•Objective: This study assesses changes in parents’ divisions of housework and childcare over the course of the COVID-19 pandemic. •Background: Assessing the long-term consequences of the COVID-19 pandemic for gender equality requires understanding how and why labor arrangements shifted as the pandemic progressed. Yet, we know little about US parents’ domestic arrangements beyond the early days of the COVID-19 pandemic or how simultaneous changes in men’s and women’s employment, earnings, telework, gender ideologies, and access to care supports may have altered domestic labor arrangements.•Method: This study assesses change in parents’ domestic labor using fixed-effects regression on data from a longitudinal panel of 700 different-sex partnered US parents collected at three time points: March 2020, April 2020, and November 2020.•Results: Partnered parents’ divisions of housework and childcare became more equal in the early days of the pandemic, but reverted toward pre-pandemic levels by the fall of 2020. Changes in parents’ divisions of domestic labor were largely driven by changes in parents’ labor force conditions, and especially by fathers’ labor force conditions. Decreases in fathers’ labor force participation and increases in telecommuting in April portended increases in partnered fathers’ shares of domestic tasks. As fathers increased time in paid work and returned to in-person work by fall, their shares of domestic labor fell.•Conclusion: Overall, results suggest that promoting full-time employment among mothers and greater time at home for fathers are key in facilitating a more equal division of domestic labor within families post-pandemic.
