Shared property. Manual splits.
Double the work. There’s a better way.
Own rental property with your spouse, partner, or business associate? Stop managing two separate accounts. RentalBux automatically splits rental income, expenses, and MTD submissions based on your ownership percentages-whether 50:50, 45:35:30, or any custom arrangement.
Set Up Joint Ownership in Minutes
Allocate properties, assign ownership percentages, and automate your reporting all in one place.
Under Making Tax Digital (MTD), each co-owner must report their individual share of rental income and expenses to HMRC quarterly. RentalBux handles this automatically set up once, and every transaction, report, and submission is split correctly.

Who Benefits from Automatic Splits?
Joint Ownership Made Simple
You and your spouse/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.
Multi-Owner Property Management
You own multiple properties with a business associate on a 60/40 or 70/30 basis. Instead of maintaining two separate accounting systems, RentalBux automatically splits all income and expenses, giving each partner a clear, accurate record for their tax return.
Keep It in the Family
You have invested in property with a parent, sibling, or adult child. Each co-owner needs their own MTD submission, but managing this manually is time-consuming and error-prone. RentalBux handles the split for you reducing admin and ensuring compliance.

Get Started FreeFrequently Asked Questions
Find answers to common questions about our product, services, and policies
Can I add more than one landlord?
Yes, you can add as many landlords as you need! Our platform supports unlimited joint ownership arrangements, making it easy to manage properties with multiple owners.
Do I need to tell each landlord's split?
Yes, you'll need to specify the percentage split for each landlord to ensure accurate income distribution and tax reporting. This helps us calculate each owner's share of rental income and expenses correctly.
Can the split be unequal?
You can set any percentage split that reflects your ownership agreement. For example, one owner could have 70% and another 30%, or any other combination that adds up to 100%.
Can the split be changed later on?
Yes, you can update ownership percentages at any time. This is useful when ownership arrangements change, and the system will apply the new split going forward while maintaining historical accuracy.
