If you co-own one or more rental properties and your individual share of annual rental income from jointly owned properties for Tax Year 2024/25 exceeds £50,000, MTD for jointly owned property landlords applies from 6 April 2026.
MTD requires joint owners to keep digital records of their share of all rental income and allowable property expenses, submit quarterly updates to HMRC, and complete a year-end final declaration.
RentalBux allows joint owners to record the full property-level income and expenses, then automatically calculate and report each co-owner’s share according to ownership percentages. Only your portion of rental income and allowable expenses is submitted in your quarterly updates and year-end declaration, ensuring HMRC compliance.
Yes. RentalBux provides a free version for landlords managing a single jointly owned property. For co-owners with multiple properties or units, RentalBux offers upgrade options with extended features, allowing you to manage your share of income, expenses, and quarterly updates efficiently. This ensures accurate MTD for jointly owned property landlords compliance for each co-owner.
Allowable expenses include property-related costs that can be claimed for tax purposes, such as repairs, maintenance, insurance, mortgage interest, professional fees, utilities, and service charges. RentalBux calculates your share of each expense automatically based on ownership percentage so that only the relevant portion is reported in your MTD submissions.

MTD obligations apply individually. If one co-owner qualifies for a digital exemption (e.g., due to age, health, or location), they can apply to HMRC to be exempt. The co-owner who does not qualify must still keep digital records and submit quarterly updates and a year-end final declaration for their share of the income and expenses under MTD for jointly owned property landlords.
Yes. HMRC allows two key relaxations for joint property owners:
Income reporting flexibility: Co-owners can report gross rental income from jointly held properties in their quarterly updates while deferring the reporting of expenses until the year-end final declaration.
Simplified digital records: Joint owners can create a single digital record for each category of income and a single digital record for each category of expense, removing the need for individual transaction-level records.
