Can I claim my professional license renewal fee if I was not employed in that field? I have to pay it annually weather I have a job or not. and i was only employed for 1 month.

To be deductible, your expenses must be for education that either maintains or improves your job skills, or is required by your employer or by law to keep your salary, status or job.

Expenses to learn a new trade or job or to qualify for anew career aren't deductible

So, you must be actually employed to claim your professional license renewal.
