Approximately 18.4 million taxpayers in Brazil have not yet filed their 2026 income tax returns [1].
The delay puts a significant portion of the population at risk of penalties as the window for legal submission closes. This volume of outstanding filings suggests a potential bottleneck for the Receita Federal as the deadline nears.
The filing deadline is set for May 29, 2026, at 23:59 Brasília time [1]. According to data from the Federal Revenue Service, 18.4 million people have still not submitted their declarations [1]. This figure represents 57.8% of the taxpayers who were expected to file [2].
In March, the Receita Federal established a target of 44 million total deliveries by the May 29 cutoff [1]. The current gap indicates that a majority of the target population has waited until the final two weeks of the process to comply with the requirement.
Taxpayers who miss the midnight deadline on May 29 face potential fines and complications with their tax status. The Receita Federal manages the process through its digital platforms to streamline the submission of the 2026 returns [1].
Government officials have monitored the progress of these filings since the start of the tax season. The current statistics show that more than half of the required participants remain outstanding less than a month before the official end of the period [2].
“18.4 million people have still not submitted their declarations”
The high percentage of late filers indicates a trend of procrastination among Brazilian taxpayers, which often leads to increased technical strain on government digital infrastructure during the final days of a deadline. With nearly 58% of the target group remaining, the Receita Federal may face a surge in traffic that could impact the efficiency of the filing system.
