Is Your Business Structure Still the Right One for 2025 and Beyond?

In this guide, we’ll walk through what’s changed for 2025, what each business structure offers, and how to determine if it’s time to make a switch — before the end of the tax year.

‍

Choosing the right business structure isn’t a one-time decision — it’s a strategy that should evolve as your business grows. The structure that worked when you launched your company may not be the one that minimizes taxes or protects your assets best in 2025 and beyond.

With tax law updates from the One Big Beautiful Bill Act (OBBBA) and ongoing IRS adjustments for pass-through entities, now’s the time for business owners to take a closer look at how they’re set up — and what it’s really costing them.

‍

1. Why Your Business Structure Matters

Your entity type affects how much tax you pay, how you pay yourself, and what you can deduct. It also determines your exposure to liability and how easy it is to bring on investors or partners.

‍

Choosing (or keeping) the wrong structure can mean:

‍

Paying unnecessary self-employment taxes
Missing out on pass-through deductions
Overlooking retirement and healthcare savings opportunities
Increased audit risk

‍

Even subtle changes in revenue, headcount, or goals can make another entity type more beneficial.

‍

2. How Business Structures Are Taxed in 2025

Here’s a quick IRS-accurate comparison of how the most common business entities are taxed for 2025:

‍

Business Structure Comparison: Tax Treatment and Key Benefits (2025)
Entity Type	How It's Taxed (2025)	Pros	Cons
Sole Proprietorship	Taxed on owner’s personal return; subject to self-employment tax (15.3%).	Easy setup, full control, low cost.	No liability protection; limited deductions.
LLC (Single-Member)	Default pass-through; taxed on Schedule C; eligible for 20% QBI deduction.	Legal protection, flexible structure, simple compliance.	Subject to self-employment tax unless electing S Corp status.
S Corporation	Pass-through entity; owner takes a “reasonable salary” + distributions (not subject to SE tax).	Potential tax savings on distributions, credibility with lenders, QBI eligible.	Stricter IRS rules, requires payroll setup and formal meetings.
C Corporation	Pays a 21% federal corporate tax rate; dividends taxed again at shareholder level.	Ideal for reinvestment and growth; easier to attract investors; strong liability protection.	Double taxation, complex reporting, potential accumulated earnings tax.
Partnership (LLC or LLP)	Pass-through to partners; each pays tax on share of income; may qualify for QBI deduction.	Flexible management and allocations; good for multi-owner setups.	Requires strong partnership agreement; partners pay SE tax.

3. 2025 Tax Law Updates That May Affect You

‍

The OBBBA (One Big Beautiful Bill Act) and 2025 IRS updates made several changes worth noting:

‍

R&D expenses are once again deductible in the year incurred (not amortized over five years).

Bonus depreciation remains at 60% for property placed in service in 2025.

The Section 179 limit holds steady at $1.22 million with phase-out starting at $3.05 million.

Many states still allow Pass-Through Entity (PTE) tax elections — a valuable SALT cap workaround.

‍

If your business invests in equipment, software, or professional services, these updates could shift which structure gives you the best deduction opportunities.

‍

4. When to Reevaluate Your Structure

A good rule of thumb is to revisit your entity choice every 2–3 years or whenever your revenue jumps significantly. For instance, if your business recently crossed the $100,000 to $200,000 profit mark, you might benefit from converting from a sole proprietorship or single-member LLC to an S-corp to save thousands in self-employment taxes. Likewise, if your business is reinvesting heavily or looking to attract investors, a C-corp could make more sense.

‍

You should also reassess your structure if:

‍

You’ve added or removed partners/shareholders.

You’re planning to sell or expand operations.

You’ve started hiring full-time employees.

You want to qualify for more tax deductions or credits.
