YES, you can apply for Tozo without worries!
The State Secretary of Justice and Security has communicated to Parliament that claiming a Tozo benefit will not have any negative consequences for holders of residence permits who are required to have a certain income-earning capacity (such as holders of residence permits with the purpose “arbeid als zelfstandige”, i.e. work in self-employment).
To apply, visit the website of your municipality (gemeente). For legal details see the blog of Franssen Advocaten: http://franssenadvocaten.nl/english/can-residence-permit-holders-apply-for-the-coronavirus-support-for-zzpers/.
