Tax Calculators

Use these educational tools to organize your numbers before a tax planning conversation. The estimates are simplified and should not be treated as tax advice or a final filing result.

Federal Tax Owed / Refund Estimator

Estimate federal income tax using filing status, income, deductions, credits, withholding, and payments.

This is an educational estimate only. It does not calculate a full tax return, penalties, EITC, child tax credit phaseouts, AMT, NIIT, additional Medicare tax, state taxes, local taxes, or every deduction or credit.
This version uses the editable 2026 federal tax CONFIG in the code.

How this estimate is calculated

This tool adds W-2 wages and other taxable income, subtracts either the 2026 standard deduction or your itemized deduction amount, calculates federal income tax progressively by bracket, applies nonrefundable credits up to the tax amount, and compares the result with withholding and payments.

Self-Employed Tax Estimator

Estimate a rough federal tax set-aside for 1099 or self-employed income using net profit, self-employment tax, federal income tax, and payments already made.

This is educational only and does not replace a tax return or professional review. It does not fully calculate QBI, EITC, child tax credit, depreciation, retirement deductions, health insurance deduction, NIIT, additional Medicare tax, state taxes, or penalties.
For this simplified screen, this amount is included in income tax and treated as wage-base-reducing W-2 income for Social Security tax.

How this estimate is calculated

This tool estimates net self-employed profit, applies the 92.35% net earnings factor, calculates Social Security and Medicare self-employment tax, subtracts one-half of SE tax before estimating federal taxable income, applies federal tax brackets, and compares estimated total federal tax with payments.

Cost Seg Quick Estimator

Use this rough screening tool to see whether a cost segregation review may be worth exploring for a rental, commercial, or multifamily property.

This calculator provides a rough educational estimate only. It is not a cost segregation study, tax advice, or a guarantee of tax savings. Actual results depend on your property, land allocation, depreciable basis, placed-in-service date, income, passive activity limits, at-risk rules, entity structure, financing, and current tax law.
If you are not sure, leave this blank and the calculator will estimate building basis as purchase price minus land value plus eligible closing costs.
This answer is collected for review context. The estimate is not reduced for passive activity limitations.

How this screening estimate works

The calculator estimates depreciable basis, applies broad property-type reclassification ranges, applies the selected federal tax bracket, and subtracts the estimated study and professional fees. This is not a formal study. For broader tax planning help, visit Finance With Nyeem services.
