TL;DR: A gross-up clause requires the payor to increase a payment so that, after deduction of any withholding tax, the recipient receives the full amount it was originally entitled to. Without a gross-up, a withholding tax obligation reduces the recipient's net receipts below the agreed contract price. The clause shifts the economic burden of withholding tax from the recipient to the payor, and it is standard in cross-border lending, intercompany agreements, and international service contracts. Key drafting variables include the scope of taxes covered, the interaction with tax treaty benefits, FATCA and CRS compliance, change-in-law triggers, the distinction between gross-up and tax indemnity, and exceptions for taxes attributable to the recipient's own status or failure to provide required documentation.

‍

What Is a Gross-Up Clause?

A gross-up clause is a contractual provision that requires the party making a payment (the "payor") to increase the amount paid so that the net sum received by the payee, after deduction or withholding of any applicable taxes, equals the amount that the payee would have received had no such deduction or withholding been required. In practical terms, if a borrower owes $100 in interest and the jurisdiction imposes a 20% withholding tax, the borrower must pay $125 so that, after the $25 withholding, the lender receives $100 net.

Withholding taxes arise when a jurisdiction requires the payor to deduct a percentage of certain payments (typically interest, royalties, dividends, management fees, or service fees) and remit the withheld amount to the local tax authority. The obligation to withhold falls on the payor as a matter of law, but the economic burden falls on the payee unless the contract provides otherwise. A gross-up clause reallocates that economic burden back to the payor.

Gross-up clauses are distinct from tax indemnities, though the two are often found together. A gross-up addresses the specific mechanics of withholding tax by requiring an increased payment at the time of each payment. A tax indemnity is broader: it requires the payor to hold the payee harmless against any tax liability arising from the transaction, including taxes assessed after the payment date, taxes on the gross-up amount itself (the "gross-up on the gross-up"), and taxes that arise from regulatory changes or treaty reclassifications. Many contracts include both provisions, with the gross-up addressing routine withholding and the indemnity addressing unexpected or retrospective tax liabilities.

Why It Matters

Preserves the economic bargain: Parties negotiate payment amounts based on an expected net return. If withholding tax reduces the recipient's yield, the pricing no longer reflects the agreed deal. Gross-up ensures that the lender, licensor, or service provider receives the return it priced into the transaction.
Essential for cross-border lending: In syndicated loan facilities, bonds, and bilateral credit agreements, lenders price their return based on SOFR/EURIBOR plus a margin. A withholding tax that reduces the net interest received effectively cuts the lender's margin or turns it negative. The Loan Market Association (LMA) and Loan Syndications and Trading Association (LSTA) standard forms both include mandatory gross-up provisions.
Interacts with treaty networks and regulatory regimes: Withholding tax rates depend on domestic law, bilateral tax treaties, and multilateral instruments (e.g., the OECD Multilateral Convention). A gross-up clause must account for the possibility that a treaty reduces or eliminates withholding, and allocate the obligation to claim treaty benefits.
FATCA and CRS compliance layer: The US Foreign Account Tax Compliance Act (FATCA) and the OECD Common Reporting Standard (CRS) impose additional withholding obligations on payments to non-compliant recipients. Gross-up clauses must address whether FATCA/CRS withholding is covered or excluded, which has become a heavily negotiated point since FATCA's implementation.
Change-in-law risk allocation: Tax laws change. A transaction structured to be withholding-tax-free today may attract withholding after a legislative amendment or treaty renegotiation. Change-in-law gross-up triggers allocate the risk of such changes between the parties.

Key Elements of a Well-Drafted Gross-Up Clause

Definition of covered taxes: Specify which taxes trigger the gross-up obligation. The broadest formulation covers "all taxes, duties, imposts, or levies of whatever nature" imposed by any jurisdiction on the payment. Narrower formulations cover only withholding taxes or income taxes imposed by the payor's jurisdiction. Exclude taxes on the payee's overall income (as opposed to taxes on the specific payment), which are the payee's own responsibility.
Gross-up formula: State the mathematical requirement clearly: the payor must pay such additional amount as ensures that the net amount received by the payee, after all required deductions and withholdings (including any deduction or withholding on the additional amount itself), equals the amount that would have been received absent the deduction. The "gross-up on the gross-up" is often overlooked but is mathematically necessary to achieve true indemnification.
Treaty benefit and credit obligations: Address the payee's obligation to claim available treaty benefits (reduced rates or exemptions) and to provide the payor with the documentation required to apply the reduced rate at source (e.g., IRS Forms W-8BEN, W-8BEN-E, or equivalent certificates of residence). Specify that the gross-up does not apply to the extent the payee fails to provide required documentation or is ineligible for treaty benefits due to its own circumstances.
FATCA/CRS carve-out: Address whether the gross-up applies to withholding imposed under FATCA (Sections 1471-1474 of the US Internal Revenue Code) or under local CRS implementing legislation. In the syndicated loan market, the prevailing approach (LMA and LSTA standard forms) is to exclude FATCA withholding from the gross-up obligation, on the basis that FATCA compliance is within the payee's control.
Change-in-law trigger: Define whether the gross-up obligation applies only to withholding taxes in effect at the date of the contract or extends to new or increased withholding imposed after the contract date. Change-in-law gross-up triggers are standard in long-term lending and infrastructure finance, where the transaction may span decades.
Exceptions and limitations: Common exceptions include taxes imposed because the payee is a resident of the payor's jurisdiction (nexus-based exclusion), taxes that would not have been imposed but for the payee's failure to comply with documentation requirements, taxes imposed under FATCA/CRS, and taxes that the payee could have avoided by lending through a different branch or office.
Tax credit for withheld amounts: If the payee obtains a tax credit in its home jurisdiction for the withheld amount, should the gross-up be reduced or refunded? Some clauses require the payee to use reasonable efforts to claim available credits and to reimburse the payor for any credit actually received, though this is uncommon in the loan market.
Relationship to tax indemnity: Clarify the boundary between the gross-up (which addresses withholding at the time of payment) and any separate tax indemnity (which may address retrospective assessments, secondary tax liabilities, or taxes on the gross-up amount). Avoid overlap that could result in double recovery.

Market Position & Benchmarks

Where Does Your Clause Fall?

Payee-favorable (lender/licensor): Broad definition of covered taxes including all present and future taxes of any nature. Full gross-up on the gross-up. No FATCA exclusion (or FATCA exclusion limited to non-participating FFIs). Change-in-law trigger covering any increase in withholding after the contract date. No obligation to mitigate by lending through a different branch. No obligation to refund tax credits obtained by the payee.
Market standard (LMA/LSTA syndicated loan): Gross-up covers all withholding taxes except FATCA withholding. Change-in-law trigger included. Payee must provide treaty documentation. No obligation to mitigate by changing lending office (but an optional "mitigation" clause may require reasonable efforts). Tax credit repayment clause included but subject to the payee's discretion to claim credits.
Payor-favorable (borrower): Narrow definition covering only withholding taxes in the payor's jurisdiction. FATCA exclusion broadly drafted to cover all FATCA-related withholding. Payee required to use reasonable efforts to claim treaty benefits and to mitigate by lending through a branch in a jurisdiction with a favorable treaty. Gross-up obligation ceases if the payee fails to provide required documentation. Tax credits must be refunded to the payor. Cap on aggregate gross-up payments.

Market Data

Gross-up clauses appear in virtually 100% of cross-border syndicated loan facilities, as both the LMA (Europe) and LSTA (US) standard forms include them as a default provision.
Approximately 85-90% of syndicated loan facilities exclude FATCA withholding from the gross-up obligation, following the LMA/LSTA recommended approach.
In cross-border IP licensing and technology transfer agreements, gross-up clauses appear in approximately 70-75% of agreements, but the scope and exceptions vary significantly by sector and jurisdiction pair.
Change-in-law gross-up triggers are present in approximately 95% of project finance loan agreements and infrastructure bonds, reflecting the long tenor of these instruments (typically 15-25 years).
The average cost impact of a gross-up obligation on a cross-border loan into a 20% withholding jurisdiction is 25% of the interest payment (the mathematical gross-up required to deliver 100% of the contractual interest after a 20% deduction).

Sample Language by Position

Payee-favorable: "All payments by the Borrower under this Agreement shall be made free and clear of and without deduction or withholding for or on account of any Taxes. If the Borrower is required by law to make any such deduction or withholding, the amount payable by the Borrower shall be increased to the extent necessary to ensure that, after making all required deductions and withholdings (including deductions and withholdings applicable to additional amounts payable under this paragraph), the Lender receives an amount equal to the amount it would have received had no such deduction or withholding been required."

Market standard (LMA-based): "If a Tax Deduction is required by law to be made by the Borrower, the amount of the payment due from the Borrower shall be increased to an amount which (after making any Tax Deduction) leaves an amount equal to the payment which would have been due if no Tax Deduction had been required. The Borrower shall not be required to make any increased payment in respect of a Tax Deduction for or on account of (a) any tax imposed under FATCA, or (b) any tax to the extent that such tax would not have been imposed but for the Lender's failure to comply with its obligations under Clause [Treaty Documentation]."

Payor-favorable: "If the Borrower is required to deduct or withhold Tax from any payment, the Borrower shall increase the payment only to the extent necessary to ensure that the Lender receives the net amount it would have received absent the deduction, provided that the Borrower shall not be obligated to gross up any payment to the extent that (a) the relevant Tax is imposed under FATCA or any equivalent regime, (b) the Lender has failed to provide a valid tax residency certificate or treaty relief form within the time required, (c) the Lender could have avoided the Tax by lending through a branch in a jurisdiction with a more favorable treaty, or (d) the relevant Tax is a Tax on the Lender's overall net income. The Lender shall use reasonable efforts to claim any available tax credit in respect of the Tax withheld and shall promptly refund to the Borrower any amount by which such credit reduces the Lender's tax liability."

‍

Example Clause Language

Cross-border loan agreement: "All payments of interest by the Borrower to the Lender under this Agreement shall be made without deduction or withholding for or on account of any Tax unless such deduction or withholding is required by applicable law. If any such deduction or withholding is required, the Borrower shall pay to the Lender such additional amount (a 'Tax Gross-Up Amount') as will result in the Lender receiving a net amount equal to the full amount which it would have received had no such deduction or withholding been made. The Borrower shall promptly deliver to the Lender official receipts or other evidence reasonably satisfactory to the Lender evidencing payment of the amounts so withheld to the relevant taxing authority. For the avoidance of doubt, the obligation to pay Tax Gross-Up Amounts shall extend to any Tax imposed on the Tax Gross-Up Amount itself."

Technology license agreement: "All royalty payments and other fees payable by the Licensee under this Agreement are expressed exclusive of any withholding or deduction for Tax. If the Licensee is required by the laws of any jurisdiction to deduct or withhold any Tax from any payment, the Licensee shall (a) make the deduction or withholding and pay the amount withheld to the relevant authority in accordance with applicable law, (b) increase the payment to the Licensor so that the Licensor receives, free and clear of any such deduction or withholding, the full amount stated in this Agreement, and (c) furnish to the Licensor, within thirty (30) days of making the payment, the original or certified copy of a receipt evidencing payment to the taxing authority. The Licensee's obligation under this Clause shall not apply to any Tax that the Licensor could have avoided by providing a valid certificate of tax residence or treaty benefit claim form, provided the Licensee has given the Licensor at least sixty (60) days' prior notice of the documentation required."

Intercompany services agreement: "Each payment under this Agreement shall be made in full without any set-off, counterclaim, deduction, or withholding (other than any deduction or withholding of Tax required by law). If a deduction or withholding of Tax is required by law, the paying entity shall gross up the payment so that the receiving entity receives an amount equal to the payment that would otherwise have been due. The parties acknowledge that the services under this Agreement are intended to qualify for the benefit of the [relevant treaty] and agree to cooperate in completing and filing any documentation necessary to apply the reduced rate of withholding provided by that treaty. If a change in law after the date of this Agreement results in a new or increased withholding tax on payments under this Agreement, the parties shall negotiate in good faith to restructure the payment arrangements to minimize the withholding tax impact, and pending such restructuring, the gross-up obligation under this Clause shall apply."

Common Contract Types

Syndicated and bilateral loan agreements. Gross-up is a standard provision in virtually all cross-border lending facilities, protecting lenders from withholding tax on interest payments. LMA and LSTA model forms include detailed gross-up mechanics.
Bond and note indentures. Issuers of cross-border debt securities include gross-up provisions to maintain the attractiveness of the securities to international investors. Tax call provisions allow the issuer to redeem the bonds if a change in law triggers gross-up obligations.
Technology and IP license agreements. Cross-border royalty payments are commonly subject to withholding tax. Licensors typically require gross-up to protect their royalty yield, particularly when the licensee is in a jurisdiction with high withholding rates and limited treaty network.
Intercompany and transfer pricing agreements. Multinational groups structure intercompany payments (management fees, shared services charges, royalties) with gross-up provisions to ensure that the economic allocation of income among group entities reflects the transfer pricing policy.
Joint venture and shareholders' agreements. Dividend and distribution payments to foreign joint venture partners may attract withholding tax. Gross-up provisions protect the foreign partner's expected return on investment.
Project finance and infrastructure concession agreements. Long-tenor debt in project finance transactions requires robust gross-up and change-in-law provisions to protect lender returns over the project's life, which may span 15-30 years.
Service agreements with cross-border payment flows. Management consulting, technical services, and advisory agreements involving payments from high-withholding jurisdictions commonly include gross-up to protect the service provider's fee.

Negotiation Playbook

Key Drafting Notes

Address the "gross-up on the gross-up": The additional amount paid as gross-up is itself a payment that may be subject to withholding. If the clause does not explicitly require the payor to gross up the gross-up amount, the payee still receives less than the intended net amount. The formula should state that the increase covers deductions on "additional amounts payable under this paragraph."
Coordinate with the FATCA provisions: The FATCA carve-out in the gross-up clause must align with the FATCA representations and compliance obligations elsewhere in the agreement. If the payee represents that it is a participating FFI, the FATCA exclusion is less concerning. If the payee's FATCA status is uncertain, the scope of the exclusion becomes heavily negotiated.
Specify documentation timing: Require the payee to deliver treaty documentation (W-8 forms, certificates of residence, treaty benefit claims) within a specified period before the first payment date, and to update documentation when it expires or the payee's circumstances change. Tie the gross-up obligation to compliance with these requirements.
Consider the cost of gross-up in pricing: The payor should model the gross-up cost when evaluating the transaction's economics. A 20% withholding rate with a gross-up obligation effectively increases the cost of each interest payment by 25%. This cost should be factored into the overall pricing or used as leverage to negotiate a narrower gross-up scope.
Draft change-in-law triggers carefully: A broad change-in-law trigger ("any change in law or its interpretation after the date hereof") may capture changes that were foreseeable or already in the legislative pipeline. Consider whether the trigger should be limited to changes that were not reasonably foreseeable, or whether it should cover all changes regardless of foreseeability.

Common Pitfalls

Conflating gross-up with tax indemnity: A gross-up addresses withholding at the time of payment. A tax indemnity addresses broader tax liabilities, including retrospective assessments and secondary liabilities. If the contract includes only a gross-up but not an indemnity, the payee may be unprotected against a tax authority's retrospective assessment of additional withholding. If the contract includes both without clear delineation, the payee may argue for double recovery.
Ignoring the payee's ability to mitigate: In some cases, the payee can eliminate or reduce withholding by lending through a different branch, restructuring the payment flow, or providing specific documentation. A gross-up clause that does not require reasonable mitigation efforts incentivizes the payee to accept the withholding (since it is made whole by the gross-up) rather than taking steps to avoid it.
Ambiguous FATCA exclusion: The scope of the FATCA exclusion is a frequent source of disputes. Does it cover only withholding imposed under Sections 1471-1474 of the IRC, or does it extend to "FATCA-like" withholding imposed under local implementing legislation (e.g., UK FATCA, Australian FATCA)? Specify the scope precisely.
No mechanism for treaty rate changes: If a bilateral tax treaty is renegotiated and the withholding rate changes (up or down), the gross-up clause should reflect the new rate. But if the clause references a specific treaty rate or percentage, it may not automatically adjust. Use dynamic language that references "the applicable rate under the relevant treaty" rather than a fixed percentage.
Overlooking stamp duty and similar transaction taxes: Some jurisdictions impose stamp duty, registration tax, or financial transaction tax on loan agreements or payments. These are not withholding taxes but may reduce the payee's net receipts. Determine whether the gross-up clause should cover these taxes or whether they should be addressed separately.

‍

Jurisdiction Notes

United States: The US imposes a 30% withholding tax on "fixed or determinable annual or periodical" (FDAP) income paid to non-US persons, including interest, royalties, and certain service fees (IRC Sections 1441-1442). The rate may be reduced or eliminated by an applicable income tax treaty. The payee must provide a valid Form W-8 (W-8BEN, W-8BEN-E, or W-8ECI) to claim treaty benefits at source. FATCA (Sections 1471-1474) imposes an additional 30% withholding on "withholdable payments" to non-participating foreign financial institutions (FFIs) and non-compliant account holders. US-source interest on portfolio debt obligations may qualify for the portfolio interest exemption (IRC Section 881(c)), which eliminates withholding without a treaty, but this exemption is not available for bank loans, related-party debt, or contingent interest.

United Kingdom: The UK imposes withholding tax on interest payments at a statutory rate of 20% (Income Tax Act 2007, Section 874), subject to reduction under applicable tax treaties. There is no withholding on royalty payments within the UK domestic regime, but withholding may apply under the EU Interest and Royalties Directive as retained in UK law. The UK has an extensive treaty network that typically reduces withholding on interest to 0-10%. HMRC Direction under Section 931 ITA 2007 can authorize payment of interest without deduction where a treaty applies. The UK enacted FATCA and CRS implementing legislation through the International Tax Compliance Regulations 2015.

Civil law jurisdictions and emerging markets: Many civil law jurisdictions impose withholding taxes at rates ranging from 10% to 35% on cross-border interest and royalty payments. In emerging markets (Brazil, India, Indonesia, Argentina), withholding rates tend to be higher and treaty networks narrower, making gross-up provisions more economically significant. India, for example, imposes withholding on a broad range of payments to non-residents (including technical services under Section 195 of the Income Tax Act, 1961) and has been aggressive in expanding the scope of payments subject to withholding. Brazil's IOF (tax on financial operations) and IRRF (withholding income tax) create a complex layering of taxes on cross-border payments that requires careful drafting of gross-up provisions.
