Letting agents and landlords face a significant operational shift as the Making Tax Digital for Income Tax Self-Assessment (MTD for ITSA) deadline approaches on 6 April 2026, according to industry observers.
The new requirements will mandate landlords earning over £50,000 to submit quarterly digital updates to HMRC, expanding to those earning over £30,000 in 2027 and £20,000 in 2028. Matthew Gibbard, Director at Lettspay, has warned that many agencies remain unprepared for the transition.
Compliance requirements
The MTD framework requires what HMRC terms a ‘digital journey’, comprising digital record-keeping for every transaction, digital links between systems without manual data entry, and direct API-driven submissions via approved software platforms.
Agencies using legacy systems that rely on manual reconciliation or spreadsheet-based landlord statements may face compatibility issues. The regulations prohibit manual rekeying or copy-paste methods, requiring instead seamless integration with MTD-compliant software such as Xero, QuickBooks, or specialist property technology platforms.
Implementation timeline
HMRC has begun contacting landlords based on their 2024/25 tax returns. The migration process requires software verification against HMRC’s approved list, accurate categorisation of expense codes mapped to MTD categories, and data portability enabling landlords to transfer information directly into tax software.
According to Gibbard, the data migration process typically requires months rather than weeks to complete, involving the transfer of historical data, validation of live balances, and ensuring proper categorisation.
Market impact
The compliance requirements may affect the competitive landscape among letting agents. Agencies that have not migrated to MTD-ready platforms may face challenges in serving landlords subject to the new reporting requirements.
Landlords unable to meet quarterly submission deadlines through their current agent may face penalties, potentially prompting them to seek agencies with compliant systems already in place.
The implementation represents a shift in the operational infrastructure required for property management services, with digital tax compliance becoming a baseline requirement for agencies managing portfolios above the income thresholds.
