How 1099 quarterly tax works in Maryland
Self-employed workers pay the full 15.3% Social Security + Medicare (the "self-employment tax") on 92.35% of profit, plus federal income tax, plus Maryland state income tax. The IRS expects this in four estimated payments rather than a single April bill. Maryland’s state rates look moderate, but every county (and Baltimore City) layers a local income tax of roughly 2.25%–3.2% on top.
Frequently asked questions
How much should I set aside for taxes as a 1099 contractor in Maryland?
It depends on profit, but as a rough guide a single filer with $60,000 of net 1099 profit in Maryland owes about $14,070 total for 2026 — roughly $3,517 per quarter. That covers 15.3% self-employment tax, federal income tax, and Maryland state income tax. Use the tool for your numbers.
When are 2026 quarterly taxes due?
Federal estimated taxes for 2026 are due April 15, June 15 and September 15, 2026, and January 15, 2027. Pay federal with IRS Form 1040-ES; most states have their own estimated-tax vouchers with similar dates.
What counts as profit?
Your 1099 / self-employment income minus legitimate business expenses (software, equipment, mileage, home office, etc.). Self-employment tax and income tax apply to profit, not gross revenue — so tracking deductions directly lowers what you owe.
Does Maryland charge state income tax on 1099 income?
Yes. Maryland’s state rates look moderate, but every county (and Baltimore City) layers a local income tax of roughly 2.25%–3.2% on top. The tool estimates it on your profit.
