GST Interest Calculator – Estimate Interest Now

A GST Interest Calculator is a tool available online to calculate the interest payable on late payment of GST for taxpayers, business owners, traders, freelancers and accountants in India. When a registered taxpayer doesn’t pay the correct amount of GST on time, interest may be charged.

The interest will generally be charged on the outstanding tax. The rate of interest and calculation for interest will vary based on the situation.

The interest in most cases will be payable when the taxpayer doesn’t pay their GST on time (Section 50 of the Central Goods and Services Tax Act 2017). In most cases, the interest rate for late tax payment is 18%. However, this can vary in certain situations such as overclaiming input tax credit.

To calculate the interest payable on late payment of GST, simply enter the amount of outstanding tax, interest rate and number of days into the GST Interest Calculator.

For example, if your outstanding GST is ₹50,000 and you’re paying late by 30 days, with an interest rate of 18% per year you’d pay around ₹740 interest.

Whether you’re a small business owner, GST registered professional, retailer, wholesaler or accountant, this GST Interest Calculator will help you to estimate interest charges on late payments.

GST Interest Calculator Formula

In most cases, the interest is calculated using the simple interest formula.

GST Interest = (Tax Outstanding x Interest Rate x Late Days) / (100 x 365)

Where:

Tax Outstanding = Amount of GST that is outstanding.

Interest Rate = Percentage of interest applicable per year.

Late Days = Number of days the interest is payable for.

365 = Number of days in a year.

Total Amount Payable Formula

Once you’ve calculated the interest, you can work out how much you’ll need to pay in total.

Total Amount Payable = Tax Outstanding + Interest

If you have an outstanding tax of ₹10,000 and an interest of ₹150, the calculation will be:

Total Amount Payable = ₹10,000 + ₹150

Total Amount Payable = ₹10,150

The calculator will use these formulas to calculate an estimate.

Example GST Interest Calculator

Let’s take a look at how the GST Interest Calculator works.

Say you’re a small business owner in India. You have an outstanding GST of ₹50,000. You were meant to pay on 20 th September, however you paid 30 days late. The interest rate is 18% per year.

Step 1: Tax Outstanding

Tax Outstanding = ₹50,000

Step 2: Interest Rate

Interest Rate = 18%

Step 3: Late Days

Late Days = 30

Step 4: GST Interest Formula

GST Interest = (50,000 x 18 x 30) / (100 x 365)

GST Interest = 27,000,000 / 36,500

GST Interest = ₹739.73

Step 5: Total Amount Payable

Total Amount = ₹50,000 + ₹739.73

Total Amount Payable = ₹50,739.73

Below shows all the calculations:

Description Amount

Tax Outstanding ₹50,000

Interest Rate 18%

Late Days 30 Days

Interest ₹739.73

Total Amount Payable ₹50,739.73

This shows how the interest will increase depending on the amount of tax outstanding and how many days it was late.

Understanding the Results of the GST Interest Calculator

Once you’ve entered the details, you’ll see various figures pop up.

These will include:

• Tax Outstanding – This is how much tax you owe.
• Interest Rate – This is the rate of interest that will be applied per year.
