Executive Summary
The FTA has replaced Circular 18 with the updated version 18a, creating new flexibility for retirement provision. As of January 1, 2026, taxpayers can retroactively pay missing Pillar 3a contributions from 2025 and subsequent years – a significant relief for self-employed individuals and employees with irregular income. This regulation strengthens individual flexibility and increases transparency in retirement provision taxation.
