State tax filing

Hi @feiwenw66563. The New York nonresident income tax form IT-203, will include all federal income in column A (Federal amount) and NY income in column B (New York state amount).

NY will compute a base tax as if all income for the year was earned in NY. That base tax is then multiplied by NY income ÷ total income to come up with the NY tax. For example, if your total income is $25,000 and $12,500 was earned in NY, then your tax rate is based on $25,000 but your actual tax is 50% of the tax on $25,000.
