Editorial
Tracking rental income and expenses accurately is not optional — it is a legal requirement. From April 2026, landlords earning over £50,000 must submit quarterly digital updates to HMRC under Making Tax Digital. Even if you fall below the threshold, accurate records are essential for your annual Self Assessment return, for understanding your true profitability, and for protecting yourself in the event of an HMRC enquiry.
Yet thousands of landlords still track their finances using shoeboxes of receipts, basic spreadsheets, or nothing at all. This guide explains what you need to track, how to track it efficiently, and how modern software like Latch makes the entire process automatic.
Why Accurate Tracking Matters
There are three compelling reasons to track your rental finances meticulously:
- Tax compliance: HMRC requires you to report all rental income and can request evidence of every expense you claim. Penalties for inaccurate returns range from 0% to 100% of the tax understated, depending on whether the error was careless or deliberate.
- Making Tax Digital: From April 2026, quarterly digital submissions are mandatory for landlords above the £50,000 threshold (£30,000 from April 2027). You need MTD-compatible software that maintains digital records and submits them electronically.
- Profitability: Without accurate tracking, you cannot know your true net profit per property. Many landlords discover they are losing money on a property only when they finally sit down and add up all the costs.
What Income to Track
All rental income must be reported to HMRC, not just the monthly rent. Here is a comprehensive list:
- Monthly rent payments
- One-off lump sum rent payments (e.g., tenant pays 6 months upfront)
- Insurance payouts for rent guarantee claims
- Charges for services provided (e.g., cleaning, laundry in an HMO)
- Income from letting parking spaces, garages, or storage separately
- Retained deposits used to cover damage (the portion used, not the full deposit)
- Any other income derived from the rental property
Deposits are not income: When you receive a tenant's deposit at the start of a tenancy, it is not income — it is held in trust. Only if you legitimately deduct from the deposit at the end of the tenancy (for damage beyond normal wear and tear) does the deducted amount become taxable income.
What Expenses to Track
Allowable expenses reduce your taxable rental profit. HMRC permits deductions for costs incurred wholly and exclusively for the purpose of letting the property:
| Category | Examples | Notes |
|---|---|---|
| Mortgage interest | Interest portion of mortgage payments | Tax credit at 20% basic rate only — not a direct deduction |
| Insurance | Buildings, contents, landlord liability, rent guarantee | Fully deductible against rental income |
| Repairs and maintenance | Plumbing, electrical, decorating, appliance repairs | Deductible if maintaining existing condition (not improving) |
| Agent fees | Letting agent management and tenant-finding fees | Fully deductible (but you can save this by self-managing) |
| Professional fees | Accountant, solicitor, landlord association membership | Fully deductible if for property business purposes |
| Travel | Mileage to property for inspections, maintenance, viewings | 45p/mile for first 10,000 miles, 25p thereafter |
| Office and admin | Stationery, phone calls, property management software | Proportionate business use if mixed personal/business |
| Safety certificates | Gas safety, EICR, EPC, legionella risk assessment | Fully deductible |
| Ground rent and service charges | Leasehold property charges | Fully deductible |
| Council tax (void periods) | Council tax when property is unoccupied between lets | Deductible during void periods only |
| Replacement of domestic items | Replacing furniture, appliances, kitchenware in furnished lets | Like-for-like replacement cost deductible (Replacement of Domestic Items Relief) |
Repairs vs improvements: Repairs restore the property to its previous condition and are deductible. Improvements make the property better than before and are capital expenditure (not deductible against rental income, but may reduce Capital Gains Tax when you sell). Replacing a broken boiler with a like-for-like model is a repair. Replacing a boiler with a higher-specification system is partly an improvement.
Software vs Spreadsheet
Many landlords start with a spreadsheet and wonder whether they need dedicated software. Here is an honest comparison:
| Feature | Spreadsheet | Property Management Software (e.g., Latch) |
|---|---|---|
| Cost | Free | £10–£30/month |
| MTD compatible | No — spreadsheets are not MTD-compatible software | Yes — digital records with quarterly submission |
| Automatic categorisation | No — manual entry for everything | Yes — transactions categorised automatically |
| Receipt storage | Separate folder or shoebox | Photograph and attach to transactions |
| Bank reconciliation | Manual comparison | Automatic bank feed matching |
| Error risk | High — formula errors, missed entries | Low — validation and automated calculations |
| Multi-property reporting | Complex — separate sheets or tabs | Built in — P&L per property with one click |
| Tax reports | DIY — extract and format manually | Generated automatically in SA105 format |
| Time required | 2–4 hours/month | 15–30 minutes/month |
MTD deadline: If your gross rental income exceeds £50,000, you must use MTD-compatible software from April 2026. Spreadsheets do not qualify. Even if you are below the threshold, switching to software now means less disruption when the £30,000 threshold applies from April 2027.
Bank Reconciliation
Bank reconciliation is the process of matching transactions in your records against your bank statement. It catches missed entries, duplicate recordings, and unexplained transactions. For landlords, this means checking that every rent payment received and every expense paid is accurately recorded.
Latch connects to your bank account via open banking and automatically imports transactions, matching them against expected rent payments and recorded expenses. This eliminates manual reconciliation for most transactions and flags any items that need your attention.
Receipt Management
HMRC can ask to see evidence for any expense you claim, going back up to 6 years (or 20 years if fraud is suspected). Every receipt, invoice, and contractor bill should be stored securely and linked to the corresponding transaction in your records.
- Photograph paper receipts immediately — thermal paper fades and becomes illegible within months
- Store digital receipts in a structured folder system or directly within your property management software
- Include the date, amount, supplier, and what the expense was for
- For mileage claims, keep a log of each journey with the date, destination, purpose, and miles driven
Quarterly Reporting for Making Tax Digital
Under MTD for ITSA, you must submit a quarterly update to HMRC showing your income and expenses for the period. The quarterly periods align with the tax year:
| Quarter | Period | Submission Deadline |
|---|---|---|
| Q1 | 6 April – 5 July | 5 August |
| Q2 | 6 July – 5 October | 5 November |
| Q3 | 6 October – 5 January | 5 February |
| Q4 | 6 January – 5 April | 5 May |
If your records are kept up to date throughout the quarter, the actual submission takes minutes with MTD-compatible software. Latch generates the quarterly summary automatically and submits it to HMRC through the MTD API with a single confirmation click.
Year-End Preparation
After the fourth quarterly submission, you must file a final declaration (End of Period Statement) that finalises your tax position for the year. This is your opportunity to make any adjustments, claim additional reliefs, and confirm the figures are correct.
- Reconcile all bank accounts against your records
- Verify all rental income has been recorded (compare against lease terms)
- Confirm all allowable expenses have been claimed
- Check mortgage interest figures against lender statements
- Review capital vs revenue expenditure classification
- Calculate Replacement of Domestic Items Relief claims
- Calculate mileage claims from your travel log
- Generate property-by-property P&L reports
- Review brought-forward losses from previous years
- Prepare figures for accountant or submit final declaration
