Изучите следующую ситуацию:

Предложение 'I'll telephone y'all when I become domicile' состоит из двух частей:

и

главная часть:
часть с when :

'when I get home'

Время в предложении - будущее ('tomorrow'), но мы используем настоящее время (I get) в части предложения с when.

Мы не используем will в части предложения с when.

Еще немного примеров:

Вы также можете использовать present perfect (accept washed) после when / subsequently / until / every bit soon as:

  (= Сначала я позвоню Кате, и только потом мы можем начать обедать.)

Не используйте present perfect, если два действия происходят в одно и то же время:

Часто можно использовать как present uncomplicated, так и nowadays perfect:
