As a self-employed person, you pay tax on your net profits—that is, your business income minus allowable expenses.
You may also be taxed on:
- Other income (e.g. rental income, dividends)
- Capital gains from selling business assets (e.g. property or equipment)
Your net profit is the basis for calculating:
- Income Tax
- PRSI (Pay Related Social Insurance)
- USC (Universal Social Charge)
