If your enterprise operates branch offices, warehouses, or retail units across multiple states under a single PAN, your corporate headquarters routinely incurs expenditures that benefit the entire organization. Centralized vendor services such as cloud hosting, statutory audit, and ERP subscriptions arrive at the head office, while centralized staff teams handle accounting, executive leadership, legal review, and human resources for all regional units.
Before recent statutory amendments, many finance teams handled both third-party vendor expenses and internal management support using regular outward tax invoices issued under Section 31, commonly known as cross charge. That blended approach is now an audit violation. Following the substitution of Section 20 by the Finance Act 2024, common vendor services must flow exclusively through an Input Service Distributor registration, leaving cross charge strictly for internally generated corporate functions.
Distinct persons and the concept of cross charge
Under Section 25(4) of the CGST Act, a person who has obtained or is required to obtain more than one registration, whether in one State or Union territory or more than one State or Union territory, is treated as distinct persons in respect of each registration. A company operating under a single PAN with registrations in Maharashtra, Karnataka, and Delhi represents three separate taxable persons under GST law.
This distinct person classification triggers the statutory fiction in Schedule I of the CGST Act. Under paragraph 2 of Schedule I, supplies of goods or services between related persons or between distinct persons as specified in Section 25, when made in the course or furtherance of business, qualify as supplies even when made without consideration.
When employees at a corporate head office provide executive strategy, treasury functions, central marketing design, or IT troubleshooting to regional operating branches, a supply of service takes place under Schedule I. Because distinct persons are involved, the supplying office must issue a regular tax invoice under Section 31 and report the transaction in its normal Form GSTR-1 and Form GSTR-3B. This mechanism is known as cross charge.
The statutory boundary: when cross charge ends and ISD begins
The core distinction between cross charge and Input Service Distributor lies in the origin of the service. Cross charge governs internally generated services produced by the company's own workforce and infrastructure. In contrast, the ISD mechanism governs third-party input services procured from external suppliers.
Under Section 20(1) of the CGST Act as substituted by the Finance Act 2024, any office of a supplier that receives tax invoices towards the receipt of input services for or on behalf of distinct persons referred to in Section 25 must register mandatorily as an Input Service Distributor under Section 24(viii). This requirement was brought into force with effect from 1 April 2025 vide Notification 16/2024-Central Tax.
A head office cannot choose to absorb external vendor invoices on its regular operating GSTIN and cross charge those vendor costs out to branch offices. To review the dedicated procedural requirements for ISD filing, read our detailed guide on mandatory ISD registration and Rule 39 guidelines.
Notice risk: If your head office uses outward cross charge tax invoices to pass on input tax credit for third-party IT licenses, national marketing campaigns, or corporate consultancy contracts, departmental auditors can reject the ITC claimed by recipient branches under Section 20, while demanding output tax or reversal from the head office with interest under Section 50.
Valuation of internal cross charge under Rule 28 and Circular 199
Valuing internally generated services between distinct persons was historically a point of dispute during GST audits. Tax authorities frequently questioned whether head offices were properly allocating corporate employee payroll into the cross charge invoice base.
The Central Board of Indirect Taxes and Customs resolved this uncertainty by issuing CBIC Circular No. 199/11/2023-GST on 17 July 2023. In paragraph 4 of the circular, the Board addressed the valuation of internally generated services provided by a head office to branch offices.
The circular established two fundamental valuation principles for internal corporate services:
- Exclusion of employee salary costs: Under Entry 1 of Schedule III of the CGST Act, services by an employee to the employer in the course of employment are neither a supply of goods nor a supply of services. Circular 199/11/2023-GST explicitly clarifies that a head office is not mandatorily required to include employee salary costs when computing the taxable value of internally generated services supplied to branch offices.
- Invoice value deemed as open market value: Under the second proviso to Rule 28 of the CGST Rules, where the recipient distinct person is eligible for full input tax credit, the value declared in the invoice is deemed to be the open market value of the services. Paragraph 4.4 of Circular 199 confirms that if the head office issues an invoice for any value, or even if the head office does not issue an invoice and treats the value as Nil, that value is deemed to be the open market value, provided the recipient branch can claim full credit under Section 16 input tax credit rules.
“in respect of internally generated services provided by the HO to BOs, the cost of salary which is not required to be included in the value of supply of such services by the HO to the BOs... in cases where full input tax credit is available to a recipient, if HO has not issued a tax invoice to the BO in respect of any particular services being provided by HO to the said BO, the value of such services may be deemed to be declared as Nil by the HO to the said BO, and may be deemed as open market value in terms of second proviso to rule 28” CBIC Circular No. 199/11/2023-GST, paragraph 4.3 and 4.4
Exempt supply caution: The relief under the second proviso to Rule 28 applies only when the recipient branch is entitled to full input tax credit. If your branch office engages in exempt supplies, such as healthcare, educational services, or alcohol trading, it is not eligible for full credit. In that situation, the open market value must be computed using cost plus ten percent under Rule 30 or reasonable means under Rule 31, including internal overheads.
Comparison between cross charge and input service distributor
To help finance teams establish correct standard operating procedures, the following operational matrix contrasts cross charge with the ISD mechanism:
| Compliance parameter | Cross charge mechanism | Input Service Distributor (ISD) |
|---|---|---|
| Governing provisions | Section 25(4), Schedule I para 2, Rule 28 | Section 20, Section 24(viii), Rule 39 |
| Nature of service covered | Internally generated services by head office staff | Common input services from third-party vendors |
| Separate registration needed | No, uses regular operating GSTIN of head office | Yes, mandatory dedicated 15-digit ISD GSTIN |
| Document issued | Tax invoice issued under Section 31 | ISD invoice or credit note under Rule 54(1) |
| Reporting return | Form GSTR-1 and Form GSTR-3B | Form GSTR-6 filed monthly by the 13th |
| Recipient auto-population | Table 4(A)(5) All other ITC in GSTR-2B | Table 4(A)(4) Inward supplies from ISD in GSTR-2B |
| Reverse charge services | Discharged on regular GSTIN in cash | Paid by regular GSTIN, passed to ISD via Rule 54(1A) |
Step-by-step workflow for head office accountants
Accountants handling corporate compliance across several states should adopt a systematic four-step procedure at the end of each tax period:
- Segregate inward procurement: Review all invoices received at corporate headquarters. Invoices representing third-party input services consumed by multiple locations (such as enterprise software licenses, national marketing agencies, or legal counsel) must be addressed to the dedicated ISD GSTIN.
- Distribute credit in Form GSTR-6: By the 13th of each month, compile the turnover figures of operational recipient branches from the preceding financial year. Distribute the eligible and ineligible tax credit pro rata under Rule 39 and file Form GSTR-6.
- Assess internally generated services: Review centralized head office support functions. If recipient branch offices make only taxable supplies and enjoy full ITC, evaluate whether to issue cross charge tax invoices using the valuation flexibility permitted under Circular 199/11/2023-GST and Rule 28. If cross charge invoices are issued, include them in the regular head office Form GSTR-1 by the 11th.
- Verify recipient branch credits: Branch accountants must verify that distributed ISD credits appear in Table 4(A)(4) of their respective GSTR-2B statements, while cross charge invoices appear in Table 4(A)(5). Reconcile these records with regional books before submitting Form GSTR-3B by the 20th. For multi-state management steps, consult our manual on GSTR-2B reconciliation for multiple GSTINs.
Worked rupee example: enterprise software versus corporate management fees
Consider Zenith Enterprise Private Limited, a company with corporate headquarters in Mumbai holding two GSTINs: a regular manufacturing GSTIN (27AAAAA0000A1Z1) and an ISD GSTIN (27AAAAA0000A1Z5). Zenith operates two manufacturing branches: one in Pune, Maharashtra (covered under the Mumbai regular GSTIN) and one in Bengaluru, Karnataka (29AAAAA0000A1Z2).
Both operating units make 100 percent taxable outward supplies and are entitled to full input tax credit. The turnover ratio of the two units in the preceding financial year was 60 percent for Maharashtra and 40 percent for Karnataka.
In September 2026, the corporate office handled two distinct transactions:
- Third-party vendor transaction: An annual cloud software subscription invoice received from an external vendor in Bengaluru for ₹5,00,000 plus 18 percent IGST of ₹90,000, billed to Zenith's ISD GSTIN.
- Internally generated support transaction: Corporate management, central treasury, and IT engineering provided by Mumbai head office employees to the Karnataka unit. The company decides to issue a cross charge management fee invoice of ₹2,00,000 plus 18 percent IGST of ₹36,000 from the Mumbai regular GSTIN to the Karnataka branch GSTIN.
| Transaction item | Mechanism used | Supplying GSTIN | Recipient branch | Tax head | Tax amount | Recipient 2B table |
|---|---|---|---|---|---|---|
| Cloud software (60% share) | ISD distribution | 27AAAAA0000A1Z5 | Maharashtra (Pune) | CGST + SGST | ₹54,000 | Table 4(A)(4) |
| Cloud software (40% share) | ISD distribution | 27AAAAA0000A1Z5 | Karnataka (Bengaluru) | IGST | ₹36,000 | Table 4(A)(4) |
| Corporate management fee | Internal cross charge | 27AAAAA0000A1Z1 | Karnataka (Bengaluru) | IGST | ₹36,000 | Table 4(A)(5) |
| Total ITC available to Karnataka | Combined | Both GSTINs | Karnataka unit | IGST total | ₹72,000 | Full credit |
Arithmetic breakdown for verification: The third-party cloud software carries total IGST of ₹90,000. Under Rule 39, Maharashtra's 60 percent share equals ₹54,000. Because the ISD and the Pune unit are in the same state, this ₹54,000 is distributed as CGST ₹27,000 and SGST ₹27,000. Karnataka's 40 percent share equals ₹36,000 and is distributed as IGST. For the management fee, the tax invoice issued by the Mumbai operating GSTIN charges 18 percent IGST on ₹2,00,000, resulting in ₹36,000 of outward tax payable by Mumbai and eligible credit for Karnataka. The Karnataka unit receives ₹72,000 total IGST across both mechanisms.
Common compliance mistakes to avoid
Finance teams frequently encounter compliance errors when managing multi-unit corporate accounts:
Common mistake: Failing to obtain a separate ISD registration. Many businesses assume that because their corporate head office already holds a regular GST registration, it can distribute vendor ITC by adding an ISD endorsement. Under GST rules, an ISD requires a separate and distinct registration application on the portal, resulting in its own dedicated 15-digit GSTIN.
- Distributing input goods through ISD: Section 20 authorizes an Input Service Distributor to distribute credit on input services only. Tangible inputs such as raw materials, spare parts, or capital goods like computers cannot be distributed through Form GSTR-6. If capital goods are transferred between branches, the supplying unit must issue a regular tax invoice under Section 31.
- Ignoring branch eligibility when valuing cross charge: Assuming that the second proviso to Rule 28 allows nominal or Nil valuation across all branches without verifying their outward supply profile. If a branch makes exempt sales, issuing a Nil invoice creates liability under audit.
- Misreporting ISD credit in GSTR-3B: Branch accountants occasionally lump ISD credits into Table 4(A)(5) All other ITC rather than Table 4(A)(4). Mismatching system auto-drafted totals can trigger automated verification flags during scrutiny.

Frequently asked questions
What is the difference between cross charge and Input Service Distributor under GST?
Cross charge applies to internally generated services supplied by a head office or one branch to another distinct person under Section 25(4) and Schedule I. Input Service Distributor applies exclusively to distributing input tax credit on common third-party vendor services procured centrally, which is mandatory under substituted Section 20.
Can a head office still use cross charge invoices to distribute common vendor ITC?
No. Following the amendment of Section 20 of the CGST Act by the Finance Act 2024, notified with effect from 1 April 2025 vide Notification 16/2024-Central Tax, common input services procured from third-party vendors must be distributed through mandatory ISD registration. The voluntary option previously outlined in CBIC Circular 199/11/2023-GST no longer applies to third-party vendor bills.
Must employee salary costs be included when calculating internal cross charge?
No. Paragraph 4 of CBIC Circular 199/11/2023-GST clarifies that head offices are not mandatorily required to include employee salary costs in cross charge invoices. In addition, under the second proviso to Rule 28, if the recipient branch is entitled to full input tax credit, any invoice value declared by the head office, including a nominal or Nil value, is deemed to be open market value.
Which return forms are used for cross charge and ISD?
Cross charge transactions are reported by the supplying office in regular outward supplies via Form GSTR-1 and GSTR-3B. An Input Service Distributor files Form GSTR-6 monthly by the 13th, which auto-populates distributed credit directly into Table 4(A)(4) of each recipient branch's GSTR-2B.
