上面说是 “File Form 843 (with attachments) with the IRS office where your employer's Forms 941 returns were filed. You can locate the IRS office where your employer files his Form 941 by going to Where to File Tax Returns.”
我点进去以后 找到了 Mailing Addresses for Forms 941, 但是我发现有好几种 Form 941:
Form 941 Employer's Quarterly Federal Tax Return
Form 941-PR Employer's Quarterly Federal Tax Return (Puerto Rican Version)
Form 941-SS Employer's Quarterly Federal Tax Return - American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the Virgin Islands
Form 941-SS which does not include a payment
