Have a Tax Question? Ask a Tax Expert
I am unaware of a way to get a copy of the document online. In my experience, these installment agreement requests take about 90 days to process. If it takes longer, I file it again.
You can still make payments. They are expecting you to make the payments even without a letter. You can mail in a check with the tax year in the memo. Include a letter requesting the document. This will be more effective than a phone call.
