This calculator applies Indiana’s combined 7% sales tax to any Indianapolis purchase. Because Indiana does not permit local or county sales taxes, the Indianapolis and Marion County rate is identical to the statewide rate, making the math refreshingly simple.
How it works
Taxable purchases are multiplied by the rate; exempt items (qualifying groceries and prescriptions) are taxed at zero:
taxable = exempt ? 0 : purchase_amount
tax = taxable * (rate / 100)
total = purchase_amount + tax
Example
A $100 taxable purchase at the 7% combined rate incurs $100 * 0.07 = $7.00 in
sales tax, for a total of $107.00. A $100 grocery order of qualifying
unprepared food is exempt, so the total stays at $100.00.
Notes
Indiana taxes prepared food, candy, soft drinks, and supplements even though grocery staples are exempt, so the exemption toggle is a simplification. Rules for digital goods and services differ. Confirm specifics with the Indiana Department of Revenue.
