TDS Software | Section 197 LDC

Section 197 LDCs honoured at the line, within the validity window.

Vendors with a lower-deduction certificate have section, rate and validity loaded at the vendor master. Bills posted within the window deduct at the lower rate. Bills posted outside the window deduct at the section default. Auto-expiry handles the cut-over.

Section 197 LDC FAQ

What buyers ask.

Bills posted before the LDC effective date. Lower rate or default?

Default. The LDC applies prospectively from the certificate effective date. Bills posted before that retain their original deduction. Retrospective application is not standard and requires manual override.

LDC for a specific section only. What if the vendor has bills under multiple sections?

The LDC applies only to the section it covers. If the vendor has 194J and 194I bills and the LDC is for 194J only, only 194J deductions use the lower rate. 194I uses the section default.

LDC renewal. How is it tracked?

The system tracks LDC expiry dates per vendor. 30 days before expiry, a vendor portal task and email nudge fire. Vendors upload the renewed certificate; the system updates rate and dates seamlessly.
