Joint Rental Income Under MTD: How HMRC Expects You to Split and Report Earnings 

If you jointly own a rental property, you may already be splitting the income and declaring it each year. On the surface, it seems straightforward. 

However, with the introduction of Making Tax Digital, the way rental income is recorded and reported has changed in a way that many landlords are still adjusting to. 

Under Making Tax Digital for Income Tax Self Assessment (MTD for ITSA), you are no longer submitting one combined annual figure. Instead, each owner must: 

• Keep their own digital records  

• Report their share of income separately  

• Submit updates to HM Revenue and Customs throughout the year  

This means HMRC now receives multiple submissions linked to the same property, making it easier to identify inconsistencies between joint owners. 

In practice, this is where many issues arise and small mistakes can quickly lead to compliance problems if not handled correctly. 

Quick Answer  

• Each owner reports their own share of rental income, not the total  

• Income must follow beneficial ownership  

• Expenses must be split in the same ratio as income  

• Each owner submits separate quarterly updates  

• Inconsistent reporting can trigger HMRC checks  

The Core Rule: Tax Follows Ownership, Not Convenience 

The most important principle is simple: 

You are taxed on your share of the property, not on who receives the rent or manages the property. 

This applies across: 

• Making Tax Digital for landlords  

• Making Tax Digital for Income Tax  

• Making Tax Digital for Income Tax Self Assessment  

If this rule is misunderstood, it is one of the main reasons joint landlords face reporting issues. 

How Rental Income Should Be Split 

Married Couples or Civil Partners 

• Default split is 50:50  

• To declare a different split, you must submit Form 17  

• Supporting evidence is required  

Other Joint Owners 

Income is split based on: 

• Ownership percentage  

• Legal agreements  

• Financial contribution  

Each owner must report only their share. 

Real Scenarios Where Landlords Get It Wrong 

Scenario 1: One Person Receives All the Rent 

Even if rent is paid into one account, each owner must still report their share. 

Scenario 2: Ownership and Income Do Not Match 

If ownership is 60:40, income must follow that split unless formally declared otherwise. 

Scenario 3: Expenses Claimed by One Owner 

Expenses must be divided in the same ratio as income, not claimed by one person alone. 

Scenario 4: Different Figures Submitted 

If joint owners submit different figures, HM Revenue and Customs may identify inconsistencies. 

What Has Changed Under Making Tax Digital 

Before MTD: 

• One annual return  

• Limited visibility of discrepancies  

Under MTD: 

• Quarterly reporting  

• Digital records  

• Greater transparency for HMRC  

This makes accurate and consistent reporting far more important. 

Step by Step: How to Stay Compliant 

To meet Making Tax Digital for Income Tax Self Assessment requirements: 

1. Confirm your ownership split  

2. Record income based on that split  

3. Allocate expenses in the same ratio  

4. Keep separate digital records  

5. Use reliable Making Tax Digital software  

6. Ensure both owners submit consistent figures  

Practical Example 

Property ownership: 

• Owner A: 60%  

• Owner B: 40%  

Monthly rent: £1,000 

Reporting: 

• Owner A: £600  

• Owner B: £400  

Expenses (£200): 

• Owner A: £120  

• Owner B: £80  

Each owner submits their figures separately. 

Where HMRC Is Most Likely to Challenge 

According to HM Revenue and Customs, issues are more likely where: 

• One owner reports all income  

• Ownership percentages are inconsistent  

• Expenses do not match income ratios  

• Joint owners submit different figures  

These checks are based on data consistency rather than random selection. 

Why Proper Structuring Matters 

Joint rental income becomes more complex when: 

• Ownership is unequal  

• Contributions differ  

• One person manages finances  

In these cases, applying HMRC rules correctly requires a structured approach. 

At Brayan & Spencer Associates, the focus is on helping landlords: 

• Align ownership with reporting  

• Maintain accurate digital records  

• Ensure consistency across submissions  

This reduces the risk of errors under Making Tax Digital.

Conclusion: Getting Joint Rental Income Right Under MTD 

Joint rental income has always required careful handling, but under Making Tax Digital, the margin for error is much smaller. 

The key challenge is no longer just understanding the rules — it is applying them consistently across separate digital submissions. Because each owner now reports individually, even small differences in income, expenses, or ownership percentages can create inconsistencies that are visible to HM Revenue and Customs. 

In practical terms, most issues arise when: 

• Income is reported by one owner instead of being split  

• Ownership and income percentages do not match  

• Expenses are not allocated correctly  

• Records between owners are not aligned  

A clear and consistent approach is essential: 

• Confirm how the property is owned  

• Apply that split consistently  

• Keep accurate digital records  

• Ensure all submissions match  

As Making Tax Digital for Income Tax Self Assessment continues to reshape reporting, landlords who structure their records properly from the outset are far better placed to remain compliant and avoid unnecessary complications.
