Tariffs are here to stay. Even with sudden shifts and headline-grabbing changes, importers need a tariff strategy that holds up over time—not a scramble after every announcement. Forvis Mazars helps you see tariffs through a broader business lens, connecting tariff education, opportunity identification, and vendor alignment into one clear plan. Whether you rely on a single broker or a full roster of vendors, you gain transparency and confidence to act.
Here’s what that looks like in practice. Our customs advisory team studies your business, works through your data, and pinpoints where tariff mitigation can protect your margins. We help keep you current as the tariff landscape shifts, folding each change into your strategy before it catches you off guard. When we spot an opportunity, we bring dedicated professionals to the table—our internal teams alongside third-party firms, brokers, and other vendors—and help you execute. Think of us as your educator, strategy support, and concierge for your tariff needs.
Manage the impacts of tariffs with assistance from our suite of curated service offerings.
Customer Refund & Vendor Resolution Support
Forvis Mazars can assist clients in evaluating tariff-related price increases and preparing for vendor discussions. Our services may include developing a reasonable, documented basis to help support a request for a refund, credit, price adjustment, or other commercial resolution from vendors that may have received IEEPA tariff refunds. Potential procedures may include:
- Gathering and analyzing purchase data, invoices, contracts, vendor communications, and other supporting documentation
- Considering relevant tariff drivers, which may include Harmonized Tariff Schedule (HTS) codes, purchase timing, applicable tariff programs or sections, treaties, and country of origin
- Developing an estimated range of tariff-related costs
- Comparing estimated tariff impacts with vendor price changes to help assess whether tariff-related costs may have contributed to the relevant price increases
- Preparing analysis, documentation, and discussion materials to help support vendor negotiations and commercial resolutions
If the customer chooses to pursue litigation or another formal dispute process involving a vendor, Forvis Mazars may be able to provide litigation consulting services to counsel for the customer. In that context, our work may include developing supportable tariff impact analyses, assisting with the quantification of potential damages or recovery amounts, and providing expert witness services when appropriate.
Importer Refund & Customer Resolution Support
Forvis Mazars can assist importers of record in evaluating tariff-related pricing impacts and preparing for customer discussions. Our services may include developing a reasonable, documented basis to help evaluate whether tariff-related costs were passed on to customers and what resolution, if any, may be appropriate to offer. Potential procedures may include:
- Gathering and analyzing import data, customs documentation, tariff payments, sales data, invoices, contracts, customer communications, and other supporting documentation
- Considering relevant tariff drivers, which may include Harmonized Tariff Schedule (HTS) codes, entry timing, applicable tariff programs or sections, treaties, country of origin, and any refund or relief mechanisms available to the importer of record
- Developing an estimated range of tariff-related costs
- Comparing estimated tariff impacts with historical price changes, pricing methodologies, and other cost drivers to help assess whether tariff-related costs may have contributed to customer price changes
- Preparing analysis, documentation, and discussion materials to help support customer negotiations and commercial resolutions
If the importer of record faces threatened or pending litigation, including a class action or another formal dispute process involving customers, Forvis Mazars may be able to provide litigation consulting services to counsel for the importer of record. In that context, our work may include developing supportable tariff impact analyses, assisting with the evaluation or quantification of claimed damages, exposure ranges, or settlement amounts, and providing expert witness services, when appropriate.
Forvis Mazars helps importers transform tariff data into actionable insights. Rather than offering a one-size-fits-all product, we design solutions around your data environment, business priorities, and tariff exposure—helping you improve visibility, reduce manual effort, and make more informed decisions. Our tax transformation team can help you:
- Automate recurring data extraction from ACE or other available import data sources
- Cleanse, standardize, and structure import data for more reliable analysis
- Model potential tariff impacts from rate changes, sourcing decisions, or mitigation strategies
- Flag potential errors, upcoming deadlines, and action items for further review
- Create dashboards that highlight key metrics, trends, exceptions, and opportunities
Our tariff-focused professionals then help you translate the data and dashboards into practical observations for your business. Whether the analysis identifies unexpected HTS code, inconsistent tariff amounts, possible refund opportunities, or areas for further review, we connect the insights to your broader operational and tax objectives.

Accounting Methods & Inventory
The method you choose can help soften the impact of tariffs. Specifically related to inventory, entities should consider whether there is value in converting to the use of a last-in, first-out (LIFO) or lower of cost or market (LCM) method, and confirm they’re appropriately calculating §263A. Because tariffs raise the capitalized cost of fixed assets and inventory, a well-suited approach can help protect your numbers.

State & Local Tax Planning
Tariffs ripple into state and local obligations. We help you plan for sales and use tax, property tax, and apportionment, while spotting credit and incentive opportunities tied to new or expanded U.S. facilities. We also provide domestic structuring guidance, helping you move forward with a clearer of your full tax position.

Business Valuation Amid Tariff Volatility
Tariff uncertainty raises risk and reshapes value. A grounded look at outside economic factors helps deliver a valuation you can stand behind. We advise on estate planning when lower valuations open gifting opportunities, impairment analysis when conditions demand it, and scenario planning for M&A—so every decision rests on supportable conclusions.
