Filing Short or Long Form Schedule SE for Self-Employment Tax
Self-employment tax is collected for Social Security and Medicare
Remember that old saying that the only two things in life that are certain are death and taxes? Self-employment tax is based on the income of a business owner and it's collected for Social Security and Medicare. Schedule SE calculates the amount of self-employment tax owed by a business owner based on the profit or loss of his business during the tax year. It includes both a short form and a long form.
Income From Self-Employment vs. Employment
Everyone pays Social Security and Medicare taxes, but how much and how you do it differs depending on whether you're self-employed or you work for someone else.
Most people work for someone else so their Social Security and Medicare taxes are collected from their earnings. They pay half and their employers match their contributions, paying the other half. But a self-employed business owner doesn't get a paycheck from someone else that this money can be withheld from, and he doesn't have an employer to match the half he pays personally. He has to pay the full amount himself...sort of.
Who Is Considered Self-Employed for Tax Purposes?
Self-employed business owners include sole proprietors or single-member limited liability companies (LLCs) They include partners who must pay self-employment tax on their share of partnership income. Members in multiple-member LLCs are considered partners for federal tax purposes.
Calculating Self-Employment Tax on Schedule SE
You must first determine the net income from your business—or, if you own several businesses, from all of them added together. Your net profit is calculated on Schedule C. It's your overall revenues less your qualifying business expenses. You can move on to Schedule SE for self-employment taxes when you've determined this number.
Next you must calculate the amount of the deduction for self-employment tax to be entered on line 27 of your Form 1040. Yes, that's right. You get a tax deduction for half your self-employment tax, which eases the sting considerably of having to pay both the employer's and the employee's half. This deduction is entered on page one of your tax return so it reduces your adjusted gross income—your net taxable income before you take other deductions.
The amount of self-employment tax is calculated next. The total net profit from all your businesses is considered, but only the first $128,700 is taxable for Social Security purposes as of 2018. The ceiling was $127,000 for the 2017 tax year.
Long Form and Short Form Calculations
If you had no income all year other than your self-employed income and you meet certain other qualifications, you might be able to complete the short form, which is Section A. Otherwise, you must complete the long form, Section B.
Documents You'll Need
You'll need a copy of Schedule SE, which can be downloaded from the IRS website. You can complete the form online, save it, and print it out.
You'll also need a completed Schedule C for each of your businesses, as well as copies of any W-2 forms you might have for the year if you also worked for someone else and Social Security and Medicare taxes were withheld from your paychecks. Your W-2 forms will show how much in the way of Social Security and Medicare taxes compensation you paid. You'll find this information in boxes 4 and 6.
You'll also need your individual income tax form, IRS Form 1040.
How to Complete the Short Form of Schedule SE (Section A)
You can start with line 2 if you have none of the income that's described in lines 1(a) or 1(b). Enter the net income from your Schedule C. If you have more than one Schedule C, total the net incomes from all of them and enter that number. Add that to line 1 if you entered anything there and put the result on line 3.
Multiply line 3 by 92.35 percent and enter the result on line 4. If the result is less than $400, you don't owe self-employment tax.
Calculate your self-employment tax on line 5. If it's $127,200 or less, multiply line 4 by 15.3 percent. If it's more than $127,200, multiply line 4 by 2.9 percent then add $15,772.80 to the result.
You must now include the self-employment tax calculation on your Form 1040. Enter the result from line 5 on Form 1040, Line 57. Multiply line 5 by 50 percent and enter the result on line 27 of your 1040 and on line 6 of Schedule SE.
How to Complete the Long Form of Schedule SE (Section B)
This section is the self-employment tax calculation for individuals who have income in addition to self-employment income. The calculation combines FICA taxes—Social Security and Medicare tax—you already paid on your other income and those you owe on your self-employment income to determine the self-employment tax owed.
On line 1, enter your net farm income 1(a) and/or Social Security income 1(b) if you have any and total them. Then, on line 2, enter your net income from Schedule C. Total lines 1 and 2 on line 3.
On line 4(a), multiply line 3 by 92.35 percent. If the result is less than $400, you don't owe self-employment tax. Include the FICA tax that you've already paid on wages to determine if any self-employment tax is owed.
Subtract line 8(d) from line 7, the Social Security maximum amount, and enter this on line 9. If it's zero or less than zero, just enter that and jump to line 11.
If it's more than zero, multiply the smaller of line 6 or line 9 by 12.4 percent on line 10. Multiply Line 6 by 2.9 percent on line 11.
Now you can Include your self-employment tax calculation on Form 1040. Add lines 10 and 11 and enter the result on Line 12 and on Form 1040, line 57.
Line 13 is the deduction for one-half of your self-employment tax. Multiply line 12 by 50 percent and enter the result on line 27 of your Form 1040.
When You File Schedule SE
The Schedule SE calculation is entered on IRS Form 1040 in two places.
Line 27, which reduces your adjusted gross income by half of the self-employment tax amount
Line 57 to include the total self-employment tax owed in addition to personal income taxes. The amount on Line 57 is added to your personal income tax calculation along with some other taxes to show your total federal tax liability for the year.
Schedule SE is admittedly a challenge, but you can take comfort in knowing that some tax forms are actually worse. The IRS also includes helpful directions on each line of Schedule SE to guide you step by step.
Don't neglect to include the schedule when you file your tax return.
These instructions are for relatively simple self-employment situations. You might want to consult a tax professional if your situation is more complicated.
