RentalBux finally gave me peace of mind.


Even after trying several tools, I was struggling with my portfolio of three rentals. MTD just added to that struggle. But then, I was introduced and all my worries disappeared. MTD submissions in minutes, track each property separately, allocate profit sharing. Wow!

Time saved.


Switching to RentalBux was one of the best decisions I made. Especially the joint-ownership module. Our family property had three owners with different shares, and RentalBux handled it quite efficiently.

Managing property expenses like repairs, maintenance, insurance, mortgage interest, and service charges can be scattered across invoices, emails, and spreadsheets.

Keeping up with MTD quarterly updates and year-end final declarations can be confusing. Guided workflows, reminders, and HMRC-recognised submissions make digital reporting simple, accurate, and stress-free.

FAQ Section Image
Making Tax Digital (MTD) for Income Tax applies to UK-resident landlords whose gross rental income exceeds £50,000 per tax year. The first mandatory compliance date is 6 April 2026. Landlords with income between £30,000 and £50,000 will need to comply starting April 2027. Learn more on who falls under the scope of MTD for UK landlords with UK Property income and when it starts.
For UK tax residents, qualifying income includes all rental income from your UK and foreign properties and self-employment income, before deducting any expenses. HMRC calculates the MTD income threshold on gross qualifying income, not net profit. This applies to all income under MTD for UK landlords with UK property income.
You must keep detailed digital records of all rental income and allowable expenses once you are under the scope of MTD. This includes rent received, insurance, mortgage interest, repairs, maintenance, utilities, professional fees, and management costs. HMRC requires these records to be stored digitally and easily accessible for quarterly updates. Using a structured digital ledger ensures all property income and expenses are correctly categorised, simplifies year-end reporting, and helps avoid errors or missed deductions.
UK landlords under MTD must submit quarterly updates every three months for their rental income and expenses. Each update summarises total income and outgoings, helping HMRC track your tax liability throughout the year. At the end of the tax year, landlords complete a final declaration, which reconciles all quarterly updates, reports other income streams if applicable, and applies allowable deductions. Submitting on time ensures compliance and reduces the risk of penalties.
Yes, spreadsheets are allowed if they are linked to HMRC-recognised bridging or accounting software. This combination ensures your digital records flow correctly into the system for quarterly updates and year-end final declarations. Simply keeping data in Excel or Google Sheets is not sufficient on its own; HMRC requires a compliant digital submission system. Using software like Rentalux that links directly with your spreadsheet ensures your rental income and property expenses are captured accurately, categorised in line with HMRC’s MTD rules, and automatically prepared for each quarterly submission.
Non-compliance with MTD rules can lead to penalties and interest charges. HMRC now uses a points-based system for late or inaccurate submissions. Failing to maintain digital records or submit quarterly updates on time increases the likelihood of fines. Compliance also ensures you can claim all allowable property expenses, avoid errors in your tax calculation, and maintain a clear audit trail. Staying digital-ready not only keeps you HMRC-compliant but also simplifies ongoing landlord accounting. To know the details on penalties of late submission and late payment read this article.
