On Massachusetts Tax return what is "Non-Massachusetts Portion of deductions?

[Zbucklyo · Accepted solution]

I am going to correct the answer of [mention://64461373 [mention://64461373 @TurboTaxIrene]].  MA gives you a deduction (up to $2,000) for payments made into the social security system and medicare (or mandatory payments to state retirement systems) while you were working in MA.  I am assuming you are filing a MA part-year resident/non-resident tax return.  If you worked entirely in MA, the answer is zero.  If you worked partially in MA, you calculate the amount of social security and medicare taxes withheld not attributed to working in MA.

I paid 7960 for SS and 1973 for Medicare in MA and later 7960 SS and 2226 Medicare in NYState, what will be my Non-Massachusetts portion of deductions? Thank you.

Add up NYS social security and Medicare payments.  Double-check that you have gotten the full $2000 deduction by looking at Line 15 on MA Form 1 NR/PY.

It is the amount of the deductions you took that occurred while you do not live in Massachusetts.  An example would be the mortgage interest and real estate taxes on a property that you lived in while you were living in another state; or charitable contributions you made while in that other state.
