Capital gains on transfer of shares 2023/2024

I've recently transferred shares over to my unmarried partner and wanted to check if I need to pay CGT even though I did not gain any profits? If I do need to pay CGT, is it based on the date I transferred the shares and the market value of the shares on that day?

Hi 

There is no capital gains tax liability on the transfer of assets between spouses and civil partners.  As you transferred the shares to your un-married partner, you will be subject to capital gains tax on their disposal.  
You would need to obtain the market value of the shares when you disposed of them to your partner.  
You would deduct from this, you acquisition costs such as buying cost and broker fees and yoru disposal costs such as brokers fees.  If the remainder is a positive number, there is a gain chargeable to tax.  
If you have not used your annual exempt allowance, this can be set against the gain.  If there is a positive figure, you have capital gains tax to pay.  
You either report and pay this tax using the realtime capital gains service (RTTCGT) at Report and pay your Capital Gains Tax, before 31 December after the tax year ended or in a self assessment tax return.

Thank you
