Taxes aren't a once-a-year thing when you're self-employed

If you work a regular W-2 job, taxes are easy to ignore most of the year — your employer withholds them from every check. But if you drive for a rideshare app, deliver groceries, or pick up any kind of 1099 work, the IRS expects you to pay as you go, not just once in April.

That means 2026 has more than one date circled on the calendar. Here's what's actually due, and when.

The main deadline: April 15, 2026

This year, April 15 is the deadline for taxpayers to file 2025 federal income tax returns. That's the date your 2025 return is due, along with any taxes you owe for that year.

If you can't finish your return in time, individual income tax returns are typically due April 15, unless the date falls on a weekend or holiday or you file Form 4868 seeking an extension until October 15. But here's the part people miss: if you file an extension by that date, your filing deadline moves to October 15, 2026, but any tax owed is still due April 15. An extension buys you time to file the paperwork — not time to pay.

The dates most gig workers forget: quarterly estimated taxes

This is the big difference between a 1099 job and a W-2 job. Independent contractors, gig workers, and self-employed people usually have to make quarterly estimated tax payments on pre-set dates throughout the year. (Exact dollar thresholds and rules can vary by individual situation, so this is general information, not personalized tax advice.)

For 2026, the schedule looks like this:

  • January 15, 2026 — Final estimated payment for 2025 income (October through December)

  • April 15, 2026 — First estimated payment for 2026 income (January through March)

  • June 15, 2026 — Second estimated payment for 2026 income (April through May)

  • September 15, 2026 — Third estimated payment for 2026 income (June through August)

  • January 15, 2027 — Fourth and final estimated payment for 2026 income (September through December)

The federal estimated tax payment deadlines for tax year 2025 are April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. Notice the periods aren't even three-month blocks — the June 15 payment covers income earned April 1 through May 31, only two months, so it arrives fast.

One thing worth knowing if you're scrambling to catch up: those who file their annual tax returns by January 31 do not have to pay estimated taxes by the January 15 deadline. If you'd rather just file your full return early than send in a fourth quarterly check, that's an option.

Who actually has to pay quarterly

Not everyone needs to bother with this schedule. Generally, if you expect to owe $1,000 or more in federal tax for the year after withholding and credits, you are required to make quarterly estimated payments — and this includes freelancers, gig workers, and 1099 contractors.

If you're doing gig work as a side hustle on top of a W-2 job, and your employer already withholds enough from your paycheck to cover both jobs, you may not owe anything extra — but this depends on your specific withholding and income, so it's worth checking with a tax professional or using an IRS estimator. If gig income is your main source of pay, quarterly payments are usually the expectation, not optional extra credit.

A few other dates worth knowing

  • February 2, 2026 — Employers must furnish W-2 forms to employees, and businesses must send 1099-NEC forms to independent contractors who earned $600 or more. This is when the gig apps you worked for should have your tax forms to you.

  • October 15, 2026 — If you filed for an extension, this is the final deadline to actually file your return. Remember: any money owed was still due back in April.

What happens if you're late

The consequences depend on whether you owe money. What happens if you file federal taxes late depends on whether you owe the IRS money — if you don't have a tax bill, there is no penalty for filing past the deadline. But if you do owe, late filing and late payment can both come with their own penalties and interest, and missed quarterly payments can trigger a separate underpayment penalty even if you eventually pay everything in full.

The simplest way to stay ahead of it

The pattern worth remembering: April, June, September, and January. Those four dates repeat every year for anyone with 1099 income, and missing one quietly adds up in penalties even if you're not far behind.

A lot of gig workers get tripped up not because they don't know taxes are coming, but because the money isn't set aside when the date arrives. Setting a reminder for each of these dates — and routing a percentage of every gig payout into a separate savings space as it comes in — makes the quarterly deadline a lot less stressful than scrambling for it at the last minute.
