What percentage of my paychecks should I be setting aside for taxes?

No one tells you what percentage to set aside for tax when you're self-employed. Here's how a tax pot works, and why the habit matters more than the perfect number.

What you need to know

  • There is no single percentage that works for every self-employed person in every country. Your tax situation depends on where you live, how much you earn, and your business structure. A qualified accountant or tax professional can give you the actual number for your situation.
  • What you can do right now, today, is set up a tax pot: a separate place where a slice of every payment you receive goes the moment it lands.
  • The habit of moving money aside is more protective than knowing the perfect percentage. The pot makes tax visible, so the bill stops being a shock.

If you woke up this morning with that low hum of money panic in the background, this is for you.

Not the loud panic. The quiet one. The one that just sits there while you get on with client work and answer emails and try not to think too hard about what is sitting in your account.

A lot of self-employed people earn well. Genuinely well. And still feel like the money is gone before they can explain where it went. The tax bill arrives and it feels like a punch because nothing was set aside. Not because they were careless. Because nobody built a system for them the way an employer would have.

So. This post is about that system. Specifically the tax pot, why it works, and what to do today.

The quick answer

There is no universal percentage that fits every self-employed person. Tax rates vary by country, by income level, and by business structure. What this post gives you is the behaviour: move a slice aside when money lands, every time, without waiting to know the exact amount. Then speak to a qualified tax professional about the right figure for your situation.

What you might be telling yourself

“I dread tax season every single year.” That dread is information. It is telling you that tax is arriving as a surprise, and surprises feel like threats.

“The more money I make, the more money I owe.” Yes, and that is actually how it is supposed to work. The money to pay the bill has already left by the time the bill arrives. That is the gap the tax pot closes.

“I have been blowing all of it and not even leaving enough to pay taxes.” That is a systems problem, not a character problem. Nobody set up a holding place for that money, so it got spent. That is what happens without a structure.

“Today I just found out I owe taxes and had no idea.” This one hits hard. The tax was always owed. It just wasn’t visible until it was.

“I just want to get a paycheck and go home. I don’t want to worry about the business.” That is a completely reasonable thing to want. The whole point of the tax pot is that it removes one layer of that worry from your plate.

“Some months I have to empty my business account to pay all the bills.” When money comes in lumps and goes out all at once, there is no natural moment to earmark a slice for tax. Building that moment in on purpose is the whole game.

Why this hits harder when you run your own business

When you work for someone else, tax disappears before you see it. The employer handles it. The number in your account is already yours.

When you run your own business, the full amount lands. All of it, in one go. And it feels like yours. So you spend it like it is.

But some of that money was never yours. It belongs to your tax authority. The government just lets you hold it for a while before they ask for it back. The asking comes later, sometimes months later, sometimes more, and by then the money is long gone.

Add to that the fact that income swings. A great month feels abundant. A lean month feels frightening. So in a great month you breathe out and loosen up, and in a lean month you pull from wherever you can. The tax money gets caught up in both.

And if business and personal spending are running through the same account, right, it is almost impossible to see what is what.

A scene you might recognise

An invoice gets paid. You see the number land in your account and for a moment things feel okay. You pay a supplier, cover a household bill that has been sitting there, maybe buy something you have needed for months. Then a smaller month comes. Then tax time. And you are doing the maths backwards, trying to figure out where it went.

When you can’t see which money is for tax and which is yours to spend, the tax money disappears quietly into everything else. Visibility is the fix.

What happens to the money once it arrives

This is the part most people don’t see, and it is the most important part.

When money lands in your account, it has already been split. Some is yours for operating costs. Some is yours to pay yourself. And some belongs to the tax authority. The trouble is, without a system, it all looks the same. It is just one number.

A tax pot changes that. The moment a payment arrives, you move a slice, say whatever percentage you and your accountant have agreed on, into a separate account. Not at the end of the month. Not when you remember. Right then.

That account does one thing: it holds tax money. You do not touch it for anything else. When the bill arrives, the money is already there.

And honestly? That is the whole system. It sounds almost too simple. But it is the thing that takes the shock out of tax season.

The behavioural ideas behind it

So why doesn’t everyone already do this? Because knowing what to do and actually doing it are two different things, and a few well-studied ideas explain the gap.

Mental accounting is a concept from Richard Thaler, who won the Nobel Prize for his work on it. We treat money differently depending on which mental pot it sits in. When everything is in one account, the brain reads it all as available. When money is in a separate account labelled “tax”, it stops feeling spendable. The physical separation creates a psychological one.

Earmarking, studied by Dilip Soman and Amar Cheema, builds on this. When money is specifically designated for something, we are less likely to spend it on other things. A tax pot is earmarked money. The label does real protective work.

Implementation intentions, a concept developed by psychologist Peter Gollwitzer, are if-then plans. Instead of “I will save for tax”, you decide in advance: “When a payment lands, I will move X% to my tax account that same day.” Research on implementation intentions shows that the specific trigger makes the behaviour much more likely to actually happen. The rule runs before you even have to think about it.

And then there is the ostrich effect, named by Galai and Sade. We avoid information that feels threatening. The tax bill feels threatening, so we don’t look, don’t plan, don’t set aside. The tax pot flips this: it makes the threatening thing visible and manageable in small pieces, so avoidance doesn’t get a foothold.

One thing to try today

Open a separate account. Today if you can. Label it “Tax” or “Tax Pot” or whatever makes it clear. If you already have one, go and check what is in it right now.

Then write this down before you close this page, somewhere you will see it:

“When a payment lands, I move [X]% to the tax account the same day.”

Leave X blank for now if you do not know the number. Talk to your accountant. But get the account open and the rule written. Because the moment the if-then plan exists, the behaviour has something to run on.

Questions people ask

What percentage of income should I set aside for tax when self-employed?

There is no one answer because tax rates vary by country, income level, and business structure. A qualified accountant or tax professional in your country is the right person to give you a specific percentage. What matters behaviourally is that you move something aside the moment money lands, every time, rather than trying to calculate perfectly and acting later.

How does a tax pot work for freelancers?

A tax pot is a separate account that holds only money set aside for tax. When a payment arrives in your main account, you transfer an agreed percentage straight into the tax pot. You do not touch that account for anything else. When your tax bill comes, the money is already sitting there waiting. It removes the shock.

Why do I always get a tax bill I can’t pay?

Usually because the money that was owed for tax got spent in the months between earning it and the bill arriving. This is extremely common when you are self-employed and income lands in one lump. A tax pot, set up so money moves the day it arrives, is the most straightforward way to stop it happening again.

Is it bad that I don’t know what percentage of tax I owe as a self-employed person?

No, it is very common. Tax for self-employed people is more complicated than for employees because nobody calculates it for you in advance. Speak to a qualified tax professional in your country to get your number. In the meantime, start moving something aside so at least some money is protected.

Can I set up a tax pot even if my income is inconsistent?

Yes, and inconsistent income makes it more important, not less. Because a percentage scales automatically, a lean month means a smaller transfer and a good month means a larger one. You do not need a steady income for a tax pot to work. You just need the rule: when money lands, a slice moves.
