Capital Gains Tax
Advice & Planning
Wimbledon & London
The CGT annual exemption has been cut from £12,300 to £3,000 in four years. More disposals now trigger a tax liability, and the 60-day reporting deadline on residential property catches sellers out every quarter. Our ACCA-certified Wimbledon team plans your CGT position before disposal, not after.

Two Types of Capital Gains Tax Situation. Both Require Planning Before the Disposal.
Capital gains tax arises on two very different types of disposal, each with its own rates, reliefs, reporting deadlines, and planning opportunities. What they have in common is that the time to act is before exchange or completion, not after.
Property & Land Capital Gains Tax
60 days Deadline to report AND pay CGT on UK residential property after completionSelling a buy-to-let, second home, inherited property, or any residential property that is not your main residence triggers CGT. With South West London and Wimbledon property values having risen significantly, the gain on properties purchased even a decade ago can be substantial, and the 60-day reporting and payment deadline applies from the date of completion, not the end of the tax year.
We calculate the exact gain, identify every allowable deduction, apply any partial Private Residence Relief where the property was once your main home, and file the CGT return within the 60-day window. Missing this deadline triggers penalties regardless of when your self assessment return is due.
Business & Investment Capital Gains Tax
18% BADR Business Asset Disposal Relief rate from 6 April 2026 (was 10% before April 2025)Directors selling a business or shares, investors disposing of portfolios, and individuals receiving gifts of business assets all face CGT treatment that differs significantly from property. Business Asset Disposal Relief can reduce the CGT rate to 18% on qualifying disposals from April 2026, subject to a £1 million lifetime limit and specific qualifying conditions that must be met before the disposal takes place.
We review BADR eligibility, structure the transaction to preserve qualifying status, and advise on rollover and holdover relief where applicable. Crystallising a business sale without confirming BADR eligibility in advance is one of the most expensive mistakes we see.
Annual Exempt Amount: £3,000 in 2025/26 and 2026/27The CGT annual exemption has been cut from £12,300 in 2022/23 to £3,000 today, a 75% reduction in four years. Gains that previously fell within the exemption now create a real tax liability. Disposals that were planned under old assumptions should be reviewed. Spousal transfers and loss planning are more important than ever when only £3,000 of gain is tax-free each year.
Capital Gains Tax Rates: Current Rates for 2026/27
CGT rates changed significantly with the October 2024 Autumn Budget. Rates on most assets were aligned with residential property rates, and Business Asset Disposal Relief rates have stepped up annually since April 2025. We are currently in the 2026/27 tax year. BADR is now 18% (the 14% rate expired 5 April 2026). Getting the right rate applied requires knowing your taxable income in the year of disposal.
| Asset Type | Basic Rate Taxpayer | Higher / Additional Rate | Notes |
|---|---|---|---|
| Residential property (buy-to-let, second home) | 18% | 24% | 60-day reporting deadline after completion. Main residence exempt under PRR. |
| Shares, funds & other chargeable assets | 18% | 24% | Rates aligned with property from 30 October 2024. Self assessment deadline applies. |
| Business assets qualifying for BADR | 18% Current rate (from 6 Apr 2026) Was: 14% in 2025/26, 10% before Apr 2025 |
£1 million lifetime limit. Qualifying conditions must be met for 2 years before disposal. | |
| Investors’ Relief (unlisted company shares) | 18% Current rate (from Apr 2026) Was: 14% in 2025/26 |
Newly issued unlisted shares held 3+ years. £1 million lifetime limit. | |
| Annual Exempt Amount (individuals) | £3,000 2025/26 and 2026/27 | Down from £12,300 in 2022/23. Frozen at £3,000 until at least 2030. | |
| Spousal / civil partner transfer | No gain / no loss | CGT-neutral. Transfers the base cost. Both partners then have own AEA and rate band. | |

The rate you actually pay depends on your total taxable income in the year of disposal, as gains are added on top of income when determining which band applies. We calculate the exact position for your circumstances before advising on timing.
Every Type of Chargeable Disposal and CGT Relief We Advise On
Capital gains tax applies across a wider range of assets and situations than most people realise. Below is a guide to the disposals and reliefs we regularly handle for clients in Wimbledon, South West London, and across the UK.
Chargeable Disposals
Buy-to-let & residential property sales: gain calculated from purchase to sale, less allowable costs, with 60-day CGT return and payment to HMRC
Inherited property: gain calculated from probate value at date of death, not original purchase price, with specific rules around private residence relief where inherited
Business sales and share disposals: exit from a sole trader business, partnership, or limited company, including BADR eligibility review and lifetime limit tracking
Shares, funds & investment portfolios: share identification rules, bed and ISA planning, and loss harvesting strategies across a portfolio
Gifts of chargeable assets: gifts are treated as a disposal at market value for CGT purposes, with holdover relief available for business assets
Reliefs & Planning Strategies
Private Residence Relief (PRR): full or partial exemption where the property was, or has been, your main residence, including the final 9-month rule and letting period calculations
Business Asset Disposal Relief (BADR): confirming qualifying conditions are met before disposal: personal company test, officer or employee status, and 2-year holding period
Rollover and holdover relief: deferring gains on reinvestment into new qualifying business assets or gifting qualifying business interests to the next generation
Spousal transfers & annual exemption doubling: transferring assets to a spouse or civil partner before disposal to use both annual exemptions and potentially lower the applicable rate
Capital loss planning: offsetting current-year losses, carrying forward unused losses, and timing disposals across tax years to use multiple annual exemptions

Full CGT calculation for buy-to-let and residential property disposals, including all allowable purchase costs, improvement costs, and selling expenses.

Get a Quote →Business Asset Disposal Relief (BADR) Planning
We confirm BADR qualifying conditions are met before exchange: the personal company test, officer or employee status, and the 2-year ownership and activity period. The BADR rate rose to 14% from April 2025 and to 18% from April 2026. With the £1 million lifetime limit, using the allowance correctly requires careful tracking and timing, especially for directors who have made previous qualifying disposals.
Enquire Now →Pre-Disposal CGT Planning for Wimbledon & London Clients
The most valuable CGT advice is given before the sale is agreed, not after exchange. We model the full gain, identify every available relief, assess the impact of your income in the year of disposal on the rate applied, and advise on whether splitting a disposal across two tax years, transferring to a spouse first, or timing completion differently would produce a materially better outcome.
Book a CGT Review →Investment & Shares CGT
CGT on shares and investment portfolios involves share identification rules (first in first out, Section 104 pooling, bed and breakfast rules), annual exemption optimisation, and loss harvesting across a portfolio. We advise on bed and ISA strategies to shelter future gains and calculate the correct base cost for complex portfolios where shares have been acquired in tranches over many years.
Enquire Now →Inherited Property & Estate CGT
Inherited property uses the probate value at the date of death, not the original purchase price, as the base cost. This can significantly reduce the taxable gain compared to properties purchased by the deceased at original market value. We calculate the gain from probate value, identify any partial Private Residence Relief where the executor has resided in the property, and handle the 60-day return correctly.
Enquire Now →Loss Planning & Annual Exemption Optimisation
Capital losses must be claimed on a self assessment return to be recognised. Unclaimed losses from prior years are commonly missed. We identify carried-forward losses, model whether triggering losses in the current year offsets gains efficiently, and advise on spreading disposals across tax years to use multiple annual exemptions. With the AEA frozen at £3,000, every pound of loss planning and timing matters more than it did three years ago.

Wimbledon-Based CGT Advice That Starts Before You Sell
South West London property values mean most long-term owners are sitting on significant embedded gains. The reduction in the annual exemption from £12,300 to £3,000 means disposals that once produced little or no tax now trigger meaningful bills. Muhammad Bilal ACCA and the Protax team have been helping Wimbledon, SW London, and UK-wide clients plan and report CGT correctly for over 15 years, from our office at Lombard Business Park, SW19 3TZ.

01
We Advise Before Disposal, Not After Exchange
Once contracts are exchanged, your disposal date is fixed. The tax year of the gain, the rate applied, and most reliefs are determined at that point. Pre-disposal advice, which takes days, can save thousands. Post-disposal advice can only calculate what is owed, not reduce it.
-
02
The 60-Day Rule Catches Sellers Out Every Quarter
The 60-day reporting and payment deadline for residential property CGT runs from the date of legal completion, not the tax year end and not the self assessment deadline. Sellers who assume they have until 31 January the following year face automatic penalties and interest. We flag the deadline at the point of instruction and ensure the return is filed on time.
-
03
Private Residence Relief Calculations for Complex Ownership Histories
PRR is not always all-or-nothing. If a property was your main home for part of the ownership period, or was let out for part of the time, a partial exemption applies. The final 9 months of ownership always qualify. We map the full ownership history and calculate the correct PRR fraction before the gain is reported.
-
04
BADR Rate Changes Require Timing Awareness
The Business Asset Disposal Relief rate was 10% before April 2025, 14% from April 2025, and 18% from April 2026. For directors planning a business exit, the year of disposal now matters significantly to the rate applied. We model the tax cost under each scenario and advise on the most efficient timing given your commercial position.
-
05
Spousal Transfers & Loss Planning Integrated Into Every Disposal
With the annual exemption at only £3,000, using two exemptions through a spousal transfer before disposal can halve the taxable gain on the first £6,000. We check whether a spousal transfer makes sense, whether any losses can be crystallised to offset the gain, and whether staging the disposal across two tax years produces a better net outcome.

Used Protax for my first year in business. The process was so simple and smooth. I checked a few accountants before going with Muhammad and Protax. As a new business owner accountants can be a little confusing — not only did the team do a lot for me, they also taught me a lot. Will be using Protax for as long as I am in business. Highly recommend.
