The Company presents the impact of uncertain tax positions in the effective tax rate reconciliation on an aggregate worldwide basis. This uncertain tax position line amounts includes the positions related to federal and state research and development (“R&D”) credits as well as transfer pricing matters. Accordingly, amounts related to uncertain tax positions are included in the “Changes in unrecognized tax benefits” line and are not allocated to specific jurisdictions, such as federal, state, or foreign taxes. As a result, certain items related to state or foreign tax matters may be reflected within this line rather than within the respective jurisdictional categories in the rate reconciliation. Greater than 50% of the state tax benefit was primarily due to California R&D credits. As previously disclosed for the periods ended January 31, 2025 and 2024, prior to the adoption of ASU 2023-09, the effective income tax rate differed from the statutory federal income tax rate as follows:
|  |  | Year Ended January 31,
|  |  | 2025 |  | 2024
Tax at federal statutory rate |  |  | 21.0 | % |  | 21.0 | %
Stock-based compensation |  |  | (7.6 | %) |  | (2.6 | %)
Change in valuation allowance |  |  | (13.4 | %) |  | (19.5 | %)
Research and development tax credits |  |  | 0.4 | % |  | 0.6 | %
Other |  |  | (2.0) | % |  | 0.6 | %
Effective tax rate |  |  | (1.6) | % |  | 0.1 | %
