Non-excluded recapture

How the math works

Appreciation = sale − investment. Excluded portion = appreciation − recapture. Tax savings = excluded × LTCG rate.

The 10-year QOZ step-up is the most tax-efficient exit path available for US real estate investors. On $2M invested with 2.4x appreciation, the step-up saves $650k+ at combined federal rates — often more than the QOF's operating return across the full hold. Don't exit before year 10 without running this math first.

How this calculator works

What this page estimates

This Opportunity Zone Basis Step Up Calculator is built to give a quick, browser-based estimate for opportunity zone basis step up. 10-year QOZ hold triggers basis step-up. This calculator sizes benefit. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the opportunity zone basis step up result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this opportunity zone basis step up estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

Step-up mechanics?

Hold QOF investment 10+ years, elect to step up basis to FMV at sale. Entire appreciation excluded from tax. Unique to QOZ — no other tax structure provides 10-year full exclusion. Effectively turns 2-3x return into tax-free.

Depreciation recapture?

Still recaptured in some cases. IRS guidance evolved — check current rules. Generally: depreciation taken during holding period not subject to recapture at sale (post-2019 final regulations). But applied only to QOF itself, not underlying QOZB property.

Sunset?

Current QOZ program authorized through 2028. Potential extension/modification likely. Keep track of legislative changes — program has been tweaked multiple times since 2017 TCJA.
