Setting Up and Submitting UK Property MTD ITSA Quarterly Returns in BrightBooks

1. What counts as a UK property business?

A UK property business generally includes:

• Rental income from UK residential or commercial property
• Furnished holiday lets in the UK (subject to HMRC rules)
• Other UK‑situated property income taxable in the UK

Once total qualifying income exceeds the MTD thresholds, UK property income must be recorded digitally and reported via quarterly updates .

2. Setting up a UK property business in BrightBooks

1. In BrightBooks, go to the client’s MTD ITSA settings.
2. Add a new UK property income source if one does not already exist.
3. Enter:
   • A descriptive name (e.g. “Smith – UK Property Business”)
   • Ownership share if required (for joint ownership)
   • Accounting method (Cash or Accruals)
   • Quarterly Period Type (Standard or Calendar)
4. Save the setup.

3. Recording UK property income and expenses

You can:

• Record detailed transactions in BrightBooks (rent charges, receipts, expenses)
• Or maintain detailed records in Excel and use the UK property bridging template (see Importing MTD UK Quarterly Returns Using Excel Template).

Key categories typically include:

• Rental income
• Agent fees and commissions
• Repairs and maintenance
• Insurance
• Allowable finance costs (interest)
• Other allowable property expenses

All transactions within the quarter will be aggregated into MTD categories when you generate the quarterly update.

4. Quarterly obligations for UK property

For each mandated landlord, MTD requires:

• A quarterly update for the UK property business showing:
  • Total UK property income
  • Total allowable expenses

These are not final tax figures; they provide an in‑year position and will be adjusted at year end as necessary .

5. Creating the UK property quarterly return

1. Ensure the UK property income source is set up and connected to HMRC (via MTD ITSA setup).
2. Go to General Ledger → MTD ITSA and select the UK property source.
3. Identify the open quarter and click Generate.
4. BrightBooks aggregates property income and expenses (including any imported Excel data) into the MTD summary.

6. Submitting to HMRC

1. Review the generated figures. If incorrect, amend underlying transactions or spreadsheets and regenerate.
2. Click Save, optionally Print for your records.
3. Tick the declaration and click Submit.
4. Monitor status from Open → Generated → Submitted → Fulfilled.

7. Handling corrections

If you discover an error after submission:

• Correct the underlying records and ensure the impact is reflected in a later quarterly update and/or in year‑end work, in line with HMRC guidance.
• Keep clear notes in your working papers to support any adjustments.
