The Real Cost of an S Corp (And When the Savings Are Worth It)

The S Corp election gets pitched as a tax-savings move. What doesn’t get pitched: what it costs to keep one running correctly.

The IRS doesn’t set an income minimum for S Corp eligibility, and every business’s numbers are different, so there’s no single dollar figure that makes the call for you. What tends to hold true: the election generally makes sense once you’re building a business you plan to stay in, and once your savings potential is big enough to outweigh the added cost of running it right.

Savings are usually what brings solopreneurs to this conversation, though the shift to formal payroll and bookkeeping can pay off in other ways too, like more structured retirement contributions or just running a tighter, more disciplined business. That’s a separate conversation, but worth keeping in view.

An S Corp isn’t free to maintain. Here’s what you’d actually be paying for.

The Real Costs of S Corp Compliance

Electing S Corp status doesn’t just change how your income is taxed. It also changes what your business has to do administratively. Here’s where the cost of an S Corp actually shows up.

Payroll and Reasonable Salary

Unlike a sole proprietorship or an SMLLC, an S Corp owner can’t just pay themselves from the business account. The IRS requires a reasonable salary, paid through payroll, with a W-2 issued at year end. That means an ongoing payroll subscription, plus the work of running it correctly and on schedule. Reasonable salary itself is a judgment call, not a fixed number, and getting it wrong in either direction carries its own risk.

If you’re comparing providers, our comparison guide to payroll solutions for solopreneurs breaks down what to look for and how the major options stack up.

A New Business Tax Return

An S Corp comes with a filing that doesn’t exist for a sole proprietor or SMLLC: a separate business tax return, due earlier in the year than your personal return. It calls for more detailed accounting than most solopreneurs are used to tracking. Self-prep options exist, but it’s a whole different set of forms to learn. Hiring it out is common, and costs vary by complexity and location, but can run somewhere between $750 and $3,000.

Formal Bookkeeping

A spreadsheet may have worked when you were a sole proprietor. An S Corp needs real books, kept current, with business and personal finances fully separated. This isn’t a rule you can get away with skipping. It’s what an S Corp actually needs to function, since your tax return, your payroll, and your reasonable salary determination all depend on accurate numbers.

State and Local Filing Fees

Your LLC is the legal foundation underneath everything else, and it comes with its own annual fee assessed by the state just to stay in good standing. That fee exists whether you elect S Corp status or not, it’s the cost of maintaining the LLC itself.

Once you layer an S Corp election on top of that LLC, some states also require a separate state-level tax return for the S Corp, with its own tax assessed on the business’s income. This is a second, distinct cost, not a replacement for the LLC maintenance fee. Most states impose something in this category. For most businesses it isn’t a material factor in the S Corp decision on its own, but it recurs every year and is worth accounting for.

The bigger flag is when a business operates somewhere with a local layer of tax on top of federal and state, most commonly at the city level. New York City is the clearest example: its General Corporation Tax (GCT) assesses its own tax on S Corp income, at a rate close to 9%, on top of what’s owed federally and to the state. If you do business in a jurisdiction with an added local tax like this, consider it in the math from the start.

One-Time LLC Formation Cost

The one-time cost here belongs to forming the LLC, the legal entity the S Corp election attaches to. The S Corp election itself is filed directly with the IRS on Form 2553, and there’s no fee to submit it. So the one-time cost to budget for is LLC formation with your state, not the S Corp election itself.

When S Corp Savings Outweigh the Cost

The election tends to pencil out when two things are true at the same time:

• You’re building something ongoing, not closing out a single project or short-term contract.
• Your profit is consistent enough that the potential payroll tax savings could reasonably exceed what it costs to run the entity correctly.

Businesses that are newer, less predictable in income, or still testing whether the work is sustainable often haven’t reached the point where the savings potential clears that bar. Businesses with steady, established profit often have. Where your specific number lands depends on your income, your state, and how you plan to pay yourself, which is exactly why this is worth running with real numbers rather than a rule of thumb.

Worth remembering: this bar isn’t only financial. Electing S Corp status also means taking on a new annual filing requirement, payroll and a separate business tax return, for as long as the election stays in place. Running that on schedule takes real time, whether you’re doing it yourself or overseeing someone who is, so it’s worth weighing alongside the dollar figures.

Piecing It Together vs. One Membership

Assembling these pieces yourself means coordinating separate vendors, each with its own deadlines and logins, on top of the cost of each one. Collective bundles payroll, bookkeeping, formation, and business and individual tax filings into one membership built specifically for solopreneurs. For S Corp Members, payroll and formation are included as part of that membership rather than billed as separate add-ons. Whether the total cost lands below assembling the same services individually depends on what you’d otherwise be comparing it to, but it’s worth pricing out both paths before deciding.

The savings are usually the reason this conversation starts, but a well-run S Corp, payroll and books included, tends to leave you with a more organized business either way.
