How to Track Freelance Income and Expenses in 2025

If you're freelancing, you're running a business. And every business needs to track its money. But here's the problem: most freelancers either use scattered spreadsheets, forget to track expenses, or worse—dump everything in a shoebox until April.

In this guide, you'll learn exactly how to track your freelance income and expenses like a pro—without spending hours on bookkeeping.

Why Tracking Matters (Beyond Taxes)

Yes, you need records for the IRS. But tracking your finances gives you something more valuable: clarity.

Know if you're actually profitable (revenue ≠ profit)
Spot trends in your income (seasonal dips, best clients)
Make informed decisions about raising rates or cutting expenses
Calculate your true hourly rate (including admin time)

The Simple System for Tracking Freelance Income

Step 1: Separate Business and Personal

Open a dedicated business checking account. Every client payment goes here. Every business expense comes from here. This single step eliminates 80% of bookkeeping confusion.

Step 2: Record Income When It's Received

For each payment, track:

Date received
Client name
Project/invoice number
Amount
Payment method

Step 3: Categorize Expenses Immediately

The biggest mistake? Waiting until tax time to categorize. Spend 5 minutes a week categorizing expenses while you remember what they were for.

Common freelancer expense categories:

Software & subscriptions - Tools of your trade
Office supplies - Even your home office counts
Professional development - Courses, books, conferences
Marketing & advertising - Website, ads, business cards
Travel - Client meetings, conferences
Home office - Percentage of rent/utilities

How Much Should You Set Aside for Taxes?

The general rule: 25-30% of every payment. This covers:

Federal income tax
Self-employment tax (15.3%)
State income tax (if applicable)

Transfer this percentage to a separate savings account immediately when you get paid. Out of sight, out of mind—and you'll never be caught short in April.
