Pass-Through Entity

The most common pass-through structures are partnerships (including limited partnerships and LLCs taxed as partnerships), S corporations, and sole proprietorships. The term "pass-through" simply means the entity is transparent for income-tax purposes: income is taxed once, at the owner level, rather than twice as it would be inside a C corporation. Owners report their share of results on their personal returns, often via a Schedule K-1.

For wealthy families, pass-through structures appear almost everywhere: operating businesses, real estate holdings, family limited partnerships used in estate planning, and most private market funds. Understanding the pass-through concept matters because the character of income, whether it is ordinary income, long-term capital gain, or something else, is preserved as it flows through to the owner, affecting the rate at which it is taxed.

A common confusion is treating pass-through income as equivalent to cash received. A family partner in a real estate limited partnership might be allocated taxable income in a year when the partnership distributed nothing, meaning a tax bill without a corresponding deposit. This mismatch between taxable income and cash distributions is one reason families with significant pass-through exposure work closely with a CPA on estimated tax planning throughout the year.
