What this tool covers

Calculation scope

  • Keeps ordinary income and long-term capital gains separate.
  • Collects the self-employment-tax amount explicitly because partner status matters.
  • Does not assume cash distributions equal taxable K-1 income.

Frequently asked questions

Do I owe tax if the partnership did not distribute cash?

Possibly. Partners generally include their distributive shares of partnership items whether or not the partnership distributed cash.

Is all Box 1 income subject to self-employment tax?

No universal answer applies. General-partner, limited-partner, service, and guaranteed-payment rules can differ. Enter only the amount the K-1 instructions and your facts treat as self-employment income.

Why is this not a return-preparation calculator?

Basis, at-risk limits, passive activity rules, QBI, credits, NIIT, state sourcing, entity type, and special box codes can materially change the return.
