Select the obligations that apply and enter the actual period-end date in AD. For a BS period, first verify the exact AD equivalent; the tool does not convert BS dates. The calculated dates use the normal statutory rule and do not include extensions.
VAT: generally within 25 days after the applicable tax period ends, under the VAT Act, sections 18–19. TDS: within 25 days after the payment month ends, under Income Tax Act, section 90. Confirm the taxpayer’s assigned VAT period, actual month-end and any official extension before using a date.

Annual, company, payroll and sector obligations
Add these after checking the applicable Act, registration, scheme and period. Record the legal due-date rule, source, original BS/AD date, assigned owner, reviewer and completion evidence. Company events, income-tax instalments and scheme-specific contributions cannot safely be derived from a generic month-end date.
Retain official extensions with the affected period and taxpayer category. A reminder, CSV row or bank debit does not prove that a return was filed or a contribution allocated.
