What do you like best?
We use PDFfiller primarily for tracking and completing registration forms for the advanced trainings we provide to mental health professionals across the country. Manually managing these forms was a nightmare as our business started to grow. Once we started using PDFfiller, it began incredibly easy and hassle free to monitor who was registered for which trainings and when. the integrated PayPal and Stripe systems make it super easy to allow customers to pay registration fees immediately and we are notified as soon as that happens. Also, PDFfiller offers a digital fax line. In today's day and age, we are completely wireless and adding a hardwired fax line would have been such a pain. For 10 bucks we are able to digitally send and receive faxes which is very helpful when dealing with physicians and other medical providers.
What do you dislike?
We have only had one real issue with PDFfiller. At some point a few months ago, we had some issues with the PayPal/Stripe payment integration. We were unable to send receipts to our customer which was rather frustrating for us and them because of the amount of money people spend to some to our trainings. I reached out to someone at PDFfiller and a manager responded the next business day and said they would get in touch with the team who handles that part to get it fixed. Though I did not hear back, within a week or so the problem was fixed.
Recommendations to others considering the product:
Do it. It is well worth the price for what you are getting.
What problems are you solving with the product? What benefits have you realized?
Sending and receiving faxes through this program is a lifesaver. I am able to access them anywhere at any time whether I am in the office or out of town. It's also a great organizational tool for tracking out "link to fill" forms.

You may also contact your local Social Security office. Stimulus checks were also sent to some recipients of Veterans Affairs or Railroad Retirement Board benefits. If you did not receive your check, call 1-800-827-1000 for the VA, 1-877-772-5772 for the ROB, or contact your local office.
Cases can go back to IRS Appeals: Remember, the only way to respond to a Notice of Deficiency is to file a timely petition in U.S. Tax Court. Fortunately, though, that does not mean the case will necessarily be decided in court. An IRS lawyer will file an answer to the taxpayer's petition.
Cases can go back to IRS Appeals: Remember, the only way to respond to a Notice of Deficiency is to file a timely petition in U.S. Tax Court. Fortunately, though, that does not mean the case will necessarily be decided in court. An IRS lawyer will file an answer to the taxpayer's petition.
A notice of deficiency, also called a statutory notice of deficiency or 90-day letter, is a legal notice in which the IRS Commissioner determines the taxpayer's tax deficiency. A waiver to allow the taxpayer to agree to the additional tax liability. A statement showing how the deficiency was computed.
It is important to act quickly if you have received a tax deficiency notice because the IRS can include court charges in the balance you owe, and interest and penalties continue to accrue. If you agree with the notice, you must sign the included form and send it back. There is no need to file an amended return.
Taxpayers must respond to a notice they do not agree with. They should mail a letter explaining why they disagree to the address on the contact stub at the bottom of the notice. Include information and documents for the IRS to consider and allow at least 30 days for a response.
Simply sign Form 5564, Notice of Deficiency Waiver and send it back to the government agency. If you agree but have additional income, expenses, or credits to claim, you'll need to amend your original tax return with Form 1040-X.
Stand your ground. You may receive a notice stating that the IRS has made a change or correction to your tax return. Review the information and compare it with your original return. If you don't agree with the notice, you still need to respond typically within 30 days (or 60 days if you live outside the United States).
