By San José, Costa Rica — As the December 31 deadline for Costa Rica’s ordinary 2026 fiscal year approaches, corporate leaders and financial managers are being urged to audit their internal accounting practices immediately. A convergence of improper expense recording, informal shareholder loans, and undocumented inter-company transfers is creating severe tax liabilities for businesses across the country. Local tax experts warn that failing to address these administrative errors prior to the year-end deadline could lead to inflated income tax bills, legal adjustments, and aggressive scrutiny from the Tax Administration.
Among the most pervasive issues identified by legal professionals is the commingling of personal and corporate assets. Business owners frequently utilize corporate bank accounts to settle personal financial obligations or withdraw operational cash on an ad-hoc basis without establishing formal mechanisms for dividend distribution or executive compensation. When accountants attempt to classify these withdrawals as ordinary business costs, companies risk disqualifying their claimed deductions during official tax audits.
To help readers navigate the crucial regulatory and tax obligations associated with the Costa Rica fiscal year end 2026, TicosLand.com spoke with distinguished attorney Lic. Larry Hans Arroyo Vargas from the legal firm Bufete de Costa Rica.
As the 2026 fiscal year draws to a close, corporate entities in Costa Rica must ensure strict compliance with income tax filings, transfer pricing documentation, and beneficial ownership reporting. Early financial reconciliation and proactive legal auditing are vital for businesses to mitigate tax exposure and maintain full compliance with the Ministry of Finance.

As Costa Rica’s regulatory environment grows increasingly complex, taking a proactive stance on compliance is indeed the most effective strategy for businesses seeking to avoid costly penalties and ensure long-term stability. We extend our sincere thanks to Lic. Larry Hans Arroyo Vargas for providing his valuable perspective and essential guidance as enterprises navigate the 2026 fiscal year end.
The problem arises when these cash outflows are confused with operational expenses, even though they do not meet the requirements to be deducted from income tax.

A related complication occurs when shareholder withdrawals are recorded as long-term loans to partners despite no real intent or contract governing repayment. These balances often sit on corporate balance sheets for years, artificially distorting the financial health of the enterprise while providing no tax relief. Corporate entities must carefully evaluate whether such distributions should be structured as legal dividend payments or approved director fees, depending on the legal structure of the business.
Loaning money to partners is a way to extract funds from the organization, but it is not a deductible expense.

Inter-company transactions within corporate conglomerates represent another area of heightened risk for the 2026 fiscal cycle. While operating multi-entity structures is entirely legal, moving revenue or expenses between related entities to offset high profits in one entity with losses in another without economic justification violates transfer pricing regulations. Tax authorities increasingly demand proof that management fees or shared services reflect actual market conditions and genuine economic activity.
It is always important to be clear about the economic substance.

Furthermore, tax specialists emphasize that relying solely on electronic invoices is no longer sufficient to defend deductions during a tax inspection. To establish the legitimacy of service fees or corporate billing, companies are advised to maintain robust fiscal files containing written contracts, board minutes, purchase orders, and proof of payment. Similarly, last-minute spending sprees on machinery or inventory adjustments under the assumption of obtaining immediate tax write-offs often backfire, as capital assets must be depreciated according to specific legal schedules rather than expensed outright.
To mitigate compliance risks before the December 31 closing date, corporate decision-makers are encouraged to perform an immediate tax projection alongside their legal and accounting teams. Reviewing shareholder accounts, evaluating cross-company billing, and confirming documentary support for all claimed operational expenses will allow firms to correct erroneous entries before financial statements become permanent.
There is still time to review the tax situation and correct errors before the fiscal closure. Although at this stage it is no longer possible to plan the entire year, decisions can still be made to organize accounts and close 2026 with greater clarity regarding tax obligations.

Ultimately, establishing rigorous internal controls ahead of the 2026 closure not only protects corporate liquidity in the short term but also lays a stable foundation for the 2027 tax year, shielding enterprises from potential penalties, interest, and reputational damage.
