Advanced corporate tax obligations: related-party transactions (232) and income attribution (184)
Last updated 16 July 2026 · Reviewed by Jaime Piñeira Pardo, lawyer registered with the ICAM bar, no. 138826 · English version of our Spanish guide.
3 tax obligations that many companies overlook: Form 232 declares transactions with partners or group companies over €250,000 (filed in November), Form 184 reports the income of joint ownerships and civil partnerships (January), and the article 43.1.f certificate avoids liability for subcontractor debts. Managora prepares and files them for you.
We handle the whole procedure for you, from start to finish.

What is new, and the law that applies
- Form 232 regulated by Orden HFP/816/2017, de 28 de agosto (BOE 30/08/2017): in force and applicable in 2026, with the thresholds of €250,000, €100,000 and 50% of the turnover unchanged.
- Form 184 approved by Orden HAP/2250/2015, de 23 de octubre: in force in 2026, with a filing deadline from 1 to 31 January.
- Contractor certificate: article 43.1.f of Ley 58/2003, General Tributaria: the favourable effect of silence (certificate understood to be issued if the AEAT does not resolve in 3 days) is regulated in article 126 of the Reglamento General de Recaudación (General Collection Regulation) (Real Decreto 939/2005), and the requirements to be up to date in the Reglamento General de gestión e inspección (General Regulation on management and inspection) (Real Decreto 1065/2007).
- Transactions with tax havens: the list of non-cooperative jurisdictions is set by Orden HFP/115/2023, de 9 de febrero, modified by Orden HAC/649/2026, de 21 de junio (BOE of 27/06/2026), which removes several territories from the list and adds the Russian Federation due to its international holding companies regime. It is advisable to verify the current list before filing.
- Multinational groups with a turnover equal to or greater than €750 million: added obligation of country-by-country reporting (Form 231), distinct from Form 232.
What are these 3 obligations and who do they affect?
These are 3 lesser-known tax duties affecting companies and entities, and failing to comply with them generates penalties or liability for third-party debts. They have nothing to do with each other except that they usually go unnoticed until Hacienda (the Spanish tax authority) asks.
Form 232 is an informative return of the transactions your company carries out with related parties (partners, directors, their relatives or companies in the same group) and with tax havens. Form 184 is filed by entities under the income attribution regime (joint ownerships, civil partnerships without commercial purpose and dormant inheritances), which do not pay taxes themselves but distribute their income among their members. The certificate under article 43.1.f of the Ley General Tributaria (General Tax Act) is the document that prevents you from being held liable for the tax debts of your contractors and subcontractors.
Managora identifies which ones apply to you, calculates the thresholds, prepares the transfer pricing documentation and files each form on time. You can see the price of each service on the page for Form 232, Form 184 and the contractor certificate.
Who is obliged to file Form 232 and what are the thresholds?
Taxpayers of Corporate Income Tax and Non-Resident Income Tax with a permanent establishment who carry out transactions with related persons or entities (article 18.2 of Ley 27/2014) above certain thresholds are obliged to file.
You must declare when the total transactions with the same related person or entity exceed €250,000 at market value in the financial year. Also, regardless of that amount, when the so-called specific transactions of the same type exceed €100,000, or when transactions of the same type and valuation method represent more than 50% of the entity's turnover. Specific transactions include, among others, those carried out with natural persons under the objective estimation system with a participation equal to or greater than 25%, the transfer of businesses or unlisted shares, and transactions involving real estate and intangibles.
Furthermore, it must always be filed when there are transactions or holding of securities in tax havens (regardless of the amount) or when the reduction of income from intangibles (patent box) is applied with related parties. Tax groups, economic interest groupings and temporary joint ventures (UTE) are excluded. Along with the form, the law requires keeping the transfer pricing documentation that justifies that these transactions were valued at market price. Managora prepares both.
What is Form 184 and which income attribution entities must file it?
Form 184 is an annual informative return for entities under the income attribution regime: joint ownerships, civil partnerships without commercial purpose, dormant inheritances and other entities without legal personality under article 35.4 of the Ley General Tributaria (General Tax Act). These entities do not pay tax on their profits: they report the income obtained and the part attributed to each partner, co-owner, heir or participant, who will then include it in their own Personal Income Tax, Corporate Income Tax or Non-Resident Income Tax.
Every attribution entity carrying out an economic activity must file it, regardless of the amount of its income. If it does not carry out an economic activity (for example, a joint ownership that only rents out a property), it is only obliged when it obtains income exceeding €3,000 per year.
Be careful with civil partnerships: since 2016, those with a commercial purpose pay Corporate Income Tax (Form 200) and do not file Form 184. Managora checks which of the 2 regimes your entity falls under before filing anything.
How does the article 43.1.f certificate avoid liability for your subcontractors?
When you contract or subcontract works or services corresponding to your main economic activity, article 43.1.f of the Ley General Tributaria (General Tax Act) makes you subsidiarily liable for the tax debts of the contractor or subcontractor, regarding the part of taxes that must be passed on (VAT) or withheld (Personal Income Tax withholdings) for that work or service. If the subcontractor does not pay these amounts, Hacienda can claim them from you.
The law offers an escape route: this liability will not be enforceable if the contractor or subcontractor gives you a specific certificate of being up to date with their tax obligations, issued by the AEAT (the Spanish tax agency) during the 12 months prior to the payment of each invoice. The liability is limited to the amount of the payments made without that certificate, or after 12 months have passed without renewing it.
The certificate is requested from the AEAT by the person who is going to be hired (the contractor or subcontractor), who then gives a copy to the payer. The Agency issues or denies it within 3 working days: if it does not resolve within that period, the certificate is understood to be issued in favour of the applicant (positive silence) and the payer is equally covered regarding payments for the following 12 months. Its validity is 12 months. Managora takes care of requesting it, renewing it and archiving the copy of each invoice, so that you are always covered.
What deadlines and penalties should you keep in mind?
Each obligation has its window: Form 232 is filed in the month following the 10 months after the end of the financial year, which for companies with a calendar year means from 1 to 30 November. Form 184 is filed from 1 to 31 January of the following year. The contractor certificate does not have a fixed date: it is requested when you are going to hire and is renewed before the 12 months expire.
Forms 232 and 184 are informative returns: filing them late, with incomplete or inaccurate data is penalised according to the Ley General Tributaria (General Tax Act) regime for this type of return, with fines for each piece of data or set of data and with minimum and maximum amounts. Filing voluntarily, before Hacienda requires you to do so, reduces the penalty by half.
Managora monitors the calendar for you and notifies you before each deadline. The exact amounts for each service are listed on the corresponding procedure pages.
Step by step
- 1
Review your transactions with related parties
Identify all transactions in the financial year with partners, directors, their relatives and group companies. Add them up for each related person or entity and by type of transaction, at market value and without VAT.
- 2
Prepare the transfer pricing documentation
Justify that these transactions were valued at market price. It is an independent obligation from Form 232 and Hacienda can demand it during an inspection.
- 3
Check if you exceed the Form 232 thresholds
Compare your figures with the 3 thresholds: €250,000 per related entity, €100,000 in specific transactions and 50% of the turnover. Remember that tax havens and patent box always oblige you to file.
- 4
File Form 232(From 1 to 30 November (calendar year financial years))
Mandatory electronic filing at the AEAT electronic headquarters with an electronic certificate.
- 5
File Form 184 if you are an attribution entity(From 1 to 31 January of the following year)
If you are a joint ownership, civil partnership without commercial purpose or dormant inheritance with economic activity or with income exceeding €3,000, file Form 184 with the income distribution per member.
- 6
Manage the article 43.1.f certificate(The AEAT issues it in 3 working days)
If you contract or subcontract works or services of your main activity, demand the certificate of being up to date from each subcontractor before paying each invoice. If you are the subcontractor, request it from the AEAT (Form 01C).
- 7
Renew and keep the documentation
Renew the contractor certificate every 12 months and keep a copy linked to each payment. Keep the transfer pricing documentation and the filing receipts for the forms.
A worked example
An SL (limited liability company) provides services for €180,000 and sells goods for €120,000 to another company in its same commercial group during 2025 (both pay taxes separately, without tax consolidation). In addition, it sells a premises to its sole partner for €130,000.
- Preliminary clarification: the 2 companies form a commercial group (article 42 of the Código de Comercio [Commercial Code]) but do not pay taxes under tax consolidation. If they consolidated, these transactions would be exempt from Form 232.
- Transactions with the same related entity (non-specific): €180,000 + €120,000 = €300,000.
- €300,000 exceeds the €250,000 threshold: it obliges you to file.
- Sale of the premises to the partner (specific transaction on real estate): €130,000, exceeds the €100,000 threshold: it is also declared.
The SL must file Form 232 between 1 and 30 November 2026, declaring the 3 transactions at market value and without VAT, and keep the transfer pricing documentation that justifies them.

Frequently asked questions
I only pay rent to my partner, do I have to file Form 232?
It depends on the amount. If the total transactions with that partner in the year exceed €250,000 at market value, yes. Below that threshold, and unless they are specific transactions (such as the transfer of a property for more than €100,000) or involve tax havens, you are not obliged. Managora does the calculation for you.
We are a joint ownership that only rents out a premises, do we file Form 184?
Yes, if the income exceeds €3,000 per year. The joint ownership does not pay tax: it reports on Form 184 and each co-owner declares their share of the rent in their Personal Income Tax. Below €3,000 and without economic activity, there is no obligation.
What happens if I do not ask my subcontractor for the certificate?
You can be held subsidiarily liable for the tax debts of that subcontractor (VAT and withholdings) for the part of the contracted work or service, up to the amount of the payments you have made to them without having a valid certificate. With the article 43.1.f certificate you are exonerated.
How long does the AEAT take to issue the contractor certificate?
3 working days from the application. It is valid for 12 months and must be renewed before it expires. In this certificate, silence is positive: if the AEAT does not issue it within that period, the certificate is understood to be issued in favour of the applicant and the payer is equally exonerated from liability regarding payments for the following 12 months. Even so, it is advisable to request it in advance as a practical precaution.
When is each form filed?
Form 232 in November (from 1 to 30 for calendar year financial years) and Form 184 in January (from 1 to 31). The contractor certificate is requested when you are going to hire or pay an invoice and is renewed every 12 months.
What happens to me if I file Form 232 or 184 late?
As they are informative returns, late filing or filing with inaccurate data is penalised with a fine for each piece of data or set of data, with minimum and maximum amounts. Filing voluntarily, before Hacienda requires you to do so, reduces the penalty by half. Managora files on time to avoid this.
