Frequently asked questions

What does a Capital Gains Tax accountant in Thames do?

A Capital Gains Tax accountant in Thames helps you calculate and report gains from selling assets such as property or shares. They ensure compliance with HMRC rules, identify available reliefs, and complete the necessary sections of your Self Assessment tax return to minimise your tax liability.

Do I need to pay Capital Gains Tax on selling my main home in Thames?

What records should I keep for Capital Gains Tax purposes in Thames?

Keep records of the purchase price, sale price, costs of improvements, and any expenses related to the sale. Also retain documents showing dates of ownership and evidence of reliefs claimed. An ACCA or ICAEW accountant in Thames can help you organise these records for HMRC.

Can a Thames accountant help with both Capital Gains Tax and Inheritance Tax?

Yes, many accountants in Thames specialise in both areas. They can advise on how asset disposals affect your estate and help structure your affairs to reduce overall tax liabilities. This integrated approach ensures your financial planning is coherent and compliant with HMRC regulations.

How often do I need to report Capital Gains to HMRC from Thames?

You must report Capital Gains on your Self Assessment tax return each year if your total gains exceed the annual exempt amount. For residential property sales, you may need to report and pay within 60 days. An accountant in Thames can manage these deadlines and submissions for you.
