Figuring out how much to save for freelance taxes is one of the first real financial decisions freelancers face, and most people get it wrong by defaulting to generic advice. The percentage you’ve seen most often — “set aside 25–30%” — is not wrong, exactly. It’s just calibrated for a specific type of freelancer at a specific income level in a specific country. For everyone else, it’s an approximation that can leave you thousands short when the bill arrives.
The good news: the actual calculation isn’t complicated. You just need to do it for your situation, not someone else’s.
Why “Save 25–30%” Doesn’t Answer How Much to Save for Freelance Taxes
The “save 25–30%” rule comes mostly from US-centric financial advice, and it’s built around the self-employment tax rate (15.3%) plus a federal income tax estimate in the 22–24% range. That math roughly works for a US-based freelancer earning $60,000–$80,000 per year.
If you’re in the UK, Germany, the Netherlands, or Australia, the underlying numbers are different. If you’re at a higher income level, your marginal rate is higher. If you have significant deductible expenses, your taxable income is lower than your gross. The one-size advice abstracts over differences that translate into real money.
A freelancer earning £80,000 in the UK, setting aside 25%, is provisioning £20,000. Their actual combined income tax and National Insurance liability on that income is closer to £28,000. That’s an £8,000 gap, roughly what a competent accountant charges for four years of work.
The Calculation: Two Components
Your total set-aside covers two things, which you need to estimate separately.
Income tax is calculated on your taxable income, that is, your gross earnings minus allowable business expenses. Find your country’s current marginal rates and brackets. Estimate your annual taxable income (conservatively, assume income on the higher end of what you expect). Calculate the income tax owed at that income level. Divide by total gross income to get your income tax percentage.
Social contributions are separate. In the US, self-employment tax is 15.3% on net self-employment income up to the Social Security wage base (around $160,000 in 2024), then 2.9% above that. In the UK, Class 4 National Insurance is 6% on profits between £12,570 and £50,270, and 2% above that. In Germany, social contributions depend on your health insurance arrangement and can be substantial, often 15–20% of income. Know your country’s structure and add it to your income tax percentage.
The sum of those two estimates is your set-aside rate. Apply it to gross income received, not net profit, because gross is what you can easily measure in real time.
What the Rates Look Like in Practice
These are rough estimates, not precise calculations — verify with a local accountant or official calculator for your jurisdiction.
At an income equivalent of $50,000/year:
- US: Approximately 27–30% combined (income tax + self-employment tax, with partial SE tax deduction)
- UK: Approximately 25–28% combined (income tax above personal allowance + Class 4 NI)
- Australia: Approximately 28–32% combined (income tax + Medicare levy + optional super contributions)
- Germany: Approximately 35–40% (income tax + health/pension contributions for self-employed)
At $80,000/year:
- US: Approximately 30–33%
- UK: Approximately 32–36%
- Australia: Approximately 34–38%
- Germany: Approximately 38–44%
The pattern is consistent: as income rises, the effective rate rises. At $80,000, 25% is short in most high-income countries. 30% is more defensible but still tight in several jurisdictions. 35% is a reasonable conservative target for most freelancers earning above a middle-income threshold.
The Gross vs. Profit Question
There’s a legitimate debate about whether to set aside a percentage of gross receipts or of estimated profit.
Setting aside a percentage of gross (every payment received) is simpler and more mechanical. You don’t have to estimate expenses or calculate profit in real time. The trade-off is that you’ll overshoot — you’ll reserve money you don’t actually owe, because your expenses reduced your taxable income below your gross. That overshoot becomes a surplus when you file, which acts as an emergency reserve for the following year.
Setting aside a percentage of estimated profit is more accurate but requires you to track expenses continuously and have a good estimate of your effective rate. It’s the right approach if you have reliable expense tracking and a solid sense of your annual profit margin.
For most freelancers, especially those with variable income, gross-receipts provisioning is more reliable. Overshooting slightly beats the alternative. If you have £5,000 in surplus after filing, you’re not worse off — you have a meaningful buffer heading into the next year.
The Timing Problem
Setting aside the right percentage matters less than the timing. A freelancer who sets aside 35% correctly but does it at the end of the month has already spent some of what they needed to move. A freelancer who moves the percentage on the day each payment arrives never has to make that decision.
The mechanical discipline is: payment arrives, transfer happens. The amount sitting in your current account is yours to use. The amount in the tax reserve account is not. Treat the reserve as a liability, not savings, because it is one.
This integrates directly with how you handle quarterly estimated payments — if the reserve is properly funded, quarterly payments come out of it without drama. If the reserve is under-funded, quarterly payments force decisions about which other obligations to delay.
Adjusting the Percentage Over Time
Your set-aside rate isn’t fixed. It should shift as your income changes and as you learn what you actually owe versus what you provisioned.
At the end of each tax year, compare what you set aside to what you actually owed. If you had significant surplus, reduce your set-aside rate slightly. If you came up short, increase it. Two or three years of this calibration produces a rate that’s accurate for your specific income level, expense structure, and jurisdiction.
The feast-or-famine cycle makes this harder — your income level may not be consistent enough to calibrate precisely. In that case, err on the side of over-provisioning in strong months and accept that you’ll rebuild the reserve in slow ones.
How Much to Save for Freelance Taxes: The Starting Number
If you don’t want to run the full calculation right now, here’s a starting point: 30% for income below the equivalent of $60,000, 35% for income above it, in a high-income country. For Germany and the Netherlands, add 5% to those figures.
That’s an overshoot for some situations and an undershoot for very high earners in high-tax jurisdictions. But it’s a better starting point than 25%, and it gives you room to adjust once you’ve filed your first return and know what you actually owe.
The worst outcome isn’t setting aside slightly too much. It’s the conversation with yourself in April when the bill is three times larger than you expected and the money was spent six months ago. Getting the tax reserve right is one piece of managing money as a freelancer — the rest of the financial structure matters just as much.
