Income Taxes	9 Months Ended
Dec. 31, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's income tax expense (benefit) was $3 million and $(365) million for the three months ended December 31, 2018 and December 31, 2017, respectively, and $205 million and $(303) million for the nine months ended December 31, 2018 and December 31, 2017, respectively. For the three months ended December 31, 2018, the primary drivers of the effective tax rate ("ETR") were the global mix of income, the net decrease in valuation allowances on certain foreign deferred tax assets, and the decrease in transition tax liability. For the nine months ended December 31, 2018, the primary drivers of the ETR were the global mix of income, the net decrease in valuation allowances on certain foreign deferred tax assets, the decrease in transition tax liability, the filing of the October 31, 2017 U.S. federal tax return and the impact of U.S. proposed regulations on the ability to claim certain foreign tax credits. For the three and nine months ended December 31, 2017, the primary drivers of the ETR were the remeasurement of deferred tax assets and liabilities as a result of the Act, the remeasurement of a deferred tax liability relating to the outside basis difference of HPES foreign subsidiaries, the accrual of a one-time transition tax on estimated unremitted foreign earnings and India dividend distribution tax (DDT) accrual on historic earnings and taxes. As of each reporting date, management weighs new evidence, both positive and negative, that could affect its view of the future realization of its net deferred tax assets. Objective verifiable evidence, which is historical in nature, carries more weight than subjective evidence, which is forward looking in nature. As of March 31, 2018, DXC's net deferred tax assets in certain DXC German entities were primarily the result of net operating loss carryforwards, pension, restructuring and other miscellaneous accruals. A full valuation allowance was recorded against these net deferred tax assets as of that reporting date. For the period ended December 31, 2018, management has determined that the positive evidence, including the duration of current profitability due to realization of cost synergies relating to the HPES Merger, a legal entity restructuring allowing the future utilization of net operating loss carryforwards and the nonrecurring nature of the factors that primarily drove historical losses, outweighs the negative evidence of a three-year cumulative loss. Therefore, as of December 31, 2018, management has had a change in judgment and has concluded that it is now more likely than not that the net deferred tax assets in these DXC German entities will be fully utilized. As a result, we have recorded a valuation allowance release of $113 million. This is comprised of $18 million related to current year utilization of net operating loss carryforwards recorded through the annual effective tax rate and $95 million recorded as a discrete income tax benefit in the current period. On December 22, 2017, the President of the United States signed into law comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the "Act"). The Act makes significant changes to the Internal Revenue Code of 1986 with varying effective dates. The Act reduces the maximum corporate income tax rate to 21% effective as of January 1, 2018, requires companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries, broadens the tax base, generally eliminates U.S. federal income taxes on dividends from foreign subsidiaries, creates a new limitation on the deductibility of interest expense, limits the deductibility of certain executive compensation, and allows for immediate capital expensing of certain qualified property. It also requires companies to pay tax on certain foreign earnings of foreign subsidiaries and subjects certain payments from U.S. corporations to foreign related parties to additional taxes. U.S. generally accepted accounting principles require companies to revalue their deferred tax assets and liabilities with resulting income tax effects accounted for in the reporting period of enactment including retroactive effects. The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Act effective in the reporting period of enactment. SAB 118 provides a measurement period that should not extend beyond one year from the Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Act was incomplete but it was able to determine a reasonable estimate, it was required to record a provisional estimate in the financial statements. If a company was not able to determine a provisional estimate to include in the financial statements, it was required to continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Act. While the measurement period under SAB 118 is now closed, DXC may in future periods need to further refine the Company's U.S. federal and state calculations, related to the Act, as the taxing authorities provide additional guidance and clarification. The taxing authorities issued additional guidance after the balance sheet date relating to the Act. DXC believes this guidance constitutes a subsequent event and will be accounted for in the period it was issued. DXC is not able to estimate the financial statement impact as time is needed to interpret the guidance and assess the impact. However, as of December 31, 2018, DXC's accounting for the Act is complete based on the Company's interpretation of the guidance issued as of the balance sheet date. As noted in the Company's fiscal 2018 Annual Report on Form 10-K, the Company was able to record provisional amounts related to certain effects of the Act, as noted below. For the following items, DXC did not record any additional material measurement period adjustments during the three month period ended December 31, 2018: Capital expensing: During fiscal 2018 the Company recorded a provisional benefit of $87 million, which was based on its intent to fully expense all qualifying capital expenses for U.S. federal income tax purposes. This resulted in a decrease of approximately $87 million to the Company's current income taxes payable and a corresponding increase in its net deferred tax liabilities. During Q3 FY19, the Company finalized its estimate of the impact of the law change for purposes of SAB 118 and determined the incremental benefit of capital expensing was approximately $61 million. This resulted in a decrease of approximately $61 million to the Company's current income taxes payable and a corresponding increase in its net deferred tax liabilities. The Company filed its October 31, 2017 U.S. federal tax return and several of its state tax returns in the periods ending September 30, 2018 and December 31, 2018, respectively. In the three months ended December 31, 2018 the Company completed all of the computations necessary, including an analysis of expenditures that qualify for immediate expensing, noting no measurement period adjustments recorded. Executive compensation: As a result of changes made by the Act, starting with compensation paid in fiscal 2019, Section 162(m) will limit compensation deductions, including performance-based compensation, in excess of $1 million paid to anyone who, starting in 2018, serves as the Chief Executive Officer or Chief Financial Officer, or who is among the three most highly compensated executive officers for any fiscal year. The only exception to this rule is for compensation that is paid pursuant to a binding contract in effect on November 2, 2017 that would have otherwise been deductible under the prior Section 162(m) rules. Accordingly, any compensation paid in the future pursuant to new compensation arrangements entered into after November 2, 2017, even if performance-based, will count towards the $1 million fiscal year deduction limit if paid to a covered executive. During fiscal 2018, the Company recorded a provisional income tax expense estimate of $2 million for executive compensation relating to the change in covered individuals. The Company completed an analysis of the binding contract requirement on the various compensation plans and determined the impact of the law change was not material. As part of the fiscal 2019 forecasted ETR, the Company has estimated the IRS Code Section 162(m) adjustment under the new guidance for compensation arrangements entered into after November 2, 2017. Reduction of US federal corporate income tax rate: As discussed above, the Act reduces the corporate tax rate to 21%, effective January 1, 2018. For certain deferred tax assets and deferred tax liabilities, the Company previously recorded a provisional deferred income tax discrete benefit of $338 million, resulting in a $338 million decrease in net deferred tax liabilities as of March 31, 2018. The Company filed its October 31, 2017 U.S. federal income tax return in the period ending September 30, 2018 which impacted the provisional amount recorded. The adjustment was not material. The Company finalized its analysis of the scheduling of the deferred tax assets and liabilities and determined the impact was not material. No additional measurement period adjustments were recorded during the period ended December 31, 2018. For the following provisional items, incremental measurement period adjustments were recognized during the three-month period ended December 31, 2018: Deemed repatriation transition tax: The deemed repatriation one-time transition tax is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of certain of the Company's non-U.S. subsidiaries. To determine the amount of the transition tax, the Company determined, in addition to other factors, the amount of post-1986 E&P of the relevant non-U.S. subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings and the impact of various guidance including proposed regulations. The Company was able to calculate the transition tax and recorded a provisional transition tax obligation of $361 million in fiscal 2018. Due to the revised E&P and cash computations that were completed during the reporting periods, DXC recognized an additional measurement-period adjustment to the transition tax obligation of $25 million for the three months ended June 30, 2018. During the three month period ending December 31, 2018, the Company has recorded a corresponding adjustment of $(70) million. The effect of the total measurement-period adjustments of $(45) million for the nine months ended December 31, 2018 on the fiscal 2019 effective tax rate is (3.88)%. The transition tax, which has now been determined to be complete, resulted in recording a total transition tax obligation of $316 million of which $324 million was recorded as income tax liability and $(8) million recorded as an unrecognized tax benefit receivable. Indefinite reinvestment assertion: Beginning January 1, 2018, the Act provides a 100% deduction for dividends received from 10-percent owned non-U.S. corporations by U.S. corporate shareholders, subject to a one-year holding period. Although such dividend income is now generally exempt from U.S. federal income tax for U.S. corporate shareholders, companies must still account for the tax consequences of outside basis differences and other tax impacts of their investments in non-U.S. subsidiaries. During fiscal 2018 the Company recorded a provisional estimate for those subsidiaries for which DXC were able to make a reasonable estimate of the tax effects of such repatriation for withholding taxes, state taxes, and India dividend distribution tax of $12 million, $7 million and $80 million, respectively. For the three months ended December 30, 2018, the Company recognized an additional measurement-period adjustment of $9 million for state tax purposes recorded to discrete income tax expense. The Company has completed its analysis of the non-U.S. tax rules for certain non-U.S. subsidiaries for U.S. federal and state tax purposes for all material provisional amounts during the measurement-period. Global intangible low taxed income ("GILTI"): The Company continues to evaluate the impact of the GILTI provisions under the Act, which are complex and subject to continuing regulatory interpretation by the IRS. The Company is required to make an accounting policy election of either (i) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the “period cost method”) or (ii) factoring such amounts into the Company’s measurement of its deferred taxes (the “deferred method”). The Company has determined that it will account for the new GILTI tax rules under the period cost method. The income tax expense associated with discontinued operations was $0 million and $24 million for the three months ended December 31, 2018 and December 31, 2017, respectively. The tax expense associated with discontinued operations was $18 million and $96 million for the nine months ended December 31, 2018 and December 31, 2017, respectively. The primary driver of the variance in the tax expense for these periods was the difference in income before tax for the respective periods. The income tax assets and liabilities that were part of the balances classified as assets and liabilities of discontinued operations and that were distributed in the Separation of USPS include $154 million of deferred tax liabilities, $60 million of uncertain tax position liabilities, including interest, and income tax receivables of $162 million. In connection with the Separation, the Company entered into a tax matters agreement with Perspecta. Pursuant to the tax matters agreement, the Company generally will be responsible for tax liabilities arising prior to the Separation of USPS. Income tax liabilities transferred to Perspecta primarily relate to pre-HPES Merger periods, for which the Company is indemnified by HPE for these liabilities, pursuant to the tax matters agreement between the Company and HPE. The Company is also liable to HPE for tax receivables and refunds which it receives from Perspecta related to pre-HPES Merger periods that were transferred to Perspecta. Pursuant to the tax matters agreement with Perspecta, the Company recorded a tax indemnification receivable from Perspecta of $162 million and a tax indemnification payable to Perspecta of $74 million related to income tax and other tax liabilities. The Company continues to have indemnification balances to and from HPE for the same amounts as a result of the HPES Merger. The IRS is examining CSC's federal income tax returns for fiscal 2008 through 2017. With respect to CSC's fiscal 2008 through 2010 federal tax returns, the Company previously entered into negotiations for a resolution through settlement with the IRS Office of Appeals. The IRS examined several issues for this audit that resulted in various audit adjustments. The Company and the IRS Office of Appeals have an agreement in principle as to some, but not all of these adjustments. The Company has agreed to extend the statute of limitations associated with this audit through November 30, 2019. In October 2018, the HPES IRS exam related to fiscal years 2008 and 2009 was resolved resulting in a refund received by Perspecta that relates to a pre-HPES merger period. The refund received by Perspecta reduced the $162 million indemnification receivable from Perspecta and correspondingly reduced the indemnification payable to HPE by approximately $68 million. In addition, during the first quarter of fiscal 2018, the Company received a Revenue Agent’s Report with proposed adjustments to CSC's fiscal 2011 through 2013 federal returns. The Company has filed a protest of certain of these adjustments to the IRS Office of Appeals. The Company has agreed to extend the statute of limitations associated with this audit through July 31, 2019. The IRS is also examining CSC's fiscal 2014 through 2017 federal income tax returns. The Company has not received any adjustments for this cycle. The Company continues to believe that its tax positions are more-likely-than-not sustainable and that the Company will ultimately prevail. In addition, the Company may settle certain other tax examinations, have lapses in statutes of limitations, or voluntarily settle income tax positions in negotiated settlements for different amounts than the Company has accrued as uncertain tax positions. The Company may need to accrue and ultimately pay additional amounts for tax positions that previously met a more-likely-than-not standard if such positions are not upheld. Conversely, the Company could settle positions by payment with the tax authorities for amounts lower than those that have been accrued or extinguish a position through payment. The Company believes the outcomes that are reasonably possible within the next 12 months may result in a reduction in liability for uncertain tax positions of $19 million, excluding interest, penalties and tax carry-forwards.

Income Taxes

The Company's income tax expense (benefit) was $3 million and $(365) million for the three months ended December 31, 2018 and December 31, 2017, respectively, and $205 million and $(303) million for the nine months ended December 31, 2018 and December 31, 2017, respectively. For the three months ended December 31, 2018, the primary drivers of the effective tax rate ("ETR") were the global mix of income, the net decrease in valuation allowances on certain foreign deferred tax assets, and the decrease in transition tax liability.

Therefore, as of December 31, 2018, management has had a change in judgment and has concluded that it is now more likely than not that the net deferred tax assets in these DXC German entities will be fully utilized. As a result, we have recorded a valuation allowance release of $113 million. This is comprised of $18 million related to current year utilization of net operating loss carryforwards recorded through the annual effective tax rate and $95 million recorded as a discrete income tax benefit in the current period.

As noted in the Company's fiscal 2018 Annual Report on Form 10-K, the Company was able to record provisional amounts related to certain effects of the Act, as noted below.

For the following items, DXC did not record any additional material measurement period adjustments during the three month period ended December 31, 2018:

Capital expensing: During fiscal 2018 the Company recorded a provisional benefit of $87 million, which was based on its intent to fully expense all qualifying capital expenses for U.S. federal income tax purposes. This resulted in a decrease of approximately $87 million to the Company's current income taxes payable and a corresponding increase in its net deferred tax liabilities.

This resulted in a decrease of approximately $61 million to the Company's current income taxes payable and a corresponding increase in its net deferred tax liabilities. The Company filed its October 31, 2017 U.S. federal tax return and several of its state tax returns in the periods ending September 30, 2018 and December 31, 2018, respectively. In the three months ended December 31, 2018 the Company completed all of the computations necessary, including an analysis of expenditures that qualify for immediate expensing, noting no measurement period adjustments recorded.

Executive compensation: As a result of changes made by the Act, starting with compensation paid in fiscal 2019, Section 162(m) will limit compensation deductions, including performance-based compensation, in excess of $1 million paid to anyone who, starting in 2018, serves as the Chief Executive Officer or Chief Financial Officer, or who is among the three most highly compensated executive officers for any fiscal year. The only exception to this rule is for compensation that is paid pursuant to a binding contract in effect on November 2, 2017 that would have otherwise been deductible under the prior Section 162(m) rules. Accordingly, any compensation paid in the future pursuant to new compensation arrangements entered into after November 2, 2017, even if performance-based, will count towards the $1 million fiscal year deduction limit if paid to a covered executive. During fiscal 2018, the Company recorded a provisional income tax expense estimate of $2 million for executive compensation relating to the change in covered individuals. The Company completed an analysis of the binding contract requirement on the various compensation plans and determined the impact of the law change was not material. As part of the fiscal 2019 forecasted ETR, the Company has estimated the IRS Code Section 162(m) adjustment under the new guidance for compensation arrangements entered into after November 2, 2017.

Reduction of US federal corporate income tax rate: As discussed above, the Act reduces the corporate tax rate to 21%, effective January 1, 2018. For certain deferred tax assets and deferred tax liabilities, the Company previously recorded a provisional deferred income tax discrete benefit of $338 million, resulting in a $338 million decrease in net deferred tax liabilities as of March 31, 2018. The Company filed its October 31, 2017 U.S. federal income tax return in the period ending September 30, 2018 which impacted the provisional amount recorded. The adjustment was not material. The Company finalized its analysis of the scheduling of the deferred tax assets and liabilities and determined the impact was not material. No additional measurement period adjustments were recorded during the period ended December 31, 2018.

For the following provisional items, incremental measurement period adjustments were recognized during the three-month period ended December 31, 2018:

Deemed repatriation transition tax: The deemed repatriation one-time transition tax is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of certain of the Company's non-U.S. subsidiaries. To determine the amount of the transition tax, the Company determined, in addition to other factors, the amount of post-1986 E&P of the relevant non-U.S. subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings and the impact of various guidance including proposed regulations. The Company was able to calculate the transition tax and recorded a provisional transition tax obligation of $361 million in fiscal 2018. Due to the revised E&P and cash computations that were completed during the reporting periods, DXC recognized an additional measurement-period adjustment to the transition tax obligation of $25 million for the three months ended June 30, 2018. During the three month period ending December 31, 2018, the Company has recorded a corresponding adjustment of $(70) million. The effect of the total measurement-period adjustments of $(45) million for the nine months ended December 31, 2018 on the fiscal 2019 effective tax rate is (3.88)%. The transition tax, which has now been determined to be complete, resulted in recording a total transition tax obligation of $316 million of which $324 million was recorded as income tax liability and $(8) million recorded as an unrecognized tax benefit receivable.

Indefinite reinvestment assertion: Beginning January 1, 2018, the Act provides a 100% deduction for dividends received from 10-percent owned non-U.S. corporations by U.S. corporate shareholders, subject to a one-year holding period.

During fiscal 2018 the Company recorded a provisional estimate for those subsidiaries for which DXC were able to make a reasonable estimate of the tax effects of such repatriation for withholding taxes, state taxes, and India dividend distribution tax of $12 million, $7 million and $80 million, respectively. For the three months ended December 30, 2018, the Company recognized an additional measurement-period adjustment of $9 million for state tax purposes recorded to discrete income tax expense. The Company has completed its analysis of the non-U.S. tax rules for certain non-U.S. subsidiaries for U.S. federal and state tax purposes for all material provisional amounts during the measurement-period.

Global intangible low taxed income ("GILTI"): The Company continues to evaluate the impact of the GILTI provisions under the Act, which are complex and subject to continuing regulatory interpretation by the IRS. The Company is required to make an accounting policy election of either (i) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the “period cost method”) or (ii) factoring such amounts into the Company’s measurement of its deferred taxes (the “deferred method”). The Company has determined that it will account for the new GILTI tax rules under the period cost method.

The income tax expense associated with discontinued operations was $0 million and $24 million for the three months ended December 31, 2018 and December 31, 2017, respectively. The tax expense associated with discontinued operations was $18 million and $96 million for the nine months ended December 31, 2018 and December 31, 2017, respectively.
