Should persons register self-employment when selling property not subject to registration

If the sale of property not subject to registration is of occasional nature (e.g. the sale of household appliances purchased for personal use, the sale of used clothing), then there is no obligation to register self-employment. 

If the sale of property not subject to registration has elements of continuity or seeking economic gain, then the obligation to register self-employment arises. To determine whether sales meet the above elements of self-employment, the following are taken into account: continuity, repetition, intention to enter into more commercial transactions of a similar nature, motivation to generate income or other economic benefits.
