Frequently Asked Questions
Pro Tips
Maximizing your 401k or IRA contributions reduces your taxable income dollar-for-dollar. In the 22% bracket, a $6,500 IRA contribution saves $1,430 in taxes immediately.
Your marginal tax rate is NOT what you pay on all your income. It only applies to income above the threshold. Someone in the 22% bracket pays far less on average.
Self-employed? Track every business expense year-round — home office, internet, phone, mileage. Most people miss deductions and overpay by hundreds or thousands annually.
Bunching charitable deductions into alternate years can let you itemize every other year rather than taking the standard deduction every year, maximizing total tax savings.
