Why Some Business Expenses Don't Lower Your Taxes

Section 40 Simplified for Business Owners

As a business owner, you know that spending money on your business usually helps lower your taxable profit. But the tax department has specific "deal-breaker" rules. Even if a cost is real, the tax office might ignore it. This means your profit looks higher on paper, and you end up paying more tax.

1. The "Pre-Paid Tax" Rule (TDS)

When you pay vendors, you must keep a part of the payment and send it to the government as their tax.

  • Foreign Payments: Lose 100% of the tax benefit if missed.
  • Local Payments: Lose 30% of the tax benefit if missed.

2. Your Own Income Tax

You cannot count the Income Tax you pay as a business expense. The law sees this as a share of your success, not a cost of doing the work.

3. Rules for Business Partners

If you run a Partnership or LLP, there are strict limits on owner pay:

Salary: Capped based on profit (e.g., 90% of the first ₹6 Lakhs).

Interest: Capped at 12% per year. Anything extra is ignored.

4. Avoid Large Cash Payments

Payments over ₹10,000 in cash to one person in a day are 100% ignored by the tax office. Use Bank Transfers, Cheques, or UPI instead.
