FK Command Center is a software-as-a-service application that models the cash flow, tax, and operational economics of a Turo car-sharing host business. It includes calculators for depreciation strategy (Bonus, Section 179, MACRS), Self-Employment tax, S-Corporation election analysis, quarterly estimated tax pacing, fleet acquisition decision support, profit-and-loss reporting, mileage and maintenance tracking, and other operational tools.
The calculators apply IRS rules in effect at the time the rule was added to the product. Tax law changes — sometimes mid-year, sometimes retroactively. Always confirm the current-year figures against the most recent IRS publications or with your CPA.
Calculators are built from a combination of published IRS Revenue Procedures, the Internal Revenue Code (IRC), the One Big Beautiful Budget Act (OBBBA, 2025), CPA-vetted operational practice, and the founder's direct experience operating a Turo fleet of 22 vehicles. Where the product applies an approximation (for example, the federal bracket integration uses MFJ / Single / HoH tables and does not model the §199A SSTB phaseout or the 0.9% Additional Medicare surtax), the calculator's in-app help text or footnote calls that out explicitly.
If a number on your screen disagrees with what your CPA tells you, your CPA wins. Email [email protected] with the specific discrepancy and we will either fix the calculator or document the assumption that produced the difference.
FK Command Center supports tax years 2024, 2025, and 2026. Calculators read the active tax year from the in-app selector. The Social Security wage base, standard deduction, §179 limits, Bonus depreciation rates, and federal income tax brackets are all year-keyed and update automatically. State tax brackets are integrated for California, New York, New Jersey, Oregon, Hawaii, and Minnesota; other states fall back to a flat top-rate approximation that may understate savings by zero to five percent for filers below the top bracket.
The CPA Handoff package generator produces a read-only, time-limited URL containing your tax-year summary, depreciation schedule, mileage log, and itemized expense list. The packet is intended as a starting point for your CPA — it is not a substitute for source documents (1099-K, settlement statements, repair invoices, insurance receipts) that your CPA will request directly from you.
The Ask FK natural-language assistant sends a snapshot of your business data to a third-party large-language-model provider (Anthropic Claude or OpenAI, depending on configuration) with each question. Do not include any information in your Ask FK questions that you would not be comfortable sending to a third party. Your data is not used to train the underlying model under the provider's enterprise terms.
