2. Types of Taxes in TaoRocket

TaoRocket supports different tax types that affect calculation order and amounts:

  • Non-Fiscal Included Taxes: Taxes included within the pre net sales amount.
  • Non-Fiscal Excluded Taxes: Taxes applied on the pre net sales minus non-fiscal included taxes.
  • Fiscal Included Taxes: Taxes included but calculated on the pre net sales plus non-fiscal excluded taxes.
  • Fiscal Excluded Taxes: Taxes added on top, calculated on pre net sales plus non-fiscal excluded taxes minus fiscal included taxes.

3. Tax Calculation Order and Formula

TaoRocket calculates taxes in the following sequence:

  • Calculate Non-Fiscal Included Taxes from pre net sales.
  • Calculate Non-Fiscal Excluded Taxes from (pre net sales - non-fiscal included taxes).
  • Calculate Fiscal Included Taxes from (pre net sales + non-fiscal excluded taxes).
  • Calculate Fiscal Excluded Taxes from (pre net sales + non-fiscal excluded taxes - fiscal included taxes).

4. Example Calculation

Suppose:

  • Pre net sales: 1,000 THB
  • Non-fiscal included tax: 5%
  • Non-fiscal excluded tax: 2%
  • Fiscal included tax: 7%
  • Fiscal excluded tax: 3%

Calculation steps:

  • Non-fiscal included tax = 1,000 * 5% = 50 THB
  • Non-fiscal excluded tax = (1,000 - 50) * 2% = 19 THB
  • Fiscal included tax = (1,000 + 19) * 7% = 73.33 THB
  • Fiscal excluded tax = (1,000 + 19 - 73.33) * 3% = 28.01 THB
  • Total taxes = 50 + 19 + 73.33 + 28.01 = 170.34 THB
