This calculator computes the exact sales tax on a Nashville purchase using the 9.75% combined rate — Tennessee’s 7% state tax plus Davidson County’s 2.75% local option. It also handles the lower grocery rate and Tennessee’s single- article local cap.
How it works
General goods use the full combined rate. Qualifying groceries use a reduced 4% state rate. The local 2.75% only applies to the first $1,600 of a single article:
state_rate = grocery ? 0.04 : 0.07
local_base = min(amount, 1600)
local_tax = local_base * 0.0275
state_tax = amount * state_rate
total_tax = state_tax + local_tax
Example
A $50 general purchase is taxed 50 * 0.0975 = $4.88, for a total of $54.88. A
$50 grocery order is taxed at 6.75% ($3.38), totaling $53.38.
Notes
The single-article cap means the 2.75% local tax stops after $1,600 on one item. Very large single items also carry an extra Tennessee state single-article tax between $1,600 and $3,200, which this standard calculator does not add. Restaurant and prepared food use the full general rate.
