NASA Domestic Travel Per Diem

Per Diem on the Last Day of Travel

For NASA domestic travel, the per diem allowance on the final day of the trip—the day the traveler returns to the permanent duty station (PDS), home, or another permitted point—is 75% of the meals and incidental expenses (M&IE) rate.

Rental Car Liability

When booking a rental car, remember that the government is responsible only for rental car costs incurred during official travel. If a traveler takes annual leave in conjunction with official travel and keeps the rental car during annual leave, the traveler is responsible for the portion of the rental cost attributable to annual leave. See 41 CFR 301-10.453.

What is my liability for unauthorized use of a rental car obtained with government funds?

Any additional costs resulting from unauthorized use of a commercial rental car for purposes other than official travel are the responsibility of the traveler.

Duty-Free and State Tax Information

Before traveling, review the GSA SmartPay state tax information page. Select the applicable state or U.S. region to check exemption status and download the appropriate form, if needed.

Reduced Per Diem for Extended TDY (ETDY)

NASA’s standard reduced per diem rate for ETDY travel is 65% under current policy, as defined in NASA Procedural Requirement (NPR) 9750.1-3.1.2.

In accordance with 41 CFR 301-11.200, an ETDY authorization may include additional reasonable reductions to the standard rate or limits on approved accommodations when significant cost savings can be determined in advance without affecting the mission. For example, if lodging is available at 50% of the per diem rate, the ETDY authorization must be adjusted to approve the lower rate.

The reduced per diem rate begins on the first day of travel, regardless of the mode of transportation, except as stated in section 3.1.3. Because allowances are covered by a reduced daily rate, NASA permits employees to receive a per diem rate of up to 65% to reasonably cover the cost of a furnished one-bedroom apartment.

If ETDY lasts longer than 90 days, travelers should consider long-term accommodations first. Long-term accommodations are available at locations listed in the GSA schedule. If long-term lodging is not selected, an appropriate reason must be provided. Visit the GSA website for more information.

For information about allowable ETDY expenses included in the reduced per diem amount, review the applicable ETDY expense guidance.

GSA Long-Term Accommodations: Schedule 48

GSA Schedule 48 is designed for lodging needs of 30 days or more. The program provides temporary or permanent relocation housing, including apartment- or condominium-style properties with the amenities of a regular home. The linked page includes a current list of vendors.

Many of these accommodations support NASA ETDY travelers at a 65% reduced per diem rate and permit the use of government charge cards.
