- Statutory bracket
- 2% to 5.75% plus mandatory county tax
Maryland's state top rate of 5.75% is only part of the liability. Maryland requires counties to levy a "piggyback" income tax of roughly 3% of the state rate, and 23 of 24 counties do, so a Maryland contractor effectively pays about 5.95% combined. Because counties may set their rate slightly lower, the total varies by county.
Local taxes: The mandatory county piggyback tax is the dominant local layer in Maryland and is not optional in practice. Baltimore City sets its own rates within the statutory band, so the same job pays a different total depending on the county line.
State revenue agency: Comptroller of Maryland.Maryland requires quarterly estimated payments via Form 502 if you expect to owe $1,000 or more, with the standard four federal deadlines. Maryland does not have its own separate voucher form.
Tax Strategy for trade contractors
Trades contractors deduct materials, tools, vehicles, insurance, and licensing, and the vehicle deduction is often the largest. A work van used exclusively for the business supports either the standard mileage rate or a full expense deduction including depreciation, and a dedicated trades vehicle makes the actual-expense method far more favourable than it would for a mixed-use car. Worker's compensation premiums and tools that fall under $2,500 are also deductible.
Trades income follows the construction calendar closely, with a hard winter slowdown and a summer surge. Quarterly income can swing by a factor of three between peak and off-peak, so base vouchers on the trailing twelve months and hold back more aggressively during the busy season rather than spending it.
To avoid underpayment penalties, pay at least 90% of your current-year tax, or 100% of last year's total tax — 110% if your prior-year AGI was above $150,000.

The percentage is measured against gross income rather than net profit because that is the number that actually reaches your bank account and the number you can safely divert.
