You can start filing taxes for your 2026 return on the IRS’s opening day, which it announces each January; the last three seasons opened between January 26 and January 29. Tax software will take your return earlier and hold it until then. Your employer has until February 1, 2027 to send your wage statement.

Most e-filed refunds arrive in under three weeks. If you claim the Earned Income Tax Credit or the Additional Child Tax Credit, two credits for working families, the law holds your whole refund until mid-February.

When does the IRS start accepting tax returns in 2027?

The IRS hasn’t announced the 2027 opening day yet; it names the day in a January news release, as it did on January 8, 2026 (IR-2026-02). In each of the last three seasons, it started accepting returns on a Monday between January 26 and January 29. The IRS does not begin accepting returns until opening day (IR-2025-08).

This post sits inside our plain-English guide to filing your taxes: filing status, a first return, a missing W-2.

In 2024 the IRS opened on January 29 (IR-2024-04). In 2025 it opened on January 27 (IR-2025-18).

In 2026 it opened on January 26, with e-file starting at 9 a.m. Eastern (IR-2026-12; IRS e-file status page).

The season is named for the year you file in, not the year you earned the money. The 2026 season took 2025 returns; the 2027 season takes your 2026 return. I wouldn’t plan around a specific January date for 2027.

These are the dates that matter for your 2026 return.

Can I file before the IRS opens?

Yes. You can get the return ready and submit it through software before opening day. Most software companies accept electronic submissions and hold them until the IRS is ready to begin processing (IR-2024-04, January 8, 2024). You can also work on the return with a tax professional before opening day.

For the 2026 season, IRS Free File began accepting returns from qualified taxpayers on January 9, 2026, more than two weeks before the season opened (IR-2026-02).

When will my W-2 and 1099s arrive?

Your Form W-2, the wage statement your employer sends, is due to you by February 1, 2027 (2026 General Instructions for Forms W-2 and W-3). The law gives employers until January 31 to send it (IRC §6051(a)), and because January 31, 2027 falls on a Sunday, the next business day counts (§7503).

Most 1099s follow the same January 31 rule, so they land on February 1, 2027 too. That includes Form 1099-NEC, the form clients and gig platforms send for nonemployee pay (Instructions for Forms 1099-MISC and 1099-NEC).

Form 1099-B, the brokerage statement for sales of stocks and funds, is the common exception. It is due to recipients by February 15, or the next business day when that date falls on a weekend or legal holiday (Publication 1099).

If you own part of a partnership or S corporation, your Schedule K-1, the statement showing your share of the business’s income, follows the business’s own return, which is due March 15 (IRC §6072(b)). A partnership that takes its automatic six-month extension can send K-1s as late as September 15, 2027 (Treas. Reg. §1.6031(b)-1T(b)).

An S corporation sends K-1s on or before the day it files its return (IRC §6037(b)). I tell owners who expect a K-1 not to plan on filing in February. If you own an LLC, S corp or partnership interest, our K-1 guide, written for owners like you, explains the form itself.

If a form is missing after the February 1, 2027 due date, contact the employer or payer first. If you’ve asked your employer and the W-2 still hasn’t come by the end of February, call the IRS at 800-829-1040. If it still doesn’t arrive in time, Form 4852 is the substitute on which you estimate your wages and the tax withheld (Topic no. 154). If the real form shows up later with different numbers, you fix the return with Form 1040-X, the amended return.

My advice is simpler. Wait until everything arrives. The IRS tells filers to report all taxable income and to wait to file until they have received all of their income documents (IR-2025-18, January 27, 2025).

When will I get my refund?

The IRS issues most refunds in fewer than 21 days (IR-2026-12, January 26, 2026). An e-filed return takes about 3 weeks from the date you e-filed. A mailed return takes 6 or more weeks from the date the IRS receives it (IRS Refunds page). Some returns take longer when they need corrections or further review.

Two things speed the money up. File electronically and choose direct deposit, which the IRS calls the fastest way to receive a refund. And have your routing and account numbers ready. The IRS began phasing out paper refund checks on September 30, 2025 under Executive Order 14247, so most taxpayers now need a bank account to receive a refund (IR-2026-12).

You can track the money with Where’s My Refund, the IRS refund tracker. Status is generally available about 24 hours after e-filing a current-year return, or four weeks after filing a paper return (IR-2026-02).

A refund can also be reduced to pay prior taxes owed, past-due child support, federal agency nontax debt, or state income tax (IRS Refunds page). I wouldn’t spend a refund before it lands; the IRS itself warns not to count on one by a certain date for major purchases or bills (IR-2025-18).

When is the deadline to file 2026 taxes?

The deadline to file your 2026 federal return is Thursday, April 15, 2027 (IRC §6072(a); Publication 17). The statute sets the 15th day of April for calendar-year filers. April 15, 2027 falls on a Thursday, so no weekend rule moves it (§7503).

If you need more time, an automatic six-month extension is granted by regulation when you file Form 4868 by the due date (Treas. Reg. §1.6081-4(a)). An extension is more time to file, not more time to pay, so interest runs on any tax unpaid after April 15, 2027 (Topic no. 301).

One January date matters if you had 1099 or other untaxed income in 2026. Your fourth estimated payment is due January 15, 2027. You can skip it if you file your 2026 return and pay the entire balance by February 1, 2027 (2026 Form 1040-ES). Our first-time quarterly-tax walkthrough was written for 1099 and gig workers, and its January 15 rule applies to anyone with untaxed income.

What happens if I file before every form arrives?

The IRS gets a copy of every W-2 and 1099, so income you leave off comes back as a tax bill that can carry a 20% penalty on the underpaid tax, the accuracy-related penalty (IRC §6662). A form that got lost in the mail still reached the IRS. You must report all taxable income even if you don’t receive the form (IR-2026-02).

In Sweeney v. Commissioner (T.C. Summary Opinion 2016-32), a long-time insurance agent and his wife lost their home in 2011 and moved three times the next year. They testified that because of the moves, they had not received all of the Forms 1099-MISC reporting his commissions.

Four payers had reported the agent’s 2012 commissions to the IRS on Forms 1099-MISC. The forms totaled $35,703. The couple’s return reported $4,207 of gross receipts from insurance sales. The IRS matched the forms, assessed tax on the $31,496 difference, and added a 20% accuracy-related penalty. The Tax Court upheld the penalty. Not receiving the forms, the court wrote, “is not a defense,” because taxpayers are obligated to report taxable income whether or not a form arrives.

The court added that if he had kept accurate records of his business income, the missing forms would not have mattered. Our receipts guide is aimed at self-employed owners; its record-keeping habits work for anyone paid on a 1099.

I’d rather file a few weeks later with every form than on opening day with one missing. If you’d rather hand that matching to someone else, our tax preparation team does it before your return goes out.

Why is my refund held until mid-February if I claim the EITC or ACTC?

No refund on a 2026 return that claims the Earned Income Tax Credit or the Additional Child Tax Credit can be paid before February 15, 2027 (IRC §6402(m)). Those are credits for working families that can be paid out as a refund. The hold covers your entire refund, not just the part related to the credit (IRS refund-timing page).

The rule comes from the Protecting Americans from Tax Hikes (PATH) Act, and the IRS says the refunds are held to prevent fraud (IR-2025-18; IRS Refunds page). One TurboTax Community poster, after noting that EITC refunds don’t go out until mid-February, asked in February 2025:

“does anyone know if they process those returns earlier then mid -Feb”

The law sets the payment date, not the processing date. For the 2026 season, the IRS said Where’s My Refund would show projected deposit dates for most early EITC/ACTC filers by February 21, 2026. It expected most of those refunds in bank accounts by March 2, 2026, for direct-deposit filers with no other issues (IR-2026-12). The IRS updates Where’s My Refund once a day, usually overnight (IRS refund-timing page).

The season before, the expected deposit date was March 3, 2025 (IR-2025-18). The 2027 target will come with the IRS’s January announcement. I’d start checking Where’s My Refund once the date in that January release has passed.

Does California accept returns before the IRS does?

Yes. For the 2026 season, California’s first day to accept e-filed returns was January 2, 2026, more than three weeks before the IRS opened on January 26, 2026. After that first day, FTB keeps taking e-filed returns all year; it says it processes them continuously throughout the year (FTB e-file calendars).

The Franchise Tax Board launched its 2026 season on January 7, 2026, and most Californians can e-file the state return free through CalFile (FTB, January 7, 2026).

FTB has not posted its 2026-return due dates yet. For 2025 returns, the California due date was April 15, 2026, and the state granted an automatic extension to October 15, 2026 to file — no application required — though payment was still due in April (FTB due dates). State refunds run up to 3 weeks for e-filed returns and up to 3 months for paper (FTB Where’s My Refund).
