Hourly Rate vs Annual Salary: Tax Differences & Contracting Guide (2026)
When comparing a permanent £65,000 salaried position with a £450/day contracting role, looking strictly at headline numbers is dangerously misleading. Contractors must account for unbillable downtime, missing paid annual leave (28 statutory days), employer pension contributions (3%–10%), sick pay, and employer National Insurance deductions under IR35.
1. The Permanent vs Contracting Equivalent Conversion Rule
To match the total financial benefits of a permanent salary, your contracting day rate must exceed the permanent gross salary divided by 180 billable days:
