Understand why you got a K-1
Partnerships and S-corps do not pay income tax on their own. They pass the income to the owners. Your K-1 shows your share. You report this share on your own return. You pay tax on it yourself. This is true even if the business paid you no money.

Wait for the final K-1 before filing
K-1s often come in March or later. That is after the deadline for your own return. Do not file with a guess unless you must. A corrected return costs more than an extension. File Form 4868 to extend your time to October 15 if the K-1 is late.

Boxes 2–14: the pass-through items
Box 2 is rental real estate income. Box 4 is interest. Box 5 is dividends. Capital gains go in 9a/9b and then to Schedule D. Section 179 depreciation goes in 12 and then to Form 4562 for that part. Self-employment earnings go in 14 and then to Schedule SE. Credits go in box 15 on the Form 1065 K-1 and then to credit forms. Credits go in box 13 on the Form 1120-S K-1 in that case. Each box goes to its own form. Software does this on its own if you enter the K-1 in the right section.

Distributions (Box 19) are usually not taxed again
Cash the business sent you is a return of your own money in most cases. It is not extra income. The tax is on the Box 1 amount. Keep track of your outside basis. If you get back more than your basis, the extra is a capital gain.

Be Careful
Don't make these mistakes
Filing before the final K-1 arrives. K-1s often come in March or later. Do not file with a guess unless you must, because a corrected return costs more than an extension. File Form 4868 to extend your time to October 15 if the K-1 is late.
Thinking distributions are the taxable amount. The tax is on the Box 1 ordinary business income amount. Cash the business sent you, in Box 19, is a return of your own money in most cases and is usually not taxed again.
Assuming no tax because no money arrived. You pay tax on your share of the business income even if the business paid you no money. This catches new partners by surprise each year.
Entering boxes in the wrong place. Each box goes to its own form: Box 1 to Schedule E Part II, capital gains to Schedule D, and self-employment earnings in Box 14 to Schedule SE. Enter the K-1 in the right section of your software so it flows correctly.
Losing track of carryovers. Losses you cannot claim now can move to later years, and the same is true for losses from passive work and for credits. Write them down now, or a tax preparer will charge you to rebuild this history.
