The calculations I used to use don't work now that all our income is from self employment. I know I begin with gross less expenses for net self employment income. I need to know at what point I plug in things like: dividend/interest income, self employment tax, sep and traditional ira contributions, self employed health insurance premiums, std. deduction, exemptions (or has that been eliminated?)..... Meaning, how do I get the taxable income figure that I then take to the tax tables to figure estimated tax due? Do I use the rate schedule on pg. 33 in Pub 505 or the tax w/holding tables for wages?
Thanks.
