15.1 Reporting Items from Pass-Through Entities

Key Takeaways

  • A default single-member LLC is disregarded: the owner reports the activity on Schedule C, E, or F and does not receive a K-1.
  • Ordinary business income (loss) is the pass-through residual reported on Schedule E, Part II; it is not the sum of every K-1 box.
  • Charitable contributions, §179 expense, capital gains and losses, tax-exempt interest, and partnership guaranteed payments are separately stated so owner-level character and limits apply.
  • QBI figures on the K-1 are informational inputs to the individual's §199A computation, not a second income line.
  • Basis, at-risk, and passive-activity rules may limit a reported loss; this section classifies the items, and chapter 16 measures how much loss is currently allowed.

15.1 Reporting Items from Pass-Through Entities

REG Blueprint Area IV, Group B asks you to use information provided from disregarded and pass-through entities in which an individual has an ownership interest to report the owner's share of ordinary business income (loss) and separately stated items on the individual's Form 1040. This section is classification and reporting. Whether a reported loss is currently deductible is a later limitation problem — basis, at-risk, and passive-activity rules live in 16.1 and the entity-basis chapters. Do not net separately stated items into ordinary income just because they appear on the same Schedule K-1.

Disregarded entities do not issue a K-1

A single-member LLC owned by an individual is, by default, a disregarded entity under the check-the-box regulations. There is no partnership, no Form 1065, and no Schedule K-1. The owner reports the activity as if the LLC did not exist:

Activity of the disregarded LLCWhere the individual reports it
Trade or businessSchedule C (Form 1040)
Rental real estateSchedule E
FarmingSchedule F

If that LLC elects to be classified as an association taxable as a corporation, the reporting changes: a C corporation files Form 1120 and issues no K-1; an S corporation files Form 1120-S and issues a Shareholder's Schedule K-1. Entity classification is 20.3. The favorite REG trap is treating a default single-member LLC as a partnership because the legal name includes "LLC."

A multi-member LLC is a partnership by default and issues Form 1065 Schedules K-1.

Pass-through K-1s: three common forms

EntityInformation returnOwner's K-1
Partnership (including multi-member LLC)Form 1065Partner's Schedule K-1
S corporationForm 1120-SShareholder's Schedule K-1
Estate or trustForm 1041Beneficiary's Schedule K-1

Each K-1 reports the owner's allocable share. Character is determined at the entity and preserved at the owner. Ordinary business income does not become capital gain on the 1040 merely because the owner is an individual, and tax-exempt interest does not become taxable merely because it flowed through a partnership.

Ordinary business income versus separately stated items

Ordinary business income (loss) is the entity's net income from its trade or business after deducting items that do not have a special character at the owner level, including (for partnerships) guaranteed payments. It is the figure that typically lands on Schedule E, Part II. It is not the sum of every box on the K-1.

Separately stated items are items whose tax treatment depends on the owner's other facts — AGI, filing status, whether the owner itemizes, the owner's §179 limit, the owner's capital-loss netting. If those items were buried in ordinary income, the owner's limitations would be computed at the wrong level. Entity-level ordinary and separately stated mechanics are developed for S corporations in 19.2 and for partnerships in 20.1. This chapter uses those K-1s as inputs to the 1040.

REG's working catalog:

K-1 itemWhy it is separately statedWhere it generally goes on the individual's return
Ordinary business income (loss)The trade-or-business residualSchedule E, Part II
Guaranteed payments (partnerships)Ordinary to the partner; already deducted in computing partnership ordinary income; often self-employment incomeOrdinary income to the partner (typically Schedule E, with SE tax as applicable)
§179 expenseThe dollar and taxable-income limits apply at the ownerOwner's Form 4562; not netted into Schedule E ordinary
Charitable contributionsAGI percentage limits and the itemize-or-not choice apply at the ownerSchedule A, if the owner itemizes (15.3)
Capital gains and lossesNetting and the $3,000 ordinary-offset rule apply at the ownerSchedule D / Form 8949
Tax-exempt interestExcluded from taxable income; may still affect MAGI computationsReported as tax-exempt interest, not as taxable Schedule E income
Interest, dividends, §1231 gains, credits, foreign taxesCharacter and limitations are owner-levelThe matching 1040 schedule or form
QBI informationInformational; not itself a 1040 income lineFeeds the §199A computation in 15.4

Guaranteed payments (IRC §707(c)) are a partnership-only concept. The partnership deducts them in arriving at ordinary business income, then reports them separately to the partner who received them. An S corporation pays wages (Form W-2) to a shareholder-employee; it does not make guaranteed payments. Do not recharacterize W-2 wages as K-1 ordinary income, and do not treat a guaranteed payment as a separately stated capital item.

QBI information on the K-1

Section 199A is computed on the individual's return, not on the entity return. The K-1 therefore includes a QBI statement: qualified business income (or loss) from the trade or business, W-2 wages, unadjusted basis immediately after acquisition (UBIA) of qualified property, whether the activity is a specified service trade or business (SSTB), and any qualified REIT dividends or publicly traded partnership income. Those amounts are inputs. They are not additional Schedule E income. A K-1 that shows ordinary income of $40,000 and QBI of $40,000 is not reporting $80,000 of income.

Losses: report the character, then apply the limits

A K-1 ordinary loss is still classified as an ordinary pass-through loss. Current deductibility is then tested, in order, against:

  1. The owner's basis in the partnership interest or S corporation stock (and S corporation debt basis) — 20.2 and 19.3
  2. The at-risk amount under §465
  3. The passive activity rules under §469
  4. The excess business loss limitation

REG will give you a K-1 and ask where the items go. A later stem will ask how much loss survives. This section answers the first question. Do not refuse to classify a loss because a limitation might apply later, and do not assume a K-1 loss is automatically deductible in full.

Worked scenario: four boxes, four destinations

Facts. Morgan, a calendar-year individual, is a 40 percent partner in Harbor Associates, a general partnership that operates a domestic retail trade. Harbor issues Morgan a Schedule K-1 showing:

  • Ordinary business income: $40,000
  • Section 179 expense: $8,000
  • Charitable contributions (cash to public charities): $2,000
  • Tax-exempt interest: $1,000

Morgan materially participates, has ample partnership basis and at-risk amount, and is not in a passive activity. Harbor also provides a QBI statement showing QBI of $40,000 (the §179 is a QBI deduction at the owner if Morgan actually claims it).

Analysis.

  1. Ordinary $40,000. Report on Schedule E, Part II. It is included in gross income. It is not reduced on Schedule E by the §179, the charitable contribution, or the tax-exempt interest.
  2. §179 $8,000. Separately stated. Morgan computes the §179 deduction on Form 4562 using Morgan's own dollar and taxable-income limits, including other §179 from other sources. Cost-recovery mechanics are 13.2. If the owner's limit is $8,000 or more and the taxable-income limit is met, Morgan deducts $8,000 — but not as a reduction of the $40,000 Schedule E ordinary figure. If the owner's limit is smaller, the unused §179 carries forward at the owner.
  3. Charitable $2,000. Separately stated. It is not a partnership ordinary deduction on Morgan's Schedule E. If Morgan itemizes, it is a Schedule A charitable contribution subject to Morgan's AGI percentage limits. If Morgan takes the standard deduction, the $2,000 does not produce a current charitable deduction.
  4. Tax-exempt interest $1,000. Reported as tax-exempt interest on the 1040. It is not included in taxable income and is not QBI. It can still affect MAGI-sensitive computations (for example, the taxability of Social Security benefits).
  5. QBI statement. The $40,000 of QBI (adjusted for any §179 Morgan actually claims against that business) is an input to 15.4. It is not a fifth income line.

Wrong answers REG writes. Netting everything to $40,000 − $8,000 − $2,000 + $1,000 = $31,000 of Schedule E income. Treating the tax-exempt interest as taxable dividend income. Putting the charitable contribution on Schedule C. Issuing a K-1 from a default single-member LLC.
