The November 2025 IRS payment deadline applies to estimated tax payments, not regular income tax

If you are self-employed, a freelancer, a business owner, or someone with income that does not have taxes withheld automatically, the IRS requires you to make estimated tax payments four times a year. The November 2025 deadline is for the third quarterly payment of 2025, due on November 18, 2025. This is not a deadline for filing your tax return — it is a payment deadline for taxes you expect to owe on income you have already earned.

Most people with regular W-2 jobs do not need to make estimated payments because their employer withholds taxes from each paycheck. But if you have self-employment income, rental income, investment income, or other sources where no withholding happens, you are responsible for sending the IRS money on a schedule, or you may face penalties and interest when you file your return.

The November deadline is one of four: April 18, 2025 (first quarter), June 16, 2025 (second quarter), September 15, 2025 (third quarter), and January 15, 2026 (fourth quarter). Missing the November payment does not mean you cannot pay later — but the longer you wait, the more interest and penalties accumulate.

Key Takeaways

  • The November 18, 2025 deadline is for the third quarterly estimated tax payment, required only if you have self-employment or other income without automatic withholding.
  • You calculate what you owe based on your expected income for the year, not on what you actually earned in the third quarter alone.
  • You can pay online through IRS Direct Pay, by phone, by mail, or through a tax professional, and payment methods vary in how quickly the IRS receives your money.
  • If you miss the deadline, you can still pay, but the IRS charges interest from the due date and may assess penalties depending on how much you owe and how late you are.
  • Adjusting your estimated payments during the year is normal if your income changes or if you realize you will owe more or less than you thought.

Who actually has to make estimated payments

You are required to make estimated payments if you expect to owe at least $1,000 in federal income tax after accounting for any withholding or credits. This includes self-employed people, business owners, investors, and anyone with significant income that is not subject to employer withholding.

If you are an employee with a W-2 job and also have side income, you may need to make estimated payments on the side income only — or you can ask your employer to withhold extra from your paycheck instead. Some people use that route to avoid making quarterly payments.

Farmers and fishermen have different rules and a later deadline (usually January 31 of the following year), so check IRS Publication 505 if that applies to you.

How to calculate your estimated payment for November

The IRS does not tell you how much to pay — you calculate it yourself. The basic approach is to estimate your total income for the year, subtract deductions, calculate the tax on that amount, subtract any tax already withheld or paid, and divide by four. Each quarterly payment should be roughly one-quarter of your total expected tax liability for the year.

If your income is uneven — for example, you earn more in some months than others — you can use the annualized installment method, which lets you pay different amounts each quarter based on actual income earned so far that year. This can lower your payment if you had a slow start to 2025.

Many people use tax software or work with a tax professional to calculate their estimated payments. The IRS provides Worksheet 1-1 in Publication 505 if you want to do it by hand, but the math is straightforward enough that most tax software will walk you through it.

Payment methods and how long each takes

IRS Direct Pay is free and the fastest option. You go to irs.gov, enter your tax information, and the IRS withdraws money directly from your bank account. The payment posts the same day or the next business day, and you get a confirmation number immediately. This is the safest way to prove you paid on time.

Credit or debit card payments go through a third-party processor (not the IRS directly). You pay a convenience fee of 1.87% to 2.35% of the payment amount, and the processor sends the money to the IRS within one to two business days. This is useful if you want to charge the payment to a card for rewards, but the fee adds up.

Phone payments through the IRS automated system (1-800-829-1040) work the same way as Direct Pay — free and immediate. Mail payments take much longer; the IRS must receive your check by November 18, so you need to mail it several days earlier. Include Form 1040-ES with your payment so the IRS knows which quarter and which year it is for.

Electronic Federal Tax Payment System (EFTPS) is another free option if you have already enrolled. It works like Direct Pay but requires advance setup.

What happens if you miss the November deadline

Missing the deadline does not prevent you from paying. You can pay late, and the IRS will accept it. However, you will owe interest on the unpaid amount from the due date forward. The interest rate changes quarterly and is currently around 8% per year, but check irs.gov for the exact rate for the period you are late.

You may also face an underpayment penalty if you did not pay enough in estimated taxes throughout the year. The penalty is calculated based on how much you underpaid, how late you were, and the interest rate. If you paid at least 90% of your 2025 tax liability or 100% of your 2024 liability (110% if your 2024 adjusted gross income was over $150,000), you can avoid the penalty even if you pay late.

The best approach if you realize you will miss the deadline is to pay as soon as you can. The longer you wait, the more interest accumulates. If you are going to be significantly late, consider paying what you can now and the rest as soon as possible, rather than waiting until you file your return in April.

Adjusting your estimated payments if your income changes

If you have already made payments for the first, second, or third quarters and your income situation changes, you can adjust your fourth-quarter payment (due January 15, 2026) to account for the difference. For example, if business was slower than expected, you can pay less in the fourth quarter. If you earned more, you can pay more.

You do not have to amend earlier payments — the IRS will reconcile everything when you file your return in April. If you overpaid, you will get a refund. If you underpaid, you will owe the difference plus interest and possibly a penalty.

Some people recalculate after each quarter and adjust the next payment. Others make equal payments all year and settle up at tax time. Both approaches work; it depends on whether you want to minimize interest or keep your payments predictable.

Frequently Asked Questions

What if I do not know my income for the whole year yet?

Estimate based on what you expect to earn. If you are self-employed, use your income from the same period last year as a starting point, then adjust up or down based on current business. You can always revise your estimate for the next quarter if you were significantly off. The goal is to get close enough to avoid large underpayment penalties.

Can I pay the November payment late and still avoid penalties?

You can pay late, but you will owe interest from November 18 forward. You may also face an underpayment penalty unless you meet the safe harbor rules (90% of 2025 tax or 100% of 2024 tax). Paying as soon as you realize you will be late minimizes the interest that accrues.

Do I need to file a form with my payment?

If you pay online or by phone, no form is required — the IRS has your information. If you mail a check, include Form 1040-ES (Estimated Tax for Individuals) with your payment so the IRS knows which quarter it covers. Write your Social Security number and "2025 Q3" on the check itself.

What if I already paid too much in estimated taxes?

You will get a refund when you file your return in April. You can also request a refund of overpaid estimated taxes before you file by submitting Form 1040-ES and a letter to the IRS, but most people just wait and claim the refund on their return.

Is there a way to avoid making quarterly payments?

Yes — if you have a W-2 job, you can ask your employer to withhold extra from your paycheck to cover your self-employment or other income. This way, taxes are withheld throughout the year and you do not have to make separate quarterly payments. Adjust your W-4 form with your employer to increase withholding.
