Short-Term vs Long-Term: The $47K Difference Nobody Calculates

Sell a stock after 11 months: 37% tax rate. Sell the same stock one month later: 20% tax rate. On a $100,000 gain, that one-month difference costs you $17,000. Most investors don't track holding periods. They should.

The Rate Gap

Short-term capital gains (assets held less than 1 year) are taxed as ordinary income. Long-term capital gains (held more than 1 year) get preferential rates. The difference is dramatic:

Add the 3.8% Net Investment Income Tax for incomes above $200,000 (single) and the effective long-term rate becomes 23.8%. Still dramatically less than the 40.8% effective short-term rate at the top bracket.

The $47,000 Scenario

Here's a concrete example. You're in the 32% bracket and sell a position with a $275,000 gain:

• Sold at 11 months (short-term): $275,000 x 35.8% (32% + 3.8% NIIT) = $98,450 in taxes
• Sold at 13 months (long-term): $275,000 x 18.8% (15% + 3.8% NIIT) = $51,700 in taxes
• Difference: $46,750. For waiting 60 days.

That's not a rounding error. That's a used car. And many investors make this trade without checking their holding period because they don't have it visible anywhere.

When Selling Short-Term Is Rational

Waiting for long-term treatment isn't always the right call:

• The position is declining rapidly.If a stock is down 30% and falling, waiting 2 months for long-term treatment means risking further losses. A 17% tax savings doesn't justify a 20% price decline.
• You need the cash. If you have a short-term use for the money (down payment, emergency, business expense), the tax cost of selling early may be worth the opportunity cost of waiting.
• You're in a low bracket. At the 12% ordinary income rate, the difference between short-term (12%) and long-term (0%) is only 12%. The dollar amount on a small gain may not justify the risk of holding.

The Crypto Wrinkle

The same short-term vs long-term distinction applies to crypto. Bitcoin held for 11 months and sold at a gain is short-term. Held for 13 months, it's long-term. But crypto is more volatile than stocks, which means the trade-off between holding for long-term treatment and protecting gains is sharper.

A common crypto tax mistake: swapping tokens on a DEX without realizing the swap is a taxable sale. If you bought ETH 10 months ago and swap it for USDC today, that's a short-term gain on the ETH — even though you didn't sell for dollars.

How Clarity Tracks This

Clarity shows the holding period and tax-lot status of every position across all your connected accounts. Positions approaching the 1-year threshold are flagged so you can make an informed decision about timing. The tax view shows your total short-term and long-term gains side by side, so you see the real dollar impact of selling now vs waiting.

The bottom line: the short-term vs long-term distinction is the single biggest tax variable most investors can control. It requires no fancy strategy, no tax lawyer, no special accounts. Just knowing your holding periods and making selling decisions accordingly.
