Vermont estimated tax (quarterly) calculator

Plan quarterly payments based on Vermont tax rules.

How this calculator works

Step 1 estimates your Vermont tax based on the taxable income you provide and the Vermont progressive brackets. The tool adjusts for Vermont-only income using your allocation %.

Step 2 subtracts expected withholding to determine how much is still due for the year. If the remaining tax is under $500, estimated payments are generally not required.

Step 3 divides the remaining tax into four equal payments and lists the standard due dates used by Vermont.

Frequently asked questions

When are Vermont estimated payments due?

Vermont uses the standard quarterly dates: April 15, June 15, September 15, and January 15 of the following year.

What if withholding changes later?

Recalculate with updated withholding to keep your quarterly plan accurate.

Is the safe harbor the same as federal?

Vermont generally requires estimated payments if tax due is $500 or more. Use your prior-year tax liability as a reference point.

Estimates use Vermont’s income tax brackets and are not a substitute for official payment calculations.
