RentalBux vs. Bright
Which MTD Software Is Better for UK Landlords and Sole Traders?
Overall Winner: RentalBux
RentalBux is the more complete MTD software for landlords managing their own compliance. 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. Bright is a powerful alternative for accounting practices and bookkeepers who manage MTD filings on behalf of landlord and sole trader clients — its three-product ecosystem (BrightBooks for quarterly submissions, BrightTax for the Final Declaration, and BrightManager for practice workflow) is HMRC-recognised, cloud-based, and software-agnostic. However, Bright is designed for accountants rather than individual landlords, has no property-specific management features, and its pricing structure is geared toward practice-level subscriptions rather than individual self-filers.

What Is RentalBux? What Is Bright?
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.

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 Bright Handles MTD for Landlords and Sole Traders
Bright's MTD compliance is delivered through its two-product filing system. BrightBooks handles quarterly submissions to HMRC for both sole traders and UK property landlords, including simplified 3-line accounting for those below the VAT threshold. BrightTax handles the Final Declaration by retrieving all quarterly data directly from HMRC via API — this software-agnostic approach means BrightTax works regardless of which tool was used for quarterly filings, including Xero, QuickBooks, Sage, FreeAgent, Excel, or BrightBooks. BrightManager then provides oversight across all client obligations. Bright supports MTD for VAT across both BrightBooks and BrightTax. However, foreign property income support is not explicitly confirmed on Bright's website.

Winner: Depends on your role — For individual landlords self-filing, RentalBux wins with confirmed support for all three income types (including foreign property), a single integrated platform, and no need for multiple products. For accounting practices managing MTD across many clients using different software, Bright wins with its software-agnostic BrightTax, full Self Assessment and Corporation Tax capability, simplified 3-line accounting, and practice-wide workflow management.
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.
Bright: No Property-Specific Features — Accountant-Level Client Management Instead
Bright does not offer any property-specific management features. There is no property portfolio dashboard, no tenant management, no per-property rent tracking, no joint ownership automation, and no HMO-specific support. BrightBooks records rental income and expenses as standard bookkeeping entries. However, Bright compensates with practice-level features: BrightManager provides multi-client oversight, deadline tracking, automated client communications, and workflow management that helps accountants manage MTD compliance across their entire landlord client base simultaneously.
| Feature | RentalBux | Bright |
|---|---|---|
| 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 |

Winner: RentalBux for landlords. RentalBux is built for landlords managing properties. Any landlord who needs per-property tracking, tenant management, or joint ownership will find RentalBux dramatically more capable.
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.
Bright (BrightBooks): Full Bookkeeping Platform with Bank Reconciliation and Invoicing
BrightBooks is a comprehensive cloud-based bookkeeping platform — not just an MTD filing tool. It includes invoicing with customisable templates and recurring invoices, bank reconciliation with automatic statement imports, expense tracking, stock/inventory management, VAT returns, and client management. BrightBooks supports simplified 3-line accounting for sole traders and UK property landlords below the VAT threshold, allowing quarterly submissions at summary level without categorising every transaction. The platform generates profit & loss reports and provides at-a-glance financial dashboards. However, BrightBooks uses a general-purpose chart of accounts rather than a landlord-tailored one, and does not offer journal entries or double-entry bookkeeping in the traditional sense.
| Feature | RentalBux | Bright |
|---|---|---|
| Cash Basis Accounting | Yes | Yes |
| Chart of Accounts (Pre-built, Landlord-Tailored) | Yes (pre-built + custom) | No |
| Journal Entries | Yes | No |

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.
Bright (BrightBooks): Full Invoicing Platform with Recurring Billing
BrightBooks provides comprehensive invoicing with customisable templates, brand colours, product catalogues, and the ability to convert quotes and orders to invoices. Recurring invoices automate monthly billing. Online payment collection is supported, and bank reconciliation helps match payments to invoices automatically. Expense tracking covers vendor payments with status visibility and SEPA file generation for batch payments. However, BrightBooks does not offer AI-powered OCR receipt capture or automatic expense categorisation — these tasks rely on manual entry or bank feed categorisation.
| Feature | RentalBux | Bright |
|---|---|---|
| Invoice Creation & Sending | Yes | Yes |
| Invoice Customisation/Branding | Yes | Yes |
| Online Payment Collection | Yes | Yes |
| Payment Tracking/Reminders | Yes | Yes |

RentalBux produces structured financial reports including profit & loss statements, balance sheets, journal reports, ledger reports, and trial balances. Smart categorisation helps ensure accuracy.
Bright (BrightTax): Comprehensive Tax Compliance and Filing

It handles Self Assessment (SA100) tax returns, Corporation Tax (CT600), statutory accounts production (FRS 102 1A, FRS 105), iXBRL tagging, Companies House filing, and VAT returns. For the MTD Final Declaration specifically, BrightTax retrieves quarterly data from HMRC, compares it with the practice's own calculation, highlights any differences, and submits directly to HMRC. BrightBooks provides at-a-glance financial dashboards with drill-down capability for business insights.

Bright: Accountant-First Design with Practice-Wide Collaboration
Bright's entire ecosystem is built for accountants. BrightBooks includes unlimited users and a mobile app for iOS and Android, allowing accountants and their clients to collaborate on bookkeeping.

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 Bright Offers
Software-Agnostic Final Declaration (BrightTax)
BrightTax retrieves quarterly data directly from HMRC via API, meaning it works regardless of which software was used for quarterly filings — including Xero, QuickBooks, Sage, FreeAgent, Excel via bridging, or BrightBooks. This is Bright's key differentiator: clients keep their existing software, and BrightTax handles year-end.
Full Self Assessment, Corporation Tax & Accounts Production
BrightTax handles SA100 self assessment returns, CT600 corporation tax, statutory accounts production (FRS 102 1A, FRS 105), iXBRL tagging, and Companies House filing.
Practice Management with BrightManager
BrightManager provides workflows, task management, deadline tracking, automated client communications, onboarding tools, and time/profitability tracking across an entire accounting practice. This is designed for firms managing dozens or hundreds of clients through the MTD cycle simultaneously.
Simplified 3-Line Accounting
BrightBooks supports simplified 3-line quarterly submissions for sole traders and UK property landlords below the VAT threshold, allowing clients to report at summary level (turnover, allowable expenses, net profit) without categorising individual transactions.
MTD for VAT Support
Both BrightBooks and BrightTax support MTD for VAT, including Group VAT via BrightTax.
Extensive Third-Party Integrations
Bright integrates with Xero, QuickBooks, Sage, Zoho Books, FreeAgent, KashFlow, and ClearBooks.
26+ Years of HMRC Experience
Bright leverages over 26 years of experience with HMRC systems and manages more than 350,000 annual submissions, providing established compliance credentials.

Who Should Choose Bright?
Bright is the better choice for:
Accounting Practices Managing Many Landlord and Sole Trader Clients
Bright's three-product ecosystem is designed for practices managing dozens or hundreds of clients through the MTD cycle. BrightManager's workflow tools, deadline tracking, and automated client communications provide the oversight accountants need at scale.
Practices That Want Software-Agnostic Year-End Filing
If your clients use different quarterly filing software (Xero, QuickBooks, Sage, FreeAgent, Excel), BrightTax retrieves data from HMRC regardless — no need to standardise all clients onto one platform.
Practices Needing Full Tax Compliance Beyond MTD ITSA
BrightTax handles Self Assessment, Corporation Tax, statutory accounts production, Companies House filing, and VAT returns. If your practice needs a comprehensive tax compliance platform, not just MTD filing, Bright covers the full spectrum.
Practices with Clients at Different Digital Stages
BrightBooks supports clients from spreadsheet-traditionalists to cloud-first businesses. Simplified 3-line accounting lets less digital clients comply without categorising every transaction.
VAT-Registered Sole Traders and Landlords Working Through an Accountant
Bright supports MTD for VAT across BrightBooks and BrightTax. If your accountant already uses Bright products, adding MTD ITSA is a natural extension.
