A TDS Compliance Calendar That Actually Prevents Interest and Penalties
Most TDS defaults are calendar failures, not knowledge failures. A month-by-month operating rhythm for deduction, deposit, returns and certificates — built from running it inside a manufacturing company.
Table of contents
Ask any TDS officer what they see most, and it will not be exotic interpretation disputes. It will be late deposits, late returns and mismatched challans — failures of rhythm, not of law.
After running monthly TDS cycles for a manufacturing company (typically ₹8–12 lakh of monthly liability across 26Q and 24Q), I standardised the calendar below. Since adopting it, interest under Sections 201(1A) and late fees under 234E on our filings: zero.
The monthly rhythm
| Day of month | Action | Owner |
|---|---|---|
| 1st–3rd | Freeze prior-month ledgers; extract TDS-relevant expense and payment entries | Accounts |
| 4th | Section-wise summary (194C, 194J, 194I, 194Q, 192) reviewed against ledgers | Tax |
| 5th | Compute liability, verify PAN status and lower-deduction certificates | Tax |
| 6th | Challan prepared and approved | Manager |
| 7th | Deposit — statutory due date | Tax |
| 15th | Reconcile challan CIN against OLTAS / e-filing portal | Tax |
The trick is that deposit preparation starts on the 1st, not the 5th. Every default I have ever investigated traces back to starting late.
The quarterly layer
Returns and certificates ride on top of the monthly loop:
- Form 26Q / 24Q — due the last day of the month following the quarter (31 July for Q1, and so on).
- Form 16A — within 15 days of filing the return; calendar it as one task, not two.
- Q4 special case — 24Q needs Annexure II salary details; start collecting investment proofs in February, not May.
Three controls worth the effort
- PAN-verification gate. No vendor is paid the first invoice until PAN is verified on the portal. A wrong PAN means 20% deduction under Section 206AA and a guaranteed correction cycle later.
- A "new payment type" trigger. Any new expense head routes past the tax desk once — this is how you catch 194Q applicability, RCM interplay and perquisite issues before the first payment, not in the audit.
- Reconciliation before the return, not after. Matching books-to-challan on the 15th means the quarterly return is an assembly job, not an investigation.
The honest summary
Nothing here is clever. That is the point: TDS compliance rewards boring, early, owned processes and punishes heroics. Build the calendar once, assign names to rows, and the interest column of your tax ledger goes quiet.
This reflects my personal working method, not professional advice for any specific taxpayer.
