Adding and Applying Discount in TallyPrime

Learning Objective: This guide explains how to enable the discount column in TallyPrime, apply item-wise discounts, use a discount ledger, calculate GST after discount, and understand different types of discounts through practical examples.

1. Enabling the Discount Column

TallyPrime can display a separate discount column while entering items in sales or purchase invoices. This is particularly useful when the discount is different for each item.

1 Go to:
Gateway of Tally → F11 (Features) → Inventory Features
2 Turn ON the option:

Use discount column in invoices
3 Select the required discount format:
  • Percentage – Example: 10%
  • Amount – Example: ₹500
  • Both Percentage & Amount – Useful when both values need to be visible.
Tip: Item-wise discount is convenient when different products have different discount rates. For example, Product A may have 10% discount while Product B may have 5%.

2. Applying Discounts in a Sales Voucher

Once the discount column is enabled, you can enter the discount while creating a sales invoice.

1 Go to:
Gateway of Tally → Vouchers → Sales (F8)
2 Select the Party Ledger, i.e. the customer.
3 Enter the stock item details:
  • Stock Item
  • Quantity
  • Rate
  • Discount
4 Enter the discount in the Disc% column if the discount is percentage-based.

Example: Item-wise Discount

Suppose Product A is sold for ₹500 per unit and the customer receives a 10% discount.

Gross Value = ₹500
Discount = ₹500 × 10% = ₹50
Net Value = ₹500 − ₹50 = ₹450

Therefore, the taxable value for that item becomes ₹450, subject to the applicable tax rules and configuration.

3. How Discount Affects GST

When an eligible discount is entered at the invoice/item level, the taxable value is generally reduced before GST is calculated. The exact tax treatment depends on the nature and timing of the discount and applicable GST rules.

Simple GST Calculation

Description Amount
Product value ₹5,000
Discount @ 10% ₹500
Taxable value ₹4,500
GST @ 18% ₹810
Invoice value ₹5,310
Important: Do not assume that every type of discount automatically reduces GST value. Discounts must satisfy the applicable GST provisions. In particular, post-supply discounts can have different tax implications. Always verify the treatment applicable to your transaction.

4. Using a Discount Ledger – Alternative Method

A discount ledger can be useful when the discount is treated as a separate accounting adjustment rather than an item-wise discount.

Step 1: Create the Discount Ledger

Go to:
Gateway of Tally → Accounts Info → Ledgers → Create

Suggested Ledger Name: Discount Allowed

Group: Indirect Expenses or another appropriate group based on your accounting policy.

Step 2: Record the Sales Voucher

  1. Enter the customer.
  2. Enter the stock items, quantities and rates.
  3. Allocate the appropriate discount amount.
  4. Review the accounting impact before saving the voucher.

Step 3: Review Tax Calculation

Check whether the discount has been configured and recorded in a way that correctly affects the taxable value under the applicable tax rules.

Step 4: Save the Voucher

Verify the final invoice amount, tax calculation and ledger postings before accepting the voucher.

5. Types of Discounts in TallyPrime

Discount Type How to Apply Example
Trade Discount Enter the discount in the item-level discount column. 10% discount on Product A.
Cash Discount Configure the relevant cash/trade discount option or record the discount according to the accounting procedure followed. ₹500 discount on the invoice total for prompt payment.
Multiple Discounts Use appropriate discount columns/configuration where supported, or record separate adjustments according to the business requirement. Trade discount + seasonal discount.

6. Detailed Example Scenario

Consider a sales invoice containing two products:

Product Quantity Rate Gross Value
Product A 10 ₹500 ₹5,000
Product B 5 ₹300 ₹1,500
Subtotal ₹6,500
Discount @ 10% ₹650
Net Taxable Value ₹5,850
GST @ 18% ₹1,053
Final Invoice Value ₹6,903
Subtotal = ₹6,500
Discount = ₹6,500 × 10% = ₹650
Net Value = ₹6,500 − ₹650 = ₹5,850
GST = ₹5,850 × 18% = ₹1,053
Final Value = ₹5,850 + ₹1,053 = ₹6,903

7. Item-wise vs Overall Discount

Feature Item-wise Discount Overall Discount
Applied to Individual stock items Total invoice or accounting adjustment
Example Product A – 10% ₹500 off the invoice
Best suited for Different discounts for different products Common discount or adjustment across an invoice
Where to look Disc% / Discount column Appropriate ledger or invoice-level configuration

8. Multiple Discount Example

Suppose a product has a gross value of ₹10,000 and the business gives two successive discounts:

  • Trade Discount = 10%
  • Seasonal Discount = 5%
First Discount = ₹10,000 × 10% = ₹1,000
Balance = ₹10,000 − ₹1,000 = ₹9,000

Second Discount = ₹9,000 × 5% = ₹450
Final Value = ₹9,000 − ₹450 = ₹8,550
Remember: Two successive percentage discounts of 10% and 5% are not the same as a single 15% discount. The second percentage is calculated on the amount remaining after the first discount.

9. Important Notes

  • For item-wise discounts, use the appropriate discount column.
  • For an overall adjustment, use the appropriate invoice/ledger mechanism based on your accounting requirement.
  • Verify the GST treatment of discounts according to the applicable GST provisions.
  • Restrict access to discount-related settings and entries where necessary to prevent unauthorized discounts.
  • Review discount reports and ledger balances regularly.
  • Before finalizing an invoice, verify quantity, rate, discount, taxable value, GST and final invoice amount.

10. Practical Workflow

Step 1: Enable the discount column.
Step 2: Open Sales Voucher using F8.
Step 3: Select the customer.
Step 4: Enter stock item, quantity and rate.
Step 5: Enter the applicable discount.
Step 6: Verify taxable value and GST.
Step 7: Verify the final invoice value.
Step 8: Accept/save the voucher.

11. Practice Questions

Question 1 – Basic Discount

A product is sold for ₹2,000. The customer receives a 10% discount. Calculate the discount amount and net value.

Show Answer
Discount = ₹2,000 × 10% = ₹200
Net Value = ₹2,000 − ₹200 = ₹1,800

A product has a value of ₹5,000. A 10% eligible discount is given. Calculate the taxable value and GST at 18%.

Show Answer
Discount = ₹500
Taxable Value = ₹4,500

Enable the discount column, enter the invoice and verify whether the taxable value and GST are calculated correctly.

Question 6 – Conceptual Question

When would you prefer an item-wise discount over an overall invoice-level adjustment?

Suggested Answer
An item-wise discount is preferable when different products have different discount rates or when the discount needs to be clearly associated with individual stock items.

12. Quick Revision

Topic Remember
Discount Column Enable it when item-wise discount entry is required.
Disc% Used for percentage-based item discounts.
Discount Amount Used when a specific discount amount needs to be entered.
Discount Ledger Useful for recording discounts as a separate accounting adjustment.
GST Verify the taxable value and applicable GST treatment after discount.
