Form 122 | Income Declaration to Employer for Salary, Other Income & TDS
If you switched jobs in the same financial year or have income beyond your salary, Form 122 is what keeps your tax calculation clean. Instead of your employer guessing or deducting extra tax, this form lets you declare everything in one place so your salary TDS is calculated correctly.
It replaces older forms like 12B and 12BAA. You now use a single format to report previous salary, other income, and any tax already deducted elsewhere.
When you actually need to submit this
You use this form only when your tax situation is not straightforward. For example, if you worked for more than one employer in the same year, have home loan interest causing a loss, or earned income like bank interest where TDS is already deducted.
If none of these apply and you have only one salary source, this form is usually not required.
What you are declaring in Form 122
You report salary from your previous employer, including tax already deducted. You also declare loss from house property if you are claiming home loan interest. In addition, you include other income like interest or rent where TDS or TCS has already been applied.
This helps your current employer adjust tax deductions instead of charging full tax again on the same income.
Details you should keep ready
You need previous employer details like TAN and salary breakup. Your earlier TDS figures usually come from Form 130 or salary slips. If you are claiming house property loss, you need a loan interest certificate from your bank.
For other income, keep TDS proof ready. This ensures you enter exact values and avoid mismatch during final tax filing.
Why submitting this matters
If you skip this form, your employer calculates tax only on current salary. That often leads to higher TDS deduction because previous tax credits are not considered. You then wait for a refund after filing your return.
Submitting Form 122 avoids that. Your tax gets balanced during the year itself.
If you are also managing TDS on interest income separately, you can use Form 121 to avoid unnecessary deductions where eligible.
Where to submit and how it is used
This form is not uploaded on the tax portal. You submit it directly to your employer or through your company payroll system. The employer uses it internally to compute monthly TDS.
This is an official form issued by the Income Tax Department of India. Always use the latest format to ensure your declaration is accepted by payroll systems without errors.
