Manufacturing Tax Services That Help You Cut Risk And Keep More Profit

Stop paying more manufacturing tax than you owe. Most manufacturers miss R&D credits, equipment deductions, and multi-state savings every year because their CPA isn’t built for manufacturing.

CDH has worked with U.S. manufacturers since 1996. You get a tax strategy built around your operation.

The Tax Realities Manufacturers Face

Most manufacturing businesses carry tax risk that a general CPA won’t catch. The common gaps we see are:

Multi-State Nexus Not Fully Mapped

Economic nexus thresholds now apply to income taxes in many states, beyond sales tax. Most manufacturers haven’t done a full review.

Unclaimed Bonus Depreciation

Bonus depreciation is back at 100% for equipment placed in service after January 19, 2025, under the 2025 One Big Beautiful Bill Act. Section 179 also allows up to $2.56 million in first-year expensing for 2026.

Unclaimed R&D Credits

Section 41 covers process engineering, tooling, and product development. Many manufacturers qualify and never claim a dollar.

Wrong Inventory Valuation Method

The way you value inventory directly affects your taxable income. When material costs rise, some methods result in higher taxable income than others. If yours hasn’t been reviewed recently, you could be overstating what you owe.

Sales Tax Overpayments

Most states exempt manufacturing equipment from sales tax. Overpayments are common and correctable.

Missing Transfer Pricing Documentation

The IRS has sent compliance alerts to approximately 180 foreign-owned U.S. subsidiaries. Without up-to-date documentation, penalties run 20% to 40% before the underlying tax is resolved.

Manufacturing Tax Services Built Around Production Realities

Your operation changes throughout the year. Your tax strategy should, too.

You might buy equipment mid-year, shift your inventory method, or open a facility in a new state. Each move changes your tax position.

CDH plans around those decisions before they happen. We understand UNICAP rules, MACRS depreciation schedules, LIFO elections, and how your capital cycles affect your year-end picture.

You get a tax strategy built around how your plant runs.

Frequently Asked Questions (FAQs)

Below are the questions CFOs and owner-operators most often ask when evaluating CDH as a manufacturing tax partner.

How Much Do Manufacturing Tax Services Cost at CDH?

CDH prices engagements upfront based on entity count, number of states, and complexity. To get a quote for your operation, schedule a call with one of our manufacturing CPAs.

Can CDH Handle Multi-State Tax Filings for Manufacturers?

Yes. CDH’s state and local tax practice covers nexus analysis, apportionment modeling, and active filings across all 50 states.

We work with manufacturers filing in two states or 20, including states with gross-receipts taxes like Ohio, Texas, and Washington.

Does CDH Work With Foreign-Owned and Japanese-Owned U.S. Manufacturers?

Yes, and it’s one of CDH’s most developed practice areas. Our Japan Business Group handles transfer pricing documentation, Illinois 80/20 addback analysis, Form 5472 filings, and parent-company reporting.

Through the Moore Global network, we also coordinate with professionals in Japan and other countries when cross-border work requires it.

How Quickly Can a Manufacturer Start Working With CDH?

Most engagements move from initial call to signed engagement letter in two to three weeks.

We can start mid-year and don’t require a January 1 start date. During the discovery call, we’ll tell you what documents to pull together.

Will CDH Coordinate With Our Existing Controller or Internal Finance Team?

Yes. CDH works alongside your internal team and hands off documentation, compliance calendars, and reporting schedules in formats they can use.

If you’re on Sage Intacct, we can work directly inside your system. We have also dealt with all sorts of manufacturing accounting systems.

What Tax Credits Are Most Often Missed by Manufacturers?

The biggest gaps we see are R&D credits under Section 41, which cover process engineering, tooling, and product development in addition to laboratory research.

First-year bonus depreciation and Section 179 on equipment are also widely missed, as is cost segregation on manufacturing facilities.

Across the U.S., many states offer sales tax exemptions for manufacturers, but qualification rules vary enough that many manufacturers overpay without realizing it.
