    The issue of whether to run your business as a company or a sole trader or partnership is an important one. In this factsheet, we summarise the potential tax savings available from operating as a company.

    Is trading as a limited company the best option?

    In our view it is generally beneficial, in tax terms, to trade as a limited company as there are annual tax savings.

    Is it better to take a dividend rather than an increase in salary?

    In our view there is generally a benefit for a director shareholder to take a dividend rather than further salary.

    Tax savings

    The examples below give an indication of the 2021/22 tax savings that may be achievable for spouses or civil partners who are currently in partnership.

    Tax and NI Payable:TaxNI 
    As partners£8,067£22,56
    As company£7245£19,782
    Potential saving£822£2785

    The extent of the savings is dependent on the precise circumstances of the couple’s tax position and may be more or less than the above figures.

    The examples are computed on the basis that the couple:

    • share profits equally
    • have no other sources of income
    • both take a salary of £8,840 from the company with the balance (after corporation tax) paid out as a dividend

    When might a company be considered?

    A company can be used as a vehicle for:

    • a profitable trade
    • buy-to-let properties

    Summary of relevant tax and national insurance (NI) rates 2021/22

    Taxation of dividends

    The cash dividend received is the gross amount potentially subject to tax.

    The rates of tax on dividend income are 7.5% for basic rate taxpayers, 32.5% for higher rate taxpayers and 38.1% for additional rate taxpayers.

    A Dividend Tax Allowance taxes the first £2,000 of dividends received in a tax year at 0%.

    National Insurance

    The rate of employees’ national insurance contributions (NICs) is 12% on earnings in excess of the Primary threshold (£9,568 for 2021/22) up to the Upper earnings limit.

    The rate reduces to 2% on all earnings over the NIC upper earnings limit (£50,270 for 2021/22).

    The rate of NICs for the self-employed is 9%, on profits above £9,568, reducing to 2% on profits above £50,270 for 2021/22.

    Employers pay National Insurance at 13.8% on salary in excess of the Secondary threshold (£8,840 for 2021/22). Employer’s NIC is also payable on benefits in kind provided to employees.

    Dividends are not subject to National Insurance, making dividends much cheaper than salary when the amount being drawn from the company exceeds the lower NIC threshold.

    Pension provision

    As an employee/director of the company, it should be possible for the company to make pension contributions (subject to limits) to a registered fund irrespective of the salary level, provided it is justifiable under the ‘wholly and exclusively’ rule.

    Pension contributions are deemed to be a private expense for sole traders or partners.

    Other tax issues

    It is all too easy to focus exclusively on the potential annual tax savings available by operating as a company.

    However, other tax issues may be significant and should not be underestimated.

    Capital gains

    Incorporating your existing business will involve transferring at least some of your assets (most significantly goodwill) from your sole trade or partnership into your new company.

    The transfer of goodwill may create a significant capital gain although there is a mechanism for deferring the gain until any later sale of the company if the business is transferred in exchange for shares in the company

    Relief for goodwill

    Generally, where goodwill is sold to the company for cash or debt on or after 3 December 2014, individuals are prevented from claiming Business Asset Disposal Relief (BADR), and capital gains tax (CGT) arises on the gain.

    The exceptions to this rule are that a claim to BADR is allowed:

    • for partners in a firm who do not hold or acquire any stake in the successor company
    • where the individual claiming relief holds less than 5% of the shares and the voting power of the acquiring company
    • where an individual holds 5% or more of the shares or voting power if the transfer of the business to the company is part of arrangements for the company to be sold to a new, independent owner

    Property taxes

    Depending on where the property is situated, there will be Stamp Duty Land Tax (SDLT), Land and Buildings Transaction Tax (LBTT) or Land Transaction Tax (LTT) charges to consider when assets are transferred to a company.

    Goodwill and debtors do not give rise to a charge, but land and buildings may do so. Although you may not receive payment for any property that you transfer to the company, the transfer is deemed to have been made at the property’s Market Value.

    The tax is payable by the company

    Income tax

    The precise effects of ceasing business in an unincorporated form, including ‘overlap relief’ need to be considered. Timing of the transfer to a Limited company can be critical if your accounts year end does not fall at the end of the tax year.

    Capital allowances

    Once again, the position needs to be carefully considered.

    Other advantages

    There are many other non-tax advantages of incorporation some of which are summarised below.

    Limited liability

    A company normally provides limited liability. If a shareholder’s shares are fully paid he cannot normally be required to invest any more in the company. This means that your risk of loss is limited to however much you have paid for your shares.

    However, banks often require personal guarantees from the directors for borrowings. The advantage of limited liability will generally apply in respect of liabilities to other creditors.

    Legal continuity

    A company will enjoy legal continuity as it is a legal entity in its own right, separate from its owners (the shareholders). It can own property, sue and be sued.

    Transfer of ownership

    Effective ownership of the business may be more readily transferred, in comparison to a business which is not trading as a limited company.


    Normally a bank is able to take extra security by means of a ‘floating charge’ over the assets of the company and this will increase the extent to which monies may be borrowed against the assets of the business.


    The existence of corporate status sometimes adds to the credibility or commercial respectability of the business to the outside world.

    Pension schemes

    The company could establish an approved pension scheme which may provide greater benefits than self-employed schemes.

    Staff incentives

    Employees may, with adequate safeguards, be offered an opportunity to acquire shares in the business, reflecting their position in the company.


    No analysis of the position would be complete without highlighting potential disadvantages.


    The annual compliance requirements for a company in terms of administration and accounting tend to result in costs being higher for a company than for a sole trader or partnership. Annual accounts need to be prepared in a format dictated by the Companies Act and, in certain circumstances, the accounts need to be audited by a registered auditor.

    Details of the directors and shareholders are filed on the public register held by the Registrar of Companies.


    The annual accounts have to be made available on public record – although these can be modified to minimise the information disclosed.


    If you do not have any employees at present, you do not have to be concerned with Pay As You Earn (PAYE) and returns of benefits forms (P11Ds).

    As a company, you may need to complete PAYE records for salary payments and submit details of salary payments on a timely basis under PAYE Real Time Information (RTI) for payments made to the directors.

    You will also need to keep records of expenses reimbursed to you by the company. Forms P11D may have to be completed.


    If you will require regular payments from your company, we will need to set up a system for you to correctly pay dividends.

    Transactions with the business owner

    A business owner may introduce funds to and withdraw funds from an unincorporated business without tax implications. When a company is involved there may be tax implications on these transactions.

    Director’s responsibilities

    A company director may be at risk of criminal or civil penalty proceedings e.g. for the late filing of accounts or for breaking the insolvency rules.
