Do I Need to Make Estimated Tax Payments?
Many taxpayers assume taxes are only due when they file their annual return. However, if enough tax is not paid throughout the year through withholding or estimated payments, the IRS may assess penalties—even if you pay your tax bill in full by the filing deadline.
Not every taxpayer is required to file a federal income tax return. If you're unsure whether you must file, see our article regarding Filing Requirements
Understanding when estimated tax payments are required can help you avoid unexpected tax bills and underpayment penalties.
What Are Estimated Tax Payments?
Estimated tax payments are periodic payments made directly to the IRS during the year to cover income tax and, when applicable, self-employment tax.
They are commonly required for taxpayers who receive income that is not subject to withholding, including:
Self-employment income
Independent contractor income
Rental income
Investment income
Interest and dividends
Capital gains
Retirement income with insufficient withholding
Certain gambling winnings
Who Should Consider Making Estimated Tax Payments?
You should review your tax situation if you expect:
To owe federal income tax after subtracting withholding and refundable credits.
To have significant income without tax withholding.
Your withholding has decreased.
Your income has increased significantly during the year.
Many first-year business owners are surprised that taxes are not automatically withheld from self-employment income.
If you use your personal vehicle for your business, you may also qualify for a business vehicle expense deduction. Learn more in our article, Can I Deduct My Vehicle Expenses for My Business?
How Does the IRS Determine If Payments Are Required?
Generally, estimated tax payments should be considered if you expect to owe at least $1,000 in federal tax after subtracting withholding and refundable credits.
The IRS also provides "safe harbor" rules. In many cases, taxpayers can avoid an underpayment penalty if they pay, through withholding and estimated payments, at least:
90% of the current year's total tax, or
100% of the prior year's total tax (110% for certain higher-income taxpayers).
These rules are designed to prevent penalties when income changes from year to year.
When Are Estimated Tax Payments Due?
Estimated tax payments are generally due four times each year.
Typical due dates are:
April 15th
June 15th
September 15th
January 15th of the following year
If a due date falls on a weekend or federal holiday, the deadline is generally the next business day.
Remember: Missing one payment can result in an underpayment penalty, even if you pay your entire balance when filing your tax return.
How Do I Make Estimated Tax Payments?
The IRS currently offers several ways to make estimated tax payments, with electronic payment methods preferred:
IRS Direct Pay is available to individual taxpayers and does not require enrollment. (recommended for most individuals)
IRS Online Account
Electronic Federal Tax Payment System (EFTPS) requires enrollment before first use, so it's best for taxpayers who make recurring payments or businesses.
Debit card, credit card, or digital wallet are processed by IRS-authorized third-party processors, and convenience fees apply.
Note: The IRS is transitioning toward electronic payments. While some paper payment methods may still be available during the transition, taxpayers should review current IRS payment guidance before mailing a payment. Electronic payment methods provide immediate confirmation and simplify recordkeeping.
What Happens If I Don't Pay Enough?
If you do not pay enough tax throughout the year, the IRS may assess an underpayment penalty.
If you receive a notice from the IRS regarding estimated tax or an underpayment penalty, don't ignore it. Our article What Should I Do If I Receive an IRS Notice? explains what these notices mean and the steps you should take.
The penalty is generally based on:
The amount underpaid
The length of time the payment was late
The applicable interest rate
Paying the balance with your tax return does not automatically eliminate the penalty.
Can I Increase My Withholding Instead?
Yes.
For many employees and retirees, increasing federal income tax withholding can reduce or eliminate the need to make quarterly estimated tax payments.
This may be easier than making separate quarterly payments because withholding is generally treated as if it were paid evenly throughout the year, even if increased later in the year.
Example: Sarah is a W-2 employee who starts a weekend consulting business. No taxes are withheld from her consulting income. Midway through the year, she realizes she'll owe additional tax. She may be able to avoid an underpayment penalty by increasing her withholding from her W-2 job or making estimated tax payments before the remaining due dates.
Keep Good Records
Maintain copies of:
Estimated tax payment confirmations
IRS payment receipts
Bank confirmations
Annual tax projections
Records of withholding
Prior-year tax returns
Good records help verify payments and make tax preparation easier.
Common Mistakes
Avoid these common errors:
❌ Waiting until April to pay the entire balance.
❌ Forgetting investment income may require estimated payments.
❌ Assuming withholding from one job covers all income.
❌ Missing quarterly due dates.
❌ Ignoring changes in income during the year.
Frequently Asked Questions
Do I have to make estimated tax payments if I'm self-employed?
Not always. It depends on your expected tax liability after accounting for withholding and credits. Many self-employed taxpayers do need to make estimated payments.
What if my income changes during the year?
You may be able to adjust future estimated payments to reflect your current income. This is one reason it's beneficial to review your tax situation periodically rather than waiting until year-end.
Can I avoid estimated tax payments by increasing my withholding?
Often, yes. Increasing withholding from wages or certain retirement distributions may reduce or eliminate the need for separate estimated payments.
