Last Updated: April 2026

We welcome feedback, bug reports, and questions regarding our tax calculation methodology. As an independent research project, we are constantly looking to improve the accuracy and educational value of our tools.

Get in Touch

If you have questions about the tool or noticed a discrepancy in the state tax data, please reach out to us at our current working email:

llcvsscorpcalculator@gmail.com

For calculation feedback, please include the page URL, selected state, filing status, annual profit, salary mode, and the result that looked incorrect. That detail helps us reproduce the scenario without asking for sensitive records.

Important Professional Notice:

Messages sent to this project do not create a CPA-client, attorney-client, or any other professional relationship. We cannot provide personalized tax, legal, or financial advice. If you need assistance with your specific tax situation, please consult a qualified professional in your jurisdiction.

Frequently Asked Questions

Before reaching out, you may find the answer to your question in our core resource guides:

If your question is about a personal tax filing, payroll setup, Form 2553 timing, or whether your salary is defensible, use the site as preparation for a licensed professional rather than as final advice.
