Educational only โ not tax, legal, or financial advice. ScanMyTaxes is a software tool, not a tax preparer or advisor, and does not prepare or file returns. Every figure here is an estimate based on the information you enter; results are not guaranteed and depend on your specific situation. The "best" salary shown balances the QBI deduction against payroll tax โ but your salary must still be defensible as reasonable compensation for the work you do, which is the most common thing the IRS challenges; the optimizer will not enforce that floor for you. Payroll tax is estimated as Social Security (up to the $184,500 wage base) plus Medicare and the 0.9% surtax; the deductible employer half is credited back at your rate. Confirm the exact salary with your CPA before changing payroll. Using this tool does not create a client relationship.
