Your Tax Prep 2020 Checklist – For Next Year’s Filing

While there may still be some time before the tax filing deadline of April 15th, it is important to have all of your tax documents in order ahead of time. Gathering all of the necessary forms and documents can be complicated and time-consuming. We’ve put together a tax preparation checklist for next year’s tax filing that compiles the information into one convenient resource.

Below is a checklist of the most common documents tax filers may need in the upcoming year. Not all of them will be applicable, but the comprehensive list is there to help make filing easier.

Apart from the items listed, it is also helpful to have a copy of last year’s tax returns included with other documentation. Our checklist includes a broad list of forms and documents that may be needed to file next year’s taxes.


Additional Considerations 

Other things to consider include itemized deduction lists for things like charitable donations, personal work expenses, and work-related meal costs. Many of these things can be at least partially deducted.  

To avoid having to file for an extension or make a tax amendment, be sure to thoroughly go through your taxes ahead of time. Comparing this year’s documents to the previous years’ tax return can help to minimize errors. This also helps to avoid concerns in the event of a state or federal audit.

If you keep books electronically, consider printing out your records and checking them against existing documentation. Also, be sure to follow up with any agencies that provide tax documentation to ensure all documents are received in a timely fashion. By following our checklist and keeping organized, next years’ filing will be much easier.
