What Plentia calculates and what it doesn't

Plentia prepares the tax forms; it does not file them. The calculations are checked against the law, but not by a chartered tax adviser: your accountant (gestor) reviews them before filing.

What it calculates

  • The quarter's 303 and 130 from your invoices and expenses, with the breakdown of every figure.
  • The VAT you charge, kept apart from what you keep: it never counts it as income.
  • It suggests marking expenses from suppliers in another EU country that arrive without VAT as reverse charge. It never marks them on its own.
  • With a store connected, it reads the VAT charged on each order and keeps count of the €10,000 of EU sales. Store connection isn't open to customers today: you can see it in the demo.

What it doesn't calculate

  • It doesn't file anything with the tax agency, and it doesn't replace your accountant.
  • It doesn't calculate the equivalence surcharge (recargo de equivalencia), the module system (módulos), cash accounting (criterio de caja), or the Canary Islands, Ceuta, Melilla, the Basque Country or Navarre. It saves your answers and tells you so.
  • It doesn't do the annual income tax return or forms 390, 347, 111 or 115.
  • If a piece of data is missing, it doesn't make it up: the figure is marked as incomplete and says what is missing.

IVA

Every quarter you file the modelo 303 (quarterly VAT return): the VAT you charged on your sales minus the VAT you paid on deductible expenses.

RATES

21%, 10% and 4%

The standard rate is 21%. The reduced rates, 10% and 4%, apply only to what the law lists, and some transactions are at 0%.

EVERY QUARTER

The VAT you charge isn't yours

You collect it on behalf of the tax agency and pay it in with form 303. For most people the period is the calendar quarter; monthly filing is for specific cases, such as a turnover above €6,010,121.04 the year before.

BOE · VAT Regulation, art. 71
FROM ANOTHER EU COUNTRY

Services invoiced to you without VAT

If a business in another EU country provides you with a service, you declare the VAT yourself: you charge it to yourself and deduct it in the same 303. The taxable amount goes on form 349 with key “I”, and for that you need to be on the Register of Intra-Community Operators (ROI).

BOE · VAT Act, arts. 69 and 84

IRPF

Under direct assessment (estimación directa), every quarter you pay in advance with form 130 20% of your net income since the start of the year, minus what you already paid in the earlier quarters of the year.

FORM 130

20% of what you earn

Net income is what you invoice minus the expenses of the business. If your income was low the year before, the tax agency applies a small reduction.

AEAT · Amount of the advance payments
WITHHOLDING

Who withholds on their invoices

The law requires withholding for professional activities (15%, or 7% in the year you start and the two after) and for some specific activities under the module system. Selling your products under direct assessment is not on that list.

BOE · Income Tax Regulation, arts. 75 and 95

Sales to consumers in other EU countries

If you sell to consumers in other EU countries and ship from Spain, as long as you stay under €10,000 a year you charge Spanish VAT. It adds up all countries together, without VAT, for the previous year and the current one.

ONCE OVER THE LIMIT

The customer's country's VAT

As soon as the total goes over €10,000, that sale already carries the VAT of the customer's country. The limit doesn't apply if you ship from another EU country.

European Commission · One Stop Shop
ONE STOP SHOP

Form 369

To avoid registering in each country, you can declare that VAT in Spain through the One Stop Shop (OSS) and form 369. It is optional.

AEAT · Form 369
BEFORE THE LIMIT

You can also choose

You can pay VAT in the customer's country even if you don't reach €10,000. If you choose to, it binds you for at least two years.

BOE · VAT Act, art. 73

Deadlines in the year

For most self-employed people who file quarterly. If the last day for the 303 is not a working day, it moves to the next working day; the 369 deadline does not move.

If you are not on the mainland or in the Balearic Islands

Everything above is for the common tax territory. Plentia doesn't calculate these cases: it saves where your tax address is and tells you so.

CANARY ISLANDS

IGIC, not VAT

The Canary Islands don't apply VAT but IGIC, with a standard rate of 7%. Selling goods from the mainland to the Canary Islands, Ceuta or Melilla is generally treated as an export exempt from VAT.

BOE · Canary Islands Act 4/2012, art. 51
BASQUE COUNTRY AND NAVARRE

Regional (foral) tax office

They have their own tax office. If you live there, your income tax is handled by your Diputación Foral or the Hacienda Foral de Navarra. VAT follows the State's rules.

BOE · Economic Agreement, Act 12/2002

Verifactu

It is the new requirement for invoicing software: each invoice creates a record chained to the previous ones and a QR code. There are two modes; in VERI*FACTU mode, the software sends each record to the tax agency.

SELF-EMPLOYED

Before 01/07/2027

Companies, before 01/01/2027. Everyone else, self-employed people included, before 01/07/2027.

BOE · Royal Decree-law 15/2025
TWO MODES

VERI*FACTU or non-verifiable

If you choose VERI*FACTU, you must stay in it at least until the end of the calendar year.

AEAT · VERI*FACTU FAQ
WHO IS RESPONSIBLE

The maker declares it

The tax agency does not certify software: whoever makes it signs a responsible declaration.

BOE · Royal Decree 1007/2023

Plentia does not replace professional tax advice. This page summarises the general rule; your case may have exceptions. The forms Plentia prepares are reviewed by your accountant before filing.
