Vermont

Corporate income tax

Form CO-411 is due on the date prescribed for filing the corporation's federal return under the Internal Revenue Code (32 V.S.A. 5862), i.e., the 15th day of the 4th month after the close of the tax year for C corporations. Tax is the greater of the graduated rate schedule (6.0% / 7.0% / 8.5%) or a minimum tax set by Vermont gross receipts.

Extension. A federal extension automatically extends the Vermont filing date to 30 days beyond the federal extended due date...

Partnerships and S corporations

Vermont has NO elective pass-through entity (PTE/PTET) tax as of 2026-09-01: the 2023-2024 S.45 ('An act relating to an elective pass-through entity income tax and credit') passed the Senate only and never became law, and neither the 2025 BI-471 instructions nor the Department's Business Entity Income Tax page mention any election. Entity-level items that DO exist: a $250 minimum entity tax on every BI-471 filer (Form BI-476 for resident-only entities also requires the $250); mandatory nonresident estimated payments (Form WH-435) on Vermont-source income of nonresident owners; composite returns optional, and mandatory for entities with more than 50 nonresident owners.

Sales and use tax

Due date. Returns and payment are due on the 25th day of the month following the reporting period (monthly filers: exception -- the January return is due February 23; quarterly filers: 25th of April, July, October and January; annual filers: January 25). Weekend/holiday due dates roll to the next business day (Department's 2026 calendar shows e.g. Jan 26 / Apr 27 / Jul 27 / Oct 26).

Filing frequency. The Department assigns monthly, quarterly, or annual filing at registration based on the sales and use tax liability for the immediately preceding calendar year (annualized if the business did not operate the full year); the Commissioner may also prescribe other periods.

Thresholds. Statute (32 V.S.A. 9775(a)): prior-year liability of $500 or less = annual (one payment by January 25); more than $500 but less than $2,500 = quarterly; $2,500 or more = monthly. The Department's Sales and Use Tax FAQ states the split more simply as 'exceeded $500 = monthly; $500 or less = quarterly' -- see soft_spots.

Prepayments. None. No prepayment or accelerated-payment schedule is stated on the Department's sales and use tax pages or in 32 V.S.A. 9775.

Notes

Vermont has no franchise tax, no separate LLC fee administered by the Department of Taxes, and no elective PTE tax; the Department's 2026 dates (4/15/2026 CO-411, 3/16/2026 BI-471, 10/15/2026 extended) are for tax year 2025 returns. The annual report is a Secretary of State filing, not bundled with tax filings.
