Introduction

The Tax Deduction and Collection Account Number (TAN) is a unique identifier issued by the Income Tax Department of India to all individuals and entities responsible for deducting or collecting tax at source. TAN plays a crucial role in the proper reporting, payment, and reconciliation of Tax Deducted at Source (TDS) and Tax Collected at Source (TCS) transactions. Its correct usage ensures that the taxes deducted or collected are accurately credited to the government and linked to the right deductor and deductee. Quoting the wrong TAN—whether due to oversight, clerical error, or lack of awareness—can lead to serious legal, financial, and operational consequences that affect both the deductor and the payee.

Rejection of TDS/TCS Returns

One of the most immediate and direct consequences of quoting an incorrect TAN in TDS or TCS returns is the rejection of the return. The Income Tax Department’s electronic processing systems are designed to validate the TAN field before accepting any filing. If the quoted TAN does not match the records in the department’s centralized database, the return will be flagged as invalid or defective. This not only delays the submission process but may also trigger late filing penalties and interest on the delayed remittance of tax.

Non-Credit of TDS to Deductee

Another critical issue that arises from quoting the wrong TAN is the failure to credit the tax to the deductee’s account. When the Income Tax Department processes TDS returns, it matches the deducted tax with the deductee’s PAN and the deductor’s TAN. If the TAN is incorrect, the credit will not appear in the deductee’s Form 26AS, even though tax was actually deducted. As a result, the deductee may face difficulties during income tax return filing and may not be able to claim credit for the tax deducted, leading to higher tax liability or refund delays.

Issuance of Invalid TDS Certificates

Employers and businesses are required to issue TDS certificates such as Form 16 or Form 16A to employees or vendors. These certificates must carry the correct TAN of the deductor. If a wrong TAN is printed on these certificates, they become invalid in the eyes of the Income Tax Department. The deductee may be unable to use such a certificate to claim tax credit, and the deductor could be required to issue revised certificates, adding to administrative burdens and potential delays in compliance.

Disallowance of Expenses in Tax Assessment

The Income Tax Department may disallow the claimed business expenses if tax was deducted but not properly reported due to a wrong TAN. Under tax laws, the deduction of certain expenses—such as contractor fees, professional charges, and rent—is allowed only if TDS has been duly deducted and reported. Quoting the wrong TAN can cause the tax authorities to treat such deductions as unsubstantiated, thereby increasing the taxable income of the business and raising its overall tax liability.

Imposition of Penalties Under Section 272BB

The Income Tax Act imposes a monetary penalty under Section 272BB for failure to quote TAN correctly in TDS returns, challans, or certificates. If a person quotes an incorrect TAN or uses a TAN not allotted to them, the Assessing Officer can impose a penalty of ₹10,000. This penalty is separate from any interest or late filing fees and may be levied even if the mistake was unintentional. This provision underscores the legal importance of quoting the correct TAN in all TDS-related documents.

Difficulty in Filing Correction Statements

Correcting a wrongly quoted TAN requires the filing of a correction statement through the TRACES portal, which can be time-consuming and technically complex. The process may involve multiple validations, approvals, and digital signatures. Until the correction is processed, the deductor’s compliance status remains pending, and the deductee may continue to suffer from the absence of credited TDS in their tax records. This affects the overall compliance rating of the business and may draw further scrutiny from tax authorities.

Impact on Reputation and Business Relationships

From a practical standpoint, quoting the wrong TAN can damage a business’s reputation with employees, vendors, and government agencies. Vendors expect timely and accurate TDS credits, and employees rely on valid Form 16 for their tax filings. Errors in TAN can undermine confidence, delay transactions, and strain professional relationships. In competitive business environments where compliance is a key factor, such administrative lapses can lead to missed opportunities and damaged credibility.

Conclusion

Quoting the wrong TAN in TDS-related documents and filings can have a wide array of negative consequences, ranging from return rejections, tax credit mismatches, invalid certificates, and financial penalties to reputational damage and strained business relationships. Given its central role in tax compliance, TAN must be used with precision and care in every relevant transaction. Employers, accountants, and businesses must ensure that the correct TAN is quoted consistently across all tax filings and communications to avoid costly errors, uphold compliance, and maintain trust with stakeholders.
