Limited Company v Sole Trader

> the tax comparison.


Minimising the tax paid on profits is a key aim of most SME businesses. The tax benefits of trading through a limited company, as compared to operating as a sole trader or partnership, soon becomes attractive as profits grow.


As the tax calculations below illustrate, based on the UK tax rates and thresholds for 2016/17 (ie applying the new dividend taxation rules), a limited company still results in a lower overall tax/NIC charge than a sole trader (allowing for the extra accountancy fees incurred through trading as a limited company), whilst profits are above approximately £30k pa: 


Annual Profits

 £75,000  £100,000
Sole Trader

 - Class 2  -  -  -  -
 - Class 4  153  3,309  3,809  4,309
 Income Tax        
 - 20%  -  6,400  6,400  6,400
 - 40%  -  2,800  12,800  22,800


 £153  £12,509  £23,009  £33,509
Ltd Company      
Corporation Tax        
 - 20%  400  8,400  13,400  18,400
 Income Tax/NIC        
 - Various rates  -  1,910  8,070 14,570


 £400 £10,310 £21,470  £32,970
Lowest Tax/NIC  Sole Trader  Company  Company Company
Saving:  £247   £2,199 £1,539   £539


In the above comparison, in order to minimise tax in the company example, the salary/dividend remuneration mix has to be optimised.

As well as the amount of direct taxation due on profits, businesses should consider a number of further matters before deciding which of the two trading mediums is best advice:

Other tax matters

  • IR35 tax,
  • Use of other family members' tax allowances and reliefs, 
  • Timing of tax payments,
  • The profit or loss profile of the business over time, 
  • The more generous company tax deduction rules,
  • Capitalising goodwill on conversion of existing business, 
  • Double taxation,
  • Future, further unforeseen changes in tax rules.

Commercial matters

  • Protection,
  • Confidentiality,
  • Image and credibility in the marketplace,

  • Client expectations (particularly for consultancy assignments),

Cost and practical matters

  • Audit,
  • The additional administration work and professional fees as a limited company,
  • The discipline required in keeping personal finances separate from business finances,   
  • Credit rating,
  • Use of certain words in the business name,
  • How long into the future that you believe the business will continue to trade.

If you have a work offer, there are various solutions to how you could be engaged:

  1. Directly employed (on the books)
  2. Self employed/sole trader consultant
  3. Limited company contractor (IR35 non applying)
  4. Limited company contractor (IR35 applying)
  5. Through an umbrella employment agency
