Salary tax · 3 MIN READ
Joining a new employer during the year and declaring previous salary through Form 122
A change of employer does not start a fresh tax year. If the new payroll forecast ignores salary already earned and tax already deducted elsewhere, the employee may receive an unrealistic take-home estimate and face a larger adjustment later.
For the relevant Income-tax Act, 2025 framework, Form 122 corresponds to earlier Forms 12B and 12BAA. The Department’s FAQ explains its use for relevant income and tax information, including income from more than one employer. [1]
Collect history separately from the current salary master
The new employer’s monthly salary rate tells payroll what the person may earn going forward. It does not show what they earned before joining. Keep prior-employer earnings and tax figures in a distinct opening tax record with a defined period.
Ask for the employee’s statement and relevant supporting documents through the authorised channel. Reconcile the employee identity, employer information, dates and totals. If the final previous-employer certificate is not yet available, document the approved provisional handling and the follow-up required.
Use Form 122 for its actual purpose
The Department describes Form 122 as beneficial rather than mandatory by law and says it is provided to the employer, including through an available HR or payroll system, rather than uploaded as that declaration to the income-tax portal. [1]
That does not make the underlying income disappear if the employee chooses not to provide information. Explain the limits of the employer’s forecast and the employee’s responsibility to handle the final tax position correctly.
Avoid duplicating annual benefits in the forecast
Payroll should not treat a new employment record as permission to grant a fresh full-year benefit without considering the complete annual calculation. Review prior income, deductions and the applicable regime using the proper tax-year rules.
For illustration, a person joins in October after earning salary from April to September elsewhere. A forecast using only October-to-March salary can understate the annual income. Simply adding the previous tax deduction without adding the associated income is also an incomplete working.
Keep credits and other information traceable
The form can include relevant non-salary information and tax credits within the applicable framework. Do not add a credit merely because an employee mentions a tax payment in a message. Obtain the details needed to map it to the correct person and period and review the permitted treatment.
Use an exception queue for missing evidence or inconsistent totals. Any later update should preserve the previous version, reason and effect on the salary-tax projection.
Explain a catch up deduction
If complete history arrives later, the projected annual liability and remaining deductions may change. Explain that adjustment with the income included, tax already recognised and periods remaining. It should not appear as an unexplained punishment for changing jobs.
The Department’s transition guidance also requires attention to the correct old or new tax framework for the relevant period. [2] Payroll Advisor can help organise the opening records and calculation within scope, so the first salary forecast is based on the employee’s actual year rather than a blank new-joiner screen.
