RentalBux vs. VitalTax
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. VitalTax is the UK's most widely discussed Excel bridging tool for MTD — an HMRC-recognised Microsoft Excel add-in developed by UK-based Vital Code, available from the Microsoft AppSource marketplace, that lets sole traders and landlords submit quarterly updates and the Final Declaration directly from their existing Excel spreadsheets for just £30 + VAT per year. Its defining strengths are exceptional affordability, zero workflow disruption for spreadsheet users, and one of the fastest submission experiences of any MTD tool. But as a pure submission bridge — with no property management, no bank feeds, no bookkeeping, no invoicing, no financial reports, and no landlord-specific features — VitalTax is a fundamentally different type of product to RentalBux and suits a very different user.

What Is RentalBux? What Is VitalTax?
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 VitalTax?
One solution for your Making Tax Digital compliance
VitalTax (vitaltax.uk) is an HMRC-recognised Microsoft Excel add-in developed by UK-based Vital Code. It is listed on HMRC's official register of compatible software and is available through the Microsoft AppSource marketplace. VitalTax has been used for MTD for VAT submissions for several years, establishing a reliable track record before extending to MTD for Income Tax ahead of the April 2026 mandatory rollout.
VitalTax's core proposition is minimal disruption and minimal cost. It installs directly inside Microsoft Excel as an add-in — no separate software to learn, no cloud platform to register for, no data migration. Users map cells in their existing Excel spreadsheet to the corresponding HMRC submission fields. When a quarterly deadline approaches, they open Excel, verify their figures are correct, and click submit. VitalTax reads the mapped cells, connects to HMRC's MTD API, and sends the quarterly update. The whole process typically takes under ten minutes once cell mappings are in place. VitalTax does not change how users keep their records — it simply transmits those records to HMRC in the correct digital format.

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 VitalTax Handles MTD Compliance
VitalTax supports all three qualifying income categories — self-employment (SA103), UK property (SA105), and foreign property income (SA106) — under a single annual licence. It operates exclusively as an Excel add-in: users maintain their income and expense records in their existing Excel spreadsheet using whatever layout they prefer, map the relevant summary cells to the HMRC submission fields within the VitalTax add-in, and submit quarterly updates directly to HMRC from within Excel. Each licence covers all four quarterly updates and the Final Declaration for every NI number included — with no per-submission charge.

|---|---|---|
| HMRC Recognised (MTD ITSA) | Yes | Yes |
| MTD Quarterly Updates | Yes | Yes |
| Final Declaration | Yes | Yes |
| Digital Record Keeping | 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: RentalBux — RentalBux is HMRC-recognised for all three qualifying income types and support agent filing and the Final Declaration. RentalBux adds full property management, automation, and a landlord-specific accounting layer 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.
VitalTax: No Property Management Capability
VitalTax is a submission tool only. It has no property portfolio tracking, no tenant management, no rent tracking per property, no joint ownership or profit-splitting, no compliance document alerts, no HMO support, and no mortgage tracking. VitalTax's scope is entirely limited to bridging a user's Excel records to HMRC's MTD system. Landlords using VitalTax manage all property operations and record-keeping entirely in their own Excel spreadsheets or separate tools — VitalTax only transmits the quarterly summary figures.
| Feature | RentalBux | VitalTax |
|---|---|---|
| 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 — VitalTax has no property management features of any kind. For landlords wanting to manage properties, tenancies, compliance certificates, and MTD filings in one place, RentalBux is the only viable option between these two.
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.
VitalTax: Your Spreadsheet Is the Record — VitalTax Is the Bridge
VitalTax makes no attempt to replace or augment the user's record-keeping. The user maintains their income and expense records however they choose — in a detailed Excel workbook, a basic spreadsheet, or any format they prefer. VitalTax's only role is to read the mapped cells and transmit summary figures to HMRC. This is explicitly stated in VitalTax's design philosophy: it does not categorise transactions, check figures, pull in bank feeds, or generate reports. The spreadsheet itself is the digital record — VitalTax is the MTD-compliant bridge. This places the entire accuracy and completeness of record-keeping responsibility on the user, which suits experienced, disciplined spreadsheet users but is a significant risk for those whose records are less organised.
| Feature | RentalBux | VitalTax |
|---|---|---|
| Cash Basis Accounting | Yes | No |
| Chart of Accounts (Pre-built, Landlord-Tailored) | Yes (pre-built + custom) | No |
| Journal Entries | Yes | No |
| Bank Reconciliation | Yes | No |
| 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 | No |
Winner: RentalBux for structured accounting, automation, and landlord-specific record-keeping.
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.
VitalTax: Submit Only — No Bookkeeping Features
VitalTax is explicitly and entirely a submission bridge. It has no invoicing, no expense tracking, no receipt capture, no bank feeds, no auto-categorisation, and no mileage tracking. As stated in the independent review at mtd.digital: VitalTax "does not create invoices, track payments, reconcile bank transactions, or generate financial reports." All of these functions must be handled by the user in their Excel spreadsheet or through separate tools. This is not a limitation unique to VitalTax — it is the defining characteristic of bridging software as a category.
| Feature | RentalBux | VitalTax |
|---|---|---|
| Invoice Creation & Sending | Yes | No |
| Invoice Customisation/Branding | Yes | No |
| Online Payment Collection | Yes | No |
| Payment Tracking/Reminders | Yes | No |
| Expense Tracking | Yes | No |
| Receipt Capture (OCR/Photo) | Yes | No |
| Expense Categorisation | Yes | No |
| Automated Transaction Matching | Yes | No |
| Mileage Tracking | No | No |
| AI Auto-Categorisation | Coming soon | No |
Winner: RentalBux — VitalTax has no invoicing, bookkeeping, or automation features. This is by deliberate design as a bridging tool. For landlords wanting these features, RentalBux is the appropriate choice.
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.
VitalTax: Tax Calculation Only — No Financial Reporting
VitalTax produces no financial reports of its own. Its post-submission output is the running tax calculation retrieved from HMRC — showing the user's estimated Income Tax and National Insurance liability based on the figures submitted. This is a single figure from HMRC, not a financial report or analysis. All historical financial reporting, profit & loss analysis, and portfolio performance tracking must be done by the user within their own Excel spreadsheet or separate tools.
| Feature | RentalBux | VitalTax |
|---|---|---|
| Profit & Loss Report | Yes (formal) | No |
| Balance Sheet | Yes | No |
| Trial Balance | Yes | No |
| Dashboard/Overview | Yes | No |
| Real-Time Financial Data | Yes | No |
| Cash Flow Reporting | No | No |
| Tax Estimate/Forecast | Yes | Yes |
| AI-Powered Features | Coming soon | No |
Winner: RentalBux — VitalTax produces no financial reports. RentalBux delivers formal accounting reports, per-property P&L, and a full financial dashboard that goes far beyond MTD submission.
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.
VitalTax: Agent Accounts and Excel on iPad
VitalTax supports agent accounts that allow accountants and tax agents to manage multiple clients from a single VitalTax account, submitting quarterly updates and Final Declarations on behalf of each client. An unlimited agent licence is available at £90 + VAT per year, covering any number of client NI numbers — making it exceptionally cost-effective for accountants managing large numbers of spreadsheet-based clients. VitalTax runs wherever Excel runs: Windows, Mac, Excel on the web, Excel on iOS, and Excel on iPad. There is no dedicated standalone mobile app. On mobile devices, access is via the Excel app with the VitalTax add-in installed.
| Feature | RentalBux | VitalTax |

| Accountant/Advisor Portal | Yes | Yes |
| Multi-User Access | Yes | Yes |
| Agent Filing on Behalf | Yes | Yes |

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.
VitalTax's Ease of Use
VitalTax is designed for experienced Excel users and is described consistently as very easy to use once configured. The initial setup involves installing the Excel add-in from Microsoft AppSource, authorising with HMRC via Government Gateway (a one-time step, renewable annually), and mapping spreadsheet cells to HMRC submission fields. After this one-time configuration, each quarterly submission typically takes under ten minutes. Trustpilot reviews (4.0 score, all positive) highlight ease of use and reliability. Submissions take under five minutes in practice. Some users on AccountingWEB have noted occasional delays in reaching support by phone or email, which is characteristic of a small developer team, and there have been infrequent reports of the add-in failing to load or showing erroneous HMRC unavailability messages — though these appear to be isolated and typically self-resolving. VitalTax does not collect, save, or record HMRC credentials, connecting to HMRC via their secure authorisation portal.
| Feature | RentalBux | VitalTax |

| Phone Support | Yes | No |
| Chat Support | Yes | No |
| Email Support | Yes | Yes |
| Help Centre/Knowledge Base | Yes | Yes |
| FCA Regulated | Yes | No |

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 VitalTax Offers
Works With Any Existing Excel Spreadsheet — No Templates
VitalTax is designed for users who have spent years building their own Excel-based record-keeping systems. Unlike some bridging tools that require users to adopt specific templates, VitalTax maps to whatever cells exist in any spreadsheet. The user selects the cells containing their quarterly totals and links them to the corresponding HMRC submission fields — no restructuring, no migration, no retraining. This is VitalTax's strongest and most distinctive feature.
HMRC Recognised for Both MTD for VAT and MTD for Income Tax
VitalTax is one of the few tools that handles both MTD for VAT and MTD for Income Tax under a single account and add-in. VAT-registered landlords and sole traders who already use VitalTax for their quarterly VAT returns can simply add Income Tax submissions to the same account.
Available via Microsoft AppSource — Inside Excel
VitalTax is available directly from the Microsoft AppSource marketplace as a certified Office add-in, appearing as a new ribbon tab inside Excel. For users who live in Excel, this is a natural fit: there is no separate app to open, no separate website to log into, and no context-switching between tools.
Ultra-Low Cost: £36/Year (inc. VAT) for One Individual
At £30 + VAT (£36 total) per year for one NI number, VitalTax is described by mtd.digital as "the cheapest bridging option for spreadsheet users" and "less than the cost of a single month's subscription to most full accounting platforms." For sole traders and landlords with well-organised spreadsheets, this represents genuinely transformative value — full MTD ITSA compliance, all income types, all four quarterly updates, and the Final Declaration, for £3 per month.
Unlimited Agent Licence at £90 + VAT/Year
Accountants and bookkeepers can purchase an unlimited licence for £90 + VAT per year covering any number of client NI numbers. This makes VitalTax one of the most cost-effective agent-level MTD tools available — particularly for practices that have large numbers of clients who already use Excel and do not need to be migrated to cloud accounting software.
Established VAT Track Record
VitalTax has been HMRC-recognised for MTD for VAT for several years before extending to Income Tax, and is described by mtd.digital as "the most widely discussed bridging tool in the MTD ITSA community." Forum discussions on AccountingWEB are broadly positive, with accountants consistently reporting reliable performance for VAT submissions. Trustpilot reviews (4.0 score) consistently praise ease of use and the fact that submission takes no more than five minutes once configured.
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 VitalTax?
VitalTax is the better MTD software choice for:
Experienced Excel Users Who Do Not Want to Change Their Workflow
VitalTax's defining strength is zero workflow disruption. If you have spent years building a detailed Excel workbook for your accounts and your records are accurate and well-organised, VitalTax lets you keep everything exactly as it is — and simply adds the MTD digital link to HMRC on top.
Sole Traders and Landlords Who Want the Absolute Lowest MTD Cost
At £36/year including VAT for one individual, VitalTax is one of the cheapest HMRC-recognised MTD options available. For users with well-organised spreadsheets who only need the submission bridge, no other tool matches this combination of recognised compliance status and minimal annual cost.
VAT-Registered Landlords Already Using VitalTax for VAT
For users already relying on VitalTax for their quarterly VAT returns, adding Income Tax to the same account is the path of least resistance — one tool, one login, one workflow for both tax obligations.
Accountants Managing Many Spreadsheet-Based Clients
The unlimited agent licence at £90 + VAT/year covering any number of client NI numbers is exceptionally cost-effective for practices with large numbers of clients who keep their own spreadsheet records. Accountants can submit on behalf of all clients from a single VitalTax account without requiring clients to adopt new software.
Multi-Property Landlords Who Only Need MTD Compliance — No Property Management
VitalTax has no property limit and no per-property charge. Landlords with multiple properties who already manage their records in Excel and have no need for property management, AI automation, or formal financial reporting will find VitalTax a straightforward and very low-cost compliance solution.
