This app has been a lifesaver. I have recently started a position as an Administrative Assistant and the abilities within this program make my job hassle-free. It makes filling in PDFs and requesting e-signatures as efficient as possible.

I am in LOVE with this app!! This platform provides an all-in-one service for a price you just cant beat. Without a doubt the #1 MUST-HAVE business tool that trumps all the rest. They even offer Monthly or Annually subscriptions giving the user some flexibility pricing to choose what suits them best based on their individual or professional needs. Absolutely worth every penny!!

I need fast turnarounds for information as I do not have time to convert content from other platforms. I have little time and money to do things. The PDF filler is cost effective and enables me to convert content in a matter of seconds, rather than hours in some cases.

Where do you sign on tax forms?
The signature line on the new Form 1040 is located directly below the Dependent section, almost in the middle of the form.
Does IRS accept copied signatures?
Yes. Although we prefer original signatures in ink, we will also accept scanned, copied and faxed signatures as well as original signatures in pencil.
What qualifies as a signed tax return?
What qualifies as a 'signed' tax return? To qualify as a 'signed tax return' the document must either: Be signed by at least one of the tax filers. Or, include the tax preparer's stamped, typed, signed, or printed name and SSN, EIN (Employer Identification Number), or PAIN (Preparer Tax Identification Number).
Is an unsigned tax return valid?
Whether an unsigned return constitutes a valid return such that the Service may assess tax or issue a refund. Whether a return filed without a required entry, form, schedule, or other missing information or documentation is a valid return such that the Service may assess tax or issue a refund.
What is the signature page of a tax return?
The signature page is the page that you would have signed if you didn't sign it electronically for e-filing. Sometimes, these requests only require that you print a copy of your signature page, sign and date it for the date that you e-filed the return.
Can I electronically sign my tax return?
You can sign your tax return electronically by using a Self-Select PIN, which serves as your digital signature when using tax preparation software, or a Practitioner PIN when using an Electronic Return Originator (ERO). If you're filing a joint return, each spouse uses his or her own PIN.
What happens if you forgot to sign your tax return?
If you submitted your return without signing it, all is not lost. In all likelihood, the IRS will simply send you a letter requesting your signature. And once they receive your signature, they'll go ahead and process your return. If you choose not to do this, then you will have to complete and sign IRS Form 8453.
