The rule, in three lines

Creo que es tarde — you are asserting it, so indicative. No creo que sea tarde — you are denying it, so subjunctive. The same flip happens with pensar, parecer, es verdad que and está claro que: affirmative takes the indicative, negative takes the subjunctive.

The usual slip. Applying “subjunctive after que” as a blanket rule, and saying creo que sea.

Why it catches you out. English marks doubt with a modal or with intonation — “I don't think it IS” stays in the indicative — so there is no signal in your language to copy. Spanish marks it in the verb itself, and the switch is mechanical: put a “no” in front of “creo” and the other verb has to move.
