Tax Implications of a Company Buying Its Own Shares
This is a multi-faceted area involving company law, income tax, capital gains tax, and stamp duty. Here is a comprehensive overview:
What the Law Says
1. Default Position: Treatment as a Distribution
Any excess of the consideration paid over the shares' original subscription price is treated as a distribution under CTA 2010/S1000(1)B.
2. The Capital Treatment Exception: CTA 2010/S1033
A payment on redemption, repayment or purchase of its own shares is not a distribution if:
- The company is an unquoted trading company, or the unquoted holding company of a trading group; and
- Either Condition A or Condition B is met.
Condition A requires that:
- The purchase is made wholly or mainly for the purpose of benefiting a trade carried on by the company or any of its 75% subsidiaries;
- It does not form part of a scheme to enable the owner to participate in profits without receiving a dividend, or to avoid tax; and
- The statutory requirements in ss.1034–1043 are met.
Condition B applies where substantially the whole of the payment is applied to discharge an inheritance tax liability on a death, within two years of that death.
3. Statutory Conditions under ss.1034–1043
| Condition | Requirement |
|---|---|
| Residence (s.1034) | The seller must be UK resident in the tax year of purchase |
| Period of ownership (s.1035) | The shares must have been owned by the seller throughout the 5 years ending with the date of purchase (reduced to 3 years where shares are inherited) |
| Reduction of interest (s.1037) | The seller's interest as a shareholder must be substantially reduced — i.e., the seller's subsequent interest must be not more than 75% of their prior interest |
| Group companies (s.1039) | Where the purchasing company is a member of a group, the seller's combined interest in the group must also be substantially reduced |
4. CGT Position for the Seller
Where s.1033 applies, the vendor is treated as receiving a capital receipt, giving rise to a disposal for CGT purposes. Where it does not apply and the payment is a distribution, the amount chargeable to CGT is the total consideration net of any amount subject to income tax, per TCGA 1992/S37.
5. Stamp Duty
Under FA 1986/S66, the SH03 return form submitted to Companies House is treated as an instrument of transfer and is chargeable to Stamp Duty. The SDRT charge is cancelled to the extent that Stamp Duty has been paid on the return (FA 1986/S92(1C)).
6. Reporting Obligation
Under CA 2006/S707, a company buying its own shares must make a return to Companies House (on form SH03) within 28 days of the shares being delivered to it.
7. Subsequent Bonus Issues (Anti-Avoidance)
If a company later makes a bonus issue following a purchase of own shares, a distribution under CTA 2010/S1022 may arise up to the amount of the repayment of share capital — even if s.1033 clearance was obtained and even if the bonus issue recipient is a different member.
HMRC Guidance / Practice
Default Distribution Treatment
Where s.1033 does not apply (e.g., quoted companies, or unquoted companies failing the conditions), a distribution within CTA 2010/S1000(1)B arises. The disposal proceeds consist of two elements: a return of capital on the shares, and the balance treated as a distribution subject to income tax under ITTOIA 2005/S383.
Capital Treatment under s.1033
Where s.1033 applies, the vendor is treated as receiving a capital receipt. However, if the vendor is a share dealer, the receipt will still be trading income.
Trustees
Where a company buys its own shares from trustees, the distribution is treated as income chargeable at the dividend trust rate, with a credit at the dividend ordinary rate (ITA/ss.481–482). However, if s.1033 applies (i.e., clearance has been obtained), ITA/ss.481–482 will not apply.
Advance Clearance
A company can apply in advance to HMRC (via the Clearance and Counteraction Team) for confirmation that s.1033 applies — though clearance is not a statutory requirement. Taxpayers may also apply for clearance that s.1033 does not apply (under CTA 2010/S1044).
Reporting to HMRC
If a company believes s.1033 applies, it must make a return to HMRC within 60 days of the payment, giving particulars and explaining why s.1033 applies — even if clearance has already been obtained.

Under the provisions of the Companies Act 2006, a UK incorporated company is obliged to make a return to the Registrar of Companies giving details of own shares purchased (CA06/S707). The return is made on an SH03 Form (issued by Companies House). Under CA06/S707 it is compulsory for a company buying its own shares to make a return to Companies House within the period of 28 days beginning with the date on which the shares are delivered to it.

If a company undertakes a purchase of its own shares that it believes falls within CTA10/S1033, it must make a return of the transaction to HMRC (CTA10/S1046 (1)). This return must: be made within 60 days of the payment, give particulars of the payment, and explain why the company believes that CTA10/S1033 applies to the payment so as to exempt it from treatment as a distribution. The company must make such a return even if the Commissioners have confirmed that CTA10/S1033 will apply to the paym

A purchase of own shares by a company is often done as a simpler alternative to more complex share reconstructions or organisations. The tax treatment would depend on how the purchase of own shares was carried out. Any excess of the consideration over the shares’ subscription price would be treated as a distribution under CTA10/S1000(1)B when a company is purchasing its own shares unless the applicable legislation from CTA10/S1033 to S1048 applies. The disposal proceeds received from the compan
A company can make a clearance application prior to making a payment on the purchase of its own shares. They will be able to obtain advanced clearance from the Board that any distribution would be an exempt distribution for the Income Taxes Act. Clearance applications are the responsibilities of the Clearance and Counteraction Team in the Business, Assets and International Directorate. For guidance on making a clearance application please see https://www.gov.uk/guidance/seeking-clearance-or-appr
CTA10/S1022 covers the situation where a company repays share capital and subsequently makes a bonus issue of shares, see CTM15420. In appropriate circumstances the bonus issue is treated as a qualifying distribution. Where a company carries out a purchase of own shares, to which CTA10/S1033 treatment may or may not apply, a repayment of share capital results. If a later bonus issue is made by certain close companies at any time after the purchase of own shares, or by other companies within ten
In certain circumstances, CTA10/S1033 provides that the distributions legislation does not apply to a payment made by an unquoted company, see CTM17507, on redeeming or purchasing its own shares. The effect is that the vendor is treated as receiving a capital receipt. However, if the vendor is a share dealer the receipt will still be trading income. Clearance applications under CTA10/S1044 are the responsibility of the Clearance and Counteraction Team, see below. The clearance procedure is inten

Where a company buys its own shares from trustees the distribution is treated as income. That income is chargeable at the dividend trust rate, with a credit at the dividend ordinary rate. The chargeable income excludes any amount treated as the income of the settlor, or arising under a charitable trust, or from investments, deposits or other property held for retirement benefits or pension scheme trusts. Changes were made to ICTA/S686A in FA 2006 that incorrectly charged the trustees to tax on t
