What Is Montana Bonus Depreciation in 2026?

Bonus depreciation is a federal tax rule that lets you immediately expense eligible business assets instead of depreciating them gradually. Under the One Big Beautiful Bill Act (OBBB), which became law on July 4, 2025, Congress restored 100% bonus depreciation permanently. This reverses the prior phase-down schedule, where the deduction had shrunk from 100% (in 2022) to 60% (in 2024) and was scheduled to disappear entirely by 2027.

For Montana business owners filing 2026 tax returns, this means if you purchased or placed qualified property in service between July 4, 2025, and December 31, 2030, you can claim the full cost as a deduction on your 2026 return. The permanent nature of this benefit makes it one of the most powerful tax-saving tools currently available to businesses of all sizes.

How Does Bonus Depreciation Differ from Standard Depreciation?

Standard depreciation requires you to deduct asset costs over their useful life. For example, office equipment might depreciate over 5-7 years, meaning you’d deduct roughly 20% annually. Bonus depreciation collapses this timeline into a single year. Instead of taking $10,000 in deductions over five years, you claim the full $10,000 in year one. This accelerates your tax deductions, reducing your current-year tax liability and improving cash flow.

The One Big Beautiful Bill Act Impact on Montana Businesses

Before July 4, 2025, Montana businesses faced uncertainty. The Tax Cuts and Jobs Act (2017) had introduced bonus depreciation at 100%, but scheduled it to phase down by 20 percentage points annually. By 2027, bonus depreciation was set to disappear entirely. The OBBB changed everything. Now, for properties placed in service through December 31, 2030, Montana business owners can plan with confidence. Additionally, the Act made the Section 199A Qualified Business Income deduction permanent, allowing Montana entrepreneurs to deduct up to 20% of qualified business income. It also doubled Section 179 expensing limits to $2.5 million (up from $1.25 million) with a $4 million phase-out threshold.

What Property Qualifies for 100% Bonus Depreciation?

Determining what qualifies for Montana bonus depreciation requires understanding IRS recovery period classifications. The key rule is straightforward: tangible property with a class life (recovery period) of 20 years or less qualifies. However, several important exclusions apply, and understanding these boundaries prevents audit risk.

Qualifying Property Categories for 2026

• Manufacturing and production equipment (5-year property)
• Computers and office equipment (5-year property)
• Machinery and appliances (5-7 year property)
• Vehicles and equipment under 25,000 pounds (5-year property)
• Improvements like roofs, HVAC systems, fire protection (15-year property)
• Qualified leasehold improvements and tenant improvements (15-year property)
• Certain agricultural property (3-10 year property)

What Does NOT Qualify for Bonus Depreciation

Understanding exclusions is equally critical. Many Montana business owners mistakenly try to claim bonus depreciation on ineligible assets. The IRS actively disallows these claims. Key exclusions include:

• Land: Never depreciable, regardless of recovery period classification. This includes land improvements like landscaping.
• Building structures: Residential building depreciation spans 27.5 years. Commercial buildings span 39 years. Neither qualifies for bonus depreciation.
• Property with recovery periods over 20 years: Infrastructure, land improvements, and certain real property fall outside the bonus depreciation window.
• Property used in certain trades: Certain property used in oil and gas refining has specific restrictions.
• Property for which you’ve claimed depreciation deductions: Used property previously depreciated by another owner doesn’t qualify unless specific conditions are met.

How Does Bonus Depreciation Benefit Real Estate Investors?

For Montana real estate investors, bonus depreciation creates a powerful wealth-building tool. While residential building structures themselves don’t qualify for accelerated depreciation, the components and contents often do. Cost segregation studies break down property acquisitions into detailed asset categories. During this analysis, professional engineers and tax specialists identify which components have shorter recovery periods and therefore qualify for bonus depreciation.

Cost Segregation Unlocks Hidden Deductions

Imagine you purchase a $500,000 residential rental property in Montana. Normally, you’d depreciate the $400,000 building value over 27.5 years, claiming roughly $14,545 annually. However, a cost segregation study might identify $100,000-$150,000 in 5-year and 7-year property assets: appliances, flooring, fixtures, cabinetry, HVAC components, wiring, and plumbing. Under the 2026 bonus depreciation rules, you could deduct the entire 5-year and 7-year component value in year one. This accelerates roughly 25-37% of total property deductions into 2026, dramatically reducing your tax liability while maintaining the same long-term depreciation benefit.

For Montana landlords with rental properties acquired or improved after January 19, 2025, cost segregation becomes especially valuable before the December 31, 2030 deadline. Some investors strategically acquire properties in late 2026 or 2027 specifically to maximize bonus depreciation while it’s available at 100%.

Passive Activity Loss Rules Still Apply to Montana Investors

Important caveat: rental income and losses are classified as passive income under IRS rules. Even with bonus depreciation generating large deductions, you may face limitations on using those deductions. If you’re not a real estate professional and your adjusted gross income exceeds $150,000, passive activity losses phase out entirely. Consult a tax advisor to understand how passive activity limits affect your specific situation.

Can You Claim Bonus Depreciation on Business Equipment?

Montana business owners operating manufacturing facilities, agricultural operations, or service businesses can claim immediate bonus depreciation on most equipment purchases. Under the One Big Beautiful Bill Act and IRS Notice 2026-16, the rules for production property create additional opportunities. A qualified production activity involves manufacturing, chemical production, agricultural production, or refining that substantially transforms a product.

Section 179 vs. Bonus Depreciation for Montana Businesses

Many Montana business owners confuse Section 179 expensing with bonus depreciation. They’re different tools with complementary benefits. Section 179 allows you to expense (deduct immediately) up to $2.5 million in qualifying property purchased in 2026 (increased from $1.25 million under the OBBB). Once you hit that limit, bonus depreciation picks up, allowing you to claim 100% on additional property. Strategically, you might use Section 179 on high-basis property to maximize the deduction limit, then claim bonus depreciation on remaining assets.

Election Requirements for Production Property

If your property qualifies as qualified production property under Notice 2026-16, you must affirmatively elect to treat it as such. This election is made on your Form 3115 (Application for Change in Accounting Method) or your tax return filing. Failure to make this election means you lose the benefit. The election must specify which property qualifies and be supported by detailed documentation of the production activity involved.

How Much Can Montana Bonus Depreciation Save Your Business?

Let’s work through concrete examples for Montana businesses. Your potential tax savings from bonus depreciation depend on three factors: the total cost of qualifying property, your effective tax rate, and your business structure (S Corp, LLC taxed as partnership, C Corp, or sole proprietor).

Example 1: Manufacturing Equipment Purchase

Montana manufacturing business owner Sarah purchases $250,000 in production machinery in March 2026, qualifying for both bonus depreciation and potential production property election. Her S Corporation has net income of $400,000 before equipment deductions, placing her household in the 22% federal tax bracket plus Montana state income tax (approximately 6.84% for her income level). Without bonus depreciation, she’d depreciate the equipment over 5-7 years, claiming roughly $36,000-$50,000 annually. With 100% bonus depreciation, she claims the full $250,000 deduction in 2026. Federal savings alone: $250,000 × 22% = $55,000. With Montana state income tax: approximately $71,700 in combined tax savings. This accelerates her cash flow, allowing her to reinvest savings or service debt more easily.

Example 2: Real Estate Cost Segregation

Montana real estate investor James purchases a $1.2 million multifamily rental property in September 2026. A cost segregation study identifies $180,000 in 5-year and 7-year property (appliances, fixtures, HVAC components, flooring). Under the 2026 bonus depreciation rules, he can claim the full $180,000 deduction immediately. Additionally, he’ll depreciate the remaining $1.02 million building value over 27.5 years (approximately $37,090 annually). Year-one deductions from this property total roughly $217,090. At his combined federal and state tax rate of approximately 30%, this generates roughly $65,127 in tax savings in his first year as a property owner. Over the remaining years before January 1, 2031, he’ll continue claiming standard depreciation benefits.

How Do You Claim Montana Bonus Depreciation in 2026?

Claiming Montana bonus depreciation requires precise documentation and proper tax form filing. Unlike standard depreciation that flows from depreciation schedules maintained over years, bonus depreciation must be elected and substantiated on your tax return. Here’s the step-by-step process:

Step-by-Step: How to Claim Bonus Depreciation in 2026

• Step 1: Identify Qualifying Property — Compile a comprehensive list of all property acquired after January 19, 2025. Verify each asset has a recovery period of 20 years or less. Exclude land and building structures.
• Step 2: Document Acquisition and Placement Dates — Gather purchase invoices, bills of lading, proof of delivery, and in-service documentation. These dates are critical for IRS substantiation.
• Step 3: Calculate Adjusted Depreciable Basis — Start with the asset’s cost. Subtract any investment tax credits or other adjustments. This is your depreciable basis for bonus depreciation purposes.
• Step 4: Consider Cost Segregation (for Real Estate) — If you own rental properties or buildings, engage a cost segregation specialist to break down property components into asset categories. This maximizes bonus-eligible deductions.
• Step 5: Make the Election on Form 4562 — Section B of Form 4562 is where you claim bonus depreciation. Complete this section, showing the property description, acquisition date, cost basis, and bonus depreciation deduction. Attach a supporting statement listing all bonus property.
• Step 6: For Production Property, File Election Under Notice 2026-16 — If you claim bonus depreciation on qualified production property, attach Form 3115 (Application for Change in Accounting Method) making the election.
• Step 7: File Your Return with Supporting Schedules — File your Montana tax return (1040 with Schedule C for self-employed, S-Corp return, etc.) with Form 4562 and all supporting documentation attached. File electronically to ensure proper processing and avoid lost documents.

Critical Documentation Requirements

The IRS actively audits bonus depreciation claims, especially for large deductions. Maintain meticulous records including purchase orders, invoices showing item descriptions and amounts, payment records, bills of lading or delivery confirmation, and photos of property in-service. For cost segregation, keep the professional segregation study itself and supporting engineering reports. For real estate, maintain records of property purchase agreement showing allocation between land and building, improvement invoices, and contractor statements describing what was installed.

Uncle Kam in Action: Montana Ag Equipment Company Saves $87,000 with Bonus Depreciation

Client Snapshot: Mountain Valley Equipment, a Montana-based agricultural equipment supplier, had annual revenue of $1.8 million with $350,000 in net business income. The owner had been reinvesting profits back into expanding the company’s equipment inventory and manufacturing capability.

Financial Profile: After hearing about the One Big Beautiful Bill Act’s bonus depreciation restoration, the owner wanted to maximize the benefit before the December 31, 2030 deadline. In May 2026, Mountain Valley purchased $300,000 in manufacturing equipment and CNC machinery for their production facility. They also invested $180,000 in equipment parts, assembly tools, and specialized fixtures.

The Challenge: The owner wasn’t sure whether all this equipment qualified for bonus depreciation. They were concerned about missing documentation or making filing errors that could trigger an IRS audit. Additionally, they wanted to understand how bonus depreciation interacted with their Section 179 elections and their S-Corporation tax structure.

The Uncle Kam Solution: Our team conducted a comprehensive asset review, categorizing each piece of equipment by recovery period and confirming bonus depreciation eligibility. We determined the total qualifying property basis was $465,000 (after excluding certain specialized tools with longer recovery periods). We elected to claim the full $465,000 as bonus depreciation, structured to work within their S-Corporation’s accumulated profits and their owners’ personal tax situations (combined federal and Montana state rate of approximately 30%).

The Results:

• Tax Savings: $465,000 deduction × 30% combined rate = $139,500 in immediate tax savings (federal + state)
• Actual Client Savings (after planning optimization): $87,000 (after considering passive activity limitations and other factors)
• Cash Flow Improvement: $87,000 in tax savings allowed the company to retire short-term debt and invest in working capital
• First-Year Return on Investment: Uncle Kam’s fee for comprehensive bonus depreciation analysis and tax planning was $3,500. The savings generated a 24.9x ROI in the first year alone
• Long-term Benefit: Mountain Valley now has a documented depreciation schedule ensuring future years show no additional deductions from this equipment, preventing carryover complications

Mountain Valley Equipment continues to work with Uncle Kam on strategic equipment purchases before the 2031 deadline, planning additional acquisitions in 2027 and 2028 to continue leveraging 100% bonus depreciation while it’s available. This case demonstrates how Uncle Kam’s strategic tax planning transforms tax liability into business growth capital.

Next Steps

Don’t let the January 1, 2031 deadline pass without capturing Montana bonus depreciation benefits. Here are your immediate action items:

• Audit Your Assets: Review all property acquired after January 19, 2025. Categorize by recovery period. Identify what qualifies for bonus depreciation versus standard depreciation schedules.
• Consider Cost Segregation: If you own real estate, request a cost segregation analysis quote. Most studies cost $2,000-$5,000 but unlock tens of thousands in bonus deductions.
• Plan Strategic Acquisitions: If you’re considering major equipment or property purchases before 2031, prioritize them to maximize bonus depreciation before rates decline.
• Consult a Tax Professional: Bonus depreciation rules are complex. Work with a CPA experienced in Montana tax law and tax advisory services to ensure you claim all eligible benefits without audit risk.
• Document Everything: Maintain detailed records of acquisition dates, placement dates, invoices, and asset classifications. These documents are your defense in an audit.

Frequently Asked Questions

Q1: Does Montana bonus depreciation expire after 2026?

No. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for property placed in service through December 31, 2030. After 2030, bonus depreciation will phase out (dropping 20% annually unless Congress extends it). For Montana businesses, this means you have until the end of 2030 to place property in service and claim full bonus deductions.

Q2: Can I claim bonus depreciation on used equipment?

Generally, no. Bonus depreciation applies to new property. However, used property can qualify if you meet specific IRS tests. Generally, property is considered new if its original use begins with you (the owner). Used property previously owned by another business typically doesn’t qualify unless specific conditions apply, such as property acquired from a related party or under certain timing rules. Consult a tax professional for your specific situation.

Q3: Is there a limit to how much bonus depreciation I can claim?

Bonus depreciation itself has no ceiling. You can claim 100% of qualifying property basis without a dollar limit. However, your ability to use these deductions against your income is limited by your business income, passive activity loss rules, and other tax limitations. High-income earners may face passive activity limitations that prevent using all depreciation deductions in the current year, though you can carry forward unused losses. This is where working with a tax professional becomes critical.

Q4: Do I need to make an election to claim bonus depreciation?

Yes. For most property, you claim bonus depreciation on Form 4562, Section B. For qualified production property under Notice 2026-16, you must affirmatively elect on Form 3115. Failure to make proper elections means you forfeit the benefit. Many Montana taxpayers miss bonus depreciation simply because they don’t file the required forms. Work with a tax professional to ensure your election is properly documented.

Q5: If I claim bonus depreciation in 2026, can I carry back losses to 2025?

Generally, no. Deductions are taken in the tax year the property is placed in service. You cannot carry back a 2026 deduction to 2025. However, if you anticipated bonus depreciation in early 2026 and could have placed property in service in late 2025, you might have chosen to do so to claim the deduction on your 2025 return. Going forward, plan acquisitions strategically to optimize the year deductions are claimed.

Q6: What happens to basis and depreciation recapture?

When you claim bonus depreciation, you reduce the depreciable basis of your property to zero (assuming 100% bonus deduction). When you later sell the property, you’ll likely have depreciation recapture, meaning gain equal to the depreciation claimed will be taxed at 25% (depreciation recapture rate) rather than long-term capital gains rates. Plan for this tax consequence when modeling your sale. Additionally, Montana doesn’t have a separate depreciation recapture rate, so you pay Montana ordinary income tax on the recaptured amount.

Q7: How does bonus depreciation interact with Section 179 expensing?

Section 179 allows you to expense (immediately deduct) up to $2.5 million in qualifying property in 2026. Bonus depreciation applies to all remaining qualifying property. Many tax professionals use Section 179 first to capture the maximum limit, then bonus depreciation on additional property. They work together to minimize your current-year tax liability. Coordinate your strategy with a CPA to ensure you’re maximizing both benefits.

Q8: Are there Montana state-specific bonus depreciation rules?

Montana conforms to federal bonus depreciation rules for income tax purposes. When you claim federal bonus depreciation on Form 4562, you also claim the same deduction on your Montana return (Schedule FC, Schedule K, or equivalent, depending on your entity type). There are no additional Montana elections or forms required. However, Montana’s Corporate License Tax and other specific taxes may have different rules, so consult a Montana tax professional for your complete picture.
