The Income-tax Act, 2025 has introduced a major structural reform in the salary TDS mechanism through Form 122. Though appearing to be a simple replacement of the earlier Forms 12B and 12BAA, the new framework substantially expands the scope of employee income reporting and payroll tax compliance.
Form 122 has been prescribed under Section 392(4)(a) of the Income-tax Act, 2025 read with Rule 204 of the Income-tax Rules, 2026. The form is designed to provide a consolidated declaration mechanism enabling employees to furnish details of multiple income streams, tax deductions, and losses so that employers may compute correct TDS liability during the financial year itself.
Under the earlier regime, salaried employees changing jobs during the year generally submitted Form 12B to disclose salary from the previous employer, while Form 12BAA was separately used for reporting other income and TDS/TCS details. The new law merges both reporting obligations into a single integrated compliance document — Form 122.
The objective behind introducing Form 122 is clear:
to ensure accurate salary TDS deduction at the payroll stage itself instead of leaving reconciliation to the income-tax return filing stage.
The form permits reporting of:
- salary from previous or simultaneous employers,
- taxable perquisites and allowances,
- house property loss,
- other taxable income,
- TDS already deducted elsewhere, and
- TCS credits available during the year.
One of the biggest practical problems under the old regime was excess TDS deduction due to fragmented income reporting. Employees frequently suffered unnecessary tax deduction where the employer was unaware of prior salary income, home loan losses, or TDS already deducted on fixed deposits and investments. This resulted in large refund claims at the time of filing the return.
Form 122 attempts to resolve this inefficiency by creating a unified tax declaration architecture.
The form assumes special importance in cases involving:
- job changes during the year,
- dual employment situations,
- employees having rental income or home loan interest loss,
- high-value FD interest income,
- professionals shifting from consultancy to employment, and
- employees having substantial TDS/TCS credits outside salary.
The structure of Form 122 broadly contains three major components:
Part A — Employee Particulars
This section captures basic details such as:
- name,
- PAN,
- address,
- residential status, and
- relevant tax year.
Part B — Salary from Other Employers
This part requires disclosure of:
- salary received from previous or simultaneous employers,
- taxable allowances,
- perquisites,
- provident fund accretions, and
- TDS already deducted by such employer(s).
Part C — Other Income and Tax Credits
This portion enables reporting of:
- loss from house property,
- income from other sources,
- TDS on non-salary income, and
- TCS collected during the year.
However, it is important to note that while positive income from other heads can be reported, losses other than house property loss are generally not intended to be adjusted through payroll TDS computation.
From an employer’s perspective, Form 122 significantly enhances payroll compliance responsibility. Once the declaration is furnished, the employer becomes obligated to consider such information while computing TDS under Section 392(1). Failure to appropriately consider disclosed information may lead to payroll mismatches, excess deduction disputes, and employee grievances.
At the same time, the form also increases accountability of employees. Any incorrect declaration, suppression of income, or false reporting may expose the employee to tax demand, interest, and potential penalty consequences during assessment proceedings.
Another important practical implication is the likely reduction in refund-driven return filings. By enabling correct TDS adjustment during the year itself, the Government appears to be moving toward a more real-time tax collection framework where salary taxes are aligned closer to final tax liability itself.
Form 122 also reflects a broader legislative trend under the Income-tax Act, 2025 — consolidation and simplification of forms and compliance structures. Several older forms have now been merged, renumbered, or structurally redesigned under the new Act.
In practical payroll administration, Form 122 may gradually become one of the most important annual declarations for salaried taxpayers, particularly in metro cities where job mobility and multiple income streams are increasingly common.
For Chartered Accountants, HR professionals, payroll consultants, and tax deductors, understanding Form 122 is now essential because salary TDS computation under the new regime is no longer restricted merely to employer-paid salary. The payroll system is increasingly evolving into an integrated tax reporting mechanism.
In substance, Form 122 represents a shift from isolated salary taxation to consolidated employee-level tax visibility.
The era of “one employer, one salary, one TDS computation” is steadily being replaced by “one employee, one integrated tax declaration.”
