On April 18, 2022, US citizens were rushing to submit their federal and state tax returns, leading to a significant spike in traffic to official tax-related websites. The traffic increased by more than 470% on Tax Day compared to the average level on March 31. This surge was even higher than the previous highest growth day in April. Additionally, there were peaks of traffic for state official tax sites and various tax services throughout the month, with a significant increase observed right before Tax Day. Overall, these trends indicate that many people tend to leave their tax returns until the last possible moment.
