Practical Maritime Tax Issues — Part 4: When Can Wrongfully Withheld or Deducted Tax Amounts Be Reclaimed?

In international maritime transactions, amounts may sometimes be deducted — or withheld — as taxes or tax-related liabilities during financial settlements involving shipping services, container-related activities, or local agents.

The first question that may arise is whether the deduction or withholding was legally justified in the first place. This is particularly relevant where the underlying transaction involves a foreign shipping company, an international carriage operation, or a service connected with vessels calling at ports.

In some cases, a later examination may reveal that the service in question was not subject to tax under the applicable law, that a Double Taxation Agreement provides protection from the imposition of the tax, that the foreign company did not have a sufficient taxable presence in the jurisdiction, or that the legal characterization of the transaction was incorrect from the outset.

What initially appears to be a routine accounting entry or deduction may, in practice, turn into a substantive tax dispute involving the recovery of improperly withheld amounts, determination of the party legally responsible for the tax liability, interpretation of domestic tax law and applicable treaty provisions, and assessment of whether the original tax treatment was applied correctly.

The complexity of these issues is often compounded by the cross-border nature of maritime transactions, the involvement of multiple parties across different jurisdictions, and the interaction between local tax rules and international treaty obligations.

Where the legal basis for the deduction or withholding is uncertain, or where the amounts involved are significant, the transaction may warrant a detailed review — involving the underlying contracts, invoices, agency arrangements, payment records, and the relevant legal and treaty framework — to determine whether the amount can be challenged and reclaimed where the law permits.

It is important to address these issues promptly, as limitation periods, procedural requirements, and the availability of administrative remedies may affect the ability to pursue recovery in certain jurisdictions.
