For the 2023 fiscal year (which ran from October 1, 2022, to September 30, 2023), the standard IRS/GSA per diem rate for the continental United States (CONUS) was $157 per day, consisting of $98 for lodging and $59 for meals and incidental expenses (M&IE). However, for "high-cost" localities like New York City, San Francisco, or Washington D.C., the rates were significantly higher, often exceeding $300 per day. For those in the transportation industry, the special M&IE rates were $69 for CONUS and $74 for OCONUS (outside the continental US). In 2026, many corporate travelers still look back at these 2023 rates as a benchmark for post-pandemic travel budgeting. It is important to note that these rates are meant to cover "ordinary and necessary" business expenses; if your company pays you more than the federal rate, the excess may be treated as taxable income unless you provide receipts for the actual costs incurred.
