Lots of people make this mistake every year. Filing an amended return when you shouldn’t can confuse the
IRS and make your situation even more complicated.
Here are the most common situations when you should NOT file an amended return – and exactly what to do
1. You got an IRS CP2000 notice (also called an underreporter inquiry).
If you got a notice about “underreported income” from the IRS, don’t file amended return. In fact, filing
an amended return confuses the IRS. That’s because the IRS is expecting a response to the notice, rather
than a new return that goes to a completely separate IRS unit. Basically, filing an amended return when you
get a CP2000 notice slows down the process and creates new complications.

2. You got an IRS audit notice.
In this case, you need to respond to the notice with the information and documents the IRS requested. You

If you forgot to attach an information statement or schedule to your return, no big deal. The IRS will

4. The IRS rejected your e-filed original return.
The first thing to do is verify all items on your return (names, birthdates, Social Security Numbers) and

like when two people claim the same dependent.

5. You made a calculation error on your return.
If your return has an arithmetic error, there’s no need to file an amended return. The IRS will usually
correct it and send you a notice letting you know.
But — you or your tax professional should confirm that the IRS changes are correct.
6. The IRS prepared a return for you.
If you have back tax returns, the IRS can eventually prepare a return for you (called a
substitute for return
The IRS prepares the return based on the information it has from your employer, bank, and other payers, and
the substitute return won’t have any credits or deductions in your favor.
In this case, don’t file an amended return. Instead, you can file a Form 1040 to replace the substitute for
return, to use a better filing status and any exemptions or credits you may be entitled to.
