TAN Registration and TDS Return Filing: Complete 2026 Guide

TAN Registration and TDS Return Filing: Complete 2026 Guide

Every business, professional, or organisation that deducts tax at source before paying salaries, contractor bills, rent, or professional fees needs a Tax Deduction and Collection Account Number, commonly called TAN. Without it, you legally cannot deposit TDS with the government or file the periodic returns that report those deductions.

This guide walks through what TAN is, who is required to obtain one, the exact application process using Form 49B, and everything involved in filing quarterly TDS returns — from choosing the right form to avoiding the penalties that catch most first-time deductors off guard.

What is TAN and Why It Matters

TAN is a ten-character alphanumeric code issued by the Income Tax Department under Section 203A of the Income Tax Act, 1961. It typically follows a pattern of four letters, five numbers, and one letter (for example, DELM12345K), where the first three letters denote the jurisdiction and the fourth is usually the initial of the deductor's name.

TAN is distinct from PAN. PAN identifies a taxpayer for income tax purposes; TAN identifies an entity in its capacity as a deductor or collector of tax. Every challan used to deposit TDS/TCS, every TDS certificate issued to a deductee, and every quarterly return filed with the tax department must quote TAN. Quoting an incorrect or missing TAN can lead to the deposited tax not being credited to the deductee's account, causing disputes and compliance headaches down the line.

Who Needs to Apply for TAN

TAN is mandatory for any person or entity responsible for deducting or collecting tax at source. In practice, this includes:

• Companies (private limited, public limited, OPC) making payments of salary, professional fees, rent, contractor payments, or interest above prescribed thresholds
• LLPs and partnership firms with similar payment obligations
• Proprietorships that are subject to tax audit in the preceding financial year and make specified payments
• Trusts, societies, and NGOs paying salaries or professional fees
• Government offices and departments
• Individuals who are required to deduct TDS on property purchases above the prescribed value (though this specific transaction is generally handled via Form 26QB without a fresh TAN in many cases), or under other specified sections

If you are starting a company or LLP, TAN is typically one of the very first registrations you obtain, often applied for immediately after incorporation, since payroll and vendor payments begin almost immediately. Many businesses choose to apply for TAN alongside PAN through the integrated incorporation forms (such as SPICe+) rather than as a separate application, which saves considerable time.

How to Apply for TAN: Form 49B Process

TAN is obtained by filing Form 49B, prescribed under the Income Tax Rules. Here is the step-by-step process:

1. Determine your application route. If you are incorporating a new company or LLP, TAN allotment is usually bundled into the incorporation form itself, so a separate Form 49B is not required. For existing entities that never applied, or for proprietorships and other deductors, a standalone Form 49B application is filed.

1. Fill Form 49B online. The form is available through the authorised TIN facilitation portal (currently managed under the Protean/NSDL framework, though the exact portal branding has changed over the years and may change again). You will need to provide the legal name of the deductor, category (company, firm, individual, trust, etc.), registered address, details of the responsible person, and the relevant Assessing Officer (AO) code, which can usually be looked up on the same portal.

1. Pay the applicable fee. A modest processing fee (generally in the range of a few hundred rupees, inclusive of applicable taxes) is payable online at the time of submission. This fee is revised periodically, so always confirm the current amount on the portal before paying.

1. Submit and generate acknowledgment. Once submitted, an acknowledgment number is generated. For entities without digital signature-based verification, a signed physical acknowledgment along with supporting documents may need to be couriered to the processing centre, though most applications today are handled through paperless, Aadhaar-based, or e-sign verification.

1. Track and receive TAN. Processing typically takes a small number of working days once the application is verified as complete. The TAN is communicated via email and can also be verified on the income tax e-filing portal.

Documents typically required:

• Proof of identity and address of the applicant entity (incorporation certificate, partnership deed, or registration certificate as applicable)
• PAN of the entity (recommended, though TAN application itself does not always mandate PAN linkage at submission)
• Details of the principal officer or authorised signatory
• Proof of the registered office address

Filing TDS Returns: 24Q, 26Q, 27Q, and 27EQ

Once TAN is allotted and TDS deductions begin, the deductor must file quarterly statements summarising every deduction made. The form used depends on the nature of the payment:

• Form 24Q — for TDS deducted from salary payments to employees under Section 192. Filed by every employer with employees whose income crosses the taxable threshold or from whom tax has been deducted.
• Form 26Q — for TDS deducted on all payments other than salary made to residents, such as professional fees, contractor payments, rent, interest, and commission, typically under sections like 194C, 194J, 194H, 194I, and others.
• Form 27Q — for TDS deducted on payments made to non-residents and foreign companies, other than salary, generally under Section 195 and related provisions.
• Form 27EQ — for Tax Collected at Source (TCS), applicable to businesses required to collect tax at source on specified sales such as scrap, minerals, or high-value goods.

Each of these is filed quarterly, and each requires the deductor to report the PAN of every deductee, the amount paid, the tax deducted, and the challan through which the tax was deposited. Accuracy here is critical because any mismatch prevents the deductee from claiming credit in their own income tax return.

Step-by-Step Filing Process

1. Deduct and deposit TDS monthly. Tax deducted during a calendar month must be deposited with the government, generally by the 7th of the following month (with a relaxed timeline for March deductions).
2. Prepare the quarterly statement. Use the official return preparation utility (RPU) or authorised third-party software to compile deductee-wise details, challan details, and deduction particulars for the quarter.
3. Validate using the File Validation Utility (FVU). This checks the statement for structural and data errors before submission.
4. Upload the return. Returns are filed electronically through the income tax e-filing portal or authorised TIN-facilitation centres, using a valid digital signature or electronic verification code where applicable.
5. Generate Form 16 / Form 16A. After the return is processed, TDS certificates are generated and must be issued to the deductees — Form 16 for salaried employees (issued annually) and Form 16A for non-salary deductions (issued quarterly).

Fees Involved (2026, Indicative)

• TAN application fee: a modest government fee of roughly a few hundred rupees, subject to revision; professional/service fees for assistance typically range from a small fixed amount upward depending on the provider.
• TDS return filing: there is generally no separate government fee for filing the quarterly statement itself, but professional charges for preparation and filing (per quarter, per form) vary depending on the volume of deductee entries and complexity.
• Digital signature / e-verification costs, where applicable, are usually a modest one-time or annual expense.

Because government fee structures are revised from time to time, always confirm current figures before making payment, and consider working with a professional who tracks these updates.

Due Dates and Timeline (2026)

TDS payment and return filing follow a consistent quarterly cadence, though exact calendar dates should always be reconfirmed each year since the tax department occasionally issues extensions:

• Monthly TDS deposit: generally by the 7th of the following month; for deductions in March, the deposit deadline is typically extended to the end of April.
• Quarterly return filing (24Q/26Q/27Q/27EQ):

- Quarter 1 (April–June): due on or around July 31

- Quarter 2 (July–September): due on or around October 31

- Quarter 3 (October–December): due on or around January 31

- Quarter 4 (January–March): due on or around May 31

• Form 16 (salary TDS certificate): typically issued annually by mid-June following the end of the financial year.
• Form 16A (non-salary TDS certificate): issued quarterly, generally within about 15 days of the due date for filing the corresponding return.

These dates are indicative and consistent with the government's usual pattern; always cross-check the notified due dates for the specific financial year before filing, as extensions and rule changes do occur.

Penalties and Common Pitfalls

Non-compliance with TDS obligations attracts multiple layers of consequences, and businesses frequently underestimate how quickly these can add up:

• Late filing fee under Section 234E: a daily fee (commonly cited around ₹200 per day) is levied for each day of delay in filing the TDS return, until it equals the amount of tax deductible, whichever is lower — but note this accrues continuously and is not capped low.
• Penalty under Section 271H: in addition to the late fee, a discretionary penalty (which can range from a minimum to a substantially higher amount per return) may be imposed for filing an incorrect return or failing to file within the extended period, though relief is generally available if the tax, interest, and fee are paid and the return is filed within a reasonable time frame.
• Interest on late deduction or late deposit: interest accrues monthly (or part thereof) at rates that are typically higher for late deposit than for late deduction, compounding the cost of delay.
• Disallowance of expense: under Section 40(a)(ia), failure to deduct or deposit TDS on specified expenses can result in a portion of that expense being disallowed while computing business income, directly increasing taxable profit.
• Common pitfalls: using the wrong TDS section code, quoting an incorrect PAN for the deductee (which blocks their credit), missing the distinction between resident and non-resident payments, forgetting to file a "NIL" statement declaration where required, and not reconciling challan details with the return before submission.

Given the interlocking nature of these penalties, businesses are well advised to build TDS compliance into their monthly accounting cycle rather than treating it as a quarterly afterthought.

FAQ

Is TAN mandatory for every small business?

Not every business needs TAN immediately — only those responsible for deducting or collecting tax at source. However, once a business starts paying salaries above the taxable threshold, professional fees, or rent that attracts TDS, obtaining TAN becomes mandatory before the first deduction is made.

Can I use PAN instead of TAN for TDS compliance?

No. PAN and TAN serve different purposes. PAN identifies the taxpayer, while TAN specifically identifies the deductor for TDS/TCS transactions. Certain specific transactions, such as TDS on purchase of immovable property from a resident seller under Section 194-IA, are exceptions where the buyer's PAN is used instead of a fresh TAN.

What happens if I file a NIL TDS return?

If no tax was deducted during a particular quarter, deductors are generally expected to file a declaration of non-filing (NIL statement) on the e-filing portal rather than simply skipping the return, to avoid automated notices for non-filing.

How long does it take to get a TAN?

When applied for as part of company or LLP incorporation, TAN is typically issued within roughly the same short window as PAN, often within a few days of incorporation approval. Standalone Form 49B applications usually take a similarly short processing period once documents are verified.

Can TDS returns be revised after filing?

Yes. If errors are discovered — such as an incorrect challan or PAN mismatch — a correction statement can be filed to rectify the original return. It is advisable to reconcile the return against Form 26AS or the TRACES portal periodically to catch such errors early.

What is the difference between Form 16 and Form 16A?

Form 16 is the annual TDS certificate issued to salaried employees, summarising total salary paid and tax deducted through the year. Form 16A is issued quarterly for all non-salary TDS deductions, such as professional fees, rent, and contractor payments.

Does a proprietorship need TAN?

A proprietorship needs TAN if it is liable for tax audit in the preceding financial year and makes payments (salary, rent, professional fees, etc.) that attract TDS provisions. Small proprietorships below the audit threshold generally do not need to deduct TDS or obtain TAN.

What if TDS is deducted but not deposited on time?

Interest is charged for the delay, and if the case is serious or prolonged, it can even be treated as an offence under the Income Tax Act in extreme situations. Timely deposit, even if the return is filed slightly later, significantly limits the financial exposure.
