Yes, an S corporation can use accelerated depreciation and certain other deductions to offset higher than expected income, subject to specific rules and limitations. Here’s a comprehensive explanation based on the relevant sources:
1. Accelerated Depreciation Methods
S corporations can use the Modified Accelerated Cost Recovery System (MACRS) to depreciate most tangible property placed in service after 1986. Under MACRS, the most common accelerated methods are:
- 200% Declining Balance (DB) Method: Used for most 3-, 5-, 7-, and 10-year property (nonfarm and farm property placed in service after 2017), switching to straight line when it yields a greater deduction.
- 150% Declining Balance Method: Used for 15- and 20-year property, and for certain farm property placed in service before 2018, or if elected by the taxpayer.
- Straight Line (SL) Method: Used for residential rental property (27.5 years), nonresidential real property (39 years), and when elected for other property classes.
The choice of method and recovery period depends on the asset’s class life and use. Accelerated methods front-load deductions, resulting in higher depreciation expenses in the early years, which can offset higher income in those years.
2. Section 179 Deduction
Section 179 allows an S corporation to elect to expense the cost of qualifying property in the year it is placed in service, rather than depreciating it over time. For 2025, the maximum Section 179 deduction is $2,500,000, reduced dollar-for-dollar by the amount by which the cost of qualifying property placed in service exceeds $4,000,000. The deduction is also limited to the corporation’s taxable income from the active conduct of a trade or business for the year; any excess can be carried forward.
Section 179 can be a powerful tool to offset spikes in income, but it cannot create or increase a loss at the S corporation level. The deduction is passed through to shareholders, who may be subject to their own limitations.
3. Bonus Depreciation
Bonus depreciation (special depreciation allowance) allows for an immediate deduction of a percentage of the cost of qualifying property. For property acquired after January 19, 2025, the bonus depreciation rate is 100%. For property acquired before that date, the rate is 40% for 2025. Bonus depreciation is not subject to a business income limitation and can create or increase a loss at the S corporation level.
4. Other Deductions
S corporations can also deduct other ordinary and necessary business expenses, such as:
- Salaries and wages
- Rent
- Interest
- Repairs and maintenance
- Taxes and licenses
- Employee benefit programs
- Charitable contributions (subject to limitations and pass-through to shareholders)
- Certain start-up and organizational costs (may be amortized or deducted up to a limit)
- Amortization of intangibles
5. Limitations and Considerations
- Section 179 and Bonus Depreciation Order: Section 179 is applied first, then bonus depreciation, then regular MACRS depreciation on the remaining basis.
- Passive Activity and At-Risk Rules: Deductions may be limited at the shareholder level by the passive activity loss rules (IRC §469) and at-risk rules (IRC §465).
- Shareholder Basis: Losses and deductions passed through to shareholders are limited to their basis in the S corporation.
- Alternative Minimum Tax (AMT): Accelerated depreciation may create AMT adjustments for shareholders.
- Listed Property: Special rules apply to listed property (e.g., vehicles, computers) regarding business use and substantiation.
6. Reporting
- Form 1120-S: The S corporation reports depreciation, Section 179, and other deductions on Form 1120-S. Section 179 is reported on Schedule K and passed through to shareholders on Schedule K-1.
- Form 4562: Used to report depreciation and amortization, including Section 179 and bonus depreciation.
7. Planning Considerations
- Timing: Accelerated deductions are most beneficial in years of high income. However, over the asset’s life, total deductions are the same; only the timing changes.
- Shareholder Tax Situation: Since S corporation income and deductions flow through to shareholders, their individual tax situations (basis, passive activity, at-risk, and other limitations) must be considered.
In summary: An S corporation can use accelerated depreciation (MACRS, Section 179, and bonus depreciation) and other ordinary and necessary deductions to offset higher than expected income, subject to statutory limits and ordering rules. These deductions reduce the S corporation’s taxable income, which in turn reduces the income passed through to shareholders. However, the ultimate benefit to shareholders may be limited by their basis, at-risk, and passive activity limitations.
