What's Covered
UK Residential Properties
Add any number of UK residential properties. Configure ownership type, units, tenancy records and rent due date reminders per property.
Overseas & Foreign Properties
HMRC treats foreign rental income separately from UK income. RentalBux handles this automatically — generating separate income stream data for your MTD submission.
Joint Ownership with Profit Splits
Set your ownership percentage per property. RentalBux automatically calculates your share of all income and expenses and generates your individual MTD submission.
Commercial Properties
Add commercial properties alongside residential. Income and expenses are tracked separately for each property for clearer financial management.
Portfolio-Level Consolidation
View total income and expenses across your entire portfolio, with drill-down to individual property level for any report or export.
Tenancy Record Management
Attach tenancy records to each property with start and end dates, tenant details and rent due day. Link invoices to tenancies for clean income tracking.
Why your property configuration drives your MTD accuracy?
Every MTD quarterly update HMRC receives from you is built from your property-level financial records. If a property is misconfigured, such as an incorrect ownership percentage or misclassified rental income, your quarterly submission will reflect that error.
Getting your property setup right before you start recording transactions is the single most important step in ensuring MTD compliance. RentalBux's property setup guide walks you through every field with clear, plain-English explanations.
Configuration tips
Set ownership percentage first — changing it after transactions requires adjustments
Mark overseas properties as "Foreign" — HMRC requires separate reporting streams
Add tenancy records before creating rent invoices for clean attribution
Use property tags to group properties for consolidated reporting
Joint ownership — how it works in RentalBux
When you co-own a property with a spouse, family member or business partner, you add the property to RentalBux and set your ownership percentage. RentalBux automatically calculates your share of all income and expense transactions, and generates your individual MTD quarterly update showing only your portion. Your co-owner sets up their own RentalBux account and adds the same property with their percentage. Both of you link to the same property records, and RentalBux handles the split automatically.
Overseas properties — HMRC's separate treatment
HMRC treats UK and foreign rental income as two separate income streams, each with its own rules for allowable expenses, loss ring-fencing, and MTD reporting. RentalBux supports both. When you add an overseas property, it's automatically tagged as foreign income and reported in the correct section of your quarterly MTD update — separate from your UK rental income figures.
Frequently asked Questions
How many properties can I add on the free plan?
The free plan supports one property unit with full MTD compliance. For multiple-property units, the Landlord plan starts at three units, with pricing that scales from £4.50/month as you add more units.
Can I add a property I've already sold?
You can mark the properties as sold in RentalBux. Sold properties retain all historical income, expense and tenancy records, which remain accessible and exportable. The property no longer appears in your active portfolio or current MTD calculations.
How do I set up an HMO with multiple rooms?
When adding an HMO, add individual rooms as units within the property. Each unit gets its own tenancy record and rent due date. Income and expenses can be tracked at room level or pooled at property level depending on your preference.
Can RentalBux handle a property owned by a limited company?
Yes. Limited company landlords can use RentalBux for property management and bookkeeping. The Limited Company plan includes a corporation tax workspace. Note: limited companies are exempt from MTD for Income Tax — MTD applies to individuals and partnerships only.
