We are both dual US/UK citizens and moved to England last May. I recently completed my US Federal and Louisiana State tax returns using TurboTax. The return was reasonably lengthy with qualified and non qualified dividends, capital gains, an annuity cashed in, Roth conversions, a qualified US pension, a non-qualified US pension, a UK pension, and 2 Foreign Tax credit forms (1116).
The Louisiana return was very simple as usual with only the W2 from a Louisiana company to report and claim back tax on, and when I completed it a few weeks ago TT said that overseas residents could not efile so I mailed a return, and even though I gave my US bank details they mailed out a refund check.
However, when it came to the Federal return I was able to efile and the return was accepted a day later
