Area II: Entity Tax Compliance
This area covers nonroutine compliance for C corporations, S corporations, partnerships, trusts and exempt organizations. The recurring task is to follow noncash property into and out of an entity and track the owner's basis. International items are limited to general sourcing and structure concepts; foreign law and treaties beyond the basic permanent establishment idea are not tested.
C corporations: losses, transfers, distributions and consolidation
Net operating losses from recent years carry forward only, subject to an 80% limit. Corporate capital losses offset only capital gains. A change in ownership caps the use of old losses. Section 351 governs transfers of property to a controlled corporation, and distributions of appreciated property trigger gain at the corporate level. Affiliated groups may file one consolidated return, which defers gains on sales between members.
International concepts
Income is sourced by type: interest by the payor's residence, services where performed, royalties where the property is used, and purchased inventory where the sale occurs. A foreign corporation pays a 30% gross-basis tax on passive U.S.-source income, collected by withholding. Its effectively connected income is taxed on a net basis, and a U.S. branch also faces the branch profits tax. A controlled foreign corporation is defined by the stock held by its 10% U.S. shareholders.
S corporations and partnerships
Both pass income through to their owners, but basis works differently. An S shareholder's basis comes from stock and direct loans to the corporation. A partner's basis also includes a share of the partnership's debts. Distributions of property are taxable events for an S corporation but generally not for a partnership. Ownership changes bring per-day allocations, closing of the tax year for a departing partner, and optional or mandatory basis adjustments.
Trusts and exempt organizations
A trust is a simple trust in a year it must distribute all income, makes no charitable gifts and distributes no corpus; otherwise it is complex. Distributable net income caps the distribution deduction and carries the character of trust income out to beneficiaries. A revocable trust is a grantor trust. Exempt organizations keep their status by staying within §501(c)(3) and filing annual returns, and they pay tax on unrelated business income.
