MTD if you’re employed with a side business

How MTD for Income Tax applies if you have a salaried job and a side business or rental income.

3 min read

Quick answer

Your salary doesn’t count towards the MTD threshold. Only your side business turnover and any property income do. If they add up to more than the threshold, you need MTD for that income, and you add your employment income in your final declaration as you do on a tax return now.

£24,000 freelance sales

£24,000

From April 2028, if this is your 2026/27 figure

£45,000

£16,000 sales and £20,000 rent

£36,000

From April 2027, if this is your 2025/26 figure

What you send

  • Quarterly updates for your side business and any property income

  • A final declaration that includes your employment income, taken from your P60 and P11D

Turnover, not profit

The test uses sales before expenses. A side business with £25,000 of sales and £15,000 of costs still counts as £25,000.
