Individuals file online on the income tax e-filing portal, choosing the right form (such as ITR-1 or ITR-2) for their types of income. The usual deadline for people whose accounts do not need an audit is 31 July after the end of the financial year. Filing on time lets you claim refunds and carry forward losses.
