Imagine you are enjoying a crisp afternoon walking through the North Carolina Botanical Garden or strolling down Franklin Street in Chapel Hill. You look down and spot a five-dollar bill tucked near a park bench. After a quick glance around to see if a fellow passerby dropped it, you realize it is yours to keep. While this feels like a small stroke of luck, it actually triggers one of the most foundational concepts in federal tax law.
Under Internal Revenue Code (IRC) Section 61, the definition of gross income is remarkably broad: "gross income means all income from whatever source derived." This single sentence serves as the backbone of the American tax system. It suggests that nearly every form of economic gain, regardless of how it was acquired or how small the amount, is technically subject to taxation. This includes that five-dollar bill you found on your walk.
The IRS operates on the logic that if you receive something—whether it is a tangible stack of cash or an intangible benefit—that increases your net wealth, it likely constitutes taxable income. The randomness of a discovery does not provide a legal shield against the tax code. From a technical standpoint, that small "found fortune" is supposed to be reported on your annual tax return.
Of course, the practicality of reporting a five-dollar find is a common point of discussion among taxpayers. The IRS generally does not deploy resources to track negligible amounts like this, recognizing the administrative nightmare it would create for both the agency and the taxpayer. However, for small business owners in Chapel Hill, understanding this principle is vital because it highlights just how comprehensive the tax code is. At Adkin CPA, we often remind our clients that the "all-inclusive" nature of Section 61 is why meticulous bookkeeping is so critical for their business success.

The principle that all income is taxable applies even when the source of that income is illicit. This specific facet of IRC Section 61 has historically been used as a powerful tool for justice. The most famous example is that of the notorious mob boss Al Capone. While law enforcement struggled to convict Capone for his more violent or organized criminal enterprises, the IRS eventually secured his downfall.
During the early 20th century, Capone amassing a massive fortune through bootlegging and gambling. Because he failed to report these illegal earnings, federal agents—led by Eliot Ness and his team—used tax evasion as the primary vehicle for his arrest. The government successfully argued that under Section 61, his illegal gains were gross income, and his failure to pay taxes on them was a federal crime.
This serves as a stark reminder that the IRS definition of income is indifferent to the legality of the source. Whether it is found money or "ill-gotten gains," the obligation to report stays the same. For the modern taxpayer, this underscores the reality that the tax code is a robust instrument designed to ensure financial accountability across the board.
While the reach of Section 61 is expansive, the tax code also provides specific "safe harbors" or exclusions. These reflect deliberate social and economic policies designed to provide relief in specific circumstances. At Adkin CPA, helping our clients identify these exclusions is a key part of our tax planning services. Here are some of the most common sources of income that are not taxable:

We have all seen the scenes on television: a contestant is overcome with joy as they win a luxury car or a high-end vacation. While these moments make for great entertainment, the tax reality that follows can be quite sobering. Winners are required to pay taxes on the Fair Market Value (FMV) of their prizes.
Consider the logistical hurdles that come with these winnings:

Beyond the common examples of cash and physical prizes, the tax code also addresses more obscure forms of wealth acquisition through the "Treasure Trove" doctrine. This legal concept was solidified in the famous court case of Cesarini v. United States, where a couple purchased a second-hand piano and later discovered several thousand dollars in old currency hidden inside the frame. While the finders argued the money should be exempt, the court ruled that the value was taxable in the year it was reduced to "undisputed possession." For residents in the Research Triangle, this means that any significant discovery made in a purchased item—whether it is a rare coin found in an antique desk from a Chapel Hill estate sale or a valuable piece of art hidden behind a thrift store painting—is technically gross income that must be reported to the IRS at its fair market value.
Another area where "found money" often surprises small business owners is in the realm of bartering and trade exchanges. In a vibrant local economy like North Carolina's, it is not uncommon for a graphic designer to trade their services for furniture from a local maker, or for a marketing consultant to swap work for a credit at a neighborhood coffee shop. Although no physical cash changes hands, the IRS views these trades as taxable events. Each party must report the fair market value of the services or goods they received as business income. At Adkin CPA, we work with our clients to ensure these non-cash transactions are recorded properly in their bookkeeping systems, preventing unexpected liabilities that could arise if these "hidden" gains are discovered during an audit. Understanding the fair market value of a trade is essential to maintaining a clean set of books and a clear tax position.
The digital landscape has introduced a modern version of found wealth in the form of cryptocurrency airdrops and hard forks. An airdrop occurs when a blockchain project distributes free tokens to the wallets of existing crypto holders, often as a marketing tactic. A hard fork happens when a blockchain splits, resulting in the creation of a new type of coin for everyone who held the original currency. According to IRS Revenue Ruling 2019-24, these events represent an "accession to wealth" and are treated as ordinary income at the moment the taxpayer gains control over the new assets. For tech-focused professionals in our region, tracking these digital windfalls is critical, as the value is determined by the trading price at the exact time of receipt, regardless of whether the tokens are ever sold for US dollars.
It is also important to distinguish between a casual windfall and awards received in a professional setting. While a five-dollar bill found in a park is a simple discovery, prizes or "found" value from an employer are almost always treated as taxable wages. If a local business offers a "spot bonus" or a prize for a sales competition, that value is subject to income tax withholding and FICA taxes. Even "de minimis" gifts, like a holiday turkey, have specific rules, and larger non-cash items must be included on the employee's W-2. This transparency is vital for both the employer and the employee to avoid penalties for underreporting compensation. By staying informed about these various categories of unexpected income, you can better manage your financial future and avoid the stress of tax season surprises.
