"His New York non-resident return will report only the income earned in New York."
Do you mean he doesn't need to report his Ohio income on NY form 203? Instruction says federal column of line 1 on form 203 should equal the amount on the federal 1040.
Shouldn't he report both his NY income and Ohio income in Federal column on page 1 of form 203, then on page 2, first total NY tax on his total income is calculated, then that amount is multiplied by factor (ratio) of NY income divided by total income to get his final NY tax?
Thanks.
