Key points from the video

  • Brian lists six drawbacks of an S corp: possibly lower Social Security benefits, the cost of a separate tax return, possible state tax at the corporate level, payroll software costs, state and federal unemployment taxes, and your time.
  • Most S corp savings come from paying less Social Security tax. Because benefits are based on your highest 35 years of covered earnings, paying in less can mean lower benefits in retirement.
  • An S corp files its own return (Form 1120-S). Brian estimates $100 to $200 for software or about $500 to $2,000 for an accountant.
  • Payroll software runs about $25 to $50 a month, and state unemployment tax on yourself about $200 to $500 a year at first (his 2019 estimates).
  • His rule of thumb: S corp savings of $10,000 to $15,000 a year are clearly worth it; $2,000 to $3,000 are not; $4,000 to $8,000 is a judgment call.

Summarized from Brian's own words in the video.

What's changed since this video

Video published November 20, 2019. Checked against current sources on October 13, 2026. These updates are from the ClearValue Lending Team, not Brian.

  • Social Security wage base Changed

    In the video: In 2020, up to $137,700 of earnings is subject to Social Security tax.

    Now: For 2026 the wage base is $184,500. The Social Security rate is still 6.2% each for employee and employer.

  • The "Chicago" corporate tax For comparison

    In the video: In Chicago, an S corp pays an additional 1.5% corporate tax.

    Now: This is Illinois's statewide personal property replacement tax: S corporations (and partnerships) pay 1.5% on their net Illinois income. It is a state tax, not a Chicago one.

  • QBI deduction (did not exist when most S corp advice was written) New since the video

    In the video: Not covered (the video predates most QBI planning).

    Now: Owners of pass-through businesses can deduct up to 20% of qualified business income. Wages you pay yourself as an employee are not QBI, so a higher S corp salary can shrink this deduction. The IRS describes the deduction continuing for tax years after 2025, with a new minimum deduction.

  • Costs Brian quotes For comparison

    In the video: Return prep $100–$200 (software) or $500–$2,000 (accountant); payroll $25–$50 a month; state unemployment $200–$500 a year.

    Now: These are Brian's 2019 estimates. We have not re-checked current market prices; state unemployment rates are set by each state.

The real costs of an S corp: a plain-English guide

ClearValue Lending Team· Scored against ClearValue's published methodology·Updated

Most S corp content sells the tax savings. Brian's video does the opposite: it lists what an S corp costs you, so you can decide whether the savings are worth it. This guide follows his six drawbacks in order, updates the figures, and adds one cost he did not cover. Federal figures come from irs.gov; state examples come from the Illinois and California tax agencies. All were checked on October 13, 2026.

Brian's six drawbacks at a glance

Brian covers this in the video · watch from 0:00

An S corp is a tax election, made on Form 2553, by a corporation or an LLC that elects to be taxed as one. The main benefit is paying yourself part salary and part distributions. Brian lists six costs on the other side.

Drawback 1: lower Social Security benefits

Brian covers this in the video · watch from 1:20

Brian calls this the one most people miss. Social Security tax applies to wages and self-employment earnings up to a yearly limit, the wage base. Your retirement benefit is calculated from your highest years of covered earnings. Brian says 35 years; under the Social Security Act the count is your elapsed working years minus five, which is 35 for most retirees.

Here is the catch. As a sole proprietor, you pay self-employment tax on almost all of your profit. As an S corp owner, you pay Social Security tax only on your salary. Distributions escape it. That is where most of the savings come from. But less Social Security tax paid in can mean lower recorded earnings, and a lower benefit later.

It matters most if your salary would otherwise be well below the wage base, and less if you will have 35 strong earning years anyway. It is a trade-off to weigh, not a reason on its own to skip an S corp.

Social Security wage base: then and now
YearWages subject to Social Security taxRate (each side)
2020 (in the video)Up to $137,7006.2%
2026Up to $184,5006.2%
Social Security wage base: then and now. 2026 figure from IRS — Topic 751, Social Security and Medicare withholding rates. Medicare tax (1.45% each side) has no wage limit.

Where the savings come from: a worked example

To weigh the drawbacks, you need a rough size for the savings. Here is a simple illustration using IRS rates. It ignores income tax effects, which also change.

  1. As a sole proprietor with $100,000 of profit, self-employment tax applies to 92.35% of it at 15.3%. That is about $14,130.
  2. As an S corp paying a $60,000 salary, Social Security and Medicare apply to the salary only: 7.65% from you and 7.65% from the corporation, about $9,180 in total.
  3. The difference is about $4,950 a year, before the costs below.

The salary has to be reasonable for the work you do. The IRS can reclassify distributions as wages if it is not, so you cannot simply set a tiny salary to save more.

Drawback 2: a separate tax return

Brian covers this in the video · watch from 4:41

As a sole proprietor, your business goes on a schedule in your personal return. An S corp is a separate entity and files its own return, Form 1120-S. Its income then flows to your personal return through a Schedule K-1.

Brian's 2019 estimate: about $100 to $200 for do-it-yourself software, or roughly $500 to $2,000 for an accountant, depending on where you live. We have not re-checked current prices.

Drawback 3: state tax at the business level

Brian covers this in the video · watch from 5:53

Brian's example is a 1.5% tax on S corps in Chicago. The tax is actually statewide: Illinois charges S corporations a 1.5% personal property replacement tax on net Illinois income. A sole proprietor does not pay it.

California is another example. It taxes S corporations 1.5% of California income and charges a minimum franchise tax of $800 a year, even in a year with a loss (the minimum is waived for the first year).

Most states do not tax S corps this way, but several do. Check your state's revenue agency before you elect.

Two state examples

Illinois1.5% replacement tax on net Illinois incomePartnerships pay it too
California1.5% of California income; $800 minimum franchise taxMinimum waived for the first year
Two state examples. Sources: Illinois Department of Revenue — What are the income and replacement tax rates?; California Franchise Tax Board — S corporations. Checked October 13, 2026.

Drawback 4: payroll costs

Brian covers this in the video · watch from 7:02

The S corp saving depends on splitting your income into salary and distributions. Salary means payroll. Brian recommends software that handles the quarterly reports, tax deposits and W-2s, and puts the cost at about $25 to $50 a month (his 2019 estimate).

The duties themselves are real: federal tax deposits must be made electronically, Form 941 is due every quarter (or Form 944 yearly for the smallest employers), Form 940 yearly, and W-2s by January 31. See Brian's payroll setup video for the details.

Drawback 5: unemployment taxes on yourself

Brian covers this in the video · watch from 8:11

As an employee of your own S corp, in most states the corporation pays state unemployment tax on your wages. Brian estimates $200 to $500 a year at first. He says many states lower the rate, sometimes to $30 to $50 a year, after about three years without layoffs. Each state sets its own rates, so treat these as his estimates.

There is also federal unemployment tax (FUTA): 6.0% on the first $7,000 of wages, cut to 0.6% if you pay your state unemployment tax in full and on time. That is up to $42 a year per employee.

A cost Brian did not cover: a smaller QBI deduction

Since 2018, owners of pass-through businesses can deduct up to 20% of qualified business income (QBI). Income you earn as an employee is not QBI. So in an S corp, the salary you pay yourself is not eligible, only the profit left after it.

That means a higher salary lowers your Social Security tax savings and your QBI deduction at the same time. The two have to be planned together. The IRS describes the deduction continuing for tax years after 2025, with a new minimum deduction for active businesses.

Drawback 6, your time, and Brian's rule of thumb

Brian covers this in the video · watch from 9:35

The last drawback is time: running payroll, talking to your accountant, keeping the filings straight. None of it exists as a sole proprietor.

Brian's bottom line is to compare the tax savings with all these costs. His personal rule of thumb:

Brian's rule of thumb on yearly S corp tax savings
Yearly tax savingsBrian's view
$10,000 to $15,000Clearly worth it
$4,000 to $8,000A judgment call; weigh your own costs and time
$2,000 to $3,000Not worth it to him; the net benefit may be a few hundred dollars
Brian's rule of thumb on yearly S corp tax savings. His opinion from the video, not a rule. Your costs depend on your state, your accountant and your salary.

A simple way to use it: estimate the savings (as in the worked example above), subtract the return prep, payroll, state taxes and unemployment taxes, and ask whether what is left is worth your time and a possibly smaller Social Security benefit.

Next steps

Educational information, not tax or legal advice. ClearValue Lending is an education and comparison platform; it does not prepare tax returns or give tax advice. Whether an S corp makes sense depends on your numbers and your state; talk to a CPA or enrolled agent.

Questions viewers ask

Does an S corp reduce my Social Security benefits?

It can. You pay Social Security tax only on your salary, not on distributions, so less earnings may be credited to your record. Benefits are based on your highest earning years, so the effect depends on your salary and your other working years.

What is the Social Security wage base for 2026?

$184,500. Social Security tax of 6.2% each from employee and employer applies up to that amount. In the 2019 video, Brian quotes the 2020 base of $137,700.

Does an S corp file its own tax return?

Yes. It files Form 1120-S, and each owner gets a Schedule K-1 to report their share on their personal return. Brian estimates $100 to $200 for software or $500 to $2,000 for an accountant (2019 figures).

Do states tax S corporations?

Some do. Illinois charges a 1.5% replacement tax on net Illinois income, and California charges 1.5% plus an $800 minimum franchise tax. Many states do not tax S corps at the entity level; check yours.

Do I pay unemployment tax on myself in an S corp?

Usually, yes. The corporation pays state unemployment tax on your wages in most states, and federal unemployment tax of 6.0% on the first $7,000, cut to 0.6% with the full state credit.

How does an S corp affect the QBI deduction?

Your salary is not qualified business income, so paying yourself more reduces the 20% QBI deduction. Salary, payroll tax savings and QBI need to be planned together.

How much do I need to save for an S corp to be worth it?

Brian's rule of thumb: $10,000 to $15,000 a year is clearly worth it, $2,000 to $3,000 is not, and $4,000 to $8,000 is a judgment call. Subtract your actual costs to decide.

Can I pay myself a very low salary to save more?

No. The IRS requires reasonable compensation for the work you do before non-wage distributions, and it can reclassify distributions as wages subject to employment taxes.

What are the main costs of running an S corp?

A separate tax return, payroll software, state and federal unemployment taxes, any state entity-level tax, and your time. Brian's 2019 estimates put the yearly total in the high hundreds to a few thousand dollars.

Introduction to disadvantages watch from 0:00

Welcome back to our channel, ClearValue Tax. My name is Brian Kim, I'm a certified public accountant, and in today's video we will be discussing the drawbacks of an S corporation. So we're talking about the S Corp disadvantages. I'm sure you can find a whole slew of videos out there talking about the greatness and the benefits of the S Corp, just saying it's the greatest thing. However, that depends on your situation. So we're gonna be providing you the drawbacks of the S Corp so you can have all the information at hand to make the best decision on whether it's right for you. So I'm gonna list them out here first, and then we're gonna go into details about each one.

So here's the list of the drawbacks. So you will have potentially reduced Social Security benefits upon retirements. There's the additional cost of the tax return of the S corp. There's a chance, depending on [where] you are operating out of, that you will be subject to state income taxes at the corporate level, which you wouldn't have paid as a sole proprietor. There's the payroll software costs. There's a unemployment taxes at the state level, and also the FUTA, the federal unemployment taxes as well. And just the cost of your time, just you going through all these additional compliance motions. Okay, so let's dive into the Social

Reduced social security watch from 1:20

Security benefits. So let me show you how this works. So do you even know how is the Social Security benefits are calculated? So this is what happens. Each year there's a certain amount of your income that's subject to Social Security taxes. We're talking about if you're self-employed, even if you're an employee getting a W-2, there's a certain amount of income that's subject to Social Security taxes, currently at a rate of 6.2%. Okay, so there's a maximum of the amount that is subject to Social Security taxes per year. There's an annual maximum, they call that the wage base ceiling. So in 2020, up to a hundred thirty seven thousand seven hundred is subject to Social Security taxes.

Okay, so if you make over that amount, you're no longer going to be subject to Social Security taxes on your income. So a lot of you who are making over that amounts during the year, you might notice that you get a big net pay bump and don't know why. That's because that means you've made over that amount in that year, and you're no longer being charged at six point two percent, therefore your net paychecks bigger. That's because at a certain point, which is adjusted for inflation each year, you stop paying Social Security taxes because you've paid in the maximum amounts for that year. Okay, so the way it works, how you calculate your Social Security benefits, it's based off your highest 35 years, your highest 35 years of income.

There's a calculation that's being run, but to just give you a high-level overview, they look at your highest grossing 35 years, and based off how much you've paid into the system, your how much Social Security taxes you've paid, that's how your benefits are calculated. So with the S corporation, perhaps you know, perhaps you don't, where's the bulk of the savings coming from in comparison to operating as a sole proprietor? You are saving the bulk of your money operating as an S corporation by paying less Social Security taxes. So how is that gonna affect you? If you're paying less Social Security taxes into the system, remember, that's how they're calculating your benefits, your Social Security benefits upon retirement.

They're looking how much you pay into the system for the past 35 years, the highest or at 35 years, and if you're paying less into the system with Social Security taxes, well, your benefits will be reduced then. So if you did not know this, I hope you learned something. If you have, please give me a thumbs up or like, that highly appreciate that, that helped our channel. And okay, I hope that's a revelation to you if you didn't know that, because the bulk of the savings is coming from paying less Social Security taxes. How is that gonna affect you? That affects you negatively, the Social Security benefits [upon] retirement. Okay, so moving on to the next one. As an S corporation,

Tax filing requirements watch from 4:41

you are filing a separate tax return, a separate 1120-S S corporation income tax return. So the way you are filing before, as a sole proprietor, you were filing just on an additional schedule on your individual income tax return. So you're filing your business activity on your personal income tax return as a sole proprietor. That's no longer the case with an S corporation. With an S corporation, it's a legally separate entity that needs its own tax returns. So you're going to be filing a separate corporate tax return. So however you're going to be doing this, if you're gonna buy at home software to do this, I mean, that's still gonna run you probably about a hundred to two hundred dollars for the software costs.

Or if you're gonna work with an accountant, you might be paying five hundred [to] two thousand dollars for this corporate tax return, depending on where you live and accountants, whatever they're charging. It might be less, it might be more, but that's typically on average what they will be charging for this S corporation tax return. So while we're talking about

Additional state taxes watch from 5:53

the tax returns, you know, one additional cost that might be applicable to you, depending on where you live. I'll give you an example. So if you're in Chicago, your corporation, your S corporation will pay an additional corporate tax at a rate of 1.5%. It's not the biggest, but that's still an additional 1.5 percent corporate tax at the business level. This is something that you as a sole proprietor would not be subject to, because you were not operating as a corporation. But as an S corporation, in certain states you will be subject to an additional [entity]-level tax. So you need to take that into consideration. As an S corp, again, a lot, the pretty much the bulk, or all, the tax savings is coming from the reduction of Social Security Medicare taxes, which is self-employment taxes to the sole proprietor. But anyways, it's about income

Payroll software costs watch from 7:02

classification. Please check out our other videos going more in depth at in detail about that. But you're doing that with the manipulation of income classification, with salary on payroll versus your business income, your dividend distributions. So with that, you need a salary. With that, you need a payroll system. We have a whole separate video about the payroll, the payroll set up and all that too. But with the payroll system, expect a monthly software cost of whatever payroll provider you're choosing. Expect the monthly software costs about $25 a month to $50 a month. You know, the, again, in the other videos we'll discuss the beauty, but to recap, you know, they keep, they take care of all the filing requirements, the quarterly reports, the tax deposits, that W-2 creation, all of that.

So I mean, it's worth it. However, you're still gonna be forking over twenty-five to fifty dollars a month for the payroll software costs. So that's an additional cost that you would not have as a sole proprietor. Another

Unemployment taxes watch from 8:11

thing is that this is based on your state as well. With an S corporation, you will be an employee of your S corporation, you will be an employee shareholder. So if you are illegal, if you are a legal employee of your business, in most states you'll need to pay state unemployment taxes on yourself. Your business will need to pay state unemployment taxes on you as the employee. So this is going to range from state to state, per person, per firm, per employee, but generally you're talking about state unemployment tax is about 200 to 500 dollars a year. However, depending on the states, a lot of states, that cost drops down to as low as $30 a year or $50 a year per employee, per person, if you have a good record of not laying your employees off.

So it's long as you don't lay yourself off. But usually you need to build a track record of about three years for that unemployment cost to be reduced. So from your year one and subsequent years, until you reach that point, expect to pay state unemployment taxes, which is an employer tax on yourself, for about two hundred to five hundred dollars annually. Okay, and okay, I mean, those are the major costs,

Compliance and final advice watch from 9:35

but then going through all this compliance work, you know, we're talking about, okay, even if you have [an accountant] doing your tax return, well, you still need to do the communication with the accountant. You need to go through all those motions. And even running the payroll, you know, if you're gonna be doing payroll yourself, you know, you're gonna be running through those motions, and that's gonna be eating up your time. These are things that you wouldn't have to have done if you are not an S corporation. So you need to take all these things into consideration and weighing the pros and cons to decide whether it's worth it to be an S corporation.

Now listen, in this video I'm talking about only the negative things. So this is like a Debbie Downer video, this is she's talking about the negatives. You know, there are so many advantages and benefits to being an S corporation, you can see our other videos, but you need to weigh both sides of it. But ultimately, what is it boiling down to? It's how much taxes are you going to save as operating as an S corporation, and what are the costs. So if you're going to be saving $10,000, $15,000 operating as an S corporation, then I would say yes, you know, these costs of the S corp, these disadvantages of the S corp, you know, it's gonna be totally worth it.

The benefits will outweigh the costs. However, in a situation where your tax savings what the S corp will be about, you know, this is just my opinion, if your savings will be about two thousand dollars, you know, three thousand dollars, it won't be worth it, at least not to me, not money, not from my point of view, because you have all these additional costs that you wouldn't be paying if you weren't operating as an S corp, and the additional time. You know, what's the net dollar benefit? You know, it's going to be a thousand dollars, or maybe even a few hundred dollars. You know, in that situation, it just wouldn't be worth it to me.

You know, if your tax savings is in the realm of four thousand, seven thousand, eight thousand, that, you know, that's kind of a middle ground. You know, that's that's kind of an area where it's not clear-cut, where it's clear-cut [unclear] clear-cut don't be an S corp. In that situation, you need to just, you know, it's your purpose personal preference, you know, to weigh the pros and cons and see whether it's worth it to you. Okay, so I hope that this video has been helpful, because a lot of times people are not going to be talking about the disadvantages of an S corp. If you have any questions or comments, please leave them below, I'd be happy to get back to you. And again, if you found this video helpful, please give me a thumbs up, I'd highly appreciate that, and though it helped the channel a lot. Thanks so much, until next time, take care.
