A Renters Rights Act fine can reach £40,000 for a serious offence, with lesser breaches attracting penalties of up to £7,000 and tenants potentially able to reclaim up to two years’ rent. Yet for many landlords, the fine itself is not the biggest concern. Instead, it serves as a warning that prompts a much larger question – with regulation becoming increasingly stringent, does it still make sense to hold rental property in your own name?
This guide compares the three main paths available to landlords — selling, incorporating, or remaining as a sole owner — and examines the costs, benefits and trade-offs of each.
Key Takeaways
- The maximum Renters Rights Act fine is £40,000 for an offence and £7,000 for a breach
- Knowingly or recklessly relying on a possession ground without being entitled to do so is an offence under section 16J of the Housing Act 1988 and can also lead to a rent repayment order of up to 24 months’ rent
- If you recover possession under Ground 1A (intention to sell) and the sale subsequently falls through, you cannot re-let the property for 12 months, potentially leaving you with mortgage payments and other costs on an empty property
- Selling a rental property typically crystallises a Capital Gains Tax liability, with gains taxed at 18% or 24% and the disposal reported to HMRC within 60 days of completion
- Incorporating a property portfolio can potentially defer Capital Gains Tax and restore full mortgage interest relief, but it may also trigger SDLT and generally requires the letting activity to qualify as a genuine property business
What Is the Renters Rights Act Fine & When Does It Apply?
Under the Renters Rights Act, landlords can face penalties of up to £7,000 for a breach and up to £40,000 for a serious offence. The most significant penalties apply where a landlord misuses a possession ground to regain possession of a property.
The £40,000 penalty is particularly relevant for landlords who rely on a possession ground they are not genuinely entitled to use. Under section 16J of the Housing Act 1988, an offence may be committed if a landlord “knowingly or recklessly” claims a possession ground, the tenant leaves within four months, and no possession order has been granted by the court.
A common example is serving notice on the basis that you intend to sell the property or move a family member into it when that intention is not genuine. If the evidence suggests the ground was used simply to secure vacant possession, the landlord could face enforcement action.
The distinction between an honest mistake and an offence is important. A landlord acts recklessly when they take an unjustified risk that the possession ground they are claiming may not apply. Acting knowingly goes further and generally involves relying on a ground despite being aware that the court would be unlikely to grant possession. Whether either test is met depends on the facts of the case.
However, the financial risk does not stop with the fine itself. Where an offence is committed on or after 1 May 2026, the tenant or local authority may also apply for a rent repayment order. The First-Tier Tribunal can require the landlord to repay up to 24 months' rent, doubling the previous maximum award.
For many landlords, that repayment order represents the greatest financial exposure. A £40,000 penalty is significant, but repaying up to two years of rent on top of that can make a failed possession strategy extremely costly.
The Question After the £40K Fine: Should Landlords Stay, Sell or Incorporate?
There is no one-size-fits-all answer. The right choice depends on your rental profits, mortgage debt, future plans and potential tax liabilities.
Section 21 has gone. Every eviction now requires a valid Section 8 ground, supporting evidence and, where necessary, a court process. At the same time, landlords continue to face the effects of Section 24 mortgage interest restrictions, higher compliance requirements and additional reporting obligations.
Many landlords have decided enough is enough. Industry estimates suggest around 93,000 landlords exited the market during 2025, while the English Private Landlord Survey found that 16% of landlords intend to sell all their rental properties within the next two years.
Others have moved in the opposite direction. A record 66,587 Buy-to-Let companies were incorporated during 2025, reflecting the growing number of landlords exploring corporate ownership as a way to improve tax efficiency and regain full mortgage interest relief.
If you’re pondering a similar decision, it is important for you to understand the consequences of each route before you.
Route | Main Cost | Watch Out For |
|---|---|---|
Sell Up | CGT at 18%-24%, reportable within 60 days | Ground 1A: 12-month re-let ban if the sale falls through |
Incorporate | SDLT on transfer, CGT deferred only if reliefs apply | The “business” test; s.162 relief now needs to be claimed, not automatic |
Stay Put | Section 24 mortgage interest restrictions | MTD for Income Tax from April 2026; new property rates from 2027 |
Option 1. Sell Up & Exit the Market
Selling is the clean break, and for landlords with a single low-yield property or a looming EPC bill, it is often the rational choice. The complication is that selling with vacant possession is no longer simple.
The Ground 1A “12-Month Trap”
To recover an occupied property in order to sell, you now use Ground 1A. It requires four months’ notice, cannot be used in the first 12 months of a tenancy, and carries a restriction that catches landlords out.
The restriction is that once you have relied on Ground 1A, you cannot market the property for letting or re-let it for 12 months. Crucially, that 12-month bar runs from the date in the notice and applies whether or not the sale completes.
If you serve a Ground 1A notice, your tenant leaves, and the sale then falls through, you are left with an empty property you cannot legally re-let, while still covering the mortgage, Council Tax and insurance. Re-letting within the restricted period is itself an offence carrying the £40,000 penalty.
The Tax Cost of Selling
Selling a Buy-to-Let is a Capital Gains Tax event. For residential property, CGT is charged at 18% within your unused basic-rate band and 24% above it, after the £3,000 annual exempt amount (for the tax year 2026/27). The gain must be reported and the tax paid within 60 days of completion through HMRC’s online service. Late filing attracts penalties and interest.
Important to Know: Selling a rental property triggers Capital Gains Tax of 18% or 24%, and it must be reported and paid within 60 days of completion.
Worked Example: A Landlord Decides to Exit the Market
David bought a Buy-to-Let property in 2014 for £180,000. After several years of rising compliance costs, Section 24 restrictions and the introduction of the Renters Rights Act, he decides to sell in 2026 for £350,000.
Item | Amount |
|---|---|
Sale Price | £350,000 |
Less Purchase Price | (£180,000) |
Less Buying and Selling Costs | (£10,000) |
Chargeable Gain | £160,000 |
Less Annual Exempt Amount | (£3,000) |
Taxable Gain | £157,000 |
CGT at 24% | £37,680 |
David receives £350,000 from the sale, but nearly £38,000 is payable in Capital Gains Tax. The tax must generally be reported and paid within 60 days of completion, making it one of the largest immediate costs of exiting the Buy-to-Let market.
Option 2. Incorporate & Keep Letting Through A Company
For portfolio landlords hit hardest by Section 24, moving into a limited company is the route that lets them stay invested while improving their tax position. Companies can still deduct mortgage interest in full and only have to pay Corporation Tax (19% to 25%) rather than Income Tax (up to 45%). This is the route generating the most enquiries, and the one with the most expensive traps.
Section 24 Is the Usual Driver
Since 2020, individual landlords can no longer deduct mortgage interest from rental profit. They receive only a basic rate 20% tax credit. Higher-rate landlords, therefore, pay tax on turnover rather than true profit. A company is not subject to Section 24, which is why leveraged portfolios increasingly sit inside one.
The Two Taxes Incorporation Triggers
Transferring property from your own name to your company is a disposal at market value, so two charges arise at once. Capital Gains Tax can be deferred under incorporation relief mandated by the Taxation of Chargeable Gains Act (TCGA) 1992 s.162 if the transfer qualifies, but Stamp Duty Land Tax is charged on the market value of the properties moved, including the higher-rate surcharge, unless partnership rules under Finance Act 2003 Sch 15 reduce it.
Two conditions decide whether incorporation works.
First, your letting must be a genuine business, not a passive investment. There is no statutory definition for “genuine business.” The test of genuineness comes from case laws like Ramsay v HMRC [2013] UKUT 226 (TCC), where roughly 20 hours a week of hands-on management was declared sufficient to pass as a genuine business. A single property run entirely by an agent will struggle to qualify.
Second, a procedural change that is now law. For transfers on or after 6 April 2026, incorporation relief no longer applies automatically. It must be actively claimed in the Self Assessment Tax Return for the year of transfer, and the election to disapply it (s.162A TCGA 1992) has been repealed. This was announced at the Autumn Budget 2025 and legislated in the Finance Act 2026. Miss the claim and a landlord could face an unexpected CGT bill even where every condition is met. There is no statutory clearance, so robust evidence and correct filing are essential.
Important to Know: From 6 April 2026, incorporation relief must be actively claimed on the Self Assessment Tax Return. It is no longer automatic, and the option to disapply it has been removed.
Worked Example: A Landlord Moves a Growing Portfolio Into A Company
Priya owns four Buy-to-Let properties that she acquired over the last decade. The portfolio is now worth around £1.2 million, with outstanding mortgages of £650,000. The properties generate healthy rental income, but she is increasingly frustrated by the ongoing impact of Section 24 and wants to build the portfolio for the long term.
After taking advice, she explores transferring the portfolio into a limited company.
Item | Without Incorporation Relief | With Incorporation Relief |
|---|---|---|
Current Portfolio Value | £1,200,000 | £1,200,000 |
Combined Capital Gain | £300,000 | £300,000 |
Capital Gains Tax at 24% | £72,000 | £0 (Gain Deferred) |
SDLT on Transfer | Potentially payable | May be reduced if specific reliefs apply |
In this scenario, incorporation relief could prevent an immediate £72,000 Capital Gains Tax bill, allowing the gain to be rolled into the value of the shares issued by the company. That can make incorporation far more affordable than an outright sale.
However, the transaction is not tax-free. SDLT may still arise on the transfer, particularly where mortgages are involved, and HMRC closely scrutinises arrangements designed to eliminate SDLT altogether. The incorporation must also qualify as the transfer of a genuine property business rather than a passive investment portfolio.
For Priya, the attraction is not simply the CGT deferral. Once the properties are held within a company, mortgage interest is generally deductible in full for corporation tax purposes, which may improve the portfolio's long-term profitability.
Option 3. Stay Put & Adapt
For many landlords, doing nothing remains the right answer. Incorporating a portfolio can trigger SDLT, professional fees and ongoing administrative costs, while a sale can crystallise a substantial CGT bill. If you own a property with little or no borrowing, or your rental profits fall within the basic rate band, remaining a sole owner may still be the most cost-effective route.
That does not mean standing still. Landlords who continue to own property personally need to adapt to a changing tax landscape. The most significant change is the introduction of the Making Tax Digital (MTD) for Income Tax.
Since 6 April 2026, landlords with qualifying income above £50,000 have been required to keep digital records and submit quarterly updates to HMRC under the new MTD regime. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028, bringing many more landlords into MTD.
There is still another consideration for landlords assessing future profitability. From 6 April 2027, rental profits will be subject to dedicated property income tax rates of 22%, 42% and 47%, which are two percentage points higher than the standard income tax bands. To partially offset this increase, the finance-cost tax credit available under Section 24 rises from 20% to 22%.
For landlords who stay in personal ownership, the question is therefore less about avoiding change and more about managing it. The property remains where it is, but the tax and reporting rules continue to evolve.
Important to Know: From 6 April 2027, rental profits will be taxed at 22%, 42% or 47%. These are two percentage points higher than the equivalent income tax bands.
How to Decide? Sell, Incorporate or Stay
The decision turns on three questions:
- How leveraged are you?
- What is your latent gain?
- Is your property letting a genuine business?
As a broad guide:
- Lean towards selling if the property is low-yield, faces a heavy EPC upgrade, or no longer fits your life, but model the CGT and the Ground 1A timing first
- Lean towards incorporating if you are a higher-rate taxpayer with a leveraged portfolio that qualifies as a business and you intend to reinvest profits
- Lean towards staying if you hold one or two unencumbered properties as a basic rate taxpayer, where the cost of incorporation outweighs the Section 24 saving
None of these is a calculator answer. The Ground 1A timing, the s.162 business test, and the SDLT partnership question are all fact-specific, and getting any of them wrong is expensive.

Conclusion
Whether you sell, incorporate or stay where you are is ultimately a tax and financial decision. The same property can produce three very different outcomes depending on how it is owned, how much borrowing is attached to it, and what your long-term plans are.
At UK Property Accountants, we help landlords model all three scenarios, identify the true cost of each option, and implement the strategy that leaves them in the strongest financial position.

FAQs
The maximum civil penalty is £40,000 for offences, such as misusing a possession ground. This took effect on 1 May 2026, and councils can choose to prosecute which can then lead to an unlimited fine.
Generally, yes. A rent repayment order can be made against the landlord even where the breach resulted from the agent’s conduct. Responsibility sits with you.
Capital Gains Tax applies at 18% (basic rate) or 24% (higher rate) on the gain above the £3,000 annual exempt amount, and must be reported and paid within 60 days of completion.
Yes, but only using Ground 1A under Section 8. It needs four months’ notice, cannot be used in the first 12 months of the tenancy, and you must be able to evidence a genuine intention to sell.
It can be, for higher rate taxpayers with leveraged portfolios that qualify as a business, because companies escape Section 24 and pay Corporation Tax. But incorporation triggers SDLT and only defers CGT if the s.162 conditions are met, so it is rarely worthwhile for one or two unmortgaged properties.
