Self-employment tax on a 4-field $400 note

• Before you calculate the tax, verify the client’s net earnings against the $400 threshold.
• If the client’s earnings fall below this amount, the calculation stops.
• The tax rate consists of two distinct parts.
• These percentages apply to the net earnings subject to tax.
• The Internal Revenue Code imposes these rates on self-employment income.

The first check in your review is the dollar amount of the client's net earnings.

Once you confirm the earnings meet the threshold, the next figure is the base for the calculation. The Internal Revenue Service notes that generally, the amount subject to self-employment tax is 92.35% of your net earnings from self-employment, according to Internal Revenue Service. You do not apply the tax rates to the full net earnings figure. Instead, you apply them to this reduced amount.

Write the client's net earnings on a note and mark whether they are at least $400 before you compute the tax. This keeps the threshold check separate from the rate calculation. If the earnings are $400 or more, proceed to the 92.35 percent calculation. These two figures define the start of the self-employment tax check for the return.

Before you compute the tax, confirm the client’s liability trigger and the rate components from the Internal Revenue Service. The IRS states that a person usually must pay self-employment tax if their net earnings from self-employment, excluding church employee income, were $400 or more, according to Internal Revenue Service.

The IRS explains that the rate consists of two parts: 12.4% for social security (old-age, survivors, and disability insurance) and 2.9% for Medicare (hospital insurance), according to Internal Revenue Service. These two percentages represent the combined burden for the social security and Medicare portions of the tax. You should record both percentages in your workpaper to ensure the calculation reflects the full rate structure described by the agency.

A second IRS source confirms these same rate components. The IRS states that this rate consists of 12.4% for Social Security and 2.9% for Medicare taxes, according to Internal Revenue Service. When you review the client’s return, verify that the software or manual calculation uses these specific percentages for the respective tax components. Read signature rules before you e-file while you review the return.

The $400 figure and the 12.4% and 2.9% rates are the primary IRS statements you need for this step. Keep these two sets of facts separate in your notes: one is a threshold for liability, and the other is the rate for calculation. Do not mix the $400 threshold with the rate percentages in a single calculation step.

The calculation for self-employment tax begins with a specific reduction of net earnings. When you compute the tax for a client, you apply this 92.35% factor to their net earnings before applying the specific rate components. This step is distinct from the threshold check for whether liability exists at all.

The social security component of the tax is subject to a wage-base limit. According to Internal Revenue Service, for 2024, the first $168,600 of your combined wages, tips, and net earnings is subject to any combination of the social security part of self-employment tax, social security tax, or railroad retirement (tier 1) tax. This limit applies to the combined total of all these income types. If a client has wages from employment in addition to self-employment income, you must aggregate them to determine if the $168,600 cap is reached.

If the client’s wages and tips already meet or exceed this limit, the social security part of the self-employment tax may not apply. According to Internal Revenue Service, if your wages and tips are subject to social security tax or railroad retirement tier 1 tax, and total at least $168,600, do not pay the 12.4% social security part of the SE tax on any of your net earnings. You must verify the client’s total wages and tips against this $168,600 figure before applying the 12.4% rate to their self-employment net earnings.

The Medicare component does not have this same wage-base limitation. According to Internal Revenue Service, however, all of your wages and tips are subject to the 2.9% Medicare part of the SE tax on all your net earnings. When preparing the return, you calculate the social security portion only on the amount up to the limit, but the Medicare portion applies to the entire net earnings figure after the 92.35% adjustment.

The Internal Revenue Code sets the specific percentages for self-employment income. According to Government Publishing Office, in addition to other taxes, there shall be imposed for each taxable year, on the self-employment income of every individual, a tax equal to 12.4 percent of the amount of the self-employment income for such taxable year. The same source states that in addition to the tax imposed by the preceding subsection, there shall be imposed for each taxable year, on the self-employment income of every individual, a tax equal to 2.9 percent of the amount of the self-employment income for such taxable year. These two statutory sentences define the social security and Medicare portions of the tax on self-employment income.

Business structure affects who pays these taxes. According to U.S. Small Business Administration, however, members of an LLC are considered self-employed and must pay self-employment tax contributions towards Medicare and Social Security. The agency also notes that profits are passed through to personal tax returns, and the general partner — the partner without limited liability — must also pay self-employment taxes. When a client operates as an LLC member or a general partner, you must verify that their self-employment income is included in the calculation.

Liability can persist even with other income sources. According to Internal Revenue Service, you can be liable for paying self-employment tax even if you currently receive Social Security benefits. Check the client’s status for Social Security benefits alongside their self-employment income to ensure the liability is correctly identified.

When you prepare the return, confirm that the 12.4 percent and 2.9 percent rates are applied to the correct base of self-employment income. If the client is an LLC member or general partner, include their share of profits in the self-employment income calculation.

The following table summarizes the specific facts provided by each publisher regarding self-employment tax. Each row cites the publisher and the exact context from which the fact is drawn.

This table provides a direct comparison of the rates and definitions as stated by the four distinct sources. The Internal Revenue Service provides the operational rates and the 2024 wage base limit. The Government Publishing Office provides the statutory language for the 12.4 percent tax. The U.S. Small Business Administration clarifies the liability for LLC members. The Bureau of the Fiscal Service describes the payment system. Use this table to verify that your client file matches the specific language of the source you are citing in your workpapers.

Use this blank worksheet to record the client's net earnings from self-employment and determine if they meet the threshold before you compute the tax. A blank note follows with columns for net earnings, the $400 check, the 92.35 percent amount, and notes.

Write the client's total net earnings under Net earnings. In the second column, mark whether that amount is at least $400. The third column is for the amount subject to tax, which is generally 92.35 percent of net earnings. Use the final column for any relevant details or references. If you need to contact the payment system provider, you can contact EFTPS Customer Service, available 24/7, according to Bureau of the Fiscal Service. This note helps you track the specific figures for this client's return. Attach the note to the client intake checklist.

Suppose the note shows net earnings of 400. Mark the threshold as met, because the amount is 400. Leave the reduced base and the rate parts blank on this sample, since this sample only shows the order of the check. The figure 400 is the threshold test, not the tax you enter as due.

Write the client’s business structure on your workpaper. Note whether they are an LLC member or a general partner. Mark whether they receive Social Security benefits. Keep these notes attached to the return file for review. If a prior version of the note exists, run prior workpaper checks.
