I do taxes for a friend of my son's who lives in Thailand. He owns a FL based S Corp but lives and works in Thailand. He has a Thai wife. When filing his income tax return his wife has no reason to have a ss# so do I file the taxpayer as single? The tax software indicates I can't leave blank or all zeros and electronically file. We have to file electronically since taxpayer is living overseas...can I override the ss# field and still efile on Proseries Basic?
