As a self-employed person, you're responsible for:

- Income Tax: Based on your total income and tax bracket
- State/Local Taxes: Varies by location

Tracking Income from Invoices
For tax purposes, track:
- Total invoices sent
- Total payments received (your actual income)
- Outstanding invoices (accounts receivable)
- Bad debts (uncollectible invoices)
Note: Most self-employed individuals use cash basis accounting, meaning you report income when received, not when invoiced.

1099 Forms: What You Need to Know
Receiving 1099s
Clients who pay you $600+ in a year should send you a 1099-NEC by January 31. However, you must report ALL income on your tax return, even without a 1099.
Sending 1099s
If you pay contractors $600+ in a year, you must send them a 1099-NEC. This doesn't apply to payments made to corporations or via credit card (those are reported by the payment processor).
Record Keeping Best Practices
- Keep all invoices organized by date and client
- Save receipts for all business expenses
- Use accounting software or spreadsheets to track income and expenses
- Reconcile bank statements monthly
- Keep records for at least 7 years
- Back up digital records
- Separate business and personal finances
Quarterly Estimated Taxes
If you expect to owe $1,000+ in taxes, you must pay quarterly estimated taxes to avoid penalties:
- Q1: Due April 15
- Q2: Due June 15
- Q3: Due September 15
- Q4: Due January 15 (following year)
A good rule of thumb: set aside 25-30% of each invoice payment for taxes.
When to Get Professional Help
Consider hiring an accountant or tax professional if:
- You're new to self-employment
- Your income exceeds $50,000
- You have complex situations (international clients, multiple businesses)
- You're unsure about deductions
- You've been audited before
- You want to save time and reduce stress

What business expenses can I deduct as a self-employed person?
You can deduct ordinary and necessary business expenses such as home office costs, equipment, supplies, software subscriptions, professional services, vehicle expenses, and marketing costs.

How do I calculate self-employment tax?
Self-employment tax covers Social Security and Medicare taxes and is calculated at 15.3% on 92.35% of your net self-employment income. You can deduct half of your self-employment tax as a business expense when filing your taxes.
What invoicing records should I keep for tax purposes?
Keep copies of all invoices sent to clients, payment receipts, bank statements, and expense records for at least three to seven years. These documents provide proof of income and expenses if the IRS audits your tax return and help you accurately report your self-employment income.
