SAT 2026 holiday period: key dates and impact on tax procedures
On 9 July 2026, the First Resolution Amending the 2026 General Tax Rules (Resolución Miscelánea Fiscal para 2026) was published in the Official Gazette of the Federation (Diario Oficial de la Federación). Through this resolution, the Tax Administration Service (SAT) announced its first general holiday period, which will run from Monday 20 July to Friday 31 July 2026. During this period, these days will be regarded as non-business days for the purposes of actions carried out by the tax authorities.
What does this mean for taxpayers?
During this period, the calculation of time limits relating to various procedures and formalities currently being processed before the SAT will be suspended. Accordingly, such time limits will resume running from Monday 3 August 2026.
It is important to note that this suspension only affects the calculation of time limits applicable to the tax authorities. Consequently, taxpayers’ tax obligations falling due during this period are neither suspended nor extended.
