Rima vs. PitBullTax: Tax Resolution Case Prep Compared

Short answer: PitBullTax is tax-resolution software for managing a collection case, including transcripts, resolution analysis, forms, client communication, and billing. Rima focuses on the preparation work before a practitioner approves a case document: it reads client records, drafts selected collection forms, and flags gaps for a case manager and enrolled agent (EA) to review. Rima does not make the final resolution decision or file forms with the IRS.

They address different parts of the work. Firms that use PitBullTax can keep it as their case system and consider Rima for document-to-draft preparation; using both does not imply a native technical integration.

What PitBullTax does—and what its AI can do

PitBullTax is built around managing tax-resolution matters. Its published capabilities include retrieving account, wage and income, and return transcripts with the appropriate authorization; presenting transcript information in readable reports; evaluating resolution options such as Offer in Compromise (OIC), Installment Agreement (IA), and Currently Not Collectible (CNC); and populating a range of IRS forms from case data. The vendor also describes a client portal, file sharing, reminders, e-signature requests, case management, and billing.

Its AI features should be part of an honest comparison: PitBullTax describes an AI companion for Internal Revenue Manual (IRM) questions, AI-assisted letter drafting, and generated form narratives. Its public materials do not describe AI that reads bank statements or pay stubs and reconciles their figures into a 433; that distinction is about what is described publicly, not a claim that the product cannot do more.

What Rima adds to the preparation step

Rima starts with source documents rather than information already entered into a case. A team uploads financial records and intake material, selects a workflow, and uses Rima to extract relevant figures and create a draft for review. Values can be checked against their source, and the workflow can flag missing records, mismatches, or inconsistencies—for example, an account listed on intake without a corresponding statement.

Drafts Form 433-F, 433-B, and 433-A (OIC) from uploaded case materials.
Links extracted values to their sources to support verification.
Flags completeness issues for a case manager to resolve.
Supports evaluation, diagnostics, and IRM research through Advisor.

These are preparation aids, not a final eligibility determination, legal or tax advice, or an IRS submission. The case manager resolves open questions and an EA reviews, edits, and approves the work before it is used. See the document automation workflow and the 433-F preparation guide for more detail.

The practical difference: who reads the source documents?

Form auto-population can carry case information to the right form fields, but that information first has to be gathered and checked: identify the relevant balance and date, calculate income consistently, reconcile records, and notice missing documentation. Rima is designed to assist with that source-document reading and first-pass preparation. PitBullTax is designed to help run the case and work with information in it. A practitioner still checks the draft and the evidence.

How a firm might use both

A firm may keep PitBullTax for case tracking, transcripts, resolution analysis, client-facing tools, and billing, while using Rima to prepare a source-backed draft for internal review. One anonymized firm with more than 300 active collection cases reported reducing 433-F preparation from about 90 minutes to about 30 minutes. Results vary by case and document quality. Read the 433-F preparation case study.

Which should you choose?

Choose PitBullTax if you need software to manage and track tax-resolution cases and its case, transcript, analysis, client, and billing tools fit your practice.
Consider Rima if staff spend substantial time reading financial documents and compiling 433 drafts, and you want that first pass prepared for human review.
Consider both if PitBullTax serves your case-management needs and you want a separate document-preparation workflow. Confirm how information will be moved and reviewed; do not assume a native integration.

A useful evaluation is to test a representative case, inspect whether reviewers can trace figures to source documents, and confirm how corrections and approvals are recorded. Keep professional judgment, final approval, and filing with qualified practitioners.

Frequently asked questions

What is the difference between Rima and PitBullTax?

PitBullTax is designed to manage tax-resolution cases, including transcripts, analysis, form population, client tools, and billing. Rima focuses on reading source documents and preparing 433 drafts and research for case-manager and EA review.

Does PitBullTax use AI?

Yes. PitBullTax describes an AI companion for IRM questions, AI-assisted letters, and AI-generated form narratives. AI capabilities can change; its public materials do not describe bank-statement and pay-stub reading to populate a 433.

Is Rima a replacement for PitBullTax?

Not for case management. Rima is focused on case preparation and review support; it does not replace PitBullTax’s case-management, transcript, portal, or billing functions. Firms may evaluate them for separate tasks.

Which forms does Rima prepare?

Rima creates drafts of Forms 433-F, 433-B, and 433-A (OIC) from uploaded records. Practitioners verify the details against original documents, resolve issues, and approve the work; Rima does not file the forms.

How much time can Rima save on 433-F preparation?

One anonymized firm with more than 300 active collection cases reported that its 433-F preparation took about 30 minutes rather than about 90 minutes. Outcomes vary with case complexity, document completeness, and the firm’s review process.

Is client data secure?

Rima is CASA certified; SOC 2 is in observation. See the security page for current security information.
