Accounting and Tax Year-End: Key Considerations for Businesses

Accounting and Tax Year-End: Key Issues to Review

The year-end closing process is not just a formal obligation. For many companies, the accounting and tax year-end is the moment when accumulated errors — sometimes from previous financial years — come to light, potentially having a direct impact on Corporate Tax.

A seemingly correct set of accounts may still conceal tax risks if certain key areas are not properly reviewed. For this reason, year-end closing should not be approached purely from an accounting perspective, but also from a tax and strategic standpoint.

1. Basic Accounting Year-End Review

Before addressing technical or tax-related matters, every company should ensure that the year-end is based on accurate and properly reconciled accounting records. At this stage, it is essential to verify that:

  • Bank accounts are fully reconciled, and all debts and receivables are correctly recorded
  • Customer and supplier balances reflect the true financial position of the business/li>
  • All transactions have been properly accounted for, including invoices, expenses, payments and receipts

It is very common to find old balances, unreviewed carry-forwards or mismatches that have accumulated during the financial year. Identifying and correcting these issues before closing the accounts helps avoid distortions in the annual result.

2. From Accounting Close to Tax Close: Preparing for Corporate Tax

Once the basic accounting review has been completed, the next step is the tax year-end closing. The objective is to prepare the financial year for an accurate Corporate Tax return.

This is when it becomes essential to analyse technical matters that are not usually reviewed on a day-to-day accounting basis but can have a significant tax impact.

Business Activity, Property Rentals and Asset-Holding Companies

This is a particularly relevant issue for many companies in Estepona and Marbella, where property investment and asset-holding structures are common. It is essential to determine whether the company is genuinely carrying out an economic activity, especially in the case of entities involved in property rental.

This classification directly affects:

  • Whether the company is considered an asset-holding entity (entity without economic activity)
  • Eligibility for certain tax incentives
  • The tax treatment of dividends, losses and share transfers

In short, it is crucial to assess whether the company has the necessary human and material resources to carry out a genuine economic activity, in order to anticipate potential tax risks.

Cancellation of Time-Barred Debts and Cleaning Up Suspense Balances

Many accounting records contain balances that no longer reflect reality: old debts, unrecoverable receivables, or outdated assets and liabilities.

At year-end, it is advisable to:

  • Write off legally time-barred debts where appropriate
  • Clean up assets and liabilities that no longer exist
  • Assess the tax impact of these adjustments

Leaving these balances unresolved can distort the balance sheet and lead to future tax issues.

Shareholder Current Accounts and Suspense Items

Shareholder current accounts and suspense balances are a classic source of tax risk. Maintaining significant or long-standing balances may result in:

  • Reclassification as hidden dividends or disguised remuneration
  • Tax adjustments for both the shareholder and the company by the Spanish Tax Authorities

Before closing the year, it is essential to analyse the origin, justification and correct treatment of these balances.

Depreciation and Impairment

Accounting depreciation and tax depreciation do not always match. From an accounting perspective, depreciation reflects the real loss in value of an asset over its useful life. However, for tax purposes, maximum depreciation rates and minimum periods are established by law, often leading to adjustments in the Corporate Tax calculation.

Key points to review include:

  • Ensuring assets are correctly classified and in use
  • Avoiding depreciation of assets already fully depreciated for tax purposes
  • Checking compliance with tax-allowed depreciation limits
  • Reviewing accelerated depreciation or special tax incentives for investment or SME status

In addition, accounting impairments must be reviewed to determine whether they are tax-deductible.

Reserves, Tax Losses and Other Deductions

Before closing the financial year, companies should carefully review:

  • The application of the capitalisation reserve and, where applicable, the equalisation reserve
  • The correct offsetting of tax losses carried forward (BINs), within legal limits
  • Available tax credits and incentives (e.g. investments, R&D+i, audiovisual production, energy efficiency) Identifying these items during the accounting close allows businesses to maximise available tax benefits.

These decisions should be made before the year is closed, not during the preparation of the Corporate Tax return.

Corporate Tax Rates, Legislative Updates and Case Law

It is essential to verify the applicable Corporate Tax rate, as not all companies are taxed at the standard 25%. For example:

  • Newly created companies may apply a reduced 15% rate in the first profitable tax period and the following one, provided legal requirements are met
  • Companies with a reduced turnover may benefit from a 23% rate, subject to specific conditions. These regimes are frequently reviewed by the Spanish Tax Authorities, so careful analysis is essential to avoid future adjustments.

The year-end process is also a good opportunity to ensure the company is not subject to any special tax regimes or restrictions, particularly in the case of asset-holding entities.
