Vermont's unique tax features for 2025

Homestead Declaration requirement

Vermont resident homeowners must file a Homestead Declaration each year by April 15, 2026, even if they don't need to file a personal income tax return. This declaration may qualify them for a Property Tax Credit and helps save on local property taxes.

Community property considerations

Vermont recognizes civil unions and marriage equality, providing specific guidance for tax filing statuses and home office deductions for couples.

Special provisions for farmers

If at least two-thirds of your gross income is derived from farming, you may pay estimated tax at any time on or before January 15, 2026. However, if farmers file their tax return on or before March 1, 2026, and pay the total tax at that time, they need not file an estimated tax.
