5 tax-related issues manufacturers should review at midyear

Financially savvy manufacturers understand that tax planning shouldn't take place only at year-end. To make the most of all available tax breaks, you need to evaluate your manufacturing business's midyear position and promptly make necessary adjustments. Here are five federal tax-related issues you should examine.

1. Accelerated depreciation for capital expenditures

100% first-year bonus depreciation is now permanent for eligible new and used assets acquired and placed in service after January 19, 2025. This presents valuable tax-planning opportunities for capital-intensive industries such as manufacturing.

Bonus depreciation is automatically applied to eligible assets unless you elect out of it. You can elect out only on an asset class basis, not for individual assets. For example, you can elect out of bonus depreciation for all so-called five-year property, but you can't elect out for just one specific asset in that class.

The Section 179 expensing election also allows manufacturers to immediately write off the full cost of eligible assets. For 2026, the maximum deduction is $2.56 million, but it begins phasing out on a dollar-for-dollar basis when qualifying purchases exceed $4.09 million. In contrast to bonus depreciation, however, Sec. 179 deductions can't create an overall business tax loss.

It's easier to take a more thoughtful approach to capital investments (including machinery and equipment purchases) at this point in the tax year than to make a rushed purchase in December. You also may be able to negotiate more favorable terms by shopping around now rather than waiting. But be sure to plan your rollout of new purchases carefully — that is, when they're placed in service — to avoid exceeding the Sec. 179 deduction limit.

2. Limited-time tax break for QPP

Manufacturers might also benefit from the new 100% first-year deduction for qualified production property (QPP). To be eligible, among other requirements, 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 allows eligible businesses to immediately deduct the cost of QPP that otherwise would be depreciable over 39 years. Unlike bonus depreciation, the QPP deduction requires an election.

QPP generally is any portion of nonresidential property you use as "an integral part" of a qualified production activity. A qualified production activity involves the manufacturing, production or refining of qualified products. To cut to the chase, QPP generally means factory buildings. However, you don't have to construct a new facility to take advantage of this deduction. Structural building components in eligible production areas may also qualify as QPP, including:

  • Walls, partitions, floors, ceilings and permanent coverings for them (for example, paneling or tiling),
  • Central air conditioning or heating system components,
  • Plumbing and plumbing fixtures,
  • Electrical wiring and lighting fixtures,
  • Stairs, escalators and elevators,
  • Sprinkler systems, and
  • Other components related to the operation or maintenance of a building.

Note that you can't claim the deduction for property used for offices, administrative services, lodging, parking, sales or research activities, software development or engineering activities, or other functions unrelated to a qualified production activity.

3. Immediate expensing for domestic R&E costs

Deductions for domestic research and experimental (R&E) expenses in the year incurred have been permanently restored. Foreign R&E costs remain subject to 15-year amortization.

Sec. 174 R&E expenses also may qualify for the Sec. 41 research tax credit. But 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.

4. Sec. 199A QBI deduction

The Sec. 199A qualified business income (QBI) deduction can free up significant capital for eligible smaller manufacturers to reinvest in their businesses through equipment purchases, research and development, and hiring. The deduction, which is now permanent, generally is available to sole proprietorships and owners of pass-through business entities, such as partnerships, S corporations, and limited liability companies that are treated as sole proprietorships, partnerships or S corporations for tax purposes.

QBI is defined as the net amount of income, gains, deductions and losses, excluding reasonable compensation, certain investment items and payments to partners for services rendered. Qualified taxpayers can deduct up to 20% of their QBI. The deduction is available regardless of whether you itemize deductions, and it also applies for alternative minimum tax purposes.

The QBI deduction is subject to several restrictions. First, it generally can't exceed 20% of your taxable income before the QBI deduction. For 2026, the phase-in range is $201,750 to $276,750 of taxable income ($403,500 to $553,500 for married couples who file joint tax returns).

Second, if your taxable income exceeds the applicable threshold, a wage and investment limit begins to phase in. This means that your QBI deduction may be partially or fully reduced to the greater of your share 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 undepreciated cost 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.

5. Estimated tax payments

It's not uncommon for manufacturers to base their current-year quarterly estimated tax payments on the prior year's income or tax obligation. However, that approach could send you down an unnecessarily costly path.

Instead, consider projecting your actual 2026 tax liability. Factor in your year-to-date income and expenses, revenue and expense projections for the rest of the year, and the anticipated effects of applicable tax deductions and credits.

If your projected taxable income is greater than expected, you'll want to increase your final estimated tax payments for the year to reduce the risk of an underpayment penalty. If it's less than originally estimated, you can trim your payments and improve your cash flow.
