CBDT Notifies Income-Tax Rules, 2026 Under Income-Tax Act, 2025

India’s Central Board of Direct Taxes notified the Income-tax Rules, 2026 on 20 March 2026, setting up a sweeping shift in forms, reporting and compliance procedures from 1 April 2026 under section 533 of the Income-tax Act, 2025.

The change recasts the daily machinery of the tax system, from PAN and TAN applications to TDS returns, remittance certificates and audit reports. CBDT’s transition material shows the framework has been cut from 511 rules with 399 forms under the older regime to 333 rules with 190 forms under the new one.

That reduction goes beyond renumbering. It reshapes how taxpayers, officers, employers, finance teams and non-residents will file statements, certificates and declarations during the first year of the new law.

CBDT has also released a Rules-mapping utility, a Forms-mapping utility, and a Forms FAQ and guidance page to help users compare the Income-tax Rules, 1962 with the Income-tax Rules, 2026. The move signals that the rules are central to the transition under the Income-tax Act, 2025, not a back-office adjustment.

For many taxpayers, the first visible effect will come through redesigned forms rather than rewritten legal obligations. Department guidance says the material is meant to help taxpayers navigate the new forms, while legal interpretation must come from the Income-tax Act, 2025 and the Income-tax Rules, 2026 themselves.

Across the new framework, four patterns stand out. Older multi-purpose forms have been split into category-specific forms, duplicative forms have been merged, reporting formats have been aligned with the new tax year and section numbering, and compliance design has moved toward more structured digital formats with cleaner validation and fewer repetitive fields.

PAN applications are among the clearest examples of that redesign. The older Form 49A and Form 49AA framework has been broken into Form 93 for Indian individuals, Form 94 for Indian companies or Indian entities, Form 95 for individuals who are not citizens of India, and Form 96 for entities incorporated or formed outside India.

That change aims to match forms more closely to the filer. Instead of one broad application carrying fields that do not apply to many users, the new structure separates taxpayers by category.

CBDT has applied the same logic to TAN. The old single Form 49B has been split into Form 134 for government entities and Form 135 for non-government entities, while a new form has been introduced for allotment of Accounts Office Identification Number, or AIN.

Pending PAN applications as of 31 March 2026 will continue without a fresh filing. CBDT’s FAQ says the start of the new Rules does not invalidate applications already in the system.

The most sensitive transition may come in TDS and TCS reporting during FY 2026–27. Deductors may need to file returns under both the old and new frameworks, depending on the quarter involved.

For Q4 of FY 2025–26 covering January to March 2026, the old framework remains in place. Returns in Forms 24Q, 26Q, 27Q, and 27EQ are due by 31 May 2026.

For Q1 of Tax Year 2026–27 covering April to June 2026, the new Rules take over. Form 138 replaces old 24Q for salary TDS, Form 140 replaces old 26Q for non-salary TDS, Form 144 replaces old 27Q for non-resident TDS, and Form 143 replaces old 27EQ for TCS.

The split creates a narrow but important compliance challenge. A company could be working with one set of forms for one quarter and a different set for the next, even within the same filing season.

Correction statements add another layer. CBDT’s FAQ says corrections for Q1 to Q4 of FY 2025–26 or earlier must still be filed under the old framework, rather than moving into the new system after 1 April 2026.

That makes the transition period-specific and, in some cases, event-specific. It also raises the chance of filing errors if payroll systems, ERP software and compliance calendars are not updated in time.

CBDT has warned that internal systems must reflect the new section numbering, terminology and reporting requirements under the Income-tax Act, 2025. For employers and finance teams, the risk lies less in tax policy than in using the wrong form for the wrong period.

The same timing rule applies to challan-cum-statement compliance. Under the old law, certain transactions were reported through Forms 26QB, 26QC, 26QD, and 26QE instead of regular quarterly TDS returns.

Those forms covered TDS on purchase of immovable property, rent by certain individuals or HUFs, specified payments by individuals or HUFs to contractors and professionals, and transfers of virtual digital assets. For transactions where the event of credit or payment occurred on or before 31 March 2026, those old forms will still govern the filing.

That point matters because it ties compliance to the date of the underlying event rather than the later date of tax deposit or portal interaction. A taxpayer filing after 1 April 2026 may still need to use the earlier form set if the triggering transaction happened before the cutoff.

Another visible simplification appears in declarations that were earlier made through Forms 15G and 15H. Under the old regime, those declarations were governed by section 197A, while the corresponding provision under the new law is section 393(6) of the 2025 Act.

From Tax Year 2026–27 onward, the relevant declaration shifts to Form 121 under the Income-tax Rules, 2026. CBDT says the eligibility criteria remain the same, but the new system combines the older 15G and 15H structure into a single form.

That merger addresses a long-running compliance problem. Under the earlier system, each payer had to generate separate UINs for each Form 15G or 15H even when the PAN and year were identical, creating duplication and reconciliation difficulties.

Salary-relief claims will also move to a more structured format. Old Form 10E gives way to Form 39 for relief in cases such as additional salary, gratuity, retrenchment compensation, and commutation of pension.

CBDT says Form 39 introduces auto-population of data, real-time validations, standardized input tools, and more structured computation tables. The department has described the redesign as a response to repeated-entry burdens and avoidable compliance errors under the earlier form.

The shift illustrates the wider approach behind the Income-tax Rules, 2026. The objective is not only to reorder form numbers but to standardize data capture and reduce filing inconsistencies in a system built around digital submission.

Audit reporting is another area where the architecture changes sharply. Old Forms 3CA, 3CB, and 3CD have effectively been brought together into Form 26 under the new regime.

CBDT’s Form 26 FAQ says it is the prescribed Report of Audit of Accounts and Statement of Particulars under section 63 of the 2025 Act read with Rule 47 of the 2026 Rules. It applies for tax years beginning on or after 1 April 2026.

The consolidated form still contains multiple parts, including components corresponding to the earlier 3CA and 3CB distinctions. Filing timelines remain linked to the due date for the return of income, preserving the audit-report function while reorganizing its format.

For professionals and larger businesses, that is one of the broadest compliance changes in the new rulebook. It replaces a fragmented audit form structure with a single integrated format under the Income-tax Act, 2025.

Non-resident remittances also move into a renumbered framework. Old Forms 15CA and 15CB, which were linked to section 195(6), now correspond to Forms 145 and 146 under section 397(3)(d) of the 2025 Act.

CBDT says Form 15CA and Form 15CB already submitted for remittances made before 31 March 2026 will remain valid, provided the remittance actually occurred within the date mentioned in the form. For remittances made on or after 1 April 2026, Forms 145 and 146 will apply.

For NRIs, foreign companies and residents making outbound remittances, the department’s guidance points to continuity in substance. Remitters must still furnish information about the remittance, obtain a Chartered Accountant certificate where required, and ensure TDS compliance.

That continuity runs through several parts of the transition. CBDT’s FAQs indicate that while forms and section references have changed, many underlying obligations have not.

The eligibility conditions behind the old 15G and 15H system continue under section 393(6), though the filing vehicle becomes Form 121. Remittance certification continues under new form numbers. Due dates for TDS deposit for non-government deductors also remain unchanged across the shift.

That makes the Income-tax Rules, 2026 a procedural overhaul more than a reinvention of every tax duty. In several places, the form architecture changes more than the entitlement, liability or filing deadline underneath it.

Taxpayers and officers will still need to watch the boundaries carefully. CBDT’s educational guidance and mapping tools can help users locate corresponding rules and forms, but the department has said the statutory text prevails for legal interpretation.

That warning carries weight during the first year of transition, when older quarters, correction statements and pre-1 April 2026 triggering events remain tied to the earlier framework. Users who assume everything migrates automatically into the new system risk filing against the wrong provision.

The first year will test internal discipline as much as legal understanding. Payroll teams, tax professionals, finance departments, chartered accountants and officers will need to track old-form obligations and new-form obligations side by side.

The broader picture, though, is clear. By cutting the number of rules and forms, splitting broad applications into narrower ones, merging overlapping declarations, and shifting toward data-validated digital filings, CBDT has made the Income-tax Rules, 2026 the working engine of the Income-tax Act, 2025. For taxpayers, officers and NRIs alike, compliance after 1 April 2026 will depend less on memorizing new numbers than on matching each filing to the right period, the right event and the right form.
