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 commercial landlords face, and how RentalBux solves them

Challenges commercial landlords face How RentalBux solves it
Rent, service charge recoveries, and business rates contributions arrive from multiple tenants and units—tracking and reconciling manually is painful. A single dashboard tracks rent, deposits, service charges, and void-period business rates, auto-reconciling receipts and flagging arrears for accurate MTD records.
Commercial property expenses (repairs, insurance, management fees, maintenance, utilities) sit in emails, PDFs, and folders, making deductions hard at year-end. Snap receipts or upload invoices once; RentalBux auto-categorises spend into HMRC categories so allowable deductions aren’t missed.
Managing multiple commercial units, mixed-use premises, or many tenants under one property overwhelms bookkeeping. Keep separate ledgers per unit or property while RentalBux automatically aggregates totals for MTD thresholds and quarterly submissions.
Quarterly updates, digital record keeping, and the final declaration under MTD feel confusing and time-consuming. Guided workflows, automatic reminders, and HMRC-recognised submissions take the compliance pressure off—no tax or software expertise needed.

FAQ Section Image
If you’re a commercial landlord and your annual rental income for Tax Year 2024/25 exceeds £50,000, Making Tax Digital (MTD) 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 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 compliance. To check the threshold and the MTD mandating year for your commercial property rentals read our article.
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.
