Landlords who have received rental income without reporting the correct amount of tax should consider making an HMRC landlord tax disclosure as soon as possible.
HM Revenue and Customs operates the Let Property Campaign, which allows individual residential landlords to voluntarily disclose previously undeclared rental income. After notifying HMRC, the landlord will normally have 90 days from the date of HMRC’s acknowledgement to calculate the tax, interest and penalties due, submit the disclosure and make payment or agree a payment arrangement.
Coming forward voluntarily will not automatically remove penalties. However, HMRC states that penalties will usually be lower when a landlord discloses unpaid tax before HMRC discovers the issue itself.
Important: A disclosure must be complete and accurate. Landlords dealing with several properties, overseas income, missing records, jointly owned properties or deliberate non-compliance should consider obtaining advice from a qualified tax professional.
What Are HMRC Landlord Tax Disclosures?
An HMRC landlord tax disclosure is a formal declaration of rental income, gains or other tax liabilities that were not correctly reported in previous tax years.
For individual residential landlords, the main disclosure route is HMRC’s Let Property Campaign.
The campaign is designed to help landlords bring their tax affairs up to date by declaring:
- Previously unreported rental income
- Rental income omitted from a Self Assessment return
- Incorrectly calculated property profits
- Expenses that should not have been claimed
- Income from more properties than were reported
- Rental income from overseas residential property
- Other unpaid Income Tax or Capital Gains Tax liabilities
The Let Property Campaign does not provide a tax amnesty. A landlord will normally still need to pay the unpaid tax, statutory interest and any applicable penalties.
Who Can Use The Let Property Campaign?
The campaign is mainly available to individual landlords who receive income from residential property in the UK or overseas.
It may cover someone who:
- Lets one residential property
- Owns a portfolio of rental properties
- Rents out a furnished or unfurnished home
- Lets a holiday property
- Rents out a room in their main residence above the applicable exemption
- Became a landlord after inheriting a property
- Moved abroad while retaining a UK rental property
- Lives in the UK and receives income from foreign residential property
HMRC provides an online Let Property questionnaire that can help an individual check whether the campaign is appropriate.
Who Cannot Normally Use It?
The Let Property Campaign is not normally the correct route for:
- Limited companies
- Trusts
- Landlords disclosing only commercial property income
- Lettings involving only a shop, garage, lock-up or other non-residential premises
- Taxpayers already under an HMRC compliance check relating to the same income
- People whose tax position must be corrected through an outstanding or amendable tax return
A company, trust or commercial landlord may still need to disclose unpaid tax, but a different HMRC disclosure process may apply. HMRC’s broader voluntary disclosure guidance explains the alternatives.
HMRC Landlord Disclosure Next-Step Checker
Answer five questions to identify the HMRC route that may need checking first. The result distinguishes the Let Property Campaign from return amendments, outstanding returns and other disclosure procedures.
Important: This checker provides general routing information only. Eligibility depends on the full facts, including existing HMRC enquiries, the years affected and whether a return should instead be filed or amended.
When Must A Landlord Declare Rental Income?
A landlord is generally taxed on rental profit rather than the full amount of rent received. Rental profit is normally calculated by deducting allowable expenses from property income.
However, whether the landlord needs to contact HMRC or complete Self Assessment can depend on gross income, taxable profit, available allowances and the landlord’s wider tax circumstances.
The £1,000 Property Allowance
Individuals may qualify for a £1,000 annual property allowance against income from land or property.
Where the allowance is available:
- Gross property income of £1,000 or less will usually be covered automatically.
- A landlord with gross income above £1,000 may be able to claim the allowance instead of deducting actual expenses.
- Joint owners may each qualify for a £1,000 allowance against their own share of gross property income.
The allowance has exclusions and may not always produce the lowest tax bill. It cannot simply be assumed to apply to every property arrangement. HMRC’s property and trading allowance rules should be checked before calculating a disclosure.
The property allowance did not apply before the 2017/18 tax year, so it must not be deducted from earlier years included in a disclosure.
General HMRC Reporting Thresholds
HMRC’s public guidance states that an individual should generally:
- Contact HMRC where annual property income is more than £1,000 but no more than £2,500.
- Report it through Self Assessment where property profit after allowable expenses is more than £2,500; or
- Report it through Self Assessment where gross property income before expenses is more than £10,000.
These figures should not be treated as permission to ignore taxable income below the thresholds. A landlord already completing Self Assessment, someone who cannot use the property allowance or a person with other taxable income may still need to include the rental figures.
HMRC also provides a rental income checker covering income from a main home, another property, a room, land or a driveway.
Rent A Room Scheme
The Rent a Room Scheme can provide up to £7,500 of tax-free gross receipts where furnished accommodation is let in the individual’s only or main home.
The limit is reduced to £3,750 per person where the income is shared with someone else. Different calculation methods may be available where receipts exceed the threshold.
Someone using short-term accommodation platforms may also need to consider the tax treatment of Airbnb spare-room income in the UK, particularly where receipts exceed the Rent a Room limit or the property is not the host’s main home.
How Does A Landlord Make A Disclosure To HMRC?
The Let Property Campaign normally involves two formal stages.
1. Notify HMRC Of The Intention to Disclose
The landlord first tells HMRC that they intend to make a disclosure.
At this point, detailed calculations are not normally required.
HMRC will issue:
- A unique disclosure reference number
- A payment reference number
- An acknowledgement confirming the disclosure deadline
Joint owners cannot normally submit one combined disclosure. Each person must notify HMRC separately and disclose their own share of the income and tax liability.
2. Calculate The Amount Owed
The landlord must reconstruct the position for each relevant tax year, including:
- Total rent and other property receipts
- Deposits retained and treated as income
- Service charges or utility payments received
- The landlord’s ownership share
- Allowable day-to-day expenses
- Taxable property profit
- Applicable Income Tax rates for that year
- Interest on late-paid tax
- Any penalties due
- Other undisclosed income or gains that must be included
Tax rates, allowances and property rules can change between tax years. A disclosure covering several years must therefore use the correct rules for each year rather than applying the current tax rules retrospectively.
3. Submit The Formal Disclosure
The completed disclosure must explain:
- What went wrong
- Which years are affected
- How the income and expenses were calculated
- Whether the behaviour was reasonable, careless or deliberate
- How the proposed penalty was calculated
- Whether estimates were required
- Whether other unpaid tax liabilities exist
The landlord must declare that the information is correct and complete.
4. Pay HMRC Or Agree An Arrangement
HMRC must normally receive the completed disclosure and payment within 90 days of the notification acknowledgement.
Where full payment is not possible, the landlord should contact HMRC before submitting the disclosure. HMRC may ask for details of income, expenditure, savings, property, investments, mortgages, loans and other debts before considering a payment arrangement.
HMRC Disclosure Deadline Calculator
Enter the date shown on HMRC’s notification acknowledgement to calculate an indicative date 90 calendar days later and create a preparation schedule.
Important: This is an organisational calculator, not an HMRC deadline notice. HMRC normally allows 90 days from the acknowledgement, but the exact date stated by HMRC must be followed. Contact HMRC promptly if the date has passed or more time is needed.
Which Expenses Can Be Included?
Allowable expenses generally include revenue costs incurred wholly and exclusively for the day-to-day operation of the property business.
Examples may include:
- Letting agent fees
- Accountancy fees
- Buildings and contents insurance
- Routine maintenance and repairs
- Ground rent and service charges
- Council Tax paid by the landlord
- Cleaning and gardening
- Utility bills paid by the landlord
- Advertising costs
- Legal fees for qualifying short leases or lease renewals
- Replacement of qualifying domestic items
Capital expenditure is treated differently. The cost of purchasing a property, extending it or substantially improving it cannot normally be deducted from rental income as a routine expense.
For example, replacing a damaged kitchen unit with a modern equivalent may be a repair, while creating a new extension or materially upgrading the property may be capital expenditure.
HMRC’s rental property tax guidance provides examples of allowable residential property expenses.
A landlord should not copy deductions from general self-employment records without checking the property rules. Although the principles overlap, property income and trading income are separate tax categories.
Rental Income Reconstruction Worksheet
Enter one tax year at a time to produce an indicative rental-profit working. The worksheet separates gross receipts, ownership share, revenue expenses and residential finance costs.
Important: This worksheet is for record reconstruction only. Final tax depends on the tax year, accounting basis, ownership, other income, losses, reliefs and the legal treatment of each expense. Keep the underlying evidence and obtain professional review where records are incomplete or the property is overseas.
How Many Years Must Landlord Disclose?
The number of years depends largely on why the correct tax was not paid.
| Landlord’s circumstances | Potential disclosure period |
| Reasonable care was taken, but an error still occurred | Up to 4 years |
| The landlord was careless | Up to 6 years |
| The landlord deliberately understated the position | Up to 20 years |
| The landlord failed to notify HMRC of the income | Potentially up to 20 years |
HMRC states that it expects many landlords using the campaign to disclose no more than six years. Longer periods may apply where the landlord failed to notify HMRC or deliberately concealed or understated rental income.
The appropriate period should not be selected merely because it produces the lowest bill. The landlord must make an honest assessment of the behaviour that caused the error.
Potential HMRC Disclosure Period Checker
Select the description that most closely matches why the correct rental income was not reported. The result shows a potential look-back period, not a final legal classification.
Important: HMRC decides the legal behaviour and assessment period from the evidence. Four, six and up to 20 years are broad indicators; failure-to-notify rules, filing history and exact dates can change the result.
Are the Current and Previous Tax Years Included?
Not every recent year should automatically be placed in a Let Property Campaign disclosure.
HMRC’s current guidance distinguishes between:
- The current tax year
- The tax year immediately before the current year
- Older tax years
- Outstanding Self Assessment returns
- Returns that are still within the amendment period
In July 2026, the current tax year is 2026/27, running from 6 April 2026 to 5 April 2027.
Income received during 2026/27 should normally be recorded and reported through the appropriate current-year process rather than included as historic disclosure income.
Rental income for 2025/26 will normally be reported on the 2025/26 Self Assessment return, due online by 31 January 2027. Where a return has already been submitted and remains within the amendment window, it may need to be amended instead.
HMRC also states that outstanding returns issued for 2022/23 onwards must generally be completed rather than replacing those returns with campaign disclosure figures.
What Happens If Records Are Missing?
Missing records do not remove the obligation to disclose.
A landlord should first attempt to obtain evidence from:
- Bank statements
- Letting agents
- Tenancy agreements
- Mortgage statements
- Insurance providers
- Contractors and tradespeople
- Utility suppliers
- Online letting platforms
- Previous accountants
- Emails and property management systems
Where complete records cannot be recovered, HMRC allows reasonable estimates to be used.
The landlord should retain a clear explanation of:
- Why the original documents are unavailable
- Which figures were estimated
- What evidence was used
- How the calculation method was chosen
- Why the resulting estimate is reasonable
HMRC may ask the landlord to justify those estimates. Weak, unexplained or selectively low estimates could cause the disclosure to be rejected.
HMRC can also charge record-keeping penalties of up to £3,000 where a person fails to maintain appropriate business records.
What Penalties Can HMRC Charge?
A landlord making a disclosure may have to pay:
- The unpaid tax
- Late-payment interest
- A behaviour-based penalty
HMRC charges interest from the original payment deadline until the tax is paid. Interest is calculated daily and must be included correctly for the disclosure to be complete.
The maximum penalty stated in the Let Property Campaign guidance is:
- Up to 100% of the unpaid tax for UK income or gains
- Up to 200% for an offshore liability
The actual percentage depends on matters including the following:
- Whether the disclosure was prompted or unprompted
- Whether the error was careless or deliberate
- Whether information was concealed
- How quickly the landlord acted
- The quality and completeness of the disclosure
- The landlord’s cooperation with HMRC
A landlord who took reasonable care may not be charged a penalty, although tax and interest may still be payable. Voluntary disclosure normally provides a better opportunity for penalty reduction than waiting for HMRC to identify the income.
Landlord Disclosure Penalty Risk Explainer
Review the factors HMRC may consider when assessing penalties. The result is a qualitative preparation warning and deliberately does not estimate a penalty percentage or amount.
Important: This is not an HMRC penalty calculator. HMRC may charge tax, daily interest and a behaviour-based penalty. The Let Property Campaign guidance states maximum penalties can reach 100% of UK tax and 200% for an offshore liability, but the actual outcome depends on the facts and quality of disclosure.
Can HMRC Discover Undeclared Rental Income?
Landlords should not assume that cash payments, overseas property or income received through an online platform will remain outside HMRC’s view.
Certain digital platform operators are required to collect seller information and report relevant income details to HMRC. These rules can cover platforms that facilitate property rental and other services.
HMRC may also compare information from tax returns with third-party or government-held records. A discrepancy can lead to a compliance check, information request or formal investigation.
A disclosure made after HMRC has contacted the landlord may be treated as prompted, potentially reducing the scope for penalty mitigation.
How Is Jointly Owned Rental Property Disclosed?
Each owner is normally responsible for declaring their own share of the property income.
Joint ownership does not automatically create a tax partnership. In many cases, each owner’s share forms part of their individual property business.
Married couples and civil partners who live together are normally taxed on income from jointly owned property on a 50:50 basis, unless a valid declaration supported by evidence of unequal beneficial ownership applies.
Unmarried joint owners are generally taxed according to their actual entitlement to the income.
For a Let Property Campaign disclosure:
- Each owner should notify HMRC separately.
- Each person should use their own disclosure reference.
- Each disclosure should contain that person’s share of income, expenses, tax, interest and penalties.
- The combined amounts should reconcile with the property’s full records.
One owner cannot normally correct the entire position through a single personal disclosure.
What If the Property Is Overseas?
A UK tax resident may need to report rental income from property situated abroad.
The disclosure may need to consider:
- Foreign rental income
- Overseas property expenses
- Exchange rates
- Foreign tax paid
- Foreign tax credit relief
- Residence status
- Remittance rules for relevant historic periods
- Offshore penalty rules
Offshore disclosure penalties can be substantially higher than those applying to UK income. HMRC states that penalties may reach 200% of the unpaid offshore tax in some circumstances.
Complex overseas cases should generally be reviewed by an adviser experienced in international personal tax.
Does Making Tax Digital Affect Landlords?
Making Tax Digital for Income Tax began applying to the first mandatory group of landlords and sole traders on 6 April 2026.
A person generally falls within the system where they are registered for Self Assessment and their combined gross income from property and self-employment exceeds the applicable threshold.
The rollout is based on qualifying income from an earlier tax year:
| Qualifying gross income | Mandatory MTD start |
| More than £50,000 in 2024/25 | 6 April 2026 |
| More than £30,000 in 2025/26 | 6 April 2027 |
| More than £20,000 in 2026/27 | 6 April 2028 |
Qualifying income is generally measured before expenses. Where a property is jointly owned, only the person’s share of the gross property income counts towards their threshold.
Affected landlords must use compatible software to maintain digital records, send quarterly updates and complete the required year-end submission.
The current Making Tax Digital rules for landlords and self-employed people explain the thresholds, record-keeping requirements and submission deadlines in more detail.
Making Tax Digital does not correct undeclared income from earlier tax years. Historic errors must still be disclosed or corrected through the appropriate HMRC route.
What Are the Most Common Landlord Disclosure Mistakes?
Several mistakes can lead to an incomplete disclosure or an incorrect settlement.
Reporting Net Rent Instead of Gross Receipts
The landlord should begin with the full income received before deducting management fees, repairs or other expenses.
Claiming Capital Improvements as Repairs
- An extension, structural alteration or substantial upgrade may be capital expenditure rather than a deductible repair.
Using the Current Tax Rate for Every Year
- Each year must be calculated using the relevant historic Income Tax rates, allowances and property rules.
Deducting the Property Allowance Before 2017/18
- The £1,000 property allowance cannot be applied to earlier tax years.
Combining Joint Owners in One Disclosure
- Each landlord normally needs a separate notification, disclosure reference and calculation.
Omitting Other Undeclared Income
- Participation in the Let Property Campaign may require the individual to include other unpaid liabilities, such as unreported business income, investment income or capital gains.
- A landlord who also has freelance or platform earnings should check the wider process for declaring additional income to HMRC.
Submitting Before Discussing Payment Problems
- Someone who cannot pay the full amount should contact HMRC before submitting the disclosure, rather than sending an incomplete payment without explanation.
Assuming an Agent Has Already Reported Everything
- A letting agent collecting rent does not automatically satisfy the landlord’s personal tax obligations.
What Should a Landlord Do Before Contacting HMRC?
A practical preparation process is to:
- List every property let during the affected years.
- Identify the legal and beneficial owners.
- Gather rent statements, bank records and tenancy documents.
- Separate gross receipts from refundable deposits.
- Categorise expenses as revenue, capital or non-deductible.
- Identify outstanding or amendable tax returns.
- Check eligibility for the property allowance or Rent a Room Scheme.
- Establish whether the behaviour was reasonable, careless or deliberate.
- Calculate tax using the rules for each relevant year.
- Calculate statutory interest and potential penalties.
- Identify any other undisclosed income or gains.
- Consider professional advice before making the formal declaration.
Notification should not be unnecessarily delayed. However, the final disclosure should not be submitted until the landlord is satisfied that it is complete and supportable.
Final Answer
HMRC landlord tax disclosures allow individual residential landlords to correct unpaid tax on previously undeclared rental income.
The landlord should first notify HMRC through the Let Property Campaign. After receiving the acknowledgement and reference numbers, they normally have 90 days to calculate the unpaid tax, interest and penalties, submit a complete disclosure and pay the amount due or agree a payment arrangement.
Depending on the circumstances, the disclosure may cover up to four, six or 20 years. The correct period depends on whether the landlord took reasonable care, acted carelessly, failed to notify HMRC or deliberately understated the income.
Coming forward voluntarily does not remove the underlying tax liability, but it will normally place the landlord in a better position than waiting for HMRC to identify the undeclared income.
Frequently Asked Questions
Is the Let Property Campaign still open in 2026?
Yes. HMRC’s Let Property Campaign remains available to eligible individual residential landlords with previously undisclosed tax liabilities. HMRC updated its detailed campaign guidance on 6 April 2026.
Will HMRC waive the tax if a landlord comes forward voluntarily?
No. The landlord will normally need to pay the unpaid tax and late-payment interest. A penalty may also be charged, although voluntary disclosure can result in a lower penalty than waiting for HMRC to discover the income.
How long does a landlord have after notifying HMRC?
The formal disclosure and payment must normally be made within 90 days of the date on HMRC’s notification acknowledgement.
Can an accountant make the disclosure?
Yes. An authorised tax adviser can notify HMRC and prepare the disclosure on the landlord’s behalf. The landlord remains responsible for ensuring the information is accurate and complete.
Can one disclosure cover a husband and wife?
No. Where both individuals have undisclosed rental income, HMRC normally requires separate notifications and disclosures showing each person’s share.
Does a rental loss need to be disclosed?
A year in which allowable expenses exceed rental income may not create tax payable and may not need to be included as a liability year. However, calculating and carrying forward property losses can be complex, particularly where earlier returns were incorrect.
Can the £1,000 property allowance be used for every year?
No. It applies only from the 2017/18 tax year and is subject to eligibility rules. It cannot be used for earlier years.
What happens if HMRC rejects the disclosure?
HMRC may reject a disclosure that is incomplete, inaccurate or based on an inappropriate penalty calculation. The landlord could then face a compliance check, revised tax calculations and potentially higher penalties.
