Dual State Tax Filing Assistance

[jeterschak]

I have to file state tax in Missouri but have non resident income in Washington State who does not have a state income tax.  Turbo Tax does not directly support this other than completing some of forms manually.  I can't see where to incorporate my Educational Contributions (529 plans) when doing it manually.  Can you recommend where I can get assistance to prepare my Missouri State Tax based on info from Federal Tax which I have complete and what income applies to Washington?

A Missouri resident is taxed on income earned everywhere, so your combined Missouri and Washington state income is taxable to MO. States allow a credit for state income tax paid to another state, but since WA has no income tax, there is no credit.

File a full-year Missouri return. You can enter your 529 contribution under Savings for Tuition Programs.
