Quick answer:
The best way to track rental income and expenses is with software that imports transactions from your bank automatically, categorises them by property, and keeps a running tax estimate ,so your records are always current and MTD-ready, even across a portfolio.
Why landlords need a better system
Rent arrives on different dates, expenses are scattered across repairs, fees, insurance and finance costs, and void periods complicate the picture. Spreadsheets buckle under this, especially with multiple properties. Automation keeps it organised without constant manual entry. Know exactly what you can claim with landlord allowable expenses.
What to track
- Rent received per property and per tenant.
- Allowable expenses: repairs, maintenance, letting fees, insurance, ground rent, service charges.
- Finance costs (recorded for relief at finalisation).
- Void periods and arrears, so your cash-flow picture is honest.
Track per property, not just in total
Seeing income and profitability by property ,not one merged figure ,tells you which parts of your portfolio are actually working. That’s invaluable for decisions about refinancing, selling, or expanding.
Staying MTD-ready
From April 2026, landlords over the threshold must keep digital records and file quarterly. A system that records everything as it happens turns each quarterly update into a quick review. See how this fits the rules in our MTD for landlords guide.
