How self-employment tax works
As a self-employed dog walker, you pay two types of federal tax on your net profit (income minus deductions):
- Self-employment tax: 15.3% — this covers Social Security and Medicare contributions that an employer would normally split with you
- Federal income tax: Based on your total taxable income for the year, ranging from 10% to 37% depending on your bracket
On $50,000 net profit from dog walking: self-employment tax is approximately $7,650. Federal income tax (assuming no other income, single filer) is approximately $4,400. Total federal tax burden: approximately $12,050, or about 24% effective rate. State taxes vary by state.
The good news: you can deduct half of your self-employment tax from your taxable income, which reduces the income tax portion slightly.
Quarterly estimated payments
Unlike employees, no one withholds taxes from your dog walking income automatically. If you expect to owe more than $1,000 in federal taxes for the year, you are required to make quarterly estimated tax payments to avoid a penalty.
Payment deadlines: April 15, June 15, September 15, and January 15 of the following year.
A simple approach: set aside 25–30% of every payment you receive into a dedicated savings account. Pay from that account quarterly. This is conservative but eliminates the risk of owing a large sum at tax time.
Deductions dog walkers can take
- Mileage: Every mile driven between client walks is deductible at the IRS standard mileage rate (67 cents per mile in 2024 — check the current rate). This is often the largest deduction for dog walkers. Keep a mileage log.
- Insurance: Your dog walking insurance premium is fully deductible
- Equipment: Leashes, harnesses, waste bags, first aid kit, and any other gear used for the business
- Phone: The business-use percentage of your phone and plan
- Software: Square, scheduling apps, and any business software subscriptions
- Marketing: Business cards, Google Ads if you run them, any paid promotion
- Home office: If you use a dedicated space at home for business administration (not common for dog walkers)
What records to keep
- A mileage log — date, start location, end location, miles, and business purpose for every trip
- Receipts for all business expenses — insurance, equipment, software
- Income records — Square reports, Venmo/Zelle transaction history, bank statements
- Client invoices if applicable
Keep records for at least three years. The IRS can audit returns from up to three years ago (six years if they suspect significant underreporting).
Whether to form an LLC or S-Corp
A sole proprietorship (operating under your own name with no entity formation) is the simplest structure for a new dog walker. All income and expenses flow through your personal tax return on Schedule C.
An LLC adds liability protection — it separates your personal assets from business liabilities. For a dog walker, insurance provides most of this protection, but an LLC adds a legal layer. Most dog walkers form an LLC once they have consistent revenue, typically $30,000+ per year.
An S-Corp election can reduce self-employment taxes at higher income levels ($70,000+) but adds accounting complexity. This conversation belongs with a CPA once you reach that income level.
Consult a local accountant for advice specific to your state and situation. Tax law changes annually and state rules vary significantly.
