Why Did a ₹100 Product Become ₹133? The Story Behind the Cascading Effect of Tax in India

 Simple is my brand. Clarity is my style.

Have you ever wondered why products sometimes become much more expensive by the time they reach consumers?

Imagine a product that costs only ₹100 to manufacture. Yet by the time it reaches the customer, its price has risen to over ₹133.

Where did those extra ₹33 come from?

Was the product improved?

Did the retailer become greedy?

Not really.

The answer lies in something economists call the Cascading Effect of Tax, popularly known as Tax on Tax.

A Journey of a Simple Product

Let us travel back to the period before GST.

Suppose a manufacturer produces a product at a cost of ₹100.

The government imposes an excise duty of 10%.

Therefore:

  • Production Cost = ₹100
  • Excise Duty = ₹10
  • Invoice Value = ₹110

Everything seems perfectly normal so far.

But the story does not end here.

Enter the wholesaler.

The wholesaler purchases the product for ₹110.

Now the state government imposes VAT at 10%.

But here is the catch.

VAT is not calculated on ₹100.

It is calculated on ₹110 – a value that already includes the previous tax!

Therefore:

  • Purchase Price = ₹110
  • VAT @10% = ₹11
  • Invoice Value = ₹121

In simple words, the wholesaler is paying tax on a value that already contains tax.

The chain of Tax-on-Tax has begun.

Finally Comes the Retailer

The retailer buys the product for ₹121.

Again, VAT at 10% is applied.

This time:

  • Purchase Price = ₹121
  • VAT @10% = ₹12.10
  • Final Price = ₹133.10

And who pays this entire burden?

You and I—the final consumers.

A product that originally cost ₹100 now costs ₹133.10.

This is the cascading effect.

But Why Did This Happen?

The biggest reason was the absence of input tax credit (ITC).

Businesses could not claim credit for taxes paid at earlier stages.

As a result:

  • Every stage treated the previous tax as part of its cost.
  • Every new tax was calculated on the already-taxed amount.
  • The burden kept increasing.

This was one of the biggest weaknesses of India's pre-GST tax system.

The Problems Created by Tax-on-Tax

The cascading effect created several challenges:

Higher Prices for Consumers

Products became unnecessarily expensive.

Burden on Businesses

Businesses had to absorb taxes without getting any credit.

Reduced Competitiveness

Indian products became costlier in global markets.

Complex Tax Structure

Excise duty, VAT, service tax and CST operated independently without coordination.

The system became difficult to understand and administer.

India needed a better solution.

Then Came GST

On 1st July 2017, India introduced the Goods and Services Tax (GST).

One of the greatest strengths of GST is the input tax credit (ITC).

Under GST:

  • Tax paid at one stage becomes a credit at the next stage.
  • Businesses pay tax only on the value they add.
  • Tax-on-tax is eliminated.
  • Consumers benefit from lower prices and greater transparency.

In other words, GST broke the chain of cascading taxation.

Before GST vs After GST

Before GST

Multiple taxes

No seamless Input Tax Credit

Higher prices

 Complex compliance

After GST

 Unified tax structure

 Seamless ITC

 Lower tax burden

 Transparent and technology-driven system

Final Thoughts

The story of the cascading effect teaches us an important lesson.

Sometimes, the problem is not the tax rate itself.

The problem lies in how taxes are designed.

GST was not introduced merely to replace old taxes.

It was introduced to eliminate the unfair burden of tax-on-tax and create a more efficient and transparent tax system.

The next time you hear the term 'input tax credit', remember that it is not just a technical concept—it is the mechanism that prevents a ₹100 product from becoming unnecessarily expensive.Watch the complete video: CLICK HERE
