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. Agencies using legacy systems that rely on manual reconciliation or spreadsheet-based landlord statements may face compatibility issues. 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. Agencies that have not migrated to MTD-ready platforms may face challenges in serving landlords subject to the new reporting requirements. 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.
