Lucy acquired a building for use in her trade or business in 2010 for $2,000,000.

Through the end of 2020, she had taken total depreciation expense on the building of $700,000.

Lucy sold the building on 12/31/20 for $2,500,000 (this is the only Section 1231 asset she sold this year).

Assuming her preferential tax rate is 20%, what is Lucy's total tax liability associated with the sale of the building?
