RentalBux vs. My Tax Digital
Which MTD Software Is Better for UK Landlords and Sole Traders?
Overall Winner: RentalBux
RentalBux is the more complete MTD software for landlords and sole traders. It combines full Making Tax Digital compliance across UK property income, foreign property income, and self-employment income with comprehensive property management, automated bookkeeping, AI-driven expense categorisation, joint ownership profit-splitting, and a free plan for single-property landlords until March 2028. My Tax Digital (Free) is a genuinely impressive free alternative — a web-based MTD compliance tool built by Open Answers, trusted by tens of thousands of users since 2019, and truly free for both VAT and Income Tax Self Assessment. But its deliberate simplicity, absence of property management tools, no AI automation, no mobile app, no landlord-specific chart of accounts, and no joint ownership support make it a less complete solution for landlords with complex or growing needs.

What Is RentalBux? What Is My Tax Digital?
What Is RentalBux?
All-in-One MTD Software for Landlords and Sole Traders
RentalBux is an all-in-one property management, accounting, and Making Tax Digital compliance platform built specifically for UK landlords, letting agents, and self-employed individuals. Designed with direct input from accountants who specialise in property and sole trader tax, RentalBux covers everything from tenancy management and rent collection to full bookkeeping with a pre-configured chart of accounts tailored to the property sector.
RentalBux is fully HMRC-recognised for Making Tax Digital for Income Tax across all three qualifying income categories: UK property income, foreign property income, and self-employment. This makes it one of the only landlord-specific MTD software platforms that can handle a landlord who also runs a sole trader business, all from a single subscription.
A major differentiator is RentalBux's pricing model: single-property landlords can use the platform completely free until March 2028, making it one of the most affordable HMRC-approved MTD software options for landlords entering the MTD regime.
What Is My Tax Digital ?
Trusted by tens of thousands to submit billions in returns since 2019
My Tax Digital (mytaxdigital.co.uk) is a free UK tax portal built and maintained by Open Answers Ltd — a company with over 35 years of experience in specialist Open Systems and Open Source services. Launched in 2019 as both a technical showcase and a social good, My Tax Digital was created on a founding principle: that forcing sole traders and landlords to pay a subscription just to fulfil their legal tax obligations is an unfair financial burden. Since launch, the platform has supported tens of thousands of businesses in submitting their MTD VAT returns, and has now extended this to full MTD for Income Tax Self Assessment support.
My Tax Digital operates in two modes. Bridging mode allows users who keep records in spreadsheets to upload their figures directly for submission to HMRC, establishing the required digital link without requiring them to change their existing workflows. Accounting mode allows users to maintain full digital records of income and expenses within the platform itself, with HMRC categorisation for self-employment (SA103S/F), UK property (SA105), and foreign property (SA106) built in. The platform also includes E-Invoicing, CSV data import and export, an AIsha AI assistant for help and guidance, and a Share Access feature allowing agents and accountants to manage filings on behalf of clients.

Making Tax Digital Compliance
How RentalBux Handles MTD Compliance
RentalBux supports all three MTD qualifying income categories: sole trader income, UK property income, and foreign property income. This makes it suitable for landlords who also earn self-employment income, eliminating the need for separate software. Most accounts are pre-mapped to HMRC Self-Assessment boxes. RentalBux also supports agent filing, allowing accountants or letting agents to submit MTD returns on behalf of their landlord clients.
How My Tax Digital Handles MTD Compliance
My Tax Digital supports all three qualifying income categories — self-employment (SA103S/F), UK property (SA105), and foreign property (SA106) — across both its Bridging and Accounting modes. In Bridging mode, users import their figures from spreadsheets via CSV or Excel and submit directly to HMRC. In Accounting mode, users record digital transactions within the platform, and My Tax Digital handles the categorisation and submission. Quarterly updates are submitted cumulatively — each update shows income and expenses from the start of the tax year up to the end of that quarter. The Final Declaration, which replaces the old Self Assessment return, is also supported.
| Feature | RentalBux | My Tax Digital |
|---|---|---|
| HMRC Recognised (MTD ITSA) | Yes | Yes |
| MTD Quarterly Updates | Yes | Yes |
| Final Declaration | Yes | Yes |
| Digital Record Keeping | Yes | Yes |
| Digital Links Compliant | Yes | Yes |
| Sole Trader Income | Yes | Yes |
| UK Property Income | Yes | Yes |
| Foreign Property Income | Yes | Yes |
| Multiple Income Streams | Yes | Yes |
| Agent Filing on Behalf | Yes | Yes |
Winner: Tie on core MTD compliance — Both platforms are HMRC-recognised for all three qualifying income types and support agent filing. My Tax Digital adds MTD for VAT and bridging mode. RentalBux adds AI automation, landlord accounting structure, and property management tools around the same compliance core.
Property Management
RentalBux: Property Management
RentalBux provides comprehensive property portfolio management with tenant management, rent tracking, property expense allocation, and support for multiple properties. A standout feature is its joint ownership and profit-sharing capability: landlords can define ownership percentages once, and RentalBux automatically splits rental income and expenses. RentalBux also supports HMO properties, automatically creating individual units.
My Tax Digital: No Property Management Capability
My Tax Digital was designed as a compliance and filing tool, not a property management platform. It does not include property portfolio tracking, tenant management, rent tracking per property, joint ownership or profit-splitting, compliance document alerts, HMO support, or mortgage tracking. Its strength lies entirely in MTD compliance — keeping digital records and submitting returns to HMRC — rather than the operational management of a property business.
| Feature | RentalBux | My Tax Digital |
|---|---|---|
| Property Portfolio Management | Yes | No |
| Tenant Management | Yes | No |
| Rent Tracking | Yes | No |
| Property Expense Allocation | Yes | No |
| Multiple Property Support | Yes | No |
| HMO Property Support | Yes (auto-creates units) | No |
| Joint Ownership/Profit Sharing | Yes (auto-split by %) | No |
| Maintenance Tracking | No | No |
| Tenant Screening | No | No |
| Compliance Document Alerts | Yes | No |
| Arrears Tracking | No | No |
Winner: RentalBux — My Tax Digital is a compliance tool, not a property management platform. For landlords wanting to manage properties, tenancies, compliance certificates, and MTD filings in one place, RentalBux is the clear choice.
Bookkeeping, Accounting & Digital Record Keeping
RentalBux: Structured Accounting
RentalBux includes a pre-built chart of accounts specifically designed for landlords and sole traders, covering rental income, mortgage interest, insurance, property repairs, professional services, utilities, and tenant deposits. All accounts are pre-mapped to HMRC Self-Assessment boxes. The platform supports cash basis accounting, bank reconciliation, and journal entries.
My Tax Digital: Simple, Category-Based Digital Record Keeping
My Tax Digital's Accounting mode provides digital record keeping for income and expenses, correctly categorised against SA103, SA105, and SA106 HMRC categories. Users can import bank transactions via CSV, manually add transactions, and categorise them within the platform. The categorisation ensures quarterly updates and the Final Declaration contain the figures HMRC expects. However, My Tax Digital does not offer a formal chart of accounts, journal entries, double-entry bookkeeping, or property-level P&L reporting. It is designed to satisfy the digital record-keeping requirement as simply as possible — not to replace a full accounting package.
| Feature | RentalBux | My Tax Digital |
|---|---|---|
| Cash Basis Accounting | Yes | Yes |
| Chart of Accounts (Pre-built, Landlord-Tailored) | Yes (pre-built + custom) | No |
| Journal Entries | Yes | No |
| Bank Reconciliation | Yes | Yes |
| Automated Bank Feeds | Yes (Major UK banks) | No |
| Open Banking Integration | Yes | No |
| Double-Entry Bookkeeping | Yes | No |
| HMRC Box Pre-Mapping | Yes | Yes |
| Xero Integration | No | No |
| Spreadsheet Import/Export | Yes | Yes |
| Digital Record Storage | Yes | Yes |
Winner: RentalBux for landlords wanting full accounting structure. My Tax Digital for landlords who want to keep their spreadsheets and simply bridge them to HMRC. The right choice depends on whether you want accounting software or a pure compliance submission tool.
Invoicing, Expense Tracking
RentalBux: Expense Management
RentalBux includes OCR receipt capture, structured expense tracking with landlord-specific categories, auto-categorisation, invoice creation with customisable branding, and payment tracking with reminders.
My Tax Digital: E-Invoicing and Manual Record Entry
My Tax Digital includes a basic E-Invoicing feature allowing users to create, preview, download, and reconcile invoices — helping ensure digital records remain complete and MTD-compliant. Expense tracking is manual: users enter or import transactions via CSV, and the platform handles categorisation against the correct HMRC category. There is no OCR receipt capture, no automated bank feeds via open banking, and no AI automation. My Tax Digital's AIsha AI assistant is available to provide guidance and answer questions about using the platform, but it does not automate data entry or categorisation.
| Feature | RentalBux | My Tax Digital |
|---|---|---|
| Invoice Creation & Sending | Yes | Yes |
| Invoice Customisation/Branding | Yes | Yes |
| Online Payment Collection | Yes | No |
| Payment Tracking/Reminders | Yes | No |
| Expense Tracking | Yes | Yes |
| Receipt Capture (OCR/Photo) | Yes | No |

| AI Auto-Categorisation | Coming soon | No |
Winner: RentalBux for landlords wanting automation and minimal manual input. It provides payment tracking & reminders, receipt capture (OCR) and automated transaction matching.
Reporting & Tax Forecasting
RentalBux: Formal Accounting Reports
RentalBux produces structured financial reports including profit & loss statements, balance sheets, journal reports, ledger reports, and trial balances. Smart categorisation helps ensure accuracy.
My Tax Digital: Compliance-Focused, No Financial Reporting
My Tax Digital does not produce profit & loss statements, balance sheets, or financial reports in the traditional accounting sense. Its output is structured for MTD compliance: it shows submitted quarterly figures and running cumulative totals per income category as required by HMRC. It does not provide portfolio-level reporting, per-property analysis, or any investment analytics. Landlords who need financial reports beyond their MTD submissions — for example for mortgage applications, accountant reviews, or business planning — would need to maintain those records separately.
| Feature | RentalBux | My Tax Digital |
|---|---|---|
| Profit & Loss Report | Yes (formal) | No |
| Balance Sheet | Yes | No |
| Trial Balance | Yes | No |
| Dashboard/Overview | Yes | Yes |
| Real-Time Financial Data | Yes | Yes |
| Cash Flow Reporting | No | No |
| Tax Estimate/Forecast | Yes | No |
| AI-Powered Features | Coming soon | No |
Winner: RentalBux — My Tax Digital provides no financial reporting beyond the data submitted to HMRC. RentalBux delivers formal accounting reports, per-property P&L, and a full financial dashboard that goes far beyond MTD compliance.
Collaboration & Mobile Apps
RentalBux's Collaborative Features
RentalBux enables agent filing, which gives accountants and letting agents the ability to submit directly on a landlord's behalf.
My Tax Digital: Share Access, Agent Accounts, and Web-Based Mobile Use
My Tax Digital supports accountant and agent access through its Share Access feature — users share access with their accountant using the accountant's registered My Tax Digital email address. Agents and accountants can manage unlimited businesses and individuals from a single account, switching between client profiles seamlessly. This makes My Tax Digital a genuinely practical tool for accountants managing many clients at zero cost. My Tax Digital is a web app and does not have a dedicated native mobile app for iOS or Android; however, it is optimised for use in mobile web browsers.
| Feature | RentalBux | My Tax Digital |
|---|---|---|
| Accountant/Advisor Portal | Yes | Yes |
| Multi-User Access | Yes | Yes |
| Agent Filing on Behalf | Yes | Yes |
| Bank Integration | Yes | Yes |
| Platform | iOS, Android | Web browser only |
| Web Browser Access | Yes | Yes |
| FCA Regulated | Yes | No |
| GDPR Compliant | Yes | Yes |
Winner: Tie — Both platforms support agent filing and multi-user collaboration. RentalBux leads on native mobile apps. My Tax Digital leads on unlimited client management at zero cost, making it particularly practical for accountants managing large numbers of straightforward clients.
Ease of Use, Support & Security
RentalBux: Guided Workflows
RentalBux uses guided workflows, clear dashboards, and no accounting jargon. The platform offers phone support, email/chat support, and a help centre with guides and knowledge base articles.
My Tax Digital: Ease of Use
My Tax Digital is a web-based application requiring no download. Its interface is deliberately simple, reflecting its focus on compliance rather than comprehensive accounting. The platform includes a detailed documentation hub with step-by-step guides and video walkthroughs on YouTube. Customer support is provided by email (mytaxdigital@openanswers.co.uk). The AIsha AI assistant is available within the platform for immediate guidance.

RentalBux Features
Sole Trader Income Support for MTD
RentalBux is one of the few landlord-focused MTD software platforms that supports self-employment income alongside UK and foreign property income within a single account. Landlords who also run a trade, consultancy, or freelance business can manage all quarterly submissions from one dashboard. Landlord Studio covers property income only.
Custom Chart of Accounts for Landlords
A property-tailored chart of accounts covering rental income, mortgage interest, insurance, repairs, utilities, letting agent fees, and more — all pre-mapped to HMRC Self-Assessment boxes. No setup required; the system is ready to use from day one. Landlord Studio has no equivalent.
Agent Filing on Behalf of Landlords
Letting agents and accountants can submit MTD quarterly updates and the Final Declaration on behalf of landlord clients directly from the platform. Landlord Studio allows accountant access but does not support submission on the landlord's behalf.
Branded Invoice Creation
Invoice creation with customisable branding for service charges and commercial landlords. Not available in Landlord Studio.
AI-Powered OCR Receipt Capture with Auto-Categorisation (Coming soon)
RentalBux's AI will read uploaded receipts and categorise the expense automatically against the pre-built chart of accounts. Landlord Studio's Smart Scan extracts dates and amounts but does not include AI-driven expense categorisation.
Formal Accounting Reports
Balance sheet, trial balance, ledger reports, and journal reports. Landlord Studio does not produce these natively.
Free Plan Including MTD Submissions Until March 2028
RentalBux's free single-property plan includes MTD quarterly submissions. Landlord Studio's free GO plan covers property management for up to three units but requires a paid PRO plan (from £12/month) to access MTD submission functionality.
Unique Features Only My Tax Digital Offers
Completely and Permanently Free — No Subscriptions, No Hidden Charges
My Tax Digital is entirely free for both MTD for VAT and MTD for Income Tax Self Assessment. There are no premium tiers, no feature paywalls, and no hidden fees. My Tax Digital is free for everyone, with no expiry date and no property limit.
MTD for VAT — Free
My Tax Digital covers all MTD for VAT submissions at no cost, supporting Standard Accounting, Cash Accounting, Flat Rate, and Margin Scheme. For VAT-registered landlords or sole traders who need both MTD for VAT and MTD for Income Tax from one free platform, My Tax Digital is a good option.
Bridging Software Mode
My Tax Digital's Bridging mode allows users to continue keeping records in their existing spreadsheets and submit those figures to HMRC directly — establishing the required digital link without migrating to a new system. It accepts .xlsx, .xls, .ods, .csv, and .numbers files.
Enterprise-Grade Security Credentials
Open Answers, the company behind My Tax Digital, holds ISO 27001:2022 certification for information security management, Cyber Essentials Plus certification, and a Royal Warrant as Supplier of Information Technology Services By Appointment to HM The King. All data is stored in secure UK-based data centres. These credentials are exceptional for a free tool and reflect Open Answers' 35+ years of enterprise IT services experience.
AIsha AI Assistant
My Tax Digital includes AIsha — an AI assistant embedded in the platform to answer questions and guide users through the MTD filing process. AIsha helps users navigate the platform, resolve common issues, and understand their HMRC obligations, making the platform more accessible for users with limited accounting knowledge.
No Property Limit on Free Plan
My Tax Digital's free plan has no property limit. Landlords with multiple properties can use My Tax Digital entirely for free — they would need to manage per-property records manually, but the platform imposes no restriction on the number of properties or individuals managed.
Who Should Choose RentalBux?
RentalBux is a strong fit if you:
Landlords with Mixed Income Streams
If you earn from both property and self-employment, RentalBux handles sole trader income alongside UK and foreign property income in a single MTD-compliant platform.
Joint Owners and Family Portfolios
The automated profit-sharing split is a standout feature. Define ownership percentages once and RentalBux calculates each owner's share automatically.
Budget-Conscious Landlords Entering MTD
Free MTD software for single-property landlords until March 2028, with no upfront commitment.
Landlords Who Want Proper Accounting Structure
Chart of accounts, journal entries, profit & loss, balance sheet, and trial balance give RentalBux a structured accounting foundation.
Accountants and Letting Agents
Agent filing on behalf, multi-user access, and spreadsheet import make RentalBux practical for professionals managing multiple landlord portfolios.
Commercial Landlords and HMO Owners
Invoice creation with branding for service charges, plus automatic HMO unit creation and tenant management.
Who Should Choose My Tax Digital?
My Tax Digital is the better MTD software choice for:
Landlords and Sole Traders Who Want Zero Cost with No Restrictions
For users who need MTD compliance and nothing else, and for whom cost is the primary consideration, My Tax Digital is the only platform in this comparison that is genuinely and permanently free with no property limit and no expiry date.
Landlords Who Are Comfortable with Spreadsheets
My Tax Digital's Bridging mode is ideal for landlords who already keep accounts in Excel or another spreadsheet and want to continue doing so. Submit your figures to HMRC via My Tax Digital without migrating to new software or changing existing workflows.
VAT-Registered Landlords and Sole Traders
For users who need both MTD for VAT and MTD for Income Tax from a single free platform, My Tax Digital is uniquely positioned — it handles both at no cost.
Accountants Managing Many Straightforward Clients at Zero Cost
My Tax Digital's unlimited individuals/businesses on a free plan makes it an extremely cost-effective tool for accountants whose clients have straightforward income and do not need property management, AI automation, or detailed reporting.
Users Who Prioritise Enterprise-Grade Security Credentials
ISO 27001:2022 certification, Cyber Essentials Plus, and a Royal Warrant from HM The King provide a level of independent security assurance that is remarkable for a free tool — and may matter to users handling sensitive financial data.
Users with Simple, Single-Source Income
Sole traders or landlords with one income stream and limited transaction volumes who simply need to keep digital records and file quarterly updates will find My Tax Digital's straightforward interface more than sufficient.
