Section 206CA and Section 206CB of Income Tax Act: TAN and Processing of TCS Statements
Sections 206CA and 206CB formed part of the tax collection at source framework under the Income-tax Act, 1961. Section 206CA dealt historically with the tax collection account number, while Section 206CB provided the mechanism for processing statements of tax collected at source. These provisions should now be read with the transition to the Income-tax Act, 2025 for transactions and tax years governed by the new law.
Meaning of TAN
TAN means Tax Deduction and Collection Account Number. It is a 10-digit alphanumeric identification number issued by the Income Tax Department to persons responsible for deducting tax at source or collecting tax at source. TAN is generally required to be quoted in TDS and TCS statements, payment challans, certificates and prescribed communications.

Section 206CA of the Income-tax Act, 1961: Tax Collection Account Number
Section 206CA originally required every person collecting tax in accordance with Section 206C to apply, within the prescribed time, for allotment of a tax collection account number. Once allotted, the number was required to be quoted in specified TCS-related documents.
Documents in which the number was required to be quoted
- Challans for payment of sums collected under the TCS provisions.
- Certificates furnished in respect of tax collected at source.
- Returns delivered to the income-tax authority under the applicable TCS provisions.
- Other prescribed documents relating to TCS transactions.
The provision itself stated that Section 206CA would not apply on or after 1 October 2004. TAN requirements subsequently operated through the wider statutory framework governing both tax deduction and tax collection account numbers.
Section 206CB of the Income-tax Act, 1961: Processing of TCS Statements
Section 206CB prescribed the procedure for processing a statement of tax collected at source, including a correction statement, furnished by a collector under Section 206C. Its purpose was to permit automated or centralised determination of the amount payable by, or refundable to, the collector after specified adjustments.
Adjustments while processing a TCS statement
Under Section 206CB, the sums collectible could be computed after adjustment for an arithmetical error in the statement and an incorrect claim apparent from information contained in the statement. Interest and the applicable fee could then be computed, and payments already made could be adjusted to determine the final amount payable or refundable.
| Processing step | Purpose |
|---|---|
| Arithmetic adjustment | Corrects an arithmetical error appearing in the TCS statement. |
| Apparent incorrect claim | Adjusts a claim that is inconsistent with another entry or applies an incorrect TCS rate apparent from the statement. |
| Interest computation | Computes applicable interest on the basis prescribed by law. |
| Fee computation | Accounts for the applicable fee for default in furnishing statements. |
| Payment adjustment | Gives credit for relevant tax, interest and fee already paid. |
| Intimation and refund | Determines and communicates the amount payable or refundable and enables grant of the refund due. |
Under the 1961 Act provision, an intimation under Section 206CB(1) could not be sent after the expiry of one year from the end of the financial year in which the statement was filed. The Central Board of Direct Taxes was also empowered to frame a scheme for centralised processing of TCS statements.
What was an "incorrect claim apparent from any information in the statement"?
For Section 206CB, the expression covered a claim based on an entry in the statement that was inconsistent with another entry of the same or another item in that statement, or a claim involving a rate of collection of tax at source that was not in accordance with the Act.
Income-tax Act, 2025 and the transition from the 1961 Act
The Income-tax Act, 2025 replaced the Income-tax Act, 1961 from 1 April 2026. Matters relating to periods before Tax Year 2026-27 may nevertheless continue to be governed by the 1961 Act under the repeal and savings framework. Therefore, Section 206CB can remain relevant to statements, proceedings, demands, refunds and other matters pertaining to periods governed by the old Act.
For Tax Year 2026-27 onwards, taxpayers and collectors should refer to the corresponding provisions, rules, forms and procedures under the Income-tax Act, 2025 and the Income-tax Rules, 2026. The official Income Tax e-Filing Portal provides current filing, payment, TAN and compliance services.
Practical points for TCS collectors
- Use the law applicable to the relevant transaction and period; do not assume that a 1961 Act section number applies to a Tax Year beginning on or after 1 April 2026.
- Existing TAN numbers remain valid under the new regime.
- Quote TAN wherever required in TDS/TCS statements, challans, certificates and prescribed communications.
- Verify TCS statements carefully before filing because arithmetic errors, inconsistent entries and incorrect rates may affect processing.
- Use correction facilities where permitted if a filed statement contains an error.
- For older periods, retain records necessary to respond to processing intimations, demands, refunds or correction requirements under the saved provisions of the 1961 Act.
