The anomalous dimuon charge asymmetry reported by the D0 Collaboration may be due to the tree-level exchange of some spin-0 particles that mediate CP violation in B{sub s}-B{sub s} meson mixing. We show that, for a range of couplings and masses, the heavy neutral states in a two-Higgs doublet model can generate a large charge asymmetry. This range is natural in ''uplifted supersymmetry'' and may enhance the B{sup -{yields}{tau}{nu}} and B{sub s{yields}{mu}}{sup +{mu}-} decay rates. However, we point out that on general grounds the reported central value of the charge asymmetry requires new physics not only in B{sub s}-B{sub s} mixing but also in {Delta}B=1 transitions or in B{sub d}-B{sub d} mixing.
