Multiple Income Sources and MTD: Self-Employed and Landlord Together

If you're both self-employed and a landlord, you're not alone in feeling confused about Making Tax Digital quarterly updates. The key points: your income sources are added together for the threshold, each source then gets its own quarterly update, and one piece of software can handle both.

This guide explains exactly how MTD handles multiple income sources, when you need to start filing, and how to manage both streams without doubling your workload.

The £50,000 Threshold: How It Works with Multiple Income Sources

MTD for Income Tax applies from April 2026 when your total gross income from self-employment and property exceeded £50,000 in 2024-25. This includes:

• All self-employment income (before expenses)
• All rental income, UK and foreign (before expenses, and only your share if jointly owned)
• Income from multiple properties
• Income from multiple trades or businesses

Let's say you earned £35,000 from freelance work and £20,000 from rental income in 2024-25. Your total gross income is £55,000, so you'll need to file MTD quarterly updates from 6 April 2026.

HMRC counts all qualifying income together. You can't avoid MTD by keeping income sources below £50,000 individually if they exceed it combined.

What Income Counts?

For MTD purposes, qualifying income includes:

• Sole trader turnover (before expenses) from any trade or profession
• Rental income from UK and foreign properties
• Income from multiple unrelated businesses

Employment income (PAYE) doesn't count towards the £50,000 threshold. So if you earn £40,000 as an employee, £25,000 from freelancing, and £15,000 from rentals, only £40,000 (£25,000 + £15,000) counts for MTD. That's under £50,000, so you wouldn't be in MTD in April 2026, but you would be from April 2027 if your 2025-26 figures are similar, because it's over £30,000.

How Quarterly Updates Work with Mixed Income

Once you're in MTD, you submit a separate quarterly update for each income source: one for your self-employment and one for your UK property income (and another for foreign property, if you have it). Your software can send them together, but they are separate submissions with the same deadline.

Each quarterly update includes:

• Total income for that source during the quarter
• Allowable expenses for that source, by HMRC category
• For property, residential finance costs such as mortgage interest

Capital allowances and other annual adjustments are not part of quarterly updates. You add them once a year before the final declaration.

The Four Quarterly Periods

These are the standard quarters (you can choose calendar quarters, 1 April to 30 June and so on, instead). The deadlines are the same either way:

1. Q1: 6 April to 5 July (deadline: 7 August)
2. Q2: 6 July to 5 October (deadline: 7 November)
3. Q3: 6 October to 5 January (deadline: 7 February)
4. Q4: 6 January to 5 April (deadline: 7 May)

All your income sources share the same deadlines.

For detailed information about quarterly deadlines, see our guide to MTD quarterly deadlines for 2026-27.

Record-Keeping Requirements

You need digital records for all income sources. This means:

• Self-employment records in compatible software
• Property income records in compatible software
• Each submitted to HMRC through recognised software

You can use the same software for both, or different products for each source. Most people find it easier to use one solution.

Common Scenarios for Mixed-Income MTD

Scenario 1: Freelancer with Buy-to-Let Property

Sarah is a freelance graphic designer earning £45,000 annually. She also rents out a flat for £8,000 per year. Her total gross income is £53,000, so she needs MTD quarterly updates.

Each quarter, Sarah reports:

• Design income and business expenses
• Rental income and property expenses
• As two quarterly updates (one self-employment, one property) sent by the same deadline

Scenario 2: Consultant with Multiple Properties

Mark runs a consultancy earning £30,000 annually. He owns three rental properties generating £25,000 combined. Total gross income: £55,000.

Mark sends two quarterly updates each quarter:

• A self-employment update: consultancy income and expenses
• A UK property update: combined rental income and expenses from all three properties (UK properties are one income source)

Scenario 3: Part-Time Self-Employment with Rental

Lisa works part-time as an employee (£20,000 PAYE) and runs a small online shop (£15,000). She also rents out her old home (£30,000). Her MTD-qualifying income is £45,000 (£15,000 + £30,000), so she isn't in MTD for April 2026.

But £45,000 is over the £30,000 threshold that applies from April 2027. If her 2025-26 income is similar, she'll need to start MTD quarterly updates from 6 April 2027.

Software Requirements for Multiple Income Types

Your MTD software must handle both self-employment and property income. Most bridging software does this automatically, but it's worth checking before you choose.

What to Look For

Essential features for mixed-income MTD:

• Self-employment income and expense tracking
• Property income and expense tracking
• Ability to submit quarterly updates for both sources and the final declaration
• Clear separation between income types for your records

For guidance on choosing the right software, see our comparison of MTD software by income type.

Bridging Software vs Full Accounting Software

Most people with mixed income don't need complex accounting software. Bridging software handles MTD submissions while you keep records your way.

This works well if you:

• Have straightforward income and expenses
• Don't need complex reporting
• Want to minimize software costs
• Already have a record-keeping system that works

Allowable Expenses for Mixed Income

Each income type has different allowable expenses. You can claim legitimate expenses against the relevant income source.

Self-Employment Expenses

Common allowable business expenses include:

• Office costs and equipment
• Travel and motor expenses
• Marketing and advertising
• Professional fees and subscriptions

Property Expenses

Allowable property expenses include:

• Repairs and maintenance
• Insurance and safety certificates
• Lettings agent fees
• Legal and professional costs

For a complete list of what you can claim, see our guide to allowable expenses for MTD sole traders and landlords.

Annual Declaration Still Required

After your quarterly updates, you complete a final declaration by 31 January following the tax year. It replaces your Self Assessment tax return. (The old End of Period Statement has been dropped.)

This annual process allows you to:

• Make final adjustments to your figures
• Claim additional allowances or reliefs
• Include any income not covered by quarterly updates
• Calculate your final tax liability

For more detail on this process, read our explanation of quarterly updates vs final declaration.

Getting Started with Mixed-Income MTD

If you need to start MTD quarterly updates from April 2026, here's your action plan:

1. Check if you need MTD: Calculate your total gross income for 2024-25
2. Choose your software: Find MTD-compatible software that handles both income types
3. Set up digital records: Ensure all income and expenses are tracked digitally
4. Understand the deadlines: Mark the four quarterly deadlines in your calendar
5. Plan your first submission: Prepare for Q1 covering 6 April to 5 July 2026

For a step-by-step approach to preparation, see our 75-day MTD bookkeeping setup guide.

Managing MTD with multiple income sources isn't as complicated as it first appears. The key is understanding that everything goes into one quarterly update, choosing software that handles both income types, and maintaining good records throughout the year. With the right approach, you can meet all your MTD obligations without doubling your administrative workload.
