What is Perfect Tense in German?

Perfect tense in German is formed with an auxiliary verb (haben or sein) plus the past participle of the main verb. Most verbs use haben, but sein is used for motion and state-change verbs — this distinction is key to mastering German past tense.

Short answer

Perfect tense combines haben or sein + past participle. Haben is default; use sein for motion/change verbs (gehen, fahren, werden) — e.g., Ich habe gegessen (I have eaten) vs. Ich bin gegangen (I have gone).

Haben vs Sein in Perfect Tense

Haben (Most verbs)

•Regular actions
•Eating, drinking, working
•ich habe gegessen
•du hast geschrieben

Sein (Motion & state change)
