Is Your S-Corp Election Still Right for 2027? 5 Entity Structure Checks to Run This Quarter

If your business is generating more than $1 million in annual revenue, your entity structure should not be on autopilot.

An S corporation election that made perfect sense several years ago may no longer fit your current profit level, ownership plans, reinvestment strategy, or exit goals. The same is true for an LLC taxed as a partnership, a sole proprietorship, or a C corporation.

With the One Big Beautiful Bill Act making the Qualified Business Income deduction permanent, preserving 100% bonus depreciation, increasing the 2026 Section 179 limit, and leaving the federal C-corporation tax rate at 21%, this is an important quarter to review your structure before 2027 arrives.

At SJ Accounting Services LLC, we encourage business owners to treat entity planning as an ongoing strategic decision, not a form filed once and forgotten.

Here are five checks to run this quarter.

1. Compare Your Actual Tax Profile Under Each Entity Option

The first question is not, “Is an S corporation always better?”

The better question is: Which structure produces the most favorable overall tax and cash-flow result for your business, your owners, and your future plans?

An S corporation generally provides pass-through taxation. Business income passes through to shareholders, who report it on their individual returns. Qualifying owners may also benefit from the permanent 20% Qualified Business Income deduction, subject to taxable-income, wage, property, and business-type limitations.

A C corporation, by contrast, pays federal income tax at a flat 21% rate. That can be attractive for a company retaining substantial profits to fund expansion, acquire another business, or build cash reserves. However, distributions may create a second level of tax when paid as dividends to shareholders.

An LLC may be taxed as:

• A disregarded entity or sole proprietorship

• A partnership

• An S corporation

• A C corporation

The legal entity and tax election are related, but they are not the same thing. That distinction matters when you evaluate a conversion.

For 2027 planning, model at least these scenarios:

• Current S-corporation treatment

• LLC taxed as a partnership

• C-corporation taxation

• Potential changes in owner compensation and distributions

• Different levels of retained earnings and reinvestment

Your model should consider federal and state income taxes, payroll taxes, the QBI deduction, estimated payments, retirement contributions, and the tax cost of future distributions or a sale.

The permanent QBI deduction is valuable, but it does not automatically make an S corporation the best answer for every high-income business.

2. Revisit Your QBI, Wage, and Owner Compensation Strategy

For many S-c corporation owners, the QBI deduction is only one part of the equation. The relationship between owner wages and pass-through profit requires careful planning.

Reasonable compensation is required. An S-corporation owner who provides meaningful services to the business generally cannot take an artificially low salary and characterize nearly everything else as a distribution.

At the same time, W-2 wages are not QBI. Paying more wages can reduce the amount of income potentially eligible for the 20% deduction. Once taxable income exceeds the applicable thresholds, the deduction may also be limited by the greater of:

• 50% of W-2 wages, or

• 25% of W-2 wages plus 2.5% of the unadjusted basis of qualified property

That creates a balancing exercise. You need compensation that is reasonable and defensible, while also avoiding unnecessary payroll tax and lost QBI opportunities.

Your quarterly review should ask:

• Is current owner compensation supported by industry data and actual duties?

• Are distributions proportionate and properly documented?

• Does the business have enough W-2 payroll to support the desired QBI deduction?

• Would qualified property provide meaningful UBIA support?

• Are multiple commonly owned businesses eligible for aggregation?

• Is the business a specified service trade or business, where QBI limitations can become more restrictive at higher income levels?

This is where accurate books and current payroll data become essential. A year-end tax return cannot fix a compensation strategy that was mishandled throughout the year.

Our complete bookkeeping services and tax planning process are designed to give business owners timely information before decisions become irreversible.

3. Test Whether Your Business Is Better Served by Pass-Through or Retained Corporate Taxation

Some business owners focus only on the current-year tax bill. That can be shortsighted.

Suppose your company earns $2 million but distributes nearly all of its profits to the owners. Pass-through taxation may be attractive because the income is generally taxed once at the owner level, with potential QBI benefits.

Now suppose the company plans to retain most of its earnings for several years to:

• Purchase equipment

• Open new locations

• Acquire competitors

• Hire a large management team

• Build working capital

• Fund research and development

• Make strategic investments

In that case, the 21% C-corporation rate may deserve a closer look. The lower entity-level rate may allow more cash to remain inside the business for growth.

But the analysis cannot stop there. You must also consider:

• Future dividend taxation

• Tax treatment when the business is sold

• Restrictions on ownership and capital structure

• Potential accumulated earnings concerns

• Whether outside investors will be involved

• Whether the company may qualify for other planning opportunities

• How the structure affects the owners’ estate and wealth plans

There is no universal winner. An S corporation can be highly effective for a profitable, closely held operating company. A C corporation may be more suitable for a growth company that expects to reinvest heavily and delay distributions.

The right decision depends on what you plan to do with the cash after the business earns it.

4. Coordinate Depreciation, Capital Spending, and Interest Deductibility

Entity structure decisions should be tested alongside your capital investment and financing plans.

For 2026, the Section 179 deduction limit is $2.56 million, with the deduction beginning to phase out when qualifying property placed in service exceeds $4.09 million, according to IRS Publication 946.

In addition, 100% bonus depreciation is generally available for qualifying property under the post-OBBBA rules. These provisions can create substantial current-year deductions, but maximizing deductions immediately is not always the best long-term strategy.

Large depreciation deductions can:

• Reduce pass-through income

• Reduce the QBI deduction base

• Affect owner estimated taxes

• Create or increase losses

• Change retirement plan calculations

• Influence the amount of business interest that can be deducted

Section 163(j), the business interest limitation, generally limits deductible business interest to 30% of adjusted taxable income, subject to applicable exceptions and other adjustments. Depending on the business and the rules in effect, the adjusted taxable income calculation may resemble an EBITDA-style measurement more closely than an EBIT-style measurement.

This is especially important for highly leveraged companies. A business that makes a major equipment purchase, takes on debt, and claims accelerated depreciation may not receive the simple tax result it expected.

Before year-end, review:

• Planned equipment and technology purchases

• Real estate acquisitions or improvements

• Debt refinancing and new borrowing

• Expected interest expense

• Bonus depreciation versus Section 179

• The effect of deductions on QBI and taxable income

Tax planning is not just about finding the largest deduction. It is about understanding how several deductions interact.

5. Review State Taxes, Ownership, and Your Exit Strategy

Federal planning is only part of the entity-structure decision.

The OBBBA increased the individual SALT deduction cap to approximately $40,400 for 2026, with limitations and phase-down rules for certain higher-income taxpayers. For owners of pass-through businesses, state tax planning may also involve a pass-through entity tax election.

Many states allow eligible partnerships and S corporations to pay state income tax at the entity level. This may help owners work around the individual SALT cap, although the rules vary significantly by state and the election may reduce pass-through income and QBI.

Your review should also include ownership considerations. S corporations have important restrictions, including limitations involving eligible shareholders and classes of stock. Those restrictions may become a problem if you plan to:

• Bring in institutional investors

• Issue preferred economic rights

• Create complex equity incentives

• Transfer ownership to certain trusts

• Add foreign shareholders

• Raise capital for an acquisition

• Transition ownership to family members or key employees

Finally, consider your exit strategy. The structure that minimizes annual taxes may not produce the best result when you sell the company. Asset sales, stock sales, built-in gains, shareholder basis, debt, and goodwill can all affect the outcome.

If a sale, ownership transfer, or major recapitalization could occur within the next three to five years, it should be part of the 2027 entity review, not an afterthought during negotiations.

Build Your 2027 Entity Plan Before the Year-End Rush

A structure review should result in more than a conversation. It should produce a written action plan.

At a minimum, your team should document:

• Which entity structures were modeled

• Expected revenue, profit, payroll, and distributions

• QBI and reasonable-compensation assumptions

• Planned capital expenditures

• Debt and interest projections

• State tax and SALT considerations

• Ownership and exit objectives

• Required legal, payroll, or tax elections

• Implementation deadlines

If your S-corporation election still fits your business, a review can confirm that your compensation, distributions, payroll, and tax planning are operating properly.

If it no longer fits, early planning gives you time to evaluate alternatives carefully. Conversions can involve tax consequences, legal work, payroll changes, accounting adjustments, and communication with lenders or investors. Waiting until tax filing season is rarely the best approach.
