I'm Retired and Collecting Social Security. Do I Still Have to Pay Self-Employment Tax?

One of the most common questions we hear from self-employed retirees is:

"I'm collecting Social Security now. Do I still have to pay self-employment tax on my business income?"

The short answer is:

Yes, in most cases, you do.

Many retirees assume that once they begin receiving Social Security retirement benefits, their obligation to pay Social Security and Medicare taxes ends. Unfortunately, that's not how the tax system works.

If you're self-employed and continue operating a business, the IRS generally requires you to continue paying self-employment tax on your net business income. Let's break down what that means.

What Is Self-Employment Tax?

Self-employment tax is the self-employed equivalent of Social Security and Medicare taxes that employees see withheld from their paychecks.

When you work for an employer:

• You pay part of the Social Security and Medicare tax.

• Your employer pays the other portion.

When you're self-employed:

• You pay both portions through self-employment tax.

  
  

This applies regardless of whether you're already receiving Social Security retirement benefits.

But Haven't I Already Paid Into Social Security My Entire Life?

Probably. And that's exactly why many retirees are surprised.

The Social Security retirement benefit you're receiving is based on your work history and earnings record. Receiving those benefits does not exempt future self-employment income from Social Security and Medicare taxation.

Think of it this way:

• Your Social Security benefit is based on what you've already earned and contributed over your lifetime.

• Your self-employment tax is based on what you're earning now.

  
  

The two are connected, but they are not the same thing.

Example: Retired but Still Working

Let's say:

• You're age 68.

• You're collecting Social Security retirement benefits.

• You operate a consulting business.

• Your business earns $120,000 in net profit.

Even though you're receiving monthly Social Security benefits, your business income may still be subject to self-employment tax.

Many retirees discover this for the first time when they prepare their tax return and see a significant tax bill.

Can My Social Security Benefits Become Taxable?

Yes. This is another area that catches retirees off guard.

Many people assume Social Security benefits are completely tax-free. In reality, Social Security benefits can become partially taxable depending on your total income.

The IRS looks at a calculation known as provisional income, which generally includes:

• Business income

• Wages

• Pension income

• Interest income

• Investment income

• A portion of your Social Security benefits

As income rises, up to 85% of your Social Security benefits may become taxable.

Notice that this does not mean 85% of your benefits are lost.

It simply means that up to 85% of the benefit amount may be included in taxable income for federal income tax purposes.

Example: High-Income Retiree

Suppose a retiree receives:

• $30,000 in annual Social Security benefits

• $200,000 in net self-employment income

  
  

Because of the business income, the retiree will likely:

• Pay income tax on a portion of the Social Security benefits

• Owe self-employment tax on the business income

• Owe regular federal income tax based on overall taxable income

This surprises many business owners who assumed retirement benefits would reduce their tax burden.
