You pay taxes on your net profit (or taxable income), not your gross profit, because it's the money left after deducting legitimate business expenses (like COGS and operating costs) from your total revenue, representing your actual earnings. However, employees are taxed on their gross income (wages before deductions), while businesses deduct expenses from gross revenue to find their taxable net income.
However, gross vs net income is slightly different for tax purposes depending on whether you're an employer or an employee: Employers pay tax on net income. Employees pay tax on gross income.
Determine the total revenue generated from sales. Subtract all expenses, including cost of goods sold and operating expenses, from the total revenue to get the gross profit. Subtract other expenses such as interest payments and taxes from the gross profit to get the net profit.
The federal individual income tax has seven tax rates ranging from 10 percent to 37 percent (table 1). The rates apply to taxable income—adjusted gross income minus either the standard deduction or allowable itemized deductions.
Gross pay is what employees earn before taxes, benefits and other payroll deductions are withheld from their wages. The amount remaining after all withholdings are accounted for is net pay.
Computing taxable income
Taxable income can be calculated by adjusting all the available deductions and exemptions such as Leave Travel Allowance (LTA), House Rent Allowance (HRA), etc. that are part of your gross salary.

On a £23,000 salary, your take home pay will be £20,079.60 after tax and National Insurance. This equates to £1,673.30 per month and £386.15 per week. If you work 5 days per week, this is £77.23 per day, or £9.65 per hour at 40 hours per week.
You'll pay tax on your net profits, whether you're a limited company or sole trader. Get confused between these and your gross figures, and you'll pay a lot more tax than you need to.
Gross income is the total amount of income you receive from all sources before any taxes or other deductions are taken out. Adjusted Gross Income (AGI) is used in completing your tax return and is all of the taxable income you bring in, minus certain adjustments.
The net income of the sole trader business is included with any other income of the owner and taxed at the marginal rate of tax. In contrast, a company has a more complex business structure and is its own separate legal entity. From a tax perspective, companies pay tax on its profits at the corporate tax rate.
Small business owners pay two types of taxes: personal taxes on the income they earn through their business and small business taxes on the company's financial activities. Unlike personal taxes, which individuals file annually, business taxes operate on quarterly payment schedules.
Employers withhold taxes from employees' pay .
Gross pay is the amount the employee earns. Net pay, or take-home pay, is the amount the employee receives after deductions.
Unreported income
The IRS receives copies of your W-2s and 1099s, and their systems automatically compare this data to the amounts you report on your tax return. A discrepancy, such as a 1099 that isn't reported on your return, could trigger further review.
Generally, a gross profit margin of between 50–70% is good and anything above that is very good. A gross profit margin below 50% is usually not desirable – though lower margins can still be sustainable for businesses with lower operating costs.
Corporation: Corporations are the only entities that pay federal taxes on their own based on net earnings.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
One of the most common tax mistakes businesses make is failing to maintain a clear separation between personal and business expenses. Mixing personal and business finances can create confusion during tax time, making it difficult to accurately track deductions and file the right amount of taxes.
Unemployment compensation generally is taxable. Inheritances, gifts, cash rebates, alimony payments (for divorce decrees finalized after 2018), child support payments, most healthcare benefits, welfare payments, and money that is reimbursed from qualifying adoptions are deemed nontaxable by the IRS.
A 20% gross profit margin means that for every dollar of revenue a business earns, it keeps 20 cents as gross profit after covering the direct costs (Cost of Goods Sold, or COGS) of producing or acquiring the goods or services sold; the remaining 80 cents goes to paying for those direct costs. This metric shows how efficiently a company converts revenue into profit before considering operating expenses, interest, and taxes.
As a self-employed individual, you pay both income tax and a 15.3% self-employment tax (Social Security & Medicare) on 92.35% of your net earnings (profit after business deductions), plus potential state income tax, requiring quarterly estimated tax payments to the IRS to avoid penalties, often setting aside 25-30% of income for taxes.
