How USA Sales Tax Calculations Work
The calculations behind sales tax are basic percentages, but the complexity comes from regional rules. US merchants apply rates by identifying the **shipping or point of sale zip code**.
State Tax Amount = Purchase Price × (State Base Rate / 100)
Local Tax Amount = Purchase Price × (Local District Rate / 100)
Total Tax Amount = State Tax Amount + Local Tax Amount
Total Invoice Cost = Purchase Price + Total Tax Amount
