Frozen for 2026/27.\n- **CGT rates after October 2024 Budget**: 18% basic rate / 24% higher rate (was 10% / 20% prior). Residential property already at these levels.\n- **Carried interest reform** in progress — proposed changes targeting fund managers' carry; details continue to evolve.\n- **Carry-forward of capital losses** still uncapped, indefinitely usable against future gains — this remains a powerful tool.\n\n## How CGT actually works\n\nYou pay CGT only when you realize a gain (sell, gift, transfer outside spouse). Each tax year (April–April):\n1. Sum all gains and losses on chargeable assets\n2. Subtract any losses brought forward from prior years\n3. Subtract the £3,000 annual exempt amount\n4. Apply the rate based on your income tax band:\n   - Below higher-rate threshold: 18%\n   - Above: 24%\n\nFor residential property (other than primary residence), same rates apply post-2024.\n\n## Tactics that reduce CGT — legitimate planning\n\n### 1. Use the annual allowance every year\n\nThe £3,000 doesn't carry forward. If your portfolio has unrealized gains, sell enough each year to crystallize £3,000 of gain into the exempt bucket. Buy back in an ISA the next day (Bed and ISA) or rebuy a similar but not identical asset (avoiding the 30-day \"bed and breakfasting\" rule).\n\n### 2. Bed and ISA\n\nSell shares in your General Investment Account, immediately rebuy them inside your ISA (using ISA allowance). The sale realizes a CGT event (£3,000 covered, anything more taxable), but future gains and dividends are inside the ISA wrapper. Over years, this migrates a taxable portfolio into a tax-free wrapper.\n\n### 3. Spouse transfers\n\nTransfers between spouses (or civil partners living together) are CGT-exempt. Effectively, a couple has £6,000 of annual allowance combined. If one spouse is in basic rate and the other higher rate, transferring assets to the basic-rate spouse before sale lowers the rate from 24% to 18%.\n\n### 4. Loss harvesting\n\nSell losers to crystallize losses, which offset gains. Realised losses set against gains in the same year first; excess carried forward indefinitely. Watch the 30-day rule: don't rebuy the identical asset within 30 days of selling for a loss, or HMRC matches the trades and disallows the loss.\n\n### 5. Use ISA / SIPP for tax-free growth\n\nFuture gains inside an ISA or SIPP don't trigger CGT. The fastest way to escape CGT is to maximise tax-wrapped contributions every year (£20k ISA + SIPP allowance).\n\n## Comparison: tax on £20,000 gain\n\nDifferent scenarios for a basic-rate-band higher-rate taxpayer realising a £20,000 gain:\n\n| Scenario | Taxable | CGT |\n| --- | --- | --- |\n| Outside any wrapper, no allowance used | £17,000 | £4,080 (24%) |\n| Used £3k allowance | £17,000 | £4,080 |\n| Spouse split (£10k each), both used allowance | £14,000 | £3,360 (24% on £14k) |\n| Spouse in basic rate (lower band) | £14,000 | £2,520 (18%) |\n| Inside ISA | £0 | £0 |\n\n## Property-specific CGT\n\nResidential property (not your main residence):\n- Same 18%/24% rates\n- Letting relief abolished except for owners who shared the property\n- Principal Private Residence (PPR) relief still available for periods you lived in it\n\nIf you own a buy-to-let, the gain at sale can be material. Plan exit years deliberately — selling across two tax years can use both annual allowances.\n\n## What to skip\n\n- **Holding gains \"for the long term\" without using annual allowance** — you're throwing away £3,000 of allowance per person per year.\n- **Assuming losses are useless** — even small realized losses offset future gains. Track them year-by-year.\n- **Forgetting the 30-day rule** — it catches more retail investors than expected; HMRC matches sells and rebuys mechanically.\n\n## FAQ\n\n**Do I pay CGT if my gain is under £3,000?**\nNo — you don't pay CGT, but if you've also disposed of assets totalling more than 4x the annual allowance (£12,000) you must report the disposals on Self Assessment regardless.\n\n**Are ETFs and unit trusts taxed the same way as individual shares?**\nGenerally yes. Watch for \"non-reporting\" offshore funds, which can be taxed as income at higher rates. Reporting funds (most major UCITS ETFs are reporting) get standard CGT treatment.\n\n**Can I gift assets to my children to use their allowances?**\nGifts are CGT events for you (treated as disposal at market value). Children under 18 have their own annual allowance, but holding accounts for minors creates tax complexity. Use Junior ISAs for tax-efficient saving for kids.\n\n## Where to go next\n\nFor related guides see [ISA vs SIPP UK in 2026](/blog/isa-vs-sipp-uk-2026), [Best UK investment apps for 2026](/blog/best-uk-investment-apps-2026), and [Crypto tax reporting guide for 2026](/blog/crypto-tax-reporting-guide-2026).","hue":304,"metaTitle":"Capital Gains Tax UK 2026: Rates + How to Reduce","metaDescription":"UK capital gains tax in 2026 — current rates, reduced £3k allowance, and the legal tactics (Bed & ISA, spouse transfers, loss carry-forward) to reduce CGT.","keywords":["capital gains tax uk 2026","cgt allowance 2026","cgt rate 2026","bed and isa","cgt loss carry forward","spouse transfer cgt","cgt on shares","cgt on property","cgt residential rate","reduce cgt bill"],"tldr":["**CGT annual allowance is £3,000 in 2026** — down from £12,300 in 2022.
