The Ultimate Guide to UK Landlord Tax (2026)

Being a landlord can look deceptively simple.

You collect rent, pay the mortgage, cover repairs and hopefully have some money left over at the end of the month.

But your rental profit, cash profit and taxable profit are not necessarily the same thing.

This is one of the biggest reasons landlords are sometimes surprised by their tax bills.

Mortgage repayments, capital improvements, furniture purchases and other costs may affect your cash flow without necessarily reducing your taxable rental profit in the way you expect.

And with different rules applying depending on whether you own property personally or through a limited company, getting the structure right can make a significant difference over the long term.

This guide explains the key UK landlord tax rules for 2026/27, including Income Tax, mortgage interest, Section 24, allowable expenses, capital allowances, Capital Gains Tax, limited companies, Inheritance Tax and exit planning.

Important: Tax rules can change and the correct treatment depends on your circumstances. This guide is for general information and should not be treated as personal tax advice.

How is rental income taxed in the UK?

If you own residential property personally, your rental income is generally taxed as part of your property business.

You calculate your taxable property profit broadly by taking your rental income and deducting allowable expenses.

However, not every cost associated with your property is deductible from rental income.

For example:

• letting agent fees may be deductible;

• property insurance may be deductible;

• qualifying repairs may be deductible;

• accountant's fees relating to the property business may be deductible;

• mortgage interest is subject to special rules for individual residential landlords;

• capital improvements are generally not deductible as revenue expenses.

HMRC generally treats the rental activities of an individual as a property business rather than as a normal trading business.

Most individual property businesses use the cash basis unless they elect to use traditional accounting rules and are eligible to do so.

Income Tax rates for landlords in 2026/27

For landlords in England, Wales and Northern Ireland, the standard Income Tax rates for 2026/27 are:

The Personal Allowance is reduced by £1 for every £2 of adjusted net income above £100,000, meaning it can be completely lost once income reaches £125,140.

These thresholds apply to your overall taxable income, not simply your rental income.

That means a landlord with employment income of £45,000 and rental profits of £15,000 may already have much of their rental income falling into the higher-rate tax band.

This is one reason landlord tax planning needs to consider your whole financial position, rather than looking at the property in isolation.

What counts as rental income?

Rental income is more than simply the monthly rent received from your tenant.

Depending on the circumstances, your property income calculation can include:

• rent;

• premiums for leases;

• certain payments made by tenants;

• payments for services;

• certain insurance receipts;

• other income connected with exploiting the property.

You should therefore keep proper records of all amounts received in connection with the property.

Do not assume that only the amounts labelled "rent" on your bank statement matter.

Which landlord expenses are tax deductible?

One of the most important principles is that an expense generally needs to be incurred wholly and exclusively for the property business and must be revenue rather than capital expenditure.

Common allowable expenses can include:

Letting agent and management fees

Fees paid to letting or property management agents are generally deductible where they relate to the rental business.

Insurance

Insurance covering risks such as:

• damage to the property;

• damage to contents;

• loss of rent;

can generally qualify as an allowable expense where it relates to the property business.

Repairs and maintenance

Routine repairs are generally deductible.

Examples include:

• repairing a leaking roof;

• replacing broken windows;

• repainting;

• repairing doors;

• repairing gutters;

• treating damp;

• repairing appliances.

HMRC distinguishes repairs from improvements.

A repair generally restores an asset to its previous condition, whereas an improvement may create something better or substantially different from what was there before.

Professional fees

Certain professional costs can be deductible where they relate to the ongoing property business.

This can include appropriate:

• accountancy fees;

• tax advice;

• property management fees;

• legal costs associated with qualifying lettings.

However, costs relating to acquiring or disposing of a property are often capital rather than revenue expenses.

For example, legal and professional costs connected with purchasing an investment property generally cannot simply be deducted from rental income.

Other common expenses

Depending on the circumstances, allowable expenses may also include:

• Council Tax paid by the landlord;

• utilities paid by the landlord;

• cleaning;

• gardening;

• service charges;

• ground rent;

• advertising;

• certain travel expenses;

• costs of running the property business.

HMRC's guidance specifically identifies items such as letting agent fees, qualifying legal fees, accountancy fees, insurance, repairs, utilities, ground rent, service charges and Council Tax as examples of potentially allowable expenses.

Repairs vs improvements: one of the biggest landlord tax traps

This distinction is extremely important.

Imagine you purchase a property that needs decorating.

You repaint the property and replace damaged flooring with equivalent flooring.

That may be a revenue repair/maintenance cost.

But if you fundamentally upgrade the property by installing substantially superior materials or changing its nature, some or all of the expenditure may be capital.

Capital expenditure generally cannot simply be deducted from rental income.

However, capital expenditure may potentially be relevant when calculating Capital Gains Tax on a future disposal or may qualify for capital allowances in circumstances where the legislation permits them.

The answer depends on exactly what you purchased and what work was undertaken.

Mortgage interest and Section 24

Mortgage interest is one of the areas that causes the most confusion for individual landlords.

For residential properties owned personally by individuals, mortgage interest is not normally deducted from rental income in the same way as ordinary allowable expenses.

Instead, the finance cost restriction gives qualifying individual landlords a basic-rate tax reduction.

The rules were phased in from 2017/18 and became fully effective from 2020/21.

Today, broadly speaking, the tax reduction is calculated at 20% of the relevant finance costs, subject to the statutory restrictions and calculation rules.

Example

Suppose:

• Rental income: £30,000

• Allowable expenses excluding finance costs: £5,000

• Mortgage interest: £10,000

Your property profit before finance costs is:

£30,000 − £5,000 = £25,000

You do not simply deduct the £10,000 mortgage interest to arrive at £15,000 taxable property profit.

Instead, the finance cost is dealt with under the Section 24 rules.

Subject to the detailed calculation, £10,000 of qualifying finance costs could generate a basic-rate tax reduction of up to:

£10,000 × 20% = £2,000

This is why a landlord can have relatively modest cash profit but still have a significant Income Tax liability.

Why Section 24 matters more to higher-rate taxpayers

The practical impact of Section 24 can be particularly significant for higher-rate taxpayers.

Before the restriction, a landlord paying tax at 40% could potentially obtain relief for mortgage interest at their marginal tax rate.

The current system generally limits the finance-cost tax reducer to 20%.

This does not mean that a landlord simply "loses 40% tax relief".

The precise calculation depends on total income, property profits, finance costs and other factors.

But it can substantially change the economics of highly leveraged personally owned property.

This is one of the reasons landlords should assess their financing and ownership structure before aggressively increasing borrowing.

For a more detailed explanation, see our guide:

Section 24 Explained Simply: How Mortgage Interest Tax Relief Works for Landlords.

Can landlords claim the cost of furniture?

Yes - but the rules are more specific than many landlords realise.

For residential landlords, the replacement of certain domestic items can qualify for Replacement of Domestic Items Relief.

This can include qualifying replacements such as:

• sofas;

• beds;

• tables;

• curtains;

• carpets and rugs;

• fridges;

• freezers;

• washing machines;

• crockery;

• kitchen equipment.

The rules generally concern replacement, rather than the initial purchase of domestic items.

The replacement must also generally be of broadly equivalent standard rather than an improvement, subject to the detailed legislation.

Fixtures such as baths, toilets, washbasins and certain fitted items are treated differently.

This is an area where keeping invoices and understanding the difference between a domestic item, fixture, repair and capital improvement is particularly important.

Capital allowances for landlords

Capital allowances are often misunderstood by residential landlords.

The cost of buying the property itself is not normally a capital allowance.

For a standard residential property business, capital expenditure is generally not deductible simply because it is capital expenditure.

There are, however, specific capital allowances that may apply to certain types of property expenditure.

The Structures and Buildings Allowance (SBA) can be relevant to qualifying expenditure on certain non-residential structures and buildings.

Plant and machinery allowances can also apply in appropriate circumstances.

However, the rules for ordinary residential property are not the same as the rules for commercial property or a trading business.

There is another important change landlords need to know about:

The Furnished Holiday Let rules were abolished

The special Furnished Holiday Letting regime ceased to apply from:

• 6 April 2025 for Income Tax and Capital Gains Tax;

• 1 April 2025 for Corporation Tax.

This means landlords should not rely on older online articles claiming that FHLs automatically receive the historic capital allowances and CGT advantages.

Personal ownership vs limited company ownership

One of the biggest decisions for property investors is whether to purchase property:

Personally, or

Through a limited company.

Neither structure is automatically better.

A company may be attractive because:

• Corporation Tax rates can be lower than higher-rate personal Income Tax in some circumstances;

• finance costs are generally dealt with under the company tax rules rather than the individual Section 24 restriction;

• profits can potentially be retained within the company for reinvestment;

• ownership can be structured for long-term portfolio growth.

However, companies also introduce additional considerations:

• Corporation Tax;

• company administration;

• annual accounts;

• confirmation statements;

• extracting profits;

• dividend taxation;

• financing costs;

• SDLT;

• potential tax on future extraction;

• CGT when shares are eventually disposed of;

• mortgage availability and commercial lending terms.

For 2026/27, Corporation Tax is generally 19% for companies with profits of £50,000 or less, 25% above £250,000, with Marginal Relief potentially applying between those thresholds. The thresholds are reduced where a company has associated companies.

The important point is:

A lower Corporation Tax rate does not automatically mean a limited company produces a lower overall tax bill.

The tax on extracting money personally needs to be considered too.

Capital Gains Tax when selling a rental property

When an individual sells or disposes of an investment property, a Capital Gains Tax calculation may be required.

Broadly, the gain starts with:

Sale proceeds

less:

Purchase cost

less:

Qualifying acquisition/disposal costs

less:

Qualifying capital expenditure

less:

Available reliefs and allowable losses

The resulting gain may be subject to CGT.

For 2026/27, the individual annual exempt amount is £3,000.

Residential property gains are generally subject to the applicable residential CGT rates depending on the taxpayer's circumstances and available Income Tax band.

The calculation can become significantly more complicated where the property:

• was previously your main residence;

• has been rented for part of the ownership period;

• has been inherited;

• has been transferred between spouses;

• has been transferred to a company;

• has been jointly owned;

• has had substantial improvements.

Private Residence Relief

If your rental property was previously your main home, you may be entitled to some Private Residence Relief.

This can reduce the taxable gain attributable to periods when the property qualified as your main residence.

The calculation can be complex and depends on the facts.

For example, you may need to consider:

• the dates you occupied the property;

• whether it was genuinely your main residence;

• periods of absence;

• the final-period rules;

• letting history;

• ownership structure.

Do not assume that simply living in a property for a period makes the entire gain tax-free.

Transferring a rental property to a limited company

Landlords sometimes assume that they can simply transfer an existing property into a company and start benefiting from corporate tax treatment.

It is rarely that simple.

A transfer can potentially create:

Capital Gains Tax

For CGT purposes, transferring an investment property to your own company can potentially be treated as a disposal at market value.

That can create an immediate taxable gain.

Stamp Duty Land Tax

SDLT can also arise depending on the circumstances and consideration involved.

Companies purchasing residential property are subject to the higher-rate rules in appropriate circumstances. HMRC confirms that purchases of major interests in dwellings by companies can fall within the higher rates where the statutory conditions are met.

Incorporation Relief

In certain circumstances, incorporation relief under TCGA 1992 s162 can defer a capital gain where a person transfers a qualifying business to a company in exchange for shares.

However, this is not an automatic exemption for every landlord who incorporates.

HMRC's guidance states that the relief can apply where a person transfers a business as a going concern, together with its assets (subject to the statutory conditions), to a company in exchange wholly or partly for shares.

The key question is therefore not simply:

"Do I own rental properties?"

It is:

"Does my property activity amount to a business that satisfies the conditions for the relief?"

This should be reviewed before any transfer takes place.

Inheritance Tax and rental properties

Rental property can form a significant part of an individual's estate.

For 2026/27, the standard Inheritance Tax nil-rate band is £325,000.

The Residence Nil-Rate Band is £175,000 where the relevant conditions are met, including the rules concerning a qualifying residence passing to direct descendants.

The Residence Nil-Rate Band is subject to a taper for larger estates, beginning at £2 million.

A qualifying estate may therefore potentially benefit from up to £500,000 of combined nil-rate bands, subject to the detailed rules.

A married couple or civil partners may potentially have transferable allowances, meaning the combined position can be significantly larger.

However, investment properties are not automatically protected from Inheritance Tax.

This makes estate planning particularly important for landlords with substantial property portfolios.

Should landlords use a company for Inheritance Tax planning?

A limited company can change the nature of the asset owned.

Instead of personally owning several properties, the individual may own shares in a company that owns the properties.

That does not automatically remove the value from the estate.

The shares themselves may form part of the individual's estate.

There are also complex rules around Business Property Relief and investment businesses.

Historically, some landlords have assumed that simply placing a property portfolio into a company automatically creates an IHT advantage.

That is far too simplistic.

Inheritance Tax planning should therefore be considered alongside:

• ownership;

• financing;

• gifting;

• succession;

• share structure;

• business activity;

• lifetime transfers;

• trusts;

• family circumstances.

This is an area where specialist advice may be required.

Common landlord tax mistakes

Some of the most common mistakes we see include:

Mistake 1 - Treating mortgage repayments as an expense

The capital repayment of a mortgage is not an allowable rental expense.

Mortgage interest is subject to the separate finance-cost rules.

Mistake 2 - Deducting improvements as repairs

Replacing something with a substantially better or different asset can be capital expenditure rather than a revenue repair.

Mistake 3 - Assuming every property expense is deductible

An expense needs to satisfy the relevant tax rules.

Personal expenditure cannot simply be put through the property business.

Mistake 4 - Ignoring Section 24

Landlords sometimes calculate:

Rent − all expenses − mortgage payment = taxable profit

That is not the correct calculation for an individual residential landlord.

Mistake 5 - Incorporating without modelling the tax

Transferring an existing property to a company can trigger SDLT and CGT.

Mistake 6 - Relying on old FHL advice

The special FHL regime was abolished from 2025.

Mistake 7 - Forgetting CGT when planning an exit

A property can generate a substantial capital gain even where monthly rental cash flow has been modest.

Mistake 8 - Keeping poor records

Missing invoices can mean missing legitimate deductions.

How to reduce landlord tax legally

Good tax planning is not about hiding income or inventing expenses.

It is about making sure the structure and claims reflect the legislation.

Depending on your circumstances, legitimate planning can include:

• claiming all allowable property expenses;

• correctly identifying repairs;

• claiming Replacement of Domestic Items Relief where available;

• reviewing ownership between spouses;

• considering the timing of disposals;

• using available CGT losses;

• reviewing mortgage and finance arrangements;

• modelling personal versus company ownership before buying;

• considering whether profits should be retained within a company;

• planning property acquisitions as part of the wider portfolio;

• considering estate planning;

• keeping accurate records from day one.

The best tax strategy is usually the one that fits the investment strategy, rather than chasing the lowest tax rate in isolation.

What about remortgaging?

Remortgaging can make financial sense for many landlords, but tax should form part of the decision.

The purpose of the borrowing matters.

For individual residential landlords, the finance-cost rules apply to qualifying residential property finance costs.

Where borrowing is increased, landlords should consider what the additional funds are being used for and whether the interest is attributable to the property business.

This is particularly important when extracting equity from one property to fund another investment.

A remortgage should therefore be assessed on:

Interest rate + fees + tax treatment + cash flow + investment return

rather than simply asking:

"Can I borrow more?"

Planning your landlord exit strategy

Tax planning should not begin when you decide to sell.

Ideally, your exit strategy should be considered when you acquire the property.

Different exit routes can produce very different tax outcomes.

Possible strategies may include:

Sell the property personally

This can create an individual CGT liability.

Retain the property for rental income

The property may continue generating income while potentially appreciating in value.

Transfer or incorporate

This may change the future tax treatment but can create immediate tax and transaction costs.

Pass assets to the next generation

This raises both lifetime gifting and Inheritance Tax considerations.

Sell shares in a property company

This can have a different tax profile from selling the underlying property, but the commercial and tax implications need to be modelled carefully.

There is no universal "best" exit strategy.

The landlord tax checklist

At least once a year, review:

☐ Total rental income

☐ Letting agent fees

☐ Repairs and maintenance

☐ Insurance

☐ Service charges

☐ Ground rent

☐ Council Tax and utilities paid by you

☐ Professional fees

☐ Replacement domestic items

☐ Mortgage interest and finance costs

☐ Capital expenditure

☐ Property improvements

☐ Ownership structure

☐ Mortgage structure

☐ Potential CGT exposure

☐ Previous residence history

☐ Property portfolio growth plans

☐ Estate and Inheritance Tax position

☐ Future exit strategy

A good landlord tax review should look beyond the current year's tax return.

The biggest question: are you optimising the portfolio or just filing the tax return?

There is a major difference between tax compliance and tax planning.

Compliance asks:

"What tax do I owe?"

Planning asks:

"What should I be doing now so that I don't create an unnecessary tax problem later?"

For a landlord with one property, the difference may be relatively small.

For someone building a portfolio, the decisions can become much more significant.

Buying personally versus through a company.

Using debt versus equity.

Remortgaging.

Buying another property.

Transferring an existing property.

Selling.

Gifting.

Passing assets to family.

Each decision can have tax consequences.

That is why property tax should be considered as part of the investment strategy rather than as an annual administrative exercise.

Final thoughts

There is no single "landlord tax rate".

Your overall tax position can be affected by:

• your employment or business income;

• rental profits;

• mortgage interest;

• allowable expenses;

• ownership structure;

• number of properties;

• Capital Gains Tax;

• previous occupation of the property;

• future investment plans;

• estate value;

• and your eventual exit strategy.

For some landlords, personal ownership remains perfectly sensible.

For others, a company structure may be worth considering.

For some, the biggest tax saving may simply be claiming expenses that have previously been missed.

And for others, the most valuable planning opportunity may be avoiding a costly transaction before it happens.

The important thing is to model the numbers before making the decision.

At SolutioRemote Accounting, we help landlords look beyond the tax return and understand how property income, financing, tax and longer-term investment decisions fit together.

If you're buying another property, considering incorporation, remortgaging, selling an investment property or simply want to know whether your current structure still makes sense, a landlord tax review can be a very worthwhile starting point.

Tax planning works best when it happens before the transaction - not afterwards.
