Maryland State Income Tax Guide (2026)

Maryland has a state income tax that is calculated separately from your federal income tax. Your employer withholds state income tax from each paycheck based on your filing status, income level, and the information you provide on your state withholding form.

State income tax is calculated using progressive tax brackets, meaning different portions of your income are taxed at different rates. Your marginal state tax rate is the rate on your highest dollar of income, while your effective state tax rate is the average rate you pay on all your income.

The amount withheld depends on your gross pay, pay frequency, filing status, and withholding allowances. State tax is calculated on your taxable income after the standard deduction and other adjustments.

Maryland uses a progressive tax system with multiple brackets. The tax rate increases as your income increases, but only the income within each bracket is taxed at that bracket's rate. This means your effective state tax rate—the average rate you pay on all your income—is typically lower than your marginal rate.

The specific brackets and rates vary by filing status. Your effective state tax rate depends on your total income, filing status, and deductions. Use our calculator to see exactly how Maryland state tax affects your specific situation.

Some cities and municipalities in Maryland levy local income taxes in addition to state income tax. These local taxes are typically a flat percentage of your income and are withheld by your employer if you work in a jurisdiction that requires it.

Local tax rates vary by jurisdiction and can change annually. Your employer should automatically withhold local taxes if applicable to your work location. If you're unsure whether you're subject to local tax, check with your employer or local tax authority.

In Maryland, bonuses are taxed at your regular state income tax rate. The withholding method your employer uses can make it seem like bonuses are taxed more heavily, but when you file your tax return, bonuses are taxed at your actual marginal rate.

If your employer uses the aggregate method, they add the bonus to your regular paycheck and calculate withholding as if you earn that amount every pay period. This can result in higher withholding because it assumes you're in a higher tax bracket.

In Maryland, the value of vested RSUs is subject to state income tax at your regular state tax rate. If you sell the shares immediately after vesting, you may have little to no capital gains. If you hold the shares and sell later, any appreciation is subject to capital gains tax at both the federal and state level.

Several situations can cause unexpected changes in your take-home pay in Maryland:

• Mid-year raises: A raise mid-year can push you into a higher state and federal tax bracket, increasing your effective tax rate for the remainder of the year. This means more tax is withheld from each paycheck.
• Multiple jobs: If you work multiple jobs, each employer withholds as if that job is your only income. This can result in under-withholding, especially if you're in Maryland and state tax brackets are progressive.
• Overtime: Overtime pay is taxed at the same rate as regular pay, but higher gross pay means more tax withheld. The additional withholding may make it seem like overtime is taxed more heavily, but it's just more income being taxed at your regular rate.
• Local tax changes: Moving to a different city or municipality in Maryland can change your local tax rate. If you start working in a new jurisdiction, your employer should automatically update withholding.

Maryland state income tax directly reduces your take-home pay. The amount depends on your income level, filing status, and the specific tax rates in Maryland. Combined with federal taxes, state tax can significantly impact your net pay.
