HMRC Deliberate Tax Defaulters List Landlords: Could You Be at Risk?

Landlords

Posted in Jul 16 , 2026

The HMRC deliberate tax defaulters list is a public record published by HM Revenue & Customs. It includes individuals and businesses that have deliberately failed to meet their tax obligations and have received significant penalties after HMRC's compliance process has been completed.

For landlords, appearing on this list can damage both financial and professional reputation. Whilst not every tax mistake leads to publication, deliberate non-compliance carries serious consequences.

Understanding your responsibilities early helps you stay compliant, protect your investment, and avoid unnecessary problems.

Why Landlords Appear on the List?

Many landlords don't intentionally set out to break tax rules, but certain actions increase the risk of investigation and penalties. Common reasons include:

Undeclared rental income

Failing to report rental income is one of the most common reasons landlords face HMRC action. Whether the income comes from a single rental property or a larger portfolio, it should be declared correctly.

Inaccurate tax returns

Providing incorrect figures or leaving out important information may result in additional tax, penalties, and further investigation.

Poor record keeping

Missing invoices, incomplete rental records, or unclear expense claims make it harder to demonstrate compliance if HMRC reviews your tax affairs.

Ignoring HMRC correspondence

Responding promptly to HMRC requests often helps resolve issues more efficiently. Ignoring letters or requests for information can make matters worse.

Common Tax Mistakes Landlords Should Avoid

Good record keeping is one of the simplest ways to stay compliant.

Landlord Compliance Checklist

Declare all rental income accurately.
Keep records of rental payments and expenses.
Submit tax returns before the deadline.
Retain supporting documents for your records.
Review your tax position regularly.
Respond promptly to HMRC correspondence.

Following these steps helps improve landlord tax compliance and reduces the risk of unnecessary penalties.

What Happens During an HMRC Landlord Investigation?

An HMRC landlord investigation does not automatically mean a landlord has done something wrong. HMRC may ask for additional information to confirm that rental income and expenses have been reported correctly.

During an investigation, HMRC may:

Review tax returns.
Request financial records.
Check rental income and allowable expenses.
Calculate any unpaid tax.
Apply penalties where appropriate.

Cooperating fully and providing accurate records often helps the process run more smoothly.

How the Let Property Campaign Can Help

If you've previously received undeclared rental income, it's often better to come forward before HMRC contacts you.

The Let Property Campaign allows eligible landlords to voluntarily disclose unpaid tax on rental income. In many situations, making a voluntary disclosure can lead to lower penalties than waiting for HMRC to identify the issue.

If you're unsure whether the campaign applies to your circumstances, seeking professional tax advice from a property management London company is always recommended.

FAQs

Can landlords appear on the HMRC deliberate tax defaulters list?

Unfortunately, mistakes such as failing to declare rental income or submitting inaccurate tax information can lead to penalties, HMRC investigations, and, in serious cases, publication on the HMRC deliberate tax defaulters list landlords.

What counts as undeclared rental income?

Undeclared rental income is rental income that has not been reported correctly to HMRC. This may include income from residential properties, holiday lets, or other rental arrangements that should have been included in a tax return.

What are landlord tax penalties?

Landlord tax penalties depend on the circumstances of each case, including whether the error was accidental, careless, or deliberate. Penalties may increase where landlords knowingly fail to declare taxable rental income.

What happens during an HMRC landlord investigation?

During an HMRC landlord investigation, HMRC may review tax returns, request supporting documents, and assess whether rental income has been reported correctly. Not every investigation results in penalties, but accurate records are essential throughout the process.

What is the Let Property Campaign?

The Let Property Campaign is an HMRC initiative that allows eligible landlords to voluntarily disclose previously undeclared rental income before HMRC identifies the issue. Acting early may help reduce penalties compared with waiting for HMRC to open an enquiry.

Stay Compliant and Protect Your Rental Investment

Good property management and accurate record keeping go hand in hand. Understanding your tax responsibilities, keeping organised records, and addressing any issues early helps reduce the risk of investigations and penalties.

Stamp Duty Scrapped: Would It Really Make Buying Cheaper?

You've probably seen headlines about stamp duty being scrapped. If you're planning to buy a property, should you buy now and pay the tax, or wait in case the rules change?As of August 2026, Stamp Duty Scrapped is false news. The Government has said it does not intend to abolish SDLT, whilst reform proposals continue to attract attention.For buyers, the bigger question is whether waiting for a possible change would leave you better off.What Is the Current Stamp Duty Position in 2026?Scrapping Stamp Duty Land Tax would reduce the upfront cost of buying qualifying property. It would not automatically make the property itself cheaper. Current SDLT still applies in England and Northern Ireland, with different rates for first-time buyers, additional properties and other circumstances.For a buyer purchasing a single residential property, the current standard rates are:Property priceSDLT rateUp to £125,0000%£125,001 to £250,0002%£250,001 to £925,0005%£925,001 to £1.5 million10%Above £1.5 million12%There are also higher rates for additional residential properties and separate rules for non-UK residents, companies and certain other transactions.For a detailed explanation of current costs, see Cribs Estates' House Purchase Tax UK guide.How Much Could Stamp Duty Add to Your Purchase?The amount depends on the property price and your current situation. For example, a standard buyer purchasing a £400,000 home would pay:0% on the first £125,0002% on the next £125,000, which is £2,5005% on the remaining £150,000, which is £7,500The total SDLT would therefore be £10,000. A qualifying first-time buyer purchasing the same £400,000 property would pay £5,000 because the first £300,000 is covered by the relief and the remaining £100,000 is taxed at 5%.Could You Be Paying More Than You Expect?If buying another residential property means you own more than one property at the end of the purchase, higher SDLT rates will usually apply. Since 31 October 2024, these rates sit 5 percentage points above the standard residential rates.There are rules for replacing your main residence. If you buy your new home before selling your old one, you might initially pay the higher rates. If you then sell your previous main residence within the relevant 36-month period, you might qualify for a refund of the higher-rate element.So two people buying properties at the same price can face very different SDLT bills.Should You Buy Now or Wait for Stamp Duty Changes?Waiting for a possible tax saving sounds sensible. The problem is uncertainty. There is currently no confirmed abolition date, and Parliament's latest research states that the Government does not intend to abolish SDLT.If you've found the right property, delaying your purchase also means accepting uncertainty around the property itself, mortgage costs and future market conditions.On the other hand, if you're not in a hurry and the current SDLT bill makes the purchase difficult, waiting gives you more time to assess your options.Removing SDLT would lower the upfront cost for buyers who currently pay it. If more people then enter the market, demand could increase. If the supply of suitable homes does not increase at the same pace, stronger demand could put upward pressure on prices.What If You're Buying Whilst Keeping Another Property?You might be buying a new home whilst keeping your existing property as a rental. You might also be buying a second property for investment or adding another property to an existing portfolio.In these situations, the higher SDLT rates can affect the upfront cost. For example, HMRC's current higher-rate table puts the rate at 5% on the first £125,000 for an additional residential property, rising through the higher bands.Would Scrapping Stamp Duty Really Make Your Move Cheaper?At the point of purchase, removing SDLT would reduce one of your transaction costs. It would not automatically make the overall move cheaper. You would still need to consider:The purchase price.Mortgage costs.Solicitor and conveyancing fees.Surveys.Moving costs.Repairs or renovation.Insurance and ongoing property costs.What Should You Consider Before Buying?Before making a decision, review these five points:Your current SDLT liability.Whether you qualify for first-time buyer relief or another exemption.Whether the higher rates apply to you.Your total purchase and mortgage costs.Whether waiting creates more risk than the potential tax saving.If you're unsure about your individual tax position, speak to a qualified tax adviser.How Cribs Estates HelpsCribs Estates works with buyers, sellers, landlords and investors across the property market. Its services include property sales, lettings, valuations and property management.The team can help you assess the property itself, understand local market conditions and consider the wider factors affecting a purchase.For landlords and investors, Cribs Estates also provides ongoing property management support after purchase.You can explore Cribs Estates property management services for more detail.FAQsHas stamp duty scrapped law active in 2026?No. Stamp Duty scrapped law remains in place in England and Northern Ireland. Parliament's May 2026 research states that the Government does not intend to abolish SDLT.How much stamp duty will I pay when buying a house?It depends on the purchase price and your circumstances. First-time buyers, additional-property buyers and non-UK residents have different rules. HMRC provides the current rates and an SDLT calculator.Will I pay higher stamp duty if I already own a property?You will usually pay the higher rates if your purchase leaves you owning more than one residential property. Exceptions and refund rules apply in some circumstances.Should I wait to buy a house in case stamp duty changes?There is no confirmed abolition date. Compare the potential tax saving with the risks and costs of waiting, including mortgage costs, property availability and changes in property prices.Would scrapping stamp duty make house prices rise?It might increase buyer demand, which could put upward pressure on prices if housing supply remains limited. The effect would depend on how any future reform works.Would investors still pay stamp duty if it were scrapped?There is no confirmed abolition policy to answer this. Current SDLT rules treat additional residential properties, companies and some other transactions differently, so any future reform would need to specify which purchases qualify.

Government Landlord Tax Hikes: How Much More Will You Pay?

Anyone who owns a rental property has recently been left wondering what the new landlord tax hike means for their actual income. From 6 April 2027, separate Income Tax rates for property income will be 22% at the basic rate, 42% at the higher rate and 47% at the additional rate. Changes to Tax rates for Property, Savings and Dividend Income apply in England, Wales and Northern Ireland.

C1 or C3 Planning Use? Avoid Costly Buying Mistakes

You've found a property that meets your expectations. The location is right, the price is suitable, and you already have plans on how to use it. Then you hear someone saying, "Have you checked the planning use?"A lot of buyers only discover the importance of planning use after they've agreed on a purchase, delaying projects or requiring unexpected planning applications. Whether you are buying a home, investing in a property, or utilising a development opportunity, here’s why it’s important to know the planning categories of use before exchanging contracts.Why Planning Categories Matter Before You BuyPlanning categories of use tell how a property can legally be occupied or operated. It needs to be as per the use of planning conditions set by the government. C3 planning use generally applies to houses and flats used as permanent homes, whilst C1 planning use applies to hotels, guest houses, and similar short-term accommodation.The planning categories may affect:Whether your intended use is already permitted.Future renovation or conversion plans.Rental or investment opportunities.The property's resale potential.The time and cost are involved in changing its use.C1 Planning Use or C3 Planning UseBoth categories relate to buildings people occupy, they're designed for different purposes.C1 Planning UseC3 Planning UseHotels and guest housesHouses and flatsTemporary accommodationPermanent residential livingVisitors and short staysIndividuals and familiesCommercial accommodationResidential occupationWhat Is C3 Planning Use?C3 planning use is the most common planning category for residential properties. It covers homes occupied by individuals, families, or small groups living together as a single household. Most houses and flats you'll see on the market fall within this category. What Is C1 Planning Use?C1 planning use applies to buildings used for temporary accommodation, including hotels, boarding houses, and guest houses, where people stay for short periods rather than living there permanently.Read the planning use classes guidance to get more details about the use class orders.The Buying Mistakes That Cost Buyers MoneyOne of the biggest reasons property purchases become more expensive than expected is that buyers assume the planning use matches their intentions.Here are some of the most common mistakes.Assuming every residential-looking property has C3 planning useBuying before checking the planning historyAssuming short-term accommodation is automatically allowedIgnoring local planning policiesForgetting your long-term plansHow to Check a Property's Planning Use?It’s easier to check a property planning use before you buy than to deal with planning issues after you've completed the purchase. Here’s a checklist you should follow:Check the property's planning history on your local council's planning portal.Review previous planning permissions and approved changes of use.Ask the seller or estate agent to confirm the current planning use.Discuss any concerns with your solicitor during the conveyancing process.Contact the local planning authority if you're unsure whether your intended use is permitted.Taking these steps early can help you identify potential restrictions before they become costly problems.Planning Categories of Use and Your Future PlansUnderstanding planning categories of use isn't only important when buying a property. It also affects what you may be able to do with it in the future.For example, you might plan to:Extend the property.Convert it into an HMO.Create serviced accommodation.Redevelop or change its purpose.Sell it as an investment property.Each of these plans may involve different planning requirements depending on the property's existing use class and your local authority's policies.That's why it's important to think beyond today's purchase. Choosing a property with the right planning use can provide greater flexibility if your plans change later.FAQsCan I change a property's planning use?In some cases, yes. However, changing a property's planning use may require planning permission from your local planning authority. The requirements depend on the current use class, the proposed use, and local planning policies.Do I always need planning permission to change use?Not always. Some changes are permitted without a full planning application, while others require formal approval. Always check with your local planning authority before making changes.How do I check a property's planning category?You can review the property's planning history through your local council's planning portal, ask the seller or estate agent, or discuss the planning status with your solicitor during the purchase process.Is C1 or C3 planning use better for investment?Neither is automatically better. The right planning use depends on your investment strategy and how you intend to use the property.

Buying an HMO? Check These Room Sizes Before You Commit

The national HMO minimum room size standards in England require a bedroom occupied by one person over the age of 10 to measure at least 6.51m², whilst a room for two people over the age of 10 must be at least 10.22m². A room for one child under 10 must measure at least 4.64m², and any room smaller than this cannot be used as sleeping accommodation.Understanding the room sizes for HMO before you buy, renovate, or let a property helps you avoid costly mistakes and ensures your investment meets legal requirements from the start.What Are the Minimum Room Sizes for an HMO?Understanding the legal minimum room sizes should be one of your first checks. As per the guidance for local housing authorities, the current national standards are:OccupancyMinimum Room SizeOne person (aged 10 or over)6.51m²Two people (aged 10 or over)10.22m²One child (under 10)4.64m²Below 4.64m²Cannot be used as a bedroomThese are the legal minimum room sizes. Always check your local council's HMO licensing requirements, as higher standards may apply.HMO Minimum Room Size Rules: What Landlords MissMany landlords focus only on the room measurements and overlook other rules that affect whether a bedroom complies with HMO licensing standards. Some common mistakes are:Ceiling height affects the measurementOnly the floor area where the ceiling height is more than 1.5 metres counts towards the room size. It is needed for rooms with sloping ceilings, where part of the floor space may not be included in the official measurement.Local councils may require larger roomsThe national standards are the legal minimum, but they don't override local licensing conditions. Some councils require larger bedrooms or additional communal living space before granting an HMO licence. Room layout mattersA bedroom might meet the required floor area but still be impractical because of awkward layouts, restricted headroom, or fixed features that reduce usable living space. Legal Minimum Doesn't Always Mean Best InvestmentMeeting the HMO minimum room size rules doesn't automatically mean you've bought the best investment.Imagine you're comparing two similar HMOs in the same neighbourhood.The first property has bedrooms that meet the legal minimum. The second offers slightly larger rooms with better layouts and more storage space.Although both properties comply with the regulations, the second may attract stronger tenant demand, achieve higher rents, and experience fewer void periods because tenants often value comfort as much as location.National Standards vs Local Council RequirementsOne of the biggest mistakes landlords make is assuming the national rules are the only standards they need to meet.The national HMO minimum room size regulations set the legal baseline across England. However, local HMO standards can apply additional licence conditions that require larger bedrooms, extra communal space, or different occupancy limits.National StandardsLocal Council RequirementsApply across EnglandVary between local authoritiesSet the legal minimum room sizesMay require larger bedrooms or additional amenitiesCannot be lower than the statutory minimumCan introduce higher standards through HMO licensing conditionsMeeting the national minimum doesn't automatically mean your property will satisfy local licensing requirements.How Cribs Estates Helps HMO InvestorsCribs Estates has been helping landlords identify investment opportunities for over a decade.

Whilst the room itself may include an en-suite, some local authorities exclude the floor area occupied by personal washing facilities when assessing usable bedroom space. Always check your council's HMO standards before relying on the total room measurement.Can councils require larger HMO bedrooms?Yes. The national standards are the legal minimum, but local authorities have the power to apply higher room size standards through HMO licence conditions where appropriate.What happens if one bedroom is below the minimum size?A room measuring less than 4.64m² cannot be used as sleeping accommodation in a licensed HMO. Depending on the circumstances, it may need to be used for another purpose, such as storage or a study, rather than as a bedroom.How are HMO rooms measured?Measurements are taken from wall to wall, but only floor space where the ceiling height exceeds 1.5 metres is included. Sloping ceilings and unusable areas may reduce the official room size, so it's important to measure carefully before purchasing or converting a property.
