FAQs
How do self-employed individuals pay self-employment tax?
Self-employed individuals must file Schedule C along with Form 1040 to report net earnings. The Internal Revenue Service uses this information to calculate the SE tax, which includes both Social Security and Medicare taxes. Taxpayers can make quarterly estimated tax payments during the year to avoid penalties.
What is the current self-employment tax rate?
The self-employment tax rate equals 15.3 percent, covering contributions toward Social Security and Medicare. Half of this amount is deductible on the tax return, which helps reduce taxable income. These payments support eligibility for receiving Social Security benefits later in life.
Can self-employed individuals deduct health insurance premiums?
A taxpayer may deduct health insurance premiums paid for the taxpayer, a spouse, and dependents. This deduction lowers taxable income and may help the filer qualify for other tax benefits. It applies only to the portion not paid through an employer’s plan.
What if a small business reports a net loss?
A net loss occurs when business expenses exceed income earned. The amount may offset other taxable income, which could lower overall income tax liability. Recordkeeping remains essential because the IRS limits deductions according to total income and filing status.
