Tax Day is an annual event in the United States on April 15th. It is the deadline for individuals and businesses to file their income tax returns with the Internal Revenue Service (IRS). This day can be stressful for some people, who may owe money to the government or have difficulty completing their tax forms. However, others may look forward to Tax Day as they may receive a refund from the government. Regardless of how one feels about Tax Day, it is an important event that helps fund many of the government services people rely on daily.
