I forgot my tax id number. How do I get it?

Look through all your past tax papers. It should be on those forms or contact your accountant

Hi, tudavis1016!

Since your question wasn't so much about a small business but more about taxes, I re-titled and moved your question to this topic area.

If there's more to it as to forgetting your tax ID number, please do indicate that on this thread.

Thanks!

You can also contact either the IRS or the state tax department; they both will have it on record.
