Making Tax Digital
on autopilot
Upload your bank statements. AI categorises every transaction against HMRC SA105 rules. Review, approve, and submit your quarterly returns — all in one place.
Three steps to MTD compliance
No accountancy knowledge needed. We handle the HMRC rules.
Upload your bank CSV
Download a CSV from your bank and drop it in. We auto-detect Barclays, HSBC, Lloyds, NatWest, Monzo, Starling, Santander, and Nationwide.
AI categorises everything
Our AI engine maps every transaction to the correct HMRC SA105 box — rent income, repairs, insurance, letting agent fees, and more. Low-confidence items get flagged for your review.
Submit to HMRC
Review your quarterly summary, hit approve, and we submit directly to HMRC via the official MTD API. No HMRC login needed — we handle the connection.

Frequently asked questions
What is Making Tax Digital (MTD) for landlords?
From April 2026, landlords with property income over £50,000 must keep digital records and submit quarterly updates to HMRC instead of an annual self-assessment. This extends to £30,000+ from April 2027. LandlordTaxAi handles the entire process for you.
When are the quarterly deadlines?
The tax year runs 6 April to 5 April. Quarterly periods are: Q1 (6 Apr – 5 Jul), Q2 (6 Jul – 5 Oct), Q3 (6 Oct – 5 Jan), Q4 (6 Jan – 5 Apr). Each quarterly update is due one month after the period ends. An end-of-period statement and final declaration are also required.
Which banks do you support?
We auto-detect CSV formats from Barclays, HSBC, Lloyds, NatWest/RBS, Monzo, Starling, Santander, and Nationwide. We also have a smart fallback parser that works with most other CSV formats.
How does the AI categorisation work?
We use Claude AI to analyse each transaction description and map it to the correct HMRC SA105 box (rental income, repairs, insurance, letting fees, etc.). Every categorisation includes a confidence score. Items below 90% confidence are flagged for your review — the AI errs on the side of caution to protect you.
Is this actual tax advice?
No. LandlordTaxAi is a software tool that helps you organise and submit your property income data. It is not a substitute for professional tax advice. We always recommend consulting a qualified accountant for complex situations.
What about mortgage interest and Section 24?
We handle Section 24 correctly. Since 2020/21, mortgage interest cannot be deducted as an expense. Instead, it goes into Box 44 (residential financial costs) and you receive a 20% tax credit. Our AI categorises mortgage payments to the right box automatically.
Can I cancel at any time?
Yes. All subscriptions are monthly with no minimum commitment. Cancel from your Settings page and you'll retain access until the end of your billing period.
Is my data secure?
Your data is stored in a UK-region PostgreSQL database. HMRC OAuth tokens are encrypted at rest. We never store your bank login credentials — you upload a CSV export. All connections use TLS encryption.
