Manufacturing Tax Planning decided before year end.
For manufacturers who want inventory rules, equipment purchases, and research activity planned ahead, not sorted out at filing time.
Manufacturing tax planning starts with inventory. §263A generally requires manufacturers to capitalize direct and indirect production costs into inventory, but businesses that meet the §448(c) gross receipts test are exempt and may use simpler §471(c) methods. From there, federal tax law enacted in 2025 restored immediate expensing for qualifying equipment and for domestic research and experimental costs, and the §41 research credit may reward product and process work your team already does. TreeStar reviews these rules with you during the year, models the effect of each decision, and keeps California differences in view.
Where it gets complicated
- 01 Crossing the gross receipts line
Growth can carry a manufacturer past the small business threshold, bringing §263A capitalization and other method changes with it. Spotting that early leaves time to plan the transition.
- 02 Equipment timing
Immediate expensing can produce a large federal deduction in the year a machine is placed in service, but California does not follow federal bonus depreciation. Federal and state depreciation then differ for years, and the plan needs to account for both.
- 03 Research that goes unclaimed
Developing a new product or improving a process may involve qualified research. Without project records and wage tracking, a credit that may be available is hard to support.
- 04 Entity and owner effects
Whether the business is an S corporation, a partnership, or a C corporation changes how credits and deductions reach the owners. A plan that ignores the owners' own returns is only half a plan.

Common questions
Does §263A apply to my manufacturing business?
It generally applies to manufacturers, but businesses that meet the §448(c) gross receipts test are exempt. The threshold is adjusted for inflation, so we confirm the current figure and your average receipts each year.
Can a small manufacturer claim the research credit?
Possibly. The §41 credit looks at qualified research activities and related costs, not company size. Some newer, smaller companies may also be able to apply part of the credit against payroll taxes, and we review whether that election fits.
What changed for equipment and research costs in 2025?
Federal tax law enacted in 2025 restored immediate expensing for qualifying equipment and for domestic research and experimental costs. The details depend on when property was acquired and placed in service and how costs are classified, so we review each purchase and project.
