I had a March trip and a September trip and I almost priced both at one number. The IRS table for 2026 has two rows. Business miles through 30 June are 72.5 cents. Business miles from 1 July are 76 cents. A page that only says "the 2026 rate" is already wrong by July.
I built a tab that looks up the rate from the date, names the notice, and lets a custom cents-per-mile sit next to it without wearing an IRS label. The trips stay in the tab. Mixpanel still loads with Softery.io, so I will not claim the whole site never talks to a server.
The new page is IRS Mileage Reimbursement Calculator.
One year, two rates
The sample is two lines.
2026-03-04, 18 miles, Supply run
2026-09-15, 42.5 miles, Client visit
18 miles on 4 March at 72.5 cents is $13.05. 42.5 miles on 15 September at 76 cents is $32.30. The total is $45.35.
If I had used 76 cents for both, 60.5 miles would be $45.98. That is 63 cents too high. If I had used 72.5 cents for both, the same miles would be $43.86. That is $1.49 too low. Neither miss is dramatic on two trips. A year of driving makes it a real number. The page prices each date on its own row so I do not have to remember which half I am in.
The year menu browses the table. It does not override a trip. If I am looking at 2024 and the date says 15 September 2026, the dollars still come from 2026. The source sits on the line.
Where I read the numbers
I read the IRS standard mileage table on 28 July 2026. The page is the one titled Standard mileage rates. It lists every period from 2011 through the second half of 2026, with a source code on each row. That table is the snapshot in this tab. I did not type a rate from memory and I did not keep last year's figure because the year number matched.
The first half of 2026 comes from IR-2025-128, dated 29 December 2025. That release points at Notice 2026-10. Beginning 1 January 2026 it set:
| Use | Cents per mile |
|---|---|
| Business | 72.5 |
| Medical | 20.5 |
| Moving, for the people the notice names | 20.5 |
| Charitable | 14 |
The second half comes from Announcement 2026-11, in Internal Revenue Bulletin 2026-29, dated 13 July 2026. The IRS table labels that row IR-2026-29. It revises the rates for transportation on or after 1 July 2026, and for mileage allowances paid on or after that date for expenses paid on or after that date. Business becomes 76 cents. Medical and moving become 23.5 cents. The announcement says the change follows a rise in the price of fuel. It also says the rest of Notice 2026-10 stays in effect.
A date in 2010 or in 2027 gets no rate. The line says the snapshot has no IRS rate for that date. I will not borrow December 2026 for a January 2027 trip. When the next notice lands, the snapshot is a separate update. This page does not fetch the IRS site while you type.
Charity did not move
14 cents is the charitable rate in every row of the table I copied, from 2011 through 2026. Announcement 2026-11 says that rate is fixed under section 170(i) of the Internal Revenue Code. Fuel went up. Charity stayed.
If the drive was for a charity, pick Charitable. Leaving the category on Business will price 42.5 miles at $32.30 instead of $5.95. That is not a rounding quibble. It is the wrong column.
The page will not decide that your drive was charitable. You pick the category. The notice is printed next to the cents so you can see which rule you used.
Medical and moving share a column
The IRS table has one cents column labelled "Medical or military moving." On 1 August 2026 that number is 23.5. On 1 March 2026 it is 20.5. Medical and moving use the same cents. They are not the same permission.
Moving is the narrow one. Notice 2026-10, and the 29 December release, name certain active-duty members of the Armed Forces who move under orders, and certain members of the intelligence community who move after 31 December 2025. Earlier years in this snapshot are the military case. The July table heading on the IRS page even says "Moving (military only)" for the second half, while the notice text is a bit wider. I am not going to collapse that into a cheerful "moving rate for everyone."
The category note on a moving line says the cents match medical, and that this page does not decide whether a move qualifies. A reimbursement calculator that also files your return would be a different product. This one multiplies.
2022 already did this
This is not the first mid-year change in the table. From 1 January through 30 June 2022 the business rate is 58.5 cents, source IR-2021-251. From 1 July through 31 December 2022 it is 62.5 cents, source IR-2022-124. 2011 splits too: 51 cents through 30 June, 55.5 cents after, sources IR-2010-119 and IR-2011-69.
A tool that stores one number per calendar year will be wrong on those years the same way it is wrong on 2026. The lookup here is a start date and an end date, inclusive. 30 June 2026 is 72.5. 1 July 2026 is 76. The boundary is the date on the trip, not the year you typed in a box.
2025, for a trip that really was in 2025, is one row: business 70 cents, medical 21, charity 14, source IR-2024-312. 2024 is business 67 cents, medical 21, charity 14, source IR-2023-239. I am not going to list all nineteen periods in this post. They are on the page, next to the year menu, with the source code the IRS printed.
A kilometre is not a mile
The IRS rate is per mile. If the odometer is in kilometres, dividing by 1.6 is a shortcut that drifts. This page uses the international mile, 1,609.344 metres, then multiplies, then rounds the money once.
Ten kilometres of business driving on 15 September 2026 is $4.72. The mile figure shown on the line is 6.214 miles, which is the conversion rounded to three decimal places for you to read. The dollars were not computed from that rounded mile figure and then rounded again. One rounding, at the cent.
Use a dot for the decimal. 10,5 is not ten and a half. Three decimal places is the cap, which covers an odometer that shows tenths. Past 100,000 the line stops. That is not a trip log. It is a paste that will make the tab miserable, so the rest is refused.
Half a cent goes up
23.5 cents times one mile is 23.5 cents of money. The page rounds half up, so one medical mile on 1 August 2026 is $0.24. 10.1 charitable miles at 14 cents is 141.4 cents, which is $1.41, because 0.4 is not a half.
42.5 times 76 cents is $32.30 exactly. 18 times 72.5 cents is $13.05 exactly. I checked those with integer tenths of a cent so a binary float could not shave a penny. If the report says something else, the export is wrong. Open the file.
A custom rate is not the IRS rate
Some handbooks pay 50 cents, or 67, or whatever the policy said in January. Type that in Custom cents per mile. The line says "Not an IRS rate" and still tells you the IRS figure for that date, so the gap is visible. I am not going to stamp your policy number with IR-2026-29.
On the sample, 50 cents times 60.5 miles is $30.25. That is your policy, not the table. The share link does not carry the custom cents. It carries the category, the unit, and the year you were browsing. A cache buster like v= is not a knob. I already watched a missing year knob turn a calendar into year 1. I am not repeating it.
The trips, the purposes, and the distances are not in that link and they are not in local storage. Close the tab and the list is gone. Clear settings puts business, miles, the IRS rate, and 2026 back, and removes softery.irs-mileage-reimbursement-calculator.settings. The list stays until you clear the trips or close the tab.
The depreciation piece stays inside the rate
Notice 2026-10 says the portion of the business standard mileage rate treated as depreciation is 35 cents per mile for 2026. It also lists 33 cents for 2025, 30 for 2024, 28 for 2023, and 26 for 2022. Announcement 2026-11 left the rest of that notice in place, so I did not invent a second depreciation number for July.
A reimbursement uses the full standard rate. One business mile in the second half of 2026 is 76 cents, not 76 minus 35. Subtracting the depreciation piece would be a basis question for a car you own and deduct, which is not what this page is doing. The report does not print 41 cents and call it the rate.
The file you can open
Copy report, Download .txt, Download .csv, and Download .pdf write the same trips: date, distance, unit, miles, category, cents per mile, dollars, purpose, and the source. The csv total line is the sum of the priced rows. A row with a bad date is left out of the total and named in the text report.
Undo walks the trip list, up to forty steps. Remove a row, paste a sheet, use the sample. Undo puts the previous list back. The paste format is date, distance, purpose, with an optional header. A line that is not YYYY-MM-DD is skipped and the line number is shown. I am not going to invent a date from "Tuesday."
This is a reimbursement at the published rate. It is not a tax deduction.
That sentence is on the page and in the pdf. A deduction is a line on a return. This tab does not file one. It also does not tell you the trip qualifies. Optional standard mileage rates are optional. The December release says you may use actual costs instead. I am not comparing the two methods here. That is a different job, and I do not have your receipts.
What I left out on purpose
No GPS. No account. No drive cap beyond the 100,000 distance stop and 500 pasted rows. No claim that an app is "IRS approved." The IRS asks for a record of the miles. A contemporaneous log is the thing the instructions keep pointing at. This page will hold the lines while the tab is open and write them to a file you download. It will not store them for next week. If you need the log later, keep the file.
It will not call one cents figure "the 2026 rate" without a date. It will not treat a reimbursement as the deduction. It will not decide a move. It will not restore a rate the snapshot does not have.
Mixpanel and Google Analytics load with Softery.io. They see that someone opened the tool, which knob moved, a size bucket, and a dollar band. They do not see the dates, the purposes, or the miles.
After the total
If the dollars need to go on a bill, Invoice Generator is the next page. If the sheet still has broken columns, CSV Viewer and Editor will open it in the tab. I checked both routes before I put the links on the page. I am not going to invent a gas-mileage URL that does not exist.
Price the date you actually drove
- Open IRS Mileage Reimbursement Calculator.
- Use the sample, or paste your own lines.
- Read the total. March should be 72.5 cents. September should be 76. The sum of those two sample lines is $45.35.
- Switch to Charitable if the drive was not business. 14 cents should replace 76.
- If your policy is not the IRS rate, type the cents and read the line that says it is not an IRS rate.
- Download .csv or .pdf and open the file. The source code should be on the row.
If September is still 72.5, the page is wrong. If the share link contains the purpose, the page is wrong.
