The Complete Guide to Joint Travel Regulations for TDY Travel
The Joint Travel Regulations govern every aspect of official travel for military members and Department of Defense civilian employees. Understanding these regulations ensures you receive proper entitlements while avoiding violations that could result in repayment demands or disciplinary action.
What the JTR Covers
The Joint Travel Regulations is a comprehensive document that establishes rules for transportation, lodging, per diem, and other travel entitlements. It applies to all uniformed service members, DoD civilian employees, and in some cases, their dependents. The regulations are updated regularly, so relying on outdated guidance can lead to compliance issues.
Key areas covered include authorization and approval requirements, transportation modes and classes of service, lodging and meals reimbursement, special circumstances like travel with dependents, and the documentation required for reimbursement claims.
Authorization Before Travel
One fundamental JTR principle is that authorization must occur before travel begins. Your travel orders constitute this authorization, specifying what expenses are approved and any limitations that apply. Traveling without proper orders or exceeding your authorization can result in personal liability for expenses.
The authorization should include your travel dates, destination, purpose, lodging and transportation modes approved, and any special authorizations like rental cars or excess baggage. Review your orders carefully before departing and contact your authorizing official if anything seems incorrect or missing.
Transportation Entitlements
The JTR establishes a hierarchy for transportation selection. Government or contract transportation comes first when available. Commercial transportation is authorized when government options are not practical. The regulations specify economy class for air travel, with premium class requiring specific justifications and approvals.
For ground transportation, the JTR considers cost comparisons between driving a privately owned vehicle, rental cars, and other options. The regulations include formulas for determining when each option is most advantageous to the government while being fair to the traveler.
Lodging Requirements
The JTR requires travelers to use government quarters when available and adequate before seeking commercial lodging. This requirement ensures efficient use of government resources. When commercial lodging is authorized, the regulations cap reimbursement at locality per diem rates unless actual expense allowance is approved.
Adequacy standards for government quarters have specific definitions in the regulations. Quarters must meet minimum standards for safety, cleanliness, and essential amenities. If government quarters do not meet these standards, you may obtain a certificate of non-availability and stay commercially.
Per Diem Calculations
Per diem consists of lodging plus meals and incidental expenses. The JTR specifies how per diem is calculated for different situations. Travel days, the first and last day of travel, typically receive 75 percent of the M&IE rate. Full TDY days receive 100 percent. When government meals are provided, the per diem is reduced accordingly.
Understanding proportional meal deductions is important when attending conferences or training where some meals are included. The regulations specify exact deduction amounts for breakfast, lunch, and dinner that vary by locality per diem rate.
Special Circumstances
The JTR addresses numerous special circumstances that may apply to your travel. Long-term TDY over 30 days has different lodging options including temporary quarters subsistence allowance. Travel with dependents for certain assignments has specific entitlements and limitations. Emergency leave during TDY has rules for transportation and per diem continuation.
International travel introduces additional considerations including foreign currency conversions, country-specific safety and security requirements, and overseas per diem rates that differ from domestic calculations.
Documentation and Record Keeping
The JTR requires specific documentation for different expense types. Lodging always requires receipts regardless of amount. Other expenses require receipts when exceeding $75. However, maintaining receipts for all expenses is wise practice even when not strictly required.
Your travel voucher must accurately reflect actual expenses incurred. Knowingly filing a false voucher is fraud with serious consequences including criminal prosecution. When in doubt about proper claims, consult with your finance office before submitting.
Staying Current
The Defense Travel Management Office maintains the current JTR and publishes updates regularly. Bookmark their website and review updates that affect your travel situation. Your local finance office and Defense Travel Administrator can also provide guidance on regulatory changes and proper procedures.
Understanding the JTR empowers you to maximize legitimate entitlements while maintaining compliance. This knowledge serves you throughout your career as TDY travel is an ongoing reality for most military members and government employees.
