Why independent contractors track time at all
No federal law says a correctly classified independent contractor must record start and end times. The FLSA recordkeeping rules bind employers, not self-employed workers.
But you need time records for three reasons that matter more than legal compliance.
Billing. Most contractors bill by the hour or by the engagement. If you bill hourly, your invoice is only as good as your time log. A client who sees "32 hours" with no breakdown will ask questions. A client who sees a day-by-day log with task notes pays faster.
Taxes. The IRS allows independent contractors to deduct business expenses. But the home office deduction, one of the most common, requires you to know how much time you spend working from that space. If you use part of your home "exclusively and regularly" for business, the IRS wants to see a log showing you actually work there. No log, no deduction.
Legal protection. This is the reason most self-employed workers miss. If you are ever audited by the IRS or state tax agency, or if a client disputes your classification, your time records become evidence. A freelancer who cannot show when and where work happened looks like an employee being paid off the books. The Department of Labor and many state agencies examine time records when deciding if someone is misclassified.
How contractor time tracking differs from employee timekeeping
The difference is not the tool. Both groups can use the same app, the same spreadsheet, or the same paper log. The difference is the purpose and the rules.
Employees track for the employer
An employee's time record belongs to the employer. The employer sets the clock-in policy, the rounding rules, the break deductions, and the pay period. The employee is subject to the employer's system. If the employer uses quarter-hour rounding under the 7-minute rule, the employee's 8:03 AM punch becomes 8:00 AM. The employee does not get to decide.
Freelancers track for themselves
A self-employed worker's time record belongs to them. You decide what counts as billable time. You decide how to round. You decide whether to include the 15-minute phone call that turned into 40. The client can reject your invoice, but they cannot impose a rounding policy on you unless your contract says so.
This is the mental model to hold: an employee's time card is a record of what the employer required. A freelancer's time log is a record of what they delivered.
What counts as "hours worked" is different
For employees under the FLSA, "hours worked" includes time the employer "suffers or permits" the employee to work. That includes waiting time, on-call time, and certain travel time. The Portal-to-Portal Act carves out commuting and some pre-shift activities, but the general rule is broad.
For freelancers, "hours worked" means whatever your contract says it means. If you agree to bill for "all time spent on engagement tasks," that includes research, calls, and revisions. If you agree to bill for "deliverables only," you might not track hours at all. The contract defines the work. Your time log proves you did it.
What should an independent contractor actually log?
Track these things for every work session:
- Date
- Start time and end time
- Client or engagement name
- Task or deliverable
- Total hours in decimal format
Skip these things:
- Personal breaks (lunch, coffee, bathroom). Do not bill for them.
- Time spent thinking about the engagement while doing something else. If you are not actively working, it is not billable.
- Time spent on admin that you choose not to bill. Many self-employed workers eat the cost of invoicing and email management.
The rule of thumb: if you would not put it on an invoice, do not put it in your log.
How do independent contractors convert clock time to decimal hours?
Clients and accounting software usually want hours in decimal format. 7 hours and 45 is 7.75 hours, not 7.45. Use these common conversions:
- 5 = 0.08 hours
- 10 = 0.17 hours
- 15 = 0.25 hours
- 20 = 0.33 hours
- 30 = 0.50 hours
- 45 = 0.75 hours
For exact conversions, divide by 60. 7 divided by 60 is 0.1167 hours. 13 divided by60 is 0.2167 hours. Most billing systems round to two decimal places, so 0.1167 becomes 0.12.
Use a decimal hours converter to avoid arithmetic errors.
What is the biggest time tracking mistake independent contractors make?
The most common mistake is tracking time only when you remember to. You finish a task, look at the clock, and estimate. "That took about three hours." Three hours later, you realize it was actually four and a half.
The fix: start a timer or note your start time the moment you begin. Do not rely on memory. Untracked time routinely averages 15 to 20 percent undercounted. That means you are leaving money on the table every week.
When do independent contractors need formal time tracking vs. simple logging?
If you have one or two clients and bill by the engagement, a simple spreadsheet is enough. Log the date, the engagement, and the hours. Send an invoice. Done.
If you have multiple clients, bill hourly, or work on retainer, use a dedicated time tracker. Look for one that lets you tag hours by client and engagement, generate reports, and export to your invoicing software. Free tools exist. The key is consistency, not features.
If you bill by the deliverable rather than the hour, you still need to track time for yourself. You need to know if an engagement that paid $2,000 took 20 hours or 40 hours. That information tells you which clients are profitable and which are eating your margins.
When should independent contractors skip minute-by-minute tracking?
The default advice says "track every minute." That is right for most self-employed workers. But if you charge flat fees for defined deliverables and your clients never question your invoices, you can track time for your own purposes without billing by the hour. Track enough to know your effective hourly rate. If an engagement takes twice as long as expected, raise your flat fee next time.
The people who should ignore the "track everything" advice are those who work on commission or per-piece pricing. A real estate agent who gets paid at closing does not need to log hours. A graphic designer who charges $500 per logo does not need a minute-by-minute log. Track only what you need to set your prices and prove your work.
But for everyone else billing hourly or by the engagement: track every session, convert to decimal, and protect yourself with a record that belongs to you. It is not about the client. It is about your business.
