Making Tax Digital for landlords

Making Tax Digital for Income Tax replaces the single annual Self Assessment return with four quarterly updates plus a year-end final declaration, all filed from software that talks directly to HMRC. Your records have to be kept digitally, and the path from those records to the submission has to stay digital.

What it does not do is change the tax. Your rates, your allowable expenses, the Section 24 finance cost restriction and your capital allowances all work exactly as before, all covered in our landlord tax guide. MTD changes when HMRC sees your numbers and how you submit them. The quarterly updates are categorised summaries of income and expenses, not tax calculations, so nothing becomes payable four times a year. Payment dates are untouched.

The practical shift is that bookkeeping stops being an annual January job. A landlord who reconciles once a quarter finds year-end quick and dull. A landlord who ignores it until the deadline is now doing that panic four times instead of once, with a penalty attached each time.

For the full mechanics, our guide to MTD for property income works through the regime end to end.

A digital record is each individual item of income and expenditure captured in software or in a spreadsheet, with its date, its amount and its category. Not a monthly total. Not a bank statement PDF filed in a folder. The categories follow HMRC's property schema, so rent received, finance costs, repairs and maintenance, insurance, professional fees and agent fees each sit in their own line.

You are not required to keep a digital image of every receipt, though scanning as you go is the easiest way to survive an enquiry. What you cannot do is break the digital link. If figures are retyped between the record and the submission, the chain is broken even if the final numbers are right.

Bank feeds do most of the work here. A feed that pulls transactions in automatically, with rules that code recurring items, turns quarterly filing into a short review rather than a data-entry session. Our guide to receipts, bank feeds and what counts as evidence sets out where the line falls.

Two separate regimes run alongside each other, and they stack. Late submissions attract points. Each missed quarterly update earns one point, and at four points a £200 penalty is charged, with a further £200 for every later missed submission while you sit at the threshold. Points clear after 24 months of compliant filing, measured from the most recent miss.

Late payment is charged differently. 3% of the unpaid tax at 15 days, a further 3% at 30 days, then 10% per annum accruing from day 31, with HMRC interest running separately from the original due date on top. On £10,000 of tax paid 180 days late, that is roughly £1,011 of penalty before interest.

The point worth internalising is that the £200 does not scale with your tax bill, but the late-payment percentages do. A small landlord who forgets a quarter faces a modest, fixable cost. A landlord with a real balancing payment who drifts past 31 January is in a different conversation entirely. The worked figures are in our page on MTD points and late-payment penalties.

Any competent accountant can file a quarterly update. The value is in what surrounds it. The threshold test on a mixed portfolio, the split on jointly owned property, the treatment of a property that stops being let mid-year, foreign rental income landing in the same cycle, and the year-end interaction between the finance cost restriction and capital allowances are all property-specific problems.

They also compound. A landlord wrongly told they were outside the regime spends a year without digital records, then has to rebuild them. A landlord whose software codes rent as trading turnover files twelve months of miscategorised updates before anyone notices. Both are avoidable at set-up and expensive afterwards.

Quarterly visibility is also the one genuine upside of MTD. If someone is looking at your numbers four times a year, a bad yield, a creeping cost base or an approaching tax bill surfaces while you can still do something about it.
