To provide that reimbursement of Members of Congress by the House of Representatives for expenses incurred in connection with official duties are not subject to tax.

HR 5880 makes reimbursements to Members of Congress (including delegates and resident commissioners) for official duty expenses tax-free. Specifically, it excludes from gross income any reimbursement paid from a Member's Representational Allowance (MRA) for expenses incurred while performing official duties, as defined in the House's Members' Congressional Handbook. This change applies only to MRA reimbursements for legitimate official expenses, not other income, and ensures these amounts are not counted toward taxable income or used to calculate other tax benefits under the Internal Revenue Code.
