Who needs to use MTD for Income Tax?

What SimplifyMTD does

How it works

  1. Connect to HMRC — Sign in with your Government Gateway credentials and authorise SimplifyMTD to connect to your HMRC account securely.
  2. Enter your income and expenses — Log your rental income and allowable expenses each quarter. Plain English categories, no accountancy knowledge needed.
  3. Submit your Final Declaration — At the end of the tax year, SimplifyMTD guides you through the Final Declaration which replaces your Self Assessment tax return and submits it directly to HMRC.

Why we built SimplifyMTD

SimplifyMTD was built by landlords who were tired of seeing fellow landlords quoted fees two to three times their normal tax return cost just to comply with MTD. Whether you are a small landlord with one property or managing several, MTD for property income does not have to be complicated. We built something genuinely simple so that anyone can use it, tested on our own families to make sure. No accountant needed, just a straightforward lower cost way for small landlords to meet their HMRC obligations.

Excel bridging software for landlords

SimplifyMTD can be used as Excel bridging software for landlords. If you keep your income and expenses in a spreadsheet, you can upload your Excel file directly and SimplifyMTD will read the totals, or you can simply enter the summed figures manually into the software. Either way, SimplifyMTD submits them straight to HMRC.

Frequently asked questions

Do I have to use Making Tax Digital?
HMRC is rolling out MTD for Income Tax in stages. From April 2026, it applies to self-employed people and landlords with income over £50,000. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028.
Do I still need an accountant to calculate my tax due?

No, and that's exactly why we built SimplifyMTD. Under Making Tax Digital, HMRC calculates your tax automatically based on the income and expense figures you submit. You don't need someone to do that calculation for you anymore. HMRC does it.

What landlords have traditionally paid accountants for — gathering the figures, submitting them to HMRC, and filing the annual return — is now something you can do yourself.

Is my data secure?

Yes. SimplifyMTD connects to HMRC using their official Making Tax Digital API — the same secure connection used by major accountancy software. When you sign in with your Government Gateway details, that happens entirely on HMRC's own website. We never see your password or login credentials at any point.

Your income figures are transmitted directly to HMRC over an encrypted connection. HMRC calculates your tax entirely on their side — we never store your tax calculation or share your financial data with any third party.

What if I have both UK and foreign property?
SimplifyMTD handles both UK and foreign property income in the same submission — you can manage everything in one place.
What if my income is below £50,000?
You don't need to use MTD yet, but you can still use SimplifyMTD voluntarily to familiarise yourself with the process before it becomes mandatory.
Do I have to submit tax returns every quarter?

No. Quarterly submissions are simple income and expense summaries.

HMRC calculates your tax after your Final Declaration, which replaces the Self Assessment return.
