The COMPASS Experiment at CERN is celebrating this year the 20th anniversary of its' activity after the
approval in 1997 and in this presentation an overview of the recent results on the Transverse Momentum Dependent (TMD)
effects in semi-inclusive DIS reactions will be given.
TMD effects have been investigated both in unpolarised SIDIS by measuring the dependence of charged hadrons
multiplicities from the transverse momentum PhT and by measuring the azimuthal cosϕ and cos2ϕ
modulations related to Cahn and to the Boer-Mulders TMD PDF, in transversely polarised SIDIS by measuring the Collins,
the Sivers and all the others transverse spin dependent asymmetries, and recently also in the first ever polarized
Drell-Yan experiment, started in 2015. Future plans for the investigations of TMDs both in COMPASS will be also briefly
presented.
