Frequently Asked Questions
What is a Schedule K-1?
A Schedule K-1 reports a partner’s or shareholder’s share of income, deductions, credits, and other items from a pass-through entity. Partnership K-1s come from Form 1065; S corporation K-1s come from Form 1120-S.
Why does basis matter?
You generally cannot deduct losses or receive tax-free distributions beyond your basis. Keep annual stock/debt (S corp) or outside basis (partnership) schedules even if the K-1 looks complete.
When should I expect my K-1?
Pass-through entities often issue K-1s in March or later. Many individuals extend Form 1040 while waiting. Ask the entity for an estimated K-1 if you need to project payments.
Do state K-1s differ?
Yes. States may require separate K-1 equivalents, withholding, or composite returns. Keep federal and state K-1 packages together.
