Obligation Calendar
Every federal deadline this business actually faces, plus one state's if you want it, each one dated and sourced — so the next one doesn't arrive as a surprise.
What do you owe, and when?
A handful of questions, about two minutes. Federal filing dates for this business, plus one state's if you want them, each one dated and sourced.
Free, and no card. Nothing here is guessed — every date is checked against the issuing authority directly.

Informational only — not legal or tax advice. This lists published federal, Texas, Florida, Washington, Nevada, Wyoming, California, New York, South Dakota, Tennessee, Colorado, North Carolina, Illinois, Georgia, Virginia, Pennsylvania, Michigan, Indiana, Minnesota, South Carolina, Kentucky, Iowa, Alabama, Vermont, Idaho (sales tax only), Maine, and Connecticut due dates for the situation you describe; it doesn't know your specific extensions, penalties already in motion, or any state besides those twenty-six. Confirm with irs.gov, your state's tax authority, or your accountant before relying on it.
One calendar, not a search for each form
Small-business tax obligations aren’t one deadline — they’re a scattered set of forms, each with its own due date, each easy to miss because nothing puts them next to each other. Quarterly estimated tax, payroll returns, contractor 1099s, and a state’s own franchise or sales tax all run on different clocks.
This tool asks a handful of questions about how the business is taxed, whether it runs payroll, and whether it pays contractors — then lays out every date that applies, federal first and Texas, Florida, Washington, Nevada, Wyoming, California, New York, South Dakota, Tennessee, Colorado, North Carolina, Illinois, Georgia, Virginia, Pennsylvania, Michigan, Indiana, Minnesota, South Carolina, Kentucky, Iowa, Alabama, or Vermont beneath it if you want it, each one dated and sourced directly from the IRS, the Texas Comptroller, the Florida Department of Revenue, the Washington Department of Revenue, the Nevada Department of Taxation, the Wyoming Department of Revenue, California's Franchise Tax Board and Department of Tax and Fee Administration, New York's Department of Taxation and Finance, the South Dakota Department of Revenue, the Tennessee Department of Revenue, the Colorado Department of Revenue, the North Carolina Department of Revenue, the Illinois Department of Revenue, the Georgia Department of Revenue, the Virginia Department of Taxation, the Pennsylvania Department of Revenue, the Michigan Department of Treasury, the Indiana Department of Revenue, the Minnesota Department of Revenue, the South Carolina Department of Revenue, the Kentucky Department of Revenue, the Iowa Department of Revenue, the Alabama Department of Revenue, or the Vermont Department of Taxes.
Worked example: Badlands Rock & Gem has twelve South Dakota sales-tax dates in 2026, no South Dakota income-tax date, and a tool that only dates monthly filers →
A rock and gem shop in Wall, South Dakota files sales tax monthly. The Department publishes the dates, weekend moves included. The tool dates a monthly filer and nobody else, and it does not cover five other South Dakota taxes.
Frequently asked questions
Which states does this cover?
Federal, for everyone, plus Texas, Florida, Washington, Nevada, Wyoming, California, New York, South Dakota, Tennessee, Colorado, North Carolina, Illinois, Georgia, Virginia, Pennsylvania, Michigan, Indiana, Minnesota, South Carolina, Kentucky, Iowa, Alabama, Vermont, Idaho (sales tax only for Idaho), Maine, or Connecticut (no individual estimates for Connecticut) — the twenty-six states this tool has verified dates for so far. Every other state is left out on purpose rather than guessed at: a wrong date with this product's name on it is worse than no date at all. More states are next.
How current are these dates?
Every federal and Texas date was checked directly against the IRS or the Texas Comptroller on 22 September 2026; Florida's, Washington's, Nevada's, and Wyoming's were checked against their own tax authority on 24 September 2026; California's, New York's, South Dakota's, and Tennessee's on 25 September 2026; Colorado's and North Carolina's on 26 September 2026; Illinois's and Georgia's on 27 September 2026; Virginia's and Pennsylvania's on 28 September 2026; Michigan's and Indiana's on 29 September 2026 — none carried from memory or a generic template. The federal Form 941/940 dates, Florida's sales-tax dates, Nevada's sales-tax dates, Wyoming's sales-tax dates, California's sales-tax dates, Colorado's sales-tax dates, North Carolina's sales-tax dates, and Illinois's sales-tax dates are computed from each authority's own published rule (a day of the month, or the last day of the month, shifted to the next business day on a weekend or holiday); Washington's, New York's, and South Dakota's dates are transcribed directly from each Department's own published 2026 due-date table, which already has every shift resolved. Tennessee's own due-dates page and its Sales and Use Tax Manual both state the day of the month directly, but neither states a weekend-shift rule, so three of its twelve monthly dates (falling on a weekend in 2026) aren't computed; Virginia's own sales-tax page has the same gap, for the same three months. Pennsylvania's sales-tax guide states a weekend-shift rule only for monthly returns, so that is the only frequency where the tool applies one; Pennsylvania is also the first state with a twice-a-year filing option, and its Department of Revenue states no corporate return or estimated-tax due date this tool could read, so a Pennsylvania C corporation gets a plain note instead of a date. Michigan's dates come from its own estimated-tax voucher, corporate income tax page and 2026 sales, use and withholding forms; one combined return covers all three taxes, and the state's own weekend-and-holiday page moves a due date to the next business day, which is why an annual return due on Sunday, 28 February 2027 shows as Monday, 1 March. Michigan's Accelerated filer tier, elective Flow-Through Entity Tax and city income taxes are not computed. Indiana's dates all come from one page, the Department of Revenue's Tax Filing Deadlines table, checked on 29 September 2026 (its holiday list from the State Personnel Department's holiday page); Indiana splits monthly sales-tax filers by last year's average monthly tax, so the 20th and the 30th are separate schedules, and a monthly filer's January return falls on 2 March because February has no 30th. Indiana withholding, the Financial Institution Tax and pass-through returns are not computed. Georgia's sales-tax dates are also computed from its own published rule, but unlike every other computed state, Georgia's own due-date table directly confirms the fourth-quarter and annual dates too, so neither is left out. California's, New York's, Colorado's, North Carolina's, Illinois's, Georgia's, Virginia's, and Pennsylvania's own estimated-tax installment dates are quoted directly from each state's own tax agency, not computed — Virginia's own first installment is due May 1, not April 15 like every other state's.
Why doesn't this cover local taxes or licences?
There are thousands of local jurisdictions, each changing its own deadlines every year, and a wrong one would still carry this product's name. Federal and state cover where small businesses actually get caught most often; local and licence deadlines are a different, much larger problem this tool doesn't take on.
