Somebody told me to put a $58k gain in an opportunity zone fund, starting from zero

On your third question, plan on the money being gone for the full term. Most of these are ten years plus by design, because the long hold is the whole point of the structure. There's usually no redemption right at all. If there's any chance you need that $58k in four years, the fund answer is off the table before you look at a single deal.

Minimums vary a lot. I've seen $25k on funds that are set up to take a lot of small investors and $250k on ones that aren't. The smaller-minimum funds tend to have more investors to report to, which is part of why the fee load can look different. Ask for the minimum in the first email and save yourself reading a 100-page document for a fund that won't take you.

sable, the timing question is the one to bring to your CPA first, because it decides whether you have a decision at all. October sale means your window is closing in spring and every other question is downstream of that.

Fair warning from someone who moves fast and has paid for it. A deadline is the worst possible reason to pick a fund. There's a whole layer of sponsors who exist because people like you show up in month five with a clock running, and their documents are written for that. Paying tax on $58k is a known cost. A bad ten-year lockup is not.

Your summary of the mechanism is close. An individual with an eligible capital gain reinvests it into a qualified opportunity fund inside the required window, the fund deploys into qualifying property or businesses in designated tracts, and the tax benefits flow back to you as a passive holder. Deferral on the original gain, and for long enough holds, potential elimination of tax on appreciation in the new investment. The specific windows, eligibility of your particular gain and how it's reported are tax questions that belong with your CPA, and they vary by the facts of your sale.

Two structural points for your list of questions.

The One Big Beautiful Bill Act, signed July 4, 2025, made the incentive permanent. It also replaced the fixed deferral deadline with a rolling five-year deferral for investments made after 2026, tightened tract eligibility, added enhanced rural incentives and imposed new reporting requirements on funds. The current tract map runs through the end of 2026 and a new set takes effect January 1, 2027, with the full enhanced benefits available in the new zones. So a gain invested this year and a gain invested in 2027 do not sit under identical rules, which is a specific thing to raise on your CPA call.

On evaluating a manager, the tax structure does not improve the project underneath it. Ask what the sponsor has built and delivered, how many of their prior deals reached stabilization, what construction costs they're carrying today against current bids, and who bears an overrun. Passive OZ outcomes rest on the underlying project economics and the manager's execution, with the tax treatment layered on top.
