Making Tax Digital (MTD) for Accountants - Software Built by Accountants for Accountants.
One platform for landlords, sole traders, and mixed-income clients.
Automatic profit splits, MTD workflows, AI-powered transaction classification and direct HMRC submission. Bulk client management, deadline tracking, and flexible ledger mapping – built around how your firm actually works.
Built by UK Property Accountants Who Faced the Same Challenges You Do
RentalBux wasn't built in a Silicon Valley lab – it was born from the daily frustrations of a UK accountancy practice specialising in landlords and property investors, alongside sole traders & corporates.
When MTD arrived, we tried every platform on the market.
So we built RentalBux
The software we wished existed.
Every feature, every workflow, every report is designed by accountants who manage landlord and sole trader clients daily, not developers guessing what you might need. If you like to find more about our partner program.
Managing Clients Across Property, Self-Employment, and Mixed Income Shouldn't Mean Using Multiple Systems
Accountants with diverse client bases face a common problem. Generic accounting software lacks the property-specific features landlords need – particularly complex requirements like joint ownership and profit sharing. Property-specific platforms handle landlords well but offer no support for self-employment. The result? Juggling multiple systems, manual data entry, and no clear view of client progress across different income types and entity structures.
From April 2026, clients with property or self-employment income above £50,000 must submit quarterly MTD updates with digital records. Running separate systems for property clients and sole traders creates operational inefficiency and increases compliance risk.
RentalBux is purpose-built for accountants managing diverse client bases. Property management, self-employment accounting, and MTD workflows – all in one platform. A complete view of every client without switching systems or exporting data.
Everything You Need to Manage All Client Types – In One Place
RentalBux brings together property accounting, self-employment accounting, and MTD compliance in a single platform designed for accountants. No complicated setup. No data imports between systems. Just efficient client management from start to finish – across all income types and entity structures
Clear Workflow for Every Client Type
Client or accountant records rental income and property expenses through bank feeds, AI-powered letting agent statement imports, or manual entry. RentalBux categorises transactions automatically and allocates them to individual properties.

Your Clients Won't Arrive with Perfect Records.We've Planned for That.
RentalBux isn't generic accounting software with MTD bolted on. Every feature is designed to solve real problems accountants face daily – from automatic profit-split calculations to built-in workflow management and direct HMRC submissions.
RentalBux eliminates the manual work, workarounds, and wasted hours that come with managing MTD clients. Purpose-built features handle the complexity so you can focus on advising clients, not wrestling with software.
Handle joint ownership properties with any profit-sharing arrangement. Set the split once (60/40, 50/50, or any other ratio) and RentalBux automatically allocates income and expenses to each owner for accurate reporting and individual MTD returns.
What this means for you: Zero manual profit-split calculations. Accurate owner allocations with MTD returns ready for each party automatically.
Your Clients Won't Arrive with Perfect Records.
We've Planned for That.
Spreadsheets with missing columns. PDFs of bank statements. Letting agent reports in three different formats. RentalBux is designed for the reality of client data – not the ideal.
Most landlords and sole traders don't have digital records, consistent bookkeeping, or cloud-ready systems. That's not a barrier – it's exactly what we built for. Practical migration tools, flexible data imports, and AI-powered document extraction help you onboard any client, no matter where they're starting from.
Spreadsheet Import with Validation
Import client details, historical transactions, and opening balances from spreadsheets – for property clients, self-employment clients, or both. RentalBux validates data before import and highlights potential errors.
What this means for you: Catch data issues before they become problems. No nasty surprises after migration.
Bank Feeds with Historical Data
Connect client bank accounts and pull up to 12 months of historical transactions for property and self-employment clients alike. RentalBux categorises transactions automatically based on income type.
What this means for you: A 12-month head start on reconciliation without manual data entry.
AI-Powered Document Extraction
Upload PDFs and images of letting agent statements, bank statements, or other records. RentalBux uses AI to extract transactions automatically—recognising formats from major UK letting agents and banks.
What this means for you: The documents landlords and sole traders actually send – extracted in seconds, not hours.
Onboarding Support from Accountants Who've Done It
Our team includes practising accountants who've migrated their own clients to RentalBux. We'll help you plan your transition, troubleshoot issues, and get your first clients live without the guesswork.
What this means for you: Expert guidance from people who get your workflow—not generic scripts.
Let Clients Onboard Themselves
Invite clients to RentalBux and let them enter their own property details, tenant information, and historical records in one place. You review and approve – they do the data entry.
What this means for you: Shift the onboarding workload to clients. You focus on review, not data entry.
Connect with Clients Either Way
Add clients from your dashboard or get invited from theirs. Either way, instant access to their property details, transactions, and records—no duplicate setup or delays.
What this means for you: Flexible onboarding—you lead or the client does. One click, fully connected.
Your clients move forward without needing a clean slate – or months of cleanup work.
Is RentalBux Right for Your Practice?
Every practice is different. But if you're managing landlords, sole traders, or mixed-income clients – and you're tired of software that creates more work than it saves – RentalBux was built for you.
Sole Practitioners Juggling Too Many Systems
You're managing landlords, sole traders, and everything in between – but your software stack looks like a patchwork. One tool for property, another for self-employment, spreadsheets filling the gaps. RentalBux brings it all into one platform, so you spend less time switching systems and more time serving clients.
Growing Practices That Can't Afford to Add Headcount
Your client base is expanding, but hiring isn't an option yet. You need software that scales without scaling your admin time. RentalBux automates profit splits, MTD workflows, and client communications – so you can take on more clients without burning out.
Multi-Staff Firms That Need Visibility
You've got team members handling different clients, but no clear view of who's doing what. Deadlines slip. Work gets duplicated. RentalBux shows you exactly which staff member is handling which client, what stage they're at, and what's at risk – across every income type.
Larger Practices Ready to Standardise
You're managing hundreds of clients across property, self-employment, and companies. You need bulk operations, consistent workflows, and practice-wide reporting – not software that breaks at scale. RentalBux handles volume without compromising control.
Firms Preparing for April 2026 MTD
MTD for Income Tax is coming. Your landlord and sole trader clients will need quarterly submissions, digital records, and HMRC-compliant software. RentalBux is fully HMRC-recognised – one platform to make your entire practice MTD-ready before the deadline hits.
Fixed-Fee Practices Protecting Their Margins
MTD is about to increase your workload, but your clients expect the same fixed fees. RentalBux reduces time per client through automation, AI-powered data extraction, and streamlined workflows – keeping fixed fees sustainable even as compliance demands grow.
Whether you're a sole practitioner or a multi-partner firm
RentalBux flexes to fit your practice – not the other way around.

Requirements include: digital records, quarterly submissions, final declaration, and HMRC Recognised MTD Software. MTD compliance deadlines: Accountants must prepare clients earning over £50,000 for MTD by April 2026. Those earning £30,000-£50,000 follow in April 2027. MTD shifts client relationships from annual to quarterly engagement, creating an opportunity for practice growth and stronger client retention.
