Financial record-keeping is seldom a landlord’s passion project, but records hold the answers to many questions.
Is that property actually profitable? Which expenses are increasing? And what happens during an HMRC investigation?
Now, with Making Tax Digital (MTD) due to roll out for self-assessment taxpayers—including many landlords—from 2026, the days of cobbling together property finances once a year are numbered.
HMRC, which is ramping up penalties and hiring more compliance staff, will receive more frequent digital submissions through the MTD system, potentially making it easier for them to identify discrepancies and target investigations more efficiently.
Let’s take a closer look at the implications of switching to digital records under the MTD system and how this will interact with HMRC tax investigations.
HMRC Investigations For Landlords
Tax investigations are becoming increasingly common for ordinary landlords who simply make mistakes or have inconsistent records.
In 2022-23, government figures suggest that compliance activities yielded £34 billion from tackling avoidance, evasion, and errors, with property investors frequently in their crosshairs.
When HMRC decides to take a closer look at your clients’ property income, they typically use one of three approaches:
- Aspect inquiries, which focus on specific items that raise questions. These targeted reviews usually conclude within six months if your client can provide the documentation to support their claims.
- Full investigations that dig deeper into your client’s complete tax situation. HMRC examines property income alongside all other financial activities, including business and personal accounts. The goal? To verify that their tax return accurately reflects their true financial position. These comprehensive reviews typically stretch across 12-18 months.
- Random checks, where HMRC selects a sample of returns regardless of any indicators, partly as a compliance measure and partly to test their own systems. Despite the “random” label, these reviews require the same thorough documentation as any targeted investigation.
The triggers for these vary widely. Sudden changes in reported income, unusually high expense claims, or frequent late submissions can all catch HMRC’s attention.
HMRC’s Penalty Regime
MTD for ITSA mandates digital record-keeping for the vast majority of taxpayers it applies to. It imposes its own penalty regime for late submissions and payments, which will stack with HMRC’s existing regime for handling non-compliance.
When HMRC investigates and finds mistakes in a tax return, they don’t just collect the unpaid tax – they add penalties based on behaviour. Even careless mistakes (like misplacing receipts or mixing up expenses between properties) typically result in penalties of 15-30% on top of the tax owed. If HMRC believes errors were deliberate, penalties can reach 100% of the unpaid amount.
As noted, the MTD system introduces a different set of penalties. Landlords receive points for missed submission deadlines, with financial penalties of £200 once they reach a certain threshold.
It’s a case of double jeopardy. The same disorganised records that make it hard to file accurate tax returns also make it difficult to meet MTD deadlines consistently, and can land clients in hot water in the event of an investigation.
MTD and HMRC: A New Era of Visibility
One of MTD’s main features is that it establishes digital record-keeping with quarterly reporting requirements, giving HMRC greater insight into landlords’ finances.
Every transaction must be properly recorded and categorised in MTD-compatible software. With this, it may be quicker and easier for HMRC to cross-reference submissions.
For compliant landlords using good digital systems, this will reduce investigation risk – it’s a more robust, transparent system than the existing self-assessment system. When your quarterly figures consistently match expected patterns and third-party data, HMRC has fewer reasons to look closer.
Digital Records are a Business Asset
Digital records accomplish considerably more than just satisfying HMRC requirements.
For both accountants and their landlord clients, adopting MTD-compliant systems provides insights that transform property management:
- They reveal true property performance: When all expenses are properly allocated, it becomes clear which properties are genuinely profitable and which require attention. This drives better decisions about rents, improvements, or potential sales.
- They identify emerging cost issues: Digital systems highlight unusual expense patterns before they significantly impact returns – an early warning system that helps preserve profitability.
- They enable accurate financial planning: With reliable historical data properly categorised, forecasting accuracy increases. This helps clients plan for expenses, time acquisitions, and manage cash flow more effectively.
- They transform client advisory discussions: With digital record-keeping processes dialled in, client meetings can focus on strategic tax planning and portfolio optimisation rather than sorting out books.
- They strengthen financing positions: Comprehensive digital records typically improve lending outcomes. Clear documentation of property performance often results in better financing terms.
To unlock these valuable business benefits, landlords need more than generic bookkeeping tools. The right software combines property-specific features with robust accounting features.
With MTD requirements on the horizon, most affected landlords will be required to adopt MTD-compatible software, making this the perfect opportunity to implement systems that deliver both compliance and competitive advantage.
Introducing Landlord Studio: Software Built for Property Investors
With MTD deadlines approaching, the software landlords choose matters more than ever. Not every solution delivers what property investors actually need.
The best MTD-compliant software for landlords should include:
- Property-specific tracking to monitor performance across multiple assets
- Automatic bank feeds to reduce manual data entry and errors
- Digital receipt capture that meets HMRC requirements
- Clear, actionable reporting that highlights opportunities and issues
- Seamless sharing with accountants to facilitate ongoing advice
Landlord Studio ticks all these boxes, offering tenant management, property-specific expense categories, and rental income tracking functions that generic accounting software typically lacks.
Its integration with Xero and other accounting tools creates a complete, connected system that meets MTD requirements while assisting both accountants and landlords simultaneously.
Helping Landlords Make the Switch to Digital
The transition to MTD won’t happen overnight. Most landlords have record-keeping habits they’ve used for years, and changing them will take time and support.
Focus on practical benefits rather than just compliance. When clients can observe how digital systems solve everyday frustrations like finding receipts or categorising expenses correctly, they’re more motivated to change. Using intuitive, landlord-specific software is crucial to delivering those benefits.
When it comes to implementation, starting with a single property helps build replicable processes that scale. Ahead of the deadline, provide extra support, as HMRC doesn’t look like they’ll be extending much tolerance for mistakes after roll-out.
On the positive side, many landlords will discover how much time they save once digital systems are in place. Those hours previously spent on paperwork can be channelled towards more valuable activities, whether improving their properties or growing portfolios.
Wrapping Up
HMRC has partly designed the MTD systems to improve compliance, saving them time in trawling through a vast amount of annual self–assessment data. Meanwhile, ongoing record-keeping responsibilities are placed squarely on the taxpayer’s shoulders.
Landlord Studio offers the kind of tools investors need to master this transition – specialised features built for rental properties that satisfy MTD requirements while delivering everyday benefits. The platform’s direct integration with Xero ensures your practice and your clients stay perfectly in sync.
