The UK tax system is not complicated by accident. It is complicated because successive governments have preferred to raise money quietly — by freezing thresholds, narrowing allowances, adding surcharges — rather than by the blunter act of raising headline rates. The effect on a payslip is the same. The political cost is not.
This site was built to make those quiet tax rises visible. Every calculator here is tuned to the current tax year. Every guide explains not just the rule but the direction it is travelling in. The aim is boring: to help a person at a kitchen table in Hull, Swansea, Leeds or Peckham understand, inside five minutes, why their take-home pay has not moved the way they expected.
Who runs this
It is a one-person project for now, with occasional help from chartered accountants and independent financial planners who fact-check the more technical sections. Where a guide has been reviewed by a practising adviser, the name appears in a byline at the top. Where it has not, the page shows only the site-wide "Last reviewed" date and is flagged as editorial opinion rather than advice.
Our editorial stance
A finance site only works if you can trust it. The incentives on the modern internet are not set up to reward trust — they are set up to reward clicks, conversions and referrals. We have taken a deliberately narrow set of decisions to keep those incentives out.
What you will never find on UK Tax Drag
- No ads inside the calculator flow. If the site carries advertising, it lives in clearly marked slots on hub pages, long-form guides, or after-result helper areas - never inside calculator inputs, result panels, or scenario tools.
- No affiliate links. We do not earn commission when you click through to a broker, a pension provider, an ISA platform, a conveyancer, a mortgage broker, or any other regulated firm. The site links to providers only when there is a genuine editorial reason to, and always with a clear rel=nofollow.
- No sponsored content. No "in partnership with" articles, no gifted content, no paid placements inside calculators.
- No lead-generation. We do not sell your email, your search history, or your calculator inputs to third parties. Anything saved inside a calculator lives in your browser only - unless you explicitly opt in to the magic-link sync feature, which is a plain email to yourself.
- No invasive tracking. If analytics are used, they stay lightweight and focused on understanding which pages help people most, not on building advertising profiles or resale datasets.
The site is funded directly out of pocket. It costs about £140 a year to run: a domain, a Netlify plan, a transactional email provider. If, in the fullness of time, it needs outside funding, that support can come from carefully separated advertising on guides and hub pages - never from affiliate deals, sponsored content, or data sharing.
"Beautifully boring" is the house style. Tax is not meant to be exciting. It is meant to be understood.
How the calculators are kept accurate
Every calculator on the site is tied to a specific UK tax year. When a Budget, Spring Statement or Autumn Statement is delivered, the site is reviewed inside forty-eight hours and every calculator either confirmed unchanged or updated and re-stamped with a new "Last reviewed" date.
On top of that rolling review, each calculator gets a full top-to-bottom recheck on 6 April of each year — the first day of the new UK tax year — to pick up any quieter updates (HMRC internal manuals, new case law, FCA handbook changes) that did not make the headlines.
The full technical write-up of how each calculation is constructed — the allowances used, the bands applied, the assumptions baked in, and the source documents relied on — lives on the methodology page. Every individual calculator also lists its own sources at the foot of the page.
What UK Tax Drag is not for
Everything on this site is general information, not personal advice. It is written for the great middle of UK financial life: the PAYE employee, the modest self-assessment taxpayer, the first-time buyer, the ISA saver, the auto-enrolled pension holder, the person working out whether to sell a flat.
It is deliberately out of scope for:
- Non-domicile status and the remittance basis (retiring from 6 April 2025 under the FIG regime — the transition is specialist territory).
- Trusts (bare, interest-in-possession, discretionary, relevant property, bereaved minor's and similar vehicles).
- Business-specific reliefs of any substance — Business Asset Disposal Relief, Business Relief, Agricultural Relief, EIS, SEIS, VCTs.
- Cross-border scenarios — double-taxation treaties, split-year rules, remittance basis, offshore trust anti-avoidance.
- Scottish or Welsh devolved income tax bands, except where expressly flagged on a given calculator.
If any of those apply to you, the right move is an Institute of Chartered Accountants (ICAEW) or Chartered Institute of Taxation (CIOT) member, or a Chartered Financial Planner (CFP) with specialist experience in your area. The site will happily point you at the relevant register.
