Maryland bonus tax questions
What is the Maryland bonus tax rate for 2026?
Maryland's bonus tax rate is 6.5% plus your county's top local rate, which runs from 2.25% in Worcester County to 3.3% in Dorchester County and Kent County. On a $10,000 bonus that is $650 of Maryland tax and $320 of Montgomery County tax.
Is a bonus taxed more than regular pay in Maryland?
No. When you file, a bonus is taxed at the same Maryland rates as the rest of your wages; only the withholding differs. For a single filer with $75,000 of wages, a $10,000 bonus adds $795 to the year's Maryland state and county tax and has $970 withheld, so $175 more is withheld than owed. The extra counts toward your refund.
How much county tax is withheld from a bonus in Maryland?
Maryland withholds 6.5% plus the highest local rate for your county of residence, even in counties with lower rates on lower incomes. In Montgomery County that is $320 of county tax on a $10,000 bonus, on top of $650 of state tax. Local tax is withheld at the guide's rate group for the county, which can be up to 0.05 points above the county's actual rate (Cecil's 2.74% is withheld at 2.75%).
What the calculator leaves out
- The guide lists its local-rate groups, not counties; each county is placed in the lowest group at or above its top rate.
- Local tax is withheld at the guide's rate group for the county, which can be up to 0.05 points above the county's actual rate (Cecil's 2.74% is withheld at 2.75%).
- 6.50% is Maryland's top bracket rate, well above most filers' rate, so bonus withholding usually exceeds the tax.
- Nonresidents of Maryland counties are withheld at a 2.25% state rate instead of a county rate; not modeled.
Federal income tax is withheld at the 22% supplemental rate, 37% on supplemental pay above $1,000,000 in a year. Social Security and Medicare treat the bonus as the year's last pay, so wages above $184,500 owe no more Social Security. Filing status changes only the annual comparison.
