November 2026 is an important month for taxpayers, businesses, employers and professionals responsible for tax compliance. Several income tax-related deadlines fall during the month, covering TDS and TCS payments, issuance of tax certificates and income tax return filing for taxpayers whose accounts are subject to audit.

Missing these deadlines could lead to interest, late fees or penalties, depending on the nature of the default. Therefore, taxpayers and businesses should keep track of the applicable dates and complete their compliance requirements in advance.

Here is a look at the important tax-related deadlines falling in November 2026.

November 7: Deadline for TDS and TCS Payment for October

The first major compliance deadline in November is November 7, 2026.

Businesses, organisations and other persons responsible for deducting Tax Deducted at Source (TDS) or collecting Tax Collected at Source (TCS) must deposit the tax collected during October 2026 with the Central Government by this date.

This requirement applies to eligible deductors and collectors under the applicable income tax provisions.

Additionally, certain declarations in Form 127 under the Income Tax Rules, 2026, are required to be uploaded by this date. The form relates to prescribed situations in which a buyer submits a declaration to the seller for non-deduction of TDS, subject to the applicable conditions.

November 14: Issue TDS Certificates in Form 132

November 14 is another important date for taxpayers and entities responsible for deducting TDS.

Under the Income Tax Act, 2025, deductors are required to issue Form 132 for specified transactions involving tax deducted during September 2026.

These transactions may include:

• Rent payments.

• Transfer of immovable property.

• Payments for technical services.

• Transfer of virtual digital assets (VDAs).

The certificate provides details of the tax deducted and helps the recipient maintain records of their tax credits.

The applicable deadline is linked to the prescribed timeline for filing the relevant challan-cum-statement in Form 141.

November 15: Important TDS and TCS Certificate Deadlines

November 15 brings multiple compliance requirements for deductors, collectors and government offices.

The key forms and their purposes are as follows:

Form 131: TDS Certificate

Deductors must issue Form 131 for TDS other than salary, pension or specified senior-citizen interest income for the quarter ended September 30, 2026. The certificate helps taxpayers verify the tax deducted from their income.

Form 133: TCS Certificate

Tax collectors must issue Form 133 for tax collected at source during the quarter ended September 30, 2026. It provides details of the TCS collected and helps taxpayers reconcile their tax records.

Form 137: Statement by Government Offices

Government offices that deposited TDS or TCS for October without submitting a challan are required to furnish the prescribed statement by November 15.

These certificates and statements are important for maintaining accurate tax records and ensuring that tax credits are properly reflected.

November 21: ITR Filing Deadline for Audit Cases

November 21, 2026, is a crucial deadline for businesses and taxpayers whose accounts are subject to audit.

The income tax return filing deadline for eligible audit cases for Assessment Year (AY) 2026-27 has been extended from October 31 to November 21, 2026.

Taxpayers covered by this requirement were required to submit their tax audit reports by October 21, 2026.

Businesses and professionals falling under the audit provisions should ensure that their financial statements, audit reports and supporting documents are complete before filing their returns.

November 30: Transfer Pricing Returns and Form 141

November 30 is another significant deadline, particularly for taxpayers involved in international or specified domestic transactions.

Taxpayers required to furnish a report under Section 92E of the Income Tax Act, 1961, must file their ITR for AY 2026-27 by this date. These provisions generally apply to taxpayers undertaking transactions covered by transfer pricing regulations.

Additionally, Form 141 must be filed by November 30 for certain TDS deductions made during October 2026.

This form is a combined challan-cum-statement used to report specified TDS transactions, including:

• Payments involving the transfer of immovable property.

• Rent payments covered by the applicable provisions.

• Payments made by individuals or Hindu Undivided Families (HUFs) to contractors or professionals.

• Transfer of virtual digital assets.

Taxpayers and deductors should check the relevant provisions to determine whether this filing requirement applies to them.

What Happens If You Miss These Tax Deadlines?

Missing an income tax compliance deadline can create financial and administrative difficulties.

Depending on the applicable provision and the nature of the default, taxpayers may face interest, late filing fees or penalties. Delayed issuance of TDS certificates can also create problems for recipients when reconciling their tax credits with Form 26AS and other tax records.

For businesses, repeated compliance delays may also increase the burden of maintaining accurate financial and tax documentation.

How to Prepare for November's Tax Compliance Schedule

To avoid last-minute complications, businesses, employers and tax professionals should prepare a compliance calendar covering all applicable November deadlines.

Keep the following points in mind:

• Reconcile TDS and TCS deductions with payment records.

• Deposit October's TDS and TCS within the prescribed time.

• Prepare and issue the applicable TDS and TCS certificates.

• Complete pending tax audit and ITR-related formalities.

• Check whether transfer pricing provisions apply to your transactions.

• Verify the correct forms and deadlines under the applicable income tax rules.

Most importantly, taxpayers should carefully distinguish between forms and provisions under the earlier income tax framework and those applicable under the newer law.

Keeping track of these dates can help businesses and taxpayers avoid unnecessary penalties, maintain accurate records and complete their tax obligations without last-minute stress.
