Provisioning your taxes: securing cash for CIT, VAT and CFE
A concrete method to provision corporate income tax, VAT and the CFE for your company: deadline calendar, set-aside rate and dedicated account, with no magic formula.

Quick answer. A company subject to corporate income tax must anticipate three flows: corporate income tax (instalments on 15 March, June, September and December, balance on 15 May), collected VAT that does not belong to it, and the CFE due on 15 December. The method: set aside each month a percentage of cash collected and forecast profit, in a dedicated account, aligned with those deadlines.
The scenario recurs in almost every young company file we handle: a profitable year, a current account that looks comfortable, then a tax deadline that turns a good year into a cash squeeze. The problem is not the amount of the tax. It is the absence of a provision. The money was spent, distributed or reinvested before the State claimed its share.
Provisioning your taxes is not saving money. It is acknowledging that part of the cash sitting in the account is already committed. This article is aimed at directors of companies subject to corporate income tax (SASU, SAS, SARL, EURL taxed at CIT). For a sole trader, whose logic rests on social contributions and personal income tax, we have covered the set-aside method for a sole trader in a separate guide.
The three taxes that weigh on a company's cash flow#
A company subject to CIT bears three levies on different calendars. Lumping them into a single mental line is the most common mistake.
Corporate income tax hits the taxable profit of the financial year. VAT, on the other hand, is not a charge: it is money collected on behalf of the State. The CFE is a local tax based on premises, due regardless of profit. Three logics, three calendars, three provisions.
| Tax | Base | Cash-flow logic |
|---|---|---|
| CIT | Taxable profit of the year | Real charge, provisioned on profit |
| VAT | Collected VAT minus deductible VAT | State's money, isolated in full |
| CFE | Rental base of the premises | Fixed charge, independent of profit |
You will find a panorama of company taxes to place these three levies within a company's full set of tax obligations.
Our reading. VAT is the most dangerous item, because it never appears as a charge in the income statement. A director looking at gross margin sees a figure that includes, in the bank account, VAT that is not theirs. It is this gap between the accounting view and the bank view that creates nasty surprises.
Step 1: estimate the annual amount of each tax#
Provisioning first requires estimating. The estimate need not be exact to the euro; it must be prudent and revisable.
Estimating CIT#
Corporate income tax is calculated on taxable profit. The reduced rate of 15 % applies up to 42,500 euros of profit, subject to conditions on turnover and capital ownership; above that, the standard rate is 25 %. Start from the forecast profit of the year, apply the relevant rate and reach an annual target.
A company generating 60,000 euros of taxable profit and meeting the reduced-rate conditions bears CIT of around 6,375 euros on the first band (42,500 x 15 %) plus 4,375 euros on the surplus (17,500 x 25 %), about 10,750 euros. That is the sum to have set aside by the time the balance falls due.
Estimating VAT#
Under the standard real regime, VAT is declared via the CA3, monthly, or quarterly if the annual VAT due is below 4,000 euros. The VAT provision is not a prudent estimate: it is a euro-for-euro calculation. All collected and not-yet-remitted VAT must remain available. The simplified VAT regime is abolished on 1 January 2027 by the 2025 Finance Act; companies still benefiting from it will move to more frequent returns, and therefore a more rhythmic tax cash flow.
Estimating CFE#
The year's CFE is most often close to the previous year's, barring a change of premises or situation. Last year's CFE notice is the best estimation base.
Step 2: set a monthly set-aside rate#
There is no universal percentage. Be wary of the "set aside 30 %" heard everywhere: that figure mixes situations that have nothing in common. The right rate depends on your margin, the applicable CIT rate and your VAT position.
Trade-off. Two approaches coexist. The first sets aside a fixed percentage of each receipt, easy to automate but imprecise if the margin varies. The second provisions VAT separately (euro for euro, from invoicing) and CIT (on estimated monthly profit), more exact but more demanding to track. For a company with steady activity, the fixed percentage suffices; for seasonal activity or volatile margins, the separate provision avoids jolts.
| Company profile | Recommended approach | Why |
|---|---|---|
| Steady activity, stable margin | Fixed percentage of cash collected | Simple, automatable, reliable enough |
| Seasonal activity | VAT provision to the euro + monthly CIT | Avoids under-provisioning in high season |
| Volatile or thin margin | CIT provision based on actual profit | A percentage of turnover would mislead |
The reliable forecast we build with our clients serves precisely to set this rate from figures specific to the company, rather than a general rule.
Step 3: open a dedicated account for tax cash#
A provision left in the operating account is not a provision: it is an intention. As long as the sum is mixed with everyday cash, it is spendable, and it ends up being spent.
We recommend isolating tax cash in a separate account. A sub-account or a dedicated reserve account is enough. The aim is psychological as much as accounting: what is separated is no longer seen as available. Banking tools such as isolating tax cash with Qonto let you create these sub-accounts in minutes, and accounting tools such as tracking VAT in Pennylane give the VAT position to provision in real time.
The underestimated risk. The risk is not only running short of cash on the deadline. It is having distributed dividends or raised the director's pay while looking at an account that held un-provisioned VAT and CIT. The sum goes out, the tax remains due, and the catch-up then falls on operating cash, at the worst time.
Step 4: align provisions with the deadline calendar#
Provisioning without a calendar means piling up cash without knowing when it will go out. Steering consists of making the provision available on the exact date of the deadline.
The CIT calendar#
CIT is paid in quarterly instalments on 15 March, 15 June, 15 September and 15 December, then a balance. A company is exempt from instalments if the previous year's CIT is below 3,000 euros: this is often the case in the first year. The balance is due on the 15th of the fourth month after year-end, that is 15 May for a 31 December close.
| CIT deadline | Date (31 Dec close) | Amount |
|---|---|---|
| 1st instalment | 15 March | Fraction of reference CIT |
| 2nd instalment | 15 June | Fraction of reference CIT |
| 3rd instalment | 15 September | Fraction of reference CIT |
| 4th instalment | 15 December | Fraction of reference CIT |
| Balance | 15 May N+1 | Actual CIT minus instalments paid |
The VAT and CFE calendar#
VAT under the standard real regime follows the monthly or quarterly CA3. The CFE is due on 15 December; a 50 % instalment is payable on 15 June if the previous year's CFE reaches or exceeds 3,000 euros. The 15 December date thus concentrates both a CIT instalment and the CFE balance: a date to watch closely. The 2026 filing deadlines complete this calendar for the other obligations.
Step 5: revise provisions at each instalment#
A provision is only correct at the moment it is set. Profit changes, margin shifts, VAT follows activity. Each instalment is a checkpoint.
In practice. At each deadline paid, compare what you had provisioned with what was actually due. If you over-provisioned, the rate can be lowered for the rest of the year. If you under-provisioned, it is better to notice it in March than to discover it in May. This quarterly review is what distinguishes a steered provision from a blind kitty.
A common case seen at the firm#
A services SASU, profitable in its first year, had provisioned no CIT because it thought it was exempt from instalments. It was indeed exempt, for the instalments. But the balance remained due on 15 May, and the account had been emptied by a year-end pay-out. The director had to forgo part of their remuneration temporarily to absorb the balance. The instalment exemption is not a tax exemption: it simply shifts the charge onto the balance.
2026 watch points. Two points deserve attention. First, the abolition of the simplified VAT regime on 1 January 2027 will require the companies concerned to file more frequently from the following year: VAT cash will have to be tracked monthly rather than overall. Second, the build-up of several deadlines on 15 December (a CIT instalment and the CFE balance) creates an outflow peak to anticipate from the autumn.
To frame these provisions against your real situation, our corporate tax support starts from your figures and your own calendar, rather than a general rule.
Frequently asked questions
What percentage of my turnover should I set aside for taxes?+
There is no universal percentage. The rate depends on your margin, the applicable CIT rate (15 % up to 42,500 euros of profit subject to conditions, 25 % above) and your VAT position. The right approach is to estimate each tax separately, then translate the total into a percentage of receipts.
Is collected VAT part of my cash?+
No. VAT collected from your customers is taken on behalf of the State and must be remitted to it. It sits in your bank account without belonging to you. Provisioning it in full, ideally in a separate account, avoids mistaking it for available margin and spending it.
When must I pay the corporate income tax balance?+
The CIT balance is due on the 15th of the fourth month after the close of the financial year, that is 15 May for a company closing on 31 December. It equals the actual CIT for the year less the instalments already paid on 15 March, June, September and December.
My company is exempt from CIT instalments: should I still provision?+
Yes. The instalment exemption applies when the previous year's CIT is below 3,000 euros, common in the first year. It does not exempt you from the tax: the balance remains due on 15 May. Without a provision, you will have to pay in one go a sum you have not set aside.
When is the CFE due?+
The CFE balance is due on 15 December. A 50 % instalment is payable on 15 June if the previous year's CFE reaches or exceeds 3,000 euros. 15 December therefore often combines a CIT instalment and the CFE balance, making it an outflow date to anticipate from the autumn.
Do I need a separate bank account to provision my taxes?+
It is not a legal requirement, but it is an effective discipline. As long as the provision stays in the operating account, it is spendable. A sub-account or a dedicated reserve account makes the sum less psychologically available and reduces the risk of consuming it inadvertently.

- The CIT balance falls on 15 May (31 December close); 15 December combines a CIT instalment and the CFE balance.
- The CIT instalment exemption (below 3,000 euros) does not exempt you from the tax: the balance remains due.
- Each instalment is a checkpoint to revise the provision and the set-aside rate.
