Bonus Depreciation Strategy for Real Estate and Business Owners: Bonus Depreciation vs Section 179
When a business buys equipment or a real estate investor improves a property, the tax code usually spreads the deduction over many years. Bonus depreciation and Section 179 are two ways to move some of those deductions forward, sometimes into the first year. A thoughtful bonus depreciation strategy asks more than "how big can this year's deduction be?" It asks whether a larger deduction now is worth less flexibility later, and what you will do with the cash it frees up.
This guide compares bonus depreciation and Section 179, explains when accelerating deductions may help or hurt, and shows how these choices connect to your broader wealth plan.

What Is Bonus Depreciation?
Bonus depreciation allows a business to deduct a percentage of the cost of qualifying property in the year it is placed in service, rather than spreading the full cost over the asset's normal recovery period. Qualifying property generally includes assets with recovery periods of 20 years or less, such as machinery, equipment, furniture, certain vehicles, land improvements, and qualified improvement property inside commercial buildings. Both new and used property may qualify in many cases.
The bonus percentage has changed several times in recent years, and federal legislation enacted in 2025 changed it again. The rate that applies depends on when property is acquired and placed in service, so confirm current rules with your CPA. Bonus depreciation applies automatically unless you elect out for a class of property, and it can create or increase a loss.
What Is Section 179?
Section 179 is an election to expense the cost of qualifying business property in the year it is placed in service, up to an annual dollar limit that phases out when total purchases exceed a threshold. Annual limits apply and are adjusted over time.
Key differences from bonus depreciation:
Income limit. The Section 179 deduction generally cannot exceed taxable income from your active trades or businesses. Unused amounts may carry forward. Bonus depreciation does not have this limit.
Asset-by-asset choice. Section 179 lets you choose which assets, and how much of each, to expense. Bonus depreciation applies to entire classes of property unless you elect out.
Real property improvements. Section 179 can apply to certain improvements to nonresidential buildings, such as roofs, HVAC, fire protection, and security systems, in addition to qualified improvement property.
Residential rentals. Section 179 generally is not available for property used to furnish lodging, which limits its use for many residential rental owners. Bonus depreciation may still apply to qualifying property.
Many businesses use both: Section 179 for targeted assets and bonus depreciation for the rest.
How Real Estate Owners Use Bonus Depreciation
Buildings themselves are depreciated over long periods and do not qualify for bonus depreciation. A cost segregation study can identify components, such as certain fixtures, flooring, and site improvements, that qualify for shorter lives and therefore for bonus depreciation. Our guides to bonus depreciation for a real estate portfolio and cost segregation for large portfolios explain how this works.
Whether those deductions can offset other income depends on the passive activity rules, your level of participation, and whether you qualify for real estate professional status. See how to reduce taxable income using real estate for more.
When a Bonus Depreciation Strategy May Not Help
A bonus depreciation strategy should account for trade-offs:
Future income may be taxed at higher rates. If you expect higher income later, saving deductions for those years may be worth more.
Recapture on sale. Accelerated depreciation reduces your basis. When assets are sold, part of the gain may be taxed as ordinary income or at special rates.
Other benefits may shrink. Lower taxable income can reduce deductions tied to business income, such as the qualified business income deduction.
State differences. Some states, including Wisconsin, have historically not followed federal bonus depreciation, so state and federal depreciation may differ.
Cash flow. Buying assets mainly for a deduction still spends real money.
Multi-year modeling, as described in our guide to bonus depreciation strategy planning, helps weigh these factors.
Turning Tax Savings Into Long-Term Wealth
In most cases, accelerated deductions defer taxes rather than eliminate them. The real benefit often comes from what you do with the cash in the meantime. Investing tax savings in a diversified portfolio, funding retirement plans, or paying down higher-cost debt can turn a timing benefit into lasting value. This is why tax planning and preparation works best alongside wealth management. Owners can also read about business tax planning in Wisconsin.

Frequently Asked Questions
What is a bonus depreciation strategy?
It is a plan for when and how to use bonus depreciation, often alongside Section 179 and cost segregation, based on multi-year income projections, future sale plans, and how the resulting tax savings will be used.
What is the difference between bonus depreciation and Section 179?
Section 179 is an elective, asset-by-asset deduction with an annual limit and a business income limit. Bonus depreciation applies by property class, has no income limit, and can create a loss.
Can bonus depreciation be used on rental property?
The building itself does not qualify, but certain components identified through cost segregation, along with qualifying improvements and equipment, may.
Does bonus depreciation have to be repaid?
Not directly, but accelerated depreciation lowers your basis, which may increase taxable gain and depreciation recapture when the property is sold.
Does Wisconsin follow federal bonus depreciation?
Wisconsin has historically not followed federal bonus depreciation, so state depreciation may differ. Confirm current state rules with your tax professional.
