When you work for yourself, nobody reminds you when taxes are due. There is no employer withholding money from each paycheck, so the dates are your responsibility. Missing one can mean penalties and interest.
This guide lists the main federal deadlines for the 2026 tax year and the first half of the 2027 cycle, plus what each date means for you. Dates move when they land on a weekend or federal holiday, so we’ve adjusted for that. This article is educational, not personalized tax advice. Always confirm dates on IRS.gov.
The Big Picture: Two Types of Deadlines
Freelancers have two kinds of tax dates:
- Payment deadlines. When you must send money to the IRS during the year (quarterly estimated taxes).
- Filing deadlines. When you must submit your tax return.
They are not the same thing. Even if you get more time to file, you generally still need to pay by the original due date.
Your Freelance Tax Calendar (2026–2027)
Sept. 15, 2026 — 3rd estimated tax payment for 2026 (already passed; pay as soon as possible if you missed it)
Dec. 31, 2026 — Last day for most year-end moves: paying business expenses, opening certain retirement plans, and similar
Jan. 15, 2027 — 4th estimated tax payment for 2026
Feb. 1, 2027 — Clients generally must send you Form 1099-NEC (Jan. 31 falls on a Sunday)
Apr. 15, 2027 — 2026 tax return due, and the 1st estimated payment for 2027

Sept. 15, 2027 — 3rd estimated tax payment for 2027
Oct. 15, 2027 — Extended deadline to file your 2026 return, if you requested an extension
The January 2027 dates follow the usual IRS pattern, but confirm them on the IRS website closer to the date, since the agency can announce changes.
Quarterly Estimated Tax Payments
Because no tax is withheld from your client payments, the IRS expects you to pay during the year using Form 1040-ES. Payments are due four times a year, but the periods are not equal quarters. That’s why the dates feel uneven: April 15, June 15, September 15, and January 15.
Key points to remember:
- You generally need to make estimated payments if you expect to owe $1,000 or more in federal tax for the year. Confirm the current threshold at the IRS estimated taxes page.
- You can avoid an underpayment penalty by meeting a «safe harbor,» which is based on a percentage of this year’s or last year’s tax. The percentages depend on your income.
- If a deadline falls on a weekend or holiday, it moves to the next business day.
- Many states with an income tax have their own estimated payment dates, which are often similar but not always identical. Check your state tax agency.

January: Tax Forms Start Arriving
Clients who paid you enough during the year must generally send Form 1099-NEC. The standard due date is January 31, but in 2027 that falls on a Sunday, so it moves to Monday, February 1.
Some things to keep in mind:
- You may also receive Form 1099-K from payment platforms and marketplaces.
- Reporting thresholds have been changing in recent years. Don’t assume you won’t get a form, and report all your income whether or not you receive one.
- If you work with many clients, see our guide on how to file taxes with multiple 1099s.
April 15: Filing Day and More
April 15, 2027 is the deadline to file your 2026 federal return (Schedule C and Schedule SE for most freelancers) and to pay any tax you still owe.
It is also the day:
- Your first estimated payment for 2027 is due.
- You can make last-minute IRA and HSA contributions for 2026.
That’s a lot in one day, so plan ahead and don’t leave payments to the last hour.
Need More Time? The October Extension
If you can’t finish your return by April, you can request an automatic extension using Form 4868, which moves your filing deadline to October 15, 2027.
An extension to file is not an extension to pay. If you owe tax, you should still estimate it and pay by April 15 to limit penalties and interest.
Retirement Contribution Deadlines
Retirement deadlines are different from tax-filing deadlines, and they depend on the account:
- IRA (traditional or Roth): by the April filing deadline, with no extension.
- SEP IRA: generally by your tax filing deadline, including extensions.
- Solo 401(k): employee contributions generally need to be set up by year-end, while employer contributions may be made by the filing deadline. Rules can vary by plan.
For more detail, read SEP IRA vs. Solo 401(k) and How to Open a SEP IRA. Contribution limits are published each year on the IRS retirement plans page.
Health Insurance Dates Also Matter
If you buy coverage through the Health Insurance Marketplace, there’s a separate open enrollment period each fall. These dates have been changing, so check HealthCare.gov for the current window instead of relying on old information. Missing it may mean waiting a year unless you qualify for a special enrollment period.
Simple Tips to Stay on Schedule
- Add every date to your calendar with a reminder one week and one day before.
- Set up a tax savings account. Move a set percentage of every payment into it right away.
- Pay online. IRS Direct Pay and your IRS online account make quarterly payments quick.
- Keep records of each payment. You’ll need the amounts when you file.
- Use a bookkeeping system so you always know your profit. Our guide to a simple bookkeeping system is a good start.

Frequently Asked Questions
What if I miss an estimated tax deadline?
Pay as soon as you can. The IRS generally charges interest and a penalty based on how much was underpaid and for how long, so paying late is better than not paying.
Do I have to pay quarterly if I also have a job?
Not always. If your job withholding covers enough of your total tax, you may not need estimated payments. You can also adjust your W-4 at work.
Are state deadlines the same as federal ones?
Often they’re similar, but not always. Check your state’s tax agency.
Is the filing deadline ever different?
Yes. Natural disasters can trigger postponements for affected areas, and weekends and holidays shift dates. Check IRS.gov for announcements.
Does an extension give me more time to pay?
No. It only extends the time to file. Payment is still generally due in April.
Final Thoughts
Taxes are easier when you know what’s coming. Save this calendar, put each date in your phone, and treat estimated payments like a regular business expense. A few reminders can save you penalties and a lot of stress.
