Correspondence Audit — IRS Letter Explained

What This Is

Even though it is handled by mail, deadlines and documentation requirements are still strict.

What Happens If You Ignore It

• The IRS may disallow the item under review
• A tax adjustment may be finalized
• Penalties and interest may apply
