Form 1040 is the primary document used by individuals to report their annual income, calculate their tax obligation, and outline deductions and credits they are eligible for. This form serves as the foundation for personal income tax returns in the United States, capturing essential information about earnings from various sources, allowable deductions (such as qualified expenses), and tax liabilities. Through Form 1040, taxpayers are able to present a comprehensive view of their financial situation for the year, which ultimately determines whether they owe additional taxes or can expect a refund.

While other forms and documents may serve specific purposes, such as summarizing tax credits or applying for refunds, Form 1040 encompasses a broader scope by integrating income reporting and tax calculations, making it crucial for accurate tax filings for individuals. Additionally, business registration is not a function of Form 1040; it focuses solely on personal income taxation.
