Rules for mixed MTD status owners
Joint owners of rental properties are not treated as a single entity or business partnership under Making Tax Digital (MTD) rules. Instead, HMRC assesses each co-owner's MTD mandation status individually. This can lead to a "mixed status" scenario where one joint owner is legally required to join MTD ITSA, while the other joint owner remains on the traditional annual Self Assessment filing system.
How Mixed Status Works in Practice
Because thresholds are assessed individually, the income streams of one joint owner do not affect or mandate the other. Each owner is tested based on their personal share of the gross rental income, plus any other personal sole trader business turnover they might have.
Example Scenario: Owner A and Owner B jointly own a rental property that generates £40,000 in gross annual rent. They split the income 50/50, so each has a £20,000 rental income stream.
- Owner A also runs a separate sole trader consulting business with a gross annual turnover of £35,000. When testing for Phase 1, Owner A's total qualifying income is £55,000 (£35,000 sole trade + £20,000 rental share). Since this is over £50,000, **Owner A must register for MTD ITSA** and submit digital records and quarterly updates for both their sole trade and their share of the property.
- Owner B has no other self-employment income (their only other income is a PAYE employment salary, which is excluded from qualifying income). Owner B's total qualifying income is simply their £20,000 rental share. Since this is below £50,000 (and even below £30,000), **Owner B remains on the traditional Self Assessment route** and does not need to submit quarterly updates.
Handling Letting Agent Statements
Mixed status poses unique challenges for record-keeping, especially when a property is managed by a third-party letting agent. Letting agents typically issue a single consolidated monthly statement showing net rents (after deducting the agent's fees, maintenance, and management commissions).
Net agent statements — two different rules
HMRC's testing rules allow you to use a net share figure from your letting agent statement when calculating your threshold. However, once you are mandated into MTD, you cannot rely on net figures for digital record-keeping. You must obtain gross rent figures and record the expenses (such as letting agent fees) as separate transactions in your compatible software.
Furthermore, because Owner A is on MTD and Owner B is not, Owner A must ensure their bookkeeping software is updated at least quarterly with their 50% share of gross transactions, whereas Owner B only needs to compile their 50% share once a year for their annual return. This highlights the importance of maintaining digital records that can easily split transactions by percentage.
