Income tax deadline 2024: A beginner’s guide
If you’re trying to figure out when you must file your income tax return, here’s a clear, beginner-friendly overview. Note: tax deadlines vary by country and by level (federal vs state/local). The details below focus on the United States federal income tax deadlines for individuals.
---
Quick answer (US)
- For the 2023 tax year, the federal filing deadline was April 15, 2024.
- For the 2024 tax year, the federal filing deadline is typically April 15, 2025 (unless that date falls on a weekend or holiday, in which case the deadline moves to the next business day).
- If you file an extension, you can get extra time to file until October 15, 2025. An extension to file is not an extension to pay any tax you owe.

If you’re in the United States
Key dates to remember
- Tax year 2023 return due: April 15, 2024
- Tax year 2024 return due: April 15, 2025 (subject to weekend/holiday adjustments)
- Extension to file: October 15, 2025 (requires filing Form 4868 by the April due date)
- Estimated tax payments (if you owe): typically due quarterly (for example, April 15, June 15, September 15 of the year, and January 15 of the following year)
- E-filing is available and recommended for faster processing
What happens if you owe taxes
- Pay as much as you can by the due date to minimize penalties and interest.
- If you can’t pay the full amount by the due date, you should still file on time and consider setting up a payment plan with the IRS.
- Extension to file does not postpone your tax liability. You’re still responsible for any tax owed, plus interest and penalties on any unpaid balance.
How to obtain an extension
- Use IRS Form 4868 (automatic extension to file).
- You can file electronically or by mail.
- You must estimate and pay at least 90% of your current year’s tax or 100% of your prior year’s tax (110% if your adjusted gross income was above a certain threshold) to avoid penalties on the amount you owe.
Quick tips for beginners
- Gather your documents: W-2s, 1099s, and any other income or expense records.
- Decide your filing status (single, married filing jointly, etc.).
- Choose a filing method: IRS Free File, commercial tax software, or a tax professional.
- Consider electronic filing for faster processing and easier tracking.
- Don’t forget credits and deductions you may qualify for (e.g., standard deduction vs. itemized deductions, education credits, earned income credit, etc.).

State and local deadlines
- Many U.S. states have their own income tax deadlines, which can be the same as or different from the federal deadline.
- Some states start accepting returns earlier or later and may require separate extensions.
- Check your state's Department of Revenue or tax authority website for the exact date and any special rules.

Important caveats and exceptions
- If the tax deadline falls on a weekend or a holiday (including Emancipation Day in Washington, DC, which can affect the federal deadline), the due date moves to the next business day.
- If you’re self-employed or have complex situations (e.g., multiple states, amended returns), consider seeking guidance from a tax professional.

What if you’re not in the United States?
Tax deadlines vary widely by country (and within countries by region or state). If you’re asking about a different country:
- Check the official tax authority for that country (e.g., HMRC in the UK, Canada Revenue Agency in Canada, etc.).
- Look for the specific year (2024) deadline and any extensions or quarterly payment requirements.
- If you want, tell me your country, and I can tailor the deadline information accordingly.
