If you changed your job during the year or earn money from more than one source, you need to inform your employer properly for the correct tax deduction.
Under the new Income Tax Act, 2025, this is done using Form 122. It helps your employer understand your total income—including salary from your previous job—so they can deduct the right amount of tax (TDS).
If you don’t submit this form, your employer might deduct less or more tax, which can cause problems later like paying extra tax or waiting for refunds.
What has changed? Earlier, you were required to submit two separate forms—12B and 12BAA. Now from tax year 2026-27 onwards, everything is combined into one single form, Form 122, making the process simpler.
What is Form 122 and why was it introduced?
Form 122 is a new declaration form that a salaried employee submits to their employer. It contains details of income earned from other sources or previous employers during the same tax year. In simple terms, your employer uses this form to see your complete financial picture, not just the salary they are paying you.
It covers details like:
- Salary from previous employer
- House property loss (like home loan interest)
- Other income (interest, etc.)
- TDS/TCS already deducted elsewhere
This form is introduced under Section 392(4)(a) of the Income Tax Act, 2025, replacing older mechanisms. The idea is simple: Instead of calculating tax in parts, everything is considered together so that the correct TDS is deducted from your salary.
Who should submit Form 122?
Not every employee needs to submit this form. It is mainly meant for those whose income is not coming from just one source. You should submit Form 122 if:
- You changed jobs during the same financial year
- You worked with more than one employer
- You have income apart from salary (like interest income)
- You want to claim loss from house property (home loan interest)
- TDS/TCS has already been deducted on other income
This form is only for salaried employees. Non-salaried individuals cannot use it. In simple terms, if your income is not straightforward, this form becomes useful.
What is the purpose of Form 122?
The main goal of Form 122 is to ensure that your employer deducts the correct amount of tax (TDS) from your salary. Let’s break down how it helps:
- Adjusts tax already deducted on other income
- Prevents excess tax deduction from salary
- Reduces chances of claiming refunds later
- Makes tax calculation smoother for both employee and employer
Now think practically. If you don’t inform your employer about other income, they will calculate tax only on your salary. This may result in wrong tax deductions, either too high or too low. Form 122 solves this problem by bringing everything into one place.
Is Form 122 mandatory?
No, it is not legally mandatory to submit Form 122. However, it is highly beneficial. If you don’t submit it:
- Your employer may deduct excess tax (TDS)
- You may have to claim refund while filing ITR
- Your cash flow gets affected during the year
So, while optional, it is practically very important.
When should you submit Form 122?
There is no strict deadline defined in law. However, it is expected that you submit it as early as possible in the financial year.
Ideally:
- Submit after joining a new employer
- Latest by 31st March of the financial year
The earlier you submit, the better your TDS calculation will be.
What details are required in Form 122?
Form 122 is divided into three main parts. Each part captures a different type of information.
Part A – Basic Employee Details
This section includes:
- Name
- Address
- PAN
- Residential status
- Tax year
This is basic identification information.
Part B – Salary from Other Employers
This part captures details of salary earned from previous or other employers. It includes:
- Name, PAN, TAN of employer
- Employment period
- Salary amount
- Taxable allowances
- Perquisites (benefits like car, accommodation)
- Provident fund contributions
- TDS deducted
This section ensures your total salary income is correctly calculated.
Part C – Other Income & Tax Details
This part includes:
- Loss from house property (like home loan interest)
- Other income (interest, etc.)
- TDS/TCS already deducted
This is important because it adjusts your overall tax liability.
Annexure – Perquisites Details
Here, you report benefits provided by your employer such as:
- Rent-free accommodation
- Car facility
- Domestic help paid by employer
- Travel benefits
- Utilities like electricity or water
- Excess PF contribution
- Interest on PF above limits
These are added because many employees forget that such benefits are also taxable.
Can Form 122 be submitted online?
Form 122 is not required to be uploaded on the Income Tax portal. You can submit it:
- Offline (physical form)
- Through your company’s HR or payroll system
So practically, you only need to give it to your employer.
Do you need to attach Form 122 with your ITR?
No, Form 122 is not required to be attached with your Income Tax Return (ITR). However, it plays an important role behind the scenes. It helps ensure that:
- Your Form 16 is accurate
- Your TDS is correctly deducted
- Your ITR filing becomes smoother
What is the difference between old forms and Form 122?
Earlier, employees had to deal with multiple forms like Form 12B and Form 12BAA. Now, these have been merged into a single form. Here’s the key change:
- Old forms: 12B & 12BAA
- New form: 122
Other updates include:
- New sections as per Income Tax Act, 2025
- Standardized employee details
- “Financial Year” replaced with “Tax Year”
This change reduces confusion and simplifies compliance for employees.
Conclusion
Form 122 is a practical tool designed to make tax deduction more accurate for salaried employees. If your income comes from multiple sources or you have changed jobs, this form helps your employer calculate the correct TDS. It reduces excess tax deduction, avoids refund delays, and keeps your tax filing smooth.
While not mandatory, using Form 122 is a smart step toward better tax management and fewer surprises at the time of filing your return.
