Frequently Asked Questions
Why is my take-home pay different from what the calculator shows?

Yes, our calculator automatically applies the standard deduction based on your filing status ($14,600 for single filers, $29,200 for married joint filers in 2024).
Can I use this for self-employment income?
While the calculator provides a good estimate, self-employed individuals should also account for the additional 7.65% self-employment tax (the employer portion of FICA).
