RentalBux finally gave me peace of mind.


Even after trying several tools, I was struggling with my portfolio of three rentals. MTD just added to that struggle. But then, I was introduced and all my worries disappeared. MTD submissions in minutes, track each property separately, allocate profit sharing. Wow!

As a landlord managing 12 units across two ownership structures and some self-employment income, I needed something that handled everything. RentalBux was the only software that did that.

Time saved.


Switching to RentalBux was one of the best decisions I made. Especially the joint-ownership module. Our family property had three owners with different shares, and RentalBux handled it quite efficiently.

Real challenges jointly owned property landlords face, and how RentalBux solves them

Challenges Jointly Owned Property Landlords face How RentalBux Solves It
Residential rental income from multiple properties and tenants, sometimes missed or delayed. RentalBux tracks all rent receipts in one dashboard, automatically reconciling payments for accurate MTD reporting.
Property-related expenses such as repairs, maintenance, and utilities are scattered or lost. Snap receipts or upload invoices; RentalBux auto-categorises them according to HMRC rules.
Mortgage interest, insurance, and professional fees are complicated to record for deductions. RentalBux maps each expense correctly, ensuring all allowable deductions are captured.
Keeping separate records for multiple properties is time-consuming. RentalBux allows separate property accounts while combining totals for MTD threshold compliance.
Confusion over quarterly submissions and year-end final declaration. Built-in reminders, guided workflows, and HMRC-recognised filing simplify MTD compliance and reduce stress.

FAQ Section Image
If you’re a residential landlord and your annual rental income for Tax Year 2024/25 exceeds £50,000, Making Tax Digital (MTD) for residential landlords applies from 6 April 2026.
MTD requires landlords to keep digital records of all rental income and allowable property expenses, submit quarterly updates to HMRC, and complete a year-end final declaration.
Some residential landlords may be eligible for digital exemptions. HMRC allows exemptions based on:
  • Age or health conditions that make digital record-keeping impossible
  • Religious beliefs that prevent using computers or digital platforms
  • Location issues (e.g., limited internet access)
Landlords meeting these exemption criteria can apply to HMRC to avoid MTD compliance, but most UK residential landlords whose gross qualifying income exceeds the threshold need to comply with digital tax reporting requirements.
Yes. RentalBux provides a free version for landlords managing a single property unit. For landlords with growing rental portfolios, RentalBux also offers upgrade options with extended features, allowing you to manage multiple properties, track additional expenses, and handle complex MTD requirements efficiently. This ensures landlords can scale their bookkeeping and MTD compliance as their property business grows.
All landlords whose total gross rental income from all rental properties exceeds the MTD threshold (£50,000 for Tax Year 2024/25) will need to comply. This includes residential landlords, HMOs, furnished holiday lets, buy-to-let properties, and mixed-use properties. MTD for residential landlords applies to all these types of rental income.
The MTD income threshold is based on total rental income across all properties, not per property. Even if you manage multiple smaller rental units, HMRC calculates your gross qualifying income as the sum of all rental income streams for the year. To check the threshold and the MTD for residential landlords mandating year for your residential property rentals read Self-Assessment tax return.
