When Does Tax Season Start? 2026 IRS Filing Dates

Here’s what you need to know about timing for the 2025 tax year filings (filed in early 2026).

Personal records to gather

- IRA/401(k) contribution records
- Previous year’s tax return (for reference)
- Bank account info for direct deposit
When can you expect your refund?
The IRS typically processes refunds within 21 days of accepting an e-filed return. Direct deposit is faster than paper check (usually 5-7 days quicker).
Standard timeline
| If accepted by | Direct deposit by | Paper check by |
|---|---|---|
| Jan 31 | Feb 21 | Feb 28 |
| Feb 7 | Feb 28 | Mar 7 |
| Feb 14 | Mar 7 | Mar 14 |
| Mar 14 | Apr 4 | Apr 11 |
EITC/ACTC delays
Under the PATH Act, the IRS cannot issue refunds claiming Earned Income Tax Credit (EITC) or Additional Child Tax Credit (ACTC) before mid-February. Even if you file January 27, your refund won’t arrive until February 27 or later.
This delay applies to the ENTIRE refund, not just the credit portion. Plan accordingly if you depend on early-year cash flow.
Status tracking
Check “Where’s My Refund?” at irs.gov/refunds or via IRS2Go app. Status updates daily (usually overnight). You’ll need:
- Your SSN
- Filing status
- Exact refund amount
How to file early
File the first week the IRS opens (late January 2026) by:
- Gathering all documents in January
- Using tax software that supports early-bird filing (TurboTax, H&R Block, FreeTaxUSA, TaxAct)
- Submitting electronically (e-file is much faster than paper)
- Choosing direct deposit (no waiting for paper checks)
Tax software opens for prep in mid-December but actual filing waits for IRS acceptance.
Why file early?
- Faster refund — money in your pocket weeks sooner
- Identity theft protection — fraudsters can’t file fake returns with your SSN if you’ve already filed
- Less stress — done in January vs. last-minute April panic
- More time to address problems — if something’s wrong, you have months to fix vs. days
Why file late (October extension)?
- Waiting on K-1s — partnerships often issue K-1s in March-September, delaying your filing
- Complex situations — international income, business closure, divorce, inherited assets
- Maximum IRA contribution time — extension preserves traditional IRA contribution flexibility… wait, no, IRA deadline is still April 15 even with extension
- Procrastination — common but expensive (late fees if you owe)
What if you can’t pay by April 15?
File anyway by April 15 — late filing penalty (5% per month) is MUCH worse than late payment penalty (0.5% per month).
Options if you can’t pay:
- Pay what you can — reduces interest charges
- Installment agreement (Form 9465) — IRS will accept monthly payment plans
- Offer in Compromise (rare) — if you can prove inability to pay full amount
- Currently Not Collectible status — temporary hardship deferral
What is the PATH Act?
The Protecting Americans from Tax Hikes Act (2015) requires the IRS to hold all refunds for EITC and ACTC claimers until February 15. This anti-fraud measure delays roughly 25 million low-to-middle-income filers each year. Don’t expect EITC refunds before mid-February.
When does tax season “end”?
Officially: April 15 (or the next business day if April 15 falls on a weekend/holiday).
Practically:
- April 15 for most filers
- October 15 for extension filers
- No deadline if you owe nothing — but you forfeit your refund 3 years later if you don’t file
Estimated tax payment dates (for self-employed)
If you have self-employment or other untaxed income, you owe quarterly estimated taxes:
| Quarter | Period covered | Due date |
|---|---|---|
| Q1 2026 | Jan-Mar 2026 | April 15, 2026 |
| Q2 2026 | Apr-May 2026 | June 16, 2026 |
| Q3 2026 | Jun-Aug 2026 | September 15, 2026 |
| Q4 2026 | Sep-Dec 2026 | January 15, 2027 |
Use Form 1040-ES to estimate and submit payments. Failure to pay quarterly can trigger underpayment penalties.
Frequently asked questions
Q: Can I file taxes before I get my W-2? A: You shouldn’t. Wait until you receive your W-2 (typically late January). Filing without it requires reconstructing wage info, which often leads to errors and audits.
Q: What if I forget to file by April 15? A: File ASAP. Penalties: 5% per month for late filing (max 25%) + 0.5% per month for late payment + interest. If you’ll owe nothing, no penalty — but you forfeit refund after 3 years.
Q: Can I file my taxes in December? A: No. IRS doesn’t accept returns until late January (tax software may let you prepare in mid-December but holds the actual filing). The earliest realistic e-file date is around January 27.
Q: When are state tax returns due? A: Most states match the federal April 15 deadline. Exceptions: some states have different deadlines (e.g., Iowa is April 30). Check your specific state.
Q: Should I do my taxes myself or hire someone? A: DIY (TurboTax, FreeTaxUSA, H&R Block) works for ~80% of US filers with relatively simple returns. Hire a CPA or EA if you have: business income, multiple states, foreign income, K-1s, complex deductions, prior-year issues, or income over $250K.
