What Is Self-Employment Tax
So you’ve decided to go achieve the American dream by becoming your own boss. Your new business is taking off after lots of hard work and everything is going awesome. Come tax season, you go to your accountant, who congratulates you on your newfound success and then informs you that you now owe the government even more money for being in business for yourself.
You’ve just discovered what is known as the self-employment tax
Created in 1954 by the Self-Employment Contributions Act (SECA), this tax law requires self-employed individuals of small businesses to pay 15.3% of their net income towards Social Security and Medicare.
Normal employees and employers also pay the same 15.3% towards Social Security and Medicare as outlined by the Federal Insurance Contribution Act (FICA) of 1935, only their version is split in half with the employer paying 7.65% and employee paying 7.65%.
Since you are your own employer, aka self-employed, you are now also responsible for the employer’s portion.
Who Must Pay Self-Employment Tax in 2019?
Those who may be subject to self-employment tax include partnerships, limited liability corporations, sole proprietorships, and farmers.
LLC members may or may not be subject to the self-employment tax depending on if they’ve elected to treat the LLC as a C or S corporation. By default, a single member LLC is treated as a sole proprietorship, and a LLC with more than one member is treated as a partnership.
Even if you earn wages from an employer, if you have made $400 or more a year in a side business of your own, you still need to pay self-employment taxes on the profits from your business.
Since the amount of tax you must pay is calculated from your business’ net profits, it is to your benefit to deduct any and all business expenses used to generate your business income.
The self-employment tax applies no matter your age, even if you are retired and receiving Medicare and Social Security benefits. This is also true even if you are a digital nomad living in Thailand for most of the tax year and you qualify for the foreign earned income exclusion.
How To File Self-Employment Tax
When filing your annual taxes, you will use the Schedule C of the Form 1040 to calculate your net profit or loss from self-employment. This number is derived from your gross income minus all your business expenses and deductions.
Your net profit amount from the Schedule C will then be used in the Schedule SE of Form 1040 to calculate how much self-employment tax you owe.
Those who are married and file a joint tax return with a spouse who is also self-employed will need to calculate each person’s self-employment tax obligations separately.
In addition to filing your taxes by April 15, as a self-employed person, you are expected to pay estimated taxes quarterly. This is done by using Form 1040-ES, Estimated Tax for Individuals. Estimated taxes are expected by the IRS because you do not have an employer to withhold taxes from your income during each pay period like traditional employment. You have the option to either estimate your taxes each quarter from that quarter’s income or dividing your previous year’s total tax by four and making four equal payments.
What Are The Self-Employment Tax Rates and Limits for 2019
The below table shows the Medicare and Social Security tax rates for 2019
The law sets the maximum earnings subject to the Social Security tax. This ceiling has steadily increased over the years.
For the 2019 tax year, the maximum amount that is taxed for Social Security is $132,900.
Any wages and earnings over this amount will not be subject to the 12.4% tax. For 2019, the most you will pay for the Social Security portion is $16,479.60.
For the Medicare portion of the self-employment tax and FICA, all wages from traditional employment and business earnings are taxed at 2.9%. There is no tax cap like the Social Security portion.
Under the Affordable Care Act, there is an additional 0.9% Medicare tax for income, wages, and compensation that exceed $200,000 if you are single, a head of household, or a qualifying widow(er) with dependent child. The income threshold for married filers is $250,000 (or $125,000 if married and filing separately).
This means that if you are single and earn $250,000 a year, the first $200,000 in earnings is taxed at 2.9%. The remaining $50,000 will be subject to the 0.9% surtax for a total tax of 3.8%. Your total Medicare tax bill will be approximately $7,000 after accounting for the deductible employer’s portion of the self-employment tax. The steps to calculate your additional Medicare tax can be found in the IRS Form 8959.
