Some debts are excluded from deferral by law, and the list is not a technicality: applying to defer one of them does not delay collection by a single day. The application is declared inadmissible, it is treated as never filed for every purpose, and the debt keeps moving towards enforced collection while the applicant believes they are protected. That is why this check comes before any other.
The list in article 65.2
Article 65.2 of the Ley General Tributaria, the General Tax Act, lists the cases in which tax debts cannot be deferred or split into instalments. In its current wording there are seven letters.
| Letter | What it excludes | Where it shows up in practice |
|---|---|---|
| a) | Debts collected by means of revenue stamps | Marginal for an individual or a small company |
| b) | Obligations of a person who must withhold tax or make payments on account for someone else | Modelos 111, 115, 123 and the other withholding returns |
| c) | In insolvency proceedings, debts that rank as claims against the insolvency estate | Only where insolvency has been declared |
| d) | Debts arising from the enforcement of decisions to recover State aid | Exceptional |
| e) | Debts arising from the enforcement of final decisions wholly or partly dismissing an appeal or claim, where the debt had previously been suspended | At the end of litigation that has been lost |
| f) | Debts arising from taxes that must by law be passed on to the customer, unless it is properly shown that the tax passed on has not actually been paid | The VAT on Modelo 303 |
| g) | Those of taxpayers obliged to make instalment payments of corporate income tax (Impuesto sobre Sociedades) | Modelos 202 and 222 |
This provision has grown over the years: letters e), f) and g) were not in the original 2003 text. The way to check which version is in force on the day you file is to open the consolidated text of Act 58/2003 in the BOE, the Spanish official gazette, and read article 65 with the validity date set to today. It takes a minute, and it is what separates an application that is admitted from one that is not.
Withholdings: the case we see most often
Letter b) sinks more applications than any other, and its logic fits in one sentence: that money was never yours. When you withhold tax from an employee's payslip or a professional's invoice, you are holding back part of another person's tax in order to pay it in on their behalf. The law will not let you fund your own cash flow with someone else's tax, so it shuts the door.
The exclusion covers Modelo 111 for employment and professional income, Modelo 115 for rent, and the other withholding and payment-on-account returns. It does not, however, cover the taxpayer's own tax, even if it is declared in the same quarter on a different form: what you withhold and what you owe yourself are two different things.
The law itself contemplates that exceptions to this rule may be laid down in regulations, in very narrowly defined cases tied to proven difficulty. They are narrow exceptions, not a general way in, and if your case might fit one it has to be studied with the rule in front of you rather than by filing the application to see what happens.
VAT, the case with nuances
Letter f) excludes debts arising from taxes that must by law be passed on to the customer (in practice, VAT) unless it is properly shown that the tax passed on has not actually been paid. That exception is real and is used, but it carries an evidential cost that should be measured before relying on it.
- The general rule is inadmissibility. Anyone who proves nothing is left out, even if their cash problem is genuine.
- Proving it means documenting invoice by invoice. Saying that customers are not paying is not enough: you have to identify which invoices from the period remain unpaid, for what amount, and show that the VAT charged on them has not reached your account.
- The part you have collected is not saved. If in the quarter you collected half of what you invoiced, what can hope to be deferred is the VAT on the other half, not the whole return.
- It has to be planned from the outset. The documents are prepared before the application is filed, because the request to produce them comes with a short deadline.
We give no success rate here and no settled administrative criterion, because whether the evidence is "proper" is judged by the collection office case by case. What can be said is that a file with the evidence assembled and one without it look nothing alike.
Corporate income tax instalments
Letter g) leaves out Modelos 202 and 222. The reason is the same as for withholdings, seen from another angle: an instalment payment is an advance on a tax that has not yet been assessed, and the law does not allow an advance to be deferred. What can be deferred, if the other requirements are met, is the tax that results from the annual corporate income tax return, Modelo 200.
For a small company this translates into a very specific calendar: the April, October and December due dates are hard deadlines with no slack, and they have to be treated as such when planning the year. The room for manoeuvre is in July, with Modelo 200, not before.
What exactly happens if you apply anyway
Here is the difference that almost nobody is clear about, and it is the one that costs the most money.
| Inadmissibility (inadmisión) | Refusal (denegación) | |
|---|---|---|
| When it happens | When the debt cannot be deferred, or when an application already decided is repeated with nothing changed | When the debt could be deferred but the deferral is not granted |
| Effect on the application | It is treated as not filed for every purpose | It existed and had effects while it was being processed |
| Effect on the enforcement period | It did not prevent it: the enforcement period starts as if nothing had ever been requested | It prevented it while the application was being processed, and the refusal opens a new payment period |
| What lies ahead | The debt already in enforcement, with its surcharge | A period under article 62.2 to pay or react |
This is the point to grasp. An application filed in the voluntary period prevents the enforcement period from starting while it is being processed, but if it ends up declared inadmissible it is deemed never to have been filed, and the enforcement period is then taken to have started on the day after the original due date. The surcharge appears, backdated, on someone who had spent weeks believing they were safe.
And if my debt is one that cannot be deferred
Not being able to defer it does not mean nothing can be done. It means the work is different.
- Separate what can be deferred from what cannot. Almost no client owes just one thing. If the same quarter has a Modelo 111 and a Modelo 130, the 111 is out and the 130 is in: separate applications are filed and whatever cannot wait is paid.
- Prioritise by cost. With cash counted, the first thing to pay is what cannot be deferred, because it is the only item certain to generate a surcharge.
- Look for pending refunds. A refund recognised in your favour can be set off against a debt, and that route exists even when the debt cannot be deferred.
- Do not repeat the same application. Asking again for the same thing without changing anything does not reopen the file or suspend collection again; all it does is lose weeks.
Before you file, read it twice
Whether a debt can be deferred is checked by looking at the form and the item, not at a general impression that "it is all owed to the tax office". A Modelo 115 for rent and a Modelo 303 for VAT from the same quarter are treated differently, and a self-employed person's Modelo 130 is nothing like their company's Modelo 202. If you have several things on your plate and do not know which is which, tell us through the deferral form: the prior inventory is precisely the part of the work that avoids inadmissibility. And if what lies behind it is years that were never filed, the right order is the one we set out in deferring what comes out of catching up on past years.
This guide describes the legal mechanism, not the outcome of your file. Whether a particular debt can or cannot be deferred depends on the item, the period and circumstances that can only be seen with the detail in front of you, and the final decision is taken by the Administration. We do not guarantee any outcome.
An inventory before filing, with one row per form
The way not to trip over article 65.2 is not to look at the total debt but to break it down. A bad quarter for a small business looks like this:
| Form | Item | Can it be deferred? | What is done |
|---|---|---|---|
| 111 | Withholdings on payroll and professionals | No, letter b) | It is paid, or financing is found elsewhere |
| 115 | Withholdings on the rent of business premises | No, letter b) | The same |
| 303 | VAT | With nuances, letter f) | We look at whether any VAT charged has not been collected, and document it |
| 130 | Instalment payment of the owner's personal income tax (IRPF) | Yes | It goes into the application |
| 202 | Instalment payment of corporate income tax | No, letter g) | It is paid |
With that table in front of you, the application is filed only for the rows that admit a deferral. Filing a single application that mixes them all is the fastest way to have it thrown out wholesale and, in passing, to lose the suspensive effect on the items that did qualify.
Frequently asked questions about your tax debt
Can I defer the VAT for a quarter in which my customers have not paid me?
Letter f) of article 65.2 allows it if you properly show that the VAT passed on has not actually been paid. Showing it means identifying the unpaid invoices and the VAT on each; asserting it is not enough, and the assessment is made by the collection office.
My application was declared inadmissible. Is that the same as being refused?
No, and the difference matters a great deal. Inadmissibility means the application is treated as not filed for every purpose, so it did not stop the enforcement period from starting. A refusal did have effects while it was being processed, and it opens a new payment period.
What if I file one application per form so that at least some get through?
That is exactly what should be done with the items that can be deferred. What does not work is splitting a single deferrable debt into several applications to stay under the threshold that is exempt from guarantees: that threshold is calculated on everything you owe.
Is there any exception for withholdings?
The law contemplates that exceptions may be laid down in regulations, in very narrowly defined cases. It is not a general way in, and you have to check the wording in force before counting on it.
