My ex has back taxes up the arse (well, just $3-5K) and has asked for my social security number so he can file his taxes and pay the IRS. I always filed "married filing separately" because I had a proper tax-taking paycheck and he didn't. Am I responsible for his debt because we were married when he neglected to pay the taxes?

I'm guessing not. I paid taxes on what I earned and also on our property (wasn't in his name), so I feel like i'm in the clear, but who knows when the IRS gets involved.

Anyone?

I wouldn't give him your Social Security Number, though I doubt you are responsible for his tax debt if the IRS hasn't filed a claim against both of you. The only time you'd be responsible for his debt would be if you were both co-signers on a loan or jointly held a credit card.

don't give him that number.
call a lawyer not a music board.
seriously.

f dat

I'd listen to her.

Just chiming in with agreement...never give a social security number out...especially to an ex.

you are fine. dont give anyone anything ever. make it a policy.

Just give him the Social Security number.

But rearrange the numerals into a code like in The Wire Season One.

haha. making the world a better place, eh?

back taxes is an ugly phrase

not sure about taxes at all but most states have Family Expense statutes where certain debts incurred by one spouse can be collected from either, even after divorce. I do not believe taxes are included in those, but if he has any other debt you are worried about I would look at your state's statute.
