South Dakota taxes cigarettes and alcohol with per-unit excise taxes that are paid by wholesalers and folded into the shelf price before sales tax is even added. Cigarettes are taxed per pack and alcohol per gallon, with different rates for beer, wine, and spirits. This tool turns packs, gallons, or bottles into the total excise embedded in your purchase.
How it works
For cigarettes the tax is packs times the per-pack rate; for alcohol it’s gallons times the category’s per-gallon rate:
cigarette tax = packs × $1.53 per pack
alcohol tax = gallons × per-gallon rate
beer ≈ $0.27/gal
wine ≈ $0.93/gal (≤14% ABV)
spirits ≈ $3.93/gal
A gallon is 128 fluid ounces, so the bottle-to-gallon helper divides your bottle size into 128 to convert standard 750-milliliter or 12-ounce containers into gallons before applying the rate.
Example and notes
Two packs of cigarettes carry 2 × 1.53 = 3.06 dollars of state excise. A case
of 24 twelve-ounce beers is 24 × 12 ÷ 128 = 2.25 gallons, so the beer excise is
2.25 × 0.27 ≈ 0.61 dollars. A 750-milliliter bottle of spirits is about
0.198 gallons, for roughly 0.198 × 3.93 ≈ 0.78 dollars of liquor excise.
These excise figures are separate from and added before South Dakota’s general
sales tax. Rates vary by state and by product strength, so confirm current
figures for high-proof or fortified products.
