Risk Radar
Scan points- 1A single typo in your SSN can invalidate the entire extension request.
- 2Under‑estimating tax due, leading to interest and penalties
- 3Missing the April deadline, causing automatic late‑filing penalties
- 4Incorrect Social Security number or name mismatch
- 5Sending the form to the wrong IRS address
Plain English
If you can’t get your personal tax return done by the April deadline, you can file Form 4868 to get extra time. The extension only delays filing, not payment of any tax you owe.
Submission Date
- Filing date: It must be filed by the original filing deadline (usually April 15) for the tax year you are extending.
- Preparation window: collect IDs, supporting records, and signatures in advance.
- Final review: verify names, dates, and required fields before submission.
