From 6 April 2026, UK landlords with gross property income over £10,000 must comply with Making Tax Digital (MTD) for Income Tax. This means submitting quarterly updates to HMRC using MTD-compatible software. The MTD quarterly deadlines 2026 2027 follow a strict schedule that all affected landlords must understand to avoid penalties.

Unlike the current annual self-assessment system, MTD requires four quarterly submissions plus an end-of-period statement. Each quarter has a specific deadline, typically one month and five days after the quarter ends. Missing these dates triggers automatic penalties, making compliance essential for property investors.

MTD Quarterly Periods and Deadlines 2026/27

The tax year 2026/27 runs from 6 April 2026 to 5 April 2027, divided into four quarterly periods. Here are the key MTD submission dates every landlord must know:

  • Q1 (6 April - 5 July 2026): Deadline 5 August 2026
  • Q2 (6 July - 5 October 2026): Deadline 5 November 2026
  • Q3 (6 October 2026 - 5 January 2027): Deadline 5 February 2027
  • Q4 (6 January - 5 April 2027): Deadline 5 May 2027

Each quarterly update must include your rental income and allowable expenses for that specific three-month period. The deadline is always one month and five days after the quarter ends, giving landlords time to gather receipts and update their records.

Remember, these quarterly submissions are in addition to your final annual submission, which remains due by 31 January 2028 for the 2026/27 tax year. This final submission reconciles your quarterly updates and calculates your final tax liability.

What Information Must Be Included in Each Quarterly Update?

Each quarterly MTD submission must include detailed property income and expense data for that specific period. Unlike annual returns where you can estimate and adjust, quarterly updates require accurate, period-specific information.

Income to Report

  • Rental income received during the quarter
  • Service charges collected from tenants
  • Insurance claims received for property damage
  • Rent deposits retained (if applicable)
  • Any other property-related income

Allowable Expenses

You can claim expenses incurred during each quarter, including:

  • Repairs and maintenance costs
  • Letting agent fees for that period
  • Property insurance premiums
  • Utilities if landlord-paid
  • Marketing and advertising costs
  • Professional fees (legal, surveyor, accountant)

For landlords affected by Section 24 restrictions, mortgage interest must still be reported quarterly, even though relief is limited to the basic rate tax credit.

MTD Software Requirements for Quarterly Submissions

HMRC requires all quarterly updates to be submitted through MTD-compatible software. You cannot use paper forms or HMRC's basic online services for these submissions. The software must be able to:

  • Connect directly to HMRC's MTD APIs
  • Store digital records of all income and expenses
  • Calculate quarterly profit/loss automatically
  • Submit updates electronically to HMRC
  • Maintain an audit trail of all submissions

Popular MTD software options include QuickBooks, Xero, FreeAgent, and Sage. Many are specifically designed for landlords and can handle multiple properties, tenant management, and allowable expense categories.

The software typically costs £10-30 per month, though some providers offer free versions for simple property portfolios. Factor this ongoing cost into your property investment budgets from April 2026 onwards.

Penalties for Missing MTD Quarterly Deadlines

HMRC operates a strict penalty regime for late MTD submissions. Unlike self-assessment where you might receive warnings, MTD penalties are automatic and escalate quickly.

Late Submission Penalties

  • 1 day late: £100 fixed penalty
  • 3 months late: Additional £300
  • 6 months late: Additional £300
  • 12 months late: Additional penalty up to £300 or 5% of tax due

These penalties apply to each late quarterly update. If you miss all four quarters, you could face £1,600 in penalties before any tax calculation. For landlords with multiple properties, the financial impact can be significant.

There are limited reasonable excuse provisions, typically covering serious illness, technology failures, or postal delays. HMRC's interpretation of "reasonable excuse" is generally strict, so maintaining good records and systems is essential.

Who Must Follow MTD Quarterly Deadlines?

MTD for Income Tax applies to landlords whose total gross property income exceeds £10,000 in the tax year. This threshold includes:

  • Rental income from all UK properties
  • Furnished holiday lettings income (despite regime abolition)
  • Commercial property rentals
  • Room rentals and lodger income
  • Service charges and other property-related income

The £10,000 threshold is based on gross income, not profit. A landlord with £12,000 annual rental income but £8,000 expenses still falls within MTD requirements. For detailed MTD eligibility rules, consider your total property income across all sources.

Exemptions and Special Cases

Certain landlords remain outside MTD requirements:

  • Properties held in limited companies (different MTD rules may apply later)
  • Landlords with gross property income under £10,000
  • Trustees managing property on behalf of beneficiaries
  • Some partnership structures (complex rules apply)

For landlords considering incorporation to a limited company, MTD compliance is one factor to consider alongside Section 24 restrictions and other tax implications.

End-of-Period Statement: The Fifth Submission

Beyond the four quarterly updates, landlords must submit an end-of-period statement by 31 January following the tax year end. For 2026/27, this means a final submission by 31 January 2028.

This statement reconciles your four quarterly submissions with your final annual position. It includes:

  • Confirmation of total annual income and expenses
  • Any adjustments to quarterly figures
  • Claims for annual reliefs and allowances
  • Capital allowances calculations
  • Final tax calculation and payment due

The end-of-period statement is when many traditional tax planning strategies apply, such as timing capital expenditure or claiming overlap relief from previous years.

Record-Keeping Requirements Under MTD

MTD imposes strict digital record-keeping requirements. All property income and expense records must be maintained digitally and preserved for at least five years after the submission deadline.

What Records to Keep

  • Rental statements and payment records
  • Bank statements showing property transactions
  • Receipts and invoices for all expenses
  • Mortgage statements and interest calculations
  • Insurance policies and premium payments
  • Letting agent statements and fee breakdowns

Paper records can be scanned and stored digitally, but HMRC expects landlords to move away from manual record-keeping systems. The software you choose should integrate with your bank feeds and receipt management to automate much of this process.

Planning for Your First MTD Year

The transition to quarterly reporting requires advance planning, particularly for landlords currently managing annual compliance. Consider these preparation steps:

Before April 2026

  • Choose and set up MTD-compatible software
  • Digitise existing property records
  • Establish monthly bookkeeping routines
  • Review current accounting processes
  • Consider professional support for setup

Ongoing Compliance

Successful MTD compliance requires regular attention throughout the year. Many landlords find monthly record updates easier than quarterly rushes. Consider setting aside time each month to:

  • Input rental income received
  • Record and categorise expenses
  • Reconcile bank transactions
  • Review software-generated reports
  • Prepare for upcoming submission deadlines

For larger portfolios or complex situations, many landlords engage specialist property accountants to manage MTD compliance while they focus on property management and investment decisions.

Professional Support for MTD Compliance

While MTD software handles the technical submission process, many landlords benefit from professional guidance, particularly during the transition year. Property tax specialists can help with:

  • Software selection and setup
  • Initial record digitisation
  • Quarterly submission preparation
  • Tax planning within MTD constraints
  • Penalty appeals and compliance issues

The cost of professional support varies, but many landlords find the compliance certainty and time savings worthwhile, particularly given the automatic penalty regime.

Consider engaging professional help early in 2026 to ensure smooth MTD implementation rather than waiting for compliance issues to arise.
