Modelo 200 (Annual Corporate Tax Return)

What Is Modelo 200?

Modelo 200 is Spain’s annual Corporate Tax (Impuesto de Sociedades) self-assessment return. Every company resident in Spain — regardless of whether it made a profit or a loss — must file Modelo 200 each year. It is the document that formally calculates the company’s tax liability for the fiscal year and reconciles it against the instalment payments made during the year (via Modelo 202).

The form is filed electronically through the AEAT’s Sede Electrónica and requires the submission of the company’s full annual accounts as an attachment in most cases.

Filing Deadline

Modelo 200 is due within 25 calendar days after the six-month period following the end of the tax year. For companies with a standard calendar-year accounting period (1 January – 31 December), this means the filing window is 1–25 July of the following year.

Companies with non-standard tax years (e.g., ending 31 March or 30 September) have their own deadlines calculated from their specific year-end.

The Relationship Between Accounts and Tax

Modelo 200 starts from the accounting profit (resultado contable) shown in the company’s audited or verified annual accounts (Cuentas Anuales). A series of extracontable adjustments are then applied to arrive at the taxable base:

• Permanent differences: Items that are accounted for as income or expense but are permanently excluded from the tax base (e.g., non-deductible fines, tax-exempt dividends).
• Temporary differences: Items treated differently in accounting versus tax law in terms of timing (e.g., accelerated depreciation, provisions that are deductible only when realised).
• Tax loss carry-forwards: Losses from prior years can offset up to 70% of the current year’s positive taxable base (with a EUR 1 million floor).

Key Sections of Modelo 200

1. Identification and general data — company details, tax year, type of taxation regime.
2. Profit and loss account summary — imported from accounting records.
3. Extracontable adjustments — the bridge between accounting profit and taxable base.
4. Special tax regimes — if applicable (e.g., consolidation group, SICAV, SOCIMI, R&D credits).
5. Tax credits and deductions — R&D credits, double-taxation relief, investment incentives.
6. Calculation of final liability — after applying credits and subtracting Modelo 202 instalments.
7. Result: amount to pay or refund — the net settlement.

Modelo 202: Instalment Payments

Large companies and those that opt in are required to make advance instalment payments three times a year (April, October, December) using Modelo 202. These are calculated either as a fraction of the prior year’s tax liability or as a percentage of the current year’s accrued profit (the latter is mandatory for companies with turnover above EUR 10 million). These payments are credited against the final Modelo 200 liability.

Common Errors and AEAT Focus Areas

• Incorrect depreciation rates: Applying rates above AEAT table limits without justification.
• Non-deductible expenses claimed: Director remuneration without proper statutory basis, expenses lacking valid invoices.
• Transfer pricing adjustments omitted: Related-party transactions must be at arm’s length and documented.
• R&D credits claimed incorrectly: The AEAT scrutinises qualifying expenditure carefully.
