What We Offer

  • Companies need to ensure they comply with Indonesian tax regulations. We can advise on the tax implications of a contemplated structure or agreement, evaluate risks, and formulate a strategy for an efficient tax structure.

    HSC can provide guidance or perform a review to identify and evaluate risks and provide recommendations to mitigate potential exposure to tax office scrutiny. We can also assist in obtaining a variety of tax facilities offered by the Indonesian government as well as obtaining specific rulings from the Indonesian tax authorities.

    Our advice is based on the relevant regulations as well as our knowledge of how the tax office interprets the rules and operates in practice, and is presented clearly, concisely, and in a way that is easy to understand.

  • To cope with the ongoing business dynamics, we can assist by structuring tax efficient deals, advise on mergers and acquisitions, or devise a tax effective “exit strategy.”

    We can help restructure group companies to enhance their business value whilst maintaining a tax efficient structure for both entry and exit strategy purposes, provide advice on a new organizational structure, suggest tax planning and financing structures for tax efficiency, and create tax policies for managing transfer pricing and other issues.

  • Change the text and add your own content, including any information that is relevant to share. Then customize the font, size and scale to make it your own.

    The Indonesian tax authorities are conducting more frequent and robust tax audits and companies need to be prepared to defend them in a way that is both technically and strategically sound.

    A tax audit is not an easy or straightforward process. We make every effort to anticipate problems and provide advice and assistance during the audit with a view to resolving differences between the company and the tax officials. However, even with a solid technical basis for a position, tax officials may nevertheless issue an assessment. If the company disagrees with a tax audit finding, it can submit an objection to the tax office, which could be followed by an appeal to the Tax Court and possibly judicial review by the Supreme Court.

    We can provide full assistance or advice on an ad hoc basis when dealing with a tax audit and, if an assessment is made, during the objection, appeal and judicial review process. When faced with a tax assessment, it is critical that the dispute is managed competently. We will formulate a strategy for handling any controversy or dispute (at all levels) in the most effective manner and represent your company to help attain the best possible outcome.

    HSC has successfully handled hundreds of tax controversies and disputes, with a very high success rate for cases that proceed to the appeal or judicial review stage, including many preliminary evidence audits (BUPER). Confronted with a BUPER audit, your first reaction may be to settle quickly on unfavorable terms. You may not realize that many of these audits are resolved with a complete exoneration of the taxpayer. If you receive such an audit, don’t panic and don't surrender. We will work with you to assess your situation, determine the best response based on the evidence, and if warranted, prepare a robust defense. Our approach has helped many clients win cases that began with a BUPER audit.

  • Most dispute cases now involve transfer pricing issues. The Indonesian tax authorities are aggressive and closely scrutinize related party transactions. With our strategic alliance with Kroll, we offer global best practice transfer pricing expertise, with awareness of the expectations of the Indonesian tax authorities.

    Our services include transfer pricing documentation in accordance with domestic regulations (local file, master file, country-by-country report) as well as technical and benchmarking analysis for all types of related party transactions.

    We also provide comprehensive and specialized transfer pricing services such as a risk assessment review to identify and quantify the risk of related party transactions, anticipate transfer pricing adjustments in advance of Indonesian tax authority scrutiny, and assist during a transfer pricing audit or dispute.

  • Indonesia has an array of direct and indirect taxes which require the filing of monthly and annual tax returns. These include annual and monthly corporate income and employee income tax returns, as well as monthly returns for withholding tax and VAT. It’s important to not only keep up with your tax compliance but ensure that it is done correctly to minimize future tax office scrutiny. We can help you understand your compliance requirements and assist in the preparation or review of tax calculations and returns. As Indonesia migrates towards a fully automated tax system, we can also help you prepare for compliance to be handled in-house.

  • If your company is involved with importing or exporting goods, HSC’s customs and excise experts can help. We can assist with obtaining exemptions, specific rulings from the Indonesian customs authorities, and other facilities (such as setting up a bonded warehouse).

    We can also help with customs clearance, customs audits and disputes, and provide advice on the customs implications of a contemplated transaction. We can also review current customs and excise procedures to ensure that the company’s practice is efficient and complies with the prevailing regulations.
