■ 68.6% of Payroll Operations Rely on Specific Internal Department Personnel

Payroll operations are a monthly necessity.

It is a highly sensitive task that requires constant catching up with the latest information, such as legal revisions and changes in social insurance premium rates, to ensure accurate processing.

Many companies are likely concerned about personnel dependency, wondering "what happens if the person in charge leaves?"

Therefore, in collaboration with MHC TripleWin Co., Ltd., we conducted a survey on "awareness of external outsourcing of payroll operations" targeting 67 men and women nationwide who had previously responded in a preliminary survey that they had "experience in payroll calculation and HR/labor management operations at a company."

※ When quoting the content of this press release, please take the following actions:

■ 68.6% Rely on Specific Internal Department Personnel

First, we investigated how companies primarily perform their payroll calculations.

The most common response was "Performed by internal accounting/general affairs staff" at 37.3%. This was followed by "Performed by internal HR/labor management staff" at 19.4%, and "Performed by management" at 11.9%. It appears that in smaller companies, management often handles payroll themselves.

On the other hand, looking at external outsourcing, "Outsourced to tax accountants/social insurance labor consultants" was 6.0%, and "Outsourced to BPO companies" was 3.0%. Currently, companies that outsource payroll are still a minority.

In Question 2, we asked for reasons for their chosen payroll method, and some responses are introduced below.

"Performed by internal accounting/general affairs staff"

・Because the number of employees is less than 10, the payroll staff can handle it sufficiently. (70s, Male)

・Because that person has been doing it for many years. (50s, Male)

"Performed by internal HR/labor management staff"

・To handle all labor management. (40s, Male)

・A dedicated person was necessary due to the large number of people. (70s, Male)

"Performed by management"

・Because I am the only one who can do it. (40s, Male)

・Few employees. (60s, Female)

・Because I run the company alone. (50s, Female)

"Outsourced to tax accountants/social insurance labor consultants"

・It might not be good for employees to know other employees' salaries. (60s, Male)

・It's the president's policy. (60s, Male)

"Outsourced to BPO companies"

・To reduce employee overtime. (40s, Male)

Responses highlighting the risk of personnel dependency due to in-house operations, such as "I am the only one who can do it," "a specific person has been doing it for many years," and "to reduce employee overtime," were prominent.

A system that relies on specific individuals always carries the risk of operations stalling due to transfers or resignations.

■ 12.3% Responded "Have Considered Outsourcing"

Next, we asked those who do not outsource to BPO companies if they have ever considered outsourcing payroll calculation.

As a result, 12.3% responded "Yes," and 87.7% responded "No." Currently, about 1 in 8 companies have considered outsourcing, which is not a large number.

While still not the majority, companies facing challenges with workload and personnel dependency are beginning to consider it.

In Question 4, we asked for reasons for considering outsourcing, and some responses are introduced below.

Reasons for considering outsourcing

・To reduce workload. (30s, Male)

・Efficiency. (60s, Male)

・Linked with automatic calculation. (60s, Male)

・Already doing it. (60s, Male)

In addition to monthly routine tasks, if irregular tasks such as year-end adjustments and legal revisions overlap, a single person in charge may not be able to handle everything. Considering stable operation, outsourcing is one option to consider.

■ When Outsourcing, "Accuracy" and "Information Security" are Equally Prioritized at 37.5%

We asked those who have considered outsourcing what aspects they prioritize when doing so.

As a result, "accuracy" and "information security" were tied at 37.5%, becoming the most prioritized points. This was followed by "adaptability to legal revisions" and "track record/reliability" at 12.5% each.

In Question 6, we asked for reasons for prioritizing "accuracy" and "information security," and some responses are introduced below.

Those who responded "Accuracy"

・To prevent legal troubles. (30s, Male)

・Mistakes are troublesome. (60s, Male)

Those who responded "Information Security"

・Safety and security come from security measures. (60s, Male)

Errors in payroll calculation are not merely administrative issues. They can not only damage employee trust but also lead to legal problems such as underpayments or incorrect social insurance premium calculations.

Furthermore, payroll data contains highly sensitive personal information, including employee names, addresses, My Number (social security number), and bank account details. When entrusting this data to an external party, a complete security system at the outsourced company is a non-negotiable condition for businesses.

■ Summary

This survey revealed that 68.6% of payroll operations depend on specific internal departments.

A system that relies on specific individuals carries the risk of severe damage, such as the inability to pay salaries due to the sudden absence of the person in charge. Many companies are beginning to consider outsourcing as insurance to avoid the "worst-case scenario" that could threaten the company's survival.

For those who have actually considered outsourcing, "accuracy" and "information security" were equally ranked as the top priorities.

To maintain the stability and accuracy of payroll operations, why not consider outsourcing to a reliable external partner?
