Payroll — United Kingdom
Identify the applicable country, tax period, income type and filing circumstances before comparing amounts. National reference components are explicitly distinguished from manually entered local rates or unsupported rules. This directory groups payroll tools for United Kingdom; individual pages state their supported inputs and limitations.
Start with these tools
Paycheck Planning Calculator — United Kingdom
Estimate ordinary employment take-home pay from dated country tax and contribution rules. Canada, UK and Ireland use the selected supported contribution class; the national US view requires an explicit verified payroll amount. GBP planning view; stated limitations apply.
Self-employment Contribution Calculator — United Kingdom
Estimate ordinary US self-employment contributions, UK Class 4/voluntary Class 2, or Irish annual self-assessed Class S PRSI. Income tax, USC, capital gains and special exemptions are separate. GBP planning view; stated limitations apply.
Contractor versus Employee Offer Calculator — United Kingdom
Translate an employee compensation package into a contractor fee target using realistic billable time, without deciding legal employment status. GBP planning view; stated limitations apply.
Open a tool, check the displayed formula and enter values from the same period and measurement system. Currency defaults to GBP. Where a form offers metric and imperial units, changing the selector converts the entered measurements rather than relabeling the same number. Dated reference components are shown with their sources; unverified rules and prices are not silently treated as current local facts. Save distinct assumptions as separate scenarios and compare their inputs before their outputs. Shared links can disclose the input values they contain. The implemented expansion is still subject to its published scope-acceptance checks, including missing regional datasets and production-browser verification.

Frequently asked questions
Does this directory imply full local-rule coverage?
No. Each calculator states its scope. An implemented mathematical worksheet is not the same as a fully researched statutory calculator.
Where do the amounts come from?
Either your inputs or an explicitly named and dated reference component. Illustrative defaults are not supplier quotes or market averages.
Can I compare assumptions?
Use the individual calculator’s scenario controls. Read its formula, period, units and limitations before comparing results.
