Gross income is all the money your business takes in before any expenses. Net income is what's left after you subtract your business expenses, and it's your actual profit. The most important thing to know: as a self-employed person, you are taxed on your net income, not your gross. Mixing up the two is how people end up shocked by their tax bill.
These two words get used all the time loosely, but the difference between them decides what you owe and what you actually keep. Here is the plain version.
Gross income: everything that comes in
Your gross income is the total of all payments your business receives before you take anything out. Every client invoice paid, every Stripe payout, every deposit, added up across the year. If you brought in $90,000 from your work, your gross income is $90,000.
Gross is the big, satisfying number. It is also the one that fools people, because it is not money you get to keep, and it is not the number your taxes are based on. It is just the starting point.
Net income: what's left after expenses
Your net income is your gross income minus your business expenses. It is your profit, the real measure of what your business earned.
Say your gross income is $90,000 and you spent $20,000 running your business that year, on software, a home office, professional development, mileage, and the rest. Your net income is $70,000. That $70,000 is the number that actually matters, because it is what you are taxed on and the truest picture of what your work produced.
The gap between the two is your expenses, which is exactly why tracking every deductible expense matters so much. Every legitimate expense you capture lowers your net income, and a lower net income means a lower tax bill.
The worked example
Put it together, and the flow is simple:
- Gross income: $90,000 (everything that came in)
- Minus business expenses: $20,000
- Net income (profit): $70,000
Your income tax and your 15.3 percent self-employment tax are both calculated on that $70,000 net figure, not on the $90,000 you originally brought in. If you had not tracked that $20,000 in expenses, you would be taxed as if you earned the full $90,000, and you would overpay on money you already spent running your business.
Why the difference matters so much
Two costly misunderstandings come from blurring these two numbers.
Thinking gross is what you're taxed on. Some people mentally set aside taxes against their gross income, or worse, do not set anything aside and assume the bill will be small. When you understand that tax is based on net, you can see why capturing expenses is not just tidy bookkeeping. It directly shrinks the number you owe.
Thinking net income is your take-home pay. This is the second trap. Your net income is your profit, but it is not what you get to keep, because you still owe taxes on it. From that $70,000 net income, you still set aside income tax and self-employment tax. Your actual take-home is net income minus the taxes you owe. Treating your full profit as spendable is what makes the quarterly or April bill a scramble.
So there are really three numbers worth keeping straight: gross (what came in), net (your profit, what you're taxed on), and take-home (what's left after taxes). Confusing any two of them leads to a surprise.
Which number do you actually use?
Different situations ask for different figures, which adds to the confusion:
- For taxes: your net income. This is what income tax and self-employment tax are calculated on.
- For "how much did I make": net income is the honest answer, because gross ignores what it cost you to earn it.
- For loans or mortgages: lenders often look at your net income, since that is your provable profit, though requirements vary. This is one reason underreporting expenses to inflate your gross can backfire.
When someone asks what you earn, gross sounds bigger. But net is the number that runs your life and your taxes.

Frequently asked questions
Are you taxed on gross or net income when self-employed?
Net income. Your income tax and the 15.3 percent self-employment tax are calculated on your profit after business expenses, not on your total revenue. This is why tracking deductible expenses lowers your tax bill.
Is net income the same as take-home pay?
No. Net income is your profit after business expenses, but you still owe income and self-employment tax on it. Your take-home is your net income minus the taxes you set aside, which is why saving a percentage of each payment matters.
What is the difference between gross and net income for a freelancer?
Gross income is everything your business takes in before expenses. Net income is what remains after subtracting business expenses, and it is your actual profit and the figure your taxes are based on.
