I live in NY for the whole year and work for the first company in NY and the second company in NJ.
For example:
company 1 state tax: NY 5,000
company 2 state tax (2 W2s for the same company): NY box 16 is 12,000
NJ box 16 is 13,000
When I filed NY resident, 'Taxes Paid to Another State' asked about income taxed by New Jersey. The New York Salary shows 17,000 (=5,000 + 12,000). What number is 'Portion Taxed by New Jersey'? should it be 13,000 or 12,000? Thanks.
