The IRS Office of Professional Responsibility (OPR) has explained how taxpayers and their representatives can use a durable power of attorney when a taxpayer becomes physically or mentally incompetent and cannot sign an IRS Form 2848, Power of Attorney and Declaration of Representative, to authorize representation. A pre-existing durable power of attorney can grant authority, but the representative must still file a Form 2848 on the taxpayer's behalf to specify the tax matters involved. (OPR Alert Issue Number: 2026-15, 5/19/2026)
But what happens when the
taxpayer can no longer sign?
This situation arises more
often than expected, particularly with aging clients, sudden illness, or
cognitive decline. Once a taxpayer loses legal capacity, they cannot execute a
Form 2848. At that point, without prior planning, families and advisors may
find themselves unable to act on the taxpayer’s behalf in dealing with the IRS.
Durable Power of Attorney:
The Critical Backstop
A properly drafted durable
power of attorney (DPOA) can solve this problem—but only if it is in place
before incapacity occurs.
A DPOA allows an appointed
agent (attorney-in-fact) to act on behalf of the principal even after the
principal becomes incapacitated. While these documents are commonly used in
estate planning, their importance in tax matters is often overlooked.
However, not all DPOAs are
sufficient for IRS purposes.
The IRS has specific
procedural requirements under 26 CFR § 601.503 (see Publication 216). Most
standard DPOAs do not include the detailed elements required for direct IRS
representation—such as:
·
Specific tax matters (e.g., income tax, civil penalties)
·
Form numbers (e.g., Form 1040, Form 709)
·
Tax years or periods
Because of this, a DPOA
alone is typically not enough to fully substitute for Form 2848.
How It Works in Practice
Even if a DPOA lacks the
required specificity, it can still be used effectively.
The key is this:
The agent named in the durable power of attorney can complete and sign Form
2848 on behalf of the incapacitated taxpayer.
This approach bridges the
gap between the broad authority granted under state law and the IRS’s
procedural requirements.
That said, one condition is
critical—the DPOA must authorize tax matters. Ideally, it should explicitly
reference “federal taxes” or grant broad authority covering financial and tax
decisions. A generic or narrowly drafted power of attorney may not be sufficient.
What Happens Without a Valid
DPOA?
If no valid DPOA exists—or
if it is too limited—the situation becomes significantly more complex.
In those cases, the
representative may need to be appointed as a fiduciary through a court
proceeding (e.g., guardian or conservator). Only after that appointment can the
individual:
·
Act on behalf of the taxpayer, and
·
Notify the IRS using Form 56 (Notice Concerning Fiduciary
Relationship)
This process is
time-consuming, costly, and entirely avoidable with proper planning.
Practical Planning Takeaways
For practitioners advising
individuals or closely held business owners, a few best practices stand out:
·
Ensure every client has a durable power of attorney in place
before incapacity.
·
Confirm that the document explicitly includes authority over
federal tax matters.
·
Coordinate estate planning documents with tax representation
needs.
·
Educate clients that a DPOA does not replace Form 2848—but enables
it when capacity is lost.
A small drafting oversight
today can create major procedural barriers later.
The Bottom Line
Form 2848 remains the
primary tool for IRS representation—but it depends on the taxpayer’s capacity
to sign. A durable power of attorney ensures that this authority does not
disappear when it is needed most.
For tax professionals, integrating DPOA review into client onboarding and periodic check-ins is a simple step that can prevent significant complications down the road.
