As part of the greater Gaithersburg, MD economy within Montgomery County, Rio businesses share the same Maryland tax and compliance landscape as the rest of the area. Our remote-first process means you get a dedicated bookkeeper and clean monthly financials no matter where in Gaithersburg you are located - reconciled accounts, categorized transactions, and monthly profit-and-loss and balance-sheet reporting you can actually use.
Maryland is one of the few states with a local income tax: every county and Baltimore City levies its own 'piggyback' income tax, from about 2.25% up to 3.30% of your Maryland taxable income, on top of a graduated state income tax that reaches 5.75% (and, new for 2025, brackets of 6.25% and 6.5% on high incomes). The sales tax is a flat 6% statewide with no local add-on, plus a new 3% tax on certain data and IT services that took effect in 2025. Getting the local income tax right and the right sales-tax treatment on services is exactly what we do.
