This post will cover **changing from S corp to C corp** for business owners who feel boxed in by their current tax structure and want to know if flipping the switch will actually lower taxes or just create a new set of problems. Too many owners assume once they pick S status, they are stuck for life or that C status is only for giant public companies. Neither is true, but the consequences of switching can be expensive if you guess your way through it.

Quick Answer

Changing from S treatment to C treatment is possible, but it is not a casual move. For federal purposes, you revoke your S election and the corporation continues as a C corporation. That means corporate level tax on profits, double tax exposure on distributions, different rules for retained earnings, and potential traps around appreciated assets and built in gains the IRS watches closely. In California, you also need to account for state corporate income tax plus the minimum franchise tax. The move can make sense once profits are high enough and you plan to reinvest aggressively, but it needs to be modeled carefully year by year.

Why some owners consider changing from S corp to C corp

Most closely held corporations start life as pass through entities because the idea of a single layer of tax is attractive. Profits pass to the shareholders, show up on their 1040 through Schedule K 1, and there is no corporate level tax if the S rules are respected. That works well while owners are pulling out most of the cash each year.

As the business scales, three pressure points show up:

• Owners hit higher individual tax brackets, often 32 percent or above at the federal level.
• The qualified business income deduction phases out or becomes less reliable.
• The company wants to retain more profit inside the entity for growth, acquisitions, or major hiring.

At that point, some owners look at the flat C corporation federal rate and wonder if a switch would cut the overall bill. For example, a company with $800,000 of annual profit that plans to reinvest $650,000 for the next five years may find the corporate rate appealing compared to flowing the full amount to shareholders taxed at high marginal rates each year.

If you are in this situation and operate an active trade or business, it may be time to talk with experienced business owner tax advisors who understand long range entity planning rather than just annual filing.

Core tax changes when you move from S status to C status

When an S election is in place, the corporation itself generally does not pay federal income tax. Instead, income, deductions, credits, and certain separately stated items pass through to the shareholders under Subchapter S rules. Once the S election ends, the same legal entity becomes a regular corporation under Subchapter C. That shift changes how the IRS and California Franchise Tax Board treat every dollar of profit and distribution from that date forward.

Corporate level income tax

After revocation takes effect, the corporation begins paying corporate income tax on its taxable income each year. At the federal level, that means applying the flat corporate rate to profits. In California, the corporation pays state corporate tax and at least the minimum franchise tax each year regardless of profit level.

For a profitable business that plans to leave substantial cash inside the entity, this can reduce the immediate tax burden on owners compared with passing everything through and paying at individual rates. For an owner who expects to distribute most of the cash out each year, however, it can increase the total tax burden once you add shareholder level tax on dividends.

Double taxation of shareholder distributions

S shareholders are used to taking distributions that are not taxed again when paid out, as long as basis and accumulated adjustments allow it. Under C rules, once the corporation has earnings and profits, distributions are treated as dividends to the extent of those earnings. That means taxable income to the shareholders on their personal returns, often at qualified dividend rates, and no deduction for the corporation.

This double layer is the central tradeoff in any decision to leave S status. If you expect to keep profits parked in the company for future projects or reserves, the second layer of tax may be small or delayed. If you expect to pull profits out regularly as cash, the second tax on dividends can quickly erase the benefit of the corporate rate.

Retained earnings and accumulated adjustments

Under S rules, the accumulated adjustments account tracks previously taxed income that can generally be distributed tax free to shareholders. When S status ends, that account freezes and future activity is tracked through earnings and profits under C rules. That means distributions after the switch must be carefully classified so you do not accidentally turn what should be a return of previously taxed S income into a taxable dividend.

According to IRS Publication 542, corporations must understand how to track earnings and profits if they want to avoid mischaracterizing shareholder distributions. This is one of the reasons owners often bring in outside professionals for the first year after a status change.

Because the accounting and compliance work gets more involved at this level, many owners choose to delegate the day to day tracking to a dedicated bookkeeping and payroll team so strategy does not get lost in spreadsheets.

How the IRS treats the actual switch

For federal purposes, ending S status usually happens in one of two ways. Either the shareholders file a statement revoking the election, or something happens that automatically terminates the election, such as a disqualified shareholder coming in or a second class of stock being created. Voluntary revocation is the path you choose when you want to become a C corporation on purpose.

Revocation mechanics and timing

To revoke on purpose, shareholders who collectively hold more than 50 percent of the shares sign a statement that includes the name, address, and taxpayer identification number of the corporation, a declaration that the S election is revoked, and the effective date they want. This is filed with the same service center where the S election was originally sent. If the effective date is not specified, the revocation is effective on the first day of the tax year in which it is filed, subject to certain timing rules.

Many owners aim for a switch effective on the first day of a new tax year so they do not have to deal with a short S year and a short C year filing in the same calendar period. That means planning the decision months in advance. Once the revocation is in place, the general rule is that you cannot reelect S status for a period of years unless you obtain IRS consent, so treat the decision as a multi year move, not a quick experiment.

Built in gains and appreciated assets

If your S corporation used to be a C corporation in the past, you may already be familiar with the built in gains tax rules under Internal Revenue Code section 1374, which impose a corporate level tax on certain gains recognized during a recognition period after converting from C to S. When going the other direction, from S to C, you do not pick up a new built in gains exposure, but you absolutely need to consider what appreciation exists inside the entity on the day of the switch.

The reason is simple. Under S treatment, appreciation often ends up taxed to the shareholders when a sale occurs, potentially at long term capital gain rates. Under C treatment, a corporate sale of appreciated assets can trigger corporate level tax followed by shareholder level tax when proceeds are distributed. If there is a chance you will sell major assets or the entire business in the next few years, you need to model those scenarios under both structures before signing any revocation document.

KDA Case Study: Scaling California contractor considers life after S status

A California construction company operated for years as an S corporation owned by two siblings. In 2023, their net profit after officer wages was about $900,000, and they expected similar or higher numbers going forward. Both owners were already in high individual brackets. They were reinvesting heavily in equipment and building a cash reserve for a future acquisition.

They came to KDA asking whether changing to C status would cut their tax bill or backfire. Our team gathered five years of returns, balance sheets, and projections. We modeled two paths over a five year horizon. In the first scenario, the company stayed S, passed through profits each year, and the owners pulled out roughly $700,000 annually. In the second scenario, the company revoked S status, paid corporate level tax on profits, limited dividends to $200,000 per year, and left the rest inside the corporation.

Under the S scenario, combined federal and California tax on pass through income for both owners averaged about $310,000 per year. Under the C scenario, corporate tax plus shareholder dividend tax totaled about $255,000 annually, assuming reinvestment of the majority of profits. Over five years, the C structure saved roughly $275,000 compared to staying S, largely because less income showed up on the owners personal returns during those years.

The key was discipline. We built written policies on dividend levels, retained earnings targets, and exit planning. Without that structure, they would have been tempted to drain more cash, and the double tax cost would have eaten into the savings. With the plan in place, the switch made economic sense for their growth goals.

Red flag alert: Common mistakes when leaving S status

There are several patterns that repeatedly cause trouble when a closely held corporation moves out of S status. These are not theoretical risks. They are issues that surface in examinations and in shareholder disputes when expectations are not aligned.

Ignoring the impact on shareholder cash flow

Owners who are used to steady S distributions sometimes forget that, under C rules, every dollar they take out once earnings and profits exist can carry an additional tax bill. If the company continues to distribute the same level of cash after the switch without planning, the owners may discover that their personal tax liability has gone up rather than down.

This is why the decision to switch should be paired with a written distribution policy. For example, you might cap after tax dividends at a percentage of prior year net income and set clear rules for when additional cash can be taken as bonuses or other compensation. Without those guardrails, the theoretical tax savings of the corporate rate rarely hold up.

Failing to track basis and former S earnings correctly

Another trap comes from sloppy record keeping around shareholder basis and the accumulated adjustments account. Once S status ends, those S era items do not disappear. They still matter for determining which part of future distributions can come out tax free as previously taxed S income versus which part is treated as taxable dividends from C era earnings.

Publication 542 and other IRS guidance explain how distributions are ordered between accumulated adjustments, earnings and profits, and basis. In practice, however, many small corporations do not have clean historical records, which makes correct classification difficult. Cleaning that up before a status change is often less painful than trying to reconstruct it under pressure later.

Will changing from S corp to C corp lower my total tax bill

Whether **changing from S corp to C corp** actually saves money depends on your profit level, distribution habits, exit plans, and state taxes. There is no single answer, but there are clear patterns that point toward or away from a switch.

Situations where a C structure can help

• High profits with low planned distributions. If your corporation earns $600,000 to $1,200,000 per year and you expect to leave most of it inside the entity to fund growth, paying corporate tax on those profits can reduce current year tax compared to passing them through at high individual rates.
• Long term reinvestment horizon. If there is no plan to sell the business or its core assets in the next decade, and you are building a balance sheet for future expansion, the second layer of tax may be far in the future, making the present value of the savings attractive.
• Compensation planning flexibility. C corporations can design different mixes of salary, bonus, and benefits for owner employees within reasonable compensation rules, which gives planning room that some S shareholders do not fully explore.

Situations where staying S is often better

• Regular full profit distributions. If you consistently distribute most profits to shareholders each year, the double tax on dividends can push the overall burden higher under C rules compared to staying S.
• Near term sale of assets or equity. If you expect to sell the operating company or major appreciated assets within a few years, S status often provides better after tax results on a sale, particularly for asset deals.
• Moderate income owners. Shareholders who are not in the top federal brackets may not see enough rate arbitrage between their personal bracket and the corporate rate to justify the additional complexity and risk.

In many cases, a blended approach that uses additional tools, like separate entities or holding companies, can capture some benefits without a full status change. That is where targeted tax planning services for business owners have an advantage over pure compliance work.

How California layers on additional considerations

California adds its own twist to the decision. S corporations in California pay a reduced rate on net income plus the minimum franchise tax, while C corporations pay the regular corporate rate. Individual shareholders also pay California tax on their pass through income or dividends.

For a California resident owner already facing high state and federal brackets, the way California taxes corporate income and shareholder distributions can tip the scales in either direction. That is why any model you run needs to include both federal and state layers, as well as payroll taxes and potential local taxes if your city imposes them.

For business owners who want to dig into state specific impacts across different growth scenarios, using a structured calculator for corporate and owner level tax can highlight break even points and downside risk. While there is no dedicated tool just for this type of status change, you can often combine business projections with a general small business tax calculator to get a first pass view before commissioning a more detailed analysis.

What if you regret leaving S status later

Owners sometimes ask if they can treat a change from S status to C status as a trial run. The general rule is that once an S election is terminated, either voluntarily or automatically, you cannot make a new S election for a specified period of time without IRS consent, often five years. That cooling off period is meant to prevent constant toggling between pass through and corporate treatment based on short term swings in income.

If you believe your profit pattern may be volatile or your personal tax picture may change significantly in the near future, you need to weigh that lack of flexibility. In some cases, it is better to use alternative structures, such as separate entities for new lines of business, instead of changing the status of your existing operating corporation.

Owners who have already revoked S status and want to return later should be prepared to demonstrate a strong business reason for the new election and to show that the prior revocation was not part of a pattern of abusive tax motivated behavior. That conversation requires careful preparation and documentation.

Will this trigger an IRS audit

Switching from S treatment to C treatment does not, on its own, automatically trigger an examination. The IRS already deals with corporations entering and leaving S status every year. What raises red flags is when the financial pattern around the change suggests the move was purely about avoiding a specific tax liability, especially if there are large one time gains or unusual distributions around the transition.

To reduce audit risk, make sure your corporate compensation policies, dividend history, and board minutes tell a consistent story. Document the business reasons for the change, such as capital investment plans, lender requirements, or planned public offerings. Keep your filings accurate and timely, and follow the IRS instructions for revoking the election and filing the final S year return and the first C year return correctly.

Remember that the IRS has detailed guidance on corporate returns and S elections in resources like Publication 542 and the instructions to Form 1120 and Form 1120 S. Aligning your filings with those instructions is part of showing that the change is legitimate and well managed.

Bottom line

For a profitable, growing company, **changing from S corp to C corp** can be a powerful move if you expect to reinvest earnings for many years and can live with strict discipline on owner distributions. For owners who rely on steady cash from the company or who may sell in the near term, the same move can generate unnecessary double taxation and create exit problems.

The decision is not about which label sounds better. It is about matching your tax structure to your actual behavior, cash needs, and long term plans. That requires modeling several scenarios, reading the fine print in IRS rules, and understanding how California taxes both corporate income and shareholder level income.
