Tax Deferral in Spain: Aplazamiento and Fraccionamiento When You Cannot Pay Your AEAT Bill (2026)

A large Spanish tax bill you cannot settle on time does not have to become an enforcement crisis. Spain’s General Tributaria lets you defer a debt in a single future payment (aplazamiento) or split it into instalments (fraccionamiento) when a temporary cash shortfall prevents payment, provided you apply before the voluntary deadline closes and accept that demora interest accrues throughout.

When can you defer or instalment a Spanish tax debt?

Article 65 of the Ley 58/2003 General Tributaria gives the AEAT authority to defer or split debts in either the voluntary or the ejecutivo (enforcement) period, but the practical and financial consequences differ sharply between the two. A request filed within the voluntary payment window stops the ejecutivo period from opening and freezes the surcharge clock, though demora interest still accrues from the day after the original deadline. A request filed in the ejecutivo period does not halt enforcement: the AEAT may continue apremio proceedings, including embargo, until it resolves the application, though it must suspend the actual sale of seized assets while the file is open (Article 65.5 LGT).

Not every debt qualifies. Article 65.2 LGT excludes six categories, of which three matter to foreign property owners: debts collected via stamped paper, retainer or payment-on-account obligations owed by a withholding agent, and taxes legally charged to a third party unless you prove the amounts were never actually paid. The last exclusion means a buyer who owes the 3 per cent Modelo 211 retention on a purchase cannot defer it; the seller’s underlying CGT liability, by contrast, is eligible. Company instalment payments of corporation tax are also excluded.

For non-resident owners, the most common deferrable debts are the annual Modelo 210 on imputed or rental income, a CGT settlement after a sale, and wealth tax liabilities. The key rule is timing: apply within the voluntary period, which for Modelo 210 runs from 1 January to 31 December of the year following the income year, or the first 20 business days after a liquidation notice for an AEAT-assessed debt.

What interest applies to a deferred Spanish tax debt?

Interest is the price of deferral, and it accrues automatically from the day after the voluntary deadline until the deferred payment date. Article 26.6 of the Ley 58/2003 sets the demora rate at the legal interest rate plus a 25 per cent uplift, unless the annual budget law fixes a different rate. In 2026 the legal interest rate remains 3.25 per cent (the third consecutive prorroga of the 2023 budget under RDL 2/2026), so the demora rate is 4.0625 per cent per annum.

There is one important exception. Article 65.4 LGT and Article 26.6 LGT both provide that if you guarantee the entire debt with a bank aval solidario, a mutual guarantee society surety, or a surety insurance certificate, the applicable rate drops to the legal interest rate alone: 3.25 per cent in 2026. This is a meaningful reduction for large debts and a reason to consider a bank guarantee even when the debt is under the guarantee-exempt threshold.

Interest is calculated on the outstanding principal only. For an aplazamiento, it runs from the day after the voluntary deadline to the deferred due date (Article 53.1 RGGIT). For a fraccionamiento, interest accrues on each instalment from the day after the voluntary deadline to that instalment’s due date, and is paid alongside each instalment (Article 53.2 RGGIT).

Do you need a guarantee to defer a Spanish tax debt?

Whether a guarantee is required depends on the debt amount. Article 82.2.a of the Ley 58/2003 authorises the government to exempt low-value debts from the guarantee requirement, and Orden HFP/311/2023 (in force from 15 April 2023) raised that threshold from EUR 30,000 to EUR 50,000. For debts of EUR 50,000 or below, no guarantee is required; the AEAT processes the application on financial-difficulty documentation alone.

For debts above EUR 50,000, Article 82.1 LGT and Article 48 RGGIT require a guarantee covering the principal, the projected demora interest, and a 25 per cent buffer of both sums for voluntary-period debts. If the debt is already in the ejecutivo period, the guarantee must also cover the ejecutivo surcharge and the buffer drops to 5 per cent (Article 48.2 RGGIT). The accepted guarantee hierarchy is:

Guarantee type	Conditions	Interest rate
Bank aval solidario or surety insurance	Covers principal + interest + 25 per cent buffer (voluntary)	Legal rate only (3.25 per cent in 2026)
Mortgage or pledge	Only if you prove a bank aval is impossible; requires independent valuation	Full demora rate (4.0625 per cent)
Personal surety	Only if bank aval impossible and mortgage inadequate	Full demora rate (4.0625 per cent)
No guarantee	Debt under EUR 50,000 (Orden HFP/311/2023)	Full demora rate (4.0625 per cent)

If you cannot obtain a bank aval, Article 46.4 RGGIT requires you to submit a responsible declaration documenting the refusals you received, plus an independent valuation of any asset you offer instead. The AEAT then decides whether the alternative guarantee is sufficient. A full guarantee dispensa under Article 82.2.b LGT is reserved for taxpayers who lack sufficient assets and whose enforcement would gravely damage economic activity; it requires three years of accounts and a viability plan.

How do you apply for aplazamiento or fraccionamiento?

The application is filed electronically through the AEAT sede via the RB01 procedure. You identify yourself with a digital certificate, DNIe, Cl@ve or eIDAS, then submit the official form along with the supporting documents. For non-residents who do not hold a Spanish electronic identity, the non-resident digital filing barrier applies here too: a fiscal representative with a Spanish certificate can submit on your behalf.

The application must include (Article 46.2 RGGIT):

1. Identification of the debt: amount, tax concept, and the voluntary-period end date.
2. The causes of the temporary financial difficulty.
3. The proposed payment schedule: for an aplazamiento, the single deferred date; for a fraccionamiento, the instalment amounts and due dates. Due dates must fall on the 5th or 20th of a month (Article 52.1 RGGIT).
4. The guarantee offered, if required.
5. A bank account mandate for direct debit instalments.

If the file is incomplete, the AEAT gives you 10 days to remedy the omission. Failure to remedy means the application is treated as not filed and archived (Article 46.6 RGGIT). If the debt arose from an autoliquidacion you never submitted, the application is inadmissible: you must file the return first (Article 47.1.a RGGIT).

What happens during the resolution period?

The AEAT has six months to resolve (Article 52.6 RGGIT). If it does not notify a decision within that window, the request is deemed denied, and you may either appeal or wait for an express resolution. During the tramitation, you must keep paying the instalments you proposed in your application (Article 51.2 RGGIT). If the AEAT considers the file complex, it may set its own provisional payment calendar, which overrides yours.

If the AEAT grants the deferral, it specifies the payment dates, the bank account for direct debit, and the interest due on each instalment. The resolution may impose conditions different from those you requested. You then have two months to formalise the guarantee (Article 48.6 RGGIT); if you fail to formalise it, the ejecutivo period opens and the apremio surcharge applies.

If the AEAT denies the deferral and you applied in the voluntary period, a new payment window opens under Article 62.2 LGT. Paying within that window means only demora interest accrues; failing to pay triggers the ejecutivo period with surcharges of 1 to 5 per cent depending on timing (Article 161.2 LGT), plus enforcement. You may appeal via reposicion (one month) or a reclamacion economico-administrativa (one month).

A worked example: deferring a EUR 30,000 Modelo 210 CGT bill

Consider a non-resident who sells a Spanish property in 2025 and owes EUR 30,000 in CGT via Modelo 210, due on 31 December 2026. A liquidity shortfall prevents payment in the voluntary period, so they file an aplazamiento on 15 December 2026, requesting a single deferred payment on 31 December 2027.

Because the debt is under EUR 50,000, no guarantee is required under Orden HFP/311/2023. The application in the voluntary period prevents the ejecutivo period from opening. Demora interest accrues at 4.0625 per cent on the EUR 30,000 principal for 365 days:

Item	Amount
Principal (Modelo 210 CGT)	EUR 30,000.00
Demora interest (365 days at 4.0625 per cent)	EUR 1,218.75
Guarantee required	None (under EUR 50,000)
Total payable on 31 December 2027	EUR 31,218.75

Had the same owner guaranteed with a bank aval, the interest rate would have dropped to 3.25 per cent, saving EUR 243.75 over the year. For a larger debt, the savings compound: a EUR 100,000 deferral over 12 months at the legal rate versus the demora rate saves EUR 812.50.

Had the owner waited until after 31 December 2026 (the ejecutivo period), the apremio surcharge would apply. An early ejecutivo payment incurs a 1 per cent surcharge; late payment adds 5 per cent plus enforcement costs (Article 161.2 LGT). The voluntary-period application is therefore the single most cost-effective decision in the process.

What debts can a non-resident property owner not defer?

Three exclusions from Article 65.2 LGT are relevant to non-resident owners. First, the 3 per cent buyer retention under Modelo 211 is a withholding obligation owed by the buyer as an intermediary; it cannot be deferred. Second, if you let property and act as a retainer for tenant tax (rare for non-resident landlords but possible in certain corporate structures), that retainer obligation is excluded. Third, VAT amounts you legally charged to a tenant or buyer cannot be deferred unless you prove the amounts were never actually paid to you.

The debts that are deferrable for a typical non-resident owner include the annual Modelo 210 on imputed income, rental income Modelo 210, CGT on a property sale, and wealth tax. If a debt is already in prescription territory, see the tax prescription rules before applying; a deferral application does not pause the four-year prescription clock for the AEAT’s right to demand payment.

Practical rules that catch non-resident owners out

The voluntary-period deadline is absolute. Filing a day late moves you into the ejecutivo period, where surcharges apply and the AEAT can continue enforcement during the tramitation. The safest approach is to file the application well before the deadline, even if your documents are not perfectly assembled; the 10-day remediation period lets you fix gaps without losing voluntary-period status.

The demora rate is not the legal interest rate. Many guides conflate the two. The demora rate is the legal rate plus 25 per cent, so for 2026 it is 4.0625 per cent, not 3.25 per cent. The legal rate alone applies only to bank-aval-guaranteed debts. When comparing the cost of deferral to a private loan, use the correct rate.

The EUR 50,000 threshold is per debt, not per taxpayer. If you owe three Modelo 210 debts of EUR 20,000 each, each is under the threshold and requires no guarantee. If you owe a single EUR 60,000 CGT bill, a guarantee is required for the full amount. The threshold applies to the specific debt whose deferral you request.

Finally, the AEAT payment methods used during a deferral are the same as for any tax payment: direct debit is the standard for instalment plans, and the resolution will specify the IBAN. Ensure your Spanish or SEPA-compatible account is active throughout the plan, because a missed instalment triggers the ejecutivo period on the remaining balance and can collapse the entire fraccionamiento under Article 54.2 RGGIT.
