TCJA suspended miscellaneous itemized deductions, including unreimbursed employee expenses, for 2018–2025. OBBBA §70110 made that permanent. The remaining exceptions don't fit a staff or agency nurse: Armed Forces reservists, fee-basis officials, qualifying performing artists, impairment-related work expenses, and eligible K-12 educators. (Notice 2026-10)
What it means for you
W-2 mileage, scrubs, license renewals, CEUs, and similar costs are not deductible.
Keep logging them anyway: they're evidence for reimbursement requests.
Reimbursements under an accountable plan are tax-free to you.
If the same cost relates to your 1099 work, such as an LNC course or a license used for consulting, log it under the 1099 job instead.
What to do instead
Ask your employer or agency to reimburse these under its accountable plan, since reimbursements are tax-free.
Also check whether it offers §127 educational assistance: up to $5,250/yr tax-free, which OBBBA §70412 made permanent and which can include student-loan principal and interest payments. The amount is indexed after 2026. (Rev. Proc. 2025-32 §2.09)
