fix: better indicator base amount for Tax Witholding in Journal Entry

[vorasmit]

Support Ticket: https://support.frappe.io/helpdesk/tickets/26923

Use case

Over deduction of TDS from Journal Entry for an expense booked.

Issue

Excess amount reported forms part of income of supplier if reported as is.

Implementation

Base amount for TDS is lower of total JV value or reverse calculation (from tax rate and tax amount being deducted)
This is to based on the assumption that supplier is deducting TDS manually while staying compliant and there is no under deduction.

backport to version-14 and version-15 is expected

Hello @ruthra-kumar
any update on this ???

Is there any way to identify a TDS overbooked scenario, especially through Journal? If so, we can simply report it as overbooked through a new column in the report, rather than approximation.

How about this approach?

• User creates a Journal Entry
• We estimate base tax amount and set it automatically in a field (based on reverse calculation) in Journal Entry
• User updates this field if he wants

This field than forms basis for the base TDS amount.

I'm not sure. Adding one more field to Journal Entry further increases complexity and maintenance. Unfortunately, using Journal Entry for everything has lead to this unavoidable ambiguity.

How about a new doctype just for booking TDS? similar to how Landed Cost Voucher works. This allows for separation of concern and better traceability of TDS amounts

Bigger project. I'll think about it. Until then maybe we keep this fix and take this up as a refactor
