We develop the Ginzburg--Landau theory of the upper critical field in the basal plane of a tetragonal multiband metal in two-component superconducting state. It is shown that typical for the two-component superconducting state, the upper critical field basal plane anisotropy and the phase transition splitting still exist in a multiband case. However, the value of anisotropy can be effectively smaller than that in the single band case. The results are discussed in the application to the superconducting Sr2RuO4.
