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.

Payment schedules: quarterly vs self-assessment

How you pay tax depends on where you are based.

UK — Self Assessment. You file a tax return once a year by 31 January for the previous tax year (6 April to 5 April). Payment is also due 31 January. If your bill exceeds £1,000, HMRC requires you to make two payments on account — advance payments toward the following year — due 31 January and 31 July. This catches many first-year freelancers off guard: in January you pay the previous year's bill plus 50% of an estimated advance. Your 20-30% savings rate should cover both.

US — Quarterly estimated taxes. The IRS expects freelancers to pay estimated taxes four times a year. The due dates are approximately 15 April, 15 June, 15 September, and 15 January (for the fourth quarter). Missing these leads to underpayment penalties, even if you pay the full amount in April. Use IRS Form 1040-ES to calculate each payment.

Most EU countries. Quarterly or annual advance payments depending on the country and your income level. Some countries (Germany, France, the Netherlands) require advance tax payments throughout the year. Check the specific rules for your country with a local accountant.

How to calculate exactly what you owe

A rough estimate is better than nothing, but an exact calculation prevents both underpayment (penalties) and overpayment (giving the government an interest-free loan).

The calculation:

1. Total gross income — all payments received in the period
2. Minus allowable expenses — everything deductible (software, equipment, home office, travel, professional services)
3. Equals taxable profit
4. Apply your tax rate to the taxable profit, accounting for your personal allowance
5. Add self-employment tax (US only — 15.3% on net earnings, though half is deductible)

This is why expense tracking matters so much. Every £100 or $100 of deductible expenses reduces your taxable profit — and therefore your tax bill. A freelancer earning £50,000 with £8,000 of legitimate expenses pays tax on £42,000, not £50,000.

What happens if you underpay

Underpaying — whether accidentally or deliberately — has real consequences.

UK. HMRC charges interest on late payments (currently around 7.5% per year) from the due date. If you persistently underpay or file late, HMRC can also impose fixed penalties. Deliberate non-compliance leads to larger penalties based on the tax owed.

US. The IRS charges an underpayment penalty if you owe more than $1,000 at tax time and have not paid enough through estimated taxes. The penalty is calculated on the shortfall using the federal short-term rate plus 3%. It is not devastating but it is avoidable.

The practical fix: if you have a good year and your income significantly exceeded your estimate, top up your savings rate immediately rather than spending the excess.

VAT and GST: when you hit the threshold

Income tax is not the only tax freelancers face. Once your turnover exceeds a certain threshold, you are required to register for VAT (UK/EU) or GST (Australia, Canada, New Zealand).

UK. The VAT registration threshold is £90,000 (2026). Once you exceed this in a rolling 12-month period, you must register and charge VAT (20% standard rate) on your services. You also reclaim VAT on business purchases. This is complex enough that an accountant is worth the fee.

Australia. Register for GST once your turnover exceeds AUD 75,000. Add 10% GST to invoices and submit quarterly Business Activity Statements.

Canada. Register for GST/HST once your taxable supplies exceed CAD 30,000 in a single quarter or four consecutive quarters.

US. There is no federal VAT/sales tax for services. State sales tax on services varies significantly — most states do not tax B2B service income, but rules differ.

If you are approaching a threshold, plan for it. Suddenly having to charge clients an extra 10-20% on your rates can affect existing contracts.

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.

Frequently asked questions

How much tax do freelancers pay?
It varies by country and income level. In the UK, Income Tax starts at 20% above the personal allowance (£12,570 in 2026) and rises to 40% above £50,270. National Insurance adds a further 6-9% depending on your profits. In the US, freelancers pay federal income tax (10-37% depending on bracket) plus self-employment tax of 15.3% on net earnings. Most freelancers land in the 25-35% effective rate range after deductions.

Can I pay my tax bill in instalments?
In the UK, HMRC offers a Time to Pay arrangement if you cannot pay in full — you arrange a monthly payment plan before the deadline. In the US, the IRS has installment agreement options. Both options involve interest charges. The better approach is to set aside money as you earn rather than negotiating later, but instalments are available if you have not.

Do freelancers get a personal tax allowance?
Yes. In the UK, everyone gets the personal allowance (£12,570 in 2026) — you pay no Income Tax on earnings below this. In the US, the standard deduction applies (around $14,600 for single filers in 2026). Your effective tax rate on total income is lower than the marginal rate because of these allowances.

Should I register as a limited company to pay less tax?
For some freelancers, operating as a limited company (UK) or LLC/S-Corp (US) reduces the total tax burden — particularly once profits exceed £35,000-£50,000. The main mechanism is taking a combination of salary and dividends rather than all income as self-employment profit. The admin overhead is higher and you should get professional advice before incorporating. It is not always worth it at lower income levels.
