Income Taxes	Note 8 — Income Taxes Prior to the Stone Combination, Talos Energy LLC was a partnership for U.S. federal income tax purposes and was not subject to U.S. federal income tax or state income tax (in most states) at the entity level. As such, Talos Energy LLC did not recognize U.S. federal income tax expense or state income tax expense in most states. Talos Energy LLC’s operations in the shallow waters off the coast of Mexico were conducted under a different legal form and are subject to foreign income taxes. For the three months ended September 30, 2019, the Company recognized income tax expense of $0.8 million for an effective tax rate of 1.0%. The difference between the Company’s effective tax rate of 1.0% and federal statutory income tax rate of 21% is primarily due to a reduction to the Company’s valuation allowance. For the three months ended September 30, 2018, the Company’s effective tax rate of 0% differed from the federal statutory rate of 21% because the Company recorded a valuation allowance against its deferred tax assets. For the nine months ended September 30, 2019, the Company recognized an income tax expense of $0.4 million for an effective tax rate of 0.7%. The difference between the Company’s effective tax rate of 0.7% and federal statutory income tax rate of 21% is primarily due to a reduction to the Company’s valuation allowance. For the nine months ended September 30, 2018, the Company’s effective tax rate of 0% differed from the federal statutory rate of 21% because the Company recorded a valuation allowance against its deferred tax assets. The Company evaluates and updates the estimated annual effective income tax rate on a quarterly basis based on current and forecasted operating results and tax laws. Consequently, based upon the mix and timing of the Company’s actual earnings compared to annual projections, the effective tax rate may vary quarterly and may make quarterly comparisons not meaningful. The quarterly income tax provision is generally comprised of tax expense on income or benefit on loss at the most recent estimated annual effective tax rate. The tax effect of discrete items is recognized in the period in which they occur at the applicable statutory rate. Deferred income tax assets and liabilities are recorded related to net operating losses and temporary differences between the book and tax basis of assets and liabilities expected to produce deductions and income in the future. The realization of deferred tax assets depends on recognition of sufficient future taxable income in specific tax jurisdictions in which those temporary differences or net operating losses are deductible. When assessing the need for a valuation allowance on deferred tax assets, the Company considers whether it is more likely than not that some portion or all of them will not be realized. As September 30, 2019, the Company had a valuation allowance related to federal, state and foreign deferred tax assets.
