I received my federal tax i.d. number two years ago for a home based business that I ended up never starting. What should I do?

Hello, pheobe3!

I just moved your question from Home-Based Business over to this topic area so that it would be more likely to get answered by someone who really knows about tax issues. I hope that you don't mind. It will be more likely to be answered correctly and accurately over here.

Thanks!

You mean EIN-- Employer's Indentification Number. You don't need to do any thing.

To expand on MuKat's answer, just don't use it. You don't have to return it or inform the IRS that you aren't using it. As long as they receive no 1099s or returns, using that number, they don't care.

Agreed; after a number of years of inactivity, the IRS re-issues the EIN to another taxpayer who will use it.
