Tideline Partners is one of Southern California’s leading Opportunity Zone developers — combining tax-efficient investment structures with award-winning real estate development.
Opportunity Zones (OZs) are economically distressed communities designated by the federal government under the Tax Cuts and Jobs Act of 2017. By investing unrealized capital gains into a Qualified Opportunity Fund (QOF), investors can access three powerful tax incentives:
1. Capital Gains Deferral
Defer the recognition of existing capital gains until December 31, 2026 by reinvesting them into a QOF within 180 days of the sale.
2. Basis Step-Up
Hold your QOF investment for at least 5 years and receive a 10% step-up in basis on the original deferred gain — reducing your ultimate tax liability.
3. Tax-Free Appreciation
Hold for 10+ years and pay zero federal capital gains tax on all appreciation generated within the QOF — the most powerful benefit of the program.

Reinvest the gain into a Tideline Qualified Opportunity Fund within 180 days of the sale.
Defer Taxes
Your original capital gains taxes are deferred, freeing capital to compound within the fund.

What types of gains qualify for OZ investment?
Most capital gains qualify — including gains from the sale of stocks, bonds, real estate, and business interests. The gain must be reinvested into a QOF within 180 days of the triggering sale.
Do I need to invest the entire sale proceeds?
No — only the capital gain portion needs to be reinvested, not the original cost basis. This makes the OZ program accessible even for investors with large embedded gains.
What is a Qualified Opportunity Fund?
A QOF is an investment vehicle (typically structured as a partnership or corporation) that holds at least 90% of its assets in Qualified Opportunity Zone property. Tideline structures and manages QOFs for its development projects.
How long do I need to hold my investment?
To receive the maximum tax benefit — including zero federal capital gains tax on appreciation — you must hold your QOF investment for at least 10 years. Shorter hold periods still offer meaningful tax deferral benefits.
What happens to my original deferred gain?
Deferred gains must be recognized on December 31, 2026, or upon the earlier sale of your QOF interest. At that point, normal capital gains tax rates apply to the original deferred amount (with any applicable step-up in basis).
Is my investment in real estate or in a fund?
You invest in a Qualified Opportunity Fund managed by Tideline. The fund then deploys capital into specific real estate development projects within designated Opportunity Zones in Southern California.
