How accurate are these?
Accurate enough to make a decision about whether to pick up the phone, and not a substitute for advice on your own circumstances.
Every calculator here runs on the same set of 2026/27 rates and thresholds, kept in one file so they cannot drift apart. Each one tells you exactly what it has assumed and what it has left out: pensions, student loans, Scottish rates, benefits in kind and so on.
Tax depends on details a calculator cannot see. If a result matters to a decision you are about to make, ring us on 0800 002 5226 and we will check it properly, free, in about fifteen minutes.
