Yes, that is correct: I have paid income tax to NYS on my job located in NYS, and TT has filled out the 'MA Tax Credit Worksheet' to reduce my MA state tax (via a credit for the NY state tax I have already paid).
On this worksheet, I'm wondering why TT appears to have calculated the '5% income tax' (line 4) from Form 1-line 19 (5% Income After Exemptions) and not Form 1-Line 21 or 22 (Total Taxable 5% Income and the corresponding Tax on 5% Income). Is it correct to use Line 19 and not Line 21?
