Get your taxes done using TurboTax

@taxfiler101 as @VolvoGirl explained adding $2700 to income can change a lot of things on your tax return. it not the self-employment tax that's federal only and at most would add $400. additional federal income taxes at the top bracket of 37% (for taxable income well over $1/2 million) would add about $900.  Thus, it would seem you're losing some deductions or tax credits. We have no access to your return. You have to compare your returns before and after line by line to see what changes. Then if you have questions about why a specific line changed post back in this thread.
