SimplifyMTD is free, HMRC recognised software that helps UK landlords comply with Making Tax Digital. Submit quarterly updates direct to HMRC. Final Declaration support is a planned feature and is not currently available. No accountant needed to file it yourself. While Final Declaration support is not yet available in SimplifyMTD, you can still use the platform for your quarterly updates. The Final Declaration can be completed at year end by your accountant — they can use your downloaded SimplifyMTD records as the starting point, which makes their work straightforward and keeps their fees focused on the year-end advice rather than data entry. If you do not use an accountant, you can use other HMRC-compatible software to file the Final Declaration. Your quarterly submissions remain valid regardless of which route you use.
Price: £0. Free forever. No trial, no card required, no paid tier.

This has been a game changer. Couldn’t find anything at first that did what I needed for property income and then found this. What a great job and idea, has made it possible for me to submit my information correctly and easily. Thank you for making this possible
Got recommended by a friend. Really impressed and made something quite frustrating a doddle.
Great system, so simple to use. I was very worried about MTD. This has been wonderful. Thank you.

Tax information is sensitive, so security is built into how SimplifyMTD handles sign in, your HMRC connection, and your property tax records. Passwords are protected with modern hashing and email-based multi-factor authentication, and access is further protected with login rate limiting, account lockout and secure server-side sessions. You authorise directly with HMRC via Government Gateway and never enter your Government Gateway password into SimplifyMTD. Sensitive identifiers and HMRC connection details are encrypted at application level, you can only ever access records linked to your own account, and your data is hosted on secure infrastructure located within the UK and European Economic Area. Read our full security overview.
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, free way for small landlords to meet their HMRC obligations.
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.
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.
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.
No. Quarterly submissions are simple income and expense summaries.
HMRC calculates your tax after your Final Declaration, which replaces the Self Assessment return.
