How tax brackets work: what freelancers need to know
How tax brackets work explained for freelancers, with a worked example, a checklist and the mistakes to avoid.
Why this matters for freelancers
No employer withholds tax for freelancers, so every invoice should be treated as partly the tax authority's money. Getting the numbers right early avoids a painful bill at year-end.
Worked example
Here is the calculation with sample figures. Change any number in the Effective Tax Rate Calculator to run your own.
| Income tax | 18,000.00 |
| Annual income | 120,000.00 |
| Effective rate (%) | 15% |
|---|
How tax brackets work: how it works
Progressive tax systems split income into bands. Each band is taxed at its own rate, and moving into a higher band only affects the income inside that band.
That is why a raise never reduces your take-home pay: only the extra income is taxed at the higher rate.
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.
| Income tax | 54,000.00 |
| Annual income | 360,000.00 |
| Effective rate (%) | 15% |
|---|
Using the calculator step by step
- Open the Effective Tax Rate Calculator.
- Enter your own figures on each numbered line.
- Set the rate to the one that applies to you. Defaults are examples, not advice.
- Read the result and the formula below it.
Key terms
- Withholding
- Tax deducted at source, by an employer or payer, before the money reaches you.
- Reduced rate
- A lower rate that applies to specific categories, often essentials such as food, medicine or books.
- Deduction
- An amount subtracted from taxable income. It saves tax equal to the deduction times your marginal rate.
- Gross amount
- The amount after tax is added, which is usually what a consumer pays.
- Marginal rate
- The rate applied to the next unit of income. It decides how much of a raise or a deduction you keep.
A quick checklist for freelancers
- Find your current bands for the tax year.
- Calculate tax band by band, not on the whole income.
- Compare marginal and effective rates.
Common mistakes to avoid
- Believing a raise can push all income into a higher rate.
- Ignoring deductions that lower taxable income.
