VAT Reserve for Freelancers: Why That Money Isn't Yours

The invoice is paid, the money is in your account, and the balance looks good. A few weeks later the VAT prepayment comes due, and suddenly things are tight. Many freelancers know this pattern. The reason is rarely carelessness. It's a mental slip that creeps in easily: treating VAT as income. It isn't.

This article is about why VAT was never your money in the first place, how much you should set aside, and how to organize it so that payment day never catches you off guard again.

Why VAT isn't your money

You're just the pass-through

When you write an invoice with VAT, you're collecting it on behalf of the state. Your client pays you the gross amount, you keep the net amount, and you pass the VAT on. You're the pass-through, not the recipient. If you don't show VAT on your invoices, this topic only applies to you once that changes.

That sounds trivial, but it has a clear consequence: the part of your account balance that consists of VAT was never available. It only looks that way because it sits in the same account as your own money.

The account balance doesn't tell the whole story

A balance of €12,000 feels different from a balance of €9,000. But if €3,000 of that is VAT you have to remit in the coming weeks, you effectively have €9,000. If you don't keep this cleanly separated, you're planning with money that doesn't exist, and later you wonder where the shortfall came from.

How much you should set aside

The simple rule: the full VAT amount

The safest rule is also the simplest: from every incoming payment, set aside exactly the VAT amount shown on the invoice. Not more, not less, and above all not at some point later, but immediately.

The advantage of this rule: you don't have to estimate anything. The amount is right there on your invoice. If your client transfers €7,140 and €1,140 of that is VAT, €1,140 goes into the reserve. Done.

Input tax: why the reserve should still stay full

You also pay VAT on your own business expenses, which you can usually offset as input tax. In the end, you only remit the difference, the so-called VAT payable. Even so, it's smart to set aside the full VAT amount and not just the estimated difference.

Here's why: input tax fluctuates with your expenses, and your expenses have already been paid from your business account. If you set aside the full amount, you automatically build a small buffer that's left over on payment day, instead of possibly having to top up. After the return is filed, you move that buffer cleanly back to your business account.

When the reserve becomes due

How often you remit VAT, and whether it becomes due before your client has even paid, depends on your individual situation. This is exactly where a second trap lies: depending on your accounting method, the tax can be due while the client's money is still outstanding. THA·ONE is a planning aid, not tax advice within the meaning of the German Tax Advisory Act (StBerG). Which rules apply to you, what deadlines you have and how high the payments actually turn out is something to clarify with your tax advisor. For planning purposes, it's enough to know this: the amount has to be in the account on the due date, and the due date doesn't depend on your client.

How to set VAT aside properly

Step 1: A separate account for VAT

The most important step is a separate account that exists only for taxes. A sub-account or a second business account is enough. What matters is that the money no longer sits in the account you pay your running expenses from. What you don't see, you don't spend.

Many freelancers keep the VAT reserve and the income tax reserve in the same tax account. The 3-account method for tax reserves describes how that works in detail. The only important thing is to track both amounts separately so you know which part is for what.

Step 2: Transfer immediately with every incoming payment

As soon as a client payment arrives, you transfer the VAT portion. Not at the end of the month, not "when I get around to it", but as a fixed part of your invoicing workflow: check the payment, transfer the VAT, mark the invoice as paid.

If you write lots of small invoices, you can also batch this once a week. By the way, a standing order doesn't work well here, because incoming payments fluctuate. The VAT portion is a percentage, not a fixed sum.

Step 3: Enter payment dates in your liquidity plan

The reserve is only half the battle. The other half is knowing when the money goes out. Enter the VAT payments as fixed expenses in your liquidity plan, just like rent or insurance. That way you can see months in advance whether the reserve will be enough on the due date.

A liquidity tool with a reserve planner, like the one THA·ONE offers, shows you the difference between what you've set aside (ACTUAL), what you'd need (TARGET), and the gap in between (GAP). If you just want a rough overview first, the free liquidity quick check is enough.

Step 4: Reconcile monthly

Once a month, you reconcile: how much VAT have you invoiced, how much of it has been paid, how much is sitting in the tax account? If the numbers match, you're done. If not, you know immediately where to fix things, and not just on payment day.

Worked example: three months of VAT reserve

The following example is fictional and for illustration only. The VAT rate of 19% is an assumption, as are the input tax amounts.

Lena is a consultant and writes her invoices with VAT. With every incoming payment, she puts the full VAT amount into a separate account.

After three months, €3,420 sits in the tax account. In this example, the actual VAT payable is €3,420 minus €550 input tax, i.e. €2,870. Lena transfers the €2,870 to the tax office and moves the remaining €550 back to her business account.

What the example shows: at no point did Lena have to recalculate, estimate or hope. In February, a weaker month, she had no reason to worry, because the reserve from January was untouched. And in March, the strongest month, she didn't plan with €9,520 but with €8,000.

Typical mistakes and how to avoid them

"Borrowing" from the reserve for a moment

A common mistake is dipping into the tax account because a purchase is coming up or a client is paying late. The problem: the VAT is still due, and then two amounts are missing at once. If you have to touch the reserve, that's not a reserve problem, it's a liquidity problem. The article Liquidity planning in 5 steps helps you find the actual cause.

Setting aside only the estimated VAT payable

If you only set aside the difference between VAT and input tax, you have to re-estimate every month and end up short in months with few expenses. The full VAT amount is simpler and safer.

Mixing VAT and income tax

The two taxes have different rhythms and different logic. VAT is a fixed percentage of revenue; income tax depends on your profit. If both sit unseparated in one pot, you never know whether the pot is enough.

Conclusion

VAT was never your money. It only sits in your account for a short while before it moves on. Once you've internalized that, you've already taken the biggest step. The rest is routine: a separate account, the full VAT amount with every incoming payment, the payment dates in your liquidity plan, and a monthly reconciliation.

The result isn't a higher profit, but an honest account balance. And an honest account balance is the basis for every decision you make as a freelancer: whether you can invest, whether you can afford to turn down a job, whether you can afford a month off.
