How To Calculate Quarterly Taxes For Self Employed Workers
Written by 1099 Tax Guide Team
Educational resources designed to help freelancers, contractors, and independent workers understand tax concepts.
Many self-employed workers receive income without traditional payroll withholding. Because of this, they often need to estimate and plan their own tax payments.
Learning how to calculate quarterly taxes can help freelancers understand their financial obligations throughout the year.
What Are Quarterly Taxes?
Quarterly taxes are estimated payments made during the year for income taxes and self-employment tax.
Instead of waiting until the end of the year, many self-employed workers make payments throughout the year.
Who Needs To Calculate Quarterly Taxes?
Quarterly tax planning is commonly associated with:
- Freelancers
- Independent contractors
- Consultants
- Small business owners
- Online creators
How Quarterly Taxes Are Calculated
A basic quarterly tax estimate usually starts with understanding income, expenses, and expected tax responsibilities.
Step 1: Estimate Your Annual Income
The first step is estimating how much money you expect to earn during the year. For freelancers and contractors, this may include payments from clients, projects, or business activities.
Example
If a freelancer expects to earn approximately $80,000 during the year, that amount becomes the starting point for a tax estimate.
Step 2: Estimate Business Expenses
Self-employed workers often track expenses related to their business activities. These expenses may affect the amount of income subject to taxes.
- Office expenses
- Software subscriptions
- Equipment costs
- Marketing expenses
- Professional services
Step 3: Calculate Self Employment Tax
One important part of quarterly tax planning is understanding self-employment tax.
Unlike many employees who have payroll taxes automatically withheld, self-employed workers generally manage these payments themselves.
Step 4: Estimate Income Tax
After estimating business income and expenses, workers can review possible income tax obligations.
Income tax estimates depend on factors such as:
Income
Higher income levels may affect overall tax calculations.
Deductions
Eligible deductions may affect taxable income.
Filing Situation
Personal circumstances may influence tax estimates.
Step 5: Divide Estimated Taxes Into Payments
After estimating yearly taxes, many workers divide the amount into quarterly payments.
Simple Example
Estimated yearly tax:
$12,000
Divided into four estimated payments:
$12,000 ÷ 4 = $3,000 per payment
Quarterly Tax Payment Deadlines
Self-employed workers usually make estimated payments during several periods throughout the year.
| Payment Period | General Timing |
|---|---|
| First Quarter | Spring payment period |
| Second Quarter | Summer payment period |
| Third Quarter | Fall payment period |
| Fourth Quarter | Following year payment period |
Common Quarterly Tax Mistakes
Not Saving Money For Taxes
Some freelancers spend all income received and forget to reserve money for taxes.
Using Old Income Estimates
Income changes throughout the year, so estimates may need updates.
Ignoring Business Expenses
Poor expense tracking can make tax planning less accurate.
Tips For Better Quarterly Tax Planning
- Review income every month
- Keep business records organized
