The COMPASS Experiment at CERN is celebrating this year the $20^{th}$ 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 $P_{hT}$ and by measuring the azimuthal $\cos \phi$ and $\cos 2\phi$
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.
