Tax Services

  • Property Tax

    Mining companies face some of the most complex property tax challenges in any industry. With operations spread across remote land, multiple jurisdictions, and variable asset types—from open-pit mines to processing plants—assessors often lack the context to fairly value mining assets. This can lead to inflated assessments, misclassified equipment, and inconsistent treatment of unitary or centrally assessed property.

    DMA helps mining organizations:

    • Challenge overvaluations and ensure fair treatment of real and personal property through Assessment Review & Appeal
    • Navigate the valuation of land tied to mineral rights, heavy equipment, and processing infrastructure
    • Address unitary assessment and apportionment issues with state and provincial authorities
    • Support planning and valuation strategies throughout the project lifecycle, from site development to reclamation

    For clients managing portfolios across the U.S. and Canada, DMA provides centralized Portfolio Management & Administration to streamline tax budgeting, assessment tracking, and appeal coordination—ensuring consistency and transparency across your entire asset base.

    Transaction Tax

    Our team delivers analysis and tailored research on transaction tax issues to support your tax administration efforts. Our transaction tax experts ensure compliance with multi-jurisdictional tax laws, providing actionable insights and detailed guidance to address complex tax scenarios. In the mining industry, we help businesses address tax challenges related to the purchase of equipment, fuel, and other resources, ensuring that exemptions are properly applied and taxability issues are managed. Our expertise helps optimize tax strategies, reduce risks, and ensure compliance with industry-specific regulations across multiple jurisdictions.

    Fixed Asset Verification

    Mining companies maintain extensive inventories of heavy machinery, mobile equipment, processing systems, and infrastructure—often across remote or difficult-to-access locations. Over time, inaccurate asset records, ghost assets, and misclassifications can lead to inflated property tax liabilities, audit exposure, and misaligned depreciation schedules.

    DMA’s Asset Verification Service helps mining companies:

    • Identify and remove non-existent or retired assets from tax and accounting ledgers
    • Correct asset classifications to reflect true use, condition, and taxability
    • Improve data accuracy across property tax, financial reporting, and fixed asset systems

    Whether verifying equipment at mine sites, processing plants, or logistics hubs, DMA ensures your asset data is reliable, audit-ready, and aligned with your tax and compliance objectives.

    Income Tax

    Through our alliance with GTM, DMA offers Income Tax Advisory service to help mining companies reduce tax exposure, uncover savings, and maintain compliance through tailored strategies. From tax recovery and nexus studies to optimizing tax positions, we identify credits and incentives that enhance your financial standing while ensuring full regulatory compliance.

  • Property Tax

    Mining companies face frequent audits and reassessments—especially for assets subject to unitary or centrally assessed valuation. Disputes often arise from misunderstood production infrastructure, mineral rights, or cost basis assumptions, leading to overassessments and tax overpayments.

    DMA’s Property Tax Audit Management service helps mining organizations:

    • Respond to audits efficiently and defend fair valuation treatment
    • Address improper asset classifications and depreciation schedules
    • Resolve inconsistencies in valuation of surface operations, underground assets, and processing facilities

    DMA also performs historical assessment reviews to identify and recover overpayments caused by obsolete equipment, ghost assets, or overvalued land tied to reserves. Our team ensures clients recover what they’ve overpaid and avoid future tax exposure—backed by deep experience in extractive industries.

    Unclaimed Property Asset Recovery

Due to the complex taxability of resources and equipment, businesses in this sector often encounter overpayments caused by misapplied exemptions or incorrect tax treatment. We also provide audit support, assisting with tax authority inquiries, ensuring compliance with local and regional regulations, and reducing exposure to future audit risks.
