The IRS mileage rate 2027 has not been announced yet, but every self-employed driver and business owner wants to know where the rate is heading. Based on the historical trend from 67 cents in 2024 to 70 cents in 2025 and 72.5 cents in 2026, there is strong reason to expect another increase. Here is what the data tells us about what the 2027 standard mileage rate could be.
How the IRS Sets the Standard Mileage Rate
Before diving into our IRS mileage rate 2027 prediction, it helps to understand how the rate is determined. The IRS does not pick a number out of thin air. Each year, the agency commissions an independent study of the actual costs of operating a vehicle in the United States. That study examines both fixed and variable expenses.
Fixed costs include vehicle depreciation, insurance premiums, registration fees, and license costs. These do not change based on how many miles you drive. Variable costs include fuel, oil, tires, and routine maintenance, all of which increase the more you drive.
The IRS combines these findings into a single per-mile figure that represents the average cost of operating a car for business purposes. The result is the standard mileage rate, announced each December for the following tax year.
For a full breakdown of how this rate works, see our guide on the 2026 IRS mileage rate.
Historical IRS Mileage Rate Trend (2020-2026)
Looking at the historical pattern reveals a clear upward trajectory over the past several years.
| Year | Business Rate | Change |
|---|---|---|
| 2020 | 57.5 cents | - |
| 2021 | 56.0 cents | -1.5 cents |
| 2022 | 58.5 / 62.5 cents | Mid-year increase |
| 2023 | 65.5 cents | +3.0 cents |
| 2024 | 67.0 cents | +1.5 cents |
| 2025 | 70.0 cents | +3.0 cents |
| 2026 | 72.5 cents | +2.5 cents |
After a brief dip in 2021 when pandemic-era driving dropped sharply, the rate has climbed every single year. The pace of increase has averaged roughly 2.5 cents per year since 2023. This pattern suggests the 2027 rate will likely continue upward.
Five Factors That Will Shape the 2027 Rate
The IRS mileage rate 2027 will be determined by five key cost categories. Here is how each one is trending.
1. Fuel Prices
Gasoline remains the single largest variable cost of driving. While fuel prices have stabilized compared to the 2022 spike, they remain elevated above pre-pandemic levels. If oil prices stay in their current range, fuel will exert moderate upward pressure on the rate. A significant drop in gas prices could slow the rate increase, while a supply disruption could push it higher.
2. Auto Insurance Premiums
Insurance has been the strongest driver of rate increases in recent years. Premiums have surged due to rising repair costs, more expensive vehicles on the road, and increased claim frequency. Auto insurance costs are unlikely to reverse course quickly, making this a near-certain factor pushing the 2027 rate higher.
3. Vehicle Depreciation
New and used car prices directly affect the depreciation calculation built into the mileage rate. The depreciation component has been rising steadily in recent years as vehicle prices climbed. While the used car market has cooled somewhat from its 2022 peak, vehicle prices remain historically high, which supports continued depreciation pressure.
4. Maintenance and Repair Costs
Labor rates at auto shops continue to climb. Parts costs remain elevated due to the increasing complexity of modern vehicles, particularly those with advanced driver-assistance systems and hybrid or electric drivetrains. Maintenance and repair costs have shown the strongest statistical correlation with rate adjustments over the past decade.
5. General Inflation
Broader economic inflation affects every component of vehicle operation. While the overall inflation rate has moderated from its 2022-2023 highs, transportation-sector inflation remains sticky. The Consumer Price Index for transportation services continues to outpace general inflation, which supports a higher mileage rate.
Our IRS Mileage Rate 2027 Prediction
Taking all of these factors into account, we predict the 2027 IRS standard mileage rate for business use will land between 74 and 76 cents per mile. Here is our reasoning.
Most likely scenario (74-75 cents): Insurance and maintenance costs continue their steady climb while fuel prices remain stable. The IRS increases the rate by 1.5 to 2.5 cents, consistent with the recent trend. This is the most probable outcome.
Higher-end scenario (76+ cents): A spike in fuel prices combines with persistent non-fuel inflation to push operating costs significantly higher. The IRS responds with a larger increase, similar to the 3-cent jumps seen in 2023 and 2025.
Lower-end scenario (73-74 cents): Fuel prices drop meaningfully, and the used car market softens enough to slow depreciation growth. The IRS still raises the rate due to insurance and maintenance costs, but by a smaller margin.
It is important to emphasize that these are predictions, not confirmed figures. The IRS will announce the official 2027 rate in December 2026, based on data gathered throughout the year.
What a Higher Rate Means for Your Tax Deduction
Even a small increase in the mileage rate has a real impact on your bottom line. If you drive 20,000 business miles per year, here is how the numbers compare:
| Rate | Annual Deduction | Difference from 2026 |
|---|---|---|
| 72.5 cents (2026) | $14,500 | — |
| 74 cents | $14,800 | +$300 |
| 75 cents | $15,000 | +$500 |
| 76 cents | $15,200 | +$700 |
That extra $300 to $700 can make a meaningful difference for self-employed drivers, freelancers, and small business owners who depend on the standard mileage deduction vs. actual expenses method.
How to Prepare for the 2027 Mileage Rate
Regardless of where the rate lands, the most important thing you can do is track every business mile accurately. The IRS requires a contemporaneous log that records the date, destination, business purpose, and odometer reading for each trip. Without proper records, you cannot claim the deduction at all.
Here are three steps to get ready:
-
Start tracking now. Do not wait until the rate is announced. Every business mile you drive today counts toward your deduction next April. Learn how to calculate mileage for taxes so you are prepared.
-
Use an automatic tracking method. Manual logs are error-prone and easy to forget. A GPS-based mileage tracker captures every trip without effort.
-
Keep records organized. Store your mileage log alongside receipts for tolls and parking, which are deductible on top of the standard mileage rate.
