How quarterly estimated taxes work in Vermont for 2026

If you earn income that isn't subject to withholding — freelance and 1099 work, business profit, large investment gains — the IRS expects you to pay tax in four estimated installments during the year rather than in one lump sum at filing. This estimator applies 2026 federal brackets, self-employment tax, and your state income tax to project what each quarterly payment should be so you don't underpay and get hit with a penalty.

The 2026 federal due dates are April 15, June 15, September 15, and the following January 15. Payments are made with Form 1040-ES (federal) and your state's equivalent. The key to avoiding penalties is the "safe harbor" rule: you generally won't owe an underpayment penalty if you pay at least 90% of your current-year tax, or 100% of last year's tax liability (110% if your prior-year AGI exceeded $150,000), whichever is smaller. Paying to the safe harbor is often easier than forecasting a variable freelance year perfectly.

Because the underpayment penalty is calculated quarter by quarter, catching up in Q4 doesn't erase penalties from earlier missed quarters — so it pays to estimate early and pay steadily. Freelancers should remember these estimates must cover both income tax and the full 15.3% self-employment tax, which is why a good default is to set aside 25–30% of net income and reconcile each quarter with this tool.

Vermont uses a graduated state income tax topping out at 8.8%. That state layer stacks on top of federal income tax and FICA, so your estimated quarterly taxes in Vermont is taxed more heavily than in a no-income-tax state at the same income.

Frequently Asked Questions

When are 2026 quarterly estimated taxes due? ▾
The 2026 federal due dates are April 15, June 15, September 15, and January 15, 2027. Federal payments use Form 1040-ES; most states with income tax have their own equivalent form and matching schedule.
How do I avoid an underpayment penalty? ▾
Use the IRS safe harbor: pay at least 90% of your current-year tax or 100% of last year's total tax (110% if your prior-year AGI was over $150,000), whichever is less. Meeting the safe harbor avoids the penalty even if you owe more at filing.
Do quarterly payments include self-employment tax? ▾
Yes. Your estimates must cover both federal (and state) income tax and the full 15.3% self-employment tax. That combined burden is why many freelancers set aside 25–30% of net income for quarterly payments.
What happens if I skip a quarter and pay it all later? ▾
The penalty is computed per quarter, so paying extra in a later quarter does not undo a penalty already accruing from an earlier missed one. Paying something each quarter — even to the safe harbor — is the way to stay penalty-free.

How these numbers are calculated

Every figure on this page is computed from published 2026 tax rules — not estimates or rounded ballparks. Federal income tax uses the seven 2026 brackets and the $16,100 single / $32,200 married standard deduction. FICA applies Social Security at 6.2% up to the $184,500 wage base and Medicare at 1.45% with no cap. Self-employment figures apply the 15.3% SE tax with the standard 50% deductible-portion adjustment.
