No. If you did not receive any OR pension income until after you moved to WA, then you will not need to include this OR pension on your OR part-year resident state income tax return. This is due to the fact that a federal law prohibits any state from
taxing pension income of non-residents, even if the pension was earned within
the state.
You will just need to include your OR-source wages only on your OR part-year resident state income tax return.
