#### Formula

Taxable Base = Total Material Cost − Exempt / Non-Taxable Portion Combined Tax Rate = Georgia State Rate (4%) + County Local Rate (%) Sales Tax Due = Taxable Base × Combined Tax Rate Total Cost = Total Material Cost + Sales Tax Due

Example: $15,000 in materials in Fulton County (4% local) with no exemptions: Taxable Base = $15,000 − $0 = $15,000 Combined Rate = 4% + 4% = 8% Sales Tax = $15,000 × 0.08 = $1,200.00 Total Cost = $15,000 + $1,200 = $16,200.00
