These compounds give different ions in aqueous solution. This can be tested by using AgNO3 solution and BaCl2

[Co(NH3)5Cl]SO4(aq) + BaCl2(aq) → BaSO4(ppt)

[Co(NH3)5Cl]SO4(aq) + AgNO3(aq) → no reaction

[Co(NH3)5(SO4)]Cl(aq) + BaCl2(aq) → no reaction

[Co(NH3)5(SO4)]Cl(aq) + AgNO3(aq) → AgCl(ppt)

Hence they give different precipitates with different solutions. Thus they are ionisation isomers.
