How do I calculate tax on shares?

Thanks for dropping by!
I have accumulated monthly shares for 3.5 years as part of my employer's SPP. I'm unsure how much tax (if any) I need to pay after I sell.


I have accumulated monthly shares for 3.5 years as part of my employer's SPP. I'm unsure how much tax (if any) I need to pay after I sell.
- My current understanding is that if I gain more than £2K of profit per annum, I have to pay a tax. Is this correct?
- If I put in 1% of my salary, my company doubles it. And I think my company's input is also taxable.
- I currently pay 40% tax on my income.
- Now, these shares were acquired at a different time, and the value of each share is different. I'm unsure how to work out what the gain is. The figure below shows few of the shares and when the transaction had taken place, it shows the 'Amount' (including 50% paid by my company), 'Share price' how much it was, 'Transaction Shares' how many were purchased, 'if sold at 78.4201' calculates what I would have gained if I sold the shares on Jan 4th (excluding any fee I may need to pay), then the last two columns: (1) what I would have gained from each share including my company's contribution, and (2) without my company's contribution.

My questions are
Thanks
- First have I calculated this correctly? If not, how should this be done to work out how much tax I need to pay?
- Assuming the calculation is correct, If I only sell 20 of the shares, how do I work out what the profit is? If I sell them all, it isn't a problem, but part of them I'm struggling to imagine! Part of me thinks I've over complicated it 😁
Thanks

Mortgage debt start date = 25/10/2024 = 175k (5.44% interest rate, 20 year term)
Q4/2024 = 139.3k (5.19% interest rate)
Q1/2025 = 125.3k (interest rate dropped from 5.19% - 4.69%)
Q2/2025 = 109.2K (interest rate 4.44%)
Q4/2024 = 139.3k (5.19% interest rate)
Q1/2025 = 125.3k (interest rate dropped from 5.19% - 4.69%)
Q2/2025 = 109.2K (interest rate 4.44%)

First off Capital Gains tax limit is currently £12,000, so you need to make over £12,000 to pay. So I think you are fine, you don't even need to declare it, as long as you fall below this limit.1

The 2K limit is for dividend income and is a separate thing.1

Thanks, I mixed up the tax with something else then... finance is my nemesis 😁Note:I'm FTB, not an expert, all my comments are from personal experience and not a professional advice.Mortgage debt start date = 25/10/2024 = 175k (5.44% interest rate, 20 year term)

Worth spending time reading the brochure for your employer's scheme as these are often set up in a tax-efficient way anyway, as per https://www.gov.uk/tax-employee-share-schemes
https://www.gov.uk/capital-gains-tax and https://www.gov.uk/tax-sell-shares are also useful overviews of taxation in this area, if applicable....

Yeah as said above the type of scheme is important here from a tax perspective. They're all quite different in their treatment of tax and other bits, usallly all in a good way though!1

Thanks peeps for helping me save my pennies 😁👍
Thanks for your help, on the last link, i had tried to use the calculator earlier in the month, but when it asked me "How much did you pay for the shares", i stopped there and that's where this post was born from, because for the 20 shares I want to sell, i can't specify which of the shares they should be be selling (in other words, i can't say sell by oldest first, or maybe that's what they do?) so I never really understood how to workout the tax amount to see whether i hit the limit or not. 😫eskbanker said:Worth spending time reading the brochure for your employer's scheme as these are often set up in a tax-efficient way anyway, as per https : // www.gov.uk/tax-employee-share-schemes

I'll dig out the paper work to find out what type of scheme it is, i hope it is tax efficientNote:I'm FTB, not an expert, all my comments are from personal experience and not a professional advice.Mortgage debt start date = 25/10/2024 = 175k (5.44% interest rate, 20 year term)

However I’m not sure if them being in an employee share scheme changes any of that.1 -
