Why Landlords Rely On Us
Trusted by thousands of commercial landlords across the UK
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!
Built for landlords, used by landlords.
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.

Feel the Difference RentalBux Makes
Real challenges commercial landlords face, and how RentalBux solves them
| Challenges Commercial landlords face | How RentalBux Solves It |
|---|---|
| Rent, service charge recoveries, and business rates contributions are received from multiple tenants across different units, difficult to track and reconcile manually. | A single dashboard tracks rent, deposits, service charges, and void-period business rates. RentalBux automatically reconciles payments and flags outstanding balances for accurate MTD digital records. |
| Commercial property expenses (repairs, insurance, management fees, maintenance, utilities) are scattered in emails, PDFs, and folders making deductions difficult to claim at year-end. | Snap receipts or upload invoices; RentalBux auto-categorises expenses to HMRC-approved categories, helping maximise allowable deductions and reduce missed claims. |
| Running multiple commercial units, mixed-use premises, or multiple tenants under one property makes bookkeeping overwhelming. | RentalBux allows separate ledgers for each unit or property, while automatically aggregating totals for MTD threshold calculations and quarterly submissions. |
| Quarterly updates, digital record-keeping rules, and the final declaration under MTD can be confusing and time-consuming. | Guided workflows, automatic reminders, and HMRC-recognised MTD submissions take the pressure off, no tax or software expertise required. |
Frequently Asked Questions
Find answers to common questions about our services and solutions.
If you’re a commercial landlord and your annual rental income for Tax Year 2024/25 exceeds £50,000, MTD for commercial 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 commercial 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 commercial 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 software for commercial landlords compliance as their property business grows. The MTD income threshold for commercial landlords is based on total rental income across all commercial properties you own, not per individual property. Even if you manage multiple units, mixed-use buildings, or office spaces, HMRC calculates your gross qualifying income as the sum of all rental income streams for the year. This ensures that landlords with several smaller or larger commercial properties are assessed correctly for MTD for commercial landlords compliance.

No. MTD for Income Tax applies to individual landlords.
Companies continue filing accounts and corporation tax returns as usual and will later enter MTD for Corporation Tax when HMRC rolls it out (no confirmed date yet).
No. After the tax year ends, commercial landlords submit a Year-End Final Declaration under Making Tax Digital. It replaces the current Self-Assessment return by covering both mandated incomes, such as rental property earnings & self-employment incomes, and non-mandated income, such as dividends, savings, etc., processed through MTD software for commercial landlords
