Financial Calculators

Quick, interactive estimates to help you plan. All figures use 2026 tax parameters. These tools are for informational purposes. Reach out and we'll help you apply them to your specific situation.

Estimates only. These calculators use 2026 federal figures and simplifying assumptions. They do not account for state taxes, tax credits, the QBI deduction, AMT, or your full financial picture, and they are not tax advice. Please before making decisions.

Tax Refund Estimator

A quick federal refund (or balance-due) estimate for W-2 employees filing a basic Form 1040.

Defaults to the 2026 standard deduction for your filing status. Edit if you itemize.
Adjusted gross income $0
Taxable income $0
Income tax before credits $0
Total federal tax $0
Federal tax withheld $0
Estimated refund $0

A rough estimate for a straightforward W-2 return using the 2026 standard deduction and brackets. It applies the Child Tax Credit (with income phase-out) but not the EITC, education, or other credits, refundable-credit nuances, or state tax. Your actual result will vary. We're happy to run the real numbers.

Self-Employment Tax

Estimate the Social Security and Medicare tax on your net self-employment earnings (Schedule C), plus the deductible half.

Net earnings subject to SE tax $0
Social Security portion (12.4%) $0
Medicare portion (2.9%) $0
Total self-employment tax $0
Deductible half (income adjustment) $0

Assumes net earnings = profit × 92.35%, Social Security capped at the 2026 wage base, and no other W-2 wages. The deductible half excludes the Additional Medicare Tax.

Estimated Quarterly Tax

Project your annual federal tax and break it into four estimated payments.

Defaults to the 2026 standard deduction for your filing status. Edit if you itemize.
Estimated taxable income $0
Income tax $0
Self-employment tax $0
Total estimated federal tax $0
Less withholding / payments $0
Suggested quarterly payment $0

Simplified: excludes tax credits, the QBI deduction, NIIT, AMT, and state tax. 2026 estimated payments are generally due Apr 15, Jun 15, Sep 15, and Jan 15 of the following year. We can confirm your safe-harbor amount.

S-Corp Election Analysis

For a profitable sole proprietor or single-member LLC: estimate a reasonable salary, the self-employment-tax savings from electing S-corp status, and whether it's worth it after the added costs.

Affects the QBI deduction at higher incomes.
Suggested reasonable salary $0
Taken as distributions $0
SE tax now (sole proprietor) $0
Payroll tax as an S-corp $0
Payroll-tax savings $0
Est. S-corp admin cost $0
Estimated net benefit $0

Reasonable salary here is a rough starting point (about half of profit, with a floor). Real reasonable compensation depends on your role, industry, and market wage data. Savings compare Social Security + Medicare only; admin cost is an estimate for payroll, the Form 1120-S return, and state fees. Talk to us before electing.

Retirement Contribution

Estimate the maximum you can contribute to a self-employed retirement plan for 2026 based on your net self-employment income.

Catch-up contributions apply at 50+, with a larger amount at ages 60–63.
Net earnings for plan purposes $0
Employee / salary deferral $0
Employer contribution $0
Estimated maximum contribution $0

Uses net earnings = profit × 92.35% minus half of self-employment tax. SEP and the Solo 401(k) employer portion use the 20% effective self-employed rate, capped at the 2026 defined-contribution limit. SIMPLE assumes a 3% employer match.
