The tax position when you sell your estate or letting agency is one of the most important variables in assessing the economic value of any offer. Two sellers receiving identical headline prices can end up with materially different after-tax proceeds depending on how the transaction is structured, their personal tax position, and whether they have taken the right advice at the right stage.
This guide explains the key tax considerations for estate and letting agency sellers in the UK. It is designed to help you understand the framework before engaging your accountant — not to substitute for specialist advice.
Share Sale vs. Asset Sale: The Structural Decision
The most consequential tax decision is made at the structuring stage, often before most sellers have thought seriously about tax.
Share Sale
If your estate or letting agency operates through a limited company, you can sell your shares in that company. The buyer acquires the legal entity — its assets, lettings book, management agreements, brand, staff, and liabilities.
Tax treatment: The gain on your shares is subject to Capital Gains Tax (CGT). With Business Asset Disposal Relief (BADR), the rate on qualifying gains is reduced to 18% for higher-rate taxpayers — significantly lower than the standard 24% CGT rate or income tax rates on dividends.
Asset Sale
In an asset sale, your company sells its assets to the buyer — the lettings book (management agreements), the brand, goodwill, equipment, and any other assets included in the deal. You then need to extract the proceeds from your company.
Tax treatment: Your company pays Corporation Tax on the gain (currently 25% for companies with profits above £250,000). When you then extract those proceeds from the company, you pay additional tax — income tax on salary, or dividend tax on dividends up to 39.35%. The combined effective rate is typically significantly higher than CGT rates available in a qualifying share sale.
Which Structure Is Used?
In most estate and letting agency sales, the buyer has a preference. Individual buyers often prefer share sales (simpler — they inherit everything as a going concern). Corporate acquirers sometimes prefer asset purchases (cleaner liability position, step-up in asset base). The negotiation over structure is commercial and affects both parties’ tax positions.
Critically: accept the structure proposed in heads of terms only after your accountant has modelled the after-tax proceeds for both scenarios. The tax difference can be material — sometimes more than the difference between two competing offers.
Capital Gains Tax: The Basics
CGT applies to the gain when you dispose of shares or assets. For a lettings or estate agency principal:
- Gain = Proceeds − Base Cost
- Base cost = what you paid for the shares or the assets originally, plus qualifying capital expenditure
If you built the business from scratch or paid a modest amount for shares when you incorporated, your base cost may be low and the entire consideration is essentially a gain.
Current CGT Rates (2026/27)
- Basic rate taxpayer: 18% on gains (from 30 October 2024 Budget)
- Higher/additional rate: 24% on gains (from 30 October 2024 Budget)
- With BADR: 18% on qualifying gains up to the £1,000,000 lifetime limit (from 6 April 2026)
Note: the BADR rate has increased significantly from the historic 10% — it was 10% until April 2025, 14% in 2025/26, and is 18% from 6 April 2026. For higher-rate taxpayers, BADR still provides a 6 percentage point saving versus the standard 24% rate. On a £600,000 gain, that is a tax difference of £36,000 (18% = £108,000 vs 24% = £144,000) — which is why BADR eligibility is still worth significant professional attention.
Business Asset Disposal Relief for Estate and Letting Agency Sellers
BADR (formerly Entrepreneurs’ Relief) reduces CGT to 18% (from April 2026) on qualifying business disposals. The main qualifying conditions for estate and letting agency owners:
- Trading business: Your agency must be a trading business (this includes estate agency, lettings agency, and property management where the primary activity is provision of services, not investment in property)
- Ownership duration: You must have owned at least 5% of the ordinary shares for at least 2 years ending on the date of disposal
- Employment condition: You must have been an officer or employee of the company throughout that 2-year period
- Lifetime limit: £1,000,000 cumulative qualifying gains
Important: The definition of “trading” is crucial. Pure property investment companies do not qualify. Lettings agencies that manage properties on behalf of landlords are service businesses and do generally qualify — but mixed businesses (an agency that also directly owns investment property) need careful analysis.
Planning point: If you are considering a sale in the next 2–3 years and there is any question over your BADR eligibility — business structure, shareholding percentage, length of employment — address this now. Restructuring a few years before the intended sale date can restore or protect eligibility.
The Lettings Book: What It Is and How It Is Taxed
The lettings book — the portfolio of managed properties under contract — is the most valuable asset in most letting agency sales. For tax purposes:
In a share sale, the lettings book is an asset of the company. The entire consideration for the shares reflects all the assets including the book, and CGT is calculated on the total share gain.
In an asset sale, the lettings book (management agreement portfolio) will be valued and the sale proceeds allocated across the assets:
- Goodwill (the brand, client relationships, trading reputation)
- Management contracts / lettings book
- Physical assets (furniture, equipment, IT)
- Restrictive covenants (the seller’s agreement not to compete)
The allocation of proceeds matters for Corporation Tax on the sale and for the buyer’s future tax position. Your accountant should negotiate the allocation carefully.
Earn-Outs: The Tax Trap to Avoid
Earn-outs — deferred consideration tied to post-completion performance — are common in estate and letting agency sales. The tax treatment of earn-outs is an area where poor structure can convert capital gains into income.
The risk: If your earn-out arrangement is structured such that the payments are conditional on your continued employment — you get paid extra only if you stay and the business performs — HMRC may treat those payments as employment income rather than deferred consideration for the sale. This converts a capital gain (potentially 18% with BADR) into a 40–45% income tax charge.
How to protect the capital treatment:
- The earn-out should be expressed as deferred consideration for the sale of the business, not as a bonus for continued services
- The payments should be contingent on business performance metrics (revenue, EBITDA, portfolio retention), not exclusively on your continued employment
- Any separate payment for your continued services post-completion (salary, management fees) should be clearly documented and separated from the earn-out element
This distinction is often tested by HMRC on estate agency earn-outs, where the seller typically remains involved in the business post-completion. Specialist tax advice before heads of terms are agreed is essential.
Associated Property and Lease Considerations
Office Premises
If you own the freehold of your office premises and include it in the transaction, the disposal of the property is a separate capital gains event. CGT applies to the gain on the property. BADR may apply to the property if it is being sold with (not separately from) the business — but this requires careful structuring.
If your lease is assigned to the buyer as part of the transaction, there is no capital disposal of the lease itself by you — the assignment is handled through the lease documentation. However, any lease premium received could have tax implications.
Goodwill
Goodwill is a capital asset. The gain on the disposal of goodwill in an asset sale is taxed as a capital gain in the company (at Corporation Tax rates). In a share sale, the goodwill’s value is embedded in the share price and the CGT calculation is on the shares.
Timing of Tax Payments
Capital Gains Tax on the disposal of shares or business assets (other than residential property) is due on 31 January following the end of the tax year in which the disposal takes place.
For practical planning:
- Sale completes November 2026 (tax year 2026/27) → CGT due 31 January 2028
- Sale completes May 2026 (tax year 2026/27) → CGT due 31 January 2028
- Sale completes April 2027 (tax year 2027/28) → CGT due 31 January 2029
You will receive the sale proceeds at or shortly after completion but will not pay CGT until the following January. This creates a window for planning but also a significant future liability to account for in your post-sale finances.
Key Questions to Discuss with Your Accountant
Before heads of terms, ask your accountant:
- Is my business BADR-eligible? What are the qualifying conditions and do I satisfy them?
- How much of my BADR lifetime limit remains? Have previous disposals used part of the £1,000,000 allowance?
- What is the after-tax proceeds comparison for share sale vs. asset sale? Model both for any specific offer.
- How is the earn-out structured for tax purposes? Is the deferred element capital or income?
- Does the property position need any restructuring? Is the office lease or freehold included or excluded from the business sale?
- What is my estimated CGT payment and when is it due? Build this into post-sale financial planning.

Make Pension Contributions While You Still Have Earned Income
The annual pension allowance is £60,000. You can carry forward unused allowance from the three preceding tax years — potentially contributing up to £240,000 in a single year if you have not maximised contributions in those years.
Pension contributions must be backed by earned income. Once you have sold the business, your director’s salary and any other agency-derived earnings will stop. The window for making large, tax-relieved pension contributions closes at that point.
Timing matters. If you can see a sale coming in 12–24 months, the years leading up to exit are the time to maximise contributions. A £60,000 pension contribution made in a year when you are earning a director’s salary reduces your taxable income by £60,000. Made after the sale, when you may have no earned income against which to claim relief, the contribution is limited to your actual earnings in that year — potentially nothing.
SIPP flexibility. A Self-Invested Personal Pension allows contributions to be invested across a wide range of assets. Contributing to a SIPP before exit and investing the proceeds is often more tax-efficient than paying the same money as a dividend and reinvesting the after-tax amount.

Frequently Asked Questions
How much CGT do I pay when selling my estate agency?
It depends on deal structure and eligibility. In a qualifying share sale with Business Asset Disposal Relief, CGT is 18% on gains up to the £1,000,000 lifetime limit (from April 2026). Above the limit, gains are taxed at 18% (basic rate) or 24% (higher/additional rate). Asset sales involve Corporation Tax on company gains plus personal tax on extracting proceeds — typically a higher combined effective rate.
Can I use Business Asset Disposal Relief when selling my lettings agency?
Most lettings agency owner-managers qualify: you need to have owned at least 5% of the company shares, been an officer or employee for 2+ years, and the business must be a trading business. Letting agencies that manage properties on behalf of landlords are service businesses and generally qualify. Businesses with significant investment property assets need specialist analysis. The lifetime limit is £1,000,000 cumulative qualifying gains.
Are earn-out payments from selling my estate agency taxed as capital or income?
This depends on how the earn-out is structured. Earn-out payments that are conditional on your continued employment may be treated by HMRC as income (taxed at up to 45%) rather than capital gain (18% with BADR). To protect capital treatment, earn-out payments should be expressed as deferred consideration for the business sale, not as remuneration for continued services. Specialist advice before heads of terms is essential.
What is the BADR rate in 2026?
From 6 April 2026, the BADR rate is 18% — up from 14% in 2025/26 and 10% before April 2025. It applies to qualifying gains up to the £1 million lifetime limit. For higher-rate taxpayers, BADR saves 6 percentage points compared to the standard 24% CGT rate.
When do I pay CGT after selling my estate agency?
For disposals of shares or business assets (other than residential property), CGT is due on 31 January following the end of the tax year. If you complete in the 2026/27 tax year (to 5 April 2027), CGT is due 31 January 2028. Plan for this payment in your post-sale financial projections.
