18.2 Passive, At-Risk, and Investment Planning
Key Takeaways
- Loss deductibility for an individual owner generally moves through basis, then at-risk, then passive activity limits before a loss reaches the return.
- At-risk rules measure the taxpayer's real economic exposure, while passive activity rules focus on participation and the character of income.
- Passive losses generally offset only passive income, not wages, portfolio income, or active business income unless a supplied exception applies.
- The active-participation rental exception can free up to $25,000 of rental loss, phasing out between $100,000 and $150,000 of modified AGI.
- Suspended passive losses are released when the taxpayer disposes of the entire passive activity in a fully taxable transaction to an unrelated party.
Loss Limits Before Investment Advice
TCP individual planning often begins with a deceptively simple question: can the taxpayer deduct the loss? For a pass-through entity or rental activity, a CPA cannot answer by looking only at the Schedule K-1 or rental statement. The loss must clear multiple filters, applied in a fixed order, before it is allowed on the individual return.
The Loss Limitation Stack
| Order | Filter | Core question | If the answer is no |
|---|---|---|---|
| 1 | Tax basis | Does the owner have enough basis to absorb the loss? | Loss is suspended under basis rules |
| 2 | At-risk amount | Is the owner economically exposed to loss? | Loss is suspended under at-risk rules |
| 3 | Passive activity | Is the activity passive to this taxpayer? | Loss is suspended unless passive income or an exception applies |
| 4 | Excess business loss | Does the aggregate active business loss exceed the supplied annual limit? | Excess is deferred as a net operating loss carryforward |
The order matters: a loss must survive basis to be tested for at-risk, survive at-risk to be tested as passive, and so on. The 2026 TCP blueprint specifically calls for reviewing basis schedules and the source data behind them, so a simulation may supply debt schedules, capital-account detail, partner or shareholder basis schedules, prior suspended carryovers, and current-year activity statements. Reconcile them before deciding how much loss is allowed.
At-Risk Versus Material Participation
The at-risk rules (Section 465) ask whether the taxpayer could actually lose money. Cash contributed, the adjusted basis of property contributed, and recourse debt for which the owner is personally liable increase the at-risk amount. Qualified nonrecourse financing secured by real property also counts, but ordinary nonrecourse debt, stop-loss guarantees, and protected arrangements generally do not create at-risk exposure.
A taxpayer can materially participate and still be limited by at-risk rules. The seven material-participation tests (for example, more than 500 hours in the activity, or more than 100 hours and not less than anyone else) determine passive classification, not economic exposure. TCP questions deliberately separate these concepts, giving enough facts for one limit and asking you to allocate the loss among allowed, at-risk-suspended, and passive-suspended buckets.
A worked sequence: a partner with $40,000 basis but only $30,000 at-risk who is allocated a $50,000 loss may deduct at most $30,000 this year (after passive testing); $10,000 is at-risk-suspended and $10,000 is basis-suspended.
Passive Activity Analysis
The passive activity loss (PAL) rules (Section 469) classify activities by participation. In general, passive losses offset only passive income. They never offset wages, interest, dividends, or active business income merely because the taxpayer wants the deduction.
Rental real estate is per se passive, with two exceptions the exam may supply: the active-participation exception, which allows up to $25,000 of rental loss against nonpassive income and phases out at 50 cents per dollar of modified AGI between $100,000 and $150,000 (fully gone above $150,000); and the real estate professional rules (more than 750 hours and more than half of personal services in real property trades).
A reliable process:
- Group income and losses by activity.
- Determine whether each activity is passive to this taxpayer.
- Net passive income against passive losses.
- Apply any supplied rental real estate exception.
- Track suspended losses by activity and by reason for suspension.
Suspended passive losses are not lost forever. When the taxpayer disposes of the entire interest in a passive activity in a fully taxable transaction to an unrelated party, the activity's suspended losses are released and become fully deductible. Do not release losses for a partial disposition, an installment sale that is incomplete, or a related-party transfer unless the facts support it.
Investment Planning and Taxable-Equivalent Yield
TCP Area I also covers investment planning. The blueprint expects candidates to understand risks of equity securities, corporate bonds, and municipal bonds, and to compute return net of tax when facts are supplied. Compare after-tax return against credit risk, interest-rate risk, market risk, liquidity, diversification, and the client's time horizon.
Municipal bond interest is generally exempt from federal income tax, so compare bonds on a taxable-equivalent yield (TEY) basis using TEY = tax-exempt yield / (1 - marginal tax rate). A 3.5% municipal bond for a client in a 37% bracket has a TEY of 3.5% / (1 - 0.37) = 5.56%, beating a 5.0% taxable corporate bond on an after-tax basis. But a higher TEY does not automatically win: issuer concentration, lower liquidity, call risk, or weaker credit may outweigh the tax benefit. Note also that municipal interest can still affect the AMT (private-activity bonds) and the taxability of Social Security benefits.
The exam answer should connect tax character to the client's stated planning objective, not pick the highest stated yield.
A related TCP skill is computing after-tax return on investment when the facts supply purchase price, sale proceeds, holding period, and tax character. Long-term capital gains and qualified dividends are taxed at preferential rates (0%, 15%, or 20% depending on the supplied income band), while short-term gains and ordinary dividends are taxed at ordinary rates, and high earners may owe the 3.8% net investment income tax on top.
A bond held to maturity returns principal with no gain, so its after-tax return is driven entirely by the coupon's tax character; a growth equity defers tax until sale and may convert appreciation into preferentially taxed long-term gain. When comparing two investments, equalize the holding period and the tax treatment before declaring a winner, and remember that diversification and liquidity needs can override a marginally higher after-tax yield for a client with a short time horizon or concentrated risk.
An individual owns rental real estate with a $40,000 current loss, actively participates, and has modified AGI of $120,000. No real estate professional facts are given. How much of the loss can offset nonpassive income this year?
A taxpayer has a passive rental loss and significant dividend income from a brokerage account. No exception is supplied. What is the correct TCP treatment?
A client weighs a 3.5% tax-exempt municipal bond against a 5.0% taxable corporate bond and is in a 37% marginal bracket. On an after-tax yield basis alone, which is better and why?
