Which forms do I need for filing 2016 taxes for self employed sole proprietorship through SSN?

You'll notice this is a late filing. I'll be doing 2017 through TurboTax online software but I prefer to do 2016 manually for added control. 

For the 2016 year I operated an online resale business, classed as a sole proprietorship and attached to my individual SSN instead of an EIN. I never sent Estimated Quarterly Tax Payments, I did file an extension which ran its course some time ago, and I had coverage through the Healthcare.gov Marketplace for approximately 4 months. From my research, I've found that I need the following forms: 

Form 1040

Form 1040-ES

Schedule C [1040]

Schedule SE [1040]

Form 8965

Form 944

Form 2210

Please advise if I'm missing anything. 


You cannot use online software to prepare a 2016 tax return.  Only desktop software can be used for a 2016 return.  You will have Forms mode in desktop software so you can switch to Forms and see them while you work as desired.

Online preparation and e-filing for 2016 is permanently closed.

To file a return for a prior tax year

Only a 2017 return can be prepared online and e-filed. 

 If you need to prepare a return for 2014, 2015, or 2016 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)


Remember to prepare your state return as well—if you live in a state that has a state income tax.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s.  Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return.

People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

  1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
  2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
  3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
  4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
  5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
