Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes Income taxes attributable to continuing operations during the three months ended June 30, 2020 and 2019 was an income tax expense of $4.5 million and $5.7 million, respectively, representing effective tax rates of 136.4% and 64.8%, respectively. The difference between the U.S. federal income tax rate of 21.0% and GCP’s overall income tax rate for the three months ended June 30, 2020 was primarily due to the reversal of $3.2 million of tax benefits recognized during the three months ended March 31, 2020 related to the CARES Act, and a tax expense $0.4 million and $0.4 million, respectively, for unrecognized tax benefits and valuation allowances. During the three months ended March 31, 2020 as a result of the CARES Act, the Company recorded a $3.2 million benefit related to the carryback of its anticipated 2020 loss. As a result of changes to its forecasted income during the three months ended June 30, 2020, the Company no longer expects to have a net operating loss carryback for 2020 and has reversed the $3.2 million benefit. The difference between the U.S. federal income tax rate of 21.0% and GCP's overall income tax rate for the three months ended June 30, 2019 was primarily due to $2.2 million of tax expense relating to foreign tax rate differential.

Income taxes attributable to continuing operations during the six months ended June 30, 2020 and 2019 was an income tax expense of $2.6 million and an income tax benefit of $10.7 million, respectively, representing effective tax rates of 89.7% and 148.6%, respectively. The difference between the U.S. federal income tax rate of 21.0% and GCP’s overall income tax rate for the six months ended June 30, 2020 was primarily due to a tax expense of $0.7 million and $1.0 million, respectively, for increases in unrecognized tax benefits and valuation allowances. The difference between the U.S. federal income tax rate of 21.0% and GCP's overall income tax rate for the six months ended June 30, 2019 was primarily due to the finalization of the Transition Tax regulations issued in January 2019, resulting in a tax benefit from the reversal of unrecognized tax benefits in the amount of $20.2 million, partially offset by a tax expense of $3.6 million on changes to GCP’s 2017 income tax liability and Transition Tax.

Tax Reform

As a result of the additional deductions and net operating loss carryback allowable to GCP under the CARES Act, GCP decreased its outstanding Transition Tax liability by $6.2 million during the six months ended June 30, 2020. GCP had previously elected to pay the Transition Tax over the eight-year period as provided in the 2017 Tax Act. As of June 30, 2020, the unpaid balance of the Transition Tax obligation is $35.2 million, net of overpayments and foreign tax credits. After considering overpayments, the outstanding payable is due between April 2023 and April 2025.

During the year ended December 31, 2018, GCP recorded a $20.2 million liability for an unrecognized tax benefits related to certain capital gains recognized as a result of the application of the Transition Tax. As a result of clarifications contained in final regulations issued by the IRS in January 2019, GCP decreased its liability for unrecognized tax benefits by $20.2 million during the three months ended March 31, 2019. For additional information related to the 2017 Tax Act, please refer to Note 9, "Income Taxes," to the Company's Consolidated Financial Statements included in the 2019 Annual Report on Form 10-K.

Repatriation

In general, it is GCP's practice and intention to permanently reinvest the earnings of its foreign subsidiaries and repatriate earnings only when the tax impact is efficient.

Valuation Allowance

        In evaluating GCP's ability to realize its deferred tax assets, GCP considers all reasonably available positive and negative evidence, including recent earnings experience, expectations of future taxable income and the tax character of that income, the period of time over which temporary differences become deductible and the carryforward and/or carryback periods available to GCP for tax reporting purposes in the related jurisdiction. In estimating future taxable income, GCP relies upon assumptions and estimates about future activities, including the amount of future federal, state and foreign pretax operating income that GCP will generate; the reversal of temporary differences; and the implementation of feasible and prudent tax planning strategies. GCP records a valuation allowance to reduce deferred tax assets to the amount that it believes is more likely than not to be realized.

Income tax expense for valuation allowances was $0.4 million for the three months ended June 30, 2020. Such expense was immaterial during the three months ended June 30, 2019. During the six months ended June 30, 2020 and 2019, GCP incurred income tax expense for valuation allowances of $1.0 million and $0.5 million, respectively, recorded against deferred tax assets for prior net operating losses incurred primarily in Australia and India.
