A quiet campaign against fiscal drag

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

UK Tax Drag is an independent, UK-based editorial project. The site is run by a small team with experience in UK financial services, supported on the more technical sections by chartered accountants and independent financial planners who fact-check before publication.

For corrections, factual errors, or editorial questions, email corrections@uktaxdrag.co.uk. For press, partnership (non-commercial), data requests, or syndication enquiries, email hello@uktaxdrag.co.uk.

Where a guide has been reviewed by a practising adviser, the page carries a "Reviewed by" line 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.

The site is funded by Google AdSense display advertising, kept on guides and hub pages and out of the calculators. Running costs are modest - about £140 a year for a domain, a Netlify plan, and a transactional email provider. Revenue comes only from that advertising - never from affiliate deals, sponsored content, or data sharing.

Where readers want a qualified UK adviser

UK Tax Drag is built to help most readers solve most tax questions themselves with calculators and explainers. Where a situation genuinely needs a qualified human - complex multi-income returns, EIS/VCT claims, IHT planning, incorporation decisions, MTD ITSA setup, HMRC disputes - we maintain a small editorial recommendations page on Find a UK tax adviser.

The firms listed on that page are listed solely on the basis of direct, long-standing personal experience by UK Tax Drag's editorial team. There is no referral fee, commission, affiliate link or other commercial relationship between UK Tax Drag and any listed firm. The list grows slowly because direct multi-year experience matters more than a comprehensive directory. The current featured firm is Maze Tax Services, an ACCA-qualified UK accountancy firm we have worked with personally for over a decade.

"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.

Editorial review

Every calculator and guide on the site is reviewed before publication and again on each tax-year change. The review process checks: rate and threshold accuracy against current HMRC bulletins, calculation logic against worked examples from primary sources, edge-case behaviour at band boundaries, accessibility (keyboard, screen-reader, contrast), and that any cited source page still exists and still says what we claim.

Corrections

We publish openly, so we get things wrong openly. If you spot a factual error — an out-of-date threshold, a broken calculation, a citation that has rotted, a miscounted decimal — please email corrections to corrections@uktaxdrag.co.uk. Substantive corrections are logged at the bottom of the affected page with a date and a short note on what was changed. We do not silently re-edit.
