Basic Tax Obligations for a Company in Spain

Key points:

• Main taxes: Every company must settle the Impuesto sobre Sociedades (IS) (Corporation Tax) on its profits, the VAT on its operations, and apply withholdings to payroll or invoices from professionals.
• Deadlines and forms: Each tax is declared using an official form (e.g., Modelo 200 for Corporation Tax, Modelo 303 for VAT) and has strict quarterly or annual deadlines.
• Risks: Errors or omissions lead to penalties, surcharges and interest. In serious cases, they can result in personal liability for the directors.
• Active management: Proper tax planning not only avoids problems but also allows for the application of deductions and tax benefits that optimise the company's tax burden.

The Three Tax Pillars of Your Company

Managing a company in Spain involves a series of tax responsibilities that go beyond simply paying taxes. It is a system of periodic and formal declarations, non-compliance with which can halt business activity and lead to serious economic and legal consequences.

The three fundamental taxes that every commercial company must manage are detailed below.

1. Impuesto sobre Sociedades (IS)

This is the tax levied on the profits earned by the company throughout the year. The accounting profit is adjusted in accordance with tax regulations to determine the taxable base, to which the tax rate is applied.

The general rate is 25%. However, newly created companies can benefit from a reduced rate of 15% during their first two financial years with profits.

The annual return is filed using Modelo 200 (Form 200), but companies must make three instalment payments towards the final tax liability in April, October, and December. These advance payments ensure a progressive collection for the tax authorities.

2. Impuesto sobre el Valor Añadido (IVA)

IVA (Impuesto sobre el Valor Añadido, Value Added Tax) is an indirect tax on consumption. The company acts as a collector for the Agencia Tributaria: it charges VAT on the invoices it issues to its customers (output VAT) and, in turn, pays VAT on invoices from its suppliers (input VAT).

Quarterly (or monthly in some cases), the company must settle the difference between the output VAT and the input VAT. If it has collected more VAT than it has paid, it pays the difference to the authorities. Otherwise, it can request to carry it forward or claim a refund. The return is primarily filed using Modelo 303 (Form 303).

3. Withholding Taxes and Payments on Account

The company is required to withhold a percentage of certain payments it makes and pay it to the tax authorities on behalf of the recipient. It acts, again, as an intermediary in tax collection.

The most common withholding taxes are:

• On employee salaries (as an advance payment of their Personal Income Tax).
• On invoices from self-employed professionals.
• On rent for business premises or offices.

These amounts are settled quarterly and summarised in annual information returns. Failure to comply with this obligation can lead to significant penalties and being considered secondarily liable for the debt.

Frequently Asked Questions about Corporation Tax and VAT

1. What happens if I file the VAT return late? If you file it voluntarily before being prompted by the Agencia Tributaria, a progressive surcharge will be applied to the amount payable, but not a penalty. If the tax authorities discover the delay, they will initiate penalty proceedings.

2. My company will make a loss this year. Do I still have to file the Corporation Tax return? Yes, the obligation to file the Impuesto sobre Sociedades return using Modelo 200 exists even if the result is zero or negative (a loss). In fact, correctly declaring losses allows you to offset them against profits in future years, reducing your tax bill.

3. Can I deduct all the VAT my company incurs? You can only deduct VAT on expenses that are directly and exclusively related to your business activity and are properly justified with a full invoice. Personal or poorly documented expenses are not deductible and, if included, may be subject to an adjustment during an inspection.

Other Tax Obligations to Consider

In addition to the three main taxes, there are other formal obligations that you should not overlook.

• Impuesto sobre Actividades Económicas (IAE): (Tax on Economic Activities): Although companies with a turnover of less than one million euros and newly created companies during their first two years are exempt, all must register under the heading corresponding to their activity.

• Information returns: The company must periodically inform the tax authorities about its transactions with third parties. The best-known is Modelo 347 (Form 347), an annual declaration of transactions with customers or suppliers exceeding €3,006.05 per year.

Penalties and surcharges: Fines for errors, omissions or delays in filing returns, which can amount to a high percentage of the unpaid tax.	Preventive advice: We help you plan a tax calendar, review your returns before filing, and ensure deadlines are met.
Tax inspection: A long and stressful procedure that can disrupt the management team and review the last four financial years.	Representation and defence: We represent you during the inspection, prepare the required documentation, and defend your interests to minimise the impact of any adjustments.
Director's liability: The law allows liability for tax debts to be passed on to the director if negligent management is proven.	Advice for governing bodies: We advise directors on their duties of care to protect their personal assets from potential company debts.
Disallowance of deductions: The Tax Agency disallows the deduction of expenses or VAT amounts for not being properly justified, increasing the tax burden.	Accounting review: We analyse your accounting and invoicing processes to ensure that all deductible expenses meet the formal and substantive requirements of the law.

Final Summary

Correct tax management goes beyond filing documents. It is a strategic element that protects the assets of the company and its directors, avoids conflicts with the tax authorities, and optimises business profitability. Mistakes, often made through lack of knowledge or time, have direct and serious financial consequences.

Frequently Asked Questions about a Company's Tax Obligations in Spain

1. What is the first tax obligation when setting up a company? Before starting any activity, you must register the company in the Censo de Empresarios, Profesionales y Retenedores (Census of Businesses, Professionals and Withholding Agents) by filing a census declaration (Modelo 036), outlining your tax obligations.

2. What is a tax "modelo"? It is the official form established by the Agencia Tributaria for each type of declaration. For example, Modelo 303 is used for the quarterly VAT self-assessment and Modelo 200 for the annual Impuesto sobre Sociedades return.

3. How often do I have to file tax returns? It depends on the tax. VAT and withholding taxes are generally settled quarterly. Corporation Tax has an annual return and, where applicable, instalment payments in April, October and December; these are not regular quarterly payments. Information returns are usually annual.

4. My company has had no activity this year. Do I still have to file taxes? Yes. Even if you have had no income or expenses, you are still required to file the Impuesto sobre Sociedades return (by ticking the "inactive entity" box). Failure to comply with this formal obligation can also result in penalties.

5. Can the lawyers at the ARROWS International network in Madrid handle all of my company's tax management? Yes, the ARROWS International network in Madrid offers ongoing tax advisory services, including the preparation and filing of all returns, tax planning, and representation before the tax authorities.

6. How do I know if I am correctly applying deductions for the Impuesto sobre Sociedades? The correct application of deductions (for R&D&I, job creation, etc.) requires a detailed analysis and strict compliance with specific requirements. A prior legal report or consultation with our experts can confirm the viability of such deductions and prevent future adjustments.
