Wisconsin Form A-222 is the Department of Revenue’s power of attorney form, and you use it by entering your taxpayer details, naming a representative, defining what they can do, signing it, and returning it to the department by email, fax, or mail. The current fillable version (revised October 2021) is on revenue.wi.gov.
Taxpayer Information
The top of the form captures who you are. What you enter depends on the entity:
- Individuals: legal name, mailing address, and Social Security number or Wisconsin tax account number.
- Corporations or partnerships: entity name, business address, and federal employer identification number (FEIN) or Wisconsin tax account number.
- Trusts and estates: trust or estate name, address, and FEIN or Wisconsin tax account number.
Match the name and identification number to what the department has on file. A mismatch can stop the form from being linked to your account.
Purpose of the Filing
Part 2 asks you to check whether you’re appointing a new or additional representative or revoking one. That choice controls which later parts you complete. Appointing someone requires Parts 3, 3A or 3B, 4, and 5. Revoking requires Parts 3A or 3B and Part 5.
Representative Information
Enter your representative’s full name, mailing address, email, and phone number. If they work at a firm, list both the individual and the firm so the department knows who actually holds the authority. Your representative doesn’t have to be an attorney, CPA, or enrolled agent; Wisconsin Administrative Code Tax 1.13 requires only that the power of attorney clearly identify the person by name.1Wisconsin State Legislature. Wisconsin Administrative Code Tax 1.13 – Power of Attorney Anyone you trust can be named, though a tax professional will be better equipped for audits or disputes.
Full Authority or Limited Authority
Part 4 defines what your representative can and cannot do. You choose one of two options.
Full authority lets the representative act on any matter before the department that you could handle yourself, including receiving confidential tax information across all tax types.
Limited authority means you check only the specific categories they need: income or franchise taxes, sales and use taxes, employer withholding, excise taxes, pass-through withholding, property taxes, or nontax debt. An “Other” box covers anything outside those categories.
Each category has an optional field for specific periods. Leave it blank and the representative has authority for all periods, past, present, and future, for that tax type.2Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Instructions Fill in years, quarters, or months only when you want to restrict them. Writing “2023, 2024” limits the representative to those tax years.
If you want different scopes for different people (full authority to your accountant, sales-tax-only access to a bookkeeper), file a separate Form A-222 for each.2Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Instructions
Who Signs
The form isn’t valid without a taxpayer signature. Who signs depends on entity type:
- Individuals sign personally. On a joint return where both spouses want the same representative, both spouses must sign.2Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Instructions
- For corporations and similar entities, an officer or other person with authority to bind the entity signs and certifies that authority.3Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney
- For partnerships, a general partner signs.
- For trusts and estates, the fiduciary (trustee, executor, or administrator) signs and certifies authority to execute the power of attorney.
Signature stamps and electronic signatures are accepted, so you don’t need to print and hand-sign if you’re filing digitally.2Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Instructions
Using a Substitute Form
You aren’t required to use Form A-222. The department accepts substitutes, including federal Form 2848, as long as the substitute names the representative, describes the authority granted, and carries a notarized taxpayer signature. Form A-222 doesn’t require notarization, which is one practical reason to use the state form.1Wisconsin State Legislature. Wisconsin Administrative Code Tax 1.13 – Power of Attorney
Where to Send It
If a specific department employee or unit is already handling your matter (during an audit, for example), send the form directly to them. Otherwise, use any of the three general channels:
- Email: DORPOA@wisconsin.gov
- Fax: 608-267-1030
- Mail: Mail Stop 5-77, Wisconsin Department of Revenue, PO Box 8949, Madison, WI 53708-8949
Email and fax are the fastest. The department doesn’t publish a processing timeframe, so if a representative needs access before a conference or appeal, submit well in advance and follow up with the employee on your case.2Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Instructions
What Your Representative Can Do After Filing
Once processed, your representative can contact the department, request information, and act on the tax matters you specified. One limitation matters here: computer-generated notices, such as a Notice of Amount Due or a refund offset notice, still go only to the taxpayer.3Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Your representative won’t automatically get copies.
The workaround is My Tax Account, the department’s online portal. If you authorize your representative for online access through MTA, they can view most notices and account activity there. Filing Form A-222 by itself doesn’t grant portal access; that’s a separate step inside your MTA account. Without it, the representative has to request copies from whoever is handling your case.
Naming a representative doesn’t shift your own responsibility. You’re still required to file returns and pay taxes on time.
Revoking or Replacing a Representative
You can end a representative’s authority at any time by filing a new Form A-222 with the revocation box checked in Part 2. Complete Parts 3A or 3B to identify the person being removed, sign Part 5, and submit through the same channels.2Wisconsin Department of Revenue. Form A-222 Wisconsin Tax Power of Attorney Instructions
Appointing someone new does not automatically revoke an existing representative. Filing a new Form A-222 for a different person adds that person alongside the current one. To replace a representative, file both a revocation for the old authorization and an appointment for the new one. When the department processes a revocation, it also removes the former representative’s access to My Tax Account if that access had been granted.
When You Don’t Need Form A-222
Not every interaction with the department needs a power of attorney on file. Your representative can attend a conference or meeting with you in person and participate without one; the same goes for corporate taxpayers bringing a representative along with an officer or authorized employee.1Wisconsin State Legislature. Wisconsin Administrative Code Tax 1.13 – Power of Attorney Court-appointed fiduciaries such as trustees, receivers, guardians, and estate administrators generally don’t need one either, because their authority comes from the appointment itself.
You need the form once your representative has to deal with the department on their own: requesting records, responding to notices, or negotiating on your behalf when you aren’t there.
