Property, shares and business disposals
Capital Gains Tax accountant in Cardiff
We calculate and report gains on property, shares, cryptoassets, business assets, gifts and other disposals using the acquisition history and evidence behind the transaction.
Before reporting or completing a sale
When a Capital Gains Tax calculation needs careful review
The sale price alone does not establish the gain. Transfers for less than market value, gifts and transactions with connected people can also be disposals for tax purposes.
Buy-to-let and second homes
Purchase costs, capital improvements, ownership shares and the residential-property reporting deadline must be checked.
A former main residence
Private Residence Relief depends on actual occupation, absences, letting history, ownership and the rules applying to the period.
Shares and investment portfolios
Same-day and 30-day matching rules, pooled costs, reorganisations and losses can change the computation.
Cryptoasset transactions
Sales, exchanges, purchases using tokens and certain gifts can be disposals even when no sterling was withdrawn.
Business assets and company shares
Eligibility for business reliefs depends on the asset, company activity, ownership period and circumstances of disposal.
Gifts, inheritance and connected parties
Market value, probate value and possible hold-over treatment require evidence; no cash received does not necessarily mean no gain.
Building the computation
How a chargeable gain is worked out
We start with the disposal proceeds or the value required by the tax rules. Allowable acquisition and disposal costs are then identified, with capital improvements separated from repairs and ordinary ownership costs.
Reliefs, current-year losses, brought-forward losses and the annual exempt amount are applied in the correct order. The applicable rate then depends on the tax year, asset type, taxable income and any qualifying business relief.
UK residential property
A property disposal may need reporting within 60 days
Where UK residential property creates Capital Gains Tax to pay, the property return and payment are generally due within 60 days of completion. The transaction may also need to appear on the Self Assessment return for the same tax year.
A non-UK resident normally reports a disposal of UK land or property even when no tax is payable. The residence position and exact completion date should be established immediately.
Do not wait for the annual return
The annual Self Assessment deadline does not replace the separate property reporting deadline. A reasonable estimate may be needed where the full year’s income is not yet known.
Evidence
Records needed for a defensible Capital Gains Tax calculation
The useful file is a chronology supported by documents, not simply a total of money spent.
Acquisition
Contract, completion statement, legal fees, Stamp Duty Land Tax or original share and asset records.
Ownership and use
Ownership changes, occupation dates, rental periods, elections, transfers and business use.
Capital expenditure
Invoices, descriptions and dates showing an enduring improvement still reflected in the asset at disposal.
Disposal and other gains
Sale statement, agent and legal costs, income estimate, other disposals, losses and earlier claims.
Cardiff property and business disposals
The local sale often carries a much longer tax history
A property may have moved from home to rental use, been owned jointly or undergone substantial work. A business owner may have reorganised shares or extracted value before a sale. Those earlier events are often more important than the completion statement alone.
We reconstruct the relevant history before calculating the gain, then keep the property report, Self Assessment return and supporting schedule consistent.

Common questions
Questions about capital gains tax calculation and reporting
The answer can change with the period, records and connected transactions. These are the usual starting points.
Do I pay Capital Gains Tax when I sell my home?
A full exemption may apply when the conditions for Private Residence Relief are met. Letting, business use, absence, land size and periods before or after occupation can alter the result.
Can repair costs reduce a property gain?
Ordinary repairs are not normally enhancement expenditure for the gain, although they may be relevant to rental income. Capital work must meet the specific enhancement conditions and be evidenced.
What if I cannot find the original purchase records?
The acquisition history still has to be reconstructed using available legal papers, bank evidence, Land Registry information, professional records or an appropriate valuation where the law permits.
Does gifting an asset avoid Capital Gains Tax?
Not necessarily. A gift can be treated as a disposal at market value, although specific exemptions or hold-over relief may apply in qualifying circumstances.
Do you file both the property return and Self Assessment return?
Yes, where included in the agreed scope. The reports are separate but must use consistent disposal figures and payment information.
