This discussion explores whether interest is applicable on Tax Deducted at Source (TDS) payments when a vendor invoice is received late. The consensus is that if the invoice pertains to a previous month (e.g., October) but is received in the current month (e.g., November), no interest is payable on the TDS if no liability was recorded in the accounts for the original month. Additionally, for Goods and Services Tax (GST) purposes, Input Tax Credit (ITC) can only be claimed in the month the tax invoice is received, meaning ITC for an October invoice received in November would be claimed in November.
