How do I set up quarterly estimated tax payments?

Set up quarterly estimated tax payments using IRS Direct Pay or EFTPS at IRS.gov. Estimate your expected tax liability for the year, divide by four, and pay by each quarterly deadline (April 15, June 15, September 15, January 15). You owe estimated taxes if you expect to owe at least $1,000 after withholding.

Educational content — not tax advice

This page describes general IRS rules for estimated tax payments. Your exact payment amount depends on your income, deductions, and credits. Verify deadlines and current thresholds at IRS.gov and consult a qualified tax professional before making estimated payment decisions.

The U.S. tax system is pay-as-you-go. Employees have taxes withheld from each paycheck; freelancers, self-employed individuals, and investors with significant non-withheld income must make estimated payments instead. Failing to pay enough during the year — whether through withholding or estimated payments — results in an underpayment penalty when you file. IRS Form 1040-ES is the official starting point for calculating and paying estimated taxes.

Who needs to make estimated tax payments?

• Freelancers, independent contractors, and gig workers whose clients do not withhold taxes from payments.
• Self-employed business owners — sole proprietors, single-member LLCs, partners in a partnership.
• Investors with significant capital gains, dividends, or interest income not covered by withholding.
• Employees whose withholding is insufficient — e.g., if you have significant side income or claim too many allowances.
• The IRS threshold: you generally owe estimated taxes if you expect to owe at least $1,000 in tax after subtracting withholding and credits.

Step 1: Estimate your annual tax liability

Use IRS Form 1040-ES — which includes a built-in estimated tax worksheet — to calculate your expected income, deductions, and resulting tax liability for the year. If this is your first year with self-employment income, use last year's return as a baseline and adjust for expected changes. A simpler safe harbor: pay at least 100% of last year's tax liability (110% if your prior-year AGI exceeded $150,000). Meeting this safe harbor avoids the underpayment penalty even if your actual tax bill turns out higher.

Step 2: Divide by four and know the deadlines

Estimated taxes are paid in four installments. The IRS quarterly due dates for 2025 are: April 15, June 16, September 15, and January 15, 2026. Note that the quarterly periods are not equal — the second quarter covers only April 1–May 31, while the third covers June 1–August 31. If income is uneven throughout the year, the IRS annualized income installment method (Form 2210) lets you calculate each payment based on actual income earned in each period, which can reduce penalties for seasonal or irregular income.

Step 3: Pay via IRS Direct Pay or EFTPS

1. IRS Direct Pay (irs.gov/payments/direct-pay): No registration required. Pay directly from a bank account. Payments post in 1–2 business days. Best for occasional payers.
2. EFTPS — Electronic Federal Tax Payment System (eftps.gov): Requires one-time enrollment with your bank account and EIN or SSN. Lets you schedule payments in advance and view payment history. Best for recurring quarterly payers — you can schedule all four installments at once.
3. Mail (Form 1040-ES voucher + check): Least convenient; use certified mail and keep the receipt. Payment is credited on the date mailed.
4. IRS2Go app: Mobile access to Direct Pay for on-the-go payments.

Step 4: Track payments for your tax return

Keep a record of every estimated payment — date, amount, and confirmation number. When you file your annual return, you'll report total estimated tax payments on Form 1040, which are credited against your final tax liability. If you overpaid, you'll receive a refund or can apply the credit to the following year. If you underpaid, you'll owe the balance plus a potential underpayment penalty calculated on IRS Form 2210.

IRS rules to know

• The IRS underpayment penalty applies when total withholding and estimated payments are less than the smaller of: 90% of the current year's tax liability, or 100% of the prior year's tax liability (110% if prior-year AGI exceeded $150,000). — IRS — Estimated Taxes (Topic 306)
• IRS Form 1040-ES includes a Estimated Tax Worksheet to calculate the required payment amount and mailing addresses for paper vouchers. — IRS Form 1040-ES
• EFTPS (Electronic Federal Tax Payment System) is a free IRS service that allows taxpayers to schedule and make federal tax payments electronically — available at eftps.gov. — IRS — EFTPS

Key takeaways

• You owe estimated taxes if you expect to owe $1,000+ after withholding — this applies to most self-employed people.
• Safe harbor: pay 100% of last year's tax (110% if prior-year AGI > $150,000) to avoid underpayment penalties.
• EFTPS lets you schedule all four quarterly payments at once — the most reliable setup.
• Due dates: April 15, June 15, September 15, January 15 — mark your calendar before anything else.
• Keep every payment confirmation number; you'll need it when filing your annual return.
