Claiming lettings relief

If you have tenants in your home, it’s essential to understand the Capital Gains Tax (CGT) implications. Typically, there is no CGT on the sale of a property used as your main residence due to Private Residence Relief (PRR). However, if part of your home has been let out, your entitlement to PRR may be affected.

Homeowners who let out part of their property may not qualify for the full PRR, but they could be eligible for letting relief. Letting relief is available to homeowners who live in their property while renting out a portion of it.

The maximum letting relief you can claim is the lesser of the following:

  • £40,000
  • The amount of PRR due
  • The chargeable gain made on the part of the property let out

Example:

  • You rent out a large bedroom to a tenant, making up 10% of your home.
  • You sell the property and make a gain of £75,000.
  • You qualify for PRR on 90% of the property (£67,500).
  • The remaining gain of £7,500 relates to the portion of the home that’s been let.

In this case, the maximum letting relief due is £7,500, which is the lower of:

  • £40,000
  • £67,500 (the PRR due)
  • £7,500 (the gain on the part of the property that’s been let)

As a result, you would not owe any CGT—the £75,000 gain is fully covered by £67,500 in PRR and £7,500 in letting relief.

Note that if you have a lodger who shares living space with you or if your children or parents live with you and pay rent or contribute to housekeeping, you are not considered to be letting out part of your home for tax purposes.

Report and pay Capital Gains Tax

If you have sold a UK residential property since 6 April 2020, it is important to be aware that the reporting and payment deadlines for Capital Gains Tax have changed. For property sales completed on or after 27 October 2021, any Capital Gains Tax that becomes payable must now be reported and paid within 60 days of completion. This applies where the property is not fully covered by the private residence exemption. For example, where the property was a rental property, a second home, or only partly used as your main residence. If the property was jointly owned, each owner must report their own share of the gain.

To calculate the gain, you will need information about the dates of purchase and sale, the original purchase price, legal fees and other costs, plus any significant improvement expenses. Estate agency and legal costs on sale will also be needed. The sooner you gather these details, the easier it is to meet the deadline.

For other types of capital gains, for example shares, investments, or commercial property sold by a UK resident, the reporting is usually carried out through your Self Assessment return for the tax year concerned. In some cases it is possible to report gains in real time, rather than waiting until the tax return is due, but this depends on the circumstances. 

If you use the “real time” Capital Gains Tax service, this is available for UK residents disposing of certain assets (not including UK residential property) in the current tax year. If this route is used, the reporting deadline is by 31 December after the end of the tax year of disposal, with payment due by 31 January.

If you think you may have sold or are planning to sell a property or other asset that could give rise to a taxable gain, please contact us as soon as possible. Early information means that we can ensure the calculations are correct and the reporting deadlines are met, which helps avoid unnecessary interest or penalties.

Don’t be tempted to withhold pay as a form of leverage

Ms Constantine had been a veterinary surgeon since 2017. Initially, she had worked every day with two half days rest, but this increased to four full days and a weekend every three weeks. Moreover, she was required to seek permission to be absent on those days she was not required to attend work. In November 2020, Ms Constantine began a sickness absence, claiming burnout, and was certified as being unfit to work from 1 December 2020 to 4 January 2021 due to anxiety. In May 2021, a ‘fit for work’ statement recommended one day a week, which was subsequently increased in June 2021 to one and a half days a week, with at least one day off between workdays. 

Following a meeting on 22 June 2022, the respondent agreed to look into issuing a new contract for a three-and-a-half-day week with two in six weekends. A proposed contract with a covering letter dated 24 August 2022 was sent to the claimant with a £23,267 gross salary per annum, which was not in alignment with the agreed basis that it should be based, pro rata, on her previous full-time salary of £44,000 p.a. The claimant contended that the revised salary calculations were severely flawed and effectively constituted a 22.4% pay cut based on a new notional denominator of 260 working days in the form of a ‘take it or leave it’ offer. 

Further, a series of unauthorised wage deductions had been made from May 2021 to 31 July 2023, and Ms Constantine ultimately resigned in 2023, lodging a formal grievance on 14 March 2023, specifically complaining about the basis of the calculations of her pro-rata pay from May 2021, asserting a breach of the Part-Time Worker (PTW) Regulations 2000 and unlawful deduction from wages.

The Tribunal ruled in favour of Ms Constantine, finding an unlawful deduction from wages, constructive unfair dismissal, and unfavourable treatment arising in consequence of disability, and she was awarded a total of £19,017.  Ms Constantine was deemed to have been a disabled person from December 2021 due to chronic fatigue, as the respondent should have known, and the act of proposing a new part-time contract in August 2022 at a disproportionately low salary constituted unfavourable treatment arising from the claimant’s need to reduce her hours due to disability (s.15 Equality Act 2010).

The claim for constructive unfair dismissal was upheld because the respondent had committed a fundamental breach of contract by withholding admitted back pay and making its payment conditional on the claimant agreeing to the proposed future salary. Finally, the Tribunal found that an unauthorised deduction from wages had occurred, applying the Apportionment Act 1870 to set the lawful deduction rate at 1/365th of the annual salary for days the claimant was rostered to work but was absent.

When seeking to reduce an employee's hours, any resulting contract must be calculated correctly on a pro-rata basis in accordance with the PTWs. Employers must prove that any proposed pay revisions are not only fair, but also "necessary and appropriate" to achieve a legitimate business aim. Above all, employers must never deliberately withhold payment in an effort to coerce an employee into agreeing to new contractual terms. Such an act risks breaching the implied term of mutual trust and confidence, creating grounds for constructive unfair dismissal.

Why solvency is the true test of business strength

Every successful business, no matter how innovative or fast-growing, ultimately depends on one simple measure: solvency. A solvent business is one that owns more than it owes, with sufficient assets to cover its debts and the means to continue trading. It is not just an accounting concept, but a signal of underlying financial health and resilience.

Solvency shows that a business can meet its obligations, even during difficult trading periods. When liabilities are kept under control and supported by tangible or liquid assets, a company is less vulnerable to cash flow shocks, rising interest rates or late payments from customers. It provides confidence to suppliers, lenders and investors that the firm is being managed prudently and that short-term fluctuations will not lead to crisis.

Maintaining solvency also provides flexibility. A business that operates with positive net assets can reinvest in growth, negotiate better borrowing terms and respond quickly to new opportunities. In contrast, firms that operate on the edge of insolvency often spend much of their time managing creditors, juggling payments or seeking emergency funding, which can distract from long-term strategy.

There are wider benefits too. Solvent companies tend to attract better staff and more loyal customers, as both groups are reassured by signs of stability. Regulators, insurers and trade bodies all view solvency as a key indicator of sound governance and reliability. For owner-managed firms, it can also make a significant difference when planning for succession, exit or sale, as buyers and investors typically value strong balance sheets and minimal debt exposure.

Regular financial reviews, realistic cash flow forecasts and disciplined control of borrowing are all essential to sustaining solvency. While profit is the measure most often discussed, solvency is the foundation that supports it. A business may trade at a loss for a short period and recover, but once it becomes insolvent, the options narrow rapidly. In uncertain economic conditions, staying solvent remains the clearest mark of real business strength.

UK productivity remains disappointingly weak

The UK continues to struggle with low productivity growth, a long-running challenge that shows little sign of improvement. In the three months to June 2025, output per hour worked was around 1.5% above its pre-pandemic level, but it actually fell by almost 1% compared with the same period a year earlier. The previous quarter had seen only a marginal rise and overall, the trend is one of stagnation rather than sustained growth.

Although the figures appear slightly better than before the pandemic, they underline a deeper problem. Productivity growth has been flat for much of the past fifteen years, averaging only around 0.5% per year since the financial crisis, compared with about 2% annually in the decades before 2008. This persistent weakness limits the economy’s ability to generate higher living standards, boost wages and support stronger public finances.

What lies behind the figures

Several factors contribute to the poor results. A shift in activity towards lower-productivity industries has diluted national performance, as sectors such as retail, hospitality and parts of the public sector expanded while more productive sectors grew more slowly. The public sector itself has seen a notable rise in hours worked, particularly in health and social care, without a matching increase in measured output.

Regional disparities also continue to weigh on national averages. London and the South East maintain far higher productivity levels than many other parts of the country, particularly regions with weaker transport links and lower investment. Capital investment remains subdued overall, and many businesses have been slow to adopt new technology or digital systems that could raise efficiency.

The bigger picture

For all the political focus on growth, the UK remains trapped in what economists often call a productivity puzzle. The country is producing more than before the pandemic, but only slightly and progress is fragile. Without stronger investment, skills development and incentives to innovate, productivity gains are likely to remain modest, constraining both wage growth and the government’s ability to fund improvements in public services.
