How to Reconstruct Your SARS Travel Logbook (The Legal Way)

It's filing season. Your accountant has asked for your logbook. You have a car, a year's worth of client visits, and absolutely nothing written down.

You are in extremely large company. Most people who receive a travel allowance don't capture their kilometres daily — they intend to, they manage it for three weeks in March, and then life happens. The good news is that a logbook you build now from real records is perfectly legitimate. The bad news is that a logbook you invent from nothing is not, and the difference matters more than most people realise.

Here's how to do it properly.

First, understand what SARS actually wants

This is the part that surprises people. A SARS-compliant logbook is far less demanding than the mental image of a notebook in the cubbyhole with an entry for every school run.

You need two odometer readings: one at the start of the tax year (1 March) and one at the end (28 or 29 February). Those two numbers give your total kilometres travelled for the year.

Then, for business travel only, you record for each trip: the date, the kilometres travelled, the destination, and the reason for the trip.

That's it. You do not have to record the detail of your private trips. Private kilometres are simply your total kilometres minus your business kilometres — a single number, not 300 rows of "shops," "gym," "mother-in-law." This is why reconstructing a logbook is achievable: the only thing you need to rebuild in detail is the business travel, and business travel leaves a paper trail.

Second, find your odometer readings

If you didn't note them, you're not sunk. Try these, in rough order of reliability:

• Service records. Every service invoice records the odometer reading and the date. Two services roughly a year apart let you interpolate with reasonable confidence.
• Licence renewal or roadworthy documentation, which often captures a reading.
• Insurance records — many insurers record annual mileage estimates or capture readings after a claim.
• Vehicle finance or trade-in valuations, which always record the odometer.
• Photographs. People photograph their dashboards more often than they think — check your camera roll around 1 March.
• Tracking or telematics apps if you have a Cartrack, Netstar or similar device fitted.

Where you're estimating between two known points, be conservative and be prepared to explain your method. An estimate you can justify is defensible. A round number you invented is not.

Third, rebuild your business travel from records you already have

This is where the work is, and where your existing digital life does most of it for you:

• Your calendar. Every client meeting, site visit and appointment with a location attached is a business trip with a date and a destination already recorded.
• Your email. Search for "see you at," "directions," "our offices" — meeting confirmations are travel evidence.
• Invoices and job cards. If you invoiced a client for work done on site, you drove there.
• Bank and fuel card statements. Fuel purchases in unfamiliar towns tell you where you were and when.
• Google Maps Timeline. If location history is switched on, this is close to a complete record of everywhere you drove, day by day, and you can export it.
• WhatsApp. "On my way" is a timestamped travel record. So is a shared live location.

Work out the distance for each recurring route once — home to your main client, office to the depot — and reuse it. Most people's business travel is not 200 unique journeys; it's five or six routes repeated across the year. Once you spot the pattern, the reconstruction goes quickly.

The line you must not cross

Reconstructing a logbook from evidence is legitimate record-keeping. Fabricating trips that did not happen is a false statement on a tax return, and the consequences run from a disallowed claim and understatement penalties through to criminal liability in serious cases.

Practically, inflated logbooks are also easier to catch than people assume. Business kilometres that account for 90% of total travel invite an obvious question about how you got to work. Claimed trips that don't match your invoicing pattern don't hold up. Distances that don't match the actual route between two addresses are checkable in seconds. If SARS selects your return for verification, you will be asked for the logbook and possibly the supporting evidence behind it — so build the thing you'd be comfortable handing over.

The honest version is usually worth more than people fear, anyway. Reconstructed properly, most people find they drove more for business than they'd have guessed.

Fourth, make the numbers reconcile

Your logbook has to balance. Business kilometres plus private kilometres must equal closing odometer minus opening odometer, exactly. If your business trips add up to more than your total distance travelled, something is wrong — and that's the single most common error in a rushed reconstruction.

The daily odometer chain also has to run continuously: each day's closing reading becomes the next day's opening reading, all the way from 1 March to the end of February. Doing this by hand in a spreadsheet is where the evening disappears.

Then keep next year's the easy way

Two habits make all of this unnecessary:

Photograph your odometer on 1 March and again on 28 February. Ten seconds, once a year, and the hardest part of the reconstruction never happens again.

Capture business trips as you go, or at least monthly while your calendar still makes sense to you.

That's exactly what we built LogBoek for. Enter your two odometer readings, add your business trips — with recurring routes handled in one entry — and it builds the full year, balances the odometer, and exports a finished, SARS-ready PDF. Whether you're catching up on a year you didn't track or starting the new one properly, it's the same 5 minutes.
