I. HIGH IMPACT TAX UPDATES
1. Tax relief law. Central government. Law No. 1733, (May 27, 2026).
The Law introduces a comprehensive tax relief and regularization framework, with significant implications for historical liabilities, compliance, and tax planning.
Law No. 1733, dated May 27, 2026, has been enacted in Bolivia. The Law establishes an extraordinary tax relief period through debt forgiveness and tax regularization mechanisms applicable to liabilities administered by the National Tax Service and the National Customs Authority.
The Law introduces, among others, the following key measures:
1. Tax debt forgiveness for fiscal periods prior to January 2018, subject to specific conditions and exclusions, as well as forgiveness of tax liabilities and penalties for fiscal year 2020.
2. A tax regularization regime for liabilities corresponding to fiscal periods from January 1, 2018, through December 31, 2025, through cash payments or installment plans of up to thirty-six (36) monthly installments.
3. A reduction of the general statute of limitations for the Tax Administration’s powers from eight (8) years to four (4) years.
4. Amendments to the VAT taxable base rules, including the requirement to separately disclose VAT from the net sale price on invoices.
5. Amendments to Law No. 060 on Lotteries and Games of Chance, including adjustments to the rules applicable to games, raffles, lotteries, and business promotional activities.
These measures are expected to have a significant impact on taxpayers’ compliance obligations, tax controversy strategies, invoicing systems, accounting processes, commercial promotional activities, and overall tax planning.
It should be noted that the original bill contemplated the creation of a Special Integrated Transition System for Entrepreneurs to the General Tax Regime (SIETE-RG, by its Spanish acronym). However, during the legislative process, this proposal was replaced by a broader tax relief regime focused on reducing tax arrears, facilitating the regularization of outstanding liabilities, and addressing tax and customs contingencies.
2. Amendments to financial statements filing, tax information, corporate income tax, and transfer pricing. National Tax Service (SIN). RND No. 102600000014 (April 16, 2026).
The National Tax Service (SIN) has amended the filing regime for financial statements, supplementary tax information, documentation related to Corporate Income Tax (IUE), and transfer pricing obligations, as part of the ongoing digitalization of annual tax compliance.
The key changes are as follows:
1. New threshold for additional documentation. The annual gross revenue threshold triggering the obligation to submit additional documentation increases from Bs 1,200,000 to Bs 1,700,000.
2. Elimination of physical filings. Financial and tax documentation is no longer submitted in physical format and must now be filed digitally through the SIAT platform.
3. Digitalization of the transfer pricing study. The Transfer Pricing Study must now be submitted digitally via SIAT.
4. Form 601 without change of platform. The Informative Sworn Statement of Transactions with Related Parties (Form 601) continues to be filed through the Da Vinci module.
5. Differentiated deadlines for annual compliance. For taxpayers with a fiscal year-end of December 31, 2025, the deadline for filing and paying Corporate Income Tax (IUE) expired on May 4, 2026. The digital submission of financial and tax documentation must be completed by May 29, 2026.
These changes are relevant for fiscal year-end planning, preparation of supporting documentation, consistency between financial statements and tax information, and the documentation of related-party transactions.
3. Amendments to the Invoicing System regarding the use of tax credit from fuel purchases. National Tax Service. RND No. 102600000012 (April 13, 2026).
The National Tax Service (SIN) regulated operational adjustments to the Invoicing System and the Purchase and Sales Registry to implement the calculation of 100% of the VAT tax credit on purchases of gasoline and diesel, within the framework of Law No. 1718. Going forward, taxpayers must record 100% of the amount paid in both the “Total Purchase Amount” column and the “Base Amount for Tax Credit” column, which affects the determination of VAT credits, purchase reconciliations, accounting records, and internal controls for companies with significant fuel consumption.
II. TAX INITIATIVES TO FOLLOW UP AND CONTROL
