Building Tax Reserves: The 3-Account Method for Freelancers
The tax bill never comes as a surprise – it just gets ignored. With three accounts and one fixed rule, the topic is settled for good.
- VAT and income tax are the two biggest items sitting in your account that do not belong to you.
- The 3-account method separates business account, tax account and reserve account – the transfer becomes a routine instead of a decision.
- A fixed percentage per incoming payment is simpler and safer than a monthly estimate.
- The reserve is reconciled and adjusted once a year with the tax assessment.
Few things get freelancers into trouble as reliably as the tax bill. Not because it comes unexpectedly – everyone knows it is coming. But because the money meant for it has long since disappeared into other expenses. The solution is not discipline, but a system that makes discipline unnecessary.
Why the money in your account is not yours
When a client pays an invoice of €5,950, there are €5,950 in the account. But only €5,000 of that belongs to you. The €950 of VAT is a pass-through item: you collected it for the tax office and pass it on with the next advance return.
Later, part of the €5,000 also leaves as income tax – depending on profit and situation, often a quarter to a third. And when your profit rises, the tax office raises the prepayments for the current year and additionally demands the back payment for the previous year. That is the moment things get tight: two tax years in one.
Anyone who reads the account balance as "my money" is planning with figures that do not exist.
The 3-account method
The idea is simple: money that is not yours leaves the account you work with immediately. For that you need three accounts – free sub-accounts at your bank are often enough.
Account 1: Business account
Everything arrives here and all business expenses leave from here. Rent, software, insurance, owner's salary. The balance here is the only number you work with day to day.
Account 2: Tax account
With every incoming payment you transfer two amounts here: the VAT contained in full, and a fixed percentage of the net amount for income tax. Only payments to the tax office are made from this account.
Account 3: Reserve account
A fixed amount per month until the reserve is in place – as a rule of thumb, three months of expenses. This reserve is for slow periods, illness and downtime. Not for taxes, not for the new laptop.
The rule that carries everything
The method only works with a fixed rule that requires no decision. For example:
With every incoming payment: VAT plus 30% of the net amount to the tax account. On the 1st of every month: €400 to the reserve account.
Whether 30% is the right rate depends on your profit and personal situation – the last tax assessment and your tax advisor provide the basis. More important than the exact rate is that the transfer happens automatically. Many banks allow standing orders with percentage rules; otherwise the manual transfer takes thirty seconds right after checking the incoming payment.
Example (fictional figures)
A graphic designer receives payments of €8,330 gross per month (€7,000 net plus €1,330 VAT). Her rule: VAT in full, 30% of net for income tax.
| Movement | Amount | Account |
|---|---|---|
| Incoming payment | €8,330 | Business account |
| VAT | −€1,330 | → Tax account |
| Income tax reserve (30% of €7,000) | −€2,100 | → Tax account |
| Reserve (monthly rule) | −€400 | → Reserve account |
| Remaining for operations and owner's salary | €4,500 | Business account |
The business account shows €4,500, not €8,330. In the first month that feels like less. After twelve months there are around €41,000 in the tax account – and the VAT returns, the income tax prepayments and the back payment are simply transfers between your own accounts.
What happens with too much or too little reserve?
Once a year, when the tax assessment arrives, you reconcile. If there is more in the tax account than you need, you can move the surplus to the reserve or lower the percentage. If it was too little, you raise the rate. After two or three years the reserve is surprisingly precise – and the tax bill an event without a racing heart.

Conclusion
Tax reserves do not fail because of knowledge but because of daily life. The 3-account method takes the decision out of daily life: what is not yours leaves the business account immediately. If you want to know how high the reserves should be over time and when the big payments fall due, the best way is a twelve-month forecast with a reserve planner – see liquidity planning. And how such a plan is built is explained in liquidity planning for freelancers in 5 steps.
