How allocate unearned income for two states with partial year for each?

[edselby]

You suggest divide total by 12 and multiply by the number of months I lived in each state.  I moved in the middle of a month.  Do the states let me do whatever I want here, or do I need to calculate the percentage of the year that I resided in each state?  How fussy are the states going to be about this?

Yes - Divide the unearned income (like interest and dividends) by 12 and multiply by the number of months you lived in each state. 

Let's say you had $900 in interest income for the year.  Dividing by 12 gives you $75/month.

If you moved in the middle of July, you spent 6.5 months in the first state and 5.5 months in the new states. 

• Interest allocated to first state:  6.5 x 75 = 487.50
• Interest allocated to second state:  5.5 x 75 = 412.50
