MultiPeriod Accounting Day-wise proration

We have configured day-based Multiperiod Accounting on the invoice item line from 01-Apr-2026 to 31-Mar-2027. Expense accounting is being prorated correctly and deferred to the prepaid account. However, CGST, SGST, and TDS on GST are recognized fully on the invoice accounting date and are not deferred through the MPA schedule. Kindly confirm whether GST and withholding tax distributions are excluded from Multiperiod Accounting by design, or whether additional setup is required to prorate tax amounts on a day-wise basis.
