Ordinary Income Tax is the primary tax that governments levy on the earnings of individuals and corporations. For most people, it's the tax on their wages, salaries, and bonuses. For investors, however, it's a crucial concept because it also applies to specific types of investment returns, often at much higher rates than other investment taxes. This category includes interest from bonds and savings, dividends that don't meet certain criteria, and, most importantly, the profits from selling an investment held for a short period. Unlike the preferential rates for long-term investments, ordinary income is typically taxed using a progressive system of tax brackets. This means that as your income increases, the tax rate on your next dollar of income also increases. Understanding which of your investment gains will be hit with this tax is fundamental to smart, tax-efficient investing.
Think of tax brackets like a series of buckets. As you fill one bucket with income, any additional income spills over into the next bucket, which has a higher tax rate. For example, in the US, the first slice of your taxable income might be taxed at 10%, the next slice at 12%, the slice after that at 22%, and so on. This is a progressive tax system. It's important to remember that you don't pay the highest rate on all your income—only on the portion that falls into that highest bracket. These brackets and rates are set by tax authorities like the Internal Revenue Service (IRS) in the United States or national revenue services in European countries. They are typically adjusted annually for inflation and vary based on your filing status (e.g., single, married filing jointly).
For a value investor, the real question is: “Which of my hard-earned profits will be taxed at these higher rates?” The answer is critical for calculating your real, after-tax returns. Here are the main culprits:
As a value investing enthusiast, your goal is to maximize long-term, after-tax returns. That means making ordinary income tax your friendly foe—something to be understood and strategically managed, not feared.
The difference between ordinary income tax rates and long-term capital gains rates can be substantial. For a high-earner, the top ordinary income rate can be nearly double the top long-term capital gains rate. This difference creates what's known as tax drag—the silent erosion of your portfolio's growth due to taxes. An investment that looks great on paper can become mediocre once the tax man takes his larger-than-expected cut. For instance, a 10% gain from a stock held for 11 months will net you significantly less than the same 10% gain from a stock held for 13 months.
The good news is that with a little planning, you can minimize the bite of ordinary income tax. This is where the wisdom of investors like Warren Buffett, who famously focuses on after-tax returns, truly shines.
