MTD Made Simple for Landlords with Jointly Owned Properties

Making Tax Digital (MTD) for Income Tax Self-Assessment changes how jointly owned rental property is reported to HMRC. While joint ownership often feels like a shared responsibility, MTD makes it clear that each joint owner is treated as a separate taxpayer, with their own reporting and compliance obligations.

Under MTD, joint ownership does not create a single tax profile for the property. Instead, HMRC looks at the individual landlord, not the property itself. This means that even where income is shared, managed by one person, or paid into a joint bank account, each owner must still keep their own digital records and submit their own information to HMRC.

MTD introduces ongoing digital compliance for joint owners, replacing the traditional once-a-year Self-Assessment process. Rather than submitting one annual return that includes property income, each owner will be required to keep digital records of their share of income and expenses and submit quarterly updates throughout the tax year using MTD-compatible software.

Crucially, MTD does not change how joint landlords are taxed or how income is split between owners. The rules on ownership percentages, allowable expenses and profit allocation remain the same. What changes is the frequency and the digital reporting of this information, making early understanding especially important for jointly owned properties.

When Does MTD Apply to Joint Ownership Landlords?

For jointly owned properties, the timing of Making Tax Digital is determined by each owner, not by the property. This is one of the most misunderstood aspects of MTD and often catches joint landlords by surprise.

MTD for Income Tax Self-Assessment applies based on your individual share of gross qualifying income (before expenses) from property and/or self-employment, not on the total rent generated by the property alone.

From April 2026, MTD becomes mandatory if your individual share of gross income exceeds £50,000. From April 2027, this threshold drops to £30,000, bringing many more joint owners into scope. From April 2028, the threshold is scheduled to reduce further to £20,000.

To clarify, if a property earns £90,000 a year and is owned equally by two people, each owner has £45,000 of gross income. In this case, neither owner would be required to comply with MTD in 2026, but both would fall within scope from 2027. The key point is that each owner must assess their position separately, even though the property income is shared.

When an individual owns multiple jointly owned properties, their income share across all properties must be aggregated to determine whether the MTD threshold is met. This aggregation should also include any other qualifying self-employment income held by the individual.

It is therefore possible for one joint owner to be within MTD while another is not, depending on their wider income.

Landlords whose income remains below the threshold can still choose to join MTD voluntarily. But, please note that there is no requirement to do so until their individual income exceeds the relevant limit set by HMRC.

How Digital Record-Keeping Works for Joint Ownership Landlords

Under Making Tax Digital, joint ownership does not allow landlords to rely on a single shared set of records. Each joint owner must keep their own digital records showing their share of rental income and allowable expenses, even if the property is managed by one person or through a joint bank account.

In practical terms, this means that while joint owners can use the same bookkeeping system or spreadsheet, the records must clearly show how income and expenses are split between owners. HMRC expects each landlord’s figures to be identifiable and reportable on an individual basis, rather than being divided manually at the end of the year.

For joint landlords with multiple properties, good record-keeping becomes even more important. Income and expenses should be tracked per property and per owner, ensuring that each landlord’s quarterly updates and year-end submissions accurately reflect their share. Setting this up correctly from the outset significantly reduces the risk of errors, missed submissions and HMRC enquiries later on.

Quarterly Reporting for Joint Ownership Landlords

Making Tax Digital introduces quarterly reporting, and for jointly owned properties, this obligation applies separately to each owner. Even if the rental income is shared or managed centrally, HMRC requires individual quarterly submissions from every joint landlord within MTD.

These figures are reported using MTD-compatible software and must reflect the ownership split set out in the legal or beneficial ownership of the property. There is no option for one owner to submit on behalf of all owners, and one person’s compliance does not cover the other.

However, quarterly updates are interim and do not determine final tax liability. The Final Declaration (submitted after the tax year end) confirms the final taxable position.

But quarterly updates do form part of HMRC’s compliance record and late or missing submissions may lead to penalties.

A common challenge for joint landlords is where one owner receives the rent into their bank account and pays the expenses. Under MTD, this does not change the reporting requirement. Each owner must still submit their own quarterly update based on their share, even if the cash flow is controlled by someone else.

To manage this effectively, many joint landlords rely on shared software that automatically allocates income and expenses by ownership percentage, ensuring each person’s quarterly submission is accurate and consistent.

Common Challenges Joint Landlords Face Under MTD

Jointly owned landlords often face unique challenges when adapting to Making Tax Digital. Unlike sole landlords, compliance responsibilities are split across individuals, which can create confusion if clear processes are not in place.

One of the most common issues is assuming that a single quarterly update or year-end submission covers all owners. Under MTD, each owner must submit their own updates, even if one person manages the property, receives rent or pays expenses. Failure by any one owner can result in penalties and unnecessary HMRC scrutiny for that individual, regardless of the other owners’ compliance.

Another challenge is accurately splitting income and expenses. Joint landlords must track their respective shares of rent, repairs, insurance and professional fees according to their ownership percentages. Inconsistent record-keeping, mixed bank accounts or poorly documented expense allocations can easily lead to errors in quarterly updates and final submissions.

Threshold calculations also create complexity. If owners have multiple jointly held properties, each person’s combined share of gross income must be assessed separately. One owner can meet the MTD threshold while another does not, which can cause misunderstandings if the group assumes a uniform approach.

Finally, many joint landlords struggle with software and digital record-keeping. Using non-MTD-compliant spreadsheets or systems that don’t allow clear allocation between owners can lead to mistakes, duplicated work, and delays. Selecting software that supports multiple owners and automated allocation is critical for smooth compliance.

Preparing for MTD as a Joint Ownership Landlord

Preparation is crucial for joint ownership landlords to comply with Making Tax Digital smoothly. Since each owner is individually responsible, clear systems and processes are essential to avoid mistakes and ensure accurate reporting.

1. Confirm Ownership Shares & Income Splits

Start by reviewing the legal ownership of each property. Ensure each landlord’s share of rental income and expenses is clearly defined. This is critical because each owner will submit their own quarterly updates and Final Declaration, reflecting only their portion of revenue and allowable costs.

2. Choose the Right Software

MTD requires approved digital record-keeping software. For joint owners, it is especially important to select systems that allow:

RentalBux is a property-focused platform that supports joint ownership, simplifies income and expense allocation, and ensures compliance with MTD requirements. Using software like this reduces manual calculations and minimises the risk of reporting errors.

Keep detailed digital records of rental income, expenses and capital allowances for each owner and property. Shared spreadsheets may be used only if they are digitally linked to HMRC-recognised MTD-compatible software via bridging software and clearly separate each owner’s data.

Accurate record-keeping forms the basis of quarterly updates and the Final Declaration.

Professional guidance is especially important for landlords with multiple properties or complex ownership arrangements.

5. Keep Records Up-to-Date

MTD transforms compliance into a year-round obligation. Keeping records updated quarterly prevents errors, ensures accurate reporting in the Final Declaration and reduces the risk of HMRC queries or penalties.

Conclusion

Making Tax Digital brings a new approach for joint ownership landlords, where each owner is individually responsible for compliance. Even if one person manages the property or receives all rental income, every joint owner must keep their own digital records, submit quarterly updates, and complete the Final Declaration accurately. This year-round process requires careful planning, clear record-keeping and attention to ownership shares to ensure income and expenses are correctly allocated and reported.

Using excellent software like RentalBux can significantly ease compliance, automatically splitting income and expenses according to ownership shares and ensuring that updates are submitted correctly to HMRC. By establishing consistent record-keeping practices, reviewing allowable expenses and capital allowances, and seeking professional guidance if needed, joint landlords can navigate MTD confidently, minimise errors, and maintain clear oversight of their property income and tax obligations throughout the year.
