This is actually dependent on your genetic profile, more specifically on the ADORA2 gene. Depending on the variation of the ADORA2 gene you poses, caffeine is more or less likely to affect your sleep. Those with the sensitive variation of the ADORA2 gene should avoid consuming caffeine in the afternoon, and no later than 3pm. Those with the less sensitive versions of the ADORA2 gene can consume coffee (caffeine) much closer to bed time without experiencing any negative side effects. Tolerance can also play a role. This means the more regularly you consume caffeine before bed time, the less likely it is to effect your sleep and vice versa.
