Chile’s tax authority set the daily interest rate for late payments at 0.022% for the first half of 2026, reflecting a slight decrease from last year and aligning with the updated law linking penalties to market rates.
Chile’s Internal Revenue Service (SII) issued Resolution No. 205 on 30 December 2025, setting the daily interest rate for late tax payments for the first half of 2026 (January – June 2026).
Under Law No. 21.713, the late payment penalty changed from 1.5% per month to a daily rate equal to the market interest rate plus 3.5%.
Resolution No. 205 sets this rate at 0.0220000000% from 1 January to 30 June 2026, slightly down from 0.0222222222% in the latter half of 2025.
The rate is calculated by adding 3.5% to the 4.42% base rate published by the Financial Market Commission on 15 December 2025, then dividing by 360. Interest is applied based on the rate in effect at the time of payment, regardless of when the tax arose.
Earlier, SII updated the daily interest rate for late tax payments is 0.0222222222% for the period from 1 July to 31 December 2025.
