What this calculator does
Baltimore shoppers often expect a stack of city, county, and state taxes, but Maryland centralizes sales tax at the state level. The combined Baltimore rate is therefore the statewide 6%, with no separate local add-on. This tool computes the exact tax and grand total for a purchase, and accounts for the most common Maryland exemption categories.
How it works
The core formula is straightforward:
tax = taxable_amount * rate
total = taxable_amount + tax
The rate depends on the item type under Maryland law:
- Standard goods and prepared food: 6%
- Unprepared grocery staples: exempt (0%)
- Alcoholic beverages: 9%
The calculator applies the correct rate based on your selection. Because Maryland prohibits county and municipal sales taxes, the Baltimore “combined” rate never exceeds the state rate for a given category.
Example and notes
For a $100 standard purchase: tax = 100 * 0.06 = $6.00, total = $106.00. For a $100 alcohol purchase: tax = 100 * 0.09 = $9.00, total = $109.00. For $100 of unprepared groceries: tax = $0.00, total = $100.00. Maryland’s exemption line can be subtle — candy, soda, and prepared deli items are taxable even though raw produce is not. Always verify category treatment with the Comptroller of Maryland for unusual items.
