THE TEN COMMANDMENTS OF UK TAX OPTIMIZATION

  1. Pay yourself £12,570 in salary — tax-free, NI-free, saves Corporation Tax
  2. Take the rest as dividends — no NI, lower tax rates than salary
  3. Claim the Employment Allowance — £10,500 off employer NI (if you employ others)
  4. Use your £3,000 CGT allowance every year — use it or lose it
  5. Maximize pension contributions — tax relief at your marginal rate, up to £60k/year
  6. Keep R&D records if you’re developing anything new — could be worth thousands in credits
  7. Use AIA/Full Expensing for all equipment purchases — 100% deduction in year one
  8. Plan IHT early — gifts out of income are unlimited and immediate; 7-year PETs need time
  9. If selling a business, claim BADR — 18% vs 24% on up to £1M of gains
  10. If investing in startups, use SEIS/EIS — 50%/30% tax relief plus CGT exemption
