Formula and assumptions
Interest = Tax × annual rate × delay days ÷ 365.
- • CGST Act Section 50 uses interest for delayed tax; wrongly availed and utilised ITC is subject to the applicable notified rate and utilisation conditions.
- • Interest period and rate should be verified for the exact facts, notices and payment type.
- • Payment on or before due date gives zero delay days in this estimator.
