Tax Deduction
Washington County local tax is calculated separately from Maryland state income tax. This means:
- Local tax is in addition to state tax, not instead of it
- Both taxes are calculated on your taxable income (or wages, depending on the tax type)
- Your employer withholds both local and state taxes from your paycheck
- You may be able to deduct local tax on your state tax return, depending on Maryland tax rules
