Why Dentists Rely On Us
Trusted by thousands of dentists across the UK
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!
Built for landlords, used by landlords.
As a landlord managing 12 units across two ownership structures and some self-employment income, I needed something that handled everything. RentalBux was the only software that did that.
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.

Frequently Asked Questions
Find answers to common questions
Yes. UK-resident dentists and dental professionals whose gross qualifying income exceeds £50,000 must comply with Making Tax Digital for Income Tax. From 6 April 2026, dentists under the scope of MTD are required to maintain digital accounting records and submit quarterly MTD updates to HMRC.
Qualifying income includes revenue generated by your dental practice and the rental income from UK or foreign property. HMRC calculates the MTD threshold on gross dental practice and property rental income, not net profit, so all sources of practice income must be tracked digitally. <a href="/blogs/making-tax-digital-for-income-tax-exemptions">Eligibility and exemption article</a>
Dentists must keep detailed digital records of income and expenses, including:
<ul>
<li>Patient fees (NHS, private, cosmetic) </li>
<li>Staff salaries and payroll </li>
<li>Dental supplies and laboratory costs </li>
<li>Rent, utilities, and insurance </li>
<li>Professional fees, training, and equipment costs </li>
</ul>
Records must be easily accessible for quarterly updates and for year-end final declarations under MTD rules. Maintaining structured ledgers helps simplify HMRC-compliant dental accounting.
Dentists must submit quarterly MTD updates every three months, summarising all practice income and expenses. At year-end, a final declaration reconciles the quarterly submissions, includes any other revenue streams, and applies eligible deductions. Staying up to date ensures compliance with HMRC and reduces the risk of penalties.
Yes, but spreadsheets alone are not enough. HMRC requires data to flow digitally into MTD-compliant software. Integrating spreadsheets with recognised MTD software allows dentists to automatically track income, categorise expenses, and prepare quarterly submissions and year-end declarations efficiently.
Non-compliance can result in <a href="blogs/autumn-budget-2025-confirms-no-mtd-quarterly-penalties-in-first-year">points-based penalties</a> , interest charges, and disallowed expenses. Accurate digital records ensure full HMRC compliance, simplify audits, and make quarterly MTD reporting and year-end tax filing easier and less stressful for dental practices.
