国税局 IRS 提醒纳税人保护税务信息：申领身份保护 PIN 可防冒名报税，宜在 11 月中旬系统维护前办理
美国国税局（IRS）10 月 22 日发布第 IR-2026-127 号新闻稿，提醒纳税人防范税务身份盗窃：妥善保管国税局网上账户的登录信息，并申领一枚「身份保护个人识别码」（IP PIN），可有效阻止他人冒用自己的社会安全号或个人纳税人识别号报税。
IP PIN 是一组六位数字，仅纳税人本人与国税局知晓。在报税表上填入这组号码，等于为税表加了一道验证锁：没有正确 PIN 的联邦报税表将无法以该纳税人的名义提交。任何纳税人都可以主动申领 IP PIN，即使本人当年并无报税义务也可办理。
国税局特别提示，计划在 2027 年初抢早报税的纳税人，应在今年 11 月中旬网上系统进入年度维护停机之前完成 IP PIN 申领；系统通常于次年 1 月中旬恢复开放。已持有 IP PIN 者，每年会收到国税局寄发的新号码，报税时须使用当年号码。
除申领 IP PIN 外，国税局建议纳税人通过其「个人网上账户」查看本人的报税记录、退税状态与付款信息，并切勿与任何人分享登录凭据。国税局强调，该局绝不会通过电话、电邮、短信或社交媒体向纳税人索要 IP PIN，接到此类联系即为诈骗。
国税局局长 Frank J. Bisignano 表示，保护敏感财务信息是防止未授权访问税务信息与国税局网上服务的关键，保管好账户凭据并申领 IP PIN，能帮助纳税人阻止税务身份盗窃、更安心地完成报税。
IRS Reminds Taxpayers to Protect Tax Information: Get an Identity Protection PIN Before Mid-November System Maintenance
The Internal Revenue Service reminded taxpayers on October 22 (IR-2026-127) to protect their information from tax-related identity theft by safeguarding their IRS online-account credentials and obtaining an Identity Protection PIN (IP PIN).
An IP PIN is a six-digit number known only to the taxpayer and the IRS. It prevents someone else from filing a federal tax return using another taxpayer's Social Security number or individual taxpayer identification number (ITIN). Taxpayers may request an IP PIN as a proactive protective step even if they are not required to file a federal tax return.
The IRS noted that taxpayers who plan to file early in 2027 should request an IP PIN before the online system becomes unavailable for annual maintenance in mid-November. The system is generally available again beginning in mid-January.
Taxpayers can securely access their IRS Individual Online Account after verifying their identity to view recently filed returns, refund status, payments, tax records and notifications, and they should not share their sign-in information with anyone. The IRS will never call, email, text, or contact taxpayers through social media to request their IP PIN.
“Protecting sensitive financial information is essential to preventing unauthorized users from accessing confidential tax information and IRS online services,” said IRS Chief Executive Officer Frank J. Bisignano. “By safeguarding their online account credentials and obtaining an IP PIN, taxpayers can help stop tax-related identity theft, file their tax return with greater confidence, and know they have done what they can to protect themselves from bad actors.”
