Self-Employed? Don’t Forget About the Estimated Tax Deadline

Being self-employed comes with many perks—flexibility, independence, and control over your income. But it also brings added responsibilities, especially when it comes to paying taxes. Unlike W-2 employees, self-employed individuals don’t have taxes automatically withheld from their income. Instead, you’re expected to pay estimated taxes throughout the year—typically on a quarterly basis.
Missing an estimated tax deadline can lead to IRS penalties, so it’s crucial to know your responsibilities and stay organized.
Who Needs to Pay Estimated Taxes?
If you’re self-employed, a freelancer, gig worker, or independent contractor, you likely need to pay estimated taxes. The IRS generally requires estimated tax payments if:
- You expect to owe $1,000 or more in federal income tax for the year.
- Your withholding and refundable credits won’t cover at least 90% of your current year’s tax liability, or 100% of last year’s liability, whichever is smaller.
W-2 employees have taxes withheld based on their W-4 form, but as a self-employed individual, you’re responsible for estimating and paying your taxes directly to the IRS.
Quarterly Deadlines for the 2025 Tax Year
Quarter | Income Period | Estimated Due Date |
---|---|---|
Q1 | Jan 1st – Mar 31st, 2025 | April 15th, 2025 (Tuesday) |
Q2 | Apr 1st – May 31st, 2025 | June 16th, 2025 (Monday; June 15th is a Sunday) |
Q3 | Jun 1st – Aug 31st, 2025 | September 15th, 2025 (Monday) |
Q4 | Sep 1st – Dec 31st, 2025 | January 15th, 2026 (Thursday) |
*If the due date falls on a weekend or federal holiday, it shifts to the next business day. You can skip the final payment due in January if you file your tax return and pay your full balance by January 31st.*
How to Calculate Your Estimated Tax Payments

To figure out your estimated taxes, start by projecting your total income for the year and subtracting any business expenses. That gives you your net income, which is what the IRS cares about. You’ll also need to account for self-employment tax (15.3% for Social Security and Medicare) on top of regular income tax.
Use IRS Form 1040-ES to help you calculate how much to pay. It includes instructions and worksheets that guide you through estimating income, deductions, and credits. If your income is steady, divide your total annual tax bill by four. If not, recalculate before each payment.
Example:
Emma is a freelance graphic designer. She expects to earn $80,000 this year and has about $20,000 in deductible business expenses. That leaves $60,000 in net income ($80,000 – $20,000 = $60,000).
She estimates:
- $8,500 in income tax
- $9,180 in self-employment tax (15.3% of $60,000)
- Total estimated tax = $17,680
Divided by four quarters, Emma plans to pay $4,420 every three months. She pays online using the EFTPS system and updates her estimates if income changes.
What Happens If You Underpay?
If you don’t pay enough estimated tax, the IRS may hit you with a penalty. You can usually avoid this if you owe less than $1,000, paid at least 90% of your current year’s taxes, or 100% of last year’s. Certain exceptions—like retirement, disability, or other unusual circumstances—may also apply.
Smart Tips for Staying on Top of Estimated Taxes
Paying estimated taxes doesn’t have to be stressful—as long as you stay organized and plan ahead. Here are some practical tips to help you manage your payments and avoid penalties:
1) Track your income and expenses monthly to avoid surprises at each deadline.
2) Set aside 25–30% of each payment in a dedicated savings account for taxes.
3) Wait to pay until you’ve actually earned income—no need to prepay before you start working.
4) Keep detailed records of each estimated payment made—you’ll need them when filing your return.
5) Overpaid one quarter? You may reduce or skip the next payment—quarterly payments are cumulative.
6) Check your state tax rules—many states require their own estimated payments with separate deadlines.

Estimated taxes are a routine part of self-employment, but with a little planning, they don’t have to be a burden. By tracking your income, staying aware of deadlines, and adjusting as your earnings fluctuate, you can avoid penalties and stay in control of your finances year-round.
