Once you set up a PIN you can continue to use it from one year to the next, or you can establish a new PIN.
When you set up your PIN, you will need to enter your date of birth and your Adjusted Gross Income (AGI) from last year’s tax return, as it was originally filed. Since this data is used to identify you, there are some specific rules to follow in reporting last year’s AGI.
If the IRS corrected your return, or you later submitted an amended return, the AGI you need for purposes of the self-select PIN is the AGI on your original return for last year, even if it was incorrect.
If this is the first time you are filing, you should enter zero ("0") for your AGI, rather than leave it blank.
If you changed from filing single last year to married filing jointly this year, each taxpayer should use their individual original AGI from their respective returns from last year.
If you changed from married filing jointly to married filing separately or single this year, each taxpayer should use the same original full AGI from last year’s joint return.
If you filed a joint return with a different spouse last year, you should use the original full AGI from the joint return filed with your ex-spouse last year.
If you filed a joint return last year but only one spouse had all the income, both spouses should use the same original full AGI from the joint return filed last year.
