Travel Reimbursement Policy & Procedures

DIMACS must adhere to travel reimbursement policies defined by our funding agencies and by Rutgers University; therefore, we are unable to reimburse travel arrangements that do not comply with these policies.  Please carefully review the "Important Policies Affecting Your Reimbursement" outlined below before incurring any expenses that you would like to have reimbursed.

If you have any questions, please contact the DIMACS Financial Assistant before booking your travel.

We ask that you submit your reimbursement as soon as possible, preferably within 2 weeks of your return. We may be unable to process reimbursements requested more than 6 weeks after the conclusion of travel, so please be aware of timing.

Submitting Your Reimbursement Request

In order to claim travel expenses, you must complete and sign the DIMACS Travel Reimbursement Form.

The DIMACS Reimbursement Form should be emailed to the DIMACS Financial Assistant. Please include a copy of all itemized receipts for expenses that you are claiming for reimbursement.

After we receive your reimbursement form and receipts, the DIMACS Financial Assistant will be in touch with next steps. Your reimbursement will be processed though the Rutgers payment system, and a check will be sent to the address that you have provided.

Important Policies Affecting Your Reimbursement

Fly America Compliance: Air travel must comply with the Fly America Act. DIMACS is only able to reimburse travel that complies with the Fly America Act. In many cases this requires travel on US-flag carriers, regardless of cost. US-flag carriers are sometimes “code shared” with an international carrier for international flights. In cases where a US carrier is required, it is permissible to take code-shared flights if (and only if) your ticket is booked through the US carrier. Our funding agencies do not allow exceptions for convenience, preference, or availability of lower fares. Certain exceptions to the requirement to fly on a US carrier are granted through international “Open Skies Agreements.” Most notably, an Open Skies agreement between the US and the countries of the European Union allows for reimbursement of flights on EU carriers when they are between the US and an EU country.

Reasonable Cost Policy: All travel is subject to funding agency requirements for “reasonable costs”. We interpret these to be economy class airfares, standard airport limousines or taxis, and similar transport. Only coach-class travel by air or train can be reimbursed. (We, therefore, cannot reimburse travel on Amtrak Acela.)

Combined Travel Policy: Travelers who combine DIMACS travel with other trips cannot be reimbursed for more than the cost of a round-trip, economy class, standard flight (to the DIMACS event from their home location). If your trip includes additional destinations, you will need to obtain documentation (such as a printed priced itinerary from a travel agent or on-line travel service) indicating what the total cost of a direct round-trip flight would be, and submit this along with receipts for your actual itinerary. We suggest that you contact the DIMACS Financial Assistant in advance to assure that you are able to receive the maximum appropriate reimbursement.

Proof of payment - Hotel: For hotel reimbursement, you must provide an itemized bill and a receipt showing a balance of $0.00. Personal charges such as telephone calls, pay-per-view, laundry services, etc. are not reimbursable.

Rental Cars: Use of rental cars is generally discouraged, unless there is a compelling business justification and the cost is less than other alternatives. For example, we cannot typically reimburse rental cars from Newark airport to the Rutgers campus. If you are considering renting a car, please speak with the DIMACS Financial Assistant in advance. Full documentation is required in order to obtain reimbursement.

Proof of Payment - Local expenses: Other local expenses such meals, taxis (including Uber, etc), parking, etc. must be documented with receipts. DIMACS reimburses only your own meals, and only meals not otherwise provided. Where possible, you should document restaurant meals with itemized receipts containing only your personal expenses. Meal receipts showing charges for additional diners should be itemized, and you should specifically identify your own meal. If your receipt includes meals of others, then you must list their names on the receipt.

Alcohol: Alcoholic beverages are never reimbursable.

DIMACS Registration Fees: DIMACS event registration fees are not reimbursable for any reason. The registration fees collected at DIMACS events are used to cover catering costs, material costs, and staff support.

After We Receive Your Reimbursement Request

Once we receive your reimbursement request, the DIMACS Financial Assistant will process it, get approvals within DIMACS, and send it to Rutgers Accounts Payable where it will go through further review and approval. If there are any issues in the documentation of expenses, we will contact you and work with you to see to determine whether sufficient documentation can be obtained.

If you are not on Rutgers payroll, Accounts Payable will issue a check once your reimbursement is approved. The check will be mailed to the address you provide on the reimbursement form. The entire process usually takes approximately 8 weeks, but it can take longer. Please note that funds cannot be electronically wired to a bank account, personal or otherwise. You will have 90 days to cash your check before it becomes invalid. Approved reimbursements to Rutgers employees will be paid in an upcoming paycheck rather than as a separate check.

If you have any questions regarding the reimbursement process or would like an update on the status of your reimbursement, please do not hesitate to contact the Financial Assistant at
