Investment Planning makes up 17% of your CFP exam score, and within that, capital gains questions are a critical test of your integrated knowledge. Most candidates memorize the wash sale rule's 30-day window but fail when the exam presents a scenario involving options contracts or an IRA, turning a simple recall question into a complex judgment problem. This isn't just about tax; it's about proving you can apply fiduciary care across a client's entire financial life.
Capital gains management for the CFP exam is the application of strategies like tax-loss harvesting, lot selection, and direct indexing to minimize a client's tax liability on investment profits. Success requires moving beyond memorizing rules like the wash sale window to applying them in complex, multi-account scenarios.

What is Capital gains management and why it matters for the CFP exam
Capital gains management involves the strategic timing of asset sales and the use of specific techniques to reduce the taxes clients owe on their investment growth. This isn't just a tax-filing issue; it's a core component of portfolio management that directly impacts a client's net returns. For your clients, effective management can mean thousands of dollars saved annually, compounding into significant wealth over time.

On the CFP exam, these concepts are rarely tested in isolation. The Board wants to see if you can think like a planner, not just an analyst. A question might present a client with a concentrated stock position and ask for the best course of action. The answer will require you to weigh capital gains implications against diversification needs, estate planning goals, and the client's risk tolerance.
The most common mistake candidates make is treating this as a pure memorization topic. They learn the $3,000 capital loss deduction limit and the 30-day wash sale rule, then stop. The exam will punish this superficial knowledge. It will present a scenario where a client sells a stock at a loss in their taxable account and buys a similar mutual fund in their IRA two weeks later. The candidate who only memorized the rule for taxable accounts will incorrectly allow the loss, failing the question. The prepared candidate recognizes the wash sale rule applies across all of a client's accounts, including IRAs.

Key concepts and rules you must know
You must have a rock-solid understanding of the mechanics behind capital gains management. These are the non-negotiable concepts that will appear on your exam.
Tax-Loss Harvesting
This is the process of intentionally selling securities at a loss to offset capital gains realized elsewhere in the portfolio. If losses exceed gains, you can deduct up to $3,000 of the excess loss against ordinary income each year, with any remaining loss carried forward indefinitely.
The CFP exam will test your judgment here. Is it always wise to harvest a loss? No. For a client in the 0% long-term capital gains bracket, harvesting a loss to offset a long-term gain has no tax benefit. The examiner wants to see if you can make that distinction.
The Wash Sale Rule (IRC § 1091)
The wash sale rule is the examiner's favorite tool for separating candidates who know the rules from those who understand the application. The rule states that if you sell a security at a loss, you cannot deduct that loss for tax purposes if you purchase a "substantially identical" security within 30 days before or 30 days after the sale.
The disallowed loss is not gone forever. It is added to the cost basis of the new, replacement shares. This defers the tax benefit of the loss until you sell the new position.
Lot Selection
When a client sells only a portion of a position that was acquired over time, you must determine which specific shares were sold. This has a massive impact on the resulting gain or loss.
| Method | Description | Best For | Exam Implication |
|---|---|---|---|
| FIFO | First-In, First-Out. The first shares purchased are the first ones sold. This is the default method if no other is specified. | Simplicity. | Often results in the highest capital gain in a rising market, making it a poor choice for tax management. |
| LIFO | Last-In, First-Out. The most recently purchased shares are the first ones sold. (Note: Not permitted by the IRS for securities). | N/A for securities. | A classic distractor answer. If you see it as an option for selling stock, eliminate it immediately. |
| Specific ID | You specifically identify which lot of shares to sell. | Maximum tax efficiency. | This is almost always the correct answer for a client seeking to manage their tax liability. |
| Average Cost | You average the cost of all shares. This is only available for mutual fund shares and is irrevocable once chosen. | Simplicity for mutual funds. | Less flexible than Specific ID. Once elected, you cannot switch back to Spec ID for that fund. |
As a planner bound by the CFP Board's fiduciary duty (Standard of Conduct A.1), using Specific ID to harvest losses or select high-basis shares is a direct application of putting your client's interests first.

Worked example with step-by-step solution
Let's walk through a scenario that mirrors the complexity you'll face on exam day. This isn't just a calculation; it's a test of your process.
Your client, Sarah, holds the following position in a taxable brokerage account:
- 100 shares of TechCorp (TC) purchased on Jan 15, 2024, for $100/share (Basis: $10,000)
- 100 shares of TechCorp (TC) purchased on June 1, 2025, for $150/share (Basis: $15,000)
On November 15, 2026, the stock is trading at $120/share. Sarah wants to sell 100 shares to fund a home renovation. She also mentions she is bullish on the tech sector long-term. On November 30, 2026, feeling she sold too early, she buys 100 shares of TC back at $125/share.
Which of the following is the most tax-efficient strategy for the initial sale, and what is the consequence of her subsequent purchase?
This question combines lot selection and the wash sale rule. Let's break it down.
Step 1: Analyze the client's goal and select the best lot
Sarah needs cash but is bullish on the sector. The most tax-efficient strategy is to realize a loss if possible, or the smallest gain. We must use the Specific Identification method.
- Selling the January 2024 lot: Proceeds ($120 x 100) = $12,000. Basis = $10,000. This creates a $2,000 long-term capital gain.
- Selling the June 2025 lot: Proceeds ($120 x 100) = $12,000. Basis = $15,000. This creates a $3,000 short-term capital loss.
Clearly, selling the June 2025 lot is the superior choice. It generates a $3,000 loss that can be used to offset other gains or up to $3,000 of ordinary income.
Step 2: Identify the wash sale
Sarah sold her shares on November 15th for a loss. She then repurchased the same stock on November 30th. This is only 15 days later, well within the 30-day window before or after the sale.
This triggers the wash sale rule under IRC § 1091.
Step 3: Calculate the consequences
Because of the wash sale, the $3,000 loss is disallowed for the 2026 tax year.
The disallowed loss is not simply erased. It is added to the cost basis of the 100 replacement shares she purchased on November 30th.
- Purchase price of new shares: 100 shares x $125/share = $12,500
- Add the disallowed loss: + $3,000
- New adjusted basis: $15,500
Her holding period for the new shares will also tack on the holding period of the shares whose loss was disallowed.
The Tempting Wrong Answer
Many candidates would correctly identify the $3,000 loss in Step 1 and stop there. They would choose an answer that says, "Sarah should sell the second lot to realize a $3,000 short-term capital loss." This answer is correct in isolation but incomplete and therefore wrong in the context of the full scenario. The exam is testing your ability to see the full sequence of events, not just the initial transaction. You must account for the repurchase to arrive at the correct final outcome.
Practice questions: test yourself on Capital gains management
Theory is one thing; performing under pressure is another. Here are a few sample questions modeled after what you'll see on the exam. VoraPrep has over 6,900 questions in its adaptive QBank to help you master these concepts.
Question 1
Susan holds a large, highly appreciated stock position in her taxable account and wants to protect her unrealized gains from a potential market downturn while deferring capital gains tax. Which of the following strategies is most appropriate?Explanation: The correct answer is B. A protective put gives Susan the right to sell her stock at a predetermined price, setting a floor on her potential losses while allowing her to retain ownership and participate in any future upside. Selling the stock (A) would immediately trigger capital gains. Gifting the stock (C) transfers her cost basis to her son, so the tax is still due when he sells. Shorting against the box (D) was a strategy to lock in gains and defer taxes, but the Taxpayer Relief Act of 1997 largely eliminated this benefit by creating a "constructive sale" rule.
Question 2
Maria and her financial advisor are reviewing her taxable brokerage account in November. They notice several positions with unrealized losses. Maria has already realized $10,000 in short-term capital gains this year. Her primary goal is to minimize her 2026 tax liability. What should the advisor recommend?Explanation: The correct answer is C. Maria can use capital losses to offset capital gains without limit. After offsetting the $10,000 in gains, she can then deduct an additional $3,000 of losses against her ordinary income. Therefore, harvesting a total of $13,000 in losses provides the maximum tax benefit for the current year. Any loss beyond $13,000 would be carried forward.
Question 3
Kenji, age 55, sold 500 shares of an S&P 500 index fund at a loss in his taxable account on October 10th. On October 25th, his 401(k) plan, which he directs, automatically purchased shares of a different S&P 500 index fund as part of his bi-weekly contribution. What is the tax consequence of these transactions?Explanation: The correct answer is D. The wash sale rule applies across all of a taxpayer's accounts, including retirement accounts like IRAs and 401(k)s. Even though the funds are from different issuers, they track the same index and are considered "substantially identical." The fact that the purchase was automatic is irrelevant. The loss is disallowed, and because the replacement shares are in a tax-deferred account (the 401k), the basis step-up benefit is permanently lost. This is a severe penalty and a classic exam trap.

Study tips and exam-day strategy
Capital gains management isn't a topic you can cram. It requires integrating rules from tax planning with portfolio management theory.
Focus on Connections: Don't study this in a vacuum. When you review capital gains, ask yourself how it connects to other areas. How does it impact charitable giving strategies? How does it affect the choice between a mutual fund and an ETF? How does it relate to the asset location decision (what to hold in taxable vs. tax-advantaged accounts)? Seeing these connections is the key to answering higher-level case study questions. For instance, understanding tax implications is crucial for topics like those in our CFP Tax Planning: IRS audit procedures — Complete Study Guide. Draw it Out: For complex wash sale or lot selection problems, use your scratch paper. Draw a timeline. Write down the purchase dates, sale dates, prices, and share counts. A simple visual can prevent you from making a costly mental error under pressure. Final Week Review: In the last week before your exam, don't try to learn new concepts. Instead, focus on the application of rules you already know. Redo practice questions you got wrong, paying close attention to the why in the explanations. Your goal is to solidify your decision-making process, not just your memory.
