This can affect the return and may even delay the assessment. Some taxpayers also submit the form without checking whether all the required information has been properly included in the filled information.
Another common mistake is delaying the filing process until the last day or deadline. If a document is missing from your side or if the portal’s server is slow, there may not be enough time to fix the issue. It is always better to review the return once before submitting it altogether.
