Quick Answer

In TallyPrime, the option:

“Supplies under section 7 of IGST Act: Yes / No”

does not simply mean “Is this an interstate sale?”

Section 7 of the Integrated Goods and Services Tax (IGST) Act, 2017 defines transactions that are treated as inter-State supplies. These include ordinary supplies between different States/Union Territories, but also special situations such as imports, supplies where the place of supply is outside India, and supplies to or by an SEZ developer/unit.

However, in TallyPrime, this Yes/No field is particularly important when you have overridden or altered the normal GST determination—for example, where Tally sees the party as local but the transaction legally needs to be treated as interstate/IGST because of Section 7. Tally's own documentation specifically instructs users to mark qualifying transactions as Section 7 supplies so they are handled correctly in GST reports.

Practical rule: For a normal Delhi seller billing a Haryana customer with Haryana as the place of supply, you normally do not need to manually mark this field Yes merely because IGST applies. Leave it at its normal/default setting. Select Yes when the transaction is a specific Section 7 scenario requiring Tally to accept an interstate/IGST treatment that would otherwise conflict with the party, place-of-supply, country, or nature-of-transaction information.

What Is “Supplies Under Section 7 of IGST Act” in TallyPrime?

While recording certain interstate sales, purchases, exports, imports, courier services, or other GST transactions in TallyPrime, you may encounter an additional screen such as:

Additional Details: Interstate Sales – Taxable
Supplies under section 7 of IGST Act: Yes / No

This small Yes/No option can be confusing because the voucher may already be classified as Interstate Sales – Taxable.

This raises an obvious question:

If the transaction is already interstate and IGST is being charged, why does TallyPrime separately ask whether it is a supply under Section 7 of the IGST Act?

The answer is that the field has a more specific purpose than simply identifying every ordinary interstate sale.

---

What Is Section 7 of the IGST Act?

Section 7 of the Integrated Goods and Services Tax Act, 2017 is titled:

“Inter-State supply.”

It forms part of Chapter IV dealing with the determination of the nature of supply.

Under Section 7(1), subject to the applicable place-of-supply provisions, a supply of goods is interstate when the supplier's location and place of supply are in:

• two different States;
• two different Union Territories; or
• a State and a Union Territory.

Similarly, Section 7(3) covers services where the supplier's location and place of supply are in different States/UTs.

But Section 7 goes further than an ordinary Delhi-to-Haryana transaction.

---

What Transactions Are Covered by Section 7?

Section 7 broadly covers the following situations:

This classification comes directly from Section 7 of the IGST Act.

Therefore, Section 7 includes both normal interstate transactions and certain special transactions that are legally deemed/treatable as interstate.

---

The Most Important Point for TallyPrime Users

This is where many users misunderstand the option.

Suppose your business is registered in Delhi and you sell goods to a customer in Haryana, with Haryana being the place of supply.

TallyPrime can normally determine from the transaction details that this is an interstate transaction.

It will accordingly classify the transaction as interstate and calculate:

IGST

instead of:

CGST + SGST

You ordinarily do not need to manually tell Tally:

“Supplies under section 7 of IGST Act = Yes”

just because it is an ordinary interstate sale.

The separate Section 7 flag becomes particularly useful where the information in the voucher would normally cause TallyPrime to expect a different tax treatment, but the transaction must legally be treated as interstate.

Tally's documentation confirms this behavior in several special scenarios.

---

Why Does TallyPrime Provide Yes and No?

TallyPrime normally determines the nature of supply using information such as:

Company State + Party State/Country + Place of Supply + Nature of Transaction + GST registration details.

For an ordinary transaction, these values should agree with each other.

For example:

Company: Delhi
Customer: Haryana
Place of Supply: Haryana
Nature: Interstate Sales – Taxable
Tax: IGST

There is no unusual conflict.

But imagine:

Company: Karnataka
Customer: Karnataka
Destination/place-of-supply circumstances: Outside India
Nature selected: Interstate Sales – Taxable

From the party's State alone, this may appear to be a local transaction.

Yet applicable place-of-supply/IGST provisions may require it to be treated as interstate.

This is the kind of situation where the Section 7 indication becomes significant.

Tally explains that certain transactions can otherwise appear as exceptions because the nature of transaction has been altered. Marking the qualifying transaction as a Section 7 supply allows it to be treated appropriately for GST reporting.

---

Simple Decision: Should I Select Yes or No?

Use this practical guide:

The important distinction is:

Do not treat “Yes” as a general-purpose “this is an interstate invoice” button.

---

Example 1 – Normal Interstate Sale

Suppose:

Seller: BISON, Delhi
Customer: ABC Computers, Haryana
Goods delivered to: Haryana
Taxable value: ₹1,00,000
GST rate: 18%

This is a normal interstate supply.

GST calculation:

IGST @ 18% = ₹18,000

Invoice total:

₹1,18,000

TallyPrime can determine that the transaction is interstate from the party/place-of-supply information.

Therefore, there is normally no reason to manually use the Section 7 override/flag merely because IGST is being charged.

Recommended setting

Supplies under section 7 of IGST Act: No/default

---

Example 2 – Normal Local Sale

Suppose:

Seller: Delhi
Customer: Delhi
Place of Supply: Delhi

This is normally an intra-State supply.

For an 18% GST item:

CGST = 9%
SGST = 9%

The Section 7 option should not be used to convert a genuine local supply into an interstate supply.

Setting

Supplies under section 7 of IGST Act: No

---

Example 3 – Same-State Parties but Special Interstate Treatment

This is where the feature becomes much more important.

Tally gives an example involving courier services where the courier agency and sender may both be located in the same State, but the goods are transported to a destination outside India.

Tally explains that the transaction may need to be treated as interstate and directs users to:

Nature of Transaction → Interstate Sales – Taxable

and then:

Supplies under section 7 of IGST Act → Yes

for the applicable scenario.

Here, simply looking at the supplier's and customer's States could suggest:

Local transaction → CGST + SGST

but the applicable GST/place-of-supply rules require:

Interstate treatment → IGST

That is a classic example of why this TallyPrime field exists.

---

Example 4 – Import of Services

Suppose an Indian business purchases a qualifying service from a supplier located outside India.

Section 7(4) specifically states that the supply of services imported into India shall be treated as a supply in the course of interstate trade or commerce.

Tally's current documentation for recording import of services instructs users to configure the transaction as Interstate Purchase Taxable, use IGST as applicable, and enable:

Supplies under section 7 of IGST Act.

Therefore:

Section 7

Yes

subject to the transaction actually satisfying the applicable GST provisions.

---

Example 5 – Supply to or by an SEZ

Section 7(5)(b) specifically includes supplies:

to or by a Special Economic Zone developer or Special Economic Zone unit

as interstate supplies.

This is important because an SEZ transaction can be interstate for GST purposes even where the geographical State comparison might otherwise make the transaction appear local.

However, SEZ transactions have their own GST treatment and TallyPrime transaction configurations. Do not simply change the Section 7 field without configuring the transaction correctly as an SEZ supply.

---

What Happens When You Select “Yes”?

When you select:

Supplies under section 7 of IGST Act = Yes

you are effectively indicating to TallyPrime that the transaction's interstate nature is valid under Section 7 even though the other information in the voucher may create an apparent mismatch.

This helps TallyPrime correctly process qualifying transactions for GST reporting.

Tally documents that Section 7 supplies can also be resolved from GST exception reports. In GSTR-3B, for example, qualifying transactions can be selected and updated as Section 7 supplies so that the exception is resolved and the transaction is included in the return.

---

What Happens If You Leave It as No?

For an ordinary interstate transaction, No/default is not a problem.

TallyPrime can determine interstate status normally from the transaction.

However, if you have a special transaction that should legitimately be treated as interstate under Section 7, but its party/place-of-supply information creates an apparent mismatch, leaving the Section 7 indication unset may cause the voucher to appear under GST exceptions or incomplete/mismatched information.

Tally specifically documents such behavior for qualifying Section 7 transactions.

---

Does “No” Mean Section 7 Is Legally Not Applicable?

This requires an important distinction between the law and TallyPrime's software field.

Legally, an ordinary Delhi-to-Haryana sale is an interstate supply covered by Section 7(1).

But that does not mean you need to manually mark every such voucher “Yes” in TallyPrime.

Tally already knows that an ordinary transaction is interstate from its normal GST details.

Therefore:

Legal classification: The transaction can fall under Section 7.

TallyPrime field: The Yes option is especially used to identify/validate transactions needing Section 7 treatment where Tally's normal determination has a conflict or special circumstance.

This distinction is crucial.

---

Why Not Select “Yes” for Every Interstate Sale?

That is not recommended.

The Section 7 field should reflect the actual nature and circumstances of the transaction.

Using it indiscriminately can hide an underlying data-entry problem.

For example, suppose you accidentally enter:

Company: Delhi
Customer: Delhi
Actual supply: Delhi
Nature of Transaction: Interstate Sales – Taxable

Tally may detect an inconsistency.

The solution is not to select:

Supplies under Section 7 = Yes

just to make the warning disappear.

Instead, correct the Nature of Transaction to the appropriate intra-State classification.

---

Section 7 Is Not a “Force IGST” Button

This is probably the most useful rule to remember.

Do not think of the option as:

“I want IGST, so I will select Yes.”

Instead, think:

“This transaction legitimately falls under a Section 7 interstate scenario, and Tally needs confirmation because its normal GST determination does not fully match the transaction.”

If IGST is appearing incorrectly, investigate the underlying details first.

---

What Should You Check Before Selecting Yes?

Before changing the option, verify:

1. Supplier's State
2. Customer's State/country
3. GSTIN
4. Place of Supply
5. Nature of Transaction
6. Whether goods or services are involved
7. Whether the transaction is an import/export
8. Whether an SEZ is involved
9. Applicable place-of-supply provisions
10. Whether IGST or CGST+SGST should legally apply

Tally itself advises checking the Place of Supply, State of the Buyer, and Nature of Transaction when resolving IGST/interstate mismatches.

---

How to Identify a Possible Section 7 Issue in TallyPrime

A common clue is an error or exception along the lines of:

IGST is mandatory for interstate supply and CGST & SGST should not be present

Tally says this can occur when:

• the Nature of Transaction is overridden;
• the Place of Supply is changed; or
• the transaction is a Section 7 supply requiring IGST despite other information suggesting a different treatment.

Do not immediately mark Section 7 as Yes.

First determine whether the voucher is actually correct.

---

How to Correct a Section 7-Related GST Exception

If TallyPrime reports an interstate/IGST mismatch:

Step 1: Note the affected voucher or invoice number.

Step 2: Open the voucher.

Step 3: Check the customer's State and GST registration details.

Step 4: Verify the Place of Supply.

Step 5: Check the Nature of Transaction.

Step 6: Determine whether the transaction genuinely qualifies for special interstate treatment under Section 7.

Step 7: If it genuinely qualifies, open the GST/Statutory Details and set:

Supplies under section 7 of IGST Act → Yes

Tally also provides facilities within its GST reports to update qualifying transactions as Section 7 supplies.

---

Yes vs No – Final Practical Comparison

---

Common Mistake: “Interstate = Section 7 Yes”

This is the most common misunderstanding.

Technically, Section 7 is the statutory provision defining interstate supplies, so an ordinary interstate supply can indeed be covered by Section 7.

But the TallyPrime Yes/No field should not be interpreted as a generic interstate selector.

For normal interstate transactions, Tally determines the tax treatment from the transaction data.

The special Section 7 indication is particularly relevant where Tally needs confirmation that an apparently unusual interstate treatment is legitimate.

Frequently Asked Questions

1. What is Section 7 of the GST Act?

More precisely, it is Section 7 of the IGST Act, 2017. It defines supplies that are treated as interstate supplies, including normal cross-State supplies and certain imports, exports/place-of-supply-outside-India situations, SEZ supplies, and other specified transactions.

2. Does Section 7 mean IGST is applicable?

Section 7 determines whether a supply is interstate. Interstate classification is fundamental to determining IGST treatment, but the final tax treatment can also depend on other GST provisions, exemptions, zero-rating, reverse charge and place-of-supply rules.

3. Should I select Yes for every interstate sale in TallyPrime?

No. For a normal interstate transaction correctly identified from the party and place-of-supply information, you ordinarily leave the Section 7 field at its normal/default setting.

4. My company is in Delhi and customer is in Haryana. Should I select Yes?

For a normal sale delivered/place-of-supply in Haryana, normally no manual Section 7 flag is required. Tally should determine it as interstate and calculate IGST from the normal voucher details.

5. My company and customer are both in Delhi. Can IGST still apply?

In certain special situations, yes. The nature of supply depends on the statutory place-of-supply and IGST provisions, not merely the mailing addresses of seller and buyer.

6. Can I select Yes to remove a Tally GST error?

Only if the transaction genuinely qualifies as a Section 7 supply.

Do not use the setting simply to suppress a GST exception.

7. What if I select Yes incorrectly?

You risk incorrectly validating the nature of the transaction in your accounting/GST data. Review the voucher and correct the GST classification before filing returns.

8. Is import of services covered by Section 7?

Yes. Section 7(4) provides that imported services are treated as interstate supplies.

9. Are supplies to SEZ covered?

Yes. Section 7(5)(b) specifically covers supplies to or by an SEZ developer or SEZ unit as interstate supplies.

10. Why does TallyPrime show this field under “Additional Details: Interstate Sales – Taxable”?

Because it allows TallyPrime to identify a qualifying transaction whose interstate treatment is specifically being asserted under Section 7, particularly where normal party/place-of-supply information creates a mismatch.

---

Troubleshooting Checklist

If you are unsure whether to choose Yes or No, do not guess.

Check:

Party State → Place of Supply → Country → Nature of Transaction → GSTIN → applicable place-of-supply rule → correct tax type.

If all details naturally establish an ordinary interstate transaction, let TallyPrime handle it normally.

If there is an unusual situation where the transaction must legally be interstate despite apparently conflicting details, investigate whether it is genuinely covered by Section 7 before selecting Yes.

---

Conclusion

The “Supplies under section 7 of IGST Act – Yes/No” option in TallyPrime is easy to misunderstand.

Section 7 of the IGST Act defines interstate supplies and includes ordinary cross-State supplies as well as special situations involving imports, certain supplies with place of supply outside India, SEZs and other specified transactions.

But in TallyPrime, you should not mechanically select Yes for every interstate invoice.

For normal interstate transactions, TallyPrime generally determines IGST treatment automatically from the supplier, party and place-of-supply information. The Section 7 flag becomes particularly relevant where a qualifying transaction has been given interstate treatment despite other voucher information creating an apparent mismatch.

The safest working rule is:

Normal interstate transaction correctly identified by Tally → leave Section 7 at No/default.

Special transaction genuinely requiring Section 7 interstate treatment despite otherwise conflicting information → select Yes.

And most importantly:

Never select “Yes” merely to remove a TallyPrime GST warning. First confirm why the transaction legally requires interstate/IGST treatment.

For the statutory wording, refer to the official IGST Act on India Code. For software-specific handling, Tally's official guidance includes examples for Section 7 courier/export-service transactions in TallyPrime and import of services under Section 7 in TallyPrime.
