Incorporation is the start of the calendar, not the end of it. A startup still has to file income-tax returns, keep GST clean if it is registered, deduct TDS where it should, and meet ROC or LLP annual filings. Missing the first two years is how a young company collects notices before it has revenue.
Support is scoped to the stage of the venture — a simple ITR and bookkeeping pack for a pre-revenue team, or a fuller GST-plus-payroll desk once hiring and invoicing begin. The point is that statutory work runs on a list, not on memory.
