Deductible Business Expenses in Romania: A Practical Guide

12 May 2026 · Guides

There is a phrase we hear from company managers almost daily: “I’ll put it through the company and lower my tax.” It is one of the most common misconceptions in day-to-day accounting — and the source of many unpleasant surprises during a tax audit. The reality is more nuanced: not every invoice paid by the company reduces the taxable base, and not every expense “put through the firm” is accepted by the tax authority.

The difference between a deductible and a non-deductible expense does not depend on the manager’s wishes, but on clear tax rules. A wrongly deducted expense does not simply disappear — at an inspection it is added back, with additional tax, late-payment interest and penalties. For foreign-owned companies reporting to a parent abroad, correct classification is also essential for clean group reporting and for avoiding double-taxation pitfalls.

This guide explains the mechanics of deductibility, the three main categories (fully deductible, partially deductible, non-deductible) and the frequent mistakes we see in practice. Figures that change from year to year (rates, caps, percentages) are treated as reference points — always verify the value in force for the current tax year.

The golden rule: business purpose and supporting document

The Romanian Fiscal Code uses a principle that is simple to state but essential: an expense is deductible if it is incurred for the purpose of the economic activity. In other words, the expense must have a real, demonstrable link to the company’s income or scope of activity.

The second pillar is the supporting document. No expense is deductible without a document backing it — invoice, fiscal receipt showing the company’s details, contract, payroll, expense report. A payment that is real but undocumented is treated, for tax purposes, as if it never happened. In the era of e-invoicing (e-Factura) and SAF-T, this documentary traceability matters even more, because authorities can automatically cross-check reported data.

Combining the two rules gives a practical test you can apply to any expense:

• Is it linked to the business? If the honest answer is “no”, the expense is most likely non-deductible.
• Is there a correct document in the company’s name? Without it, deductibility falls away regardless of the economic justification.
• Is it fully deductible, or is there a legal limit? Many expenses are accepted only in part.

Fully deductible expenses

This category covers expenses that directly support the activity and, under normal conditions, are accepted at 100% when calculating the tax result, provided they are properly documented:

• Raw materials, supplies and goods purchased for production or resale;
• Salaries and related contributions, plus staff costs set by law or contract;
• Rent and utilities for premises used in the activity (registered office, warehouse, work point);
• Necessary services: accounting, consultancy, IT, maintenance, transport, advertising;
• Depreciation of fixed assets used in the activity, per legal useful lives;
• Interest and financing costs, within the legal deductibility limits.

Be careful, though: even here, “fully deductible” does not mean “automatically accepted.” For services, for example, the tax authority may require proof of actual delivery (reports, deliverables, correspondence), not just the invoice. Many audit adjustments arise from services invoiced between related companies without supporting documentation — a particularly sensitive area for group structures.

Partially deductible expenses — where most mistakes happen

This is the trickiest zone. The expenses are real and business-related, but the law allows only partial deduction or a deduction up to a cap. This is where most of the errors we correct are concentrated.

Protocol is the classic example: deductibility is capped at a percentage of a calculation base, and anything above the cap becomes non-deductible. Cars pose another common trap: if the vehicle is not used exclusively for business and you keep no trip log, part of the fuel, maintenance and VAT cannot be deducted. Social expenses (aid, gifts for employees’ children, events) are deductible only up to a percentage of the payroll fund; above that threshold they become non-deductible.

Because these caps and percentages change periodically, treat any figures in an article as indicative and confirm the amount applicable to the current tax year. A significant part of our services consists precisely in applying these limits correctly, month after month.

Non-deductible expenses

Some expenses are excluded from deduction by law, regardless of justification. The most common:

• Personal expenses of the manager or shareholders, unrelated to the activity;
• Fines, penalties and interest owed to authorities (state budget, traffic fines, etc.);
• Expenses without supporting documents or with documents that fail legal conditions;
• Corporate income tax itself and certain expressly excluded levies;
• Missing inventory that is neither attributable nor insured;
• Sponsorship — special regime: not a deductible expense, but it may qualify for a tax credit within limits.

A special case is “borderline” expenses: phones, laptops or subscriptions used both personally and professionally. Mixed use must be treated cautiously — it may be partly non-deductible if the link to the activity cannot be justified.

What happens at a tax audit

At an inspection, the audit team recalculates the tax result. Each wrongly deducted expense is removed, the taxable base rises, and the tax is recomputed. On top of the tax difference, late-payment interest and penalties are added for the whole elapsed period. So an apparent short-term saving can turn, after a few years, into a considerably larger amount to pay — a point not to underestimate when reporting to a parent company.
