Self-Employment Tax: What Freelancers Actually Pay

Tax Moves with You When You Freelance

When you become self-employed, your employer stops withholding taxes for you. Instead, you are responsible for tracking your income and paying both income tax and, in many countries, a self-employment tax that covers contributions an employer would otherwise have made.

The Two Main Layers of Tax

The first layer is income tax on your profit—what you earn after expenses. In the US and UK this is typically progressive: higher earnings fall into higher brackets, so not every dollar is taxed at the top rate.

The second layer is self-employment or social security tax. In the US, self-employed people pay both the employee and employer shares, which is why the combined Social Security and Medicare rate can be substantially higher than for an employee. Many countries have an equivalent self-employment contribution.

Deduct Expenses First, Then Estimate the Rest

Your biggest lever is to account for legitimate business expenses before applying tax. Software, equipment, a portion of your home, travel and professional fees are all potential deductions. Estimating tax on your full revenue instead of your profit leads to overpaying unnecessarily.

Set Money Aside as You Go

A common rule of thumb for self-employed people is to set aside a percentage of every payment for taxes—often 20% to 30% depending on your income and country. Many freelancers base this on the effective tax rate from the previous year rather than face a surprise bill at filing time.

Use an Estimate Before the Numbers Land

Rather than guessing, run your gross income through a contractor tax estimate to see your likely liability, net income and effective rate across regions. Knowing the effective rate in advance helps you budget monthly cash and avoid nasty surprises.
