We have put together this helpful guide to outline the information and supporting documents required in order to calculate any Capital Gains Tax (CGT) due for a 60 day disclosure following the sale of property (this only applies to UK property sales).
HMRC specifically requires the acquisition date and value, together with relevant buying costs for the purpose of the CGT calculation.
This is particularly important if the property was owned for several years. You will need to gather invoices/receipts for qualifying improvements, such as:
Normal repairs and maintenance costs are generally not deductible as capital improvement costs. However, qualifying improvement
expenditure may be deductible when calculating your capital gain, in accordance with HMRC guidance.
For each period of ownership, you will need to confirm:
This information is important because Private Residence Relief and, where applicable, Letting Relief may significantly reduce the amount of gain subject to Capital Gains Tax.
The following will also need to be provided:
This above is important because the rate of CGT you pay may depend on how much of your basic-rate tax band remains after
taking your taxable income into account.
We’ve put together a downloadable PDF version of this checklist, which you can save and refer back to when gathering your documents.
