What does inside / outside IR35 mean?

Inside IR35 means HMRC treats your contract as disguised employment - you're taxed as a PAYE employee of the end client (or umbrella). Outside IR35 means you're genuinely self-employed and can operate through your own limited company.

Is outside IR35 still worth it post-2024 NI cuts?

Less so than before. With employee NI cut to 8%, Class 4 NI to 6%, and Corporation Tax up to 26.5% marginal, the gap has narrowed to a few thousand pounds at typical contractor rates. Still worth it at lower turnover (<£80k), closer to a wash at £100k+.

How do you model outside IR35?

We use the standard 'tax-efficient' structure: £12,570 director salary (uses full Personal Allowance, no Income Tax) + all remaining post-CT profits as dividends. Your £500 dividend allowance applies, then 10.75%/35.75%/39.35% dividend rates.

What Corporation Tax rate do you apply?

From April 2023: 19% on the first £50,000 of profit, effectively 26.5% on the marginal band £50,000-£250,000, and 25% above £250,000. 2023-24 used flat 19% for small profits before the reform took effect.

Do you model IR35 pre-April-2021 rules?

No - we assume the post-2021 off-payroll rules where IR35 status is determined by the end client (for medium/large businesses) or by you (for small-client engagements).
