At-a-Glance: Form 2848
What Is Form 2848?
Form 2848, "Power of Attorney and Declaration of Representative," authorizes an individual to represent you before the IRS. Unlike Form 8821 which only allows viewing rights, Form 2848 grants your representative full authority to act on your behalf, including signing agreements, receiving refunds, and making tax elections.
Why You Need Form 2848
File Form 2848 when you need professional representation or can't handle IRS matters yourself:
- •You're under IRS audit and need a CPA or attorney to represent you
- •You have complex tax issues requiring professional negotiation
- •You're unable to handle IRS matters due to illness or absence
- •Your business needs authorized representatives for tax matters
