ND HB1174

Creates an individual income tax deduction for social security benefits for taxpayers with federal adjusted gross income of $50,000 or less (or $100,000 or less if married filing jointly), reduced by the amount of social security benefits included in federal adjusted gross income.

Amends the homestead tax credit definition of "income" to exclude social security benefits from income calculations, allowing applicants to reduce their counted income by any social security benefits received.

Establishes a marriage penalty credit of up to $300 per couple filing jointly, with the tax commissioner adjusting the maximum amount annually based on rate schedule adjustments.

Defines "qualifying income" for the marriage penalty credit to include earned income, retirement pension/annuity income, and social security benefits to the extent included in North Dakota taxable income.

Takes effect for taxable years beginning after December 31, 2018.
