> Total the actual car expenses deduction from bank statements: gas, repairs and insurance rows, the business-use share, and mileage.
The actual car expenses deduction is the business share of what the car really cost you in a year: gas, repairs, insurance, registration, tires and depreciation. Bank and card statements give you the yearly totals for most of those. A mileage log gives the share, business miles divided by all miles, and that percentage turns the totals into the deduction.

## What counts toward the actual car expenses deduction?

The actual car expenses deduction counts the costs of owning and running the car, not only fuel. [IRS Publication 463, Travel, Gift, and Car Expenses](https://www.irs.gov/publications/p463) lists depreciation, lease payments, registration fees, licenses, insurance, repairs, gas, garage rent, tires, oil, tolls and parking fees as actual car expenses. Each is added up for the year, then cut to the business share.

### Costs that come from statements

- **Gas**, from card and debit rows at fuel stations.
- **Repairs and maintenance**: oil changes, tires, brakes, inspections.
- **Insurance**, often paid monthly or twice a year.
- **Registration and license fees** paid to the state.
- **Lease payments**, if you lease rather than own.
- **Garage rent**, if you rent a space for the car.
- **Business parking and tolls.**

### Costs that do not come from statements

Depreciation is figured from what you paid for the car, using the rules in Publication 463, so no monthly row shows it. Car loan interest appears inside a loan payment, and the lender's statement splits interest from principal. Commuting is a cost you pay but cannot claim: Publication 463 says commuting costs are not deductible, so trips from home to a regular workplace do not count as business miles.

## Pulling car expense rows out of bank and card statements

Car expense rows are scattered across a year of checking and card statements, mixed in with groceries and rent. The quickest way to collect them is to get every row into one spreadsheet, filter by payee for fuel stations, garages, insurers and the motor vehicle office, and give each matching row a car category.

### A search list for car rows

Filter the description column for words your statements tend to use. These are examples; your bank's wording will differ.

- Fuel brands and words like "FUEL", "GAS" or "PETRO".
- "AUTO", "TIRE", "LUBE", "SERVICE" for maintenance shops.
- Your insurer's name.
- "DMV", "MVD" or your state's motor vehicle agency.
- "PARKING", "PARK" and toll agency names.

A fuel station row is not always fuel. A 14.50 charge at a gas station might be coffee and a snack. Rows under a small amount at a fuel brand are worth a second look, and anything you cannot place belongs in a notes column rather than the total.

### Getting the rows out of PDFs

If your bank offers a CSV download for the year, use it. If not, a converter turns the monthly PDFs into rows you can filter. [CheapBankConvert](/) is preparing to launch with one-time pricing per statement and a five-statement bundle, so a year of card and checking statements does not need a subscription. It is in early access for now.

### When a repair bill is disputed

Sometimes the statement row is the only clear record of a repair that went wrong, such as a garage that charged for work it did not finish. The same rows that build the deduction can support a claim, as described in [using bank statements as small claims court evidence](/blog/bank-statements-for-small-claims-court).

## Business-use share: a mileage log against total car miles

The business-use share is business miles divided by total miles driven in the year. Publication 463 gives the example of 12,000 business miles out of 20,000 total, which is 60%, so only 60% of the operating costs count. Your statements give the costs. Only a mileage log gives the share, and without one the totals have nothing to multiply.

### What the log needs

Publication 463's recordkeeping chapter says the records for a car include the date you started using it for business, the mileage for each business use, and the total miles for the year. It says records should be made at or near the time of use, and a weekly log that accounts for the week's use counts as timely. A simple log has these columns:

| Date | Start odometer | End odometer | Miles | Destination | Business purpose |
| --- | ---: | ---: | ---: | --- | --- |
| 2025-02-03 | 41,220 | 41,268 | 48 | Client office, Elm St | Quarterly review |
| 2025-02-05 | 41,301 | 41,333 | 32 | Supply store | Printer paper and toner |

The values in that table are examples. Record the odometer on January 1 and December 31 too, so total miles for the year come from the car rather than a guess.

### Statements can help rebuild a log

Statements do not replace a log, but they can help you fill gaps. A parking charge downtown on a date with no log entry may jog your memory of a client visit, and a toll row puts the car on a road on a given day. Use them as prompts, then write the entry with its business purpose.

## Actual car expenses or the standard mileage rate: which comes out higher?

The standard mileage rate multiplies business miles by a fixed rate set each year, and replaces most of the actual costs. Publication 463 gives 70 cents a mile for 2025 and says that if you use the standard rate for a year, you cannot deduct your actual car expenses for that year. Work out both figures and compare.

Actual costs tend to win when the car is expensive to run per mile: a costly vehicle with high insurance and repairs, or a car driven few total miles but mostly for business. The standard rate tends to win for a cheap, efficient car that covers many business miles. Neither is a rule. The numbers in your statements decide it.

### What you can add under either method

Publication 463 says business parking fees and tolls are deductible on top of the standard mileage rate. It also notes that car loan interest may be deductible even when you use the standard rate. So the parking and toll rows you filtered from statements matter whichever method you choose.

## Car deduction trap: the first-year method choice

The choice made in the car's first business year can limit later years. Publication 463 says that to use the standard mileage rate for a car you own, you must choose it in the first year the car is available for business use. After that, either method is open. Starting with actual expenses can close that door.

### Why it matters for statements

If the first year's statements show modest costs, the standard rate may look like the easy choice, and it keeps both options open later. If you start with actual expenses, you have committed to tracking those costs from statements every year. Publication 463 also says that switching from the standard rate to actual expenses later, before the car is fully depreciated, requires straight-line depreciation over the car's remaining useful life. That is a calculation to hand to a preparer.

### A second car changes the arithmetic

Households with two cars sometimes use whichever car is free for business trips. Each car then needs its own log, its own share and its own tab of statement rows. A single blended percentage across both cars hides which one did the business driving, and a statement row for new tires has to land on the right vehicle. Label each row with the car before you total anything.

### Other traps

- **No log.** Totals without a mileage log cannot be cut to a business share.
- **Counting commutes** as business miles.
- **Claiming 100%** of a car that also does the school run.
- **Counting a card payment and the card's fuel rows.** Use the purchases, not the payment that paid them off.
- **Mixing two cars** in one total. Keep a tab per vehicle.

If you find that an earlier return used the wrong figure or skipped car costs you could have claimed, the steps for [amending a tax return for missed deductions](/blog/amend-a-tax-return-for-missed-deductions) explain how to correct it.

## A worked actual car expense total for one example year

The worked example below uses invented figures for one owned car with a 60% business share. It shows the shape of the calculation, not a typical result.

| Category | Statement rows | Yearly total | Business share | Counted |
| --- | ---: | ---: | ---: | ---: |
| Gas | 46 | 2,180.00 | 60% | 1,308.00 |
| Repairs and maintenance | 5 | 1,240.00 | 60% | 744.00 |
| Insurance | 12 | 1,560.00 | 60% | 936.00 |
| Registration | 1 | 210.00 | 60% | 126.00 |
| Tires | 1 | 640.00 | 60% | 384.00 |
| Subtotal | | 5,830.00 | | 3,498.00 |
| Depreciation (from preparer) | | | | figured separately |
| Business parking and tolls | 18 | 310.00 | 100% | 310.00 |

Business parking and tolls are shown at 100% because those rows are business trips by definition; personal parking stays out entirely. With 12,000 business miles, the standard rate for 2025 would give 12,000 times 0.70, which is 8,400.00, plus the 310.00 in parking and tolls. Before depreciation, the actual figure here is lower. Depreciation could change that, which is why the comparison is done with the preparer's figure in place.

### Records to keep with the total

Publication 463 says records supporting a deduction are generally kept for three years from filing, and for a car, records of business use are kept for each year of the recovery period. Keep the log, the statement sheet and the statements themselves together.
