US / UK / Canada
Simplified vs actual
Which method wins
Estimates only, not tax advice. Figures use current published flat-rate amounts and a simplified actual-expense apportionment. They ignore depreciation, capital cost allowance, and country-specific eligibility rules (for example, US W-2 employees generally cannot claim this deduction). Speak to a tax professional before filing.
