Withholding tax explained for small business owners
Withholding tax explained for small business owners, with a worked example, a checklist and the mistakes to avoid.
Why this matters for small business owners
Small business owners juggle tax on sales, profits and payroll at the same time. Clear calculations make pricing, cash flow and filing far less stressful.
Worked example
Here is the calculation with sample figures. Change any number in the Withholding Tax Calculator to run your own.
| Amount | 17,500.00 |
| Tax rate (%) | 30% |
| Tax | 5,250.00 |
|---|---|
| Net amount | 12,250.00 |
Withholding tax: how it works
Withholding tax is deducted at source before income reaches you, for example on cross-border dividends, interest or contractor payments.
Treaties can reduce the rate, and the tax withheld can often be credited against your own liability.
A second example with larger figures
Scaling the inputs up shows how the result moves. Percentages stay the same, so the tax grows in proportion to the amount it is applied to.
| Amount | 52,500.00 |
| Tax rate (%) | 30% |
| Tax | 15,750.00 |
|---|---|
| Net amount | 36,750.00 |
