■ The "Structural Burden" of Year-end Tax Adjustments Remains Large
While year-end tax adjustment tasks strictly occur every year, the workload tends to concentrate within a short period, placing a massive burden on the HR department. Particularly in companies with a large number of employees, tasks like document collection and checking, responding to employee inquiries, and returning incomplete forms overlap, tending to overwhelm operations during the peak season.
Furthermore, the management of year-end tax adjustment tasks is becoming more complex year by year due to multi-location operations, accommodating diverse work styles, and responding to institutional revisions. While specialized knowledge is required to verify deduction certificates and reported contents, it has become difficult to secure capable personnel, making the risk of personalization and the maintenance of operational quality major challenges.
Against this backdrop, there is currently a growing demand for year-end tax adjustment mechanisms that can reduce the operational burden, extending beyond mere system implementation to include actual operations.
■ Background of Surpassing 1 Million Cumulative Users
The "Lacras Year-end Tax Adjustment BPO Service" was launched in 2018 to address these structural challenges of year-end tax adjustment tasks.
Rather than the conventional operation "premised on employees inputting data while looking at certificates," it constructed a unique processing system combining AI, OCR, and human operators based on the original concept of "processing originating from deduction certificate data." As a result, it has achieved both efficiency and improved accuracy in year-end tax adjustment tasks.
Additionally, the technology related to this service has been patented as a year-end tax adjustment business support system. (Patent No. 6289720)
Furthermore, by continuously listening to requests from adopting companies and reflecting them in improvements to standard features and optional menus, it has continued to evolve into a flexible service tailored to each company's operations.
Through the accumulation of these efforts, it has been supported by many companies as a 'service that achieves both a reduction in the burden of year-end tax adjustment tasks and an improvement in operational quality,' leading to the breakthrough of 1 million cumulative users this time.
