Business Vehicle in Your Books: Fuel, Repairs, Insurance and Personal Use, Kept Separate

Why a business vehicle needs its own lines

A vehicle is one of the easiest places for the books to get muddy. One truck does the work runs, the errands and the family trips. The fuel card pays for all of it. The repair shop bills the whole truck. If every cost goes to one line called auto expenses, no one can tell what was business and what was personal at the end of the year.

The fix is to give each vehicle cost its own line. Fuel goes to vehicle fuel. Repairs go to vehicle repairs. Insurance goes to vehicle insurance. Registration, oil changes and tires each land in their own spot. When the month closes, the totals are already in the right places, and the personal use is kept out.

We set the lines up once in QuickBooks Online or Xero, and the same lines run every month. The bank feed does some of the work, but we review every line, so a bad feed rule does not send a personal cost to a business line all year.

Here is what happens when the lines are set up right.

When each cost has its own row, the books tell the story of what the vehicle really cost to run.

What goes in the vehicle lines

The vehicle lines hold the real costs of keeping the truck or van on the road. Fuel is the big one. Repairs come and go. Insurance is paid on a schedule. Registration shows up once a year. Oil changes and tires wear out on their own time.

Each one gets its own account in QuickBooks. The reason matters because a year of fuel is a big number, and a year of repairs is a different big number. If they share one row, you can not see which one grew. We keep them apart, so the totals stay clear.

The receipts and the bills are the proof. Every fuel receipt, every repair invoice, every insurance bill and every registration notice gets tied to the transaction in the books. When the month closes, the cost is in the right line and the proof is on file.

Here is what we keep on file for each vehicle.

• **The fuel receipts: ** each one tied to the transaction in the books.
• - **The repair and maintenance bills: ** each one in its own line, not piled in one row.
• - **The insurance bills: ** each one recorded and on file.
• - **The registration notice: ** recorded when it comes in, once a year.
• - **The oil change and tire receipts: ** each one tied to the transaction.

Keep the records in one place. We tie them to the books as we go, so nothing is missing at year end.

Keeping personal use out of the business books

A business vehicle is also a personal vehicle a lot of the time. The truck drives the crew to the job in the morning and the family home at night. The van hauls the tools on Tuesday and the groceries on Saturday. The costs are real, but only the business share belongs in the business books.

The clean way is to keep the business costs in the books and the personal use out. When the vehicle is used for both, the business costs go in their own lines, and the personal use is noted but not counted as a business cost. Your CPA decides how the split works. We keep the records clean so they have good numbers to start from.

A mileage log helps here. The log shows how many miles were business and how many were personal. Even when you track the actual costs, your CPA needs the business miles to figure the share. We make sure the log and the books tell the same story.

Here is what to do when a vehicle is used for both.

• **Keep a mileage log of the business miles.** The date, the trip and the miles go in the log the same week.
• - **Record the full vehicle costs in their own lines.** Fuel, repairs, insurance and the rest each in their own spot.
• - **Do not put the personal share in the business books.** It does not belong there, even if the same vehicle is used for both.
• - **Keep the odometer reading at the start and end of the year.** It shows the total miles and helps your CPA see the split.
• - **Tie every business receipt to the transaction.** The proof stays on file so nothing is missing at year end.

The split is your CPA's call. We keep the costs in the right lines and the personal use out, so the books are clean either way.

The records that hold it together

A business vehicle in the books needs a few records to stay clean. The lines in QuickBooks are the big one. The mileage log is the check. The receipts and the bills are the proof that the vehicle was on the road.

We keep the vehicle costs in their own lines, not in one general row. We tie the receipts to the transactions. We keep the full bills on file. We note which vehicle each cost belongs to if you have more than one. And we track the odometer reading at the start and end of the year, because your CPA needs it either way.

If you run more than one vehicle for the business, each one gets its own set of lines. The fuel for truck one does not mix with the fuel for truck two. The repairs for each one stay in their own rows. That way the cost per vehicle is clear, and a big bill on one truck does not hide in the total for the whole fleet.

Here is what we keep on file for each vehicle.

• **The mileage log: ** the date, the trip and the miles for every business drive.
• - **The odometer reading: ** at the start and end of the year for each vehicle.
• - **The fuel receipts: ** each one tied to the transaction.
• - **The repair and maintenance bills: ** each one in its own line.
• - **The insurance and registration bills: ** each one recorded and on file.
• - **A note on the method: ** whether your CPA picked the mileage method or actual costs.

Keep the records in one place. We tie them to the books as we go, so nothing is missing at year end.

What your CPA decides, not us

We keep books and run payroll. We do not prepare taxes. We do not give tax advice. We do not tell you what share of your vehicle to claim or which method saves you more. Those are calls for your CPA or tax preparer.

What we do is keep the records clean so your CPA has good numbers to start from. The lines are set up right. The receipts are tied to the bills. The personal use is kept out. The mileage log is kept up. Your CPA can read the books and make the calls.

When the tax questions come up, we point you to your CPA. We answer their questions about the books, but we do not give the advice. You can read more about how we keep the books on our bookkeeping page, and about payroll on our payroll page.

A situation we clean up

The one line called auto expenses

A small business owner runs two trucks for the work and drives one of them home at night. Every fuel receipt, every repair bill and every insurance payment goes to one line called auto expenses. No mileage log. No split between the trucks. No note on what was personal. At year end, the CPA asks how much of each truck was business and how much was personal. The owner can not tell from the books, and the receipts are in no order.

Here is how we handle it. We set up separate lines for each vehicle cost. We sort the receipts and tie each one to the transaction in the books. We split the costs by truck, so each one has its own fuel and repair rows. We start a mileage log going forward, with the odometer reading from the start of the year. We add a note that the business share is your CPA's call. We close each open month one at a time, from the oldest forward. Then the routine runs every month, so the next year end starts with clean books and a log that is kept up.
