Sumario:The COMPASS Experiment at CERN is celebrating this year the $20^{th}$ anniversary of its' activity after theapproval 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 hadronsmultiplicities 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 polarizedDrell-Yan experiment, started in 2015. Future plans for the investigations of TMDs both in COMPASS will be also brieflypresented.
