What happens if I don't pay the DAS?
Missing DAS payments means losing social security benefits (retirement, sick leave, maternity). After 12 consecutive months without payment, the CNPJ can be automatically cancelled. Overdue payments accrue interest of 1% per month + 0.33% daily fine (capped at 20%). You can regularize through the Simples Nacional portal. See our CNPJ Validator to check your CNPJ status.
