What is a Tax overpayment?

A tax overpayment occurs when a self-employed individual's quarterly estimated payments exceed actual tax liability on Form 1040. This typically results from fluctuating income, conservative projections, or late-year deductions not fully anticipated during the year. The excess appears on line 35a and triggers a choice between requesting an immediate refund or applying the balance to next year's estimated taxes — an election that becomes irrevocable once filed. Reducing taxable income through a Health savings account contribution lowers quarterly obligations and helps prevent future overpayments.
