Income Taxes | Income Taxes The effective tax rate was 33.4% and 33.1% for the three and six months ended March 31, 2017, respectively, compared to 34.5% and 33.2% for the three and six months ended March 31, 2016, respectively. At March 31, 2017, the Company had $17.5 million of unrecognized tax benefits that, if recognized, would affect the effective tax rate. It is anticipated that the Company’s existing liabilities for unrecognized tax benefits will change within the next twelve months due to audit settlements or the expiration of statutes of limitations. The Company does not expect these changes to be material to the consolidated financial statements. The Company recognizes interest and, if applicable, penalties for any uncertain tax positions as a component of income tax expense. The Company and its subsidiaries are subject to U.S. federal income tax as well as the income tax of multiple state and foreign jurisdictions. The Company has concluded all U.S. federal income tax matters for fiscal years through September 30, 2012. The Company is currently under audit by various states for fiscal years 2012 through 2015. Major jurisdictions where there are wholly owned subsidiaries of F5 Networks, Inc. which require income tax filings include the United Kingdom, Japan, Singapore and Australia. The earliest periods open for review by local taxing authorities are fiscal years 2015 for the United Kingdom, 2011 for Japan, 2012 for Singapore, and 2013 for Australia. Within the next four fiscal quarters, the statute of limitations will begin to close on the fiscal year 2013 federal income tax return, and fiscal years 2012 and 2013 state income tax returns. |
