The four payment dates for estimated taxes each year
The IRS sets four fixed dates each year when you must send estimated tax payments if you owe them. These dates do not change, and they fall roughly every three months. Missing a payment date can result in penalties and interest, even if you end up overpaying for the year overall.
The four dates are April 15, June 15, September 15, and January 15 of the following year. Each payment covers the income you earned during a three-month period called a quarter. If any of these dates falls on a weekend or federal holiday, the important date moves to the next business day — for example, if April 15 is a Saturday, you have until Monday April 17.
You send these payments to the IRS directly, not to your employer or a state agency. The IRS accepts payments online through its Direct Pay system, by phone, by mail, or through an authorized payment processor. Each method has different cutoff times on the important date date itself, so if you are paying on the last day, check which method you plan to use.
Key Takeaways
- Estimated tax payments are due April 15, June 15, September 15, and January 15, with each payment covering three months of income.
- If a payment date falls on a weekend or holiday, you have until the next business day to pay without penalty.
- You calculate each payment based on your expected income for that quarter, not on what you actually earned.
- Missing a payment date triggers penalties and interest even if your total withholding for the year is correct.
- The IRS Direct Pay system and authorized payment processors let you pay online with no fee, and both show confirmation when ready.
Who must make estimated tax payments
You must make estimated tax payments if you expect to owe at least $1,000 in taxes for the year after subtracting any withholding from a job or other sources. This threshold applies whether you are self-employed, have investment income, or receive income that does not have taxes withheld automatically.
If you are an employee and your employer withholds taxes from your paycheck, you typically do not make estimated payments — your withholding covers your tax bill. However, if you also have self-employment income, rental income, or significant investment income on top of your job, you may need to make estimated payments for the additional income.
Retirees who receive distributions from retirement accounts, Social Security recipients with other income, and people who receive alimony or gambling winnings may also owe estimated taxes. The key question is whether your total tax bill for the year will exceed what is already being withheld or paid through other means.
How to calculate your estimated payment amount
You calculate each quarterly payment by estimating your income for that three-month period, subtracting deductions you expect to claim, and explore the tax rate that matches your filing status and income level. The IRS Form 1040-ES walks through this calculation and provides the tax tables you need. You do not have to divide your annual estimate into four equal payments — you can pay more in quarters when you earn more and less in quarters when you earn less.
Many people estimate conservatively by using their prior year's income as a starting point, then adjusting up or down based on what they expect to change. If your income is uneven — for example, if you are a contractor who gets large invoices in certain months — you can weight your payments toward the quarters when you expect to earn more.
If you pay too little in estimated taxes, you will owe the shortfall when you file your tax return, plus interest and possibly a penalty. If you pay too much, the IRS will refund the overpayment or let you carry it forward to next year's estimated payments. There is no advantage to overpaying early in the year.
How to pay your estimated taxes
The IRS Direct Pay system is the most straightforward method. You go to irs.gov, enter your payment amount and which quarter it covers, and authorize a bank transfer from your checking or savings account. There is no fee, and you receive a confirmation number when ready. Direct Pay works for all four quarterly payments and for amended payments if you need to adjust an earlier quarter.
You can also pay by phone through the IRS at 1-800-829-1040, or by mail by sending a check with Form 1040-ES to the address listed in the form instructions for your state. If you use a tax preparation software or work with a tax professional, they can often submit your payment on your behalf through their own payment processor, though some charge a small fee for this service.
Credit card and debit card payments are available through third-party payment processors authorized by the IRS. These processors charge a convenience fee (usually 1.87% to 2.35% of the payment amount), so you pay more than you would through Direct Pay or a bank transfer. The processors are listed on the IRS website and include companies like PayPal, Stripe, and others.
What happens if you miss a payment date
If you miss a payment date, the IRS charges a penalty based on how much you underpaid and how long you were late. The penalty is calculated as a percentage of the unpaid amount and compounds daily. You also owe interest on the unpaid balance from the original due date until you pay.
The penalty does not disappear when you file your tax return and pay the remaining balance. Instead, it carries forward as part of what you owe. The IRS may waive the penalty if you can show reasonable cause — for example, if you had a serious illness or death in your family during the quarter — but you must request this in writing after you file your return.
If you realize you will miss a payment date, paying even a partial amount by the important date is better than paying nothing. A partial payment reduces the penalty on the unpaid portion and shows the IRS you made an effort to comply.
Adjusting your payments during the year
You can change your estimated payment amount for any quarter if your income changes. If you earn significantly less than you expected in the first half of the year, you can reduce your third and fourth quarter payments. If you earn more, you can increase them. You do not need permission from the IRS to make these adjustments — you straightforward calculate a new amount and pay it by the next important date.
Some people use a safe harbor method to avoid penalties. If you pay either 90% of your current year's tax bill or 100% of your prior year's tax bill (110% if your prior year income was over $150,000), you will not owe a penalty even if your actual tax bill is higher. This method is useful if your income is unpredictable or if you want to avoid calculating quarterly estimates.
If you underpay in early quarters but catch up by paying more in later quarters, you may still owe a penalty on the early underpayment. The IRS calculates penalties quarter by quarter, not on your total for the year. This is why adjusting your payments as soon as you realize your income will differ from your estimate is important.
State estimated tax payments
Many states that have an income tax also require estimated tax payments on their own schedule. Some states use the same four dates as the IRS; others have different important date. A few states require estimated payments only if you owe above a certain threshold, which may differ from the federal $1,000 rule.
You pay state estimated taxes to your state tax agency, not to the IRS. The payment methods vary by state — some accept online payments through their tax department website, while others require a check by mail. Check your state's tax agency website to confirm the dates and methods for your state.
If you live in a state with no income tax, you only make federal estimated payments. If you live in one state but earn income in another, you may owe estimated payments to both states, depending on where the income was earned and where you live.
Frequently Asked Questions
What if April 15 falls on a weekend?
The important date moves to the next business day. If April 15 is a Saturday, you have until Monday April 17. If it is a Sunday, you have until Monday April 16. The same rule applies to June 15, September 15, and January 15 if they fall on weekends or federal holidays.
Can I pay all four quarters at once instead of four separate payments?
Yes. You can pay your entire estimated tax for the year in one lump sum on April 15 if you want. However, if you underpay, you will owe a penalty on the shortfall from April 15 forward, even though you did not miss the important date. Spreading payments across the year reduces the penalty if you underpay.
Do I need to file Form 1040-ES with the IRS when I make a payment?
No. Form 1040-ES is a worksheet you use to calculate your payment amount. You do not send it to the IRS. You only send the payment itself through Direct Pay, by check, by phone, or through an authorized processor. Keep a copy of your payment confirmation for your records.
What if I overpay my estimated taxes?
When you file your tax return, the IRS will refund the overpayment to you, or you can choose to carry it forward as a credit toward next year's estimated taxes. There is no penalty for overpaying, but you also do not earn interest on the overpayment.
Can my tax professional or accountant pay my estimated taxes for me?
Yes. Many tax professionals can submit your estimated tax payment on your behalf through their payment processor. Ask whether they charge a fee for this service, as some do. You remain responsible for ensuring the payment is made by the important date, so confirm with them that it was submitted.
