Last year, a Shenzhen seller in the declaration of the JCT system was determined to be "abnormal login", 3 months of hard work all for nothing. Later it was found that the team frequently operated the background with domestic IP to trigger the wind control - which exposed an industry subterfuge:The IP recognition mechanism of the Japanese tax system is far more sensitive than expected.. The use of native residential IP proxies is a central tool for solving just such problems.
I. Why is JCT verification always stuck in the last step?
The Japanese National Tax Agency's system records the IP traces of each login. Bulk registration with a data center IP is like using the same key to open all convenience stores in Tokyo, which is bound to trigger an alarm. Last year, data showed that JCT applications submitted using non-local IPsRejection rate as high as 62%, while the native residential IP pass rate can be up to 91%.
ipipgo offers static residential IPs in Japan, directly from home broadband in Osaka and Nagoya. We once helped a Guangzhou seller to solve the verification problem: after he switched to ipipgo's Tokyo residential IP, the original application for a legal entity number, which had been stuck for 2 weeks, passed the audit of the National Tax Agency in 3 days.
Second, dynamic VS static IP hands-on comparison (with scenario table)
business scenario | Dynamic Residential IP | Static Residential IP |
---|---|---|
Initial registration of tax ID number | Suitable (need to work with multiple accounts) | inessential |
Daily tax returns | Risk of trajectory anomalies | Recommended |
ACP Customs Clearance Operations | May affect logistics data | required item |
Invoice system maintenance | Causes calibration to fail | best option |
Focused Reminder:JCT tax ID number is tied to a fixed business address. When using ipipgo static IP, it is recommended that you select a region that corresponds to the place where your company is registered (e.g., if you are registered in Osaka, select Kansai IP).
Three Steps to Build a Compliance Verification Channel
Step 1:Log in to the ipipgo console and filter the "Japan - Static Residential IP" tab.
Step 2:Precise location by zip code (e.g. 108-0075 for Minato-ku Tokyo)
Step 3:Fixed IP binding in the tax system, it is recommended to work with the fingerprint browser to do environmental isolation
After a Hangzhou seller operated according to this process, the pass rate of import consumption tax declaration increased from 53% to 89%. the key point is:Maintain consistency of interaction with IRS systems with fixed IPsThe
Fourth, common stepping point real-time mine avoidance
Pit Point 1:Misuse of airport IP leads to correlation
Last year, a seller used 10 dynamic IPs to register tax IDs at the same time, and all of them were determined to be "the same operating entity". It is recommended to use ipipgo'sExclusive Static IP + Multi-browser ProgramThe
Pit Point 2:Ignoring IP timeliness
Some tax interfaces in Japan detect the length of IP usage. Temporary IPs are easily recognized as proxies, while ipipgo's IP rental period can be freely set (minimum 1 month).
V. Key questions and answers
Q: What if I have already triggered the wind control?
A: Immediately deactivate the existing IP and replace it with a brand new residential IP through ipipgo. it is recommended to cooperate with the fine-tuning of the information of the legal person (e.g. updating the contact phone number) for the second declaration.
Q: How can I verify if my IP is included in the tax system?
A: Use ipipgo's "IP Reputation Check" function to check the IP's record in the blacklist database. Quality IPs should have a purity score of 85 or higher.
Q: Can one IP be used for multiple subsidiaries?
A: Absolutely prohibited. Even if different legal entities, sharing IPs can lead to affiliate review. ipipgo supports the configuration of independent IP pools by number of subsidiaries.
Special reminder that the Japanese National Tax Agency has recently upgraded its anti-fraud system.Verification of IP affiliation and business address consistency will be mandatory from 2025 onwards.. Use ipipgo's zip code locator feature to target a pool of matching residential IPs in advance. New users can sign up now to receive a 3-day Tokyo/Osaka static IP trial access, and are advised to complete the test before the filing season.
