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. See our PIP guide for the points system, assessment process and 2026/27 rates.
Carer's Allowance and Carer's Credit
Carer's Allowance is paid if you care for someone for at least 35 hours a week and they receive certain disability benefits. The earnings limit is uprated each April — check gov.uk for the current weekly cap after tax and NI. It counts as taxable income and overlaps with other benefits — run a benefits calculation before claiming.
If you don't qualify for Carer's Allowance (e.g. you earn too much), Carer's Credit protects your State Pension record while you provide 20+ hours of care a week. Our Carer's Allowance guide explains overlaps, underlying entitlement and how to apply.
Attendance Allowance (over State Pension age)
Attendance Allowance is tax-free, not means-tested, and helps with care costs after State Pension age. It can unlock Carer's Allowance for a family carer and passported help such as council tax reduction. Our Attendance Allowance guide covers rates, the AA1A form and who qualifies.
Benefits in Scotland and Wales
Scotland administers its own disability and carer benefits through Social Security Scotland — Adult Disability Payment replaces PIP, and Carer Support Payment is replacing Carer's Allowance for new claims. Universal Credit, State Pension and Pension Credit still follow UK-wide DWP rules.
Wales uses DWP for PIP and most working-age benefits but runs its own Council Tax Reduction framework and Discretionary Assistance Fund for crisis grants. Welsh undergraduates can still receive a partial maintenance grant alongside their loan.
See our Scotland and Wales benefits guides for which agency to contact, plus the regional pages on Council Tax Reduction and Adult Disability Payment.
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.
Read the explainer →High Income Child Benefit Charge — how it works after the 2024 reform
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.
Read the explainer →Council tax bands and discounts explained
Council tax pays for local services and is one of the biggest annual household bills. How much you pay depends on your property band and your council's rates — but a long list of discounts and exemptions means many people pay too much.
Read the explainer →Household Support Fund: emergency help with essentials
The Household Support Fund (HSF) is a government fund distributed to local councils to help residents facing financial hardship. Unlike Universal Credit, it is not a national scheme with uniform rules — each council decides how to allocate its share, who qualifies, and what help is available.
Read the explainer →Attendance Allowance explained: rates, eligibility and how to claim
Attendance Allowance is one of the most under-claimed UK benefits. It helps with the extra costs of disability after State Pension age — taxis, heating, a cleaner, or paying a family carer — and can unlock Carer's Allowance for someone supporting you. This guide explains who qualifies, current rates and how the AA1A claim works.
Read the explainer →Carer's Allowance explained: eligibility, earnings limit and claims
Carer's Allowance is the main benefit for unpaid carers in England, Wales and Northern Ireland. It is not generous, but it recognises caring work and can protect National Insurance credits. This guide explains who qualifies, the earnings cap, and how it interacts with other benefits.
Read the explainer →Benefits in Scotland explained: Social Security Scotland and DWP payments
If you live in Scotland, some benefits are paid by Social Security Scotland with a more claimant-centred process, while others remain administered by the Department for Work and Pensions on UK-wide rules. Knowing which agency handles your claim avoids applying to the wrong body. This guide maps the main Scottish benefits, how they differ from England and Wales, and where to get free help.
Read the explainer →Benefits in Wales explained: Welsh schemes and UK-wide payments
Wales does not have a separate disability benefit agency like Scotland. Personal Independence Payment, Universal Credit and State Pension are claimed through DWP on the same rules as England. Where Wales differs is in local welfare schemes, student finance, NHS charges and some energy-help programmes. This guide explains what is the same, what is Welsh-specific, and how to claim.
Read the explainer →Rental income tax UK explained
HMRC requires landlords to report property income through Self Assessment or Making Tax Digital when income exceeds relevant thresholds. This guide explains allowable expenses, the mortgage interest tax credit and the records you need to keep.
Read the explainer →Self Assessment expenses guide
Self-employed workers and landlords claim allowable business expenses against income on Self Assessment. HMRC allows revenue expenses but not capital items, and poor records cause rejected claims. This guide lists common categories and the evidence you need.
Read the explainer →Foreign savings tax UK explained
UK tax residents must pay tax on worldwide savings interest and declare foreign accounts on Self Assessment where required. HMRC receives data from many countries under automatic exchange rules. This guide explains reporting, allowances and double taxation relief.
Read the explainer →Tax allowances for pensioners explained
The state pension is taxable but often paid gross, with tax collected through PAYE coding on private pensions instead. This guide explains personal allowances for pensioners, how tax codes work and how to avoid silent underpayments when the state pension rises.
Read the explainer →Universal Credit changes from April 2026: what claimants need to know
Universal Credit changed materially in April 2026 — affecting family payments and disability-related amounts. Existing claimants should check their journal for updated awards; new claimants reporting health conditions need to understand the LCWRA split.
Read the explainer →Pension Credit: are you missing out on £3,000+ a year?
Pension Credit tops up low State Pension income and passport claimants to other help. It is the highest-value unclaimed benefit for pensioners — yet stigma and complexity keep take-up low.
Read the explainer →Disability Living Allowance for children explained (UK)
Disability Living Allowance (DLA) for children is being replaced by Personal Independence Payment for adults, but under-16s in England and Wales still claim DLA. Scotland uses Child Disability Payment instead. Take-up is low relative to need — many families miss this non-means-tested help.
Read the explainer →Benefits in Northern Ireland: how the system differs
Northern Ireland shares most UK welfare policy but has its own delivery body and some historical differences. Claimants near the border or moving between NI and GB need to know which rules apply.
Read the explainer →Universal Credit work allowance explained
The work allowance is one of the least understood Universal Credit rules. It determines how quickly earnings erode your award — and whether taking extra hours leaves you better off overall.
Read the explainer →Scottish Child Payment explained
Scottish Child Payment is one of Scotland's key anti-poverty benefits, administered separately from DWP. It targets families on qualifying benefits and is ignored as income for Universal Credit calculations.
Read the explainer →Discretionary Assistance Fund Wales explained
DAF is Wales-specific crisis support. Unlike Universal Credit advances, DAF grants do not normally need repaying. Each application is assessed on urgency, income and whether other help has been explored.
Read the explainer →Child Benefit explained: rates, claiming and High Income Child Benefit Charge
Child Benefit is one of DWP's highest-volume benefits but often misunderstood — many parents stop claiming when they hit the HICBC threshold without realising they can still claim and pay the charge, preserving National Insurance credits. This guide covers rates, claiming, credits and the charge.
Read the explainer →NHS prescription charges explained (England)
Prescription charging applies in England only among UK nations. Exemptions cover age, benefits, medical conditions and pregnancy. This guide explains charges, exemptions, the prepayment certificate and the NHS Low Income Scheme.
Read the explainer →Northern Ireland domestic rates: bills, rebates and reliefs explained
Domestic rates are collected by the Land & Property Services (LPS) on behalf of councils and the Northern Ireland Executive. The system differs from Council Tax in England, Scotland and Wales — banding, discounts and application routes are not interchangeable. This guide explains how bills are calculated, who qualifies for help, and how to challenge valuations.

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.
