Sales tax

Multi-state sales tax for small business, retired.

The monthly multi-state sales-tax estimate for small business — per-state tally, per-state due date, per-state remittance row, fired by the bookkeeping loop after you wire it up once — so the nine-state return calendar stops being the Sunday the operator rebuilds by hand. The full wire-once beat is on /how-it-works; the Pro tier ($49/mo) names the price the multi-state estimate ships on.

The multi-state remittance tax.

There is another tax small operators pay — one the books record, the CPA reconciles, and the Sunday before the calendar turns turns over with no warning. It is paid in per-state returns filed three days late because the operator forgot which of the seven nexus states runs its remittance on the twentieth — and which of the seven runs it on the twenty-third, or the last day of the month, or the Monday after the third Sunday. The penalty arrives nine days later, on the DOR letterhead, in a CC line the inbox already knows.

A $4,800 order ships to a Texas customer on the eighth. The Texas Comptroller wants 6.25% state + 2% local on the twentieth — that is eight days, not thirty, and not after the quarter closes. The next state over wants the same line filed quarterly on a ST-100, not monthly, with a separate MCTD add-on that the customer’s ship-to triggered because the box crossed a county line. A third state wants the same invoice remitted on the last day of the month, not the twentieth, and a fourth, an island of one among forty-eight, wants it on the twenty-third — three days after everyone else.

By the next remittance cycle the operator is reconciling seven rate bands, seven due dates, seven portals, seven ACH lines — and re-checking each against the rate band the state DOR of record published this quarter, in case a county surtax moved. The hours are paid in unscheduled Sundays, missed family dinners, and the quiet panic a CDTFA late-notice, an NY DTF ST-100-D, or a Texas Comptroller AP-228 follow-up letter carries when it lands on a Wednesday morning with the due date in the line below.

That tax — the one seven state Departments of Revenue publish a rate band for, the one the books already carry as a line item, the one the operator reconciles by hand on the Sunday before it goes out — is the one Stillpost built the multi-state estimate to retire. Same ship-tos, same invoices, same rate bands. The per-state tally runs on the first of the month, the per-state due date is matched against the calendar the state of record publishes, and the per-state remittance row lands in the books threaded to the receipts that built it. The Sunday before the calendar turns is the Sunday your CPA closed on Monday, not the one you will be writing into tonight.

That is the beat. That is the loop. That is what gets handed back.

What the estimate does each month.

Three beats the loop runs on the first of the month for every nexus state — in the order the calendar fires them. Tally, dues-date, post. Each beat folds into the next, and the seven per-state remittance rows your CPA opens on Monday are built while the loop runs, not after you sit down to write them on a Sunday.

  1. Step one01/03

    Tally by ship-to.

    Each invoice lands under the state the box actually shipped to — California on the 31st, Texas on the 20th, Ohio on the 23rd, the seven-state table reconciled against the rate band the DOR of record published — and the per-state liability is the sum of the per-state rate times the per-state receipts, not a percentage of a monthly total.

  2. Step two02/03

    Match the remittance calendar.

    The estimate cards the due-date rule each state already wrote — CDTFA's end-of-month, Texas Comptroller's 20th, NY DTF's quarterly ST-100 on the third-Monday-after-the-15th when the 20th falls on a weekend — so the line that lands in the books is the line that gets paid, not the line that gets refiled because the loop forgot which calendar a state runs on.

  3. Step three03/03

    Post the liability line.

    Each estimate lands at /app/sales-tax threaded to its state, its due date, and the receipts that built it — so the CPA who opens the books on Monday sees seven pays-ready lines, one per nexus state, already split the way the seven filing portals actually ask for them, not a single consolidated lump that has to be re-split the night before.

What it earns its keep on.

Three returns the multi-state estimate ships, measured the way an operator measures them — late notices that stopped arriving, lines that landed pre-split, audit trails the seven DOR letters no longer ask for.

The nine states the estimate bears on.

Nine nexus states, nine remittance calendars, nine rate bands — each one carried on its own pillar page so the loop's per-state tile is built from the per-state cadence the DOR of record published. Pick the pillar the operator carries in their inbox tonight.
