Travel and Business Expense Reimbursement

Any Columbia University student, employee or visitor can be reimbursed for valid business and research related expenses. Prior-approval must be obtained from the professor or department that is providing funding.

Please use the below links for general guidelines, forms, questions and online submission. You may also submit documentation in person to our Financial Assistants in room 450 Computer Science Building.

All CS expense reports and receipts should be sent to reimbursement@cs.columbia.edu

The payee is expected to obtain itemized receipts for all expenses $50 and above, and must retain all documentation until expenses have been reimbursed. Proof of payment must be submitted for all expenses, regardless of amount, in order to ensure submissions are in compliance with Accounts Payable review and audit procedures. 

Itemized receipts are strictly required for the following travel expenses regardless of amount:

  • Roundtrip travel to and from destination (Air/Rail/Bus Tickets)
  • Hotel/lodging (hotel folio/Airbnb etc.)
  • Car rental

Receipts

A receipt may take many forms (i.e. cash register receipt, copy of an order form, web receipt or confirmation). A complete receipt must identify: 

  • Date of purchase
  • Vendor name
  • Itemized list and unit price of the purchased items
  • Total amount

For other expenses, if you were not able to obtain a receipt, lost the receipt, or the receipt is incomplete (i.e. not itemized), you may create a Missing Receipt Declaration (Affidavit) for the expense under Manage Receipts.

To learn how to add a Missing Receipt Declaration for those Expense Item missing required receipts, view and download the following job aid:

Proof of Payment

The payee is also expected to obtain proof of payment for all expenses. Proof of payment is usually included in the receipt with a notation of:

  • “Cash tendered”
  • “Paid”
  • A zero balance due
  • Debit/Credit card payment (card type, last four digits of card and/or signature)

If no proof of payment is available in this form (i.e. missing or incomplete receipt), a debit or credit card statement may be provided. You may black out any private or unrelated information. If an expense was paid in cash, add a comment stating it was paid in cash.

Expenses in Foreign Currency

Users can specify the currency when they are adding the details of the expense. Once the amount is entered in foreign currency and the currency type is updated, the fields displaying the conversion rate and the amount in U.S. Dollars will automatically appear. The conversion rate automatically updates based on the transaction date.

Are my reimbursement expenses taxable?

No, you will not be charged tax. Columbia University requires everyone to submit a W-8 or W-9 form along with their first reimbursement. This information is only used to process your payment. However, reimbursements submitted past 120 days from the date of the last expense are considered taxable income and may be taxed. Any expense a year old will not be reimbursed.

Which form, W-8 or W-9?

Personal Vehicle

Instead of a car rental, you may want to use your own personal vehicle. Reimbursement rates are based on total miles traveled and you cannot be reimbursed the cost of gas when using this method. The personal vehicle mileage rate changes each year, hovering around $.575/mile. For the current rate, please check with our Financial Assistants. In addition:

  • Provide an online printed map indicating the total mileage between your home and conference/trip destination
  • Place the total number of miles on the first page of the reimbursement in the “Personal Vehicle Mileage” section
  • Write the total amount as a new expense number with the business purpose, “Personal Vehicle Mileage”
