How your freelance effective tax rate is calculated in Maryland for 2026
As a self-employed person in Maryland, your total tax burden has three components: self-employment tax (SE tax), federal income tax, and Maryland state income tax. Your all-in effective rate is the total of these three divided by your net profit.
Maryland taxes federal AGI minus the Maryland standard deduction. The deductible half of SE tax and above-the-line deductions that reduce federal AGI flow through to reduce Maryland taxable income.
SE tax and federal income tax
SE tax is 15.3% on 92.35% of net profit up to $184,500 (the 2026 Social Security wage base) and 2.9% above that. One-half of SE tax is deductible above the line, reducing federal AGI. Federal income tax is calculated on federal AGI minus the standard deduction, using the 2026 ordinary income brackets.
Effective rate vs marginal rate
The effective rate is total tax divided by net profit. The marginal rate is the bracket that applies to the last taxable dollar. The combined marginal rate adds the SE tax rate on the next dollar of profit (approximately 14.1% under the Social Security wage base) to the federal income tax marginal rate.

Frequently asked questions
What is the combined effective tax rate for freelancers?+
Your effective tax rate is the total tax you owe (SE tax + federal income tax + state income tax) divided by your total net self-employment income. This is a blended average across all dollars earned, not the rate on the next dollar. The combined marginal rate on the next dollar is higher than the effective rate because earlier dollars are taxed at lower bracket rates.
What is the difference between effective rate and marginal rate?+
Your marginal rate is the tax you pay on the next dollar earned. Your effective rate is the average rate across all dollars. Always plan quarterly estimated tax using the marginal rate on incremental income, but use the effective rate to understand your overall tax burden and what to set aside.
How much should I set aside for taxes as a freelancer?+
Set aside your all-in effective rate as a percentage of each payment you receive. Add a 5% buffer for unexpected income increases. Quarterly estimated tax payments are due April 15, June 16, September 15, and January 15. The IRS safe-harbor rule: pay 100% of the prior year's tax liability (110% if AGI was above $150,000) to avoid underpayment penalties.
What is the effective tax rate for freelancers in Maryland?+
Maryland levies state income tax at graduated rates from 2% to 5.75% plus a county income tax that varies by jurisdiction. This calculator includes the state rate only; county tax is additional. The Maryland standard deduction is between $1,550 and $2,250 single / between $3,100 and $4,500 MFJ (2% of federal AGI, capped). At $80,000 net profit (single), the Maryland state component (before county tax) adds roughly 4.75% to the all-in effective rate.
