Section 40A of the Income Tax Act – Disallowance Rules Explained

blog

Dev owns a medium-sized shop, the worth of which is ₹20,00,000. He purchases the products he uses in the business and pays his employees. In some cases, he pays with cash.

 

However, the tax regulations indicate that there are constraints that he should observe when paying in cash. Failure to which, his costs will not be quantifiable, and he will be forced to pay a higher tax.

Key Points of Section 40A:
 

  • This applies to business expenses paid in cash.
     
  • Sets limits on cash payments:
    • ₹10,000 per day to a single person (for expenses).
    • ₹35,000 per day for transport (like hiring a truck).
       
  • If you pay more than the limit, the expense won’t count for tax.
     
  • Bank/electronic payments (like UPI and cheque) have no limits.

 

Example Table
 

Payment Type

Limit

Allowed for Tax?

Cash to the supplier

₹10,000/day

No if exceeded

Cash for transport

₹35,000/day

No if exceeded

Bank transfer

No limit

Yes

Why it matters:
 

  • Helps track money and reduce tax evasion.
     
  • Encourages digital payments.

 

Dev has started to give his workers payments through a bank to escape issues. Simple!

Importance of Section 40A

 

Dev is the owner of a small grocery shop. He gets materials and remunerates his assistant in cash. However, by not adhering to the rules of taxes, his spending can be disapproved, and he will end up paying an additional tax.

Why Section 40A Matters:
 

  • Stops Tax Evasion: Prevents fake cash payments to hide income.
     
  • Encourages Digital Payments: Bank/UPI payments have no limits, making records clear.
     
  • Keeps Business Fair: Everyone follows the same rules, without cheating, because it is good for us.
     
  • Avoids Extra Tax: If Dev pays ₹15,000 cash to a supplier (over the ₹10,000 limit), the expense is not allowed, increasing his taxable profit.

  • Follow the rules to save money and stay safe.

Objectives of Section 40A

 

Dev owns a small stationery shop. He buys pens and notebooks, and pays his delivery boy. The tax department wants businesses like Dev’s to be honest and transparent. Section 40A helps with this.

Main Objectives of Section 40A:

 

  • Stop Fake Cash Expenses: Prevents businesses from showing fake payments to reduce tax.
     
  • Encourage Digital Payments: Promote bank transfers, UPI, or cheques for better records.
     
  • Set Cash Payment Limits: Keeps cash transactions small to track money easily.
     
  • Reduce Tax Evasion: Makes sure businesses pay the right tax without hiding cash deals.

TDS Rules Under Section 40A
 

Dev also owns a store that deals with stationery and occasionally employs temporary workers or orders in bulk. According to the tax department, he has to deduct TDS (Tax Deducted at Source) in some instances in making payments.

Key TDS Rules Under Section 40A:
 

  • No TDS on Cash Payments Below ₹10,000: Small cash payments don’t need TDS.
     
  • TDS on Contractor/Professional Payments Over ₹30,000: If Dev pays a freelancer or repairman over ₹30,000 in a year, he must deduct 1-10% TDS (depending on the work).
     
  • No TDS on Digital Payments: Bank transfers, UPI, or cheques don’t require TDS under this section.

  • Make payments online to avoid TDS on cash payments
     
  • Record your keys to ensure that you are not found tax non-compliant.

  • TDS Return Filing: Dev must file quarterly returns by 31st July, 31st October, 31st January, and 31st May
    .
  • Cash Expense Record-Keeping: Dev must maintain bills/receipts for 6 years in case tax officers check.

  • Keep digital/physical copies of all payment proofs.
     
  • File returns on time to avoid penalties.

 

Practical Examples 

 

  • Buying Supplies: Dev pays ₹9,500 cash for notebooks - allowed (under ₹10,000 limit). Pays ₹11,000 cash - not allowed (over limit).
     
  • Hiring Workers: Pays ₹8,000 cash to a temporary helper - no TDS. Pays ₹35,000 to the electrician via bank - deducts 1% TDS (₹350).
     
  • Rent Payment: Pays ₹15,000 shop rent via UPI - no restrictions. Pays ₹20,000 cash - not allowed (must be digital).
     
  • Farmer Purchase: Buys ₹12,000 handmade paper from a farmer in cash-exempt (agricultural payment).

Conclusion 

 

The provision of section 40A enables business owners of small firms such as Dev to receive clear rules of taxation in the course of their shops. Dev can evade penalties in taxation through the knowledge of the cash limits (₹10,000 per payment) and the TDS requirements (those payments would exceed ₹30,000 to professionals). 

 

The law advises people to use digital payments when the sum is large, but they can use small sums of money to fulfil their daily necessities. 

 

Dev is taught how to make a ₹9,000 cash payment to his supplier and pay him ₹15,000, which will be through UPI. His work is more simplified with special exemptions on salaries and farmer payments. Dev can manage to remain compliant by recording records properly and abiding by the deadlines. These are the basic things that his stationery business should be doing to expand and abide by the rules of the taxes.
