Trusted by thousands of property owners 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.

Real challenges landlords face, and how RentalBux solves them

Real challenges Landlords face How RentalBux Solves It
Generic accounting tools aren’t tailored to rental or property businesses. RentalBux is built specifically for landlords, supporting both UK and foreign property portfolios.
Hard to juggle multiple income streams, properties, and shared-ownership structures. Manage multiple properties, units, and income streams in one dashboard with separate workspaces per business line.
Worried about MTD ITSA compliance and keeping digital records up to date. RentalBux is HMRC-recognised MTD software with digital records, quarterly updates, and submission workflows baked in.
Using spreadsheets and disconnected tools for property management, accounting, and tax. All-in-one platform for lease documents, rent tracking, bank feeds, and expense capture—no more fragmented workflows.
Scaling becomes messy when portfolios grow (HMOs, multiple owners, more units). Flexible pricing tiers and scalable workspaces support portfolios from a single unit to large, multi-owner holdings.
Manual bookkeeping is time-consuming and error-prone (missed rent, maintenance, double entry). Automated bank sync, rent scheduling, and real-time notifications cut admin time and reduce mistakes.
Accounting software costs are high for small landlords with just one property. RentalBux offers a free plan for one property until March 2028, removing the cost barrier for getting started.

Frequently Asked Questions

Making Tax Digital (MTD) for Income Tax is a UK government requirement for landlords to keep digital records of rental income and expenses, submit quarterly updates, and finalise their tax position through a year-end declaration using HMRC-recognised MTD software for landlords.
It applies to individuals earning rental income from residential, commercial, furnished holiday lets (FHLs), or overseas properties.

Read our complete guide to MTD for landlords
You must join MTD for Income Tax if:
  • You file a Self-Assessment for rental income
  • Your total property income (before expenses) exceeds £50,000 per year
  • Landlords earning below the threshold can continue with Self-Assessment but may join MTD earlier to simplify record-keeping, using MTD software for landlords.
See the full eligibility and exemption article
Landlords must submit 4 quarterly updates summarising rental income and expenses for each quarter of the tax year, and one final declaration to finalise the tax position, all done through MTD software for landlords. Deadlines and submission guidance
Under MTD, landlords must track each property individually, with income and expenses recorded separately so totals are accurate for the quarterly update and final declaration. RentalBux lets you manage multiple properties in separate ledgers, reducing manual work and errors.
Yes. All rental income counts toward the MTD threshold, including:
  • EU or overseas rental properties
  • Furnished holiday lets (UK or abroad)
  • If your total rental income (UK + overseas) exceeds £50,000, you must join MTD.
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)
