Compute self-employment tax on Schedule SE (Form 1040). When figuring your adjusted gross income on Form 1040, Form 1040-SR, or Form 1040-NR, you can deduct one-half of the self-employment tax. You calculate this deduction on Schedule SE (attach Schedule 1 (Form 1040), Additional Income and Adjustments to Income PDF).
The self-employment tax rate is 15.3 percent: 7.65 percent for the employee portion and 7.65 percent for the employer portion. The 15.3 percent reflects a 12.4 percent levy for Social Security and 2.9 percent levy for Medicare.
The IRS permits some self-employed individuals to deduct up to 20% of their qualified business income (QBI), as well as 20% of qualified real estate investment trust (REIT) dividends and qualified publicly traded partnership (PTP) income.
Income tax rates for the self-employed are exactly the same as the rates paid employed people. But there is a difference. The self-employed only pay income tax on profits, not total earnings like salaried people.
Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
Choose the Right Business Structure
Sole proprietors and single-member LLCs pay full self-employment tax on all profits. However, if your income exceeds a certain threshold, switching to an S Corporation (S-Corp) could significantly reduce your SE taxes.
– If You Pay for Your Phone Plan: If you are an employee and you pay for your mobile phone expenses without reimbursement from your employer, you can claim the work-related portion of your bill on your tax return.
For self-employed individuals, rent and lease payments can often be written off as business expenses. This means that these costs can be deducted from your taxable income, reducing your overall tax liability.
You qualify for the 20% pass-through deduction (QBI deduction) if you own sole proprietorships, partnerships, S corporations, or some LLCs, trusts, and estates, allowing up to 20% of your Qualified Business Income to be deducted from your taxes, but the deduction phases out and has restrictions (like W-2 wages and property limits) for higher-income earners, especially in Specified Service Businesses (SSBs).
The biggest tax mistakes people make include filing late, math errors, incorrect personal info (like Social Security numbers), forgetting deductions/credits (like EITC), misreporting income, not signing forms, and making errors with bank details for direct deposit, all leading to delays, penalties, or missed savings, with using tax software or professionals helping avoid these common pitfalls.
Home mortgage interest. Income, sales, real estate and personal property taxes. Losses from disasters and theft. Medical and dental expenses over 7.5% of your adjusted gross income.

Self-employment tax deduction
The IRS lets you deduct half of the 15.3 percent self-employment tax (which covers social security and medicare taxes), so 7.65 percent—the same amount you would deduct if you were an employer. Plus, you'll lower your taxable profit with the more deductions you're able to claim.
To maximize your deductions, you'll have to have expenses in the following IRS-approved categories:
Yes, you can deduct your business meals – but as we always say, there are conditions that must be met. Under normal circumstances, qualifying business meals are 50% deductible.
Forming an S Corporation can reduce your self-employment tax liability by allowing you to pay yourself a reasonable salary and distribute the remaining profits to yourself, which aren't subject to employment taxes.
The exemption is automatic and if your self-employed income is £1,000 or less, you do not need to tell HMRC or file a tax return. For example, if you have a small gardening business and your income for the year is £900, this is covered by Trading Allowance and you will not need to pay tax on it or report this to HMRC.
Simply being self-employed subjects one to a separate 15.3% tax covering Social Security and Medicare. While W-2 employees “split” this rate with their employers, the IRS views an entrepreneur as both the employee and the employer. Thus, the higher tax rate.
