Income Tax - Addition Modification for Federal Tax-Exempt Income - Study

SB 163 modifies Maryland's income tax calculation by removing a requirement to include certain foreign earned income in taxable income. It specifically exempts income that qualifies for exclusion under federal law (IRS Section 911), such as earnings from work abroad that are already excluded from federal taxes but would otherwise be added to Maryland taxable income. This change directly affects Maryland residents earning qualifying foreign income who currently face state taxation on that income. The bill amends Maryland tax code sections 10-204(a) and 10-204(c)(1)(I) and takes effect for taxable years beginning after December 31, 2025.
