Why this matters for new graduates
A first full-time job brings the first real payslip, and understanding the deductions on it builds good habits early.
Worked example
Here is the calculation with sample figures. Change any number in the Home Office Deduction Calculator to run your own.

| Tax rate (%) | 22% |
| Deduction | $1,000.00 |

Home office deductions: how it works
A simplified home office method multiplies the office area by a fixed rate, up to a cap.
The space usually has to be used regularly and exclusively for business.
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.
| Office area (sq ft) | 200 |
| Tax rate (%) | 22% |
| Deduction | $1,000.00 |
|---|---|
| Tax saved | $220.00 |
