RentalBux vs. CCH iFirm MTD for Income Tax
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 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. CCH iFirm MTD for Income Tax, developed by global information services leader Wolters Kluwer, is a powerful alternative for accounting practices that need an enterprise-grade, HMRC-recognised cloud solution to manage MTD quarterly submissions, year-end adjustments, and final declarations across their entire client base — but it is designed exclusively for accountants and practices, not for individual landlords self-filing, and has no property-specific management features.

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 CCH iFirm MTD for Income Tax?
CCH iFirm MTD for Income Tax is an HMRC-recognised cloud module within the broader CCH iFirm Personal Tax product, developed by Wolters Kluwer Tax & Accounting. Wolters Kluwer is a global leader in information, software, and services with 2023 revenues of €5.6 billion, approximately 21,400 employees worldwide, and operations in over 40 countries. CCH iFirm has been driving impact globally for tax and accounting firms for over a decade and launched in the UK market in 2024 as the first European deployment.
CCH iFirm MTD for Income Tax fully supports the end-to-end MTD compliance lifecycle: importing income and expense data from cloud bookkeeping software (Xero, QuickBooks, Sage, FreeAgent) or from Excel spreadsheets via bridging, making quarterly submissions of sole trade and property income to HMRC, entering year-end adjustments, retrieving tax calculations from HMRC, and submitting the Final Declaration to complete the client's tax affairs for the year. The platform can also retrieve data submitted via other MTD software and display it within CCH iFirm, along with the status of quarterly obligations — meaning accountants can maintain oversight even when clients use different quarterly filing tools.

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 CCH iFirm Handles MTD for Landlords and Sole Traders
CCH iFirm MTD for Income Tax supports the full MTD lifecycle for sole trade and property income. The platform imports income and expense data from bookkeeping software or spreadsheets, automates quarterly submissions to HMRC, handles year-end adjustments, retrieves HMRC tax calculations for transparency, and submits the Final Declaration. The authorised agent process allows accountants to submit on behalf of clients. CCH iFirm can also retrieve and display data submitted via other MTD software, maintaining obligation oversight even in mixed-software environments. CCH Reporting includes dedicated scripts to identify which clients are mandated for MTD in April 2026, 2027, and 2028 based on their tax returns.

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.
CCH iFirm: No Property-Specific Features — Practice-Level Client Management Instead
CCH iFirm does not offer any property-specific features. There is no property portfolio dashboard, no tenant management, no per-property rent tracking, no joint ownership automation, and no HMO support. However, CCH iFirm compensates with practice-level capabilities: integration with CCH Reporting for identifying mandated clients, integration with CCH Central for on-premise accounting data, and the broader CCH iFirm suite for practice management, document management, and client communications.

CCH iFirm: Data Import and Compliance Hub — Not a Bookkeeping Platform
CCH iFirm MTD for Income Tax is not a bookkeeping platform. It imports income and expense data from external bookkeeping software (Xero, QuickBooks, Sage, FreeAgent) or from Excel spreadsheets via bridging templates. The platform then handles the compliance layer — quarterly submissions, adjustments, tax calculations, and the Final Declaration. CCH iFirm does not offer bank feeds, bank reconciliation, invoicing, or day-to-day bookkeeping features. Clients maintain their records in their chosen bookkeeping tool; CCH iFirm handles the HMRC submission process.

CCH iFirm: No Invoicing or Expense Tools — Compliance Submission Focus
CCH iFirm MTD for Income Tax does not include invoicing, expense tracking, receipt capture, or AI-powered features. These functions are handled by the client's bookkeeping software (Xero, QuickBooks, Sage, etc.), which then feeds data into CCH iFirm for submission. Wolters Kluwer has announced that invoice and receipt capture capabilities are coming soon as a planned feature, along with client portal integration and e-sign capabilities.

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.

Multi-Software Data Import (Xero, QuickBooks, Sage, FreeAgent)
