Frequently Asked Questions

Which business entity type pays the least tax?
It depends on income level. At lower incomes, sole proprietorship with QBI deduction can be efficient. At higher incomes ($50k+ profit), S-Corps can save on self-employment tax. C-Corps have a flat 21% rate but face double taxation on distributions.
What is the QBI deduction?
The Qualified Business Income (QBI) deduction allows eligible self-employed individuals and small business owners to deduct up to 20% of their qualified business income. It applies to pass-through entities like sole proprietorships, LLCs, and S-Corps.
