I'm assuming you're talking about tropical hibiscus (Hibiscus rosa-sinensis), which need at least 4-5 hours of direct sunlight to bloom.
A few questions:
How long have you owned it?
Is it root bound?
Where do you have it in the summer?
How much and what kind of fertilizer do you use?
Since it's not blooming now, it may not bloom for you until the spring. In the mean time, there are a few things you can do to give it a good start then.
Once you've answered the questions I (and others here) will have a better idea of what advise you can use.

I've owned this hibiscus for a year.

It did appear rootbound at the end of this summer and I have transplanted it into a larger pot where it promptly died off this fall and is currently regenerating.

I use 24-8-16 All Purpose fertilizer once every 2 weeks.

During the summer months it is in direct sunlight for at least four hours a day if not more.

I hope I've answered all of your questions here as I would really love to see this hibiscus bloom.

That's a good sign that it's getting new leaves and it's not surprising that it lost them when you repotted. They do that sometimes, not a big deal.
In the spring and summer, use a fertilizer with equal numbers (not a bigger first number) or one meant for blooming plants.
Here's a link to a site that I've always found to be helpful.
It'll help guide you through winter care and getting the plant to BLOOM!
Good luck!
