Whether you need someone to run your tax filings every month or a defensible answer on a single transaction, the goal is the same: tax positions that hold up when the tax authority looks at them. Most FDI companies need both, ongoing compliance and advice before the decisions that carry risk.

Background

FDI subsidiaries regularly face transactions their in-house accountant rarely sees: royalties paid to the parent, technical services received from abroad, management costs allocated within the group, or profits repatriated to shareholders.

Each of these engages a distinct set of rules, whether foreign contractor tax, transfer pricing documentation or the conditions attached to profit remittance. Getting it wrong is not immediately visible. It typically surfaces during an inspection several years later, by which time the assessed amount has compounded.

The cost of an opinion before a transaction is almost always lower than the cost of remediating it afterwards, both in money and in time spent explaining.

Common challenges

  • Applying habit rather than rules. Treating a new transaction the way a previous, materially different one was treated is a common source of error.
  • Foreign contractor tax missed. Payments to overseas suppliers made without withholding, discovered at inspection together with accumulated interest.
  • Transfer pricing documentation not prepared. Dealings with the parent and group companies can trigger declaration and documentation obligations. Missing them exposes the company to a determined price.
  • Profit repatriated at the wrong time. Remittance is subject to conditions and timing. Getting the sequence wrong means the bank declines the transfer or the position is challenged later.
  • Advice without a documented basis. An informal answer with no legal reference is of no help when the company has to explain itself to the tax authority.

How TrustlineAX helps

  • Transfer pricing position assessed. Identification of related parties, declaration and documentation obligations, and an assessment of the risk in your current intercompany pricing.
  • Foreign contractor tax determined. Which payments fall within scope, the calculation method and rate, the withholding obligation and the filing mechanics.
  • Profit and capital repatriation planned. Conditions reviewed, the permissible timing established, documentation prepared and the transfer routed correctly.
  • Tax incentives verified. Whether the company qualifies, what must be maintained to keep the benefit, and the exposure if conditions are not met.
  • Options rather than a single answer. For each situation we set out the workable positions with their respective risk, so the decision remains a commercial one made with full information.
  • Written opinions when you need them. Formal written advice where you need something for the file or for your parent company.

Who we work with

  • FDI subsidiaries with royalties, service fees or management charges paid to the parent company.
  • Companies with expatriate staff whose personal income tax position needs to be right from the start.
  • Finance teams preparing for a tax inspection or closing an inspection already under way.
  • Investors planning to repatriate profit or restructure who need a documented basis before acting.

How we work

  1. Question intake. We establish the substance of the transaction, the parties and what you are trying to achieve.
  2. Document review. Contracts and records examined so the advice reflects the actual arrangement.
  3. Analysis. Applicable rules identified, together with how the tax authority typically approaches this transaction type.
  4. Opinion delivered. Options set out with risk and legal basis for each.
  5. Implementation support. Assistance with documentation, filings or dealings with the authorities if required.

Options, not just one answer

Where the law leaves room for judgement, we set out the realistic options side by side so the decision stays a commercial one made with full information.

Frequently asked questions

How are your fees structured?

Ongoing tax compliance is billed as a fixed monthly fee based on your filing cycle and volume. For a clearly bounded advisory question we quote a fixed fee for the matter; where substantial document review is needed, we quote after a preliminary assessment.

Will you advise on a single transaction?

Yes. You do not need an ongoing engagement to obtain a technical opinion on one situation.

Does a written opinion protect us with the tax authority?

An adviser’s opinion does not substitute for official guidance from the tax authority. That said, a file containing documented analysis and legal reasoning puts you in a substantially stronger position than having nothing on record.

Can we obtain a ruling from the tax authority?

Yes. For unclear or high value matters a company can submit a written query to the tax authority. We draft the submission and follow it through to response.
