The Four Quarterly Payment important date Each Year

The IRS sets four fixed dates each year when estimated tax payments are due. These dates do not change based on weekends or holidays — if the important date falls on a Saturday, Sunday, or federal holiday, the due date moves to the next business day. The four quarters run on a calendar basis, not a fiscal year basis, so they align with January, April, July, and October.

The actual payment dates are April 15, June 15, September 15, and January 15 of the following year. The January 15 important date is the one that catches people off guard because it belongs to the next tax year — you pay it in January 2025 for income you earned in 2024. If you miss a important date, the IRS charges a penalty and interest on the unpaid amount, even if you end up with a refund when you file your annual return.

Key Takeaways

  • Quarterly payments are due on April 15, June 15, September 15, and January 15 of the following year, with the due date moving to the next business day if it falls on a weekend or holiday.
  • You owe quarterly payments if you expect to owe $1,000 or more in taxes for the year and your withholding from a job or other source will not cover it.
  • The IRS calculates penalties based on the federal short-term interest rate plus 3 percent, compounded daily, so missing a payment costs money even if you pay everything when you file your return.
  • You can pay online through IRS Direct Pay, by mail with Form 1040-ES, or through an authorized payment processor, and each method posts on different timelines.

Who Has to Make Quarterly Payments

You owe quarterly payments if you are self-employed, have investment income, receive rental income, or have other income sources where no employer withholds taxes. The IRS requires them if you expect to owe $1,000 or more in taxes for the year after subtracting any withholding and credits. If you have a job where your employer withholds taxes, you may not need to make quarterly payments — the withholding covers your tax bill.

The threshold is $1,000 for most people, but it is $500 if you are married filing separately. If you underpay in one quarter, you cannot make up the difference in a later quarter without owing a penalty on the underpayment for that specific quarter. The penalty applies even if you overpay in another quarter or get a refund at tax time.

How to Calculate What You Owe Each Quarter

The IRS provides Form 1040-ES, which includes a worksheet to estimate your total tax for the year and divide it by four. You estimate your income for the full year, subtract deductions, calculate the tax on that amount, and then divide by four to get your quarterly payment. This method works if your income is steady throughout the year.

If your income is uneven — for example, you earn most of your money in the fall — you can use the annualized income method, which calculates tax based on actual income earned through each quarter rather than an even split. This method requires more detailed tracking but can lower your payments in quarters when you earn less. You report which method you used when you file your annual return, and the IRS adjusts any penalties if you underpaid using the wrong approach.

Many self-employed people use tax software or work with an accountant to calculate quarterly payments, since getting the amount wrong triggers penalties. If you cannot estimate accurately, you can pay based on your prior year's tax liability — paying one-quarter of last year's total tax each quarter — and adjust when you have better information.

Payment Methods and Processing Times

IRS Direct Pay is the fastest method. You go to irs.gov, enter your payment information, and the money is withdrawn from your bank account on the date you choose. Direct Pay posts when ready and costs nothing. The payment is considered on time if you schedule it before midnight Eastern Time on the due date, even if the money does not leave your account until the next day.

Paying by mail with Form 1040-ES takes longer. You write a check, include the form, and mail it to the address shown on the form for your state. The IRS considers the payment on time if it is postmarked by the due date, but mail can take a week or more to arrive and be processed. If you mail a check and it arrives late, the postmark date determines whether you owe a penalty.

You can also pay through an authorized payment processor — companies like PayPal, Stripe, or bank bill-pay systems. These processors charge a fee (usually 1.5 to 2 percent of the payment) and have their own processing timelines. Some post the same day; others take one to two business days. Check the processor's terms before paying to confirm the important date they use.

What Happens If You Miss a important date

Missing a quarterly payment important date triggers two separate charges: an underpayment penalty and interest. The penalty is calculated based on the federal short-term interest rate plus 3 percent, compounded daily. The rate changes quarterly and is published by the IRS in early January, April, July, and October. As of early 2024, the rate is around 8 percent annually, but it varies.

The penalty applies to the unpaid amount for each day it is late, from the due date until you pay. If you underpay by $2,000 and do not pay until you file your return six months later, you owe the penalty on that $2,000 for all six months. The IRS does not waive the penalty even if you end up with a refund when you file your annual return — the penalty is separate from your final tax bill.

You can request a waiver of the penalty if you have reasonable cause — for example, a serious illness, death in the family, or a natural disaster. You must file Form 2210 with your annual return and explain the reason. The IRS does not grant waivers for straightforward oversights or cash flow problems, but it does consider them for genuine hardships. If you have a history of paying on time, the IRS is more likely to grant a waiver.

Adjusting Payments If Your Income Changes

If you earn significantly more or less than you estimated, you can adjust your remaining quarterly payments. You do not have to wait until tax time to correct an underpayment. If you underpaid in the first quarter and realize it in June, you can increase your second-quarter payment to catch up. The IRS will still charge a penalty on the first-quarter underpayment, but you stop the penalty from growing by paying the correct amount going forward.

If you overpay early in the year and your income drops, you can reduce your later payments. You recalculate using Form 1040-ES and pay the new amount for the remaining quarters. When you file your annual return, the IRS compares your total quarterly payments to your actual tax liability and either refunds the overpayment or applies it to next year's taxes.

Some people pay the same amount every quarter and then settle up when they file their return. This approach is simpler but means you might owe a large amount in April or get a large refund. The penalty applies to any underpayment in a specific quarter, so paying unevenly can cost more in penalties than paying evenly, even if your total payment is the same.

Frequently Asked Questions

What if the due date falls on a weekend or holiday?

The due date automatically moves to the next business day. If April 15 falls on a Saturday, your payment is due on Monday, April 17. The IRS publishes the adjusted dates each year, so check irs.gov if a important date falls near a weekend. Paying on the original date does not help — the IRS uses the adjusted date to determine if you are late.

Can I pay all four quarters at once instead of making separate payments?

Yes. You can pay your entire year's estimated tax in one lump sum on the first important date (April 15) if you want. However, the IRS still calculates the penalty based on when each quarter's portion was due. If you pay everything on April 15, you owe a penalty on the June, September, and January portions for being early — wait, that is backwards. You owe a penalty on the June, September, and January portions for being late if you do not pay them by their important date. Paying early does not help with later quarters.

Do I need to make quarterly payments if I have a job and am self-employed?

It depends on your total expected tax. If your job withholds enough to cover your total tax liability (including self-employment tax), you may not need quarterly payments. Use Form 1040-ES to calculate whether your withholding plus any credits will cover what you owe. If it will not, you owe quarterly payments on the shortfall. You can also adjust your W-4 at your job to increase withholding instead of making quarterly payments.

What if I did not know I was supposed to make quarterly payments?

The IRS still charges a penalty, but you can request a waiver by filing Form 2210 with your annual return and explaining that you did not know. First-time underpayments are more likely to receive a waiver than repeat ones. If you discover the requirement mid-year, start making payments for the remaining quarters to limit the penalty.

How do I know if my payment was received on time?

If you use IRS Direct Pay, you get a confirmation number when ready. If you mail a check, keep a copy of the postmark as proof. If you use a payment processor, save the confirmation email or receipt. The IRS processes payments slowly, so do not assume a payment is late just because it has not appeared in your account yet. Check your payment status on irs.gov using your Social Security number and the amount you paid.
