Income Taxes Income Taxes
We estimate our annual effective income tax rate to be 8% for fiscal 2023, which is lower than the U.S. federal statutory rate, primarily due to (i) a significant portion of our income qualifying for preferential treatment as foreign-derived intangible income (FDII) at a 13% effective tax rate, which includes certain benefits discussed below from the new requirement to capitalize research and development expenditures for federal income tax purposes, (ii) benefits from our federal research and development tax credit and (iii) benefits related to foreign currency gains on a noncurrent receivable related to our refund claim of Korean withholding tax. Our effective tax rate of 10% for the second quarter of fiscal 2023 was higher than our estimated annual effective tax rate of 8% primarily due to foreign currency gains realized in the first quarter of fiscal 2023 on a noncurrent receivable related to our refund claim of Korean withholding tax.
Beginning in fiscal 2023, for federal income tax purposes, we are required to capitalize and amortize domestic research and development expenditures over five years and foreign research and development expenditures over fifteen years (such expenditures were previously deducted as incurred). Our cash flows from operations will be adversely affected due to significantly higher cash tax payments. However, since the resulting deferred tax asset is established at the statutory rate of 21% (rather than the effective tax rate of 13% to 16% after considering the FDII deduction), capitalization favorably affects our provision for income taxes and results of operations. The adverse cash flow impact and favorable tax provision impact will diminish in future years as capitalized research and development expenditures continue to amortize.
Income taxes payable (recorded in other current liabilities) were $1.3 billion and $634 million at March 26, 2023 and September 25, 2022, respectively. This increase was primarily due to the recent announcement (IR-2023-33) by the Internal Revenue Service (IRS), which postponed our remaining current year U.S. federal income tax-payment deadlines until October 2023.
