SRS Penalties and Late Interest in Latvia 2026 — What You Need to Know
Overdue tax payments create two additional financial obligations: late payment interest (accrues daily) and penalties (fixed or percentage of the violation amount).
Late Payment Interest — 0.05% per Day (max. 40% of principal)
For each overdue day, SRS charges 0.05% per day of the overdue tax amount (approximately 18.25% per year). Interest starts the day after the payment deadline and stops on the day of full payment.
40% cap (LNN art. 29 s.7): Late payment interest calculation stops when the total interest reaches 2/5 (40%) of the principal debt. At 0.05%/day this cap is reached after exactly 800 days.
- 1 day overdue on €1,000 = €0.50 interest
- 30 days overdue on €1,000 = €15.00 interest
- 365 days overdue on €1,000 = €182.50 interest
- 800 days overdue on €1,000 = €400.00 interest (cap reached — no further accrual)
Penalties — Three Scenarios
1. Late payment (no declaration violation): Only late interest — if the return was filed on time and the amount was correct, but not paid.
2. Late return filing: Penalty 1% of the calculated tax, minimum €71.14, maximum €711.44 per late month.
3. SRS audit finding: Penalty may be 5–30% depending on severity and whether it is a repeat violation.
Voluntary Correction — Reduces Penalty by 50%
If a taxpayer discovers an error and before SRS starts an audit files a corrected return and pays, the penalty is reduced by 50%. Act immediately — don't wait for SRS.
