Form 184

Form 184: sharing the income out among the members

A comunidad de bienes or a sociedad civil with no commercial purpose does not pay tax on its profit: it shares it out. The 184 is where it tells Hacienda how much belongs to each of them, so that it shows up on their draft annual return.

What form 184 is

Form 184 is the informative return for entities under the income allocation system: comunidades de bienes, sociedades civiles with no commercial purpose, herencias yacentes and comunidades de propietarios carrying out an economic activity.

These entities have one peculiarity: they obtain income but are not taxed on it. The profit is allocated to their members according to their share, and each of them declares it on their own IRPF return. The 184 is the piece that connects the two: without it, Hacienda does not know how much belongs to whom.

Nothing is paid over. But it is the form every member's return depends on, so a mistake here is multiplied by the number of members.

Who has to file it

Entities under the income allocation system that carry out an economic activity or whose income goes over €3,000 a year. Below that and with no activity, there is no obligation:

  • Comunidades de bienes. By far the most frequent case.
  • Sociedades civiles with no commercial purpose: professional practices, farming, livestock, forestry or mining activities. Those that do have a commercial purpose file form 200, not this one.
  • Herencias yacentes — estates not yet distributed among the heirs — and inherited co-ownerships running an activity.
  • Comunidades de propietarios — the owners' associations of a block of flats — that carry out an economic activity: letting the façade for advertising or the roof for aerials is the typical case.

184 or 200, never both

It is the most expensive classification error in this figure. A sociedad civil with a commercial purpose has been a Corporation Tax payer since 2016 and files form 200. One with no commercial purpose allocates income and files the 184. Choosing wrongly means having filed the wrong form for years.

Deadlines

When the 184 is filed

With the weekend shifts already applied: when the last day falls on a Saturday, a Sunday or a public holiday, the deadline ends on the next working day.

PeriodDeadlineNote
Full tax year1 January → 2 FebruaryIn 2026, because 31 January falls on a Saturday

It goes in the same block as the 190, the 180 and the 182: January's four informative summaries. And it pays to file it early, because the members need it for their annual income tax returns.

What information it carries

For each member of the entity:

  • NIF, first name and surname or company name.
  • Their share at 31 December.
  • The allocated income, broken down by type: income from an economic activity, investment income, capital gains and so on.
  • The withholdings borne by the entity that are allocated to them.
  • The bases of any deductions they are entitled to.

And about the entity itself: the result for the year, the method used to determine the income — estimación directa normal, simplificada or estimación objetiva — and the activity.

Two things to be clear about

The profit is allocated whether it has been shared out or not. If the entity earns €40,000 and decides to leave it inside to invest, the members are taxed on that €40,000 all the same. The allocation is automatic and does not depend on the money leaving.

The percentage is the one on record, not the one agreed verbally. Unless the constitutive agreement says otherwise, the shares are presumed to be equal. Changing that has tax consequences and you have to be able to prove it.

Watch out for this

The mistakes that come up most on the 184

The 184 goes wrong on the share-out, not on the sum. And a mistake here reaches the annual return of every member.

Filing the 184 when you should be filing the 200

It happens when a sociedad civil has a commercial purpose and nobody classified it. Since 2016 that one is taxed under Corporation Tax, and years of filing the wrong form do not sort themselves out.

Percentages that do not match the agreement

If the share-out declared does not match the shares on record, the adjustment reaches every member's return. And that is several returns, not one.

Forgetting the withholdings borne

The withholdings applied to the entity are allocated to the members too. If they are not declared, each of them overpays on their own return without knowing it.

Filing it late

The deadline is January, and the members need it for their own returns. Filing it in April means nobody's draft return came out right.

Where every number on the 184 comes from

Nothing has to be typed in again: the form is worked out from the invoices and the expenses you have already entered during the period.

  • The members and their percentages live on the company record, not on a separate sheet.
  • The result for the year comes from the year's invoices and expenses.
  • The share-out is worked out with those percentages, down to the cent.
  • The withholdings borne are allocated to each of them in proportion.
  • And each member can see what income is allocated to them before filing their own return.

And you can open any box

Every amount on the form can be expanded to see exactly which invoices and which expenses make it up. That is what turns a figure into something you can defend if you are asked.

Questions about form 184

The entity: the comunidad de bienes, the sociedad civil with no commercial purpose, the herencia yacente. It is not filed by each member, even though it is each member the contents affect.
No. It is informative: the one who pays is each member, on their own annual income tax return, for the share allocated to them.
It is allocated all the same. The allocation does not depend on the money leaving the entity: it depends on the money having been generated.
If it carries out an economic activity, yes. The typical case is letting the façade for advertising or the roof for mobile phone aerials: that generates income, and it is allocated to the owners.
The 184 if the entity allocates income and the 200 if it is a Corporation Tax payer. The line is drawn by the commercial purpose, and we explain it on the sociedades civiles page.

This page is for information and is reviewed whenever the legislation or the calendar changes. It does not replace your accountant: for your own case, ask someone who knows your numbers.

So the 184 stops taking an afternoon

If the invoices and the expenses are in, the form is already done.
