## Impact of OBBBA on Business Entities
The One, Big, Beautiful Bill Act (enacted July 2025) dramatically affects how pass-throughs, S-corps, and LLCs are taxed. Important items include changes to deductible business expenses like meals, limitations on interest deductions under **section 163(j)(8)**, and adjustments to depreciation recapture.

Notably, amortization or depreciation related to qualified property now can be added back when calculating **Adjusted Taxable Income (ATI)** for tax years beginning after **December 31, 2025**. The law also changes definitions of gross income for purposes of IRC §§ 951/951A and treats certain foreign source components differently in the ATI calculation. ([irs.gov](https://www.irs.gov/irb/2026-15_IRB?utm_source=openai))
Businesses should evaluate whether switching entity type (e.g., from partnership to S-corp) matters under the new rules and examine how depreciation or interest deduction caps interact with entity flow-through taxation.
## Key Considerations When Structuring Your Entity
- Entity Tax Classification: Sourcing income through an S-corporation or LLC taxed as S-Corp can change how OBBBA’s definitions apply.
- Depreciation/Amortization: Assets placed in service after Dec 31, 2025 now may be included in ATI, potentially reducing interest deduction limits. Capturing full bonus depreciation under § 168(k) is still time-sensitive. ([irs.gov](https://www.irs.gov/irb/2026-15_IRB?utm_source=openai))
- Meal Deduction Changes: Changes to 50% meal deductions include exceptions for certain types of meals, such as crews on commercial fishing vessels. Choosing entity with adequate meal expense types could preserve more deductions.

## Example: LLC vs S-Corp for Depreciation & Interest Expense
**Scenario:** Jane operates a consulting business with heavy startup costs, buys $100,000 in eligible assets in 2026, and has substantial interest expenses.
- As an LLC taxed as partnership: Jane may leverage full § 168(k) depreciation if assets qualify; interest expense deductions subject to ATI cap but increased flexibility to add back depreciation/amortization beginning 2026. This reduces the limit. If she elects out of certain deductions or issues a different entity classification, results vary.
- As an S Corporation: Similar rules, but flows through profits/losses differently; payroll vs distributions can shift income (and related limitations). Meal deductions and interest expense rules apply across entities.
## Actionable Steps for Small Business Owners
1. Inventory assets placed in service after Jan 1, 2026 to track what qualifies under § 168(k).
2. Chart projected interest expenses vs projected ATI including depreciation and amortization — simulate whether ATI adds back these items and how that impacts deduction limits.
3. Choose entity form considering SALT deduction changes, meal deduction exceptions, and state income tax burdens now that SALT cap increased temporarily under OBBBA.

4. Consult with CPA or tax counsel to file elections timely—especially for depreciation and entity classification.
## Summary
For small business owners, the tax law shift under OBBBA requires reevaluation of entity structure, asset acquisition timing, and expense recognition. By understanding ATI, basis, and deductions, businesses can optimize tax liabilities and preserve cash flow—if they act proactively.
