IMPORTANT NOTICE AND LEGAL DISCLAIMER: This calculator is provided strictly for educational and informational purposes as a general mathematical simulation. It does not constitute legal, financial, tax, or accounting advice, and its use does not establish a professional-client or fiduciary relationship. All outputs are preliminary estimates based entirely on user-provided inputs and current historical assumptions; they are not guarantees of actual tax liability, savings, deductions, or investment performance. Oil and gas taxation is exceptionally complex and governed by volatile commodity pricing, unique individual tax positions (including Passive Activity Loss rules and Alternative Minimum Tax), and highly fluid federal and state regulations—such as Intangible Drilling Cost (IDC) treatment and Percentage Depletion allowances—which are subject to retroactive legislative changes without notice. State severance, ad valorem, and local production taxes are excluded unless explicitly noted otherwise. The owner, developer, and operators of this website expressly disclaim all liability, including any "hold harmless" protections, for financial losses, IRS or state audits, interest, or penalties resulting from actions taken or omitted in reliance on this tool. You are strictly advised to consult a Certified Public Accountant (CPA) or qualified tax attorney prior to making any investment decisions or filing any tax returns.
