Maryland Tax Guide

Maryland taxes, explained with local context.

MD Tax Guide brings planning tools, plain-language guidance, a county directory and a filing checklist to your iPhone and iPad. Explore state and local taxes and understand the assumptions behind your estimate.

YOUR INCOME, YOUR COUNTY

Follow a three-step income calculator: choose your filing status and residence, enter your income details, then review your inputs.

Start with federal adjusted gross income and supply Maryland additions and subtractions. Use the modeled standard deduction or enter eligible itemized deductions. Include supported personal, dependent, age and blindness exemptions, plus net gains subject to the modeled capital-gain surtax.

See estimated state income tax, local income tax and capital-gain surtax separately, before credits. Review your effective rate, taxable income, deductions, exemptions and state bracket breakdown, or share an estimate summary.

Explore all 23 counties and Baltimore City in the local income-tax directory. Baltimore City and Baltimore County are listed separately. The calculator models the different local calculation methods for Anne Arundel and Frederick.

MORE TOOLS FOR PRACTICAL PLANNING

• Sales and use tax: Estimate tax and total cost for supported categories: general purchases, alcohol, specified IT/data services, adult-use cannabis and confirmed exemptions.

• Property tax: Enter a taxable assessment and combined rate per $100 to estimate annual tax before credits and special charges. Property rates are separate from county income-tax rates.

• State transfer tax: Estimate the Maryland state component, with an eligible first-time Maryland homebuyer option. County transfer tax, recordation tax and other closing costs are excluded.

• Corporation income tax: Explore a general C corporation estimate using Maryland taxable income you have already adjusted and apportioned, before credits.

• Pass-through entity tax: Estimate supported PTE tax using separate individual/fiduciary and entity member bases. Elections, owner credits and taxable bases require separate review.

• Vehicle excise tax: Calculate a base estimate using an already-established MVA taxable value. This is not a complete title or registration quote.

• Inheritance tax: Estimate tax on a confirmed taxable clear value after beneficiary exemptions and taxability have been checked.

• Estate filing threshold: Check a threshold using estate, gift and supported spousal-election inputs. This is not an estate-tax calculation or a determination of every filing obligation.
