We start by presenting the current status of a complex flavour conserving two-Higgs doublet model. We will focus on some very interesting scenarios where unexpectedly the light Higgs couplings to leptons and to b-quarks can have a large pseudoscalar component with a vanishing scalar component. Predictions for the allowed parameter space at end of the next run with a total collected luminosity of 300fb−1 and 3000fb−1 are also discussed. These scenarios are not excluded by present data and most probably will survive the next LHC run. However, a measurement of the mixing angle ϕτ, between the scalar and pseudoscalar component of the 125 GeV Higgs, in the decay h→τ+τ− will be able to probe many of these scenarios, even with low luminosity. Similarly, a measurement of ϕt in the vertex tˉth could help to constrain the low tanβ region in the Type I model.
