The mem­ber-soci­eties of the IARU pay dues to the region­al IARU orga­ni­za­tion to which they belong. The region­al orga­ni­za­tions expend their income in accor­dance with the bud­gets adopt­ed by the mem­ber-soci­eties at region­al conferences.

The region­al orga­ni­za­tions con­tribute 10% of their dues income to the Inter­na­tion­al Sec­re­tari­at to defray a por­tion of the expens­es incurred by the Inter­na­tion­al Sec­re­tari­at that are above and beyond its Con­sti­tu­tion­al oblig­a­tion. These expens­es are relat­ed pri­mar­i­ly to rep­re­sent­ing the ama­teur and ama­teur-satel­lite ser­vices at the ITU and oth­er inter­na­tion­al organizations.

The income of mem­ber-soci­eties, includ­ing the Inter­na­tion­al Sec­re­tari­at, comes from the dues paid by the indi­vid­ual mem­bers of the mem­ber-soci­eties. When a radio ama­teur or friend of ama­teur radio joins his or her nation­al IARU mem­ber-soci­ety, a por­tion of the dues helps to off­set the expens­es of inter­na­tion­al representation.
