Frequently Asked Questions

What is an RSU tax calculator?

An RSU tax calculator estimates taxes on restricted stock units, including income tax, National Insurance, and capital gains tax when shares vest or are sold.

How are RSUs taxed in the UK?

RSUs are taxed as income when they vest, with income tax and National Insurance applied. Selling shares later may trigger capital gains tax on profits.

What tax reliefs are available for RSUs?

Schemes like EMI (30% tax relief on vesting) or CSOP (no NICs) can reduce your tax liability, depending on your employer’s plan.

Can I estimate future RSU taxes?

Yes, our calculator lets you input a projected share price to estimate future capital gains tax based on potential share sales.
