RegInfra converts Indian laws into machine-executable logic. Every compliance decision is made fresh at transaction time, with complete legal reasoning stored permanently.
The problem
When IT department raises a Section 201 demand notice — what does your team show them? Most teams cannot answer this question. That is what notices exploit.
Proves the deduction happened. Does not explain why 2% and not 1%, whether the threshold had crossed, or what PAN status was on that exact date.
Every decision behind the rate. Stored at calculation time. Immutable. Pull any transaction, any date — the answer is already there.
The gap in detail
| Data point | SAP / Oracle / Tally | RegInfra | Why it matters |
|---|---|---|---|
| Basics — both systems store these | |||
| TDS amount deducted | ✓ | ✓ | — |
| Section applied | ✓ | ✓ with ITA 2025 ref | — |
| What IT department actually asks | |||
Why this section over another? 194C vs 194J selection logic |
✗ No logic trail |
✓ Selection criteria stored |
Most common TDS dispute. 1% vs 10%. |
YTD at exact payment time? Cumulative threshold snapshot |
✗ Only current balance |
✓ Snapshot at moment of payment |
Threshold crossing must be provable retrospectively |
PAN status at payment date? Historical, not today's |
✗ Reads current PAN |
✓ Recorded as-of calculation time |
PAN status changes — evidence must be contemporaneous |
Rule version at calculation time? Which Finance Act was active |
✗ Cannot prove this |
✓ Cryptographic fingerprint |
Proof of rates active on that specific date |
Wrong section blocked before payment? Pre-transaction validation |
✗ | ✓ 400 error Hard block before money moves |
Silent wrong deductions compound for months |
How it works
Your payment system calls RegInfra before releasing funds. Pass the payment amount, vendor PAN, deductee type, and nature of payment.
RegInfra returns the correct section, rate, and amount — with the complete decision chain. Why that section. Why that rate. Threshold state at this exact payment. PAN status today.
Every decision is stored against the transaction. Query any payment by vendor PAN, date range, or section. When IT department raises a notice — the reasoning is already there. No reconstruction.
Every response includes the correct 393-series section reference. Not retrofitted from the old 194-series. Built for the new Act from the start, effective 1 April 2026.
Right fit
New contractors onboarded constantly. Payment nature varies per contractor. Engineering team maintaining TDS logic in codebase. Classification errors caught only when contractors complain.
TDS accuracy is product quality for you. Wrong deduction in your platform is your reputation problem. You need TDS logic as an API — so every Act change is RegInfra's problem, not yours.
Beyond TDS
New regulation = new rule files. No engine rewrite. The same machine-readable law pattern extends across India's complete regulatory stack.
