Quarterly payments are due four times per year, but the intervals between them are not evenly spaced. Most people searching this question are dealing with IRS estimated tax payments, where the four deadlines fall in April, June, September, and January. The gaps between those dates range from two months to four months, which catches many people off guard.
The Four Payment Periods
The IRS divides the tax year into four payment periods, each covering a specific chunk of the calendar. While “quarterly” suggests even three-month intervals, that’s not how it actually works:
- Period 1 (January 1 through March 31): Due April 15
- Period 2 (April 1 through May 31): Due June 15
- Period 3 (June 1 through August 31): Due September 15
- Period 4 (September 1 through December 31): Due January 15 of the following year
Notice the second period covers only two months, while the fourth period stretches across four months. The first and third periods are the only ones that actually span a full three months. This uneven schedule means you have just two months between your first and second payments, then three months before the third, then four months before the final one.
Due Dates for the 2026 Tax Year
For income earned during the 2026 tax year, estimated payments are due on April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. If any of those dates falls on a Saturday, Sunday, or legal holiday, the deadline shifts to the next business day. You won’t owe a late penalty as long as your payment arrives by that adjusted date.
Who Needs to Make These Payments
Quarterly estimated payments apply to people who earn income that doesn’t have taxes automatically withheld. That includes freelancers, independent contractors, small business owners, landlords collecting rental income, and anyone with significant investment earnings. If you’re a W-2 employee whose only income comes from a regular paycheck, your employer handles tax withholding and you typically don’t need to worry about quarterly payments.
Some people fall into both categories. If you have a salaried job but also earn freelance income on the side, you may need to make estimated payments on the freelance portion, or you can ask your employer to increase your paycheck withholding to cover the extra tax.
How Much to Pay Each Quarter
The simplest approach is to estimate your total tax bill for the year and divide it into four equal payments. You can use IRS Form 1040-ES to calculate this based on your expected income, deductions, and credits. If your income fluctuates throughout the year (seasonal work, for example), you can instead pay based on what you actually earned during each period, though this requires more detailed record-keeping.
You don’t need to be exact. The IRS provides safe harbor rules that protect you from penalties even if your estimate falls short. You’ll avoid the underpayment penalty if your total balance due at filing time is less than $1,000, or if you paid at least 90% of your current year’s tax liability, or if you paid 100% of what you owed on last year’s return. For higher earners with adjusted gross income above $150,000 (or $75,000 if married filing separately), that last threshold rises to 110% of the prior year’s tax.
What Happens If You Pay Late
Missing a quarterly deadline triggers the underpayment of estimated tax penalty, calculated on IRS Form 2210. The penalty is based on three factors: how much you underpaid, how long the payment was overdue, and the IRS’s published interest rate for that quarter. It’s essentially an interest charge on the money you should have sent in. The penalty applies separately to each missed period, so being late on one quarter doesn’t necessarily affect the others.
The penalty is relatively modest for small underpayments or short delays, but it adds up if you skip multiple quarters or owe a large amount. Making even a partial payment by each deadline reduces the penalty for that period.
How to Submit Payments
The IRS accepts quarterly payments through several methods. IRS Direct Pay lets you send money directly from a bank account at no cost. The Electronic Federal Tax Payment System (EFTPS) works well if you want to schedule payments in advance. You can also pay by credit or debit card through approved processors, though card payments carry a processing fee. Mailing a check with a payment voucher from Form 1040-ES still works too.
Each payment method posts on a slightly different timeline. Electronic payments through Direct Pay or EFTPS typically process within one to two business days. If you’re paying close to a deadline, electronic options give you more flexibility than mailing a check, which the IRS counts based on the postmark date.
Quarterly Payments Outside of Taxes
The term “quarterly payments” also comes up with insurance premiums, HOA fees, and some subscription services. These billing cycles typically run on standard calendar quarters: January through March, April through June, July through September, and October through December. Each period lasts roughly 90 to 92 days, and payments are usually due at the start of each quarter.
Unlike tax payments, these billing cycles are evenly spaced. If your insurance company or HOA offers a quarterly payment option, you’re paying every three months on a predictable schedule set by the provider. Check your specific agreement for exact due dates, since they vary by company.
