Frequently Asked Questions
Got questions? We've got answers.
The most common questions from RentalBux users — with links to detailed guides and demos.
What is MTD for Income Tax?+
Making Tax Digital requires landlords and self-employed to keep digital financial records and submit quarterly updates to HMRC. If your gross rental income exceeds £50,000, it becomes mandatory from April 2026. RentalBux handles the entire process. See the full MTD timeline →
Is RentalBux genuinely free?+
Yes. Landlords with one property get full access to all core features — including MTD compliance, income/expense tracking, bank reconciliation, and reporting — completely free until March 2028. No credit card required. Compare all plans →
Can I use it for jointly owned properties?+
Absolutely. Define profit-sharing ratios once, and the platform automatically splits rental income and expenses, generating clear reports and separate MTD submissions for each owner. See portfolio features →
Does RentalBux support overseas properties?+
Yes. RentalBux is HMRC-recognised for foreign property income, which is rare among property management platforms. Manage UK and overseas portfolios together. Learn more about MTD coverage →
How do I connect to HMRC?+
Go to Settings → HMRC Connection in the app and authorise via the Government Gateway. The process takes under 2 minutes. No spreadsheets or bridging software required. View the step-by-step walkthrough →
Is my data secure?+
RentalBux is GDPR compliant, SSL secured, and operated as an Appointed Representative of Finexer Ltd (FRN: 925695), authorised and regulated by the Financial Conduct Authority. Your data is encrypted and never sold.
Who built RentalBux?+
Created by UK Property Accountants — specialists who prepare tax returns for over 1,000 landlords. Built because generic tools don't understand Section 24, joint ownership, or MTD across multiple income streams. Watch the intro →
Can I use RentalBux if I'm also self-employed?+
Yes — the Sole Trader and Hybrid plans cover both rental property income and self-employment income under a single MTD submission. Compare plans →
