Important information about the limits of what this site provides.

Educational estimates only

Every calculator on this site produces an educational estimate, not a personalised financial, tax, or legal recommendation. Results depend entirely on the assumptions you enter and on our general understanding of current HMRC rules, which may not reflect your employer's specific plan terms or your individual circumstances.

Not affiliated with HMRC

This site is independent and is not affiliated with, endorsed by, or connected to HMRC or any UK government body.

Rules can change

UK tax rules, including Share Incentive Plan limits, can change at any Budget or Finance Act. We aim to keep figures current and note a "last checked" date on relevant pages, but you should confirm your own position with your employer's SIP administrator, HMRC, or a qualified adviser before making financial decisions.

No liability

We accept no liability for decisions made based on the estimates or information provided on this site.
