Tax Day 2027: Thursday, April 15, Plus a Live Countdown

The tax deadline 2027 is Thursday, April 15, the due date for 2026 federal income tax returns. It lands on a Thursday. That date also covers extension requests, 2026 individual retirement account (IRA) and health savings account (HSA) contributions and the first estimated tax payment for 2027. The rest of the year’s deadlines follow the Internal Revenue Service’s (IRS) usual pattern, with a few moved by weekends and holidays. Here is every 2027 federal deadline for individuals and small businesses.

Countdown to the 2027 tax deadline

The clock counts to midnight at the end of Thursday, April 15, 2027 in your own time zone. Returns filed electronically are on time if submitted by then; a paper return is on time if postmarked by that date. Without JavaScript, use the table below.

2027 tax deadlines for individuals

Date	Day	What is due
Jan. 15, 2027	Friday	Fourth-quarter 2026 estimated tax payment (Form 1040-ES)
April 15, 2027	Thursday	2026 Form 1040; Form 4868 extension; 2026 IRA and HSA contributions; first-quarter 2027 estimate; Report of Foreign Bank and Financial Accounts (FBAR) on FinCEN Form 114
June 15, 2027	Tuesday	Second-quarter 2027 estimated tax
Sept. 15, 2027	Wednesday	Third-quarter 2027 estimated tax
Oct. 15, 2027	Friday	Extended 2026 Form 1040; FBAR automatic extension
Jan. 18, 2028	Tuesday	Fourth-quarter 2027 estimated tax

An extension gives more time to file, not to pay. Tax owed for 2026 is due April 15, and interest and penalties run on any unpaid balance after that.

Deadlines for employers and small businesses

Date	Day	What is due
Feb. 1, 2027	Monday	Forms W-2 to employees and the Social Security Administration; Form 1099-NEC to recipients and the IRS; most other 1099 recipient copies; Form 940; fourth-quarter 2026 Form 941
Feb. 16, 2027	Tuesday	Recipient copies of Forms 1099-B and 1099-S, and 1099-MISC with amounts in box 8 or 10
March 1, 2027	Monday	Paper Forms 1099 and 1096 to the IRS
March 15, 2027	Monday	Partnership (Form 1065) and S corporation (Form 1120-S) returns or extensions; Schedules K-1

Oct. 15, 2027	Friday	Extended Form 1120
Nov. 1, 2027	Monday	Third-quarter Form 941

Employers that deposited all of a quarter’s taxes on time get 10 extra days to file Form 941, and the same applies to Form 940 for the year.

Why some dates move

Federal law, 26 U.S.C. 7503, says that when a tax deadline falls on a Saturday, Sunday or legal holiday, it moves to the next business day. In 2027 that rule shifts five deadlines:

• Jan. 31 is a Sunday, so W-2s, 1099-NECs and fourth-quarter Form 941 are due Monday, Feb. 1.
• Feb. 15 is Presidents’ Day, so the 1099-B and 1099-S statements move to Tuesday, Feb. 16.
• Feb. 28 is a Sunday, so paper information returns are due Monday, March 1.
• July 31 is a Saturday and Oct. 31 a Sunday, so the second- and third-quarter Form 941 dates move to Aug. 2 and Nov. 1.
• Jan. 15, 2028 is a Saturday and Jan. 17 is Martin Luther King Jr. Day, so the last 2027 estimate is due Tuesday, Jan. 18, 2028.

Washington, D.C.’s Emancipation Day can push Tax Day when April 15 falls on a weekend or the holiday is observed on April 15 itself. That does not happen in 2027: the holiday falls on Friday, April 16, after the deadline. See our list of federal holidays in 2027 for the other days that can shift a deadline.

What the IRS has released and what is still pending

On Nov. 5, 2026, the IRS released the tax year 2027 inflation adjustments in news release IR-2026-133 and Rev. Proc. 2026-35. The release says the adjustments “generally apply to tax returns filed in 2028,” so the return due April 15, 2027 still uses the 2026 figures: a $16,100 standard deduction for single filers, $24,150 for heads of household and $32,200 for married couples filing jointly (Rev. Proc. 2025-32). For 2027, the standard deduction is $16,600 for single filers and married couples filing separately, $24,925 for heads of household and $33,200 for married couples filing jointly, up $1,000 from 2026. The top rate stays 37%, for single income over $661,375 and married filing jointly over $793,650. See the 2027 tax brackets and contribution limits for the full figures.

Two items are still pending as of Nov. 6, 2026:

• The 2027 401(k) and IRA contribution limits. The IRS announces them in a separate fall notice. The 2026 limits came out on Nov. 13, 2025.
• The start of filing season. The date the 2027 filing season opens is not yet announced.

We will update this story when the IRS publishes both.

Planning the year

Many people who pay estimated tax are self-employed or have income without withholding, such as investment gains or rental income. The payments are not evenly spaced. There are three months from the January payment to April, two from April to June, three from June to September and four from September to January. Set a reminder a week ahead of each one.

Social Security recipients can match the payment calendar to the 2027 Social Security payment dates. Businesses on a non-calendar fiscal year should check our fiscal year calendar guide, since their return dates shift with the year-end. Copy the deadlines onto a 2027 printable yearly calendar or the January and April monthly pages, or print the one-page tax calendar below. Confirm the dates in the 2027 edition of IRS Publication 509 once the agency issues it.
