Tax Office Cracks Down on Amended Tax Return Deductions

Norwegian tax authorities are increasing scrutiny of income tax returns where deductions have been amended, seeking to verify the accuracy of reported information. The move comes as a growing number of taxpayers are making changes to their deductions before filing, prompting a response from the Skatteetaten, the Norwegian tax administration.

More than 550,000 individuals increased their deductions by at least 10,000 Norwegian kroner (approximately $925 USD as of February 10, 2026) before submitting their 2024 income tax returns. This represents an increase from 535,000 people the previous year and 503,000 for the 2022 income year, according to a statement released by the Skatteetaten.

“The increase in the number of changes to deductions and the investigations we have carried out are leading us to strengthen our control work in the area of deductions,” said Odd Woxholt, Divisional Director at Skatteetaten. “We want to make people aware of the correct use of deductions.”

All tax returns are automatically checked when submitted. If taxpayers amend deductions or information provided, the Skatteetaten can compare it with data held by banks, employers, or its own records. This automated cross-referencing is a standard practice in many developed tax systems, designed to minimize errors and detect potential fraud.

Woxholt indicated that the Skatteetaten will be examining past returns as well as focusing specifically on deductions in the upcoming tax return filing for the 2025 income year. “Based on the knowledge we now have, we will both investigate back in time and we will focus particularly on deductions in the coming tax return for the income year 2025,” he stated.

The two deduction categories that have seen the most significant increases are travel deductions and interest payments on domestic debt. The rising cost of living and fluctuations in interest rates are likely contributing factors to these increases, although the Skatteetaten’s increased scrutiny suggests a concern that some claims may be inaccurate or improperly calculated.

The increased focus on tax compliance in Norway comes at a time when tax authorities globally are facing challenges. A recent report highlighted the strain on tax administrations, including the IRS in the United States, due to staffing shortages and increased complexity in tax laws. The Daily Overview reported that the IRS has shed over 20,000 jobs and is grappling with a significant lawsuit, while simultaneously being tasked with implementing new tax legislation. This has led to concerns about slower service, longer refund processing times, and a greater reliance on private tax preparers.

While the Norwegian Skatteetaten has not reported similar levels of staffing cuts, the increased workload associated with verifying deductions suggests a need for efficient resource allocation. The agency’s move to strengthen control measures reflects a broader trend among tax authorities to enhance compliance and ensure the integrity of the tax system.

The situation also highlights the importance of accurate record-keeping for taxpayers. Individuals claiming deductions should retain supporting documentation, such as receipts and statements, to substantiate their claims in case of an audit. The Skatteetaten’s automated checks and increased scrutiny mean that errors or omissions are more likely to be detected.

the increased attention on deductions comes amidst ongoing efforts to address tax avoidance and evasion. In the United States, for example, there is a crackdown on the Employee Retention Tax Credit (ERTC), with a ban on payments for certain quarters of 2021 if claims were filed after January 31, 2024, as reported by Tax1099.com. While the Norwegian context differs, the underlying principle of ensuring accurate tax reporting remains consistent.

Taxpayers who have amended their returns or are unsure about their deduction claims are advised to consult the Skatteetaten’s website or seek professional tax advice. The IRS also provides guidance on amended returns, explaining when and how to file Form 1040-X, and offering options for direct deposit of refunds. According to the IRS, amended returns are necessary when there are changes to filing status, income, deductions, credits, or tax liability.

The Skatteetaten’s increased vigilance underscores the importance of transparency and accuracy in tax reporting. As tax authorities worldwide grapple with evolving challenges, maintaining the integrity of the tax system remains a critical priority.
