Syndications and funds are taxed as partnerships. Income, losses, and distributions flow through to investors based on the allocation rules in the operating agreement. Those rules are not just legal language. The IRS reads them as economic substance.
This is the core of Subchapter K — the section of the tax code that governs partnership taxation. The governing standard is substantial economic effect: allocations of income and loss have to correspond to who actually bears the economic burden of that loss or receives the economic benefit of that income. Translation: who gets the K-1 loss needs to be the person who would actually eat the loss if the deal went sideways.
Most operating agreements are drafted by attorneys who are competent deal lawyers but not partnership tax specialists. The agreement may be enforceable. It may still expose your investors to reallocation by the IRS if the allocations don't hold up under that standard.
