Running a shop means managing vendors, payments, and expenses daily. But from 2024 onwards, a new tax rule is quietly impacting small businesses across India.
Many shop owners are unaware that delayed payments to MSME vendors can increase their taxable income even if the expense is genuine.
Under Section 43B(h), timing of payment matters more than ever.
In this article, let’s break down what this rule means and how you can avoid unnecessary tax burden.
If you purchase goods from an MSME vendor and delay payment:
❌ The expense is not allowed as deduction
📈 Your profit increases on paper
💸 You end up paying extra tax
This is where most shop owners get confused.
You already paid (or will pay) the vendor.
But because of delay, the expense is disallowed in that year.
👉 Result:
Higher taxable income
Higher tax — without real profit
There’s another hidden risk.
Under Rule 37A:
👉 If your vendor doesn’t file GST properly
👉 Your Input Tax Credit (ITC) can be blocked
So now you must track:
Using notebooks or spreadsheets?
You may miss:
Even one mistake can cost lakhs in tax.
To stay safe:
✔ Check MSME status of vendors
✔ Track invoice ageing (30+ days)
✔ Pay on time
✔ Use software instead of manual tracking
