Benefits & tax
UK benefits and tax rules are dense — but understanding them is often worth thousands of pounds a year. This guide explains the system in plain English and points you to free, official calculators.

Universal Credit
Universal Credit (UC) has replaced the legacy benefits for most working-age claimants. It's paid monthly and tapers as you earn — for every £1 of net earnings above your work allowance, your UC reduces by 55p.
You can claim UC whether you're in or out of work, as long as your income and savings are below the thresholds. Savings above £6,000 reduce the award; above £16,000 you usually can't claim.
Tax codes — the most common mistake
Your tax code tells your employer how much tax-free pay you're entitled to. The standard code for 2026/27 is 1257L — meaning a £12,570 personal allowance. Common reasons for a wrong code include having two jobs, recently retiring, or HMRC carrying forward an old benefit-in-kind.
Check your code on your payslip, in your Personal Tax Account or on the HMRC app. If it's wrong, you may have overpaid tax for years — reclaim through HMRC.
Marriage Allowance
If one partner earns under £12,570 and the other is a basic-rate taxpayer, the lower earner can transfer £1,260 of their personal allowance — saving the couple up to £252 a year. You can backdate four tax years. Free to apply at gov.uk.
Council Tax support and reductions
Council Tax Reduction is administered by your local council and can cut your bill by up to 100% depending on income. A single-adult household also gets a 25% discount automatically — never pay full Council Tax if you live alone.
Severely Mentally Impaired (SMI) discounts can wipe up to 100% off the bill for households where a resident has a qualifying condition such as advanced dementia. It's often missed; ask your council.
Free entitlements people miss
Pension Credit unlocks free TV licences over 75, cold-weather payments, council tax reductions and more — yet a third of eligible pensioners don't claim. Healthy Start vouchers, free school meals, Warm Home Discount, and the Household Support Fund are similarly under-claimed. Use the free benefits calculator at entitledto.co.uk or Turn2us.
Personal Independence Payment (PIP)
PIP helps with extra costs caused by long-term health conditions or disability. It's not means-tested and not affected by savings or earnings — it depends entirely on how the condition affects daily living and mobility. There are two parts (Daily Living and Mobility), each at a standard or enhanced rate.
PIP can also unlock other benefits: extra Universal Credit, Council Tax reductions, Carer's Allowance for someone who looks after you, and a Blue Badge. The application is long; charities like Citizens Advice and Scope offer free help to fill it in.
Carer's Allowance and Carer's Credit
Carer's Allowance is £83.30/week (2025/26) if you care for someone for at least 35 hours a week and they receive certain disability benefits. The earnings limit is £196/week (net) after allowable expenses. It counts as taxable income and overlaps with other benefits — so it's worth running a benefits calculation before claiming.
If you don't qualify for Carer's Allowance (e.g. you earn too much), Carer's Credit is a National Insurance credit that protects your State Pension entitlement while you provide 20+ hours of care a week. Free and easy to apply at gov.uk.
Migrating from legacy benefits to Universal Credit
If you receive tax credits, Housing Benefit, income-based JSA, income-related ESA or Income Support, you'll get a 'Migration Notice' inviting you to claim Universal Credit. You have 3 months from the letter to claim, otherwise legacy benefits stop. Managed migration is scheduled to complete by March 2026.
Most people are better off after migration thanks to Transitional Protection — a top-up that ensures you don't lose money at the point of switching. But it erodes over time as UC rates rise. Get a free benefits check before claiming, especially if you have savings between £6,000 and £16,000 or you're on legacy ESA Severe Disability Premium.
Tax-Free Childcare and 30 hours free childcare
Tax-Free Childcare gives working parents a 20% top-up on childcare costs (up to £2,000/child/year, or £4,000 for disabled children) — pay £8 in, the government adds £2, and you pay your registered childcare provider from the account. Open through gov.uk.
From September 2025, working parents in England get 30 hours per week of free childcare for children from age 9 months to school age (term-time only). Wales, Scotland and NI have their own schemes with different age and hour limits. The two schemes can be combined.

The £100,000 tax trap — and how to escape it
Earn between £100,000 and £125,140 and your effective marginal tax rate is around 60% — the highest band most workers will ever face. Pension contributions and salary sacrifice can pull you back below the trigger.

Since April 2024 the High Income Child Benefit Charge starts at £60,000 (up from £50,000) and tapers to 100% by £80,000. The charge is based on the higher earner's income, not joint income.
Read the explainer →Universal Credit — what it is and how it's calculated
Universal Credit replaced six older means-tested benefits with a single monthly payment. It is for people on a low income or out of work, and it tops up earnings as income falls.
Read the explainer →Personal Independence Payment (PIP) — the basics
PIP is a non-means-tested, tax-free benefit for working-age people with a long-term health condition or disability that affects daily living or mobility. It has a daily living component and a mobility component, each paid at a standard or enhanced rate.
Read the explainer →Marriage Allowance — transferring £1,260 of tax-free allowance
Marriage Allowance lets one partner transfer £1,260 of their unused Personal Allowance to the other, saving up to £252 a year in tax. It is worth claiming if one of you earns under £12,570 and the other is a basic-rate taxpayer.
Read the explainer →Inheritance Tax: nil-rate bands, the 7-year rule and gifts
Inheritance Tax (IHT) is charged at 40% on the value of an estate above the available nil-rate bands. Most estates pay no IHT at all — but the rules are intricate, and large gifts, second homes and pensions can all change the calculation. This guide explains the main allowances, the 7-year rule on gifts, and the major change coming in April 2027 when most unused pensions are brought into IHT.
Read the explainer →Inheritance Tax on crypto, NFTs and DeFi holdings
HMRC treats cryptoassets as property for tax purposes. That means they form part of your estate on death, are valued at their market price at the date of death, and use up your nil-rate band like any other asset. There are no special crypto allowances — but there are several practical complications around valuation, location ('situs') and DeFi positions that don't fit cleanly into the existing rules.
Read the explainer →Donating crypto to UK charities: what tax relief actually applies
Donating appreciated cryptoassets directly to a UK charity is more tax-efficient than selling them and donating the cash — but the headline often gets oversold. UK donors get CGT relief, not Income Tax relief, on a direct crypto gift. This guide sets out exactly which reliefs apply, where the s431 ITA 2007 'qualifying investment' rule fits in, and how charities can accept cryptoassets in practice.

Common questions
- Will claiming benefits affect my immigration status?
- If you have leave to remain with a 'no recourse to public funds' condition, claiming most benefits can breach your visa. Get free advice from Citizens Advice before claiming — they have specialist immigration teams.
- Do I need to file a tax return if I'm employed?
- Usually not — PAYE handles most employees' tax. You typically need to file if you have untaxed side income over £1,000 (the trading allowance), rental income to declare, are a company director with untaxed income, need to repay High Income Child Benefit Charge, or claim certain reliefs. HMRC removed the old high-earner-only trigger, so a high salary on PAYE alone no longer forces Self Assessment — but HMRC will still write to you if they want a return.
- What is the High Income Child Benefit Charge?
- Once one partner earns over £60,000, Child Benefit is gradually clawed back via the tax system, fully ending at £80,000. You can still claim — and should, to protect your National Insurance record — but you'll repay it through Self Assessment.
- How do I reclaim overpaid tax?
- If you're employed under PAYE, HMRC usually reconciles your tax automatically after the end of the tax year and sends a P800 if you've overpaid. You can also check anytime through your Personal Tax Account at gov.uk. For overpayments from previous years, you can claim back up to 4 tax years.
- Do I have to pay tax on second job or side income?
- Yes, on income above the £1,000 trading allowance (or £1,000 property allowance for casual rentals). If you have a side hustle earning over £1,000/year you usually need to register for Self Assessment by 5 October following the end of the tax year. From 2024/25, online marketplaces (Vinted, Etsy, eBay, Airbnb) report seller earnings to HMRC — but reporting doesn't equal taxable, and most casual sellers stay under the £1,000 allowance.
- Is Pension Credit really worth claiming for small amounts?
- Yes — even £1 a week of Pension Credit can be a 'gateway' to free TV licence (over 75), council tax reduction, Cold Weather Payments, Warm Home Discount, NHS dental treatment and help with glasses. The total value of the linked benefits often dwarfs the Pension Credit itself. Use the free Pension Credit calculator at gov.uk.
- How does Scottish income tax differ?
- Scotland has six income tax bands rather than three, with a Starter Rate (19%), Basic (20%), Intermediate (21%), Higher (42%), Advanced (45%) and Top (48%). The thresholds and rates change each year — see gov.scot for current figures. Welsh income tax rates currently match the rest of the UK but Wales sets its own rates within UK bands.
