The required annual payment is generally equal to the lesser of (1) 90 percent of the tax shown on the individual’s return for that year (or, if no return is filed, 90 percent of his or her tax for such year), or (2) if the individual filed a return for the immediately preceding taxable year, 100 percent of the tax shown on that return.
