# #9552 [Main]-Issue in TDS calculation during payment application against invoices

> Fixed TDS calculation during payment application against invoices by scaling the applied amount to match the payment's TDS base, ensuring correct tax base computation when GST and payment amounts differ.

[Pull request](https://github.com/microsoft/BCApps/pull/9552) · merged into `main` (BC30) on 2026-07-17 by v-ajaztabrez (community contribution) · 2 files (+166 -100), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Applied amount on TDS advance payments is now scaled to the payment's TDS base instead of using the gross, GST-inclusive Amount to Apply
- Formula: Amount to Apply × (Payment TDS Base ÷ Payment Amount), both taken from the payment's own TDS Entry
- Scaling only applies when the payment's TDS base differs from its amount
- Consumed original invoice amount is now scoped to the applied payment, which fixes wrong results on a second payment/invoice pair
- Use case version bumped to 36 (JSON and registry) so it gets reimported
- Behaviour changes for users or extensions.
