If you earn income that does not have enough tax withheld during the year, you may need to make estimated tax payments. That can include income from freelancing, self-employment, gig work, interest, dividends, rents, capital gains, prizes, taxable Social Security benefits, unemployment compensation, or other income not fully covered by withholding. The IRS describes estimated tax as the method used to pay tax on income that is not subject to withholding. If you have freelance, 1099, creator, or side-business income, see Quarterly Taxes for Freelancers and Side Businesses and Self-Employment Tax Explained.
For tax year 2026, the federal estimated tax deadlines are:
| Payment | Income period covered | Due date |
|---|---|---|
| First estimated tax payment | January 1 to March 31, 2026 | April 15, 2026 |
| Second estimated tax payment | April 1 to May 31, 2026 | June 15, 2026 |
| Third estimated tax payment | June 1 to August 31, 2026 | September 15, 2026 |
| Fourth estimated tax payment | September 1 to December 31, 2026 | January 15, 2027 |
The IRS Form 1040-ES page explains that Form 1040-ES is used to figure and pay estimated tax. The 2026 Form 1040-ES instructions list the four payment due dates as April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027.

Why estimated taxes exist
The federal income tax system is generally pay-as-you-go. Employees usually pay through withholding from their paychecks. But if income is not subject to enough withholding, the IRS may expect the taxpayer to make payments during the year instead of waiting until the return is filed.
Estimated tax may apply to:
- Freelance income
- 1099 income
- Gig economy work
- Self-employment income
- Interest
- Dividends
- Rental income
- Capital gains
- Taxable retirement income without enough withholding
- Taxable Social Security benefits
- Unemployment compensation
- Prizes or awards
The IRS Form 1040-ES overview specifically mentions self-employment earnings, interest, dividends, rents, alimony, unemployment compensation, and the taxable part of Social Security benefits as examples of income that may require estimated tax payments if withholding is not enough.
Who may need to make estimated tax payments in 2026
In most cases, you may need to make estimated tax payments for 2026 if both of these are true:
- You expect to owe at least $1,000 in tax for 2026 after subtracting withholding and refundable credits.
- You expect your withholding and refundable credits to be less than the smaller of 90 percent of your 2026 tax or 100 percent of the tax shown on your 2025 return, assuming your 2025 return covered the full year.
There is an important high-income rule. If your 2025 adjusted gross income was more than $150,000, or more than $75,000 if married filing separately, the 100 percent prior-year amount generally becomes 110 percent instead. See IRS Publication 505 and Form 1040-ES for the detailed rules.
This is why people often hear about estimated tax “safe harbor” rules. The basic idea is that you may be able to avoid an underpayment penalty if you pay enough during the year through withholding, estimated payments, or both.
The dates are called quarterly, but the periods are not equal
Estimated taxes are often called quarterly taxes, but the IRS payment periods are not four equal calendar quarters.
The second payment covers only April and May. The third payment covers June through August. The fourth payment covers September through December.
That uneven schedule can surprise taxpayers. Someone who waits until the end of June to think about “second quarter” taxes may already have missed the June 15 deadline.
What if your income is uneven during the year?
If your income is steady throughout the year, you may be able to divide your estimated tax into four equal payments.
But if your income is uneven, that simple approach may not fit. For example, a freelancer, consultant, seasonal business owner, investor, or real estate professional may earn much more in one part of the year than another.
IRS Publication 505 says that if income is not received evenly throughout the year, the annualized income installment method may reduce the required payment for one or more periods. This method estimates tax based on income, deductions, and other items through the end of each payment period.
That means a taxpayer who earns most of the year’s income late in the year may not necessarily owe the same amount each quarter. But annualized calculations are more complicated and usually require more careful recordkeeping.
What if you miss a payment?
If your estimated tax payments are late or too small, you may be charged an underpayment penalty. The IRS also warns that you can owe a penalty for a specific payment period even if you are due a refund when you file your tax return.
That is one of the most important points to understand. A refund at tax filing time does not always mean every estimated tax deadline was handled correctly.
Can you skip the January 15, 2027 payment?
Possibly.
The 2026 Form 1040-ES instructions say you do not have to make the January 15, 2027 estimated tax payment if you file your 2026 tax return by February 1, 2027 and pay the entire balance due with your return. The date is February 1, 2027 because January 31, 2027 falls on a Sunday.
That exception can be helpful for taxpayers who are ready to file early. But if you are not certain you can file and pay by February 1, 2027, it may be safer to make the fourth estimated payment by January 15, 2027.
Special rule for farmers and fishermen
There is a special estimated tax rule for taxpayers with income from farming or fishing.
If at least two-thirds of your gross income for 2025 or 2026 is from farming or fishing, IRS estimated tax guidance for farming and fishing income says calendar-year taxpayers can pay 2026 estimated tax by January 15, 2027. Alternatively, if they file their 2026 Form 1040 or 1040-SR by March 1, 2027 and pay all tax owed at that time, they do not need to make an estimated tax payment.
How to pay 2026 estimated taxes online
The IRS says taxpayers may pay estimated taxes by mailing Form 1040-ES, paying online, paying by phone, using the IRS2Go app, or paying through an IRS online account.
One common option is IRS Direct Pay. IRS Direct Pay lets taxpayers make payments online directly from a bank account. The IRS describes Direct Pay as free and secure, with no sign-in required.
When using Direct Pay, it is important to choose the correct payment type, tax form, and tax year. For a 2026 estimated tax payment, taxpayers generally need to make sure the payment is applied as an estimated tax payment for the 2026 tax year.
The IRS Direct Pay help page says taxpayers receive a confirmation number for each payment and should keep a copy of that number. A confirmation shows the payment request was submitted, but taxpayers should also check their bank statement or IRS online account to make sure the payment was withdrawn and processed.
Common estimated tax mistakes to avoid
1. Waiting until tax filing season
Estimated tax is designed to be paid during the year. If you wait until filing season, you may have enough money to pay the tax, but still owe a penalty because the payments were not made on time.
2. Treating all four quarters as equal calendar quarters
The second estimated tax payment is due June 15, not June 30. The payment periods are not the same as ordinary calendar quarters.
3. Forgetting investment income
People often think estimated taxes are only for freelancers. But dividends, interest, capital gains, rents, and other income can also create an estimated tax issue if withholding is not enough.
4. Forgetting state estimated taxes
This article focuses on federal estimated taxes. Your state may also require estimated tax payments. State deadlines, rules, forms, and penalties may differ from the federal rules.
5. Not saving proof of payment
Keep your confirmation number, payment date, amount, and tax year. If a payment is misapplied or not processed, those records matter.
Simple planning example
Suppose a freelancer estimates that they will owe $12,000 in federal tax for 2026 after subtracting any expected withholding and refundable credits.
If their income is steady throughout the year, they might plan for four payments of $3,000 each:
| Due date | Example payment |
|---|---|
| April 15, 2026 | $3,000 |
| June 15, 2026 | $3,000 |
| September 15, 2026 | $3,000 |
| January 15, 2027 | $3,000 |
If their income changes during the year, they may need to update the estimate and adjust later payments.
