Self-Employed Tax Calculator — Maryland (2026)
Self-employed in Maryland? Your tax bill has three layers that a W-2 employee never sees in full: 15.3% self-employment tax on 92.35% of net profit, federal income tax, and Maryland state income tax. This calculator applies all three to your 2026 net profit and shows the quarterly amount you should be setting aside. Maryland uses a progressive income tax with 8 brackets running from 2.00% up to 5.75%, applied after a state standard deduction of $2,550.

Self-employment tax vs Maryland income tax
Self-employment tax is federal and identical in all 50 states: 12.4% Social Security up to $184,500 of net earnings plus 2.9% Medicare with no cap. Half of it is deductible against income tax, which is why the calculator subtracts it before applying brackets.
Maryland then taxes essentially the same profit figure at 2.00%–5.75%. On $80,000 of net profit that adds roughly $3,358 to the bill.
Every Maryland county (and Baltimore City) charges an additional county income tax of 2.25%–3.20%. Baltimore City: 3.20%. This estimate excludes local tax.
Deductions that matter for Maryland freelancers
Net profit — not gross revenue — drives every number here. Ordinary and necessary business expenses reduce SE tax, federal tax, and Maryland tax simultaneously: the 2026 standard mileage rate of $0.67/mile, home-office square footage, software, equipment, professional insurance, and the self-employed health insurance deduction.
Retirement plans go further. A SEP-IRA or solo 401(k) reduces income tax (though not SE tax) and is often the largest single deduction available to a profitable biotech contractor in Baltimore.
Working for yourself in Maryland
Maryland's economy leans on biotech, defense, and shipping, which shapes the contractor market around Baltimore — and your fixed costs. With one-bedroom rent near $1,450, a freelancer needs meaningfully more gross revenue than an employee to reach the same lifestyle, because there is no employer paying half of FICA.
Maryland is the only US state where every county levies its own income tax on top of the state rate — combined rates can exceed 8.95%.
Local and payroll taxes Maryland adds on top
County income tax of 2.25%–3.20% is withheld on top of the state rate depending on where you live. That deduction sits outside the federal and state income tax lines, so build it into your own budget on top of the numbers above.
Every Maryland county (and Baltimore City) charges an additional county income tax of 2.25%–3.20%. Baltimore City: 3.20%. This estimate excludes local tax.
Nobody withholds these for you when you are self-employed in Maryland. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Maryland
Maryland holds income-tax reciprocity agreements with District of Columbia, Pennsylvania, Virginia and West Virginia. If you commute between them, your wages are taxed only by your state of residence — file the exemption certificate with your employer so the wrong state is not withheld from every paycheck.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Baltimore resident spending part of the year at a client site in Virginia may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Maryland tax bill
Maryland charges a 6% state sales tax, homeowners pay an average effective property tax of 1.05% of market value, and the minimum wage in force during 2026 is $15.00 an hour.
6% statewide with no local sales tax — the counties tax income instead.
Income tax is only one part of a state's take. Maryland recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. Maryland exempts Social Security and offers a pension exclusion above $36,000 for filers 65+.
Maryland vs Virginia on the same salary
On a $90,000 salary, a single filer keeps about $68,044 a year in Maryland against roughly $67,716 in Virginia — a difference of $327, or $27 a month.
Effective combined rates are 24.4% in Maryland and 24.8% in Virginia. Set that gap against living costs: index 115 here versus 102 there, with property tax at 1.05% and 0.87% respectively.
