Selling a property at a loss may seem like a financial setback, but it doesn’t have to be all bad news. While most property investors and homeowners focus on Capital Gains Tax (CGT) when selling a property at a profit, many overlook the opportunity to make capital losses work for them. If you sell a property for less than you originally paid, you could use that loss to reduce future tax liabilities.
In this guide, we’ll explain how to report a property sale at a loss, how to use capital losses to offset future CGT bills, and how these losses can be carried forward to reduce taxes in later years. Whether you are a seasoned investor or a first-time seller, understanding how to report losses and utilise them effectively can have a significant impact on your long-term tax planning strategy.
What Is Capital Gains Tax on Property?
Capital Gains Tax (CGT) is the tax levied on the profit made from the sale of certain assets, including property. However, it doesn’t apply to all property sales. If you sell a property for more than you paid for it, the gain is taxable. But if you sell a property for less than you purchased it for, you’re making a capital loss instead of a gain.
For example, if you bought a buy-to-let property for £300,000 and sold it for £250,000, you'd have a £50,000 capital loss, assuming there are no other adjustments. This capital loss can help reduce your overall tax bill in the future.
When Is CGT Applicable?
Capital Gains Tax (CGT) applies when you sell a property that isn't your main home, such as a second home or rental property. If you sell at a loss, you don't pay CGT, but the loss can offset future gains. CGT may also apply to your main home if it wasn't fully occupied as your primary residence, such as when part of the property was rented out. However, reliefs like Private Residence Relief may reduce or eliminate CGT in certain cases.
How Does a Capital Loss Arise?
Capital losses on property sales can arise in several situations, such as market downturns, forced sales, or when a property requires significant repairs or improvements. While these factors may lower the sale price, they don't always guarantee a loss whether a loss occurs depends on the difference between the sale price and the original cost.
Understanding Allowable Costs
The costs associated with the property that can be deducted include:
- Legal fees
- Estate agent fees
- Stamp duty and other transaction fees
- Improvements to the property (e.g., renovations that increase its value)
For example, if you bought a property for £200,000, sold it for £180,000, and spent £5,000 on legal fees, your capital loss would be £25,000 (the sale price minus the purchase price and deductible costs). However, repairs and maintenance costs are not deductible for CGT purposes.
How Capital Losses Work for UK CGT Purposes?
Capital losses can be used to reduce the amount of Capital Gains Tax (CGT) you need to pay by offsetting them against gains you make when you sell assets like property or shares.
1) Set Losses Against Gains in the Same Tax Year
When you sell an asset at a loss, that loss can be used to offset any capital gains made in the same tax year, effectively reducing your taxable gain. This means that you must apply any losses before considering your annual exempt amount. By doing so, you can reduce the overall amount of tax you owe on your gains, as the loss directly reduces the taxable income from other assets you've sold.
For example,
If you have a £50,000 gain and a £40,000 loss, the loss reduces your taxable gain to £10,000. You can then apply your annual exempt amount (e.g. £12,000), covering the entire £10,000 and leaving no taxable gain.
However, if your loss is £60,000, it fully offsets the £50,000 gain, leaving no taxable gain. In this case, the annual exempt amount is unused and effectively lost.
2) Carry Forward Losses to Future Years
- If your capital losses are greater than your gains in the same tax year, you can carry forward the remaining loss to future tax years.
- These carried‑forward losses can reduce taxable gains in later years.
To do this, you must report the loss to HMRC (through your Self-Assessment return or in writing if you don’t normally file returns).
There is no time limit on how far forward you can carry losses once they are reported, but you must claim them within four years of the end of the tax year when the loss arose.
3) Main Home (Private Residence Relief) and Losses
- If you sell your main home and the sale qualifies for Private Residence Relief, the relief covers the gain so no tax.
- If you sell your main home at a loss, you can use the loss unless that loss is due to PRR.
Connected Persons
If the loss arises from disposing of an asset to a connected person (like a family member), then special rules apply and you may only be able to use the loss against gains from disposals to that same person.
No Offset Against Income
Capital losses typically can't be set against income (e.g., wages) and can only reduce capital gains. However, losses from qualifying shares in schemes like the Enterprise Investment Scheme (EIS) or Seed Enterprise Investment Scheme (SEIS) can sometimes be offset against income, under certain conditions.
Summary
Aspect | Details |
|---|---|
Capital loss | A capital loss occurs when you sell an asset for less than you paid for it (e.g., property, shares). |
Set Losses Against Gains | Losses can be set against gains in the same tax year to reduce taxable gains. (e.g., £30,000 gain offset by £20,000 loss = £10,000 taxable gain). |
Carry Forward Losses | Losses exceeding gains in the same year can be carried forward to offset future capital gains. Losses must be reported to HMRC within 4 years. |
Main Home (PRR) | Loss on the main home cannot be used to offset other taxable capital gains (if fully exempt under Private Residence Relief). |
Reporting Losses to HMRC | Losses must be reported to HMRC (via Self Assessment or in writing) within four years of the end of the tax year when the loss occurred. |
Connected Persons | Special rules apply if the loss is from a transaction with a connected person (e.g., family). Losses can only offset gains from the same person. |
No Offset Against Income | Capital losses cannot offset income (e.g., salary, interest) except in very limited cases (e.g., qualifying shares). |

How to Report a Property Sale at a Loss to HMRC
Step 1 - Work Out Whether You Must Report
For UK residential property sales completed on or after 27 October 2021, non‑UK residents must report the disposal to HMRC within 60 days, even if a loss is made. UK residents do not need to file a 60-day return for a loss but may do so to formally record it.
If you are a UK resident and file a Self-Assessment tax return, you can report the loss on the SA108 capital gains pages for the relevant tax year.
Step 2 - Gather All the Required Information
To report a loss or disposal, you'll need the property address and postcode, along with the dates of purchase and sale (completion date). You'll also need the purchase price and sale price, as well as any transaction costs such as legal fees, estate agent fees, and allowable improvement costs.
Additionally, include any reliefs or exemptions you're claiming and provide the calculation of gain or loss, even if the figure is negative.
Step 3 - Use the Correct HMRC Reporting Route
A) 60‑Day Report via the ‘Capital Gains Tax on UK Property’ Service
Use this online service if:
- You are non‑UK resident and disposing of UK residential property (loss or gain).
To use the service:
- Sign in or create a HMRC Government Gateway account.
- Go to the Capital Gains Tax on UK Property reporting service.
- Enter details of the disposal and the loss.
- Submit the return before the 60‑day deadline.
Note:
For UK residents with a loss and no tax to pay, reporting via the 60‑day service is optional, but it ensures HMRC formally records your capital loss so you can carry it forward later.
B) Report on Your Self-Assessment (SA108)
If you already:
- File a Self-Assessment tax return, and
- The property disposal occurred in the relevant tax year,
you should include the loss on the SA108 capital gains pages of your annual tax return. This ensures the loss appears in HMRC’s records as part of your overall gains/losses for the year.
Note:
Recording a loss on SA108 does not replace the 60‑day requirement if you are non‑UK resident or if HMRC requires a 60‑day submission for UK residents under specific circumstances.
Step 4 - Keep Records and Confirm Submission
After you submit:
- Keep a copy of your submission confirmation from HMRC.
- Save calculations and evidence (purchase/sale contracts, invoices, etc.) in case HMRC requests them later.
What Happens After Reporting a Loss?
Once you’ve reported the capital loss to HMRC, you can use that loss to offset any taxable gains in the same tax year or carry it forward to future years.
Offsetting Future Gains
One of the primary benefits of reporting a capital loss is that you can offset it against future capital gains. This can result in significant tax savings, especially if you anticipate making large profits on property sales in the coming years.
Carrying Losses Forward
If you don’t have any gains in the same tax year to offset your loss, you can carry the loss forward. For example, if you sell a property at a £15,000 loss in one year but make £30,000 in profit the next year, you can use that £15,000 loss to reduce the taxable profit in the following year.
Using Capital Losses to Benefit Your Future Tax Planning
Long-Term Tax Savings
When managed properly, capital losses can significantly reduce your future tax liabilities. For property investors who buy and sell regularly, having a strategy to utilise losses in the right way can result in long-term tax savings. By applying capital losses to future property sales, you lower the amount of CGT you need to pay.
Offsetting Losses to Lower Your Capital Gains Tax
Under HMRC rules, capital losses that are properly reported can be used to reduce your taxable capital gains, ensuring you pay tax only on your net gains. These losses are known as allowable losses and must be reported to HMRC (usually on your Self Assessment tax return) to be valid. Once reported, you first offset losses against gains in the same tax year. If any losses remain, HMRC allows you to carry them forward to offset gains in future years.
For example,
Example:
Year 1: Sell a property and make a £10,000 gain
Year 2: Sell another property and make a £5,000 loss
If you don’t report the Year 2 loss, HMRC will tax the full £10,000 gain. But if you report the £5,000 loss and claim it with HMRC, you can use it to reduce the taxable gain to £5,000 (£10,000 gain minus £5,000 allowable loss). That means you’re only taxed on the actual profit after losses, in accordance with HMRC guidance.
Practical Examples of Using Capital Losses
Let’s say you sold a rental property at a £30,000 profit and another property at a £20,000 loss in the same tax year. You can offset the loss against the gain, lowering the taxable gain to £10,000. This reduces your CGT liability for that year.
Common Mistakes to Avoid When Reporting Property Losses
Failing to Report the Loss
Not reporting a capital loss properly will prevent you from using it to offset future gains. Ensure you file the necessary paperwork on time.
Incorrectly Applying Losses
Don’t attempt to apply losses from property sales that are exempt from CGT, such as your main residence, as this will not be allowed.
Poor Record-Keeping
Keep detailed records of all property transactions, including receipts for improvements, legal fees, and agent commissions. Without proper documentation, it can be difficult to justify your reported losses to HMRC.
Conclusion:
Reporting and using capital losses is a valuable strategy for reducing your CGT liability. By understanding the process of reporting losses, carrying them forward, and applying them against future gains, property investors can optimise their tax position and avoid paying unnecessary taxes. Remember to report property sales at a loss to HMRC within the required timeframe and ensure you keep accurate records of all transactions.
Capital losses can be offset against gains in the same tax year or carried forward to future years, providing significant tax savings over time. By properly utilising capital losses and including them in your Self-Assessment tax return, you can enhance your financial flexibility. For tailored advice specific to your situation, consulting a tax professional is always a wise choice.
