Basis (partnership or S corporation)

Your investment in a pass-through entity, adjusted each year for income, losses, contributions, and distributions. It limits the losses you can deduct and determines whether distributions are taxable.

What is Basis?

Your investment in a pass-through entity, adjusted each year for income, losses, contributions, and distributions. It limits the losses you can deduct and determines whether distributions are taxable.

Why it matters on your return

Distributions above basis are taxable gain, and losses beyond basis are suspended. The IRS now requires basis reporting on Form 7203 for S corporation shareholders, so a running basis schedule is not optional.

Example

You invest $20,000 in an S corporation. Year one it earns $30,000 (basis $50,000) and distributes $60,000. The extra $10,000 is a taxable capital gain, not a tax-free return of capital.

Who tracks my basis?

You do, or your preparer does. The K-1 does not show it. We maintain a basis schedule for every pass-through client.
