Pennsylvania Form PA-40 ES – Estimated Income Tax Payment Vouchers (2026)
Last reviewed: 2025-11-09
Use the Pennsylvania Tax Form Calculator Pennsylvania Form PA-40 ES – Estimated Income Tax Payment Vouchers as a stand alone tax form calculator to quickly calculate specific amounts for your 2026 Pennsylvania state tax return. Alternatively, you can use one of our Combined Federal and State Tax Estimators to quickly calculate your salary, tax, and take-home pay.
Form PA-40 ES provides estimated income tax vouchers for Pennsylvania residents who expect to owe at least $500 in net tax after withholding and credits. The state’s 3.07% flat tax rate applies to all taxable income, and quarterly estimated payments help you avoid underpayment penalties. Individuals, sole proprietors, and retirees often use this form when they do not have enough tax withheld through wages or pensions.
PA requires estimated payments if your annual tax liability exceeds the withholding and credit total by more than $500. Use this calculator to estimate your quarterly amounts.
When to File and Pay
Payments are due in four equal installments:
- 1st Quarter: April 15 (current tax year)
- 2nd Quarter: June 15
- 3rd Quarter: September 15
- 4th Quarter: January 15 of the following year
Each voucher includes your Social Security number and the tax year. If you file jointly, list both spouses on the same form. Payments can be made online via myPATH or by mailing a check with the printed voucher to the Pennsylvania Department of Revenue.

Example Scenarios
Example 1 – Self-Employed Worker: Dana expects to earn $80,000 from freelance consulting and has no withholding. Estimated PA tax = $80,000 × 3.07% = $2,456. She pays $614 each quarter using PA-40 ES vouchers to remain penalty-free.
Example 2 – Retiree: Mark receives $60,000 in pension income and $2,000 in dividends, but only $1,000 is withheld. His estimated liability = ($62,000 × 3.07%) − $1,000 = $904. Since it exceeds the $500 threshold, he must make estimated payments of $226 per quarter.
Common Mistakes to Avoid
- Forgetting to update income projections mid-year if income changes significantly.
- Submitting late payments — interest applies automatically.
- Not reconciling estimated payments with the final Form PA-40.
- Writing the wrong year or SSN on paper vouchers — this delays crediting payments.

Frequently Asked Questions
Why participate in Schedule P donations?
It’s an easy way to support Pennsylvania programs directly from your refund — helping local veterans, children, and conservation efforts without extra paperwork or payments.
Can part-year residents claim the credit?
Yes, if they meet the residency and income rules for the portion of the year they were Pennsylvania residents. Each spouse must file a separate SP form if filing jointly.
Can corporate partners use Schedule B?
Yes, if dividends flow through from partnerships or S corporations.
How do I handle per-diem or expense allowances?
Reimbursements under an accountable plan aren’t taxable; nonaccountable allowances generally are. For UE deductions, only certain unreimbursed expenses qualify in PA.
How does marriage affect local taxes?
EIT/LST are assessed per individual; marriage doesn’t combine incomes for EIT. Each spouse’s PSD/rate applies to their own wages.
