Employment Forms People Fax Every Day
Whether you are a new hire completing onboarding paperwork, a remote employee sending signed forms back to the office, or a small business owner reporting to a state agency, these are the documents that land in HR fax machines most often:
Required by USCIS for every new hire within 3 business days of the start date. Commonly faxed between employer locations or from remote employees to HR.
Tells your employer how much federal income tax to withhold. Filed with payroll, not the IRS. New employees submit on their start date.
Required from independent contractors and vendors paid $600 or more. Contains your SSN or EIN — secure transmission matters.
Authorizes paycheck deposits into your bank account. Includes sensitive routing and account numbers. Some employers require a voided check.
Federal law requires employers to report new hires within 20 days. Most state agencies accept fax: GA (888) 541-0521, OK (405) 557-5350, KS (888) 219-7798.
Employee consent for criminal, credit, or reference checks under the FCRA. Most forms explicitly state that fax copies are valid as originals.
Health insurance, dental, vision, and 401(k) enrollment. New hires typically have a 30-60 day window. May contain health info — consider HIPAA mode.
State equivalent of the W-4. Examples: CA DE 4, NY IT-2104, IL IL-W-4. Faxed to employer payroll alongside the federal W-4.
Who Needs to Fax Employment Forms?
New hires onboarding remotely
Your new employer sent you a stack of forms but the office is across the country. Fax your completed I-9, W-4, direct deposit form, and background check authorization back to HR from your phone or computer.
Small business owners reporting new hires
Federal law requires you to report every new employee to the state within 20 days. Many state agencies still accept fax as an official reporting method — no portal login needed.
Independent contractors submitting W-9s
A new client needs your W-9 before they can process your first payment. Fax it securely without exposing your SSN over email.
Remote employees returning signed paperwork
Your company updated its NDA, benefits elections, or emergency contact forms and needs signed copies back. Fax them from any device instead of mailing originals.
Staffing agencies processing temp workers
Temp and contract workers cycle through multiple employers. Staffing agencies rely on fax to collect and forward onboarding documents quickly between placements.
Key Deadlines for Employment Paperwork
Employment forms come with strict deadlines. Missing them can mean fines for employers and delayed paychecks for employees.
USCIS requires employers to examine identity documents and complete Section 2 by this date.
Federal law (42 U.S.C. 653a) requires reporting to the state where the employee works. Used for child support enforcement.
If no W-4 is on file, the employer must withhold at the Single with no adjustments rate.
Missing the enrollment window means waiting until open enrollment or a qualifying life event.
Under the FCRA, employers cannot run a background check without written employee consent.
Note: These are general guidelines. Deadlines may vary by state and employer. Always confirm with your HR department.

Employment Forms Fax Questions
Can I fax my I-9 form to my employer?
Yes. Your employer may accept a faxed copy for their records. The I-9 is not filed with any government agency — employers keep it on file for audits. Remote employees commonly fax I-9 forms to HR departments. Employers using E-Verify have a permanent remote document examination option available since August 2023.
Is it safe to fax forms with my Social Security number?
Fax is one of the more secure methods for transmitting sensitive tax forms like W-4 and W-9. Unlike email, fax transmissions are point-to-point and are not stored on intermediate servers. OneFaxNow also offers HIPAA-compliant faxing with encryption and immediate file deletion for maximum security.
Can employers fax new hire reports to the state?
Yes. Federal law (42 U.S.C. 653a) requires employers to report new hires within 20 days. Most state new hire reporting agencies accept fax as an official submission method alongside online reporting and mail.
