Making Tax Digital with Multiple Businesses or Rental Income

If you run more than one sole-trader business, or combine self-employment with rental income, Making Tax Digital has one rule that catches people out:

Your income is combined to decide whether you are in scope, but your quarterly updates are separate for each business.

One threshold test

Qualifying income includes gross turnover from all your sole-trader businesses plus gross property income. A photographer earning £28,000, a weekend catering trade earning £9,000 and rental income of £16,000 has £53,000 of qualifying income. That crosses the £50,000 threshold even though none of the sources does alone.

Separate updates for each source

HMRC creates obligations for each business or property source. In the example above, the photographer should expect separate updates for photography, catering and property. Do not combine all three into one turnover and expense figure.

This is why the business identity shown by your software matters. Before submitting, check the business name, HMRC business ID, tax year and period. A correct number sent against the wrong business is still a wrong submission.

How to organise the records

You can use separate spreadsheets, separate tabs or one well-structured workbook. The important thing is that each source has a clear cumulative income total and expense total for the relevant period.

• Keep transactions assigned to the correct trade or property business.
• Do not count transfers between your own accounts as income.
• Use a consistent method for shared costs and keep your reasoning.
• Reconcile each source before its quarterly deadline.

What if a business starts or stops?

Tell HMRC when a business starts or ceases and keep records through the relevant date. A ceased source can still affect whether you crossed the qualifying-income threshold, particularly if another qualifying source continued. Check your obligations rather than guessing which updates remain due.

Property is not just another trade

UK property and foreign property are distinct sources, and jointly owned property requires your share of the figures. Property also has expense rules that differ from self-employment. Keep the records separate even if all income reaches the same bank account.

Using flonancial

When HMRC returns several supported businesses, flonancial presents them separately so you can submit the right spreadsheet totals against the right HMRC business ID. Its current quarterly lane is for straightforward sole-trader and UK-property figures using ordinary income and expenses. Complex adjustments or unsupported source types may require another compatible product or an accountant.

Start by checking HMRC's official explanation of qualifying income, then make a simple list of every business and the update due for each one.
