Choosing the business vehicle

The following Owner-Managed Businesses guidance note Produced by Tolley provides comprehensive and up to date tax information covering:

  • Choosing the business vehicle
  • Differing rates of tax
  • Sole trader or partner in a partnership
  • Company
  • Payment of tax on extraction of profits
  • Losses in the early years of the business
  • Business vehicles and future plans
  • Non-tax considerations for business vehicles

When a person decides to start in business, consideration should be given as to the most suitable type of entity for the business. This decision will depend on legal, commercial and administrative factors, as well as taxation.

When advising on which type of business vehicle to choose, this guidance note summarises the main tax considerations in deciding which business structure is appropriate for the business owner. A comparison document which summarises both practical and tax differences can be found in the Starting the business ― overview guidance note, together with checklists of the various issues to consider.
