Worked Example

Let's calculate the tax for a self-employed individual with $80,000 in income and $15,000 in deductions for the 2023 tax year.

  1. Total Income: $80,000
  2. Deductions: $15,000
  3. Tax Credit: $1,172 (for first $10,000 of income)
  4. Taxable Income: $80,000 - $15,000 - $1,172 = $63,828
  5. Tax Calculation:
    • $48,535 × 5.05% = $2,449.94
    • ($63,828 - $48,535) × 9.15% = $13,444.99
    • Total Tax = $2,449.94 + $13,444.99 = $15,894.93
  6. Net Income: $80,000 - $15,894.93 = $64,105.07

This example shows how deductions can significantly reduce your tax liability and increase your net income.
