A summary of the top weekly tax developments in the Americas

     This week's tax news from the Americas

• Argentina replaces procedure for applying tax-treaty benefits to payments to foreign beneficiaries
  In General Resolution 5,855 (the Resolution, published 3 June 2026), Argentina introduced a new procedure for applying special tax treatment under its tax treaties to Argentine-source income paid to nonresidents. The rules apply even if the relevant treaty fully exempts the income from withholding. Foreign beneficiaries must evidence tax residence exclusively through a valid tax-residence certificate and obtain an affidavit from the foreign beneficiary (following the template included in the Resolution).

• Uruguay presents bill to Parliament to approve tax treaty with Qatar
  On 29 May 2026, the Uruguayan Executive Branch submitted a bill to Parliament to approve a tax treaty between Uruguay and Qatar. Both countries had signed the treaty on 7 December 2025. The treaty aims to eliminate double taxation, promote and protect economic relations, and enhance international tax cooperation by exchanging information between the two countries.

• OECD releases Public Consultation Document on 'Revisions to Chapter VII of the OECD Transfer Pricing Guidelines'
  The Organisation for Economic Co-operation and Development (OECD) released a Public Consultation Document (the Consultation Document) on "Revisions to Chapter VII of the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations". The Consultation Document addresses the accurate delineation of intra-group services and the determination of the arm's-length charge and related conditions. It also addresses documentation considerations intended to supplement the guidance in Chapter V. The Consultation Document introduces new examples to aid in the practical application. Stakeholders are invited to comment on all aspects of the draft, including the opportunity to respond to several specific questions on matters for which it is noted that input will be particularly valuable to the OECD Working Party in preparing subsequent iterations of the draft. Comments are requested by 22 July 2026, and the OECD intends to hold a public consultation in November 2026.
