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. Many people assume they need separate software or submissions for each income type. The good news? You can report everything together in a single quarterly update - but there are specific rules about how this works.

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 when your total gross income from self-employment and property exceeds £50,000 in the previous tax year. This includes:

• All self-employment income (before expenses)
• All rental income (before expenses)
• 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 profits from any trade or profession
• Rental income from UK 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 the £40,000 (£25,000 + £15,000) counts for MTD. You'd still need quarterly updates because this exceeds £50,000.

How Quarterly Updates Work with Mixed Income

Once you're in MTD, you submit one quarterly update covering all your income sources. You don't need separate submissions for self-employment and rental income.

Each quarterly update includes:

• Total income for each source during the quarter
• Total allowable expenses for each source
• Any other relevant information (like capital allowances)

The Four Quarterly Periods

MTD uses the same four quarters regardless of your income mix:

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

You can't split different income sources across different quarters. Everything must be reported for the same periods.

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
• Both connected to the same MTD submission

You can use the same software for both, or different software that can submit together. 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
• Both in a single quarterly update

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's quarterly updates include:

• Consultancy income and expenses
• Combined rental income from all three properties
• Property expenses (which can be split by property if needed)

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 doesn't need quarterly updates yet.

If Lisa's business grows and her combined self-employment and rental income exceeds £50,000, she'll need to start MTD quarterly updates.

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 both in one quarterly update
• 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

Quarterly updates don't replace your annual tax return. After submitting four quarterly updates, you still need to complete an End of Period Statement and final declaration by 31 January following the tax year.

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.

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.
