Here are some good sources for finding paying markets:
15 Magazines That Pay $500 or More
Many of these journals specialize in niche markets, which means they have a loyal readership. If you happen to have expertise or a background that would appeal to their audiences, these magazines will be happy to read your pitch. Quite a few accept poetry.
These magazines represent everything from speculative fiction, to poetry, to gardening. Payments range from $1.25 to $1,000. You will find a home for your work in this list. (This list is continually updated.)
Going through the Poets & Writers database, I found 36 magazines that pay their contributors. This is a nice selection with something for everyone.
13 Paying Markets for Personal Essays
Like the short story, personal essays are structured, have a theme, and usually involve a moral or message of some kind. Some literary journals and niche magazines are willing to pay substantially for these essays, so devoting a few hours to writing one is worth your consideration.
18 Paying Markets for Humor
If you have a sense of humor, why not use it to make some money? There are ample economic opportunities for people who can see the lighter side of life, or skewer the darker side with a well-aimed quip. These publications will be more than happy to pay you to make their readers laugh.
If you write science fiction, fantasy, or horror you will want to pore over this list. I have included pay ranges as well as whether they accept simultaneous submissions and/or reprints.
Most magazines do not accept reprints, but some (surprisingly) do. I have indicated which markets are currently paying writers.
