Understanding FY2026 GSA Per Diem Rates for Atlanta
What GSA Per Diem Rates Cover
The General Services Administration sets maximum reimbursement rates for federal employees traveling domestically, and these rates serve as a standard benchmark for private sector travel policies. Per diem covers two categories:
- Lodging: The maximum nightly rate a traveler can be reimbursed for hotel accommodations (actual cost up to the cap, not a flat allowance)
- Meals and Incidental Expenses (M&IE): A flat daily allowance covering breakfast, lunch, dinner, tips, and small transportation costs
Atlanta qualifies as a designated locality with rates above the standard CONUS baseline. The GSA reviews lodging costs annually and adjusts rates based on local hotel market data.
Atlanta's Seasonal Rate Structure
Unlike cities with flat year-round rates, Atlanta has two lodging tiers within FY2026:
Peak Season (January - March 2026):
- Lodging per Night: $197
- M&IE per Day: $86
- Total per Day: $283
Regular Season (October - December 2025, April - September 2026):
- Lodging per Night: $182
- M&IE per Day: $86
- Total per Day: $268
The peak season premium of $15/night (8.2% increase) coincides with Atlanta's convention season and milder winter weather. The M&IE rate stays constant regardless of travel dates.
M&IE Breakdown by Meal Component
The $86 daily M&IE allowance breaks down into specific allocations:
- Breakfast: $22 (25.6% of total)
- Lunch: $23 (26.7% of total)
- Dinner: $36 (41.9% of total)
- Incidentals: $5 (5.8% of total)
This breakdown matters when meals are provided (conference lunch, client dinner) and the traveler must reduce their daily allowance accordingly. The incidentals portion covers tips to porters, baggage handlers, and similar service providers.
Applying the 75% Travel Day Rule
First and Last Day Calculations
Federal travel regulations require a reduced M&IE rate on arrival and departure days. For Atlanta:
- Full Day M&IE: $86
- Travel Day M&IE (75%): $64.50
This rule applies regardless of what time the traveler arrives or departs. Even if someone arrives at 8 AM and works a full day, only 75% of M&IE is reimbursable for that calendar day.
Example Trip Cost Calculations
3-Day Atlanta Trip (Regular Season)
- Day 1 (arrival): $64.50 M&IE + no lodging = $64.50
- Day 2 (full day): $86 M&IE + $182 lodging = $268
- Day 3 (departure): $64.50 M&IE + $182 lodging = $246.50
- Total Trip Cost: $579
5-Day Atlanta Trip (Peak Season)
- Day 1 (arrival): $64.50 M&IE = $64.50
- Days 2-4 (full days): ($86 M&IE + $197 lodging) × 3 = $849
- Day 5 (departure): $64.50 M&IE + $197 lodging = $261.50
- Total Trip Cost: $1,175
A common error is calculating trips at the full daily rate ($268 × 3 = $804 for a 3-day trip), which overstates actual per diem by $225.
Georgia's GSA Rate Map: County-by-County Breakdown
Metro Atlanta Rate Boundaries
Atlanta's GSA locality covers Fulton and DeKalb Counties. For federal travelers, however, the applicable per diem rate is generally based on the location of the temporary-duty work activities rather than the location of the hotel. If lodging is unavailable at the work location, an agency may authorize the rate for the location where lodging is obtained.
Atlanta (Fulton/DeKalb Counties):
- Lodging Range: $182-$197
- M&IE: $86
- Notes: Includes downtown, airport area
Marietta (Cobb County):
- Lodging: $126
- M&IE: $74
- Notes: Only 5 miles from Atlanta
Standard CONUS (All other GA counties):
- Lodging: $110
- M&IE: $68
- Notes: 153 counties covered
Hartsfield-Jackson Atlanta International Airport spans county boundaries, with most of the airport located in Clayton County. Federal travelers should determine the applicable per diem based on their temporary-duty location and agency travel rules rather than assuming the Atlanta rate applies solely because the trip involves the airport. However, hotels in Cobb County (Marietta, Smyrna, Kennesaw) are only 5 miles away but have a $56-71 lower nightly cap.
Other Georgia Designated Localities
Six Georgia locations have rates above standard CONUS:
- Savannah (Chatham County): $147-$176/night, $80 M&IE. Peak season in March-April
- Jekyll Island/Brunswick (Glynn County): $172-$223/night, $86 M&IE. Peak season March-July (beach season)
- Athens (Clarke County): $136/night, $74 M&IE. Flat year-round
- Augusta (Richmond County): $110-$125/night, $74 M&IE. Lower in May-June
For teams traveling across Georgia, tracking which county each hotel sits in determines the applicable rate. A project with sites in Atlanta, Savannah, and a rural county could have three different per diem structures.
Tax Compliance and Accountable Plan Requirements
IRS Rules for Tax-Free Reimbursement
Per diem reimbursements are not taxable income when employers follow accountable plan rules.
The IRS requires an accountable plan to meet three core conditions:
- Business connection: The expenses must be incurred while performing services as an employee.
- Adequate accounting: Employees must substantiate expenses within a reasonable period of time.
- Return of excess: Employees must return reimbursements or allowances that exceed the amount properly accounted for within a reasonable period.
Under the IRS safe-harbor timing rules, expenses accounted for within 60 days and excess reimbursements returned within 120 days are treated as occurring within a reasonable period.
When these conditions are met, per diem payments do not appear on the employee's W-2 and are not subject to payroll taxes. For more detail on per diem taxes, the rules apply equally to federal and private sector travelers.
When Per Diem Becomes Taxable
Tax treatment depends on how the employer reimburses travel expenses. A per diem allowance paid above the applicable federal rate generally requires the excess allowance to be reported as wages. However, a private employer can reimburse properly substantiated actual business travel expenses under an accountable plan without treating the reimbursement as wages simply because the hotel cost exceeds the GSA lodging rate.
Reimbursements made under a nonaccountable plan are generally treated as taxable wages.
The lodging cap applies to the room rate only. Lodging taxes are excluded from the GSA cap and can be reimbursed separately without affecting the per diem calculation.
Lodging vs. M&IE Reimbursement Differences
A critical distinction for compliance:
- Lodging: Reimburse actual cost up to the GSA cap. If the hotel costs $165/night, reimburse $165, not the full $182 cap
- M&IE: Reimburse as a flat daily allowance. No receipts required, and employees keep any amount not spent
This means lodging requires documentation (hotel folio), while M&IE does not require itemized meal receipts. The IRS per diem guidance clarifies which expenses fall into each category.
Hotel Booking Strategies for GSA Compliance
Finding Properties Under the Cap
Atlanta's $182-$197 lodging cap allows flexibility in hotel selection. Booking strategies include:
- Government rates: Many chains offer GSA-specific rates below published prices
- Member rate programs: Corporate booking platforms often negotiate rates under GSA caps
- Location flexibility: Hotels slightly outside downtown often meet caps more easily
- Seasonal timing: The $197 January-March cap provides more options during peak convention season
Properties meeting GSA rates typically include select-service hotels, extended-stay properties, and mid-range chain locations. Downtown luxury hotels often exceed caps without government rate programs.
Common Booking Pitfalls
Errors that push bookings over GSA caps:
- Booking standard rates instead of requesting government or corporate rates
- Ignoring seasonal variation: Using $197 as the cap when traveling in April ($182 applies)
- Resort fees: Additional fees that push total nightly cost over the cap
- Wrong county: Booking in Marietta (Cobb County) expecting Atlanta rates ($126 vs. $182)
Pre-trip verification of the total nightly cost, including mandatory fees, prevents compliance issues at check-in.

Frequently Asked Questions
Do GSA per diem rates apply to private sector companies?
GSA rates are mandatory only for federal employees and contractors on federal travel. However, private companies frequently adopt GSA rates as their reimbursement benchmark because the rates are publicly available, updated annually based on market data, and provide a defensible standard for tax purposes. Using GSA rates simplifies policy administration and helps ensure reimbursements qualify for tax-free treatment under accountable plan rules.
How do I handle per diem when my company provides meals during a conference?
For federal travelers, the M&IE allowance is reduced when a meal is furnished by the government or included in a registration fee. At Atlanta's $86 M&IE rate, the applicable deductions are $22 for breakfast, $23 for lunch, and $36 for dinner. Complimentary meals provided by a hotel or motel and meals provided by a common carrier do not automatically reduce the federal per diem allowance. Private employers may establish different meal-deduction policies.
What happens if I cannot find a hotel under the GSA lodging cap in Atlanta?
When lodging at the applicable per diem rate is unavailable, a federal traveler may ask their agency to authorize actual-expense reimbursement. GSA recommends checking FedRooms for available rooms at the per diem rate. Under the Federal Travel Regulation, agencies may authorize or approve actual expenses up to 300% of the applicable maximum per diem rate in qualifying circumstances. Travelers should follow their agency's documentation and approval requirements.Private employers set their own actual expense policies.
Are Uber and Lyft costs covered under per diem or reimbursed separately?
Local transportation costs for taxis, rideshares, and public transit are not covered under M&IE per diem. These are reimbursed separately as transportation expenses with receipts. The incidentals portion of M&IE ($5/day for Atlanta) covers tips to porters, baggage handlers, and hotel staff, not ground transportation. Companies should clarify in their travel policies whether rideshare costs require pre-approval or have daily limits.
How do I calculate per diem for a trip that spans two different rate periods?
Apply the rate in effect for each travel date. For a trip from March 30-April 2, 2026 in Atlanta: March 30-31 use the $197 peak lodging rate, April 1-2 use the $182 regular rate. M&IE remains $86 throughout, with 75% on the first (March 30) and last (April 2) days. Each night's lodging is capped at the rate for that specific date, not an average across the trip.
Can employees keep the difference if their hotel costs less than the GSA cap?
No, for lodging. Lodging reimbursement is actual cost up to the cap, not a flat allowance. If the cap is $182 and the hotel costs $150, the reimbursement is $150. For M&IE, the answer is yes. M&IE is a flat daily allowance regardless of actual meal spending. An employee who spends $50 on meals still receives the full $86 daily allowance. This distinction reflects IRS substantiation requirements, where lodging requires documentation but M&IE does not.
