Common Gig Worker Mistakes

A lawn care client came in the second week of February. He’d been running his business for three years. Nice guy. Good businessman by all accounts — his customers liked him, he had steady work, he made decent money.

His recordkeeping was a disaster.

No mileage log. No expense tracking. A shoebox with maybe 30% of his receipts. No record of which customers paid him by app versus cash. He estimated “somewhere around $40,000” in gross revenue.

The preparer spent two hours reconstructing what she could. At the end, the client owed $4,800 — mostly because without documentation, many of his expenses couldn’t be claimed with confidence. With proper records, his bill would probably have been around $2,200.

He paid $2,600 in unnecessary taxes because he didn’t keep records. That’s the lesson.

Gig workers are busy people. They’re running their business, doing the work, finding the next job. Bookkeeping is the last thing on their mind. As a preparer, you will see the same recordkeeping mistakes over and over. Knowing what they are — and knowing how to help clients avoid them going forward — is part of the job.

This is the single most expensive mistake most service-based gig workers make. At 70 cents a mile, a client who drives 20,000 business miles has a $14,000 deduction. A client with no mileage log, who can only reconstruct 8,000 miles credibly, loses $8,400 in deductions — and pays an extra $1,200+ in taxes as a result.

The fix is simple: a mileage tracking app takes about 30 seconds per day to use. MileIQ, Everlance, Stride, or a basic notepad. Every business drive logged as it happens. A full year of logs is bulletproof documentation.

When a client uses one bank account and one credit card for both personal and business expenses, every transaction has to be sorted manually at tax time. The client can’t remember which Home Depot purchase was business supplies and which was personal home repairs. The fuel receipt could be for the work truck or the family car.

The best practice — which you should recommend to every self-employed client — is a dedicated business bank account and a dedicated business credit or debit card. Everything business-related goes through those accounts. The statement becomes the record. No sorting required.

We covered this in Lesson 5, but it’s worth naming as a specific mistake. Every year, clients arrive in February having made zero estimated payments and facing a bill of $3,000, $5,000, or more. Some of them don’t have the money. Some of them have to set up payment plans. All of them would have been fine if someone had explained quarterly estimates after their first self-employment return.

Covered in Lessons 2 and 3, but worth reinforcing as a specific mistake: clients frequently believe that income with no form attached is somehow exempt. A lawn care operator who did $8,000 in cash jobs and received no 1099 from any of them still has $8,000 in self-employment income. Period.

Related but distinct: some clients not only don’t report cash income, they genuinely don’t know how much they made in cash because they never wrote it down. A client who stuffed cash in their pocket after every job and spent it without depositing it has no record and no way to reconstruct it. This is the hardest situation to deal with at tax time.

The fix: a simple notes app on the phone. After every cash job, type the amount and the client name. Five seconds of work. At year-end, a running total of every cash job is available in the phone.

A client claims 100% business use of their truck. The truck is also the family vehicle used for school pickups, grocery runs, and weekend trips. This is a common overreach that creates problems if ever examined. The mileage log that shows only business miles — with zero personal miles all year — is not credible.

Help clients understand that partial business use is legitimate and defensible. An honest 65% business use claim backed by a reasonable mileage log is far better than a 100% claim with no documentation.
