Rendered from the canonical facts model. General reference only — confirm with a qualified professional before acting.
Individuals pay the Imposta Generale sui Redditi (IGR) on a progressive scale of eight brackets from 9% to 35%. Bracket boundaries are revalued every two years against the cost-of-living index. Sources differ slightly on the intermediate bracket boundaries and rates, so a San Marino accountant should confirm the exact 2025 schedule.
