How to Set Aside Money for Quarterly Taxes as a Freelancer
Not tax advice: this post is for general education only. Check current rules and due dates on IRS.gov, or talk to a tax professional about your own situation.
When you leave a salaried job, the paycheck isn't the only thing that disappears. So does the automatic tax withholding. Clients usually pay freelancers the full invoice amount, and it's up to you to send the IRS its share during the year. Most US freelancers do this with quarterly estimated payments. The hard part is rarely the payment itself. It's having the money there when the due date comes.
This guide is about that habit: a simple, repeatable way to set money aside so tax season doesn't sting.
Why "I'll deal with it in April" goes badly
Freelance income is lumpy. A big project pays out in March, things are quiet in May, and two clients pay late in August. If taxes come out of whatever is in your checking account on the due date, you end up paying from a good month's savings during a bad month, or not paying at all.
The fix is to separate the money as it comes in, so your checking balance shows what's actually yours to spend.
Step 1: Open a separate "tax" savings account
Keep your set-aside somewhere you won't spend it by accident. A separate savings account, ideally at a different bank from your main checking account, adds just enough friction. Name it something obvious, like "TAXES – DO NOT TOUCH."
You don't need anything fancy. What matters is that the balance is out of sight in your everyday banking app.
Step 2: Choose a set-aside percentage
Every time a client pays you, move a fixed percentage into the tax account. The right percentage depends on your income, your state, your deductions, and whether you have other income, so this post won't tell you what yours should be. Some ways to land on a starting number:
- Look at last year's return. Divide your total tax by your total self-employment profit to get a rough effective rate.
- Use a tax professional's estimate. A one-time consultation is often worth it in your first freelance year.
- Use the IRS's own worksheet. Form 1040-ES includes one for estimating what you'll owe.
Whatever you choose, write it down and use it every time. A consistent percentage beats a perfect one you only apply some of the time.
Step 3: Set aside from profit, then check against reality
You're generally taxed on profit, meaning income minus business expenses, not gross revenue. That's why tracking expenses matters for taxes too. Many freelancers keep it simple by setting aside from every payment that comes in, which builds in a cushion, and then compare their set-aside with their actual profit once a month.
A monthly check takes about ten minutes:
- Total the income you received this month.
- Total your business expenses.
- Subtract to get profit.
- Multiply profit by your set-aside percentage.
- Compare that number with what you actually moved into the tax account, and top up if you're short.
Step 4: Put the quarterly due dates on your calendar
The IRS splits estimated payments into four periods, but they aren't evenly spaced calendar quarters. Due dates typically fall in mid-April, mid-June, mid-September, and mid-January of the following year, and they move when a date lands on a weekend or holiday. Look up the current year's dates on IRS.gov and add all four to your calendar, with a reminder a week ahead of each.
When a reminder fires, open your tracking sheet, check how much you've set aside for that period, and make your payment through the official IRS payment options. Don't forget your state if it has its own estimated tax.
Step 5: Keep a record of every payment
Write down the date, amount, and confirmation number for every estimated payment you make, federal and state. You'll need those totals when you file your annual return, and a confirmation number saves a lot of stress if a payment ever goes missing.
A simple tracking layout
You can do all of this with a basic spreadsheet. A layout that works:
| Quarter | Income | Expenses | Profit | Set-aside % | Set-aside amount | Paid | Date paid |
|---|---|---|---|---|---|---|---|
| Q1 | =Profit × % | ||||||
| Q2 | |||||||
| Q3 | |||||||
| Q4 |
The income and expense columns can pull from your invoice and expense logs, so the quarterly numbers fill in on their own.
If you'd rather not build it yourself, TallySheet is a $19 spreadsheet that includes this kind of Quarterly Tax Estimate tab alongside invoice and expense tracking. You enter your percentage, and it multiplies your profit by it for each quarter. It doesn't calculate what you actually owe, so you still check the numbers against IRS.gov or your tax professional.
Common mistakes to avoid
- Spending the set-aside "temporarily." If you borrow from the tax account, write down when you'll pay it back and treat it like a bill.
- Forgetting late-paying clients. Track money when it actually arrives, not when you send the invoice.
- Skipping the expense log. Without expenses you can't see your true profit, and you may set aside more or less than you need.
- Setting it and forgetting it. Look at your percentage again mid-year if your income changes a lot.
- Not keeping receipts. Store receipts digitally in a folder per year, named by date and vendor.
The habit that matters
Quarterly taxes feel intimidating mostly because they arrive as a surprise. Move a fixed percentage each time you're paid, check it monthly against profit, put the due dates on your calendar, and log every payment. After two or three quarters it becomes routine.
