Ask your employer if the reimbursement for the furniture will be added to your W-2, and whether they will want the furniture if you leave the job. As for claiming the expense for buying the furniture on your tax return you cannot do that. Job-related expenses are not deductible on a federal tax return for W-2 employees.
