Tax Deductions, Business vs. Investment Activities, and Loss Limitations

Vocabulary flashcards covering the distinctions between for and from AGI deductions, business vs. investment activities, reporting schedules, and flow-through loss limitation rules.

For AGI deductions

Deductions available to all eligible taxpayers, not just those who itemize deductions, which reduce AGI and thereby reduce the limitations on other tax benefits that phase out at higher income levels.

Business activities

Profit-motivated endeavors that require a high level of effort or relatively high level of involvement from the taxpayer (also referred to as trade activities).

Investment activities

Profit-motivated endeavors that do not require a relatively high level of involvement or effort from the taxpayer.

Ordinary and necessary

The statutory requirement for business expenses to be deductible, meaning they must be directly related, customary, and appropriate for the business activity.

Schedule C (Form 1040)

The tax form schedule where individual business expenses and revenues are reported, rather than being entered directly on Form 1040.

Rental and royalty activities

Endeavors most commonly classified as investment activities whose associated expenses are always deductible for AGI and reported on Schedule E of Form 1040.

Investment interest expense

An investment-related expense that is deducted from AGI, unlike self-employed business expenses which are deducted for AGI.

Flow-through entities

Entities such as partnerships, LLCs, and S corporations whose income, expenses, and losses flow through to the owners' tax returns, typically deductible for AGI.

Schedule E (Form 1040)

The tax schedule used to report income and deductions resulting from rental properties, royalties, and flow-through entities.

Operating loss hurdles

The three statutory hurdles a taxpayer must clear to deduct an operating loss from a flow-through entity: tax basis, at-risk limits, and passive loss limits (net investment limits is not a hurdle).

At-risk amount rules

Tax rules designed to limit an investor's ability to deduct artificial ordinary losses generated with certain types of debt; if different from tax basis, the at-risk amount will be lower.

Capital loss deduction limit

A maximum net allowance of $3000$ per year that individuals can deduct against ordinary income for investment asset losses, with any excess loss carried forward.

Passive activity loss rules

Rules that restrict the deduction of losses from business activities even when a taxpayer has sufficient tax basis and at-risk basis, applied if the taxpayer does not materially participate.

Material participation

A standard of active taxpayer involvement in business operations required to deduct business losses; does not require full-time involvement and can be met via prior years of service or combined hours across multiple activities.

Personal use asset losses

Losses generated from the sale or disposal of assets held for personal use, which are strictly nondeductible for AGI.
