IRS mailing addresses by form

The IRS uses different addresses for different forms, for different states, and often for a return with a payment and a return without one. Each page below copies the table from irs.gov for one form and shows the date we read it.

The last column matters. Most paper returns must be signed by hand in ink. Certisent prints what you upload, so a signature would arrive as a printed image and the IRS can treat the return as unsigned. For those forms we show the address and you mail the signed original yourself.

Each page explains its signature rule and links the IRS source it comes from. If the IRS page and ours ever differ, the IRS page is right.
