State Income Tax Credit for Taxes Paid to Another State

You will need to complete Schedule OJC within the Massachusetts Form 1 tax module of TurboTax personal version. 

The following assumes that your words where you say "The partnership pays the state income tax on behalf of all the partner" means that the payment so made is reported to you as income (either explicitly or within the total amount of income, however the partnership reports).

This can be done by two different methods. 

1. Please see attached pages showing the steps within the MA Form 1 module interview.  The last page is the Schedule OJC that is generated and the line 9 Credit amount, zero or non-zero, will depend on your circumstances and the amounts of other Massachusetts income and  taxes paid.
2. Instead, if you really feel you know what you are doing, you can complete  the remainder of MA Form 1 Interview and then in upper right
   1. click "Forms" to go to Forms View, 
   2. Click Open Form
   3. Enter in Search line "OJC" 
   4. This will disclose the Schedule OJC and you can make entries directly.
