Business Tax Planning Checklist

For business owners, year-end planning involves multiple considerations across corporation tax, VAT, and personal tax obligations. Here's your comprehensive checklist:

Business Planning Actions
Essential tasks for business owners before year-end
  • Review and update business structure for tax efficiency
  • Maximize Annual Investment Allowance (£1 million limit)
  • Consider timing of major equipment purchases
  • Review R&D tax credit opportunities
  • Optimize salary vs dividend strategies
  • Plan corporation tax payments and cash flow

  • Consider pension contributions for directors
  • Evaluate capital gains tax planning opportunities
  • Review business insurance and professional indemnity

Corporation Tax Strategies:

With corporation tax rates at 19% for profits up to £250,000 and 25% above this threshold, timing becomes crucial. Consider:

  • Accelerating deductible expenses into the current year
  • Timing equipment purchases to maximize capital allowances
  • Reviewing R&D tax credit opportunities
  • Planning director remuneration strategies

VAT Considerations:

Review your VAT position and consider whether any scheme changes would be beneficial:

  • Evaluate Flat Rate Scheme eligibility and benefits
  • Consider Annual Accounting Scheme for cash flow benefits
  • Review partial exemption calculations
  • Plan major purchases to optimize input VAT recovery

Personal Tax Planning Checklist

Individual taxpayers have numerous opportunities to reduce their tax liability through careful planning:

Personal Planning Actions
Key considerations for individual taxpayers
  • Maximize pension contributions within annual allowance
  • Consider ISA contributions (£20,000 limit)
  • Review capital gains tax position
  • Plan charitable donations for tax relief
  • Consider income shifting opportunities
  • Review investment portfolio for tax efficiency
  • Plan timing of asset disposals
  • Consider Enterprise Investment Scheme (EIS)
  • Review inheritance tax planning
  • Update will and estate planning documents

Pension Planning:

Pension contributions remain one of the most effective ways to reduce tax liability while building retirement wealth:

  • Annual Allowance: Use the full £60,000 allowance (or £10,000 if you've accessed pension benefits)
  • Carry Forward: Use unused allowances from the previous three tax years
  • Tapered Allowance: High earners should check if their allowance is reduced

Capital Gains Planning:

With capital gains tax rates at 10%/20% for most assets and 18%/24% for residential property, timing disposals can be crucial:

  • Use the annual exempt amount (£6,000 for 2024-25)
  • Consider timing of asset disposals across tax years
  • Review Business Asset Disposal Relief eligibility
  • Consider spouse transfers to utilize both exemptions
