Important Considerations
These are illustrative examples

Actual calculations may vary based on your specific circumstances, annual earnings, and other factors.

Expense claims must be legitimate

All expenses must be "wholly, exclusively, and necessarily" for business purposes and properly documented.

Annual calculations differ

These weekly examples don't account for annual allowances, which may affect the overall tax position.

Professional advice recommended

Always seek professional advice for your specific situation and ensure compliance with all regulations.
