Maryland State Taxes: Income, Property, Sales, and Business Taxes

Maryland operates one of the more layered state tax systems in the country — a structure where state-level rates stack with county-level additions, where a business might navigate four distinct tax regimes simultaneously, and where a homeowner's effective property tax rate depends heavily on which side of a county line the property sits. This page covers the mechanics of Maryland's income, property, sales and use, and business taxes: how each is structured, what drives the rates, where the classifications matter, and where common assumptions go wrong.

Definition and scope

Maryland's tax system is administered primarily by the Maryland Comptroller, the elected official responsible for collecting state income taxes, sales and use taxes, and a range of excise taxes. Property taxes sit under a parallel structure: the Maryland Department of Assessments and Taxation (SDAT) handles property assessment statewide, while individual counties and Baltimore City set and collect their own property tax rates on top of the state rate.

The system covers four principal tax categories relevant to residents and businesses: the individual income tax, the corporate income tax, the sales and use tax, and property taxes. Business-specific levies — including the pass-through entity tax, local business personal property tax, and various filing fees — add further layers.

Scope and coverage note: This page addresses state and county taxes imposed within Maryland's 23 counties and Baltimore City. Federal tax obligations, taxes imposed by neighboring states on Maryland residents earning income there, and municipal-level taxes beyond county structures fall outside this scope. Certain federal enclaves within Maryland — including facilities within the Baltimore-Washington metropolitan area — may have distinct jurisdictional considerations not covered here.

Core mechanics or structure

Individual Income Tax

Maryland imposes a graduated state income tax with rates ranging from 2% on taxable income up to $1,000 to 5.75% on income exceeding $250,000 (single filers) or $300,000 (joint filers), per the Maryland Comptroller's rate schedules. What makes Maryland's income tax architecturally unusual is the mandatory local income tax — a piggyback tax collected by the state on behalf of each county and Baltimore City.

Local income tax rates in Maryland range from 2.25% to 3.20% depending on jurisdiction (SDAT and Comptroller joint rate tables). Howard County sits at 3.20%. Somerset County sits at 3.20% as well. Montgomery County charges 3.20%. Residents pay both the state rate and their county's local rate simultaneously, calculated on the same Maryland taxable income base. A resident of Howard County earning $100,000 in taxable income faces a combined marginal rate well above 8% at the upper brackets — one of the higher combined state-local income tax burdens in the mid-Atlantic region.

Corporate Income Tax

Maryland's corporate income tax is a flat 8.25% on Maryland taxable income, as set under Maryland Code, Tax-General Article § 10-102. Multistate corporations apportion income to Maryland using a single-sales-factor formula, meaning only the proportion of sales attributable to Maryland customers determines the Maryland taxable base.

Sales and Use Tax

The state sales and use tax rate is 6% (Maryland Code, Tax-General Article § 11-104). Maryland does not permit county-level additions to the sales tax rate — the 6% figure is uniform across all jurisdictions. Alcohol sold for consumption off-premises carries a 9% rate. Certain digital goods and digital code are taxable; many food items purchased for home consumption are exempt.

Property Tax

The state property tax rate for owner-occupied residential property is $0.112 per $100 of assessed value (SDAT FY2024 rate schedule). County rates layer on top of this. Montgomery County's combined rate reaches approximately $1.00 per $100 of assessed value when state and county rates are combined. Baltimore City, which functions simultaneously as a county-equivalent jurisdiction, carries one of the highest combined rates in the state — approximately $2.248 per $100 of assessed value for FY2024, per SDAT published schedules.

Residential assessments are conducted on a three-year cycle. Increases in assessed value are phased in equally over three years under Maryland's homestead tax credit provisions, limiting sudden spikes in taxable assessment for owner-occupied primary residences.

Causal relationships or drivers

Maryland's layered income tax structure exists because the state constitution permits, and the General Assembly has authorized, counties to levy their own income taxes using the state's collection infrastructure. This arrangement — the state acts as collection agent for 24 separate local jurisdictions — was codified decades ago and creates a system where the Maryland General Assembly sets the parameters (minimum and maximum local rates) and counties choose their rate within that band.

Property tax rates are driven by two independent forces: the assessed value set by SDAT (a state function) and the tax rate set by the county council or city council (a local function). When property values rise sharply — as occurred across Central Maryland during the post-2020 housing surge — assessments follow with a lag, and the phase-in mechanism further delays the full impact on tax bills. This means homeowners often experience rising tax bills for years after the market has already peaked.

Corporate income tax rates in Maryland have historically been set with reference to neighboring state competition. Virginia's corporate rate is 6%, Pennsylvania's is 8.99%, and Delaware's is 8.7% (Tax Foundation State Business Tax Climate data). Maryland's 8.25% flat rate sits in the middle of that regional range.

Classification boundaries

Not all income, property, or transactions are treated identically. The classification distinctions that matter most:

Income tax: Maryland follows federal adjusted gross income as its starting point, then applies Maryland-specific additions and subtractions. Military retirement income receives a partial subtraction — up to $5,000 for taxpayers under 55, and up to $15,000 for those 55 and older, per the Comptroller's published guidance. Social Security income is not taxed by Maryland for most filers, though higher-income households above specific thresholds may have a portion included.

Property classification: SDAT classifies real property into categories including residential, commercial, industrial, and agricultural. Agricultural land assessed under the agricultural use assessment program receives substantially lower valuations — a deliberate policy choice to preserve farmland from development pressure, particularly on the Eastern Shore and in Western Maryland.

Sales tax classification: Groceries (food for home consumption) are exempt from Maryland's 6% sales tax. Prepared food, alcohol, and tobacco are taxed at varying rates. Prescription drugs are exempt. Clothing has no special exemption in Maryland — unlike some neighboring states — meaning apparel is fully subject to the 6% rate.

Business entities: Pass-through entities — S corporations, partnerships, and LLCs taxed as partnerships — are subject to Maryland's pass-through entity (PTE) tax, which was made permanent following federal SALT deduction cap workarounds. The PTE tax allows qualifying entities to pay Maryland income tax at the entity level, potentially allowing owners to deduct the payment as a federal business expense.

Tradeoffs and tensions

The local income tax piggyback creates an equity tension that surfaces in conversations about tax policy in Annapolis with some regularity. Higher-income counties can set lower local rates and still generate substantial revenue because their tax base is larger. Lower-income counties set higher rates — the maximum 3.20% — and still generate less revenue per capita. The structure funds local government but doesn't equalize it.

The homestead tax credit, while protecting existing homeowners from assessment shock, creates a different distortion: two identical houses on the same block can carry dramatically different tax bills if one has been owner-occupied for 15 years and the other just sold. New buyers inherit the full assessed value immediately; long-term owners accumulate credit offsets that can amount to thousands of dollars annually.

Maryland's 6% uniform sales tax rate — with no county add-ons — avoids the complexity that characterizes states like California or Tennessee, where local rates create a patchwork. The tradeoff is that the state captures all sales tax revenue centrally and redistributes it, rather than allowing counties to use sales taxes as an independent revenue instrument.

Common misconceptions

"Maryland has no estate tax." Incorrect. Maryland is one of a small number of states — 12 as of 2024, per the Tax Foundation — that still imposes both a state estate tax and a state inheritance tax. The estate tax exemption threshold is $5 million (Maryland Code, Tax-General Article § 7-309). The inheritance tax rate is 10% and applies to transfers to non-close-family recipients.

"The county sets my property assessment." SDAT — a state agency — sets all residential property assessments in Maryland. Counties have no authority over the assessment value; they only set the rate applied to that value. A county cannot lower a homeowner's assessment.

"Maryland's sales tax is 6% on everything." The 6% rate is the general rate, but specific categories diverge sharply: alcoholic beverages for off-premises consumption are taxed at 9%, and vending machine sales carry their own rate structures. The uniform 6% is a useful approximation, not an exact rule.

"Businesses pay corporate income tax." Many Maryland businesses are not C corporations and therefore do not pay corporate income tax — they pay individual income tax through the pass-through structure, often at the combined state-local rates that can exceed 9% at higher income levels. The corporate income tax is specifically a C corporation obligation.

Checklist or steps

The following describes the standard sequence of tax obligations that a newly formed Maryland business entity will encounter:

1. Entity registration — File articles of incorporation or organization with the Maryland Department of Assessments and Taxation, which also serves as the state's business registry.
2. Employer Identification Number — Obtain a federal EIN from the IRS; required before Maryland tax registration can be completed.
3. Maryland Combined Registration — File the Combined Registration Application with the Comptroller to establish accounts for withholding tax, sales and use tax (if applicable), and corporate income tax.
4. Personal property return — File an annual business personal property return with SDAT by April 15 each year; applies to most business entities and covers furniture, fixtures, equipment, and inventory held in Maryland.
5. Local business licenses — Obtain applicable county-level business licenses through the circuit court clerk's office in the county of operation; license fees are based on gross receipts for most business types.
6. Quarterly estimated payments — Corporate income taxpayers with expected Maryland liability exceeding $1,000 must make quarterly estimated payments; pass-through entities with nonresident members have separate withholding obligations.
7. Annual returns — File Maryland Form 500 (corporations), Form 510/511 (pass-through entities), or Form 502 (individual), depending on entity structure, by the applicable deadline.

The Maryland Comptroller's business tax portal provides electronic filing infrastructure for most of these obligations.

The Maryland state taxes overview page on this site provides additional context on how these obligations interact with specific business types and industries.
