Date of Signing vs UDIN Generation: Which Date Counts for 60 Tax Audit Limit?
For the 60 tax audit limit, the real question is not when the UDIN is generated but which date the system treats as the audit trigger.

The 60 tax audit limit has become a key compliance issue for practising Chartered Accountants. With ICAI linking the ceiling to the UDIN system from 1 April 2026, CAs must track each tax audit assignment with care.
What is the 60 Tax Audit Limit?
A practising CA has a limit of 60 tax audit assignments per financial year. The limit applies to specific Section 44AB sub-categories:
Tax audit category | Counted for 60 limit |
Form 3CA under third proviso to Section 44AB | Yes |
Form 3CB under Section 44AB(a) | Yes |
Form 3CB under Section 44AB(b) | Yes |
Form 3CB Combined under Section 44AB | Yes |
Form 3CB under Section 44AB(c) | No |
Form 3CB under Section 44AB(d) | No |
Form 3CB under Section 44AB(e) | No |
The ceiling is member-wise. Assignments signed by a member in individual capacity or as a partner in multiple firms are aggregated toward the 60-audit limit.
Date of Signing is the Deciding Factor
For ceiling purposes, the assignment is counted based on the date of signing of the Tax Audit Report.
The UDIN generation date does not affect the financial year in which the assignment is counted. A gap between signing and UDIN generation does not shift the assignment to another financial year.
Example 1: Report Signed in March, UDIN Generated in April
A CA signs a tax audit report on 30 March 2027. UDIN is generated on 5 April 2027.
This assignment counts toward FY 2026-27. The UDIN date does not move it to FY 2027-28.
Example 2: Report Signed in April for Earlier Assessment Year
A tax audit report for a prior assessment year is signed on 10 April 2027, with UDIN generated the same day.
The assignment belongs to FY 2027-28, as the signing date determines the ceiling year. The assessment year in the report does not affect the count.
UDIN Generation Timeline Is a Separate Rule
UDIN must be generated at the time of signing. If not feasible, it must be generated within 60 days from signing.
This 60-day period ensures UDIN compliance but does not alter the tax audit ceiling computation.

| Issue | Relevant date |
| 60 tax audit ceiling | Date of signing |
| UDIN generation deadline | Within 60 days of signing |
| Financial year of count | Year in which report is signed |
| E-filing validation | UDIN must match portal parameters |
This Matters for CA Firms
The signing-date rule impacts practice management. Firms must check the available limit before signing reports.
For instance, a partner has already signed 60 counted tax audit reports in FY 2026-27. If the partner signs another counted report on 31 March 2027 and generates UDIN in April, the assignment still counts in FY 2026-27, exceeding the limit.
Firms must maintain a tracker with:
- Client name and PAN
- Assessment year
- Form type
- Section 44AB sub-category
- Date of signing
- UDIN generation date
- Signing partner
- Whether the assignment counts toward the ceiling
Tracking only UDIN generation dates can lead to incorrect ceiling positions.
Common Mistakes to Avoid
Treating UDIN Date as the Count Date
This is the biggest error. UDIN generation date is relevant for UDIN compliance. It is not the date for the 60 tax audit ceiling.
Checking the Limit After Signing
The limit must be checked before signing. Once the report is signed, the assignment enters the count for that financial year.
Assuming Each Firm Gives a Separate Limit
The limit is member-wise. A CA signing in different firms does not get separate limits for each firm.
Ignoring the Correct 44AB Category
Only specified sub-categories count toward the 60 limit. CAs must check the category before signing.
Entering an Incorrect Signing Date
The signing date entered in the UDIN portal must match the actual signing date. A mismatch creates compliance risk and disciplinary exposure.
Impact on Taxpayers
Taxpayers must also understand the issue. A tax audit report is not just a filing formality. If the report, UDIN or portal validation fails, the taxpayer faces compliance issues.
A defective or invalid audit report creates risk under the Income-tax Act. Delay in furnishing the tax audit report also attracts exposure under Section 271B.
Small business owners, freelancers, and professionals subject to tax audit must give books, statements, confirmations, and GST details to the CA in time. Last-minute filing increases the chance of errors.
Key Takeaway
The 60tax audit ceiling depends strictly on the signing date of the Tax Audit Report. UDIN generation does not change the assignment year.
CAs must verify the available limit before signing. Firms must track assignments based on signing dates. Taxpayers must cooperate to avoid delays and compliance risk.
