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 about our services and solutions.

Making Tax Digital (MTD) for Income Tax is the UK government’s digital reporting system for self-employed individuals and landlords. You must use HMRC-recognised software to keep digital business records, submit quarterly updates of income and expenses, and make a year-end final declaration. MTD aims to simplify tax filing for sole traders, freelancers, and contractors while improving accuracy in tax reporting. Read our full guide to MTD for sole traders
Not all self-employed people must join MTD immediately, but many will. You must comply if you are registered for Self-Assessment, earn income from self-employment, and your gross income exceeds £50,000. Those with income below this threshold can continue using traditional Self-Assessment but may join voluntarily. There are also exemptions for digital exclusion, e.g., due to health, age, or location. Eligibility and exemption articles
Yes, your accountant or tax agent can act on your behalf using MTD-compliant software, including digital record-keeping, quarterly submissions, and the year-end final declaration. However, you remain legally responsible for ensuring all MTD.
Under MTD for Income Tax, sole traders must submit quarterly updates summarising cumulative income and expenses for each self-employment stream. Updates are due one month after the end of each quarter. You don’t need to submit every invoice or receipt—just digital totals by category, supported by your digital business records.
Deadlines and submission guidance
After the tax year ends, you submit a final declaration under MTD, including all income, expenses, and any allowances or reliefs. The final declaration will replace the current Self-Assessment tax return, as it will include both mandated income (like property income) and non-mandated income (such as dividend and interest income).
For joint ownership, each landlord must:
  • Keep their own digital records
  • Submit their own MTD quarterly updates
  • Report their share of income and expenses (e.g., 50/50 split)
