Spreadsheets weren't built for quarterly HMRC updates, joint splits, or MTD for Income Tax.
It starts with one spreadsheet. Then come agent statements, mismatched PDFs, mortgage interest tracked by hand, joint ownership splits, and self-employment expenses mixed with rental income all rebuilt manually every quarter for Making Tax Digital.
4+ hrs
per property, per quarter
Chasing paperwork, not profit
Bank statements, letting agent PDFs, old emails. Every quarter you rebuild the same figures from scratch.
67%
of landlords still use spreadsheets
Spreadsheets hide mistakes
One broken formula, one missed row. Under MTD you are not catching errors. You are filing them to HMRC.
4×
more filing from April 2026
MTD multiplies the burden
Making Tax Digital for Income Tax requires quarterly HMRC submissions for income above £50k (dropping to £30k in 2027). The admin just quadrupled.
£2.4k
avg annual repair costs
Repairs drain time and money
Tracking maintenance costs across properties, chasing contractors and keeping receipts for tax relief is a second job.
42%
of landlords self-manage
Tenant admin never stops
Deposits, references, rent tracking, renewals. Without a system, critical dates slip through the cracks.
£200+
per missed MTD deadline
Non-compliance is expensive
Under HMRC's points-based system, each missed quarterly deadline adds a penalty point. Hit the threshold and every late submission costs £200, and escalates from there.
There is a better way.
