The Accounting and Tax Implications of Tariffs

Tariffs are the new buzzword in global business, but unlike the latest fashion trend, these aren't something companies can just ignore. From raw materials to final products, tariffs are shaking up the cost of doing international business in ways that could leave your clients wondering where their profits went. As a CPA, you’re probably already seeing the impact, but now it’s time to really understand it, and get ahead of it. 

The good news? As the economy navigates this bumpy road, you, the humble CPA, have a massive opportunity to show your clients that you’re not just number crunchers; you’re their strategic advisors. By guiding them through the maze of tariffs and tax implications, you can help them stay on top of their game. 

COGS Under the Tariff Lens

Let’s start with the basics: when a business imports goods, the tariffs it pays are more than just another line item on the expense report. These duties become part of the product's cost of acquisition, and that means they affect inventory valuation and COGS. If your client’s not tracking tariff costs accurately, their financials could be as misleading as a set of false eyelashes on a tax return. 

Here’s the plan: 

Practical Strategy: Track Tariff Costs Like a Pro

• Direct vs. Indirect Tariff Costs: Direct costs, like duty fees, should be tacked onto the cost of the product itself. Indirect costs, like freight charges or broker fees, may be capitalized into inventory but require special care. 
• FIFO vs. LIFO: In a world of rising tariffs, FIFO can leave you holding the higher-cost inventory (not ideal for the bottom line), while LIFO might give you a larger COGS, lowering taxable income, and maybe saving you on taxes. 
• Internal Controls: Set up robust systems to track all tariff-related invoices and documentation. Trust me, keeping things clean from customs to freight forwarders will save your client from the headache of financial restatements.

Tariff Impact on Inventory Valuation Methods

Inventory Method	Effect of Rising Tariffs	Impact on Financial Statements
FIFO	Old, lower-cost inventory sold first	Higher cost inventory stays on balance sheet, leading to higher COGS later
LIFO	New, higher-cost inventory expensed first	Results in higher COGS, lowering taxable income during times of rising tariffs
Weighted Average	Averages cost of goods, including tariff costs	Smoothens out the impact of tariff fluctuations, providing more stability in reporting

 
Financial Statement Presentation and Disclosure

Misclassifying tariffs can make a company’s gross margin look more glamorous than it really is, and let’s face it, nobody likes to get caught dressing up numbers like that. 

Practical Strategy: Classify Tariffs Correctly

• Not SG&A: Whatever you do, don’t treat tariffs as selling, general, and administrative (SG&A) expenses. They’re direct costs of acquiring inventory, and if they’re misclassified, the gross margin gets artificially inflated. Not a good look for your client’s pricing strategy. 
• Enhance Transparency: For companies with significant exposure to tariffs (you know who they are), suggest adding specific disclosures in their financial statements. This isn’t just about compliance; it’s about building trust with stakeholders.

Tax Planning Strategies to Mitigate Tariff Impact

Here’s where you can really earn your stripes. Tariffs raise the cost of goods sold, and with that, taxable income. But don’t panic; with some savvy tax planning, you can turn this into an opportunity. 

Practical Strategy: Get Creative with Tax Planning

• Leverage LIFO: As we mentioned earlier, LIFO is your best friend in rising cost environments. It expenses the higher-cost inventory first, leading to lower taxable income and potentially tax savings. During 2025, inflation and tariffs resulted in LIFO tax benefits that were 2x to 10x higher than historical averages for many companies, especially in inventory-heavy sectors, due to an average effective tariff rate of 18.6%.

• Duty Drawbacks: Help your clients reclaim duties on goods that are later exported. You’d be surprised how many businesses miss this. The paperwork can be a nightmare, but it’s well worth it for companies who import and then export goods. 
• Free Trade Zones & Bonded Warehouses: These zones let companies defer or even eliminate tariffs. By explaining the tax implications of these strategies, you can help clients avoid paying duties upfront, which is like giving them a temporary tax vacation.

Data-Driven Insights and Analysis

You’re not just pushing papers here; you’re using data and analysis to add real, strategic value. Here’s your chance to show clients that you’re not just there for tax prep—you’re helping them plan for the future. 

Practical Strategy: Use Data to Drive Decision-Making 

• Perform Sensitivity Analysis: Model different tariff increases (5%, 10%, 25%) and show clients how they would impact gross margin, operating income, and cash flow. This lets clients see the potential impact of tariffs on their business; before they get the bill. 
• Evaluate Sourcing Strategies: Help clients run the numbers on whether it’s cheaper to keep importing that tariff-heavy product or if sourcing domestically is a better long-term solution. 
• Technology Solutions: Recommend software that automates tariff tracking and reporting. These tools are worth their weight in gold when it comes to cutting down errors and improving reporting accuracy.

"Technology is the secret weapon in mitigating tariff risk. If you're not leveraging the right tools to automate tariff tracking, you're missing out on major opportunities for accuracy and compliance." – Bethany Ward, CPA, Partner at Tax Compliance Group 

Conclusion

Tariffs are no longer just a political talking point; they’re a real business cost that’s here to stay. But for CPA firms, this presents a golden opportunity to go beyond compliance. You’re no longer just the “number crunchers.” You’re the trusted strategic advisor who can help your clients navigate this complex landscape. 

By helping clients with inventory management, financial statement accuracy, and data-driven tax planning, you can turn the complexity of tariffs into a competitive advantage. A proactive, advisory approach isn’t just good for business: it’s how you make your mark in today’s volatile economic environment.
