can I declare condo fees as an expense if I work from home

Are you a W-2 employee?

Sorry---W-2 employees cannot deduct job-related expenses on a federal return.  Job-related expenses were eliminated as a federal deduction for W-2 employees by the tax laws that changed for 2018 and beyond.  Your state tax laws might be different in AL, AR, CA, HI, MN, NY or PA.

If you live in a state that lets you deduct job-related expenses, the information will flow from your federal return  to the state return, so enter it in Federal>Deductions and Credits>Employment Expenses>Job-Related Expenses

If you are a employee who receives a W-2 then none of your employee business expenses are deductible on a federal tax return due to the tax code changes in effect for tax years 2018 thru 2025.
