Foreign-earned Bank Interest on State tax return

[S_And_J 7]

Hi all!

 

So we're about to send off our state taxes but am having trouble finding information on whether we count interest earned on foreign bank accounts? We have already declared it on the federal return, but were really unsure how the whole 'part-year' resident thing works for states when you first move to the U.S half way through the year?

 

As an example: Say that I earned $50 of interest from my bank account in the UK in 2018. I then came to the US mid-way through the year and began residing in a U.S. State, so approx. $25 of the total amount was technically earned while I was in the U.S. state, but it was not from state sources. Do I include the $50 as a whole like I did with the federal return, or do I just include for the time that I was physically present within the state ($25) or do I not include it as state income at all as it was not actually earned from state sources?

 

Apologies if that's slightly confusing! Happy to provide clarity!

 

Thanks all!
