How Are Vested Shares Taxed in the UK? A Guide for Employees
You log into your employee share account and there they are: shares that have just vested and now belong to you. That moment can feel electrifying and confusing at once; you own company equity, but do not assume that vesting means cash in your pocket. Generally, the act of vesting is treated as employment income, and that can trigger Income Tax and National Insurance charges on the market value at vesting. If you want the official rules on how different schemes are treated, consult the employee share scheme rules, but read on and I will walk you through the sequence: vesting, holding, selling and how to fold vested shares into your wider plan.
What are vested shares, and how is this different from selling them?
Vesting is the moment any restrictions on your employer-granted shares lift and legal ownership transfers to you; it is not the same as a sale. In many RSU-style awards the company retains the shares on your behalf until vesting, then they become yours and appear on your employee account or payroll. Selling vested shares is a separate action you must take through a broker or your employer’s share-dealing service, and that sale triggers capital events. You should check your payslip and the employee share scheme rules to see exactly when the employer values the shares for tax, because knowing the precise vesting date and market value is essential for later CGT calculations.
Vesting is just the start; understanding the tax and your broader plan is how you turn employer shares into long-term financial advantage.

How are shares taxed when they vest?
Generally, when shares vest they create an employment income event, so Income Tax and employee National Insurance Contributions apply on the market value at the point of vesting; this is typically collected through PAYE or reported on a self-assessment tax return depending on the scheme and employer arrangements. Tax treatment depends on the specific scheme, so different treatments apply for unapproved awards, SIP, CSOP and EMI. For example, shares from unapproved awards are usually taxed on full market value at vesting as employment income, whereas SIP, CSOP and EMI may offer reliefs or deferrals if their conditions are met; tax treatment depends on the specific scheme.
Key numbers to bear in mind
Your vesting income is added to other pay and can push you through thresholds. The Personal Allowance is £12,570, for the 2026/27 tax year and may change; basic rate is 20% on £12,571 to £50,270, for the 2026/27 tax year and may change; higher rate is 40% on £50,271 to £125,140, for the 2026/27 tax year and may change; additional rate is 45% above £125,140, for the 2026/27 tax year and may change. Employee National Insurance contributions apply, for example 8% and 2% bands on weekly earnings ranges, for the 2026/27 tax year and may change; employer NIC can also arise and can sometimes be passed to the employee.
Generally, vesting is taxed as employment income at the market value when restrictions lift, so expect Income Tax and NIC implications.
What happens when you sell?
When you sell vested shares you are liable for Capital Gains Tax on the growth from the vesting value to the sale price, using the market value at vesting as your cost for CGT purposes because Income Tax was generally charged on that amount at vesting. The annual CGT exempt amount is £3,000, for the 2026/27 tax year and may change, which you can deduct from gains before tax. CGT rates are 18% for basic-rate taxpayers and 24% for higher or additional-rate taxpayers on shares, for the 2026/27 tax year and may change. Be aware of the current CGT rates and allowance and that you may need to report sales via a self-assessment tax return or the HMRC real-time reporting route depending on timing and value.
Should you keep or sell your vested shares?
Deciding to keep or sell vested shares is about balancing concentration risk against potential upside; holding a large slice of your wealth in employer stock concentrates both your pay and investment risk in one company. A portfolio management approach can help you judge whether you are over-exposed to company-specific risk, and staged selling can spread CGT use across tax years to make use of the £3,000 annual exempt amount, for the 2026/27 tax year and may change. Other considerations include any insider trading rules or blackout windows at your employer, tax brackets you will occupy after vesting, and emotional attachment that can bias decision-making; these are factors to weigh rather than directives to act.
When you sell, Capital Gains Tax applies only to growth after vesting; use the annual exempt amount to reduce taxable gains.
Fitting vested shares into your wider financial plan
Vested shares can be a powerful part of your plan when you use proceeds strategically. You can sell and reinvest into tax-efficient wrappers such as an ISA, where the annual allowance is £20,000, for the 2026/27 tax year and may change, or into a pension where the annual allowance is £60,000, for the 2026/27 tax year and may change, subject to your circumstances. You cannot transfer shares directly into an ISA; you must sell first, then subscribe cash, which makes a bed-and-ISA approach useful for preserving future tax-free growth. Consider how proceeds interact with your emergency savings, mortgage goals and longer-term targets by reviewing your options on savings and investments.
Keeping good records
Accurate records make tax life far easier. Keep the acquisition date and market value at vesting, scheme documentation and any HMRC approval references, the number of shares and the exact share price shown on your payslip or P60 as confirmation of tax paid. Also retain broker sale confirmations, dates and proceeds, because your CGT calculation uses vesting value as the cost basis. Beware the HMRC 30-day matching rule which matches same-class shares bought within 30 days of a sale to that sale for CGT purposes; for reporting you may need to complete a self-assessment tax return if gains are taxable.
Holding lots of employer stock concentrates risk; consider staged selling and reinvesting into ISAs or pensions to diversify.
When is it worth getting advice?
Seek professional advice when the value of your vested shares is large relative to your net worth, for example when holdings exceed typical thresholds that could materially affect retirement, tax or estate plans, or when you hold multiple scheme types with differing tax rules. You should also consider help if a vesting event pushes you into higher or additional-rate tax bands, if you are leaving the employer and need special treatment for unvested or pro-rated awards, or if your employer is listed overseas which adds cross-border tax complexity. A qualified adviser can model outcomes and work with tax specialists to integrate share events into your financial plan; tax treatment depends on the specific scheme.

Common scheme comparisons: tax at vesting and tax on sale
| Scheme | Tax at vesting | CGT on sale |
|---|---|---|
| Unapproved / RSU-style awards | Full market value at vesting treated as employment income, Income Tax + employee NIC usually via PAYE; tax treatment depends on the specific scheme | CGT on growth from vesting value to sale price, after the annual exempt amount (£3,000, for the 2026/27 tax year and may change) |
| Share Incentive Plan (SIP) | Shares held in the plan for 5+ years are free of Income Tax and NIC on vesting value, tax treatment depends on the specific scheme | Selling from a SIP after 5 years: typically no CGT on growth during the plan period |
| Company Share Option Plan (CSOP) | No Income Tax or NIC on exercise if conditions are met; tax treatment depends on the specific scheme | CGT on growth from exercise price to sale price |
| Enterprise Management Incentive (EMI) | No Income Tax or NIC on exercise if conditions are met; tax treatment depends on the specific scheme | CGT on growth, may qualify for Business Asset Disposal Relief if qualifying conditions met |
Frequently Asked Questions
If Income Tax is deducted at vesting, do I still pay Capital Gains Tax when I sell?
Yes. Income Tax and employee NIC are generally charged on the market value at vesting, and that market value becomes your cost basis for Capital Gains Tax. When you later sell, CGT applies only to the increase above that vesting value. Remember the annual CGT exempt amount is £3,000 for the 2026/27 tax year and may change, which can shelter some or all of a small gain. Keep records of the tax already paid on vesting, because that documentation supports your CGT calculation.
Can I avoid Income Tax by waiting to sell until share prices fall?
No. Generally, Income Tax and NIC apply at vesting on the market value at that point, not at sale; delaying a sale to avoid a tax charge at vesting is not effective, because the income tax event is triggered when restrictions lift. What you can do is manage post-vesting exposure and plan sales to make the most of your CGT annual exemption, for example by spreading sales across tax years. If you have scheme-specific reliefs available, tax treatment depends on the specific scheme and professional advice can clarify options.
How does leaving my employer affect vesting tax treatment?
When you leave your employer, different rules can apply to unvested awards, pro-rated grants or accelerated vesting, and tax treatment depends on the specific scheme terms. Some schemes accelerate vesting on redundancy or change-of-control, which can create an unexpected tax bill. If you are approaching a move, check your award documentation and speak to payroll or a tax specialist to understand timing, potential PAYE collection and the interaction with any final salary or bonus payments that year.
