About RentalBux
Property accounting software built by practising UK tax professionals for individuals, joint owners, sole traders, partnerships, LLPs and limited companies.
We Watched Landlords Drown in Spreadsheets. So We Built the Way Out.
UK Property Accountants spent nine years filing tax returns for landlords with portfolios of every shape and size. HMO landlords. Joint owners. Landlords with overseas income and self-employment on top. The same problems came up every April without fail: broken spreadsheets, missed joint ownership splits, and hours spent reconciling bank statements before a single figure could be submitted to HMRC.
Generic bookkeeping tools were not built for property income. They did not understand joint ownership. They could not handle UK and foreign property in a single return. They were not MTD-ready for landlords.
So in 2019, we stopped recommending workarounds and started writing code. RentalBux is the software we needed on day one of our practice.
“We set out to save our clients ten hours a month and ended up creating a platform that now serves over 10,000 landlords across the UK.”
