INE WebInq — the definitive monthly reporting guide for AL hosts (2026)
How to submit your INE WebInq monthly tourism return as an Alojamento Local — what the form asks, how it differs from SIBA, the fields that trip hosts up, deadlines, exemptions and fixes for the most common rejection errors.
Every AL host in Portugal is required to submit a monthly statistical return to the Instituto Nacional de Estatística (INE) through its WebInq portal. It's not the same as SIBA. It's not the tourist tax. It's a third, separate obligation — and the one hosts most often forget until INE sends a notificação threatening a fine.
This pillar covers everything: what WebInq actually is, how it differs from SIBA and IPHH, what each field means, the deadlines, the exemptions, and the checklist that keeps your submissions clean month after month.
What is INE WebInq?
WebInq is the online portal INE uses to collect its official statistics from businesses. For Alojamento Local, the relevant survey is the IPHH — Inquérito à Permanência de Hóspedes na Hotelaria e Alojamento, sometimes just called the "inquérito mensal do turismo".
It's a legal obligation under the Lei do Sistema Estatístico Nacional. Non-response is an infração estatística punishable by fines starting at €500 for individuals and €1,500+ for companies. INE does escalate: first a reminder, then a formal notificação, then the fine.
You submit it monthly, per establishment, even in months when you had zero guests (a "declaração de inexistência" still counts as a submission).
WebInq vs SIBA vs the tourist tax
The three obligations get mixed up constantly. Here is the clean version:
SIBA is about who stayed. WebInq is about how many and for how long. The tourist tax is about paying the town hall. They share data but the portals do not talk to each other — you submit each one separately.
Who has to submit
Every AL registered in the RNAL (Registo Nacional de Alojamento Local) is in the WebInq universe, whether or not you had a single booking that month. INE's frame is refreshed from Turismo de Portugal quarterly, so once you have your AL número you will start receiving login credentials by post — usually 2 to 8 weeks after registration.
If you have not received credentials but you know you're registered, request them via webinq.ine.pt → "Recuperar credenciais" using your NIF and AL number. Do not wait for the letter — INE still counts the months you didn't reply.
The deadline
By the 15th of the month following the reference month. So March activity is due by 15 April, April activity by 15 May, and so on.
INE does accept late submissions without a fine if you submit within a reasonable grace window (usually the current reporting month) and it's a first offence. Repeat lateness is what triggers enforcement.
What the form asks for
The IPHH questionnaire is short (10–15 fields) but every field has a specific definition that INE audits against. Getting the definitions wrong is what causes rejections.
1. Capacity
- Number of rooms / units available in the reference month
- Number of beds (including extra/convertible beds you actually offered)
- Days open in the month
If you closed for a week for renovations, that reduces days open — it does not reduce your capacity. Both fields are independent.
2. Guests (hóspedes)
A guest in IPHH terms is a person who checked in during the reference month, counted once regardless of how many nights they stayed. A family of four checking in on 12 March counts as 4 guests in March, not 4 per night.
Split by country of residence (not nationality — this is the field hosts get wrong most often). A Brazilian citizen resident in Germany counts as Germany.
3. Overnight stays (dormidas)
Guests × nights. The family of four staying 5 nights = 20 dormidas. This is the field the tourist tax and INE numbers must reconcile against, so keep it clean.
Nights that span a month boundary are split: a stay from 28 February to 3 March contributes 1 dormida to February and 2 to March.
4. Revenue (proveitos de aposento)
The accommodation-only portion of your revenue, net of VAT, in euros. Exclude:
- Cleaning fees (report separately if asked, but not under aposento)
- Tourist tax collected
- OTA commission (report the gross amount the guest paid you, not what Airbnb transferred after commission — INE wants the accommodation value, not your net payout)
- Extras (breakfast, transfers, laundry)
VAT for AL is normally 6% on mainland and Madeira, 4% in the Azores. Divide your gross by 1.06 (or 1.04) to get the proveitos de aposento figure.
