Form 15G and Form 15H are forms you can submit to make sure TDS is not
deducted on your income subject to certain conditions. Form 15H is for those
who are above 60 years of age; while Form 15G is for others. These forms are
valid for one financial year. This means that you have to submit these forms
every year if you want to avail TDS exemption. Submitting them as soon as the
financial year starts will ensure the bank or other deductors do not deduct any
TDS on your income.
