Calculation of late interest on GST with example
Example -1
ABC ltd needs to pay the GST of ₹ 10 lakh on or before 20th May, 2018. However, it only manages to pay the tax on 20th June, 2018. Please calculate the Interest on tax which is to be paid.
To calculate the correct interest we need the following:
- Interest rate (18% as per section 50)
- No. of days default (31 days, we shall not count 20th may)
- Outstanding tax (Which is ₹ 10 lakh)
Hence, interest on late payment of tax will be ₹ 15,287/- (10 lakh*18%*31/365).
Example -2
Suppose for month of July
Output GST=100000
Input GST=80000
GST payable=20000
This 20000 we have to pay by 20 August (20 of Next Month)
In case we pay the same on 24 August, we are 4 days late
Interest will be calculated as follows
=20000*4/365*18%=39.45
Interest will be rounded off to 39
Total amount payable =20000+39=20039
