The only inflectional feature of adverbs is degree. There are three tags for adverbs:

Positive degree: FST frumstig
Comparative degree: MST miðstig
Superlative degree: EST efsta stig
Example: vel, betur, best ‘well, better, best’
vel;ao_FST adverb, positive degree
betur;ao_MST adverb, comparative degree
best;ao_EST adverb, superlative degree

The Icelandic abbreviation for adverb is ao. It is included in the tag for the word class (unlike most other word classes).
