Why Property Accounting Matters
Every UK landlord who earns more than £1,000 per year in rental income must report it to HMRC. Getting this right isn't optional — it's a legal requirement with real penalties for non-compliance.
£100+ Penalties
Late Self Assessment filing incurs an immediate £100 fine, rising to £10 per day after three months — plus interest on any late payments.
5-Year Record Keeping
HMRC requires you to keep detailed records of all rental income and expenses for at least five years after the filing deadline.
Per-Property Tracking
While tax returns aggregate property income, tracking income and expenses at individual property level makes reporting far easier and helps your accountant prepare accurate returns — whatever your business structure.
What UK Landlords Can Claim
HMRC allows landlords to deduct "wholly and exclusively" business expenses from their rental income. Here are the key allowable expenses:
Note: For sole traders and partnerships, mortgage interest is no longer a deductible expense but qualifies for a 20% tax credit. Limited companies can still deduct mortgage interest in full. Capital improvements are not allowable for any structure.
Whether You're a Sole Trader, Partnership, or Limited Company
Every landlord structure has different tax obligations, reporting requirements, and accounting nuances. Rent Logger and Xero handle all three — so you get the right reports for the right tax return, every time.
Sole Trader Landlords
Individual property owners
Report rental income on SA105 (UK Property) pages of your Self Assessment tax return. Profits are taxed at your personal income tax rate (20%, 40%, or 45%).
How Rent Logger + Xero Helps
You own 3 buy-to-let properties generating £28,000/year. Rent Logger tracks every invoice, expense, and certificate renewal. At year-end, your accountant pulls a clean Xero report for each property and completes your Self Assessment in minutes, not days.
Partnerships
Joint property ownership & LLPs
The partnership files SA800 showing total income and how profits are split between partners. Each partner then reports their share on their personal Self Assessment (SA104).
How Rent Logger + Xero Helps
You and your business partner jointly own 8 properties across two limited liability partnerships. Rent Logger connects each LLP to its own Xero organisation, tracks income and expenses per property, and provides your accountant with clean, categorised data to prepare both the partnership return (SA800) and each partner's individual return.
Limited Companies
SPVs & property investment companies
Pay Corporation Tax (currently 25% for profits over £250k, 19% under £50k, marginal rate between) on rental profits. File a CT600 return annually. Mortgage interest remains fully deductible as a business expense.
How Rent Logger + Xero Helps
Your property investment company holds 12 residential units across 3 buildings. Rent Logger creates invoices under your company branding, pushes them to Xero with the correct tracking category for each unit, and gives you a company-wide P&L plus individual property breakdowns — ready for your accountant to file the CT600.

MTD replaces annual Self Assessment with quarterly digital reporting. If your gross rental income (plus any self-employment income) exceeds the threshold, you must use MTD-compatible software to keep records and submit updates to HMRC every quarter.

XeroBetter Together
We've built our Xero integration to make full use of tracking categories, account mapping, and automated invoicing — so your property finances are organised from day one.
Per-Portfolio Xero Organisations
Connect a different Xero organisation to each landlord portfolio. Invoices and payments automatically flow to the correct accounts — no manual sorting.
Tracking Categories Built In
Rent Logger automatically assigns the correct Xero tracking category to every invoice, mapping income and expenses to individual properties and blocks. This means your Xero reports break down by property out of the box.
Automated Invoice Generation
Rent invoices are created and pushed to Xero automatically on each rent due date — no double entry, no missed invoices, no human error.
Smart Account Mapping
During setup we help you map or auto-create Xero accounts for rent, holding deposits, security deposits, and other payment types so every transaction lands in the right place.
Property-Level Profit & Loss
Because tracking categories are applied consistently, you can generate Profit & Loss and Balance Sheet reports in Xero filtered down to a single property or block — giving your accountant the detail they need for accurate returns.
Contact Sync
Tenant contact details are synced to Xero automatically, keeping your accounting records up to date without any duplication of effort.
Branding Theme Support
Choose which Xero branding theme to use for each portfolio, so invoices carry the right logo and company details for each landlord entity.
Webhook Integration
Real-time webhook events from Xero keep Rent Logger informed of payment status changes, so your dashboard always reflects the latest position.
The Power of Tracking Categories
Xero's tracking categories let you tag every transaction with a property reference. Rent Logger sets this up automatically, so every invoice, payment, and expense is linked to the correct property from the moment it's created.
This means you can generate Balance Sheets and Profit & Loss reports in Xero filtered to a single property, a block of flats, or an entire portfolio — giving you and your accountant exactly the level of detail needed for HMRC reporting.

Your Compliance Checklist
Here's how Rent Logger and Xero together cover the key accounting and compliance requirements for UK landlords.
Digital Record Keeping
All rental income and expense data is stored digitally in Rent Logger and mirrored to Xero — satisfying HMRC's requirement that records be kept in MTD-compatible software.
Quarterly Reporting Ready
With every transaction categorised by property in Xero, your accountant can pull quarterly summaries in minutes rather than days. No last-minute scramble.
Per-Property Income & Expenses
Tracking income and expenses at individual property level gives your accountant the detail needed for accurate returns. Xero tracking categories handle this automatically — every invoice Rent Logger creates carries the property reference.
Self Assessment Support
At year end, Xero's tax reports (powered by Rent Logger data) give you everything you need for the SA105 UK Property pages on your Self Assessment return.
5-Year Record Retention
HMRC requires records to be kept for at least five years. Both Rent Logger and Xero retain full transaction history, giving you a clear audit trail.
Mortgage Interest Tax Credit
For sole traders and partnerships, mortgage interest is no longer a deductible expense but qualifies for a 20% tax credit. Limited companies can still deduct mortgage interest in full as a business expense — one of the key tax advantages of holding property through a company. Xero helps your accountant track and calculate this accurately alongside property-level data from Rent Logger.
