How do you fill out a log book example

Look, filling out a log book isn't rocket science, but get it wrong and you're in for a world of pain come tax time. Whether it's for your car, your work hours, or some training thing, the basics are pretty much the same. A log book isn't just some notebook you scribble in—it's a legal document that needs to be accurate, readable, and done on time. Let me walk you through it using the most common one: a vehicle log book for business expenses.

What are the essential parts of a log book entry?

Every single entry needs certain bits of info to actually count. For a vehicle log, you're looking at the date, what the trip was for, your odometer readings at start and finish, and the total distance. Oh, and don't forget where you started and where you ended up. Sounds obvious, right? But you'd be surprised how many people skip the addresses. A proper entry lets you figure out what percentage of your driving is business-related, which is what the tax folks care about.

Step-by-step example: Filling out a vehicle log book

Okay, let's make this real. Say you've got a company car and you're driving to see a client. Here's how the entries might look.

Date Purpose Start Location End Location Start Odometer End Odometer Total km
15 Oct 2023 Client meeting - ABC Corp Office HQ, 123 Main St ABC Corp, 456 Oak Ave 45,200 45,280 80
15 Oct 2023 Return to office ABC Corp, 456 Oak Ave Office HQ, 123 Main St 45,280 45,360 80
16 Oct 2023 Personal errand (grocery) Home, 789 Pine Ln Home, 789 Pine Ln 45,400 45,420 20

See how the first two trips are business? The third one's personal. To get your business percentage, you add up all the business kilometers (160 here) and divide by total (180). That gives you 88.9%. Simple math, but it matters a lot.

How do you handle a log book for a driver's daily log?

Commercial drivers have a different beast. It's called a driver's daily log or hours of service log, and yeah, it's a legal thing. You're tracking your duty status every 15 minutes. Seriously. You note driving hours, on-duty but not driving, off-duty, and sleeper berth time. Plus carrier name, office address, total miles. An example? Driver starts at 6 AM, drives till 10, takes a 30-minute break, then drives again from 10:30 to 2 PM. That kind of thing.

What are the most common mistakes when filling out a log book?

People mess up all the time. Biggest one? Waiting till the end of the week to fill it in. Then you're guessing odometer readings, and that's just asking for trouble. Inconsistent abbreviations or handwriting that looks like chicken scratch—yeah, that's a problem. For tax purposes, not writing the specific business purpose is a killer. "Work" doesn't cut it. And here's one everyone forgets: logging personal trips. Skip those and your business percentage is way off, which auditors love to catch.

Checklist for a perfect log book entry

  • Date recorded: Double-check you've got the right date. Sounds dumb, but mistakes happen.
  • Accurate odometer: Write down exactly what you see, not what you think it should be.
  • Specific purpose: "Client meeting" or "supplier visit." Not just "work" or "stuff."
  • Complete addresses: Street names and cities. Both start and end.
  • Total distance calculated: Do the subtraction yourself. Don't trust your gut.
  • Legible handwriting: If an auditor can't read it, it didn't happen.
  • No gaps: Every day the car moves needs an entry. Even if it's just to the store.

Frequently asked questions

Do I need to keep a log book if I only use my car for business occasionally?

Yeah, you do. Even if it's once a month, you need a log book to claim expenses. You've gotta track every trip for 12 continuous weeks to establish your business use percentage. Personal trips count too—don't skip them.

Can I use a digital log book instead of a paper one?

Sure, digital ones are fine. Tax authorities accept apps that use GPS tracking—honestly, they're probably more accurate than paper. But the rules are the same: you still need to note the purpose of each trip and be ready to show it if you get audited.

What happens if I make a mistake in my log book?

Don't panic. Just draw a single line through the error and write the correct info next to it. No white-out, no erasing. Initial the correction so it looks intentional. If you're making a lot of mistakes, that's a red flag.

How long do I need to keep my log book records?

Usually three to seven years after the tax year. Depends where you live. Check your local rules. For commercial driver logs, it's shorter—maybe six months to a year. But better safe than sorry.
