amended trust tax return how many years
You indicate the year of the tax return you're amending at the top of Form 1040X. For amended returns, the IRS sets a deadline of three years from the date the original tax return was due.For example, if the due date of the return was April 15, 2010, you have until April 15, 2013, to file a Form 1040X for 2009.f it does not have that information, you are well advised to file an amended return as soon as possible and pay the additional tax before the due date (normally April 15 following the tax year, for individuals).
