When a rental property is jointly owned by a married couple, civil partners, or unmarried co-owners, disclosing undeclared income through the Let Property Campaign raises a question that doesn’t come up for a sole landlord: how should the income actually be split between the owners for tax purposes? The answer depends heavily on your relationship status and how the property is legally owned, and getting it wrong can mean disclosing — and paying tax on — the wrong amounts for each person.

The Default Rule for Married Couples and Civil Partners

For married couples and civil partners who jointly own a property, HMRC’s default assumption is that rental income is split 50:50 between them for tax purposes, regardless of the actual ownership proportions or who does more of the practical management. This applies automatically unless the couple has taken specific steps to declare a different split.

Declaring an Unequal Split: Form 17

If a couple genuinely owns the property in unequal shares — for example, 70:30 — and wants their tax treatment to reflect that actual ownership split rather than the automatic 50:50 default, they need to make a formal declaration to HMRC using Form 17, along with evidence of the underlying unequal beneficial ownership, such as a declaration of trust. This election isn’t automatic or retrospective in the way some people assume — it only takes effect from the date HMRC receives a valid declaration, and can’t be backdated to earlier tax years where no such election was made.

This matters directly for a Let Property Campaign disclosure: if no Form 17 election was in place during the years being disclosed, HMRC will generally expect the 50:50 split to apply for those years, even if the couple’s actual ownership shares were different and even if they later put a valid election in place going forward.

Unmarried Couples and Other Joint Owners

The 50:50 default is specifically a rule for married couples and civil partners. For unmarried couples, siblings, friends, or other joint owners, rental income is generally taxed according to each person’s actual beneficial ownership share, which may or may not be an equal split, depending on how the property is legally and beneficially owned. This makes it particularly important for unmarried co-owners to establish the correct ownership percentages, ideally supported by a declaration of trust or similar documentation, before calculating each person’s disclosure.

What If Ownership Shares Have Changed Over Time?

It’s not unusual for ownership shares to change during the period covered by a disclosure — perhaps one partner bought out a larger share, or a property was transferred between spouses at some point. Where this has happened, the income split for each tax year needs to reflect the ownership position that actually applied during that specific year, rather than applying today’s ownership split retrospectively across the whole disclosure period.

Does Each Owner Need Their Own Disclosure?

Generally, yes. Each individual is separately responsible for reporting their own share of rental income to HMRC, which means each joint owner typically needs to make their own Let Property Campaign notification and disclosure, reflecting their own share of the income and their own personal tax position (including their own personal allowance, tax band, and other income). Our guide on joint tax disclosures covers the practical process of coordinating disclosures between joint owners.

Why the Split Matters for the Overall Tax Bill

Because Income Tax is charged on each individual separately, the way income is split between joint owners can genuinely affect the total tax bill for the household — particularly where one owner pays tax at a higher rate than the other, or where one owner has unused personal allowance. This is a legitimate area for forward-looking tax planning (via a genuine change in beneficial ownership and a Form 17 election), but for a historic disclosure, the split needs to reflect what actually applied during each year in question, not what would have been most tax-efficient with hindsight.

Married Couples Considering Tax-Efficient Ownership Going Forward

Once the historic disclosure is dealt with, some couples find it worth reviewing their ownership structure for future years, particularly where one spouse’s income sits in a lower tax band. Our guide on tax planning strategies for married couples and civil partners covers this in more detail, including how a Form 17 election and a change in beneficial ownership can work together going forward.

What Records You’ll Need

• Evidence of the legal and beneficial ownership structure — the title deeds, and any declaration of trust
• Any Form 17 elections made, and the effective date each one took effect
• Records of any change in ownership shares during the disclosure period
• Rental income and expense records, which can generally be shared between joint owners rather than duplicated

Our guide on property ownership structures in the UK is a useful companion resource for understanding how different ownership arrangements affect the tax position more broadly.

How Many Years Does Each Owner Need to Cover?

The look-back period is generally assessed per individual, based on their own circumstances and behaviour, rather than automatically applying the same number of years to both joint owners. In practice, since both owners are usually disclosing the same underlying property and income history, the years covered often end up aligned, but it’s worth confirming this rather than assuming. Our guide on how many years you need to declare sets out the general framework.

How Felix Accountants Can Help

We regularly help couples and joint owners work through exactly this kind of disclosure, correctly establishing the ownership split for each relevant year, preparing separate but coordinated disclosures for each individual, and making sure the numbers add up consistently across both. Get in touch to talk through your specific ownership situation.

Frequently Asked Questions

Is jointly owned rental income automatically split 50:50 between married couples?

Yes, by default, for married couples and civil partners, unless a valid Form 17 election has been made declaring a different split based on actual unequal ownership shares.

Can we backdate a Form 17 election to cover the years we’re disclosing?

No. A Form 17 election only takes effect from the date HMRC receives a valid declaration — it can’t be applied retrospectively to earlier tax years where no election was in place.

Does the 50:50 rule apply to unmarried couples too?

No. The 50:50 default is specific to married couples and civil partners. Unmarried co-owners are generally taxed according to their actual beneficial ownership shares.

Do both joint owners need to make separate Let Property Campaign disclosures?

Generally yes, since each individual is separately responsible for their own share of rental income and their own tax position, though the disclosures are usually coordinated to reflect the same underlying facts.

What if our ownership share changed partway through the years we’re disclosing?

The income split for each tax year should reflect the ownership arrangement that actually applied during that specific year, rather than applying the current ownership split retrospectively.

Running a limited company comes with a specific set of legal record-keeping obligations that go beyond what’s expected of a sole trader — partly because a company is a separate legal entity from its directors and shareholders, and partly because Companies House and HMRC each have their own requirements. Getting organised early makes year-end accounts, Corporation Tax returns, and any future due diligence considerably smoother.

Two Categories of Records: Statutory and Accounting

Limited company record-keeping falls into two related but distinct categories:

• Statutory records: company-level records required by Companies House, covering the company’s legal structure and governance
• Accounting records: financial records required by both Companies House (to prepare accurate statutory accounts) and HMRC (to support the Company Tax Return)

Directors are legally responsible for maintaining both, even where day-to-day bookkeeping is outsourced to an accountant or bookkeeper.

Statutory Records Every Company Must Maintain

• Register of members (shareholders)
• Register of directors and their service addresses
• Register of people with significant control (PSC register)
• Records of resolutions and minutes of general meetings and board decisions
• Register of charges, where the company has secured debt against its assets

Many of these are also filed at Companies House and kept up to date through the annual confirmation statement, but the company itself is still required to maintain its own internal registers, whether physically or digitally. Our company secretarial services cover the ongoing maintenance of these records if you’d rather not manage them in-house.

Accounting Records Every Company Must Maintain

Separately from the statutory registers, companies must keep sufficient accounting records to show and explain the company’s transactions, and to allow accurate financial statements to be prepared. In practice, this generally includes:

• Records of all money received and spent by the company, including the reason for each transaction
• A record of the company’s assets and liabilities, including what the company owns and owes
• Records of goods bought and sold, including invoices issued and received, for companies dealing in goods
• Stock records at the end of each financial year, where the company holds stock
• Details of stocktaking used to arrive at stock figures, where applicable
• Records supporting all business expenses claimed, including receipts and invoices, particularly for allowable limited company expenses

Bank Records

Every limited company should operate through its own dedicated business bank account, entirely separate from any director’s personal finances — this isn’t just good practice, it’s essentially required by the legal separation between a company and its owners. Bank statements form a core part of the accounting record trail, and regular bank reconciliation against your bookkeeping software helps catch errors early rather than at year end.

Director’s Loan Account Records

Where money moves between a director personally and the company outside of salary or dividends — for example, a director lending money to the company, or drawing money that isn’t yet formally declared as salary or dividend — this needs to be tracked carefully through a director’s loan account. Poor record-keeping here is a common source of problems, since an unclear or overdrawn director’s loan account can create unexpected tax charges, both for the company and the director personally.

Payroll Records

If the company has any employees, including directors paid a salary, payroll records need to be maintained separately, covering pay, tax and National Insurance deductions, and the underlying Real Time Information submissions made to HMRC. See our guide on small business payroll explained for what’s involved in running this correctly.

VAT Records, If Registered

VAT-registered companies have an additional layer of record-keeping requirements, including VAT invoices issued and received, and — under Making Tax Digital — digital records maintained through compatible software rather than manual spreadsheets alone. Our Making Tax Digital guide covers what this means in practice.

How Long Do Records Need to Be Kept?

For most companies, accounting records generally need to be retained for at least six years from the end of the relevant accounting period, though this can be longer in specific circumstances — for example, where the company buys something that it expects to last more than six years, such as equipment or property, or if the company is subject to an ongoing HMRC enquiry. It’s a sensible default to retain everything for at least six years even where a shorter minimum might technically apply, given how straightforward digital storage has become.

Choosing a Bookkeeping System

Beyond the legal minimum, most directors find that cloud accounting software, linked directly to the company bank account, makes ongoing compliance considerably easier than manual spreadsheets — particularly for VAT-registered companies needing Making Tax Digital compatibility, and for directors who want an accurate, real-time view of the company’s financial position rather than reconstructing it at year end.

What Happens If Records Aren’t Properly Maintained?

Failing to keep adequate accounting records is a company law offence, and directors can be personally liable for penalties or, in more serious cases, disqualification. Beyond the legal risk, poor records also make it far harder to prepare accurate statutory accounts and tax returns, increase accountancy costs (since more time is spent reconstructing information), and create real problems if the company is ever sold, audited, or subject to an HMRC enquiry.

How Felix Accountants Can Help

We help directors set up bookkeeping systems and statutory record-keeping processes that meet both Companies House and HMRC requirements from day one, whether that’s a fully managed bookkeeping service or guidance to help you manage it confidently yourself. See our wider business tax services for how well-organised records feed into accurate, efficient annual compliance.

Frequently Asked Questions

What’s the difference between statutory records and accounting records?

Statutory records relate to the company’s legal structure — shareholders, directors, and governance decisions. Accounting records relate to the company’s financial transactions, assets and liabilities, used to prepare accounts and tax returns.

How long must a limited company keep its accounting records?

Generally at least six years from the end of the relevant accounting period, though this can be longer in specific circumstances, such as an ongoing HMRC enquiry.

Do I need a separate bank account for my limited company?

Yes, effectively. A company is a separate legal entity from its directors, and its finances should be kept entirely separate from any director’s personal banking.

What is a director’s loan account and why does it need careful records?

It tracks money moving between a director personally and the company outside of formal salary or dividends. Poor record-keeping here can lead to unexpected tax charges if the account becomes unclear or overdrawn.

What happens if a company doesn’t keep proper accounting records?

It’s a company law offence, and directors can be held personally liable. It also makes accurate accounts and tax returns far harder to prepare, and creates problems for any future sale, audit or HMRC enquiry.

Owners of holiday cottages, coastal Airbnbs and other short-term let properties have historically benefited from more generous tax treatment than standard buy-to-let landlords. That changed significantly from April 2025, when the Furnished Holiday Lettings (FHL) tax regime was abolished. If you have undeclared income from a furnished holiday let, this shift makes it more important than ever to understand exactly which rules apply to which years — because the position before and after April 2025 is genuinely different, and a Let Property Campaign disclosure needs to reflect that.

What Was the Furnished Holiday Lettings Regime?

Until 5 April 2025, properties that qualified as Furnished Holiday Lets benefited from a range of tax advantages not available to standard residential lettings, including full relief for mortgage interest and other finance costs (rather than the restricted basic-rate credit that applies to standard buy-to-lets), the ability to claim capital allowances on furniture and equipment, treatment of profits as relevant earnings for pension contribution purposes, and access to certain Capital Gains Tax reliefs, including Business Asset Disposal Relief, on eventual sale.

What Changed From April 2025?

From 6 April 2025 for Income Tax and Capital Gains Tax (1 April 2025 for Corporation Tax), the FHL regime was abolished, and qualifying properties are now taxed in essentially the same way as any other residential letting. This means finance costs are now restricted to the basic-rate tax credit, new capital allowances claims have generally stopped (with “replacement of domestic items relief” available instead in many cases), and the favourable Capital Gains Tax treatment on disposal has been withdrawn other than in limited transitional circumstances.

Why This Matters for a Let Property Campaign Disclosure

If you’re disclosing undeclared income from a property that qualified as a furnished holiday let, the calculation needs to be split at the April 2025 boundary:

• For years up to and including 2024/25: if the property genuinely met the FHL qualifying conditions, the more generous FHL rules (full finance cost relief, capital allowances, etc.) would have applied
• For 2025/26 onwards: the property is taxed under the standard residential letting rules, meaning restricted mortgage interest relief and the other changes described above

Getting this split right matters because applying the wrong rules to the wrong years can significantly under- or over-state what’s owed. This is a more technical calculation than a standard buy-to-let disclosure, and it’s an area where professional advice is genuinely valuable.

Did Your Property Actually Qualify as an FHL?

Before assuming the FHL rules applied for earlier years, it’s worth checking whether the property genuinely met the qualifying conditions during those periods, which broadly required the property to be available for letting on a commercial basis for a set number of days per year, actually let for a minimum number of days, and not normally occupied by the same tenant for long continuous periods. A property let short-term through platforms like Airbnb doesn’t automatically qualify as an FHL simply because of how it was marketed — the specific letting pattern needs to be checked year by year.

Joint Ownership Changes Are Worth Checking Too

Another change worth being aware of: under the old FHL rules, jointly owned couples could flexibly allocate profits between themselves, reflecting who actually did the work, rather than following the strict ownership split. From April 2025, furnished holiday lets are subject to the same default rules as standard jointly owned property, generally a 50:50 split unless a valid election has been made. If your disclosure involves a jointly owned former FHL, this is worth reviewing carefully for the years either side of the change.

What About VAT for Short-Term Lets?

Separately from Income Tax, holiday accommodation is generally treated as a standard-rated supply for VAT purposes, unlike most long-term residential letting, which is typically exempt. If your short-term let income (combined with any other taxable turnover) exceeds the VAT registration threshold, VAT registration and reporting obligations may also need reviewing alongside the Income Tax disclosure. Our property tax guide covers how different letting types are treated for tax purposes more broadly.

Working Out How Many Years to Disclose

The look-back period for a Let Property Campaign disclosure is generally determined by the reason for non-disclosure rather than the type of letting involved, so the same principles apply to holiday lets as standard buy-to-lets. Our guide on how many years you need to declare sets out the general framework, though the added complexity of the FHL-to-standard-letting transition means the year-by-year calculation itself takes more care to get right.

What You’ll Need to Gather

• Booking records or platform statements showing income received each year
• Evidence of letting pattern (nights let, availability) to confirm FHL qualification for pre-2025/26 years
• Mortgage interest statements and records of capital expenditure on furniture and equipment
• Details of the ownership structure, particularly for jointly owned properties

How Felix Accountants Can Help

Disclosing undeclared income from a former furnished holiday let is genuinely more involved than a standard residential letting disclosure, given the rule change partway through the relevant period. We help holiday let owners establish which years qualified under the old FHL rules, apply the correct treatment either side of April 2025, and manage the disclosure process through our Let Property Campaign guide and wider disclosure services.

Frequently Asked Questions

Does the Furnished Holiday Lettings regime still exist?

No. It was abolished from 6 April 2025 for Income Tax and Capital Gains Tax purposes (1 April 2025 for Corporation Tax). Holiday let properties are now generally taxed in the same way as standard residential lettings.

Do I still get full mortgage interest relief on my holiday let?

Only for years up to and including 2024/25, if the property genuinely qualified as an FHL during those years. From 2025/26 onwards, mortgage interest relief is restricted to a basic-rate tax credit, the same as standard buy-to-let properties.

How do I know if my property actually qualified as an FHL in earlier years?

Qualification depended on meeting specific letting-pattern conditions each year, including availability and actual letting days. It’s worth reviewing this year by year rather than assuming qualification based on how the property was marketed.

Is holiday let income treated differently for VAT?

Yes. Holiday accommodation is generally standard-rated for VAT, unlike most long-term residential letting, which is usually exempt. This may create a separate VAT registration obligation if turnover exceeds the threshold.

Can I still use the Let Property Campaign for undeclared holiday let income?

Yes, the Let Property Campaign covers undeclared residential letting income generally, including furnished holiday lets, though the calculation needs to correctly reflect the rules that applied in each specific tax year.

If you used to let out a property but have since sold it, gifted it, or moved back in yourself, you might assume that any undeclared rental income from those years is now somehow out of reach of HMRC. It isn’t. The good news is that selling the property doesn’t close the door on putting things right — you can still use the HMRC Let Property Campaign to disclose rental income from a property you no longer own, and doing so voluntarily is almost always better than waiting to be found.

Does Selling a Rental Property Remove Your Obligation to Declare Past Rent?

No. Your obligation to report rental income relates to the tax years in which you actually received that income, regardless of whether you still own the property today. If you let out a property between, say, 2019 and 2023 and then sold it, you were still legally required to report the rent you received during those years on a Self Assessment tax return. Selling the property doesn’t erase that history — it simply means the disclosure now covers a property that no longer appears on your current asset list.

This is one of the most common misunderstandings we see at Felix Accountants. Landlords often believe that once a property is sold, any loose ends relating to it are automatically tidied up. In reality, HMRC’s Let Property Campaign was specifically designed to capture exactly this kind of situation — current landlords, former landlords, and anyone in between with unreported letting income.

Who Can Use the Let Property Campaign for a Former Rental Property?

The Let Property Campaign is open to individual landlords who have received undeclared rental income from residential property in the UK or abroad. This includes people who:

• Sold the rental property some years ago but never declared the rent received while they owned it
• Inherited a property, let it out for a period, and later sold it
• Moved back into a property that was previously let to tenants
• Gifted or transferred a rental property to a family member and stopped receiving rent from it
• Were an accidental landlord for a short period before selling

In every one of these cases, the fact that the property has moved on doesn’t change the underlying tax history. What matters to HMRC is the income you received while you owned and let the property, not whether you still hold the title today.

How Far Back Do You Need to Declare?

The look-back period depends on why the income wasn’t declared in the first place, not on when you sold the property. As a general guide:

• Genuine, careless error: typically up to 4–6 years
• Failure to take reasonable care: up to 6 years
• Deliberate non-disclosure: HMRC can go back as far as 20 years

We’ve written a more detailed breakdown of this in our guide on how many years you need to declare and our companion article on how many years of rental income landlords must disclose. If the property has since been sold, you’ll still need to work out the correct number of years based on when you first started letting it and when the undeclared income actually stopped, which for a sold property is usually the completion date.

What About Capital Gains Tax on the Sale Itself?

A disclosure through the Let Property Campaign covers rental income and any related expenses, not the sale of the property. However, if you sold the property at a profit, you may separately owe Capital Gains Tax on that sale, and UK residential property sales generally need to be reported to HMRC within 60 days of completion. If both the rental income and the sale itself were never reported, it’s sensible to deal with both matters together rather than treating them as separate problems, since HMRC will often be looking at your full history once a disclosure is opened.

Why Voluntary Disclosure Still Matters After the Sale

Coming forward voluntarily, before HMRC contacts you, generally results in significantly lower penalties than a prompted disclosure that follows an HMRC letter or enquiry. Our article on prompted versus unprompted disclosures sets out the practical difference in more detail, but the short version is this: HMRC has extensive data-matching capability drawn from Land Registry records, Stamp Duty Land Tax returns, letting agent reporting and platforms such as Airbnb, so a sold property is not invisible simply because you no longer own it. Making the first move, through our voluntary disclosure guidance, gives you more control over the outcome, the tone of the process and the penalty percentage applied.

What You’ll Need to Gather

Because you no longer own the property, you may not have easy access to the same records a current landlord would. It’s still worth trying to pull together:

• Bank statements showing rent received during the letting period
• Tenancy agreements or letting agent statements, if available
• Records of allowable expenses such as mortgage interest, insurance, repairs and letting agent fees
• The completion date of the sale, and the purchase and sale prices, in case a Capital Gains Tax position also needs reviewing

If some records are missing entirely, that’s a common and manageable problem — HMRC accepts reasonable estimates provided they’re clearly labelled and based on a sensible methodology, rather than guesswork presented as fact.

How Felix Accountants Can Help

We regularly help former landlords work through reporting undisclosed rental income to HMRC, including cases where the property has already been sold, gifted, or repossessed. We’ll help you reconstruct a reasonable income and expense history, calculate what’s owed, and manage the notification and disclosure process on your behalf so you’re not dealing with HMRC directly and unrepresented.

Frequently Asked Questions

Can I still be investigated if I sold the rental property years ago?

Yes. HMRC’s ability to open an enquiry into undeclared rental income isn’t affected by a subsequent sale. The tax liability relates to the years you received the income, and HMRC can pursue this regardless of your current ownership status.

Do I need to disclose if the rental profit was very small?

Generally yes. There’s no minimum threshold that exempts small amounts of rental profit from disclosure, although your allowable expenses and personal allowance may mean little or no tax is ultimately due once everything is calculated correctly.

What if I can’t find all my old records for a property I no longer own?

This is common, particularly for properties sold some years ago. HMRC accepts reasonable, clearly explained estimates where original records aren’t available. An accountant experienced with the Let Property Campaign can help you build a defensible estimate.

Will disclosing affect the sale I’ve already completed?

No. The sale itself is a separate, completed transaction. A Let Property Campaign disclosure deals with the historic rental income tax position and won’t unwind or affect the property sale.

Is it too late to make a voluntary disclosure?

It’s rarely too late to disclose voluntarily unless HMRC has already contacted you about the specific property. Acting before any HMRC letter arrives keeps your disclosure classed as unprompted, which generally attracts lower penalties.
