Who Benefits from Automatic Profit Splits?

Whether you own property with a spouse, business partner or family member, RentalBux simplifies your tax reporting and compliance.

Married Couples and Civil Partners

You and your partner own rental property jointly. HMRC allows you to elect for unequal profit shares if you own the property as tenants in common. RentalBux automatically calculates and reports each partner's share, ensuring your MTD submissions reflect the correct ownership percentages.
