How much to save for taxes as a freelancer? The safest rule of thumb is to move 27% to 30% of every payment into a separate account the day it arrives. That is a planning number, not a tax return, and it can run higher in some states or at higher incomes. But it is a sound starting point, and the rest of this article shows where it comes from, when you actually have to pay, and how the IRS safe harbor rule protects you from penalties if you get the math slightly wrong.
Search for this question and you will find 20%, 30%, and a lot of “it depends.” Those answers are not wrong, they are just built on different incomes. Here is how to build your own.
Why freelancers pay two taxes, not one
When you work for an employer, Social Security and Medicare taxes are split between you and the company, and income tax is withheld from every paycheck. When you are self-employed, none of that happens automatically, and you owe two separate things.
Self-employment tax is the first. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It is the same money an employer would normally share with you, except now you pay both halves. It applies to 92.35% of your net self-employment earnings (what is left after business expenses), which makes the effective rate on your net profit a little lower than 15.3%. You generally owe it once your net earnings reach $400 for the year.
Federal income tax is the second, and it comes on top. It is based on your total income and your bracket, the same as for everyone else. Many states add their own income tax as well.
To see how the first one works, take an example with round numbers. Say your net freelance profit for the year is $60,000. Self-employment tax is about $60,000 × 92.35% × 15.3%, which comes to roughly $8,480, or just over 14% of your profit. Income tax is then calculated on top of that, and you can deduct half of the self-employment tax when you work out your taxable income. Put both together and many freelancers end up owing somewhere in the range of a quarter to a third of their net profit. That range is where the 27% to 30% rule comes from.
How much to save for taxes as a freelancer: the 27–30% rule
Here is the habit that makes the number useful: take the percentage out when the money lands, not at the end of the month and not when you remember. A $3,000 client payment arrives, $900 (30%) goes straight to your tax account, and you treat the remaining $2,100 as the money you can spend or reinvest.
Why 27% to 30%? It comfortably covers the 15.3% self-employment tax plus a typical federal bracket for many freelance income levels. Move it up toward 35% if you live in a state with a high income tax, such as California or New York, or if your income is pushing you into a higher bracket. If your income is low and your expenses are high, your real number may be lower. The only way to know for sure is to run your own figures or ask an accountant.
One mindset shift helps: that money was never really yours. It is tax money passing through your account on the way to the IRS. The freelancers who get into trouble are rarely the ones who do not understand this. They are the ones who understand it, then quietly borrow from the tax account during a slow month.
How much to save for taxes as a freelancer: estimated quarterly payments
Saving the money is step one. Step two is paying it. Because nothing is withheld from your income, the IRS expects you to pay as you earn, through estimated tax payments made four times a year (Form 1040-ES is the usual route).
Here is the detail that catches new freelancers off guard: the “quarters” are not equal three-month blocks. The year is split like this:
- Income earned January 1 to March 31 is due around April 15
- Income earned April 1 to May 31 is due around June 15
- Income earned June 1 to August 31 is due around September 15
- Income earned September 1 to December 31 is due around January 15 of the following year
When a due date lands on a weekend or a legal holiday, the payment is on time if you make it the next business day, so the exact dates shift a little from year to year. Check the current dates on the IRS site before you pay.
If you pay too little, or pay late, the IRS can charge an underpayment penalty. It is figured separately for each payment period, based on how much you were short, how long it stayed unpaid, and the interest rate in effect. It is not a catastrophe for most people, but it is an entirely avoidable cost.
The safe harbor rule: the safety net most freelancers miss
You do not need to predict this year’s income perfectly to avoid a penalty. The IRS gives you two main safe harbors. You generally avoid the underpayment penalty if your total payments for the year (withholding plus estimated payments) reach the smaller of:
- 90% of this year’s tax, or
- 100% of the tax shown on last year’s return
If your adjusted gross income last year was above $150,000 ($75,000 if married filing separately), the prior-year test is 110% instead of 100%. You also generally avoid the penalty if you owe less than $1,000 after withholding and credits.
For a freelancer with uneven income, the prior-year test is the useful one, because you do not have to forecast anything. Take last year’s total tax, divide it by four, and pay that amount each period. Even if this year turns out to be your biggest ever, you are protected from the penalty.
Two honest caveats. First, safe harbor protects you from the penalty, not from the bill. If you earn much more this year, you still owe the full tax when you file, so keep saving your percentage. Second, if your income arrives in lumps, the IRS also allows an annualized income method that can lower required payments in slow quarters (Form 2210 walks through it). Both are worth a conversation with a tax professional the first time you use them.
How much to save for taxes as a freelancer: keep it in its own account
The last piece is practical rather than technical. Do not leave tax money in the account you spend from, even if you are disciplined. Open a separate, boring savings account, give it a name you will not want to raid (“Not My Money” works), and set up an automatic transfer for your percentage whenever a payment comes in, if your bank allows it.
It sounds almost too simple. But separating the account is often the difference between freelancers who dread tax season and freelancers who treat it as a routine payment.
Quick answers
Do I owe self-employment tax on a small side income?
Generally yes, once your net earnings from self-employment reach $400 for the year, even if you also have a regular job. Income tax is calculated separately.
Do states have their own estimated tax payments?
Many do. Rules, forms and due dates vary by state, so check your state tax agency as well as the IRS.
How much to save for taxes as a freelancer: is 30% always enough?
No. It is a planning figure. High-tax states, higher brackets and other income can push your real number up, and large expenses can bring it down.
The bottom line
Set aside 27% to 30% of every payment when it arrives, pay on the IRS estimated tax schedule, use the safe harbor rule so you are not guessing, and keep the money somewhere you never touch. The numbers are simple once you see them laid out, and the habit does most of the work.
