How Much Should You Set Aside for Taxes Each Month?

The worst financial moment in freelancing is opening a tax bill that is twice what you saved. It is also the most avoidable. You just need a number, applied every time money comes in.

"I never know how much to set aside" is the most common money worry I hear from the self-employed. And the not knowing is the danger, because money that is sitting in your account feels like money you can spend. Then the bill arrives and the cushion is gone.

Let us give you a rule you can actually follow.

Why a flat guess fails

Most people pick a round number, save 20 percent, and hope. Sometimes that works. Often it does not, for two reasons.

First, tax is usually progressive. The more you earn in a year, the higher the rate on the top slice. A percentage that was fine in a slow year is too low in a good one. Second, your income is not steady, so a fixed monthly transfer either over-saves in lean months or under-saves in fat ones.

A good set-aside is not one number forever. It is a rate that tracks your actual income as the year unfolds.

A rule you can run

Here is the simple version that keeps you safe:

1. Set aside per payment, not per month. Every time an invoice clears, move the tax portion immediately, before it feels like income.
2. Use a rate, not a fixed amount. A percentage of each payment scales naturally with how much you earn.
3. Bias slightly high. It is better to get a small refund than a large bill. Over-saving is an annoyance. Under-saving is a crisis.
4. Keep it in a separate place. Out of your spending account. Money you cannot see is money you will not accidentally spend.

The exact rate depends on where you live and what you earn, so treat the figures above as a starting frame, not advice for your situation. The habit is what matters: move the money the moment it arrives.

The number that should change with you

The reason "set aside 25 percent" is only half the answer is that your real rate moves as your year-to-date income grows. Early in the year you might genuinely owe less. By a strong fourth quarter you might owe more. A static rule cannot see that. A continuous estimate can.

Let the estimate run continuously

Doing this by hand means recalculating your expected tax every time your income changes, which is never going to happen. So people fall back on the flat guess and hope.

A system that watches your income and expenses can keep a live estimate of what you owe and tell you the set-aside on each payment as it lands. That turns a vague worry into a specific instruction: this invoice was 4,000, move 1,100. No spreadsheet, no dread.

A tool like Dotio is being built to do exactly that: track what you earn, estimate what you will owe as the year goes, and tell you what to set aside as money comes in, so the tax bill never surprises you again.
