How often are the calculators updated with new tax rates?

Every Salneto calculator is updated from official published rules before each new tax year and tested against automated fixtures before any update goes live.

Do the calculators show both employee and employer costs?

Yes, employer contributions such as National Insurance and social insurance are shown for information on most calculators alongside the employee figures.

What does the annual-liability view mean?

The annual-liability view shows what you owe for the full tax year based on published brackets, rather than per-paycheck withholding which differs and reconciles at filing time.

How Salneto calculates

Salary calculators disagree with each other more than most people expect, for the same input, published results across popular sites can differ by thousands per year. Our answer is radical transparency: every engine is built from the official published rules, and every page below lists the exact figures, legal sources and assumptions we use.

Our rules

Official sources only. Rates come from the tax authority or the law itself, never copied from commercial calculators; official calculators (ESTV, BMF) are used as references.
Automated tests. Every engine ships with a test suite of hand-verified fixtures that must pass before any update goes live.
Stated assumptions. Every result lists the assumptions that produced it, and our after-tax, hourly and most guide pages show their last-updated date.
No advice. Salneto is general information, not tax advice. For decisions, confirm with the authority or a qualified adviser.
