Welcome to MTD 4 Income Tax

MTD 4 Income Tax is a very easy to use Bridging Software for Sole Traders and/or a Landlords registered for Self Assessment who do not need an accountant or bookkeeper and it is currently under development aiming to become a HMRC-Recognised software at an affordable price.

It will be for free for the first 6 months and then £20.00 per year.

If you receive qualifying income from self-employment and/or property, you’ll be legally required to use Making Tax Digital (MTD) for Income Tax – based on the level of qualifying income – from the following dates:

  • April‌‌‌ 2026, if your qualifying income is over £50,000 in the‌‌‌ 2024‌‌‌ to‌‌‌ 2025‌‌‌ tax year
  • April‌‌‌ 2027, if your qualifying income is over £30,000 in the 2025 to 2026 tax year
  • April‌‌‌ 2028, if your qualifying income is over £20,000 in the‌‌‌ 2026‌‌‌ to‌‌‌ 2027‌‌‌ tax year

Because you'll be legally required to use Making Tax Digital (MTD) for Income Tax, you could get a penalty for not sending quarterly updates on-time.

With MTD 4 Income Tax Bridging Software you will be able to:
  • obtain business ID unique to each of the your businesses
  • maintain digital records of your tax affairs and be able to export them, if necessary
  • submit quarterly update information for each mandated business income source (self-employment, multiple self-employments, UK property income and/or foreign property income)
  • view an estimate of your income tax liability
  • make required adjustments and finalise business income for the year
  • brought forward, carry forward or set sideways (when permitted) business losses occurring in any one year as well as to apply losses incurred in earlier years against current year profits
  • receive nudges and prompts from HMRC
  • make a final declaration to submit a tax return

In this initial phase, the software is not able to submit any other income sources such as Dividends or Employment (PAYE) Incomes, but it is planned to add them after the software will be recognised by HMRC.

It is important to note, this software does not store any of your personal data in our systems. The only data the software stores in the servers is your email, password and national insurance number (both encrypted) to allow the login.

The software only stores the digital records in your device and can be exported or deleted at any time.
