How Much Should Freelancers Set Aside for Taxes?

Tax season should not be a surprise. But for most freelancers, it is.

The invoice gets paid, the money lands, and it all feels like income. The problem is that a chunk of it was never really yours — it belongs to the tax authority, and they will come for it whether you saved it or not.

The freelancers who never stress about tax bills are not smarter or more organised. They just have a simple rule they follow every single time money arrives. This post explains that rule, why it works, and how to make it automatic.

Why freelancers get caught out

Employees never see their tax bill because their employer handles it before the money reaches them. Freelancers get the full amount first, and the responsibility to set the right portion aside.

Without a system, it is easy to spend it. Money sitting in your account feels available. Three months later, a quarterly tax bill arrives and the cash is gone — spent on living expenses, equipment, or a quieter month when income was low.

This is the single most common financial mistake freelancers make. And it is entirely preventable.

The simple rule: set aside 20-30%

The most widely used rule for freelancers is to set aside 20-30% of every payment the moment it arrives.

The exact percentage depends on where you live and how much you earn, but as a starting point:

UK freelancers: 20-25% covers Income Tax and National Insurance for most income levels. Higher earners (above £50,270) should use 40-45%.
US freelancers: 25-30% covers federal income tax plus self-employment tax (15.3%). State tax varies.
EU freelancers: Varies widely by country — 20-30% is a reasonable baseline in most markets.

When in doubt, save more, not less. Getting a refund is a pleasant surprise. Getting an unexpected bill is not.

How to make it automatic

The best tax savings system is one that requires no willpower.

Open a separate account just for tax. Call it "Tax" or "HMRC" or whatever makes it feel off-limits. Every time a payment arrives, transfer your percentage immediately — before you spend anything else.

Set a calendar reminder for each quarter. In the UK, Self Assessment payments are due January 31 and July 31. In the US, estimated taxes are quarterly: April, June, September, and January. Mark these dates now so they are never a shock.

Log every expense as it happens. Every legitimate business expense reduces your taxable income — which means your tax bill shrinks.

What counts as a tax-deductible expense?

This varies by country, but the general principle is the same: expenses that are wholly and exclusively for your business are deductible.

Software and subscriptions — design tools, project management apps, accounting software
Equipment — laptop, monitor, camera, microphone
Home office — a portion of rent, utilities, and broadband if you work from home
Professional development — courses, books, conferences relevant to your work
Client-related costs — travel to client meetings, meals where business is discussed
Professional services — accountant fees, legal advice

Every expense you miss is money you overpay in tax. Tracking them takes seconds if you have a system.

The bottom line

Set aside 20-30% of every payment the moment it arrives. Keep it in a separate account. Log your expenses so your bill is as small as it legally can be.

That is the entire system. Follow it consistently and tax season becomes just another date on the calendar — not a crisis.
