Freelancer Tax Calculator (1099)

How freelancer and 1099 taxes work

As a freelancer you pay two kinds of federal tax on your profit: self-employment tax (Social Security + Medicare — 15.3%, since you cover both the employee and employer halves) and ordinary income tax. Because no employer withholds for you, the IRS expects quarterly estimated payments. This calculator estimates all of it and splits your bill into four payments.

How this is calculated

Self-employment tax is 15.3% on 92.35% of your net profit (12.4% Social Security up to the annual wage base, plus 2.9% Medicare with no cap). Half of that SE tax is deductible, so we subtract it (and your standard deduction) to get taxable income, then apply the federal brackets for your filing status. An optional flat state rate and other income can be added. The total is divided into four equal quarterly payments (due mid-April, mid-June, mid-September, and mid-January).

This is a simplified estimate using the latest published brackets — it ignores credits, the QBI deduction, and many state specifics. It is not tax advice; confirm with a tax professional. See our disclaimer.

The two taxes freelancers pay

When you work for yourself, your income is generally taxed in two separate ways. The first is self-employment tax, which covers your Social Security and Medicare contributions. When you have an employer, those amounts are split between you and the company; as a freelancer you typically cover both halves yourself. The second is regular income tax, the same kind of tax most people pay on what they earn. This calculator estimates both so you can see your likely total. Treat the result as an approximate planning figure, not an exact bill.

How quarterly estimated taxes work

A traditional paycheck has taxes withheld automatically. Freelance income usually has no withholding, so the tax system generally expects you to pay as you go through quarterly estimated taxes. There are typically four payment periods each year, with deadlines that generally fall around mid-April, mid-June, mid-September, and mid-January of the following year.

Many people aim for a "safe harbor" by paying in roughly what they owed the prior year (or a reasonable estimate of the current year), which can help avoid an underpayment situation. The exact rules and percentages change over time, so confirm the current details with a tax professional before relying on them.

A simple set-aside example

An easy habit is to move a slice of every payment into a separate savings account the moment it lands, rather than scrambling at deadline time. A common rule of thumb is to set aside roughly a quarter to a third of your profit (income after business expenses).

Suppose you expect around $60,000 in net profit for the year. Setting aside about 30% means parking roughly $18,000 for taxes, or about $4,500 each quarter. If you keep that money in a dedicated account, you can even earn a little interest while it waits. Our savings goal calculator can help you plan steady transfers toward that target.

Deductions to track

Ordinary and necessary business costs can generally reduce the profit you are taxed on, which is why good records matter. Common categories freelancers track include:

• Home office — a dedicated workspace used regularly for business
• Equipment — computers, cameras, tools, and similar purchases
• Software and subscriptions — apps and services you use to do the work
• Mileage and travel — business driving and trips, with logs to back them up
• Health insurance — premiums that may qualify for self-employed individuals

Keep receipts and notes for everything, and confirm eligibility, since the rules around each category have specific requirements.

Common mistakes to avoid

• Forgetting self-employment tax — budgeting only for income tax and getting surprised by the rest
• Not saving as you go — spending everything and having nothing set aside at deadline time
• Mixing personal and business money — making it hard to track real expenses and deductions
• Missing quarterly deadlines — which can lead to penalties or interest

Every situation is different, so use these estimates as a starting point and confirm your specifics with a qualified tax professional.
