Companies and self-employed individuals subject to the Tax on Economic Activities (IAE) with national or provincial fees already have confirmed the payment calendar for 2026: the voluntary payment period runs from September 16 to November 20, 2026. This is established by the Resolution of June 10, 2026 from the Collection Department of the State Tax Administration Agency (BOE-A-2026-13930).
This resolution follows the usual pattern of previous years and does not introduce substantial changes in the mechanics of the tax, but confirms the specific dates you should mark on your treasury calendar to avoid surcharges for late payment.
What does this regulation establish?
The resolution sets three key operational aspects for IAE 2026 payment:
| Aspect | Detail |
|---|---|
| Voluntary payment period | From September 16 to November 20, 2026 |
| Payment channel | Credit entities collaborating with AEAT, using the payment document sent to the taxpayer |
| If the document is not received (national fees) | Request a duplicate at the AEAT Delegation of the province of the tax address |
| If the document is not received (provincial fees) | Request a duplicate at the AEAT Delegation of the province where the activity is carried out |
The payment document is the instrument that AEAT sends to the taxpayer so they can make the payment at any collaborating credit entity. Without it, or without its duplicate, it is not possible to make the payment through this channel. That is why it is essential to act in advance if it is not received.
The resolution does not modify the tax base, rates or exemptions of the IAE: it only regulates the when and how of payment for 2026.
Economic and operational impact
The IAE taxes the exercise of business, professional and artistic activities. Exempt are natural persons (self-employed) and entities with business turnover less than 1 million euros, so the actual taxpayers are mainly medium and large companies and certain professionals with significant activity.
The operational impact of this resolution is concentrated in two areas:
- Treasury planning: the IAE payment must be budgeted in the cash budget for the fourth quarter, specifically between September and November 2026.
- Document management: if the payment document does not arrive or is lost, the process of obtaining the duplicate requires going in person (or managing) before the corresponding AEAT Delegation, which consumes administrative time.
Paying outside the voluntary period (after November 20, 2026) means entering the executive period, with the surcharges that this entails according to the general tax collection regulations.
Who does it affect?
- Commercial companies (S.L., S.A. and other legal forms) with economic activity subject to IAE.
- Companies with business turnover equal to or greater than 1 million euros (exemption threshold).
- Entities that pay national fees (activity throughout the national territory).
- Entities that pay provincial fees (activity in one or several specific provinces).
- Self-employed or professionals not exempt for exceeding the billing threshold or for other specific circumstances.
- Administration, finance and advisory departments that manage tax compliance for the above companies.
Practical example
A distribution company with activity in several provinces receives at the end of August the AEAT payment document for the payment of its provincial IAE fees for 2026. The financial manager files it and plans the payment for the first week of October, within the voluntary period (September 16 – November 20). They go to their collaborating credit entity and make the payment without surcharge.
On the other hand, another company in the same sector does not receive the payment document for its national fees. Upon detecting it in October, they request the duplicate at the AEAT Delegation of the province of their tax address. With the duplicate in hand, they make the payment before November 20 and avoid the surcharge for the executive period.
The most common mistake: not detecting the absence of the document until after November 20, which forces payment with surcharge. The solution is to review in September whether the document has been received and act immediately if it has not.
What should companies do now?
- Confirm if you are subject to IAE: verify if your company exceeds the exemption threshold (business turnover of 1 million euros) and if you have national, provincial or both fees.
- Mark the dates on the treasury calendar: reserve the corresponding amount for the period from September 16 to November 20, 2026.
- Review in September the receipt of the payment document: as soon as the voluntary period begins, check that you have received the AEAT document. Do not wait until October.
- Request a duplicate if you do not receive it: if the document does not arrive or is lost, go to the AEAT Delegation of your province of tax address (national fees) or of the province where you carry out the activity (provincial fees).
- Make the payment before November 20: pay at any credit entity collaborating with AEAT using the payment document or its duplicate. Do not leave the payment for the last day.
Frequently asked questions
When is the deadline to pay IAE 2026?
The voluntary payment period for IAE 2026 for national and provincial fees runs from September 16 to November 20, 2026. Paying after that date means entering the executive period with the corresponding surcharges.
How is IAE 2026 paid and where?
Payment is made at credit entities collaborating with AEAT, using the payment document that the Tax Agency itself sends to the taxpayer. It is not necessary to go to AEAT to pay: just the document and any collaborating bank is needed.
What do I do if I do not receive the IAE payment document?
You must request a duplicate at the corresponding AEAT Delegation: if it is national fees, at the Delegation of the province of your tax address; if they are provincial fees, at the Delegation of the province where you carry out the activity. Do this with sufficient time before November 20.
Who is obligated to pay IAE in 2026?
Companies and self-employed individuals subject to IAE with national or provincial fees. In practice, exempt are natural persons and entities with business turnover less than 1 million euros, so the actual obligated parties are mainly companies and professionals with significant activity.
What happens if I pay IAE 2026 out of deadline?
If payment is made after November 20, 2026, the debt enters the executive period. This means the application of surcharges on the pending amount according to AEAT's general tax collection regulations, plus possible late payment interest.
