401(k), in classroom words

A U.S. workplace savings plan named after a line in the tax code. Pretax and Roth are timing words, not a pick. A match is employer money with rules. We do not roll it over. We do not pick a fund. Look. Do not buy.

A dotted mark is a word. Tap it if the meaning is new.

It is a line in a tax code, not a stock

401(k) is a U.S. workplace plan. The name is a section of the Internal Revenue Code, not a , not a coin, and not a product this classroom sells. If someone tells you they “bought a 401k,” they usually mean they deferred a paycheck into a plan at work. That is a habit with a document. It is not a on this .

We’ll open this slide when you come back. This device remembers it.

Congress wrote the section in the Revenue Act of 1978 to deal with cash-or-deferred arrangements in tax-favored plans. The IRS described the rules in 1981. A date in a statute is a record. It is not a reason to raise your deferral this afternoon because a thread said so.

ERISA — a 1974 U.S. law about employee benefits — is the other spine. Your own deferrals are generally yours. Employer money can vest on a calendar. The plan document, the SPD (the summary you are supposed to be able to read), and a licensed person beat a video. We are not your plan administrator. We will not file a form. We will not pick a fund.

A little human: naming a savings habit after a paragraph in the tax code is a very American joke, and it is still the joke we are stuck with. Laugh once. Then read the document. Passing this path is not tax advice. Look. Do not buy.

Say it back below. Then the next lesson opens. If you leave the page, we will ask to save your spot.

LOOK DON'T BUY

Real World Markets is a classroom. We only teach — stocks, crypto, and how markets work. You can look at delayed last. You cannot buy here. We do not take orders or hold money. Not a broker. Not a CASP. Lessons are free.

Delayed public last when the feed is up — a number to look at, never a ticket. Paper results are hypothetical and have no cash value. Not a broker-dealer. Not a CASP or money transmitter. You cannot buy here.

Passing a quiz is not a qualification or a license. The Professor will not tell you what to buy. Company names and tickers belong to their owners. We draw letter marks, not official logos. Not affiliated with Apple, Nasdaq, S&P, Yahoo, CoinGecko, or CoinMarketCap.

This classroom does not give financial advice. We do not tell you what to buy, sell, or hold. A lesson, delayed last, a paper fill, a quiz, Professor Moon, and a quote on the tree are teaching — not a recommendation, not a personalized plan, and not a reason to place a live order. We only teach. Educational classroom only. Not a seller. Not a market we operate. Not investment advice, not legal advice, not an offer to buy or sell, not a broker-dealer, investment adviser, CTA, or CIRO/CSA registrant. Not a CASP, VASP, MSB, money transmitter, or gambling operator. We do not custody, exchange, or transmit crypto-assets. We do not file a license for you. Not registered with the U.S. SEC, FINRA, CFTC, NFA, FinCEN, Canada’s CSA/CIRO, or Mexico’s CNBV. Last may be a delayed public print when the feed is up, or a teaching path if it is not — never a reason to trade. Options premiums and NFT floors are teaching numbers. Paper results are hypothetical and have no cash value. World Circuit is a paper board game, not gambling and not a live market. Past or simulated performance is not indicative of future results. CFTC Rule 4.41. Third-party names stay with their owners. Letter marks, not official logos.
