Loss carryover provisions are a crucial aspect of tax law, allowing businesses to deduct current year losses against future profits (carryforwards) or past profits (carrybacks). These provisions help businesses ‘smooth’ their risk and income, making the tax code more neutral across investments and over time. However, the rules governing loss carryovers vary significantly across countries, impacting businesses’ tax planning strategies.
For instance, twenty out of the 35 European countries analyzed allow businesses to carry forward their Net Operating Losses (NOLs) for an unlimited number of years. This ensures that a business is taxed on its average profitability over time. Countries like Luxembourg offer a generous limit of 17 years, while others like Bulgaria, Croatia, Cyprus, the Czech Republic, Greece, Hungary, Moldova, Poland, Romania, Slovakia, and Turkey limit their carryforwards to five years. For comparison, the United States allows businesses to carry forward their NOLs for an unlimited number of years, but limits the deductible amount to 80 percent of taxable income.
While all major European countries allow their businesses to carry forward losses, they tend to be much more restrictive with carryback provisions. Of the nine countries that allow carrybacks, only Estonia, Georgia, and Latvia provide them without a time limit. The United States, on the other hand, does not currently allow businesses to carry back losses.
Interestingly, Estonia, Georgia, and Latvia do not explicitly allow for indefinite loss carryovers. Their corporate tax systems utilize a so-called ‘cash-flow tax,’ which is only levied when a business distributes its profits to its shareholders. This makes calculating the annual taxable profits, including potential loss deductions, redundant. A cash-flow tax effectively allows for indefinite loss carryovers and avoids potentially adverse incentives associated with more generous loss carrybacks.
Several countries also impose deductibility limits. For example, Italy’s loss deduction can only be applied to 80 percent of taxable income. In 2024, Belgium returned to a more generous deductibility limit of 70 percent for loss carryforwards, from 40 percent in 2023. In contrast, Romania restricted the period that businesses can carry forward losses from 7 to 5 years and introduced a 70 percent deductibility limit.
Understanding these variations in loss carryover provisions is crucial for businesses operating in different jurisdictions. It not only impacts their tax planning strategies but also their investment decisions and risk management practices. As a responsible financial citizen, it’s essential to stay informed about these tax laws and their implications.
