IRS Mileage Rate Update for 2026: Two Rates to Track Mid-Year

A single mileage rate will not work for 2026.
Under IRS Announcement 2026-11, the optional standard mileage rates changed effective July 1, 2026. That creates a split-year requirement for anyone using the standard mileage method for business, medical, or moving mileage. It is the first midyear adjustment since 2022, and it means mileage records need to show not only how many miles were driven, but when those miles were driven.
For clients, bookkeepers, tax preparers, and employers, the risk is simple: applying one flat rate to all of 2026 will produce the wrong deduction or reimbursement amount.
This article is for general informational purposes only and is not tax or legal advice. Tax rules can vary by taxpayer, entity type, and facts, so confirm treatment before filing or changing reimbursement policies.
The 2026 standard mileage rates changed on July 1
The IRS revised the optional standard mileage rates for the second half of 2026. The change applies beginning July 1, 2026, so the year now has two rate periods.
2026 date range | Business mileage | Medical and moving mileage |
January 1 through June 30 | 72.5¢ per mile | 20.5¢ per mile |
July 1 through December 31 | 76¢ per mile | 23.5¢ per mile |
The business mileage rate increased by 3.5 cents per mile for the second half of the year. The medical and moving rate increased by 3 cents per mile.
That may look small on a per-mile basis, but it adds up quickly for high-mileage taxpayers. A driver with 12,000 business miles in 2026 could have a materially different deduction depending on how those miles are split between the first and second half of the year.
The key point is that the rate is tied to the date the miles were driven, not the date a reimbursement is paid, the date a report is submitted, or the date a return is prepared.
Who needs to track two rates for 2026
The split applies broadly to taxpayers and organizations using the standard mileage method. It can affect both deductions and reimbursement calculations.
Common affected groups include:
Schedule C filers who deduct business vehicle mileage
Gig workers who drive for work
Real estate professionals who travel between properties, showings, and client appointments
Consultants, contractors, and sales professionals using a personal vehicle for business
Employers reimbursing employees under an accountable plan
Bookkeepers processing mileage reports
Tax preparers calculating year-end deductions
For many taxpayers, the issue will not be whether the mileage qualifies. The issue will be whether the mileage log has enough detail to apply the correct rate.
A year-end total such as “18,400 business miles for 2026” is no longer enough on its own. The preparer or bookkeeper needs those miles separated between:
January 1 through June 30
July 1 through December 31
If the log shows dates for every trip, the split is straightforward. If it does not, the taxpayer may need to reconstruct the records using calendars, invoices, job logs, dispatch records, route histories, or other reliable supporting documents.
Why a single annual mileage rate creates errors
The standard mileage method is often treated as simple. Multiply business miles by the IRS rate, enter the result, and move on.
That approach breaks down in a midyear rate change.
For 2026, the calculation has to happen in two parts:
First-half qualifying miles multiplied by the first-half rate
Second-half qualifying miles multiplied by the second-half rate
Then the two amounts are added together.
For business mileage, the calculation looks like this:
January 1 through June 30 business miles × $0.725
+
July 1 through December 31 business miles × $0.76
=
Total 2026 business mileage deduction or reimbursement
For medical or moving mileage, the same structure applies, but with the medical and moving rates:
January 1 through June 30 medical or moving miles × $0.205
+
July 1 through December 31 medical or moving miles × $0.235
=
Total 2026 medical or moving mileage amount
A single blended estimate may be tempting, but it can create problems. The IRS did not issue one annual rate for all 2026 mileage. It issued rates for two distinct periods.
For 2026, the date of each trip matters as much as the number of miles.
That is the practical takeaway from the IRS Mileage Rate Update for 2026. The math is not difficult, but the records need to support it.
What counts as good split-year mileage support
The strongest mileage record shows each trip with enough detail to establish the deduction or reimbursement.
A useful mileage record usually includes:
Date of the trip
Starting location and destination
Business, medical, or moving purpose
Miles driven
Vehicle used
Notes tying the trip to a client, job, property, appointment, or qualifying purpose
For 2026, the date field becomes even more important. It determines which rate applies.
A mileage app may already capture this automatically. A spreadsheet can work too, as long as it includes dates and totals by period. Paper logs are also acceptable when kept consistently and supported by other records.
The weak point is summarized mileage without dates. For example, a taxpayer may know they drove 9,000 business miles during the year, but if they cannot show how many were driven before and after July 1, the rate calculation becomes harder to support.
A simple example shows the effect
Assume a self-employed consultant drove 10,000 qualified business miles in 2026.
If the miles were split evenly:
Period | Miles | Rate | Amount |
January 1 through June 30 | 5,000 | $0.725 | $3,625 |
July 1 through December 31 | 5,000 | $0.76 | $3,800 |
Total | 10,000 | $7,425 |
If someone used only the first-half rate for all 10,000 miles, the calculation would be $7,250. That would understate the deduction by $175.
If someone used only the second-half rate for the full year, the calculation would be $7,600. That would overstate the deduction by $175.
The same kind of error can happen with employer reimbursements. If an employer reimburses all 2026 business mileage at one rate, some employees may be underpaid or overpaid under the company’s stated policy.
Employers should review accountable plan language now
Employers that reimburse mileage under accountable plans should look closely at their policies.
Many policies refer to “the IRS standard mileage rate” or “the federal mileage rate.” That shorthand may have been harmless in a normal year, but in 2026 it needs more precision.
A policy should make clear which rate applies based on the date of travel. If the company uses the IRS rate, the policy should recognize that there are two 2026 business mileage rates:
72.5 cents per mile for business miles driven from January 1 through June 30
76 cents per mile for business miles driven from July 1 through December 31
Payroll and accounts payable teams should also check their reimbursement systems. A system that stores only one mileage rate for the entire calendar year may need a manual update, a second rate code, or a date-based rule.
Accountable plan reimbursements generally require employees to substantiate the business purpose, time, place, and amount of the expense within a reasonable period. For mileage, that means trip-level detail matters. In 2026, it also means the date must be clear enough to assign the correct rate.
Bookkeepers and preparers should update workflows before year-end
The easiest time to fix 2026 mileage tracking is before records pile up.
Bookkeepers and preparers can reduce year-end cleanup by adding a split-year check to monthly or quarterly workflows. The change does not need to be complicated, but it should be explicit.
A practical workflow could include:
Ask for trip-level records
Do not accept only an annual mileage total unless there is backup showing how the miles were divided.
Create two mileage categories
Use separate spreadsheet tabs, expense categories, or software tags for January through June and July through December.
Confirm the mileage purpose
Business, medical, and moving mileage use different rates. Personal mileage does not qualify.
Review reimbursement policies
If an employer reimburses at the federal rate, make sure the second-half rate starts with miles driven on or after July 1, 2026.
Document any reconstruction
If records need to be rebuilt, keep the source documents used to support the split.
This is also a good time to remind clients that commuting is not business mileage. Driving from home to a regular work location usually does not qualify as deductible business mileage, even if the taxpayer tracks the miles carefully.
Different taxpayer types face different pain points
The split-year rule is the same, but the record-keeping problem can look different depending on the taxpayer.
Schedule C filers often need cleaner logs
Sole proprietors and independent contractors frequently use mileage as a major deduction. For them, a missed rate change can affect taxable income directly.
A good 2026 Schedule C mileage summary should show:
Total business miles from January 1 through June 30
Total business miles from July 1 through December 31
Total personal miles, if needed for vehicle records
Total miles driven for the year
Support for business purpose and dates
The preparer should not have to guess how to split the year.
Gig workers may need platform and calendar support
Gig workers often receive mileage summaries from apps or platforms, but those summaries may not include every deductible mile. For example, a driver may have qualifying miles between rides, deliveries, pickups, or related business errands depending on the facts.
A date-based mileage log helps capture the complete picture. If a platform report does not split mileage at July 1, the taxpayer may need to export activity reports and separate the records manually.
Real estate professionals should separate property travel
Real estate professionals can have many short trips, including showings, inspections, supply runs, listing appointments, and travel between properties. These trips can be easy to undercount.
A 2026 log should connect each trip to a property, client, listing, or business task. The split-year rate change makes vague monthly totals less useful.
Employers need consistent employee reimbursement rules
Employers should avoid reimbursing one employee at the first-half rate and another at the second-half rate for the same July trip unless there is a clear policy reason.
The safest approach is date-based consistency. If the travel occurred before July 1, use the first-half rate. If it occurred on or after July 1, use the second-half rate.
Medical and moving mileage should not be overlooked
The business rate usually gets the most attention, but the medical and moving mileage rates also changed on July 1, 2026.
For medical mileage, the rate increased from 20.5 cents per mile to 23.5 cents per mile for the second half of the year.
Moving mileage is more limited under current federal rules than it once was. In general, the federal moving expense deduction has been suspended for many taxpayers, with an exception for certain active-duty members of the Armed Forces moving under military orders. Taxpayers should confirm eligibility before claiming moving mileage.
The split-year concept still applies where the mileage is eligible. First-half medical or moving miles use the first-half rate. Second-half medical or moving miles use the second-half rate.
A practical checklist for the rest of 2026
The midyear increase is manageable if records are updated now. The problems come later, when someone tries to split a year of mileage after the details have faded.
Use this checklist for 2026 mileage files:
Update mileage apps, spreadsheets, and reimbursement systems for the July 1 rate change.
Separate January through June miles from July through December miles.
Keep trip dates, destinations, mileage, and business or qualifying purpose.
Review employer accountable plan language that references the federal rate.
Recalculate any July or later reimbursements that were paid using the old rate.
Make sure medical and moving mileage, when eligible, use the correct period rate.
Avoid using one annual mileage rate for all 2026 miles.
The IRS standard mileage method is still a simple way to calculate vehicle deductions and reimbursements, but 2026 requires one extra layer of care. The rate changed midyear, so the records need to match the calendar.
The best next step is to update tracking systems now, before year-end totals blur the line between the two periods. For every 2026 mileage report, the core question should be direct: were those miles driven before July 1 or on and after July 1?
