Book Entries and adjustment of interest

The reports on interest amounts calculated in different ways simple give the interest implications, but these have not been brought into books. The same can be booked using debit or credit note with voucher class.

Using Debit Notes and Credit Notes with Voucher Classes

Use Debit Note for interest receivables and Credit Note for interest payable. Interest is calculated on Simple or Compound basis and separate classes should be used for these.

Set-up Debit/Credit Note Classes for interest entries

To create voucher class for booking interest receivable

1.     Go to Gateway of Tally > Accounts Info > Voucher Types > Alter

2.     Enter the name of the class in the field Name of Class field.

3.     Enable the option Use Class for Interest Accounting.

Enable the option Use Class for Interest Accounting

4.     Press Ctrl+A to save Voucher Type Class.

5.     Press Ctrl+A to save Voucher Type Alteration.

Similarly create a voucher class Compound Interest and set Amounts to be treated as Compound Interest to Yes.

Create a ledger Interest Received under the group Indirect Income for booking the interest value.

Voucher Entry for booking Interest

There are two situations for interest adjustment:-

·       Simple Interest – Interest amounts are not debited onto the same bills. Create a fresh reference for it.

·       Compound Interest – Amounts are auto-debited to the selected bills. Bill-wise details will not appear in this case.


·       Interest on balances only

Bill-wise interest entry

To create a voucher for booking the interest

1.     Go to Gateway of Tally > Accounting Voucher > Crtl+F9: Debit Note

2.     Debit the party ledger

o      Select the bills to adjust from the List of Interest Bills in the Interest Details screen.

 List of Interest Bills in the Interest Details screen

o      Press Enter.

3.     Select New Ref in the Bill-wise Details screen.

4.     Credit the ledger Interest Received grouped under Indirect Income.

 The debit note for simple interest appears as shown below:

debit note for simple interest

5.     Press Enter to save.

Entries for compound interest are exactly the same as simple interest where all you do is select the voucher class created for compound interest. Also the Bill-wise Details sub-screen is not displayed as the amounts are automatically added onto the bills.

The Ledger Outstandings will be as shown below:

 Ledger Outstandings

The bill no. 113 is the invoice onto which interest has been compounded.

A new reference no 6 has been created for simple interest due from the party.

Entries for Interest on Balances only

Again, the issues are simple and compound interest.

Compound Interest

Record the following entries in a debit note with compound interest voucher class.

·       Debit bank account (the amount is automatically filled up with the calculated interest)

·       Credit Interest Received

The bank account has been increased by the amount of interest due and the income account of Interest Received also credited.

Simple Interest

Record the same entry as in case of compound interest, however, since it has the effect of increasing the bank account with the amount due (compound effect), you must make a journal entry to reverse it. The reversal entry would be as shown below:

·       Debit Interest Receivable (created under Current Assets group)

·       Credit bank account

Use a normal Journal voucher for this entry.

We have to necessarily debit the bank account in first place to take advantage of the auto filling of the interest amount.
