UK Spouse Doesn't Have SSN!!!

This is the first year that April 15th have come and gone since my wife and I were married last summer -- my first marriage.  I'm still in the US and she is in the UK.  Normally, I file taxes even though I technically don't have to do so and never owe any taxes.  I use the TurboTax e-filing set-up because taxes hurt my brain. 

This year, I didn't file because when I put myself in the category of Married Filing Separately, my wife's Social Security number was required.  Of course, she doesn't HAVE a Social Security number! 

I didn't research it at the time since I really don't have to file taxes, and just let it go.  But for future reference, what should I have done if I had wanted or needed to file this year?  I had thought about getting a paper form and just writing in that she wasn't a US citizen, had no taxable income, and didn't live on US soil, but that was just the musings of a tax-strained brain...

You can't use the online form.  But on a paper form you write NRA (non-resident alien) in the ss# space.

If you had filed you would probably have gotten a $400 Making Work Pay credit for 2010. You might want to see if you can file late. The penalty for a late filing might be less than the credit you would get.

My DH used turbo tax this year to fill out his taxes. Obviously he couldnt use it to efile but he printed out the forms (which had been filled in by turbo tax) and wrote 'NRA' where it asked for my SSN he then signed it and sent it off - hope that helps!

Thank you all -- helpful answers as always!

Cheers & g'day!
