Full Expensing Pays Off as Business Equipment Investment Surges 20.9%

Business investment in equipment surged 20.9% at an annualized rate in the third quarter of 2026, reinforcing the economic case for permanent full expensing under the Working Families Tax Cuts. The sharp increase comes as businesses take advantage of tax provisions that allow them to immediately deduct the cost of qualifying equipment purchases, reducing the tax burden on investment and encouraging expansion.

According to the Bureau of Economic Analysis (BEA), nonresidential fixed investment increased 12.7% in the third quarter, while the broader economy grew at an annualized rate of 3.4%. The investment figures reflect growing business spending on equipment, technology, and other productive assets, with equipment purchases recording particularly strong gains.

The results offer an encouraging early indication of how a tax code that rewards investment can support economic growth.

Full Expensing Strengthens Incentives to Invest

The Working Families Tax Cuts permanently restored 100% bonus depreciation, commonly known as full expensing, allowing businesses to deduct the entire cost of qualifying capital investments in the year they are made. Previously, businesses faced a scheduled reduction in the amount they could immediately deduct, requiring them to recover more of their investment costs through depreciation over several years.

Full expensing lowers the after-tax cost of purchasing machinery, equipment, and other qualifying assets. By allowing businesses to deduct these expenses immediately, the policy improves cash flow and makes new investments more financially attractive.

The benefits extend across industries, particularly among manufacturers, construction companies, and small businesses that depend on expensive equipment to maintain and expand operations. Permanent full expensing provides greater certainty for businesses planning investments that may take years to generate returns.

The third-quarter increase in equipment investment is consistent with the incentives created by this policy, although the economic data do not isolate the precise contribution of the tax changes.

Business Investment Gains Momentum

The increase in equipment spending comes amid a broader expansion in business investment, driven in part by the rapid development of artificial intelligence and the infrastructure needed to support it.

Companies have increased spending on computing equipment, data centers, and related technologies as demand for AI capabilities grows. The investment boom has contributed to stronger economic activity and increased demand for capital equipment.

The BEA reported that investment in intellectual property products increased 8.4% in the third quarter, while nonresidential structures investment rose 5.4%. Overall gross private domestic investment increased 19.4%, reflecting gains in fixed investment and changes in business inventories.

The Committee to Unleash Prosperity has highlighted the strength of the investment expansion as evidence of improving economic conditions. While AI-related spending remains an important contributor, permanent full expensing improves the tax treatment of qualifying investments throughout the economy.

Pro-Growth Tax Policy Supports Long-Term Expansion

Business investment plays an important role in improving productivity and supporting higher wages. Companies that purchase more advanced equipment and adopt new technologies can increase output, lower production costs, and strengthen their competitiveness.

The Working Families Tax Cuts reinforced these incentives by making full expensing permanent, expanding Section 179 expensing limits, and restoring immediate deductions for domestic research and development expenses. Together, these provisions reduce tax barriers to investment and provide businesses with greater certainty when making long-term financial decisions.

The permanence of full expensing is particularly important. Temporary tax provisions can create uncertainty and encourage businesses to shift investment decisions around expiration dates. A permanent deduction allows companies to plan equipment purchases and expansion projects based on business needs rather than anticipated changes in tax law.

The recent investment figures reflect several economic forces, including strong demand for AI infrastructure. Still, the increase in equipment spending demonstrates the importance of maintaining policies that reduce the cost of capital investment and encourage businesses to expand their productive capacity.

CFE Takeaway

The 20.9% surge in equipment investment provides encouraging evidence that American businesses are expanding their productive capacity under a more favorable tax environment. Permanent full expensing under the Working Families Tax Cuts strengthens incentives to purchase equipment, modernize operations, and invest in future growth.

Congress should protect full expensing and other pro-growth tax provisions that encourage private investment. Maintaining these policies will help businesses improve productivity, support higher wages, and strengthen the American economy over the long term.
