Making Tax Digital (MTD) for Income Tax Self-Assessment is HMRC’s initiative to modernise how landlords report rental income. For commercial landlords, this marks a shift away from traditional annual Self-Assessment returns toward a system of digital record-keeping and regular online submissions throughout the tax year.
If you own commercial property such as offices, retail units, warehouses, or industrial premises, and receive rental income personally, MTD will eventually become mandatory for you once your income exceeds HMRC’s threshold. Rather than preparing accounts once a year, landlords will be required to keep their records digitally and submit quarterly updates to HMRC using compatible software.
It is important to understand that MTD does not change how commercial landlords are taxed. The rules on allowable expenses, capital allowances, and profit calculation remain broadly the same. What MTD changes is how and when information is reported, with HMRC gaining more frequent visibility over property income.
MTD for commercial landlords applies only to individuals. General partnerships are not yet mandated into MTD for Income Tax, although individual partners’ non-partnership income may still count towards the threshold.
Landlords operating through limited companies are not currently included and will fall under MTD for Corporation Tax at a later date. This distinction is crucial, as many commercial property owners assume MTD applies universally.
When Does MTD Apply to Commercial Landlords?
MTD for commercial landlords is being introduced in stages, based on the level of gross property income you receive each year. The timing is important because many landlords assume the rules apply only once profits reach a certain level, when in fact HMRC looks at total income before expenses.
From April 2026, commercial landlords with gross property income over £50,000 will be required to comply with MTD for Income Tax Self-Assessment. This includes all rental receipts from commercial property, as well as any other taxable income linked to the property, such as service charges or insurance recharges. These amounts form part of HMRC’s definition of “qualifying income”, which is assessed before expenses are deducted.
From April 2027, the threshold will reduce to £30,000, bringing many more small and mid-sized commercial landlords into scope.
From April 2028, the threshold will reduce further to £20,000, meaning a significantly wider group of commercial landlords will be required to comply.
It is also important to note that the threshold applies to each individual, not to each property. If you own multiple commercial units, the income from all of them is added together. For jointly owned properties, each owner must separately assess their share of the revenue to determine whether they meet the threshold.
Landlords with income below the threshold can still choose to join MTD voluntarily, but there is no obligation to do so until the relevant income level is exceeded.
What Actually Changes Under MTD for Commercial Landlords?
For commercial landlords, MTD represents a structural change in how property income is managed, rather than a change in the underlying tax rules. Many landlords are used to gathering bank statements and invoices after the tax year ends and dealing with their tax position in one go. MTD replaces this reactive approach with an ongoing digital compliance system.
The first major change is the requirement to keep digital records. Commercial landlords must record rental income, allowable expenses, and transaction dates in a digital format accessible to MTD-compatible software. While spreadsheets can still be used, they must be digitally linked to compliant software, meaning manual copying and pasting between systems will no longer be acceptable. For landlords with multiple commercial units, records must be organised clearly enough to show how income and expenses relate to each property.
The second major change is the introduction of quarterly reporting. Instead of submitting one annual tax return, commercial landlords must send summary updates to HMRC every three months. These updates show total income and expenses for the period and are submitted through approved software. Although these figures do not calculate the final tax due, they significantly increase the frequency of interaction with HMRC and require landlords to keep their records up to date throughout the year.
Finally, MTD changes the overall compliance timeline. At the end of the tax year, commercial landlords must submit a Final Declaration that includes all income sources and any adjustments such as capital allowances or accruals. This replaces the traditional Self-Assessment return and makes tax compliance a continuous process rather than a single annual deadline.
For many commercial landlords, particularly those with larger portfolios or complex lease arrangements, this shift will require new systems, better record discipline, and earlier involvement from accountants to avoid errors and late submissions.
How Quarterly Reporting Works for Commercial Landlords

Under MTD, commercial landlords are required to submit quarterly updates to HMRC, a process that marks a significant departure from the traditional annual Self-Assessment. These updates are not full tax returns; they are summaries of income and expenses, but they form the backbone of HMRC’s real-time view of a landlord’s property business.
Each quarter, landlords must report the total rental income received and the total allowable expenses incurred. This includes rent, service charges, insurance recharges, repairs, and other costs directly associated with managing commercial property. The updates must be submitted using MTD-compatible software, which can include accounting platforms or approved spreadsheet systems that link directly to HMRC.
The timing of quarterly updates aligns roughly with the UK tax year: April–June, July–September, October–December, and January–March. Submitting these updates on time is essential, as they provide HMRC with ongoing visibility into the landlord’s financial position and reduce the risk of year-end surprises. While the updates do not calculate the final tax liability, they allow landlords to monitor their position and make planning adjustments throughout the year.
At the end of the tax year, landlords use the quarterly updates as the foundation for their Final Declaration. Any additional adjustments, such as capital allowances or prepaid expenses, are included at this stage. By moving to quarterly reporting, MTD encourages commercial landlords to maintain up-to-date, accurate records throughout the year, rather than leaving accounting and tax preparation until the last minute.
For landlords managing multiple commercial properties, quarterly reporting also requires tracking income and expenses by property, ensuring that each unit’s profitability and tax obligations are clearly documented. Many landlords find that integrating property management systems with MTD-compliant accounting software simplifies this process, reducing the risk of mistakes and penalties.
Allowable Expenses & Capital Allowances for Commercial Landlords
While MTD changes how commercial landlords report their income, it does not alter what expenses or allowances can be claimed. Understanding allowable expenses and capital allowances is essential to ensure you pay the correct tax and take full advantage of deductions.
Allowable Expenses
For commercial landlords, allowable expenses are generally costs that are wholly and exclusively incurred in managing, maintaining, or renting out a commercial property. Common examples include:
Accurate categorisation of expenses is crucial under MTD, as HMRC expects digital records to clearly link each expense to the property to which it relates. Landlords with multiple units or tenants may need to allocate shared costs proportionally to avoid errors.
Capital Allowances
Commercial landlords may also claim capital allowances for certain assets, which allow part of the cost of eligible fixtures and equipment to be deducted from rental profits. Examples include:
Capital allowances require careful record-keeping, as the deductions are made over time rather than in a single year. Under MTD, these allowances must be reported in the Final Declaration.
Why This Matters for MTD
MTD encourages real-time monitoring of income and expenses, which makes it easier for landlords to identify allowable deductions throughout the year. Accurate quarterly reporting helps prevent under-claiming or over-claiming costs and reduces the risk of HMRC queries.
For landlords managing multiple commercial properties, tracking expenses per property is particularly important. Using MTD-compatible accounting software allows you to tag each expense correctly and ensures that all allowable deductions are captured without manual intervention at year-end.
Preparing for MTD
Transitioning to Making Tax Digital requires more than just new software; it requires a structured approach to record-keeping, planning, and compliance. For commercial landlords, preparing early can save time, reduce errors, and avoid penalties.
Assess Your Income & Portfolio
Start by reviewing your gross property income to determine when MTD will apply. Remember, HMRC looks at total income before expenses, including rent, service charges, and insurance recharges. If your portfolio is jointly owned, calculate your share of the income separately. Understanding your threshold status early helps you plan the transition smoothly.
Choose MTD-Compatible Software
MTD requires digital record-keeping through approved software. Popular options range from cloud-based accounting systems to spreadsheet solutions that integrate with HMRC. The key is to ensure the software can:
Many landlords find that integrating property management systems with accounting software reduces manual work and keeps data accurate.
Organise Your Records
Under MTD, it’s essential to track all transactions per property. Set up clear categories for:
For landlords with multiple properties or tenants, tagging each transaction to the correct unit avoids confusion and ensures proper reporting.
Work With Professionals
While MTD does not change tax rates or allowable expenses, the reporting process is more frequent and structured. Working with an accountant experienced in commercial property taxation can help you:
Professional support also provides reassurance that your systems comply with HMRC requirements.
Keep Records Up to Date
The biggest shift under MTD is the move from year-end record-keeping to year-round compliance. Maintain digital records consistently and review them quarterly before submitting updates. Doing so prevents last-minute scrambling and ensures that your tax position is transparent and accurate throughout the year.
Plan for Capital Allowances
Commercial landlords often overlook capital allowances, which can significantly reduce taxable profits. Review potential claims early, keep detailed records, and incorporate them into your quarterly reporting. Software can help you track allowances over time rather than waiting until year-end.
By taking a proactive approach, commercial landlords can make the MTD transition smoother and more efficient. Early planning, accurate digital record-keeping, and professional guidance reduce the risk of mistakes, improve visibility over tax obligations and ultimately save time and stress when the end-of-year submissions arrive.
Conclusion: Navigating MTD as a Commercial Landlord
Making Tax Digital is changing how commercial landlords manage property income. While the tax rules remain the same, MTD requires year-round digital record-keeping, quarterly updates to HMRC, and a final year-end submission. Compliance is no longer a once-a-year task but an ongoing process.
Landlords need to understand the thresholds: from April 2026, gross income over £50,000 triggers MTD, and from April 2027, the threshold drops to £30,000. Income from multiple properties must be combined, and jointly owned properties are assessed separately for each owner.
Accurate recording of allowable expenses and capital allowances is essential. Repairs, insurance, professional fees, utilities, and mortgage interest can be deducted, and capital allowances for fixtures and machinery reduce taxable profits. Keeping records per property helps avoid mistakes.
Preparation is key: review income, choose MTD-compatible software, organise records, and work with accountants. By doing so, landlords can streamline reporting, avoid penalties, and gain better visibility of their tax position, making MTD a manageable part of running a commercial property portfolio.
