Updated for Tax Year 2014
The Internal Revenue Code puts a limit on the time in which you can claim a refund for the overpayment of tax. You have to file the claim within three years from the date you file the original tax return or, if you don’t file a return, within two years of the date you actually overpay the tax.
Can I claim tax refunds on unfiled returns?
Filing a complete tax return is the only way to make a valid refund claim. If the refund relates to a tax year when you don’t file a return, you have to file an original tax return within two years of paying the tax. The IRS starts the two-year period on the April 15 that immediately follows the relevant tax year.
How long do I have to claim refunds on amended returns?
The three-year period applies to taxpayers who file the original tax return on time but later discover an error that should have given them a lower tax liability for that year. To initiate a refund claim, you have to file an amended tax return. The three-year
period begins on April 15 in the year immediately following the close of the relevant tax year, not counting any extension of time to file the IRS grants you.
What if I miss the window for a tax refund because of a disability?
The IRS can suspend the limitation period during times when a physical or mental impairment renders you incapable of managing your personal financial affairs. To qualify, the impairment has to last or be expected to last for at least 12 consecutive months or potentially result in death. You have to provide the IRS with a written statement from your physician attesting to the seriousness of the impairment. The IRS will extend the standard limitation period by the amount of time you suffer from the impairment.
Can I still file a Tax refund if the IRS extends their assessment period past the due date?
The standard time limitation on claiming a tax refund does not apply if the IRS extends the assessment period for the relevant tax year. Generally, the IRS has three years from the time you actually file the tax return to examine it and assess additional taxes.
