The deadline for submitting Form 15G/H for the Financial Year 2020-21 was generally 15th April 2021, with some sources suggesting 30th April 2021. Submitting these forms after the deadline may result in Tax Deducted at Source (TDS) being applied to your income. While late submission might prevent TDS on future income, some TDS may still be deducted for the period it was furnished late. There is no indication of an extension due to COVID-19 for these forms.
