Making Tax Digital (MTD) for ITSA (Income Tax Self Assessment) is coming for UK landlords. The precise implementation dates are still being finalised by HMRC (His Majesty's Revenue and Customs), but the direction of travel is fixed - this is a mandatory regulatory requirement, not an option. Landlords who wait for a confirmed deadline will be under real pressure when it lands.

What MTD for ITSA Requires

MTD for ITSA mandates that landlords keep records in digital form and submit quarterly updates to HMRC throughout the tax year, replacing the single annual self-assessment return. In practice this means rental income, expenses, allowances, and supporting documentation must be logged and accessible in real time - not gathered in a folder at the end of the tax year.

The shift is material. Most landlords currently assemble records once a year, hand them to an accountant, and file by 31 January. Under MTD, your financial position must be reported every quarter. HMRC will see your income and expenses on an ongoing basis, not in retrospect.

Penalties for non-compliance apply, though HMRC's approach during early implementation is expected to include guidance and grace periods. The deadline for MTD for ITSA is TBC, but the preparation window is open now.

The Compliance Case and the Business Case

Accountants argue there's a second reason to act beyond avoiding penalties. Hazel Tucker, accountancy partner at Bishop Fleming, frames MTD not purely as a compliance burden but as a reset opportunity. The reasoning: landlords forced into quarterly reporting will, for the first time, see their financial position throughout the year rather than only after it ends.

Most landlords have no visibility of true profitability until the annual return is filed - by which point every decision in that tax year is already made. Quarterly updates create natural review points. You'll see your income and expenses every three months, which makes it easier to spot overspend, claim missed allowances, and catch errors before they compound.

For landlords with multiple properties or complex structures, this is a genuine operational upgrade. Lenders and buyers increasingly want clean, auditable financial records. MTD readiness is becoming a business asset, not just a regulatory cost.

What to Do Before the Deadline is Fixed

Speak to your accountant about your current record-keeping setup. What software do you use? Is it integrated, or are you transferring data manually between spreadsheets and an accounting package? Where are receipts and invoices stored? Are they dated and categorised?

You may wish to review your expense categories too. MTD will make every transaction visible quarterly. If you've been inconsistent with how you classify repairs versus improvements, or how you record mortgage interest, now is the moment to standardise before the reporting rhythm exposes the gaps.

Consider asking your accountant which MTD-compatible software suits your portfolio size. Not all accounting packages are MTD-ready, and migration takes time. Building that into your planning now avoids a last-minute scramble when the deadline is confirmed.
