HMRC Approval of Capital Gains Calculator

I wonder whether the Capital Gains calculator is approved by HMRC for making calculations of Capital Gains for shares transactions using the HMRC share identification rules for share trading activities (same day rule, 30 day rule, and section 104 pooling etc), for inclusion on tax returns ? What other software may be used for such calculations that HMRC approve for use on tax returns ? Thank you

Apologies my first question is not made clear - where it says "I wonder whether the Capital Gains calculator" the Capital Gains calculator I am referring to may be found online by searching for "CGTCalculator online capital gains calculator for UK share trades" - where there is no space between the "CGT" and the "Calculator" in the first word.

Hi Fraser Scott,
HMRC can only refer you to tools that are on gov. uk - Tax when you sell shares
Thank you.

Hi Fraser Scott,
There is only a calculator for disposal of UK residential property and land.
For all other disposals, you will need to work out the gain yourself.
Please have a look at the guidance here which explains how to do this:
Capital Gains Tax: what you pay it on, rates and allowances
Thank you. 

So can a software program be used to calculate the capital gains for share trading ? And then we submit the output from that program to HMRC with our SA108 tax return ? Or must we do it by hand and submit the calculations to HMRC ?

Hi Fraser Scott,
HMRC does not provide a calculator for working out capital gains tax arising from shares or other assets that are not residential property.  There may be commercial calculators on the internet, you could use at your own risk.  
If you find you have a capital gains tax to pay from the disposal of shares, you can report and pay the tax using the raltime capital gains tax service at Report and pay your Capital Gains Tax-to-report.  You have until 31 December after the tax year ends to do this.  After this, you must complete a self assessment tax return.
Thank you.
