The calendar just rolled over to a new year, so it's time to start fresh with some new files. This goes for you whether you're mostly digital, mostly paper, or somewhere in the middle.
If you keep digital files, I recommend downloading pdf copies of the statements as a backup and keeping them in folders on your computer and backed up on a cloud server (I use dropbox, but there are many good options out there.). Now is the time to create new folders labeled with the new year so you'll be ready when this year's downloads are available.
If you keep paper files, now is the time to label some fresh new folders. If you have a file drawer, one good option is to keep two-year's worth of files available at a time so you can just rotate the files for the new year. One set of files will be labeled "odd" for odd years, and the other "even." When the new year rolls around, bring the new year's set of files to the front of the drawer, emptying them out by discarding anything no longer need to store and placing items for long-term storage (Check the IRS website for a reference list.) in an archive file location such as a less-accessible file drawer or a box in a closet, attic, or basement (Use plastic bins if moisture is a problem.).
Another option for paper files is my expanding file system. Each year, I start fresh with a new 19-pocket expanding file. For the first part of the year, while I'm preparing for taxes, I keep last year's file handy. After April 15th, it goes down to my basement on a shelf with 7 others. I store 7 years' worth of files (that's how long to save tax-related info) plus one expanding file for permanent information (tax returns, home repairs, major medical info, etc.). I like this system because it's easy, compact, and never has to be purged. After 7 years, the files get shredded and I can reuse the expanding file.
How will you make a fresh start with files this year?
