Making Tax Digital for Income Tax Property (ITSA) becomes mandatory for eligible UK landlords from 6 April 2026. This represents the biggest change to property tax reporting in decades, requiring quarterly digital submissions instead of annual self assessment returns.
If you're a landlord earning over £10,000 from UK property, this will likely affect you. Here's what you need to know about the April 2026 deadline and how to prepare.
What is Making Tax Digital for Property Income?
Making Tax Digital (MTD) for Income Tax Self Assessment starts on 6 April 2026. It affects all landlords and property investors with gross annual income above £10,000 from property rentals.
Under MTD, you'll submit quarterly updates showing your rental income and allowable expenses. These replace the current system where you report everything once a year through self-assessment.
The key changes include:
- Quarterly digital submissions (due by 5th of the month following each quarter)
- Mandatory use of MTD software for landlords
- Digital links between your records and submissions
- An end-of-period statement replacing much of the traditional tax return
Who Must Follow the MTD Rules?
MTD applies to all UK landlords and property investors earning over £10,000 gross annual rental income. This threshold includes:
- Individual landlords with BTL properties
- Portfolio owners with multiple rental properties
- Property developers with rental income (though development profits have separate rules)
- Those with furnished holiday lettings
The £10,000 threshold is based on gross rental income before expenses. A landlord charging £900 monthly rent (£10,800 annually) must comply, even if their profit after mortgage payments and expenses is much lower.
If you operate through a limited company, different MTD rules for corporation tax may apply. Consider speaking with specialists about incorporation structures if you're planning significant changes before 2026.
MTD Software and Digital Record Keeping Requirements
From April 2026, you must maintain digital records of all property-related income and expenses. Paper records and basic spreadsheets won't meet HMRC's requirements — you need MTD-compatible software.
HMRC requires "functional compatible software" that can:
- Keep digital records of income and expenses
- Provide a digital link to HMRC for submissions
- Calculate tax liabilities automatically
- Generate the required quarterly updates
Popular MTD software for landlords includes established accounting packages and property-specific solutions. Most charge monthly subscription fees ranging from £10-50 depending on features and property numbers.
Key features to look for include:
- Bank feed integration for automatic transaction import
- Property portfolio management for multiple BTL properties
- Expense categorisation aligned with property tax rules
- Tenant and lease management tools
- Capital gains tracking for future disposals
Your digital records must capture:
- Rental income received (including deposits and premiums)
- Property expenses and allowable deductions
- Capital expenditure and improvements
- Any other property-related income
Digital record-keeping requirements go beyond simply using software. Your systems must maintain digital links between original records and HMRC submissions. Practically, this means:
- Bank statements imported directly into your software (not manually typed)
- Receipts stored digitally with links to expense entries
- Rental income recorded from bank feeds or integrated property management systems
- No breaking the digital chain with manual adjustments unless unavoidable
You'll still need to keep supporting documents like receipts and invoices, but your primary record-keeping system must be digital and MTD-compatible. Paper receipts are still acceptable, but you must digitise them (by photo or scanning) and link them to your software records.
Quarterly Reporting Timeline and Deadlines
Under MTD for Income Tax Property, you'll submit four quarterly updates plus an annual submission. The quarterly deadlines are:
- Q1 (April-June): Due by 5 August
- Q2 (July-September): Due by 5 November
- Q3 (October-December): Due by 5 February
- Q4 (January-March): Due by 5 May
Each quarterly update summarises your property income and expenses for that three-month period. You don't need to submit detailed breakdowns — summary figures are sufficient. You don't need to apportion annual costs like insurance — just report what was actually paid in each period.
The annual submission (due by 31 January) includes your final property income calculation, any adjustments, and claims for capital allowances or other reliefs.
Impact on Self-Assessment and Tax Planning
Self-assessment won't disappear entirely, but it will change significantly. Instead of reporting all your property income and expenses on the SA105 form, you'll complete an "end-of-period statement" that:
- Confirms your quarterly submissions were accurate
- Makes any final adjustments or corrections
- Declares other income not covered by quarterly MTD submissions
- Claims any additional reliefs or allowances
This is due by 31 January following the tax year end, the same deadline as current self-assessment returns.
Making Tax Digital will significantly change how you manage property tax affairs. The quarterly reporting cycle means you'll need more frequent engagement with your records and tax position. This could actually benefit tax planning. Regular quarterly reviews make it easier to:
- Track rental yield performance across your portfolio
- Time expense payments for optimal tax relief
- Monitor your position against higher rate tax thresholds
- Plan capital expenditure more strategically
However, the administrative burden will increase, particularly for landlords currently managing everything themselves. Many will need to invest in software or engage professional help.
Penalties and Compliance
HMRC will apply penalties for late or missing MTD submissions. The penalty structure mirrors existing self assessment penalties, starting at £100 for late quarterly updates. Late submissions carry penalties starting at £200 for the first missed deadline, rising to £400 and beyond for repeated failures.
However, HMRC typically shows leniency during the first year of new systems. They've indicated a "soft landing" approach for genuine compliance efforts, though this shouldn't be relied upon.
More concerning are the potential penalties for inadequate digital records. HMRC can impose penalties up to £3,000 for failing to keep proper digital records, though these would likely only apply in serious cases.
Impact on Different Types of Landlords
Individual BTL Landlords
Most straightforward cases — typically quarterly submissions showing rental income and standard expenses like maintenance, insurance, and management fees. Section 24 mortgage interest restrictions continue to apply.
Portfolio Owners
Multiple properties require careful expense allocation and may benefit from more sophisticated software with portfolio management features. Consider whether the increased compliance burden supports arguments for incorporation.
Holiday Let Operators
Furnished holiday lettings have additional complications around occupancy requirements and capital allowances. Ensure your chosen software handles these specific rules correctly.
Preparing for the April 2026 Deadline
Start preparing now, even though the deadline is still over a year away. Successful preparation requires planning across several areas:
Assess Systems and Select Software
Review how you currently track rental income and expenses. If you're using basic spreadsheets or paper records, you'll need to upgrade. Choose and implement your MTD software well before April 2026. Allow time to import historical data, connect bank feeds, and train yourself or your team on the new system.
Review Record Keeping and Processes
Ensure you're capturing all necessary information in a format that will work with digital systems. This includes proper categorisation of income and expenses. Quarterly reporting demands more regular bookkeeping. Instead of gathering receipts once yearly, you'll need organised monthly processes to meet quarterly deadlines.
Consider Professional Support and Cash Flow
If you're managing a substantial portfolio, professional help might be cost-effective. Accountants specialising in property can handle the MTD submissions while you focus on property management. Quarterly submissions may trigger more frequent tax payments on account. Plan cash flow carefully, especially if you currently benefit from the delay between earning rental income and paying tax 15-22 months later.
Common Concerns and Misconceptions
Many landlords worry about the complexity of Making Tax Digital, but several common concerns are overblown:
Myth: You need expensive, complex software.
Reality: Basic MTD-compatible solutions cost £10-20 monthly and handle most landlord requirements.
Myth: Quarterly submissions mean paying tax four times per year.
Reality: Submissions are informational. Tax payments typically remain twice-yearly through the payments on account system.
Myth: Small landlords are exempt.
Reality: The £10,000 threshold is relatively low. Most landlords with even single BTL properties exceed this.
Getting Ready: Next Steps
Start preparing for making Tax Digital for landlords now:
- Calculate your gross annual rental income to confirm MTD applies
- Research and trial MTD-compatible software options
- Review your current record-keeping and identify improvement areas
- Consider professional support if your situation is complex
- Plan the transition timeline to avoid last-minute pressure
The April 2026 deadline will arrive faster than expected. Landlords who prepare early will find the transition smoother and less disruptive to their property business operations.
