Register and understand your obligations
Understand Your Tax Obligations
Know when you need to register and what you must declare.
When You Must Register for Self Assessment
You must register if your gross rental income (before expenses) exceeds £1,000 per year.
What Counts as Rental Income?
- Rent payments from tenants
- Payments for use of furniture
- Charges for additional services (cleaning, gardening)
- Rental income from garages or parking spaces
- Income from lodgers (over £7,500 - Rent a Room Scheme)
Tax-Free Allowances
- Property Allowance: £1,000 - if rental income is below this, no tax to pay
- Rent a Room Scheme: £7,500 - tax-free if letting a room in your main home
- Personal Allowance: £12,570 - applies to all income including rental
💡 Example:
Rental income: £15,000. Allowable expenses: £5,000. Taxable profit: £10,000. If you have no other income, you'd pay no tax (under personal allowance). If you're a basic rate taxpayer, you'd pay 20% = £2,000 tax.

Making Tax Digital
Comply with MTD requirements
Set Up Making Tax Digital
MTD is now mandatory for landlords with income over £10,000.
What is Making Tax Digital (MTD)?
MTD requires you to keep digital records and submit quarterly updates to HMRC using compatible software.
Who Must Use MTD?
- Mandatory: Gross rental income over £10,000 per year
- Voluntary: Can opt in if income is below £10,000
- Exemption: Only if you're digitally excluded (no internet access, religious reasons, age/disability)
Choosing MTD Software
You must use HMRC-approved software. Popular options for landlords:
- QuickBooks: £12-£24/month - comprehensive, good for multiple properties
- Xero: £12-£30/month - user-friendly, good integrations
- FreeAgent: £19/month - designed for small businesses
- Sage: £10-£26/month - established brand
- Free options: HMRC's own software (basic), some accounting software has free tiers
What You Must Do
- Keep digital records: All income and expenses must be recorded digitally
- Submit quarterly updates: Every 3 months, submit summary of income/expenses
- Submit End of Period Statement: After tax year ends, confirm figures are complete
- Submit Final Declaration: By 31 January, finalize your tax return
✅ Benefits of MTD:
- Spread workload across year (not one big task in January)
- Fewer errors - software does calculations
- Real-time view of tax position
- Better record-keeping

Allowable Expenses
Maximise your tax deductions
Track All Allowable Expenses
Know what you can and cannot claim.
Fully Allowable Expenses
These can be deducted in full from your rental income:
Property Running Costs
- Letting agent fees and management charges
- Buildings and contents insurance
- Utility bills (if you pay them, not tenant)
- Council tax (if you pay it)
- Ground rent and service charges
- Cleaning and gardening (if you provide these services)
Maintenance and Repairs
- Repairs to property (fixing existing items)
- Redecorating (painting, wallpapering)
- Replacing like-for-like (broken boiler, worn carpet)
- Maintenance of gardens and grounds
Professional Fees
- Accountancy fees
- Legal fees for tenancy matters (not purchase)
- Property management software subscriptions
- Membership of landlord associations
Other Allowable Costs
- Vehicle expenses for property-related travel (45p/mile for first 10,000 miles)
- Phone and internet costs (proportion used for rental business)
- Stationery and office costs
- Advertising for tenants
- Bank charges for rental account
⚠️ NOT Allowable:
- Improvements: Adding value (extension, new kitchen) - these are capital expenses
- Personal expenses: Your own mortgage, council tax on your home
- Capital costs: Purchase price, stamp duty, legal fees for purchase
- Mortgage capital repayments: Only interest qualifies (see next section)
Repairs vs Improvements
This is a common area of confusion:
| Repair (Allowable) | Improvement (Not Allowable) |
|---|---|
| Replacing broken boiler with similar | Upgrading to better boiler system |
| Replacing worn carpet with similar | Installing wooden flooring instead |
| Repainting walls | Adding an extension |
| Fixing broken window | Installing double glazing for first time |
Keep Every Receipt
Save all receipts and invoices digitally. Use your MTD software or a simple folder system. HMRC can ask for evidence up to 6 years later.
Understand Mortgage Interest Relief
The rules changed - you can no longer deduct mortgage interest.
How Mortgage Interest Tax Relief Works Now
Since April 2020, you cannot deduct mortgage interest from rental income. Instead, you get a 20% tax credit.
Old System (Pre-2020)
- Rental income: £20,000
- Mortgage interest: £8,000
- Other expenses: £2,000
- Taxable profit: £10,000
- Tax at 40% (higher rate): £4,000
New System (Post-2020)
- Rental income: £20,000
- Other expenses: £2,000 (mortgage interest NOT deducted)
- Taxable profit: £18,000
- Tax at 40%: £7,200
- Less 20% tax credit on £8,000 interest: -£1,600
- Total tax: £5,600 (vs £4,000 under old system)
⚠️ Impact on Higher Rate Taxpayers:
If you're a higher rate (40%) or additional rate (45%) taxpayer, you're significantly worse off under the new system. Many landlords have restructured through limited companies to avoid this.
Should You Use a Limited Company?
Limited companies can still deduct mortgage interest in full. Consider if:
- You're a higher or additional rate taxpayer
- You have significant mortgage interest
- You're buying new properties (easier to start in company)
- You don't need to extract profits immediately
Downsides of limited companies:
- Corporation tax (19%) + dividend tax when extracting profits
- More complex accounting (need accountant)
- Stamp duty surcharge on property purchases
- Capital Gains Tax when transferring existing properties
- More difficult to get mortgages
💡 Get Professional Advice:
Whether to use a limited company is complex and depends on your individual circumstances. Consult a specialist property accountant before making this decision.
