The Brazilian Federal Revenue Service (RFB) issued COSIT Ruling No. 31, dated March 5, 2026, providing important clarification regarding the tax treatment applicable to unused IPI credit balances within the statutory period.
The interpretation adopted by the tax authorities recognizes that, after the lapse of the five-year statute of limitations, without the taxpayer utilizing the IPI credit through offset against the tax itself, refund, or compensation with other taxes, the credit right is extinguished, requiring the accounting write-off of the corresponding asset.
In this context, the Federal Revenue Service concluded that the expense arising from the write-off of time-barred IPI credits is deductible for purposes of calculating Corporate Income Tax (IRPJ) and the Social Contribution on Net Profits (CSLL), when the taxpayer is subject to the actual profit regime (Lucro Real).
Accounting Nature of the IPI Credit
The ruling is based on the premise that recoverable IPI does not form part of the acquisition cost of goods. Instead, it is recorded as an asset on the balance sheet, representing a credit right of the taxpayer vis-à-vis the tax authorities.
As long as the credit remains usable, it composes the company’s assets. However, if not utilized within the five-year period, the right to use the credit becomes time-barred, requiring the write-off of the asset, with corresponding impact on the company’s financial results.
This write-off results in an accounting expense corresponding to the loss of the credit right.
Deductibility in the Calculation of Taxable Profit
The Federal Revenue Service recognized that this expense may be deducted in determining the IRPJ tax base, for two main reasons:
- Origin in the taxpayer’s operational activities – the IPI credit arises directly from industrial operations and from the non-cumulative regime of the tax;
- Absence of an express legal prohibition – there is no provision in income tax legislation requiring the add-back of this expense to net income for purposes of determining taxable profit.
Accordingly, the loss of the time-barred credit is treated as a deductible operating expense, provided it is properly recognized in the accounting records.
Application of the Same Understanding to CSLL
The ruling extends the same rationale to the Social Contribution on Net Profits (CSLL).
Since CSLL legislation generally adopts the same taxable base as IRPJ (actual profit), the Federal Revenue Service concluded that the expense resulting from the write-off of time-barred IPI credits is also deductible for purposes of calculating the CSLL tax base.
Practical Impacts for Companies
This interpretation consolidates an important point for industrial companies that accumulate IPI credits in their tax records.
In practice, the Federal Revenue Service’s position indicates that:
- IPI credits not utilized within five years must be written off for accounting purposes;
- the loss of such credits generates a deductible expense for IRPJ and CSLL purposes;
- no add-back to net income is required in the calculation of taxable profit.
From a tax perspective, this position provides greater legal certainty regarding the accounting and tax treatment of time-barred credits, preventing the taxation of amounts that represent an actual economic loss to the taxpayer.
For industrial companies, the ruling highlights the need for effective management and control of tax credits, both to avoid the loss of the right to use them and to ensure the proper accounting and tax treatment in the event of expiration.
