I'm perplexed, and hope someone can help me. A CPA does my mom's taxes, and a different CPA does our taxes. Both of them specialize in taxes. I was curious and checked their taxes-owing figures against the IRS website tax tables. In my mom's case, her tax return shows taxes owed of $17,519. When I check her taxable income against the tax tables, the table shows taxes of $19, 242. Nearly 10 percent more. She is a single taxpayer.
In our case, our tax return shows taxes owed of $10,639. The IRS tables show taxes of $12,304 for our taxable income. 15% more. We are married, filing jointly.
What am I missing here?
None of us are subject to AMT.
