Hi @RWRDfamily! Like a lot of things related to tax law, the answer is it depends. I have included a link to the IRS recommendations below, but in general you would need to keep records for a minimum of 3 years. However, since you mention having properties, you will want to keep those records longer to figure any depreciation, amortization, and to determine the gain or loss on sale of property.
How long should I keep records?
