Federal tax laws require taxpayers to maintain books of account or records to support amounts reported on tax returns. The general rule is that such books and records must be kept as long as they may be relevant to a taxpayer’s claim for a tax credit or refund or to an IRS attempt to assess additional tax for the year in question.
The specific rules relating to the length of time such books and records must be kept are quite detailed. However, the following retention periods should be used as general guidelines.
