When Estimated Tax Payments Are Due and How to Track Them
Estimated tax payments are due four times a year, on dates set by the IRS and your state
Estimated tax is what you pay when you don't have taxes withheld from a paycheck—because you're self-employed, a freelancer, have investment income, or receive other money without automatic withholding. The IRS and your state both expect these payments on specific dates, and missing them can result in penalties and interest, even if you end up overpaying when you file your annual return.
Federal estimated tax payments go to the IRS on four dates each year. The dates are the same nationwide: April 15, June 15, September 15, and January 15 of the following year. If any date falls on a weekend or federal holiday, the deadline moves to the next business day. Your state may use the same dates, different dates, or no estimated tax system at all—this depends entirely on where you live and file.
You are responsible for calculating how much to pay each quarter and sending it in yourself. The IRS does not bill you, and neither does your state. If you underpay, you'll owe penalties when you file your annual return, even if you're due a refund overall. If you overpay, you can request a refund or have the overage credited to next year's taxes.
Key Takeaways
- Federal estimated tax payments are due April 15, June 15, September 15, and January 15, with the same dates applying in most states.
- You calculate the amount yourself based on your expected income for the year, and the IRS provides a worksheet (Form 1040-ES) to help you do this.
- Payments can be made online through IRS Direct Pay, by mail with a voucher, or through a tax professional's payment service.
- Missing a payment deadline triggers penalties and interest on the unpaid amount, even if you end up with a refund when you file your return.
- Some states do not require estimated tax payments, and others use different due dates or have their own payment systems.
How to calculate what you owe each quarter
The IRS provides Form 1040-ES, which includes a worksheet to estimate your total income for the year and calculate your quarterly payment. You'll need to project your self-employment income, rental income, investment gains, and any other money you expect to receive. The form then walks you through subtracting deductions and credits to arrive at your estimated tax liability, which you divide by four.
If your income is unpredictable or you're unsure how much you'll earn, you can use last year's tax return as a starting point. Many people pay based on what they owed the previous year, then adjust if their circumstances change significantly. You can also pay different amounts in different quarters if you know your income will be uneven—for example, higher in summer and lower in winter.
A tax professional or accounting software can calculate this for you, but you remain responsible for the accuracy of the amount. If you underpay intentionally or through carelessness, you'll owe penalties when you file.
Where and how to send federal estimated tax payments
IRS Direct Pay is the fastest and most direct method. You go to irs.gov, enter your payment amount and the quarter you're paying for, and transfer money from your bank account. There is no fee, and the IRS confirms receipt immediately. You can schedule a payment in advance if you want to ensure it arrives by the deadline.
Credit or debit card payments can be made through approved payment processors listed on irs.gov. These processors charge a convenience fee (usually 1.87% to 2.35% of the payment amount), which you pay out of pocket. The fee is not deductible.
Mail payment requires Form 1040-ES voucher. You print the voucher, write a check, and mail both to the IRS address listed on the form. Mail payments must be postmarked by the deadline to be considered on time. This method is slower and riskier if the check is lost or delayed.
Electronic Federal Tax Payment System (EFTPS) is another online option if you enroll in advance. It's free and allows you to schedule payments ahead of time.
State estimated tax payment deadlines and methods
Most states that have an income tax use the same four federal due dates: April 15, June 15, September 15, and January 15. However, some states have different rules. A few states do not require estimated tax payments at all, even if they have an income tax. Others allow you to pay state estimated tax through the federal system, while some require a separate state payment.
To find your state's rules, contact your state tax authority directly or visit its website. State tax agencies typically have their own payment portals or accept payments by mail. Some allow you to pay through a tax professional. The penalties for missing state estimated tax deadlines vary by state and can include interest calculated daily.
If you live in a state with no income tax (such as Florida, Texas, or Wyoming), you have no state estimated tax obligation, though you still owe federal estimated tax if you have self-employment or investment income.
What happens if you miss a payment deadline
Missing an estimated tax payment deadline triggers an underpayment penalty from the IRS. The penalty is calculated on the unpaid amount from the due date until you pay it, using an interest rate that changes quarterly. Even if you end up with a refund when you file your annual return, you still owe the penalty on the shortfall for that quarter.
The IRS does not waive this penalty automatically. You can request a waiver only if you had reasonable cause—for example, a serious illness, a natural disaster, or a significant change in circumstances that you could not have predicted when the payment was due. Simply forgetting or running short on cash does not may have access to.
Your state may impose its own penalty for late or missing estimated tax payments. These penalties are separate from the federal penalty and are calculated according to state law. Some states are more lenient than others, but all charge interest on unpaid amounts.
Adjusting your payments if your income changes
If you realize partway through the year that your income will be significantly higher or lower than you projected, you can recalculate and adjust your remaining quarterly payments. You don't need permission from the IRS to do this—you simply pay a different amount for the next quarter.
For example, if you expected to earn $50,000 but by June you've already earned $40,000, you might increase your remaining payments. Conversely, if business has been slow, you might lower them. The goal is to pay as close to your actual liability as possible to avoid both penalties and a large bill or refund at tax time.
If you make an adjustment, keep a record of your reasoning and the calculation you used. This helps if the IRS questions why your payments changed mid-year.
Tracking your payments and keeping records
Keep a record of every estimated tax payment you make, including the date, amount, method (online, mail, card), and confirmation number if one was issued. The IRS sends a notice if a payment is not received, but delays can happen, and having your own documentation protects you if there's a dispute.
When you file your annual tax return, you'll report all four quarterly payments. The IRS matches these against its records. If a payment was lost in the mail or misapplied, your return will show the discrepancy, and you'll be contacted to resolve it.
Many tax software programs and accounting platforms allow you to log and track estimated tax payments throughout the year. This makes it easier to stay organized and to calculate your remaining liability if your income changes.
Frequently Asked Questions
What if I don't know how much to pay and I'm afraid of penalties?
You can pay based on 100% of your previous year's tax liability (or 110% if your prior-year adjusted gross income was over $150,000). This "safe harbor" rule means you won't owe an underpayment penalty, even if your current year's tax is higher. You'll still owe the additional tax when you file, but no penalty.
Can I make estimated tax payments monthly instead of quarterly?
No. The IRS requires four payments on the specific quarterly dates. You cannot split a quarterly payment into smaller monthly payments. However, you can pay more than one quarter's amount at once if you want to get ahead.
What if I'm married and file jointly—do we each make separate payments?
No. Married couples filing jointly make one combined estimated tax payment. The payment is based on your combined expected income and tax liability. You can pay from either spouse's bank account.
Do I need to make estimated tax payments if I'm also having taxes withheld from a job?
Only if your withholding plus your other income will result in underpayment. For example, if you have a W-2 job where taxes are withheld, but you also have self-employment income, you may need to make estimated payments on the self-employment portion. Use Form 1040-ES to calculate whether you need to pay.
Can I pay estimated taxes for my spouse if they're unable to?
Yes. Either spouse can make the payment from a joint account or from one spouse's individual account. The payment is credited to both of you on your joint return. Make sure the payment is clearly identified with the correct tax year and quarter.
