Compare providers by the specific work and authority they will document. A platform, accounting firm, staffing provider and law firm can offer different scopes, and the category name does not establish coverage. Ask for the contract, assigned person, escalation process and evidence the provider will retain.
| Decision | Evidence to request |
|---|---|
| Which notices are included? | Covered agencies, entities, periods and exclusions |
| Who reads and logs the notice? | Named intake owner and source-linked queue |
| Who determines the response? | Authorized reviewer, qualifications and engagement scope |
| Who may contact the agency? | Activity-specific permission and representation authority |
| Who approves release? | Client approval and permitted submission owner |
| What is retained? | Request, source documents, approved response and delivery evidence |
Internal document handling does not establish representation rights. A disputed matter may need legal or tax professional advice, but the appropriate person and authority depend on the matter. Do not assume a vendor can respond merely because it receives a duplicate notice.
Compare proposed service targets separately from agency dates. No generic notice timetable, guaranteed response, penalty relief, price or provider ranking is supported by this guide. Where a provider cannot document a scope item, keep it as an unanswered buying question.
Practical questions
What should I compare first?
Compare the specific records, activities, named decision owners and evidence required for your situation.
Can a virtual or outsourced BPO team make the tax decisions?
The administrative scope described here does not include tax advice, signing, filing, payments or agency representation. Confirm any separate professional service and authority.
Do payroll software names establish capability?
No. ADP, Paychex, Paylocity, QuickBooks, UKG, Workday and Gusto identify possible source systems. Verify the actual product functions and permitted access for the engagement.
