13. INCOME TAXES

There has historically been no federal or state provision for income taxes because the Company has incurred operating losses and maintains a full valuation allowance against its net deferred tax assets and liabilities in the United States. For the three months ended March 31, 2023 and 2022, the Company recognized no provision for income taxes in the United States. The foreign provision for income taxes was immaterial for the three months ended March 31, 2023 and 2022.

​

Utilization of net operating loss carryforwards, tax credits and other attributes may be subject to future annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions.
