Tax — 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 tax tools for United Kingdom; individual pages state their supported inputs and limitations.
Start with these tools

Property Transfer Tax Planner — United Kingdom
England and Northern Ireland SDLT, Scotland LBTT and Wales LTT use distinct researched schedules. Relief and surcharge eligibility must be checked first. Ireland uses researched residential, qualifying apartment-block, non-residential and bulk-acquisition schedules.

GBP planning view; stated limitations apply.
Capital Gains Tax Scenario Calculator — United Kingdom
Separate gain, taxable inclusion and tax rate. This explicit-rate scenario is not an automatic preferential-rate, stacking, indexation or recapture calculation. 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.
