What it means
Ordinary income covers the earnings a business or individual generates by doing what they normally do. For a company that means revenue from trading less the allowable costs of that trading, and for a person it means wages, bonuses, freelance fees, interest and most rental income.
The category exists because tax systems treat different kinds of income differently. Selling a warehouse you have owned for a decade produces a capital gain, whereas selling the goods stored inside it produces ordinary income, and the tax bill on the same headline amount of money can differ substantially.
In practice ordinary income is calculated by starting from gross receipts and deducting the expenses incurred in earning them, subject to whatever the tax rules allow. This is why taxable ordinary income rarely matches the profit shown in the management accounts: entertaining, certain provisions and some depreciation charges may be disallowed or replaced by statutory allowances.
The concept also shapes commercial decisions that have nothing to do with accounting neatness. Owner-managers choosing between salary and dividends, businesses deciding whether to sell a division as assets or as shares, and investors weighing income funds against growth funds are all really asking how the money will be classified.
One nuance catches people out repeatedly: a gain can be reclassified as ordinary income if the tax authority decides the activity amounts to trading. Someone who buys and sells four properties a year is likely to be treated as running a property business rather than making occasional capital gains.
In practice
Real-world examples
Example 1
A bakery owner takes a $75,000 salary from her company and receives $3,000 of interest on the business savings account. Both amounts are ordinary income, taxed at her normal rates, and neither benefits from any capital gains treatment.
Example 2
A software business sells a legacy product line for $2,000,000 more than its book value. Its accountant separates that gain from the $6,400,000 of ordinary income earned from subscriptions, because the two are taxed under different rules and reported on different parts of the return.
Example 3
A landlord with six flats treats the $180,000 of rent he collects as ordinary income and deducts $70,000 of mortgage interest, repairs and agent fees against it. When he eventually sells one flat, the profit on the sale is handled separately as a capital gain.
Think of it
Ordinary income is like your regular monthly salary from your job, which you use to pay rent and buy groceries. Capital gains are like winning a prize or selling a vintage car you rarely drive.
Formula
Calculation
Ordinary income = gross revenue from normal operations - allowable operating expenses
A marketing consultancy bills $820,000 in fees during the year. It pays $410,000 in salaries, $60,000 in rent and $150,000 in other allowable running costs, a total of $410,000 + $60,000 + $150,000 = $620,000. Ordinary income is therefore $820,000 - $620,000 = $200,000.
Assume an ordinary tax rate of 24%. Tax on the trading profit is $200,000 x 24% = $48,000. In the same year the firm sells an office it has owned for eight years, producing a capital gain of $50,000 taxed at 15%, which is $50,000 x 15% = $7,500. Total tax is $48,000 + $7,500 = $55,500, even though the two amounts of profit added up to $250,000 and would have cost $250,000 x 24% = $60,000 had both been ordinary income.Case study
Seen in the real world
Thorncastle Joinery is an invented company used purely as an illustrative example. It ran a profitable workshop and, over several years, also bought three run-down commercial units, refurbished them and sold them on.
The owners assumed the property profits were capital gains and budgeted tax at the lower rate accordingly, setting aside about $90,000. Their accountant reviewed the pattern of activity and warned that buying, improving and selling on a repeated basis looked far more like a trade than an investment, which would make the whole $600,000 of property profit ordinary income and push the bill closer to $144,000.
Thorncastle restructured before the next purchase. Long-term rental units were held in a separate company with a clear intention to keep them, while refurbishment-and-sale projects were run openly as a trading activity with the ordinary income tax provided for from day one. The lesson in this fictional case is that classification follows behaviour, not the label the owner would prefer.
Watch out
Common mistakes
- Assuming every profit a business makes is ordinary income, which leads to overpaying tax on genuine long-term capital gains.
- Treating accounting profit and taxable ordinary income as the same figure, when disallowed expenses and statutory allowances routinely make them differ.
- Repeatedly buying and selling assets while expecting capital gains treatment, when the pattern of activity makes it a trade in the eyes of the tax authority.
Questions
People also ask
Is dividend income ordinary income?
It depends on the jurisdiction and the type of dividend, but many systems tax dividends under their own rules rather than as plain ordinary income.
Why does the distinction matter if the money spends the same?
Because the tax rate, the reliefs available and the timing of the charge can all differ, which changes how much of the profit you actually keep.
Does ordinary income include interest earned on a business bank account?
Yes, interest is normally ordinary income and is taxed at standard rates rather than as a capital gain.
