Passive individual members

You would like to support the great commitment of ISIS, but are not (anymore) actively involved in tax law yourself?
As a passive member, you make a valuable contribution
to the activities of ISIS for an economical, fair
and comprehensible tax system as well as for a scientifically sound and practice-oriented further education in tax law.

The annual membership fee for individual members is CHF 110 (incl. VAT).

Honorary members

Honor to whom honor is due. In the case of special services to our Institute or exceptional achievements in tax law, the General Assembly of ISIS may confer honorary membership on individuals. Honorary members do not pay a membership fee.
