For information on property tax rates, exemptions, credits and forms, visit the State Department of Assessments and Taxation (DAT). The agency administers and enforces the property assessment and property tax laws throughout the state.

Tax Incentives

The state also offers a variety of tax incentives, including ones geared toward life sciences and technology, to help businesses grow and prosper. See the Funding and Incentives section for more details on tax incentive programs. In addition to these tax exemptions and credits, the state has:

  • No gross receipts tax on manufacturers
  • No corporate franchise tax
  • No unitary tax on profits
  • No income tax on foreign dividends (if the corporation owns 50% or more of the subsidiary)
  • No tax on intangible property
  • No separate school taxes

Corporate Taxes

Every corporation and association having income allocable to the State of Maryland is required to file an income tax return with the state. The corporate tax rate is 8.25 percent of the net income allocable to Maryland. When compared to the top rates of surrounding and competing states, Maryland compares favorably, with a lower top rate than California, Illinois, Delaware, New Jersey and Pennsylvania.

Note: Top rate for states with multiple brackets. 

Tax aficionados, read on for additional details:

  • Depreciation allowances in the state follow the federal Modified Accelerated Cost Recovery System.
  • A corporation, in computing Maryland taxable income, may deduct from federal net taxable income dividends received from foreign subsidiaries, if the corporation owns 50 percent of more of the foreign subsidiary.


  • Beginning in 2018, Maryland is changing the way in which income tax for multi-state corporations is calculated, by moving from the three-factor apportionment to Single Sales Factor Apportionment Benefits for businesses that invest in payroll and property in the State.

  • Single Sales Factor Apportionment will be phased in over the next five years.

  • By tax year 2022, most corporations subject to the corporate income tax that carry on trade or business both within and out of Maryland must allocate to the State the part of the corporation's Maryland modified income attributed to activity in the state using an apportionment formula in which Maryland modified income is multiplied by 100% of the sales factor. The formula will be phased in as follows:

    • For tax years beginning in 2018, the sales factor is weighted three times;
    • For tax years beginning in 2019, the sales factor is weighted four times;
    • For tax years beginning in 2020, the sales factor is weighted five times;
    • For tax years beginning in 2021, the sales factor is weighted six times;
    • For tax years beginning in 2022, the single sales factor apportionment formula is used.

  • A corporation with its worldwide headquarters in Maryland with at least 500 full-time employees at the headquarters may elect to calculate its Maryland modified income attributed to activity in the state using a three-factor, double-weighted sales factor.

Non Corporate Business Income Tax

Subchapter S Corporations, limited liability corporations, partnerships and sole proprietorships report income on their personal income tax returns.

Personal Income Tax

The state requires all employers to withhold both state and local income taxes. Maryland uses federal adjusted gross income as the starting point for determining taxable income for the state. The state personal income tax is a graduated rate, peaking at 5.75 percent on taxable income over $300,000 for joint filers and $250,000 for single filers. Below find local personal income tax rates from our Data Explorer; and for more details visit the Comptroller of Maryland's website.​

Property Taxes

Real Property taxes

Real property in Maryland is appraised at market value and taxed on assessed value. The assessment is full value, or 100 percent of market value. Both state and local real property taxes are applied to assessed value. Municipalities may also tax real property, and county rates may vary between incorporated and unincorporated areas. For details visit the DAT​ website.​
