Vermont Personal Tax Extension Guide

Form IN-151  ·  Individual Income Tax  ·  Personal Filing Guide

Vermont grants an automatic six-month extension for filing personal income tax returns to taxpayers who have been approved for a federal extension by the IRS. The Vermont Department of Taxes aligns with the federal timeline, moving the state filing deadline from April 15, 2026, to October 15, 2026. No separate Vermont extension form is required if you have a federal extension in place.

If you did not file a federal extension, Vermont still allows you to file your state return up to 60 days after April 18 without penalty, as long as no Vermont or federal extension was filed. However, a $50 late filing penalty applies after the 60-day grace period. This makes Vermont one of the more flexible states for taxpayers who missed the extension deadline.

Vermont's extension applies to filing only—not to paying taxes. Any Vermont income tax owed must be paid by April 15, 2026, to avoid penalties and interest.

• ACH Debit (Free): Schedule a payment through myVTax at www.myvtax.vermont.gov. No fee for ACH debit.
• Credit Card: Visit www.mytax.vermont.gov. A 3% convenience fee applies.

Vermont imposes a failure-to-file penalty of 5% of unpaid tax per month, up to 25%. The failure-to-pay penalty is also 5% per month, capped at 25%. Both apply simultaneously if you miss both deadlines.

• File IRS Form 4868 to secure your federal extension.
• Pay Vermont income tax owed by April 15, 2026, using ACH debit (free) at myvtax.vermont.gov.
• File your return by October 15, 2026.

Vermont's extension is flexible—a federal extension extends your state deadline, and even without one, Vermont allows a 60-day grace period. Pay by April 15 and file by October 15, 2026. Use myVTax for fee-free ACH payments.
