A simple tax set-aside system that actually works

The single biggest financial stress for freelancers is the tax bill that arrives when you have already spent the money, not irregular income itself. The fix is embarrassingly simple: separate tax money the moment it arrives.

The core rule

The percentage depends on your country and income level. In the UK, 25-30% is a safe starting point for most freelancers. In the US, 25-35% covers federal income tax and self-employment tax for most brackets.

Why a separate account matters

If tax money sits in your main account, you will spend it. Your brain treats visible money as available money. A separate account breaks that connection.

Open a basic savings account at your existing bank. No fancy fintech needed. Name it "TAX" so it is unmistakable. Set up a standing order if your invoicing is regular, or do it manually each time a payment arrives.

“I started putting 30% aside from every invoice two years ago. First tax season after that was the least stressful of my life. It felt like the bill was already paid.”

What percentage to use

• UK freelancers earning under £50k: 25% is usually safe
• UK freelancers earning £50-100k: 30% to cover higher rate
• US freelancers: 30% covers federal + self-employment for most
• If in doubt, round up, a tax refund is better than a tax bill

The quarterly check

Once a quarter, compare your set-aside total against a rough tax estimate. If you are over, you have a buffer. If you are under, bump your percentage up by 5%. This takes 10 minutes and prevents year-end surprises.

Tools like FreelanceVault can automate this calculation, showing you exactly how much belongs to tax versus what is genuinely yours to spend.
