How much of your gain can you keep?
Two inputs. One clear answer. See exactly what you'd owe if you do nothing — and what changes if you invest in an Opportunity Zone.
Pay the tax today, or defer it into a Qualified Rural Opportunity Fund?
Pay Tax Now path includes federal long-term capital gains tax (20%) plus the 3.8% Net Investment Income Tax on appreciation at exit. State tax (13.30%) applied per your selection. QROF path is fully tax-free on appreciation after a 10-year hold under IRC § 1400Z-2.

You have 180 days from your sale date to invest your gain into a Qualified Opportunity Fund. Get notified when your state files OZ 2.0 nominations and when funds go live in your target markets.
Opportunity Zone tax calculator — FAQ
How are Opportunity Zone tax savings calculated?
Opportunity Zone savings come from two mechanisms: deferring tax on the capital gain you reinvest into a Qualified Opportunity Fund, and eliminating tax on the fund's own appreciation if you hold for at least 10 years. This calculator applies the federal long-term capital gains rate (20% plus the 3.8% net investment income tax) plus your state rate, then compares the after-tax outcome of investing in a QOF against simply paying the tax now.
How much tax do you pay on capital gains in an Opportunity Zone?
You defer tax on the original reinvested gain until the earlier of your exit or the deferral deadline, and you pay zero federal tax on the QOF investment's appreciation once it is held 10 years or more. OZ 2.0 also adds a basis step-up — 10% at five years for a standard QOF, 30% for a rural QROF — which permanently reduces the deferred gain that eventually becomes taxable.
Is the Opportunity Zone calculator free?
Yes. The calculator is free, requires no signup, and runs entirely in your browser. It is CPA-reviewed and models OZ 1.0, OZ 2.0 standard QOF, OZ 2.0 rural QROF, a 1031 exchange, and a pay-now scenario side by side over a 10-year horizon.
What is the difference between an Opportunity Zone and a 1031 exchange for taxes?
A 1031 exchange defers tax only on real estate when you roll proceeds into like-kind real estate, and the deferred gain is never forgiven — it carries forward until you sell without exchanging. An Opportunity Zone fund accepts gains from any asset (stock, crypto, business sales, real estate), and after a 10-year hold the appreciation on the fund investment is fully tax-free. This calculator shows both paths against each other.
