At December 31, 2021, we had approximately $17.2 billion of gross federal net operating losses (NOLs) and $3.0 billion of other carryforwards available to reduce future federal taxable income, of which $6.9 billion will expire beginning in 2024 if unused and $13.3 billion can be carried forward indefinitely. We also had approximately $6.0 billion of NOL carryforwards to reduce future state taxable income at December 31, 2021, which will expire in taxable years 2021 through 2041 if unused.
Our ability to use our NOLs and other carryforwards depends on the amount of taxable income generated in future periods. We provide a valuation allowance for our deferred tax assets, which include our NOLs, when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our assessment of future profitability, including conditions which are beyond our control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. We presently have a $34 million valuation allowance on certain net deferred tax assets related to state NOL carryforwards. There can be no assurance that an additional valuation allowance on our net deferred tax assets will not be required. Such valuation allowance could be material.
Our ability to deduct our NOL carryforwards and to utilize certain other available tax attributes can be substantially constrained under the general annual limitation rules of Section 382 where an “ownership change” has occurred. Substantially all of our remaining federal NOL carryforwards attributable to US Airways Group are subject to limitation under Section 382; however, our ability to utilize such NOL carryforwards is not anticipated to be effectively constrained as a result of such limitation. Similar limitations may apply for state income tax purposes. Our ability to utilize any new NOL carryforwards arising after the ownership changes is not affected by the annual limitation rules imposed by Section 382 unless another ownership change occurs. Under the Section 382 limitation, cumulative stock ownership changes among material stockholders exceeding 50% during a rolling three-year period can potentially limit our future use of NOLs and tax credits.
In 2021, we recorded an income tax benefit of $555 million, with an effective rate of approximately 22%, which was substantially non-cash. Substantially all of our loss before income taxes is attributable to the United States.
We file our tax returns as prescribed by the tax laws of the jurisdictions in which we operate. Our 2018 through 2020 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination and we are under examination, in administrative appeals, or engaged in tax litigation in certain jurisdictions. We believe that the effect of any assessments will not be material to our consolidated financial statements.
The amount of, and changes to, our uncertain tax positions were not material in any of the years presented. We accrue interest and penalties related to unrecognized tax benefits in interest expense and operating expense, respectively.
