Tax payment deadlines depend on what you owe and how you file

Federal income tax is due on April 15 of the year following the tax year. If April 15 falls on a weekend or holiday, the deadline moves to the next business day. State income tax deadlines vary by state — some align with the federal date, others differ by weeks. Payroll taxes (what employers withhold) have different deadlines entirely: federal deposits are due weekly or semi-weekly depending on how much you owe, and quarterly estimated taxes are due on specific dates throughout the year.

The date you owe depends on your filing status and income type. If you're self-employed or have investment income, you may owe quarterly estimated taxes on April 15, June 15, September 15, and January 15 of the following year. If you're an employee, your employer handles withholding, and you settle up on April 15. If you file late or owe more than you've paid in, penalties and interest accrue immediately after the deadline passes.

Key Takeaways

  • Federal income tax is due April 15 each year; state deadlines vary by where you live and work.
  • Self-employed people and those with investment income owe quarterly estimated taxes on April 15, June 15, September 15, and January 15.
  • Penalties start accruing the day after the deadline if you owe money you haven't paid, even if you file an extension.
  • You can pay taxes by check, electronic transfer, credit card, or direct debit, and each method has different processing times and fees.
  • Filing an extension moves your filing deadline to October 15 but does not extend your payment deadline — taxes are still due April 15.

Federal income tax deadlines for employees and filers

If you're a W-2 employee, your employer withholds federal income tax from each paycheck. You don't make a separate payment — instead, you file a tax return by April 15 to either claim a refund or pay any remaining balance. The IRS calls this the individual income tax filing deadline.

If you're filing as self-employed, a business owner, or you have significant investment income, you owe federal income tax directly. You still file by April 15, but you may also owe quarterly estimated taxes throughout the year. These are due on the 15th of April, June, September, and January. If you miss a quarterly payment, penalties begin accruing on that date, regardless of when you file your annual return.

The IRS accepts payments through multiple channels: the IRS Direct Pay system (free, electronic transfer from your bank account), the Electronic Federal Tax Payment System (EFTPS, also free), credit or debit card (through approved payment processors, with a fee), or check mailed to the IRS. Processing times vary: electronic payments typically post within one business day, while checks take 7 to 14 days to clear.

State income tax deadlines and variations

Most states that collect income tax align their deadline with the federal date: April 15. However, some states have different dates. For example, Virginia's deadline is May 1, and a few states allow additional time if you file an extension. Check your state's department of revenue website for the exact date, because missing a state deadline triggers state penalties separate from federal ones.

Some states do not collect income tax at all — including Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live or work in one of these states, you have no state income tax payment due. If you live in one state but work in another, you may owe tax to both, and each has its own deadline and payment method.

State payment methods vary. Most states accept electronic transfer, check, or credit card, but fees and processing times differ. Some state tax agencies charge a fee for credit card payments; others do not. Contact your state's tax authority directly or check their website before paying to confirm the deadline, accepted methods, and any associated costs.

Quarterly estimated tax payments for self-employed and business owners

If you're self-employed, own a business, or receive income that isn't subject to withholding (such as rental income or investment gains), you owe quarterly estimated taxes. These are due on April 15, June 15, September 15, and January 15. The January 15 payment covers the previous calendar year and is technically part of your annual tax filing, but it's still a separate payment with its own deadline.

You calculate estimated taxes by projecting your annual income and tax liability, then dividing by four. If your income is uneven throughout the year, you can adjust each quarterly payment to match. The IRS provides Form 1040-ES to help you calculate the amount. You pay through the same channels as annual taxes: IRS Direct Pay, EFTPS, credit card, or check.

Missing a quarterly payment triggers a penalty immediately. The IRS charges an underpayment penalty that compounds each quarter you miss. Even if you pay everything by April 15 when you file your annual return, you still owe penalties for each missed quarterly deadline. The penalty rate changes quarterly and is based on the federal interest rate plus a percentage set by the IRS.

What happens if you miss the deadline

If you owe taxes and don't pay by the deadline, two penalties begin accruing: a failure-to-pay penalty and interest. The failure-to-pay penalty is typically 0.5% of the unpaid tax per month, up to 25% of the total. Interest compounds daily and is calculated based on the federal rate plus 3%. Both penalties start the day after the deadline and continue until you pay in full.

Filing an extension (Form 4868 for federal taxes) moves your filing deadline to October 15 but does not extend your payment deadline. Taxes are still due April 15. If you file an extension but don't pay by April 15, you owe the same penalties as if you hadn't filed an extension at all. The only benefit of an extension is extra time to file your return; it doesn't reduce what you owe or when you owe it.

If you can't pay the full amount by the deadline, you have options. You can set up a payment plan (installment agreement) with the IRS, which allows you to pay over time. The IRS charges a setup fee and interest continues to accrue, but the failure-to-pay penalty is reduced to 0.25% per month if you have an active payment plan. You can request a payment plan online, by phone, or through a tax professional.

Payroll tax deadlines for employers

If you're an employer, you withhold federal income tax, Social Security tax, and Medicare tax from employee paychecks. These are not your taxes — they belong to your employees and the government. You must deposit them on a schedule set by the IRS based on how much you owe.

Most employers deposit payroll taxes weekly or semi-weekly. If your total tax liability is less than $2,500 per quarter, you may be able to pay quarterly instead. Deposits are made through the Electronic Federal Tax Payment System (EFTPS) or through your bank's payroll system. Missing a payroll tax deposit triggers a penalty that starts at 2% of the unpaid amount and increases based on how late the payment is.

Payroll tax deadlines are separate from income tax deadlines and are much more frequent. If you're unsure of your deposit schedule, the IRS provides a tax deposit coupon (Form 8109) or you can check your account through EFTPS. Employers who consistently miss payroll tax deadlines face serious consequences, including liens on business assets and personal liability for the unpaid taxes.

Payment methods and processing times

The IRS and most state tax agencies accept multiple payment methods, each with different processing times and costs. Electronic transfer through IRS Direct Pay or EFTPS is free and posts within one business day. Credit or debit card payments are processed immediately but carry a fee (typically 1.87% to 2.35% of the payment) charged by the payment processor, not the IRS. Check payments take 7 to 14 days to clear and should be mailed to the address listed on the tax agency's website — using the wrong address delays processing.

If you're paying by credit card, the payment posts to your card account immediately, but the IRS receives the funds after the processor settles the transaction, which typically takes one to two business days. For tax purposes, your payment date is the date the IRS receives the funds, not the date you submitted the payment. If you pay by credit card on April 14, the IRS may not receive it until April 16, which counts as late.

State tax agencies have their own payment systems and fees. Some states accept credit card payments for free; others charge a fee similar to the IRS. Check your state's tax website before paying to confirm the accepted methods, any fees, and the processing timeline. If you're paying multiple states, each has its own deadline and payment system — you cannot make one payment that covers all states.

Frequently Asked Questions

Can I pay my taxes with a credit card without paying a fee?

The IRS itself does not charge a fee for credit card payments, but the payment processors it uses do charge a fee (typically 1.87% to 2.35% of the amount). Some state tax agencies charge no fee for credit card payments, while others do. Check your state's tax website to see if they charge a processing fee. If you want to avoid the fee entirely, use IRS Direct Pay or EFTPS, which are free and funded directly from your bank account.

What if I file an extension — do I get more time to pay?

Filing an extension (Form 4868) gives you until October 15 to file your return, but your payment is still due April 15. If you owe taxes and don't pay by April 15, penalties and interest begin accruing even if you have an extension. The only way to extend your payment deadline is to set up a payment plan with the IRS, which allows you to pay over time while interest and a reduced penalty continue to accrue.

Do I owe quarterly estimated taxes if I'm an employee?

No. If you're a W-2 employee, your employer withholds taxes from each paycheck, and you settle up on April 15 when you file your return. You only owe quarterly estimated taxes if you're self-employed, own a business, or have significant income that isn't subject to withholding, such as rental income, investment gains, or freelance work.

What's the difference between the failure-to-pay penalty and interest?

Interest is the cost of borrowing money from the IRS — it compounds daily and is currently around 8% per year (the rate changes quarterly). The failure-to-pay penalty is a separate charge for not paying on time, typically 0.5% of the unpaid tax per month. Both accrue from the day after the deadline until you pay in full. If you set up a payment plan, the failure-to-pay penalty drops to 0.25% per month, but interest continues.

Can I pay my state taxes through the IRS website?

No. The IRS only processes federal tax payments. State taxes must be paid through your state's tax agency website or by check mailed to the address they provide. Each state has its own payment system, deadline, and accepted methods. Do not send state tax payments to the IRS — they will not be applied to your state account and will cause delays and penalties.
