Year-end tax planning strategies manufacturers should consider

As year-end approaches, manufacturers should review their tax position before the books close and identify opportunities to reduce their tax burden. Here are some common strategies — including both tried-and-true and more recently available — that you can execute before year end to minimize your business's tax liability.

Purchase assets by year end

Bonus depreciation and the Section 179 expensing election have been valuable tax-cutting tools for manufacturers for years, allowing hefty deductions for eligible purchases placed in service during the tax year. The One Big Beautiful Bill Act (OBBBA) enhanced their potential value. For example, it made permanent the 100% first-year depreciation deduction for new and used assets acquired and placed in service after January 19, 2025.

The OBBBA also increased the limits on Sec. 179 expensing. For 2026, you can deduct up to $2.56 million. The deduction begins to phase out dollar for dollar when qualifying purchases exceed $4.09 million. Remember that you can claim the Sec. 179 election only to offset net income, not to reduce it below zero to create a net operating loss.

Take advantage of the deduction for qualified production property

If you built a new plant or expanded your existing manufacturing facilities in 2026, you may be eligible for a 100% first-year deduction for qualified production property (QPP). Eligible QPP must be placed in service before year end to qualify, so consider wrapping up any projects that are nearing completion by December 31. If facility upgrades or expansions are part of your long-term plans, keep this new tax break in mind for future tax years — it's a limited-time opportunity.

To qualify for the QPP deduction, the property's construction must begin after January 19, 2025, and before January 1, 2029, and it must be placed in service before 2031. This break lets eligible businesses immediately deduct the cost of QPP that would otherwise be depreciated over 39 years. Unlike bonus depreciation, the QPP deduction requires an election.

Among other requirements, QPP must be used as an "integral part" of a qualified production activity (QPA) — meaning the QPA occurs in the physical space of the property. Property used for offices, administrative services, lodging, parking, sales activities, research activities, software development or engineering activities, or storage of finished products isn't ineligible. Additional rules and restrictions may apply.

Leverage research costs

Manufacturers may not realize they're eligible for the Sec. 174 deduction for research and experimental (R&E) expenses. The deduction isn't limited to only taxpayers conducting scientific, technological or similar types of research. Qualified R&E expenses include costs related to activities intended to discover information that would eliminate uncertainty about the development or improvement of a product, including wages, regardless of the industry.

The OBBBA permanently restored the pre-Tax Cuts and Jobs Act treatment of these costs. As a result, you can deduct qualified domestic research expenses in the year the expenses are incurred or paid. (Foreign R&E costs must be amortized over 15 years.) It doesn't matter if the project hasn't been completed by year end.

Your research expenses might also qualify for the Sec. 41 research credit (often called the "research and development" credit). Generally, qualifying activities must involve efforts to develop or improve a product, process, technique, formula, invention or software and satisfy statutory requirements related to technological research and experimentation.

The credit is generally based on certain qualified research expenses, including eligible employee wages, supplies and contract research costs. For manufacturers, activities such as developing new products, improving production processes, testing prototypes or experimenting with materials may qualify. (Costs that are eligible for the research credit are generally narrower than those that qualify for the R&E deduction.)

Note: Manufacturers can't claim both the deduction and the credit for the same expense. If a manufacturer claims the research credit, the R&E deduction generally must be reduced by the amount of the credit. Alternatively, a manufacturer can elect to claim a reduced research credit.

Maximize your QBI deduction

The Sec. 199A qualified business income (QBI) deduction was made permanent under the OBBBA. This break is available for sole proprietors, as well as owners of pass-through entities, such as partnerships, S corporations, and limited liability companies that are treated as sole proprietorships, partnerships or S corporations for tax purposes. It isn't allowed when calculating the owner's adjusted gross income, but it reduces taxable income. In effect, it's treated the same as an allowable itemized deduction (though you don't have to itemize to claim it).

You may already be claiming the QBI deduction for as much as 20% of your QBI. But if your taxable income exceeded the eligibility limit in previous tax years, you should take a second look. The OBBBA expanded the phase-in ranges, so you might qualify for at least a partial deduction this year.

The 2026 phase-in range is $201,750 to $276,750 ($403,500 to $553,500 for joint filers). When taxable income is within the range, a wage and investment limit starts to phase in, partially or fully reducing your QBI deduction to the greater of:

  • 50% of the amount of W-2 wages paid to employees by the qualified business during the tax year, or
  • The sum of 25% of W-2 wages plus 2.5% of the cost (not reduced by depreciation taken) of qualified property.

If your taxable income will be near the phase-in threshold by year end, consider proactive steps to lower it, such as maximizing retirement contributions. Another common strategy is to accelerate business expenses into 2026 and push income to 2027.
