What the IRS December 2025 Payment Deadline Means for Your Taxes

The IRS December 2025 payment deadline depends on which tax you owe

The IRS sets different payment deadlines throughout the year based on the type of tax and when it was due. December 2025 has specific deadlines for certain payments, but there is no single "December payment" that applies to everyone. If you received a notice about a December deadline, it refers to a particular tax obligation — most commonly quarterly estimated tax payments, payroll taxes if you run a business, or a balance due from your 2024 tax return.

The most common December deadline homeowners and self-employed people face is the fourth quarterly estimated tax payment, due December 15, 2025. This applies if you have income the IRS expects you to pay tax on throughout the year rather than having it withheld by an employer — rental income, self-employment income, investment gains, or retirement distributions. Missing this deadline triggers penalties and interest, even if you end up owing nothing when you file your annual return.

If you received a bill or notice from the IRS with a December date, check what type of tax it covers. The notice itself will state whether it is for income tax, self-employment tax, payroll tax, or another category. That tells you whether the deadline applies to you and what happens if you miss it.

Key Takeaways

• December 15, 2025 is the deadline for the fourth quarterly estimated tax payment if you have self-employment or investment income not subject to withholding.
• Payroll tax deposits and other business tax payments have their own December deadlines that differ from individual income tax deadlines.
• Missing a December deadline results in penalties and interest added to what you owe, even if your total tax liability for the year is zero.
• If you cannot pay by the deadline, you can request a short-term extension or set up a payment plan with the IRS to avoid additional penalties.
• The IRS accepts payments online through IRS.gov, by phone, by mail, or through a tax professional, and each method has different processing times.

Quarterly estimated tax payments and who owes them

Quarterly estimated tax payments are due four times per year if you have income that is not subject to withholding. This includes self-employment income, rental income, capital gains, dividends, and distributions from retirement accounts. The IRS expects you to pay tax on this income as you earn it, rather than waiting until you file your annual return in April.

The four quarterly deadlines are April 15, June 15, September 15, and December 15. If you miss the December 15 deadline, the IRS charges a failure-to-pay penalty on top of any interest owed on the unpaid tax. The penalty is typically 0.5% of the unpaid tax per month, though it can be reduced or waived if you have a reasonable cause for the late payment.

You do not have to make quarterly payments if your withholding from wages or other sources covers your expected tax liability for the year. If you are unsure whether you owe quarterly payments, the IRS Form 1040-ES walks through the calculation, or a tax professional can review your situation.

Payroll tax and business tax deadlines in December

If you operate a business and have employees, you have payroll tax deposits due throughout the year on a schedule determined by how much payroll tax you owe. December deposits follow the same schedule as other months — the due date depends on whether you are a semi-weekly or monthly depositor. Semi-weekly depositors typically have deposits due on Wednesdays and Fridays; monthly depositors have one deposit due by the 15th of the following month.

Self-employed people who do not have employees still owe self-employment tax, which is handled through quarterly estimated payments rather than separate payroll deposits. The December 15 deadline applies to your fourth quarterly payment, which includes both income tax and self-employment tax.

If you received a notice about a December payroll tax deadline and you are unsure of your deposit schedule, contact the IRS at 800-829-1040 or check your account on IRS.gov. Payroll tax penalties are steeper than income tax penalties, so confirming the correct date is worth the call.

What happens if you miss the December deadline

Missing a tax payment deadline triggers two separate charges: a failure-to-pay penalty and interest on the unpaid amount. The failure-to-pay penalty is 0.5% of the unpaid tax per month or partial month, up to a maximum of 25%. Interest accrues daily at a rate set by the IRS each quarter — for 2025, the rate is 8% per year, though this changes quarterly.

These charges apply even if you ultimately owe no tax when you file your return. For example, if you made a large estimated payment in September and then earned less income than expected, you might end up with a refund. You still owe the penalty and interest on the December payment you missed, though you can claim a credit for the overpayment when you file.

The IRS does not automatically waive penalties for first-time late payments. However, you can request penalty relief by filing Form 843 (Claim for Refund and Request for Abatement) if you have reasonable cause — a serious illness, a death in the family, or reliance on incorrect advice from a tax professional are examples the IRS recognizes. The request must be filed within three years of the original due date.

How to pay by the December deadline

The IRS offers several ways to pay a December tax bill, and the method you choose affects how quickly the payment is processed. Online payment through IRS.gov is the fastest and most reliable option — payments are typically applied to your account within one business day. You can pay directly from your bank account or by credit or debit card, though credit card payments include a processing fee charged by the payment processor, not the IRS.

Phone payments are also available by calling 800-829-1040 and speaking with an IRS representative. This method takes longer to process than online payment but allows you to ask questions about your account at the same time. Mail payments should be sent at least one week before the deadline to account for postal delays; include your tax ID and a note indicating which tax period the payment covers.

If you use a tax professional or payroll service, they can submit the payment on your behalf. Confirm with them that they have submitted it by the deadline — the IRS considers the payment made on the date it is received or processed, not the date you give the money to your representative.

Requesting an extension or payment plan if you cannot pay

If you cannot pay by December 15, you have options that reduce or eliminate the failure-to-pay penalty. A short-term extension gives you up to 120 days to pay without the failure-to-pay penalty, though interest continues to accrue. You can request a short-term extension online through IRS.gov, by phone, or by mail.

For longer-term relief, the IRS offers installment agreements that let you pay over time. A short-term installment agreement covers payment within 180 days; a long-term agreement extends beyond that. Both require you to pay interest and a setup fee, but they stop the failure-to-pay penalty from growing. You can set up an installment agreement online through IRS.gov, and the process takes minutes.

If you are facing genuine financial hardship, you can request Currently Not Collectible status, which temporarily pauses collection activity. This does not erase the debt, but it stops penalties from accruing while you recover financially. This option requires documentation of your income and expenses and is typically granted for 12 months at a time.

Checking your payment status and account

After you make a payment, you can verify it was received and applied to your account through IRS.gov. The "Where's My Payment?" tool shows the status of payments made within the past year. Payments made online typically show as received within one business day; mailed or phone payments take longer.

If you made a payment and it does not appear in your account after the expected time, contact the IRS with your payment confirmation number or receipt. Keep any documentation you have — a bank statement showing the payment was deducted, a confirmation email from IRS.gov, or a receipt from your tax professional. This documentation proves you paid on time if there is ever a dispute.

Your IRS account also shows your balance due, any penalties or interest charged, and upcoming payment deadlines. Checking your account regularly helps you catch notices early and avoid missing future deadlines.

Frequently Asked Questions

Is December 15, 2025 the deadline for everyone's taxes?

No. December 15 applies only to quarterly estimated tax payments for people with self-employment or investment income. If you are an employee with taxes withheld from your paycheck, you do not have a December payment deadline. Your annual tax return is due April 15, 2026.

What if I paid late but the IRS has not sent me a penalty notice yet?

The IRS calculates and bills penalties separately from the original tax bill, so a notice may arrive weeks or months after the deadline. You can still request penalty relief by filing Form 843 within three years of the due date, even if you have not received a bill yet.

Can I pay my December tax bill with a credit card without a fee?

No. Credit card payments to the IRS always include a processing fee, typically 1.87% to 2.35% of the payment amount, charged by the payment processor. Paying directly from your bank account online has no fee.

If I set up a payment plan, do I still owe interest?

Yes. A payment plan stops the failure-to-pay penalty from growing, but interest continues to accrue on the unpaid balance at the IRS rate for that quarter. You also pay a setup fee, typically $31 to $225 depending on the type of agreement.

What if I cannot find the December deadline notice the IRS sent me?

Log into your IRS account on IRS.gov to see your balance due and any payment deadlines. You can also call 800-829-1040 and provide your tax ID to have a representative look up your account. Having your Social Security number or EIN and a recent tax return handy speeds up the call.
