This is my first year apportioning income. I am apportioning my income between NH and MA. I worked 248 days total. 95 days in MA and 148 days in NH. So 60.9% of my days were worked in NH. My Social Security deductions were $4,261. When entering Non-Massachusetts Portion of Deductions so I simply calculate 60.9% of what I paid for social security, so $2,594.95?
