Question 1 of 12

What is a capital gain?

Capital gains tax rules — the difference between short and long-term rates, how cost basis works, and what happens to inherited assets — trip up even experienced investors. This 12-question quiz checks your grasp of these fundamentals. It takes about 3 minutes, with an explanation after every answer.

Once you've tested your knowledge, estimate your actual tax liability on a specific sale with the Capital Gains Tax Calculator, or see how it affects your overall refund with the Tax Refund Estimator.

Frequently Asked Questions

How is my score calculated?

Each of the 12 questions has exactly one correct answer, and your final score is the number you got right out of 12. There's no partial credit, so read each option carefully.

Is my quiz result saved anywhere?

No. The quiz runs entirely in your browser and nothing is sent to a server or stored. Refreshing the page resets your progress.

Why does the one-year holding period matter so much?

Crossing from short-term to long-term status can shift your gain from being taxed at your ordinary income rate to the generally lower long-term capital gains rate, which can mean a meaningfully smaller tax bill for the same dollar amount of gain.

How do I estimate the tax I'd owe on a specific sale?

The [Capital Gains Tax Calculator](/capital-gains-tax-calculator/) estimates your tax liability based on your gain amount, holding period, and income level, helping you plan before you actually sell.

How do I see how a capital gain affects my overall tax refund or balance due?

The [Tax Refund Estimator](/tax-refund-estimator/) projects your overall refund or amount owed for the year, factoring in income, withholding, and other tax events like a capital gain.

Is tax-loss harvesting something I need a financial advisor to do?

It can be done independently by selling at-a-loss positions before year-end to offset gains elsewhere, though a tax or financial professional can help navigate rules like the wash-sale rule, which disallows the loss if you buy back a substantially identical investment too soon.

Do I need investing experience to take this quiz?

No prior experience is needed. The questions are written for a general audience and every explanation avoids unnecessary jargon.

Can I retake this quiz?

Yes, any time — it's a good way to confirm concepts like cost basis and the stepped-up basis rule have actually stuck.
