Properties in Portugal must file the IPHH (Inquérito à Permanência de Hóspedes na Hotelaria) guest-stay survey with INE, the national statistics institute. Amenitiz prepares that return from the bookings already in your account and sends it to INE for you.

You connect your INE WebInq account once. Each month, Amenitiz builds the return, checks it and files it with INE on the fixed schedule below.

This applies to properties in Portugal only.

Before you start

You need your own INE WebInq login — the one you use at webinq.ine.pt. There is nothing extra to request from INE or from Amenitiz.

Have your establishment details as registered with INE to hand: your 13-digit INE establishment code, your NUTS region, your NIF, your CAE establishment type, your category and your legal business name.

Amenitiz files for your account when it is exactly one INE establishment, under one establishment code. If your account includes several properties or houses under that code, they are all reported together — you cannot choose which ones are included. If your account holds several INE establishments, Amenitiz does not file for it: you submit each establishment yourself in WebInq.

Step by step

Go to Reports → IPHH Report Settings.
Under INE WebInq credentials, enter your WebInq username and WebInq password.
In Establishment Information, fill in Establishment type (CAE), NUTS region, Category, NIF, INE establishment code and Legal business name (Designação social).
From 1 November 2026, in the same section, tick This Amenitiz account is exactly one INE establishment if every room in your account belongs to the establishment with that INE code. If you prefer to submit the return yourself, or your account holds several establishments, tick I submit the IPHH return myself instead. Amenitiz then does not submit your return or remind you about it.
In Situation, tick Has accessible rooms if that applies to your property. Tick Seasonal operation if you close for part of the year, then select your Closure months.
If your establishment reports apartments, assign each unit its typology from T0 to T6 under Apartment typology (Quadro 2). This only classifies each unit for INE — it does not choose which units are reported. A unit left blank is still reported, as T0.
Click Save.

A banner at the top of the page — Complete your IPHH settings before submitting — lists anything still missing, such as the establishment code, the NUTS region or the WebInq login. When the banner clears, your property is ready and the next monthly run files for you.

How the monthly submission works

On the 2nd of each month. Amenitiz files the previous month's return on the 2nd, at around 06:00 UTC. Complete your settings before then.
If something blocks the return, Amenitiz tries again. This happens when, for example, a guest has no country of residence or INE refuses your WebInq login. From the 3rd to the 10th, Amenitiz checks again every morning and files as soon as the problem is fixed.
After the 10th, the month is closed. If the problem is still there on the 10th, Amenitiz does not file that month at all — fixing it later does not get it filed.
The figures are checked first. Each return is validated automatically before it leaves Amenitiz: your settings, INE's official code lists, the file structure INE expects, and INE's own plausibility checks. A return that does not pass is not sent.
A month is never filed twice. Once INE has accepted a period, Amenitiz does not send it again.

⚠️ Warning

Record a country of residence for every guest, in the Country of residence field of the guest's details — not their nationality. Bookings from online travel agencies (OTAs) often arrive without one, so check those guests in particular.

Guests resident outside Portugal with no country of residence count as unidentified. INE only accepts unidentified guests up to 5% of your other foreign guests and rejects the return above that, so Amenitiz does not file it.

The check runs on arrivals, guests who stayed the night and overnight stays. Going over on any one of them blocks the whole return. Add the missing countries before the 10th and Amenitiz files the month at its next daily attempt. After the 10th, it is too late.

⚠️ Important

If you change your WebInq password, enter the new one in IPHH Report Settings. Until you do, the monthly submission fails.

Track each month's return

From 1 November 2026, IPHH Report Settings shows Your IPHH returns, which lists the last 12 months, each with its status:

Sent to INE — Amenitiz sent the return. The date and INE's reference are shown.
To be sent by the 10th — the month is being filed now.
Waiting for your data (see what's missing above) — something blocks the return. Fix it before the 10th.
INE refused your WebInq login (check it above) — enter your current WebInq password.
Refused by INE (contact us) — contact our support team.
Sent, but INE's answer never reached us (contact us before submitting it yourself) — contact our support team before you submit anything in WebInq.
Not sent — the month closed without being filed. Submit it yourself in WebInq.
You submit it yourself — you ticked I submit the IPHH return myself.

Sent to INE means Amenitiz sent the return, not that INE accepted it. INE's answer is in the email INE sends you and in your INE account, under Entrega via ficheiro XML in WebInq.

From 1 November 2026, Amenitiz also emails you:

once, when your settings are complete and Amenitiz starts submitting for you,
on the 1st, 5th and 8th, only while something blocks the previous month's return, with what is missing,
after each submission, with the month and INE's reference.

FAQs

Which INE login do I use?

Your own existing INE WebInq adherent login — the same one you use to sign in at webinq.ine.pt. There is no need to create a second adherent.

Do I need any extra code or registration?

No. You connect your own INE login and that is the whole setup. There is nothing additional to request from INE or from Amenitiz.

Is my WebInq login stored securely?

Yes. It is stored securely and used only to file your IPHH returns with INE.

Do my credentials expire?

No. But if you change your WebInq password, enter the new password in IPHH Report Settings, otherwise the next submission fails.

Are the figures checked before they go to INE?

Yes. Every return is validated automatically before submission, including INE's own plausibility checks, and a return that does not add up is not sent. The check is automatic — Amenitiz does not show you the figures for approval first.

Is my revenue (proveitos) also sent to INE?

Yes. Amenitiz fills in the revenue part of the return, Quadro 1, from your bookings and sends it to INE with the rest of the return. You do not enter these figures yourself.

Three amounts are reported for the month, all excluding VAT: total revenue, accommodation revenue and food and beverage revenue.

Total revenue covers nights, extras and custom charges. City tax, gift cards and insurance are never included.

Accommodation revenue is the nights sold. Food and beverage revenue is the extras in a category tagged as restaurant. Breakfast extras count towards total revenue, but not towards food and beverage revenue.

Discounts and refunds are taken off the line they belong to.

How do I know my return was submitted?

Check Your IPHH returns in IPHH Report Settings: a submitted month shows Sent to INE, with the date and INE's reference. Amenitiz also emails you after each submission.

INE's own answer, accepted or rejected, is in the email INE sends you and in your INE account, under Entrega via ficheiro XML in WebInq.

Can I download the return and upload it to INE myself?

You can download the IPHH report from Reports for your records, but you do not need to submit it. Amenitiz sends the return straight to INE.

From 1 November 2026, if you prefer to submit the return yourself, tick I submit the IPHH return myself in IPHH Report Settings.

What if I have several properties?

From 1 November 2026, if all your properties belong to one INE establishment, tick This Amenitiz account is exactly one INE establishment. Every property or house in the account is then reported together, under one establishment code, and there is no setting to choose which ones are included.

The Apartment typology (Quadro 2) dropdowns do not do this either: they only classify each unit as T0 to T6, and a unit left blank is still reported, as T0.

If your account holds several INE establishments, Amenitiz does not file for it. From 1 November 2026, leave This Amenitiz account is exactly one INE establishment unticked, tick I submit the IPHH return myself, and submit each establishment yourself in WebInq.
