IRS Material: Safe Deposit

Safe deposit box rent. You can deduct rent you pay for a safe deposit box if you use the box to store taxable income-
producing stocks, bonds, or investment-related papers and documents. If you use the box to store taxable securities and
tax-exempt securities or personal items, you can deduct only a part of the rent. See Tax-exempt income later, under
Nondeductible Expenses, to figure what part you can deduct.
