Planning points/pitfalls of incorporation

  • Setting up the share structure and articles of the new company correctly from the outset.
  • Choosing the most advantageous method of incorporation with regard to available CGT reliefs.
  • Valuation of assets, including goodwill. There are also special rules for Goodwill and trade-related properties and valuation may impact on the amount of Stamp Duty Land Tax (SDLT) payable.
  • The write-off of Goodwill in the new company may have adverse effects where it does not qualify for tax relief.
  • A number of VAT issues can arise when incorporating an existing business.
  • PAYE for the new directors and transfer of an existing PAYE scheme.
  • If the business has significant debts or liabiliities or loans you will need to consider how to deal with these too.
