How to plan your 60-UDIN annual cap

ICAI directive: a Chartered Accountant can generate a maximum of 60 tax-audit UDINs per financial year. The cap is hard-coded into the UDIN portal; you can't exceed it even by request. Plan accordingly.

Why the cap exists

ICAI's view: a single CA can't meaningfully supervise more than 60 tax audits in a year (300 days of working time / 5 days per audit = 60). The cap forces firms to distribute the work across partners rather than load it onto one signature.

What counts towards the cap

• UDIN on Form 3CA + 3CD (tax audit) — counts.
• UDIN on Form 3CB + 3CD — counts.
• GST audit (Form 9C) UDIN — separate cap, no limit.
• Certifications (15CB, valuation, etc.) — separate cap, no limit.

Allocation strategy

If your firm has 3 partners and 200 tax-audit clients:

1. Front-load the 60 most complex audits with your most experienced partner; let them start in May/June so they finish before the September deadline.
2. Allocate the next 120 clients across 2 partners, 60 each. Keep them simple — repeat clients, clean books, low judgment-call rate.
3. The remaining 20+ clients: refer out to a partner firm or push the audits into the next FY (if Sec 44AB applicability becomes optional via presumptive scheme migration).

Risks of bumping against the cap late

• You hit 60 on 25 September; the remaining 5 clients miss the 30 September deadline.
• Penalty: 0.5% of turnover or ₹1,50,000 (whichever lower) per client. For a 50 cr turnover client, that's ₹1.5 lakh — recoverable from the firm.
• Reputation: those clients leave next year.
