UEFA's Club Financial Control Body has fined Manchester United €300,000 (£256,744) for a "minor breakeven deficit" under its Financial Fair Play rules.
The CFCB found United did not meet their target to approach breakeven on football-related business, including player transfers, wages and social taxes.
A United statement read: "While disappointed by the outcome, Manchester United accepts this fine for what UEFA acknowledges to be a minor technical breach of its previous Financial Fair Play rules.
"This reflected a change in the way that UEFA adjusted for Covid-19 losses during the 2022 reporting period, which allowed us to recognise only €15m (£12.8m) of the €281m (£240.5m) of revenues lost due to the pandemic within the FFP calculation.
"Post-pandemic, the clubs' revenues have recovered strongly and are forecast to reach a record level in the current financial year.
"The club continues to support the enforcement of rules to promote financial fair play and sustainability across domestic and European football."
United are understood to be disappointed with what they see as UEFA's lack of flexibility over accounting for losses during Covid-impacted seasons but accept they did commit the breach.
