GST ON ADVANCE

What is Advance Payment in GST?

Advance payment means money received before supplying goods or services. Under GST, tax liability may arise at the time of receiving advance, not just at the time of invoice.

Rules for GST on Advance

1. For Goods

  • ❌ GST is NOT applicable on advance received for goods.
  • βœ” GST is charged only when invoice is issued or supply happens.
  • This rule was changed after 2017.

2. For Services

  • βœ” GST is applicable on advance received for services.
  • βœ” Tax must be paid immediately when advance is received.

Scenario (Fake Example)

πŸ‘‰ Business: GD INFOTECH (Service – Coaching)

πŸ‘‰ GST Rate: 18%

πŸ‘‰ Advance Received: β‚Ή10,000 on 1 March

πŸ‘‰ Service Completed: 10 March

Step 1: Advance Received (1 March)

GST is applicable because this is a service.

Particulars Amount
Advance Amount β‚Ή10,000
GST @ 18% β‚Ή1,800
Total Received β‚Ή11,800

Journal Entry (Advance Received)

Bank A/c Dr. 11,800 To Advance from Customer A/c 10,000 To Output CGST A/c 900 To Output SGST A/c 900
βœ” Action: Issue Receipt Voucher

Step 2: Service Provided (10 March)

Now final invoice will be generated and advance GST will be adjusted.

Journal Entry (Invoice Raised)

Customer A/c Dr. 10,000 To Service Income A/c 10,000

Step 3: Adjust Advance Already Received

Advance and GST already paid on advance will now be adjusted against the invoice.

Journal Entry (Adjustment)

Advance from Customer A/c Dr. 10,000 To Customer A/c 10,000

Important Note

For services, GST is payable at the time of receipt of advance. For goods, GST is not payable on advance and arises only at the time of supply/invoice.

CAPITAL GOODS ITC NOTES

What are Capital Goods?

Capital goods are big assets used in business.

  • Generator
  • Machine
  • Computer
  • Furniture

Main Rule (Very Important)

βœ” Full ITC (Input Tax Credit) is allowed immediately

If:

  • Used for business purpose
  • Invoice is valid
  • Goods are received

Example

πŸ‘‰ Generator Purchase

Cost = β‚Ή20,000

GST = β‚Ή3,600

βœ” You can take full β‚Ή3,600 ITC immediately

❌ No need to divide in 5 years

Conditions for ITC

  • βœ” Used in business
  • βœ” Supplier filed GST return
  • βœ” Proper invoice available
  • βœ” Payment made within 180 days

When ITC is Not Allowed (Blocked Credit)

  • ❌ Motor car (in most cases)
  • ❌ Building construction
  • ❌ Personal use
  • ❌ Goods lost or destroyed

Special Rule – Rule 43

This rule applies only when capital goods are used partly for:

  • βœ” Business + Personal
  • βœ” Taxable + Exempt supplies
In mixed-use cases, ITC is divided over 60 months (5 years) and monthly adjustment is required.

Simple Meaning

βœ” Normal use = Full ITC
❌ Mixed use = Partial ITC

Depreciation Rule

If you claim depreciation on the GST amount, ITC is not allowed.

Reversal Case

If the asset is later used for:

  • Personal purpose
  • Exempt supply

βœ” Then ITC must be reversed proportionately.

Final Rule

Capital goods ITC is fully allowed immediately.
5-year rule applies only for adjustment under Rule 43 in mixed-use cases.

One-Line Exam Answer

ITC on capital goods is fully allowed, except in mixed-use cases where Rule 43 applies.

Mixed Use Case

If capital goods are used:

  • βœ” Partly for business + partly personal
  • βœ” OR partly for taxable + partly exempt work

Then you cannot take full ITC directly.

What to Do in Mixed Use?

  • βœ” Spread ITC over 5 years (60 months)
  • βœ” Do monthly adjustment
Monthly ITC = Total GST Γ· 60

Example of Mixed Use

Generator GST = β‚Ή3,600

Step 1: Monthly ITC = 3600 Γ· 60 = β‚Ή60 per month

Step 2: Usage = 70% business (taxable), 30% exempt/personal

Step 3:

βœ” Allowed ITC = 60 Γ— 70% = β‚Ή42 per month

❌ Reversal = 60 Γ— 30% = β‚Ή18 per month

What Happens Every Month?

  • βœ” Take β‚Ή42 as ITC
  • ❌ Reverse β‚Ή18
  • πŸ‘‰ Continue this for 60 months

Simple Understanding

πŸ‘‰ You are using the asset for both types of purposes.

πŸ‘‰ So GST benefit must also be divided.

Important Point

This rule applies only in mixed-use cases.
If fully used for business, no division is needed. Take full ITC immediately.

One-Line Memory Rule

Mixed use = ITC divided over 60 months.

Quick Summary Table

Situation ITC Treatment
Fully business use Full ITC immediately allowed
Mixed use ITC spread over 60 months
Personal use ITC not allowed
Exempt supply use Proportionate reversal required
Depreciation claimed on GST amount ITC not allowed

RCM 2026 NOTES

What is RCM?

RCM (Reverse Charge Mechanism) means the buyer/receiver pays GST instead of the seller.

Main Rule (Confirmed 2026)

βœ” RCM applies only in notified cases under Section 9(3) and Section 9(4)
❌ RCM is not applicable on normal purchases merely because the supplier is unregistered

Normal Purchase from Unregistered Dealer

For a normal purchase from an unregistered dealer, RCM is generally not applicable in 2026.

After the 2018 amendment, Section 9(4) does not say that every purchase from an unregistered person attracts reverse charge.

It applies only when the Government specifically notifies:

  • A class of registered persons, and
  • Specified categories of goods or services received from an unregistered supplier

Practical Rule

Normal purchases from unregistered dealer like stationery, office items, local repairs, small goods, and general business purchases do not attract automatic RCM.

RCM from Unregistered Dealer Applies Only in Notified Cases

  • Certain supplies to a promoter under notified provisions
  • Commercial rent from unregistered landlord to registered person
For rent, RCM applies not because it is a normal unregistered purchase, but because it is a separately notified Section 9(4) case.

Old β‚Ή5,000 Per Day Rule

The old idea that RCM applies if purchases from unregistered persons exceed β‚Ή5,000 per day is not the current rule for normal purchases.

That old proviso linked to Section 9(4) has been omitted.

Simple Answer

  • Normal purchase from unregistered dealer: No RCM
  • Notified special cases only: RCM applies

One-Line Exam Answer

Reverse charge is not applicable on ordinary purchases from unregistered dealers in 2026; it applies only to notified cases under Section 9(4).

Very Simple Examples

  • Buy stationery from unregistered shop β†’ No RCM
  • Pay commercial shop rent to unregistered landlord as a normal registered taxpayer β†’ RCM applies
  • Promoter receiving notified inputs/services from unregistered suppliers β†’ RCM may apply

1. RCM on Services (Most Important – Sec 9(3))

Service Who Pays GST
Advocate (Legal services) Receiver
GTA (Goods Transport Agency) Receiver (if 5% option)
Sponsorship services Receiver
Director services to company Company
Insurance agent to company Company
Recovery agent to bank/NBFC Bank / NBFC
Author (writer, artist etc.) Publisher (in some cases)

2. RCM on Unregistered Supplier (Sec 9(4))

Applies only in specific notified cases, not as a general rule.

Confirmed Cases RCM Status
Commercial rent from unregistered landlord Applicable
Promoter purchases from unregistered persons Applicable in notified cases
❗ Important Correction: This is not a general rule for all purchases from unregistered persons.

3. RCM on Goods (Limited – Not Common)

Notified Goods Who Pays
Cashew nuts (raw) Buyer
Tobacco leaves Buyer
Lottery Distributor
Scrap (metal waste – from certain suppliers) Buyer

4. Import of Services

  • If service is received from outside India, GST is paid by Indian receiver under RCM
  • ITC is allowed if used for business purpose

5. E-Commerce Operator (Sec 9(5))

This is a special case. It is not exactly pure RCM, but the concept is similar.

Service Who Pays
Cab services (Ola/Uber) Platform
Hotel booking (unregistered hotel via app) Platform

Important Corrections

  • GTA: 5% β†’ RCM applies
  • GTA: 12% / 18% forward charge β†’ No RCM
  • Scrap: RCM applies only in specific conditions, not in all scrap cases
  • E-commerce: Covered under Sec 9(5), not pure RCM

Final Rule (Clear)

βœ” RCM applies only in notified cases
❌ Unregistered purchase does not automatically mean RCM

Easy Memory Trick

  • 1. Advocate
  • 2. GTA
  • 3. Director
  • 4. Rent from unregistered landlord
  • 5. Import of services

One-Line Exam Answer

RCM is applicable only on notified services and goods under Sections 9(3) and 9(4), not on normal purchases.

Caution

Some older GST FAQs still circulating online reflect the old position. For 2026 understanding, rely on the amended Section 9(4) and specific notifications.

GST ON FREIGHT, PACKING, LOADING/UNLOADING & GTA

1. GST Treatment on Freight, Packing, Loading/Unloading & Incidental Charges

As per Section 15 of the CGST Act, 2017, if freight, packing, loading/unloading, insurance, or other incidental charges are charged by the supplier in the same invoice along with goods, then these charges form part of the value of supply.

If these charges are included in the taxable invoice for goods, they become part of the composite supply.

2. Composite Supply Meaning

If the principal supply is supply of goods, then extra charges like freight, packing, loading/unloading, and insurance are treated as part of that goods supply.

GST rate on these extra charges will be the same as the GST rate on the main goods.

3. GST Rate Applicability

When freight, packing, and other incidental charges are shown on the same invoice as goods, the GST rate applicable to these charges will be the same as the rate applicable to the goods.

Example:

If goods attract 18% GST and freight/packing/loading charges are shown on the same invoice, then 18% GST will also apply on those charges.

4. Goods Booked on F.O.R. Basis

F.O.R. (Free on Road/Rail) basis means the supplier remains responsible for delivering the goods to the buyer’s location, and the freight cost is included in the invoice.

In F.O.R. basis supplies, the same GST rate as applicable to the goods applies on the entire invoice value, including freight and incidental charges.

5. Separate Third-Party Freight (GTA)

If the buyer directly pays a transporter (GTA) separately, or the transporter raises a separate bill, then GST on freight will be governed by transportation-specific rules.

  • βœ” If GTA issues separate bill, GST applies under GTA rules
  • βœ” 5% under RCM (most common)
  • βœ” 12% under forward charge (if GTA opts and conditions are met)

Important Clarification:

Under 5% β†’ ITC not allowed to GTA

Under 12% β†’ ITC allowed to GTA

6. GST on GTA (Goods Transport Agency)

6.1 5% GST under RCM (Reverse Charge Mechanism)

  • GTA does not pay GST
  • Recipient pays GST to Government
  • Rate = 5% GST (2.5% CGST + 2.5% SGST)

Who Pays GST under 5% RCM?

RCM applies when GTA services are provided to specified persons such as:

  • Factory registered under the Factories Act
  • Registered person under GST
  • Company / LLP
  • Partnership firm
  • Society

ITC under 5% RCM

  • ❌ GTA cannot take ITC
  • βœ” Recipient can take ITC if eligible

Practical Example:

Freight = β‚Ή10,000

GST @ 5% = β‚Ή500

Buyer pays β‚Ή500 directly to Government, not to transporter.

7. 12% GST under Forward Charge

  • GTA itself charges GST in the invoice
  • GTA pays GST to Government
  • Rate = 12% GST (6% CGST + 6% SGST)

Condition

  • GTA must opt for forward charge
  • Option is taken at the beginning of the financial year

Who Pays GST?

  • GTA collects GST from customer
  • Then deposits it to Government

ITC under 12% Forward Charge

  • βœ” GTA can claim ITC on expenses
  • βœ” Recipient can also claim ITC

Practical Example:

Freight = β‚Ή10,000

GST @ 12% = β‚Ή1,200

Buyer pays β‚Ή11,200 to transporter, and transporter deposits GST.

8. Key Difference – 5% RCM vs 12% Forward Charge

Point 5% RCM 12% Forward Charge
Who pays GST Recipient GTA
GST Rate 5% 12%
ITC for GTA ❌ Not allowed βœ” Allowed
ITC for Customer βœ” Allowed βœ” Allowed
Invoice GST shown ❌ No βœ” Yes

9. Quick Final Rule

If freight, packing, loading/unloading, insurance, and incidental charges are included in the same invoice with goods, GST rate of the principal goods applies on all these charges.
Same invoice with goods = Same GST rate as goods

10. One-Line Exam Answer

Freight, packing, loading/unloading, insurance and other incidental charges, when charged in the same invoice with goods, form part of the value of composite supply and attract GST at the same rate as the principal supply.
