The National Tax Service (SIN) has extended the Corporate Profits Tax deadline to 15 May 2026 for Bolivia's interdepartmental transport sector following technical disruptions to the SIAT Online system that prevented operators from filing their returns using the required Form 501.
Bolivia’s National Tax Service (SIN) has announced an exceptional extension for tax compliance deadlines affecting the interdepartmental transport industry on 13 May 2026.
The new deadline of 15 May 2026 provides additional time for sworn statements and Corporate Profits Tax payments for the 2025 fiscal year.
The extension comes in response to temporary service disruptions in the SIAT Online platform. Board Resolution 102600000015, issued on 8 May 2026, addresses problems that prevented transport operators from accessing Form 501, which is essential for meeting their tax requirements. System improvement work caused the interruptions that made it impossible for many taxpayers to complete their obligations on time.
The extension applies specifically to individual transport operators working in the interdepartmental passenger and freight sectors. This includes both unionised and independent drivers who own up to two vehicles that are at least six years old, as outlined in Supreme Decree 28988. Additionally, individuals whose tax amounts are calculated based on their vehicles’ load and towing capacity under Supreme Decree 29745 also qualify for the extended deadline.
The tax authority emphasised that this decision aims to support taxpayers affected by technical difficulties beyond their control. The extension ensures that transport operators can fulfil their tax obligations without facing penalties or additional charges due to system unavailability during the original compliance period.
