Subject line pretty much says it: I've lived outside the USA for 20 years now, but I am still a US citizen, so I still have to file a US tax return. I pay my installments to the IRS, and at the end I wind up either owing nothing to the IRS, or owing a small amount, or occasionally they owe me a small amount (my country of residence has a tax treaty with the US and I am mostly taxed here). Is there any reason why I can't use FreeTaxUSA to file my US return? Thanks!
