From 6 April 2026, MTD record keeping for landlords becomes mandatory for anyone with gross rental income over £10,000. This means switching from paper-based systems to digital records that can be submitted quarterly through compatible software.

The change affects most UK landlords, but many are unclear about exactly what records they need to keep digitally. Getting this wrong could result in penalties, so understanding the requirements is crucial for compliance.

What Is MTD Record Keeping for Landlords?

Making Tax Digital (MTD) for Income Tax requires landlords to keep digital records of their rental business and submit quarterly updates to HMRC. Unlike the current annual Self Assessment system, you'll need to report income and expenses four times per year.

The key change is that all records must be stored digitally in MTD-compatible software. You can't simply scan paper receipts and call them "digital" – the records must be created and maintained in approved software from the start.

For detailed information about MTD deadlines and who's affected, see our complete MTD guide for landlords.

Which Landlords Need Digital Records?

MTD record keeping requirements apply to landlords with:

  • Gross rental income over £10,000 per year from UK property
  • Multiple properties where combined gross income exceeds £10,000
  • Joint ownership where your share of gross income is over £10,000
  • Commercial property rentals (no exemption threshold)

Gross income means total rent received before deducting expenses like mortgage interest, repairs, or letting agent fees. Even if your net profit is minimal due to high expenses, you're still caught by MTD if gross income exceeds £10,000.

Exemptions from Digital Records

You're exempt from MTD record keeping if:

  • Gross rental income is £10,000 or less per year
  • You only receive income from Rent-a-Room scheme (up to £7,500 tax-free)
  • You're a non-resident landlord (separate MTD timeline applies)

Essential Digital Records Landlords Must Store

Under MTD rules, landlords must maintain digital records covering all aspects of their rental business. These fall into several categories:

Income Records

Every penny of rental income must be recorded digitally:

  • Monthly rent payments – date, amount, property address, tenant name
  • Deposit retentions – amounts kept for damage or unpaid rent
  • Service charge recoveries – utilities, maintenance, communal costs recovered from tenants
  • Letting agent statements – showing rent collected and deductions
  • Insurance claim payouts – for property damage or loss of rent
  • Subletting income – if tenants sublet with permission

The records must show the date income was received (or due), not when it was earned. This follows the cash accounting method that most landlords use.

Expense Records

All allowable property expenses need digital documentation:

  • Mortgage interest – monthly statements showing interest portions
  • Repairs and maintenance – invoices for fixing existing problems
  • Professional fees – letting agent, property management, legal, and accountant costs
  • Insurance premiums – landlord and building insurance
  • Council tax and utilities – when paid by landlord
  • Safety certificates – gas safety, electrical testing, EPC costs
  • Marketing costs – property advertising, tenant finding fees

Remember that mortgage interest relief is restricted under Section 24 rules, providing only a 20% tax credit rather than full deduction.

Capital Expenditure Records

While not deductible against rental income, capital expenses must be tracked for Capital Gains Tax purposes:

  • Property purchase costs – legal fees, stamp duty, survey costs
  • Improvement works – extensions, conversions, substantial renovations
  • Capital items – new boilers, kitchens, bathrooms (improvements, not repairs)
  • Disposal costs – estate agent fees, legal costs when selling

MTD Receipts Requirements: What Documentation Do You Need?

The MTD receipts requirements go beyond simply recording transactions. You need supporting documentation for every entry:

Acceptable Digital Receipts

  • PDF invoices and receipts – emailed or downloaded from supplier websites
  • Bank statement downloads – showing payment dates and amounts
  • Letting agent statements – monthly or quarterly summaries
  • Online banking screenshots – properly saved as files, not just viewed
  • Supplier account portals – utility bills, insurance documents accessed online

Converting Paper to Digital

If you receive paper receipts, they must be converted to digital format immediately:

  • High-quality scans or photos – clear, readable images showing all details
  • Proper file naming – date, supplier, amount for easy identification
  • Secure storage – cloud backup or multiple device copies
  • Original disposal – you can destroy paper once digitally stored (but many keep them)

How Long Must You Keep Digital Records?

Under MTD rules, digital records landlords must retain all documentation for at least 5 years after the submission deadline. This is longer than the current 22 months for Self Assessment records.

The 5-year period starts from 31 January following the end of the tax year. For 2026/27 records, you'd need to keep them until at least 31 January 2033.

Best Practice Record Retention

Many property accountants recommend keeping records longer than the minimum requirement:

  • Capital gains records – keep until 6 years after property disposal
  • Dispute protection – HMRC can investigate further back in cases of suspected errors
  • Mortgage applications – lenders often want 3+ years of accounts
  • Insurance claims – some policies require historical documentation

MTD-Compatible Software for Record Keeping

Your digital records must be maintained in software that can connect to HMRC's systems. Free options include:

  • HMRC's own software – basic but sufficient for simple portfolios
  • Spreadsheet bridges – connect Excel to HMRC (limited functionality)
  • Free accounting software – basic versions of commercial products

Paid software typically offers better features for landlords with multiple properties, automatic bank feeds, and integration with letting agents.

Key Software Features for Landlords

  • Property-by-property tracking – separate income and expenses
  • Receipt storage – attach digital documents to transactions
  • Bank integration – automatic transaction import
  • Quarterly reporting – generate MTD submissions
  • Capital gains tracking – maintain CGT records

Common Digital Record Keeping Mistakes

These errors could trigger HMRC penalties under MTD:

Incomplete Income Records

Many landlords focus on expenses but miss income items:

  • Failing to record deposit retentions as income
  • Missing service charge recoveries from tenants
  • Not including insurance payouts for loss of rent
  • Overlooking rent paid direct by housing benefit

Mixed Business and Personal Expenses

Using personal accounts for property expenses creates problems:

  • Difficulty separating business and personal transactions
  • Missing expenses paid from personal funds
  • Inadequate documentation for mixed-use items

Poor Receipt Management

  • Low-quality scans that become unreadable
  • Inconsistent file naming making documents hard to find
  • No backup systems risking data loss
  • Failing to link receipts to accounting entries

Setting Up Your Digital Record System

Start preparing for MTD now, even if your rental income is currently below £10,000:

Step 1: Choose Your Software

Research MTD-compatible options and test free trials. Consider your portfolio size, complexity, and budget. Many landlords benefit from professional guidance when selecting systems.

Step 2: Separate Business Banking

Open dedicated accounts for rental income and expenses. This simplifies record keeping and makes bank feed integration more effective.

Step 3: Create Filing Systems

Establish consistent folder structures and naming conventions:

  • Property folders – separate section for each rental
  • Date-based filing – YYYY-MM-DD format for chronological order
  • Expense categories – match your accounting software structure
  • Backup procedures – cloud storage with local copies

Step 4: Start Digital-First

Begin requesting electronic invoices and statements from suppliers. Set up online accounts with utility companies, insurance providers, and other regular services.

Professional Support for MTD Compliance

Many landlords find MTD record keeping challenging, especially those with multiple properties or complex arrangements. Professional help can ensure compliance and often saves time in the long run.

A specialist property accountant can help with:

  • Software selection and setup
  • Record keeping system design
  • Quarterly MTD submissions
  • Ongoing compliance monitoring
  • Integration with existing processes

The cost of professional support is often offset by the time saved and peace of mind from knowing your records meet HMRC requirements.

Preparing for April 2026

With MTD mandatory from April 2026, start your preparation now:

  • Audit current systems – identify gaps in your record keeping
  • Test software options – don't wait until the deadline
  • Train yourself or staff – new systems require learning time
  • Review processes – streamline data capture and filing
  • Consider professional help – especially for complex portfolios

Remember that MTD affects more than just record keeping. You'll also need to understand quarterly reporting requirements, cash basis accounting rules, and how MTD interacts with existing tax reliefs.
