For begonias grown in the ground the steps are as following:
1) Dig up the plants when the foliage had faded or after first light frost. Don't leave them out too late in the fall since hard freezes can kill them.
2) Spread begonia clumps on newspaper and leave this in a sunny area until dry. Once they are dried cut away any remaining foliage and gently shake off excess soil. The big factor is making sure they are dry before storage so they don't get moldy.
3) You can dust them with sulpher powder to prevent fungal growth over the winter. Wrap each tuber in a paper bag or newspaper and store in a cardboard box in cool, dark, dry location.
If your begonias have been grown in pots, you can leave them in the pots as long as they stay dry. Put the pots in a cool, dark, dry location.
Wax begonias in pots can just be brought indoors and treated like houseplants during the winter months.
