How should you fill out a Power of Attorney (Form 2848) for an audit?

Cover all tax years (past and up to three years beyond the current year) and include the relevant forms. This prevents the IRS from withholding information about other years and saves time. It can also avoid the concern that you might \”tip-off\” the IRS to another year with an issue if you include it. By including every year from 2001 forward you avoid this.
