with a late-filing penalty in the last 24 months
Why It Matters
Independent c-store operators typically owe filings across 8-14 different tax agencies — federal, state income, state sales, fuel, tobacco, lottery, payroll, property. Missing any single one triggers penalties that compound. The IRS late-filing penalty alone starts at 5% per month, capped at 25%. State penalties stack on top.
This calendar is built specifically for our industry — not the generic 'tax calendar' your CPA's website links to. It includes the specialty filings (fuel, tobacco, lottery) that general accountants frequently miss.
