2 Old files
Whether you have a working home office or not, chances are you have a file cabinet filled to overflowing with old files and paperwork. Most of it you don't need to keep. If you do, scan the papers and store them electronically. Then put the rest in the recycling bin (shred it first if it contains sensitive information). Tax returns should be kept for seven years; after that, you can get rid of them with a clear conscience.
