Income Tax - Subtraction Modification for Military Retirement Income - Individuals Under the Age of 55

HB 857 modifies Maryland's income tax rules to reduce the tax deduction for military retirement income for retirees under age 55. Currently, those under 55 receive a $12,500 deduction, but this bill would lower it to $20,000 (effectively increasing their taxable income by $7,500 annually). The change applies to military retirement income received during the taxable year, directly affecting Maryland residents who are military retirees under 55. The bill amends Section 10-207(q) of Maryland's tax code and takes effect July 1, 2026.
