You must carefully follow IRS rules if you want to divide profits and losses in a way that’s disproportionate to the owners’ interests in the business.
If a business splits up profits and losses in a way that is not proportionate to the owners’ percentage interests in the business, it’s called a “special allocation.” The IRS pays careful attention to special allocations to be sure business owners aren’t playing hide and seek with potential tax dollars – say, by allocating all business losses to the owner in the highest income tax bracket.
If the IRS doesn’t accept a special allocation that you make, it will tax you and your co-owners as if your distributive shares are in proportion to your ownership interests, regardless of what your partnership or operating agreement says.
To be certain that a special allocation is legitimate, the IRS checks to see if it has what it calls “substantial economic effect.” This jargon means that a special allocation must be based on real economic factors of the owners’ circumstances – not used to simply shift income around to reduce an owner’s income taxes.
Unfortunately, the IRS regulations covering substantial economic effect go on for about 80 pages (Sections 1.704.1 through 1.704.3 of the Income Tax Regulations), so if you want to set up a special allocation, you’ll need expert help to make sure that your allocation will pass muster with the IRS. A good accountant or tax lawyer – one who provides advice on this area of tax law as a regular part of her practice – can draft special language for your partnership or operating agreement to ensure that the IRS will accept your special allocation.
