Configure multiple tax rates, compound taxes, and region-specific rules per business. InvoiceBase handles the math so you don't have to.

  • Unlimited tax rates per business
  • Name each rate for clarity (e.g., GST, PST, VAT)
  • Automatic application to all line items
  • Real-time subtotal and total recalculation

Compound Tax

Compound Tax Made Easy

Need to apply a tax on top of another tax? Enable compound tax mode and InvoiceBase will stack your rates correctly — common in Canadian provinces and other multi-layered tax systems.

  • One-click compound tax toggle
  • Taxes calculated in the correct stacking order
  • Perfect for GST + PST / QST setups
  • Transparent breakdown on every document
Compound Tax Compound Tax Included SUBTOTAL $2,500.00 + GST (5%) on $2,500.00 + $125.00 + QST (9.975%) on $2,625.00 + $261.84 = Total $2,886.84
Per-Item Control

  • Enable or disable tax per line item
  • Mix taxable and non-taxable items on one invoice
  • Clear on-screen indicators for tax status
  • Totals recalculate instantly
