How it begins
A Case Evaluation: we review the circumstances behind your tax problem, identify important filing or record gaps, and assess potential IRS or state resolution options before recommending a course of action.
Published investment
Individual Case Evaluation from $1,500
If you proceed with tax resolution services, your Case Evaluation investment is credited in full toward those services. Business matters are separately scoped. No particular IRS outcome or debt reduction is guaranteed.
Who it is for
- People planning retirement income, inherited assets, or a wealth transfer
- Owners planning a business succession or ownership transfer
- Executors, trustees, beneficiaries, and families handling an estate or an existing trust
How it begins
Retirement, estate, and trust work follows a process suited to its scope, records, and deadlines, coordinated with your attorney and financial advisor.
Published investment
Determined after assessment
We explain the support we recommend, what it includes, and the investment. You do not need significant wealth to start here. Your attorney handles legal advice, estate documents, and legal administration.
You do not need to own a business or buy ongoing accounting to get help with an IRS matter.
One licensed CPA firm. One relationship, managed for you.
Why Corridor
A firm built around the work in front of you.
Business accounting, tax resolution, and retirement, estate, and trust work each call for different experience. Corridor Consulting brings that experience together in one licensed CPA firm and manages the relationship for you.
The right experience for the work
We staff each engagement with professionals whose experience fits it, whether that is monthly accounting, an IRS matter, or an estate or trust.
One relationship, managed for you
Your engagement is with the firm. A designated client manager coordinates questions, documents, and requests, so you are not chasing answers.
Clear responsibilities
Each engagement states what we handle, what you handle, and what your other professionals handle, before the work begins.
Coordination with your professionals
We work alongside your attorney, financial advisor, and fiduciaries. Attorneys handle legal advice, estate documents, and legal administration.

What clients say about working with us.
-
We faced some medical related back-tax issues that were only made worse by another company. After that experience, I was hesitant to trust anyone again, but James at Corridor Consulting changed that. We took a leap of faith with him, and I’m so glad we did. There’s a saying that a good accountant will save you more than they cost, and James absolutely proved that. He gave us peace of mind and an affordable solution to a problem that had felt like a burden for far too long.

I've looked for a CPA that fit my needs for 2 months, and was starting to get gray hairs. James was super welcoming, enthusiastic, and quick to share that he had understanding. Whether that was with my needs or something adjacent, demonstrating a basic understanding of my industry, or mentioning random, one off ways that he can also help.
James seems to do this for the love of the game, and all the right reasons. I'm excited to begin working with him.

Great experience with Mr. James. It is hard to find a CPA who not only has great knowledge and expertise, but also has the willingness to do his best for his clients. He will thoroughly help his clients understand and navigate through complex tax situations such as tax debt, collections, crypto, and any other scenarios that may have multiple, nuanced options available to the clients. I highly recommend working with Mr. James, especially if you have complex tax issues.

I had some issues with old tax returns and was new to the area. Checked around and found Corridor Consulting. James was great! Helpful, friendly, timely. Took care of it all and I always knew what to expect and what was going on. Great service and support.

I've been using Corridor for a few years now for all my tax needs and they've been great. James responds quickly to all my questions and they've been meticulous and thorough in processing my returns every year.

Our process
Three steps to the right fit.
Each engagement begins with understanding your situation, so the scope, responsibilities, and investment are clear before work begins.
-
Tell us what you need
Complete the short questionnaire and select the service that best describes your situation.
-
Have a Discovery Chat
Schedule a complimentary 30-minute conversation. We review your needs, the states involved, complexity, and fit.
-
Understand the next steps
We explain the recommended scope, who is responsible for what, and the investment, so you can decide whether to engage us.
The Discovery Chat does not establish a client relationship or provide individualized tax, accounting, legal, or investment advice.
Strategic insights
Recent thinking from the firm.
Questions
Before you start.
Straight answers to what people ask before a Discovery Chat.
Do I need to own a business to work with you?
No. We help individuals and businesses with IRS matters, and we help retirees, people planning a wealth transfer, executors, trustees, beneficiaries, and families. Business Solutions is a separate service for owners and self-employed people.
Can you help with an IRS notice or unfiled returns?
Yes. Select Tax Resolution in the questionnaire. We review the facts, records, compliance needs, and possible next steps. Available options depend on your circumstances, and no particular IRS outcome or debt reduction is guaranteed.
Do you help with retirement tax planning?
Yes. We provide tax guidance for retirees and people planning retirement, including retirement income, inherited assets, and wealth transfer. We coordinate with your other professionals as appropriate. We do not provide investment management.
What if I am an executor or responsible for an existing trust?
Select Estate, Trust & Legacy in the questionnaire and describe your role. We discuss the records, tax filings, accounting needs, states involved, and the support that fits. Your attorney handles legal advice and legal administration.
Will you work with my attorney, financial advisor, or bookkeeper?
Yes. We coordinate with attorneys, financial advisors, bookkeepers, and other professionals as appropriate. The proposed engagement states our responsibilities and the work others handle.
Who will I work with?
You engage Corridor Consulting as a firm. We assign professionals whose experience fits your situation, and a designated client manager coordinates questions, documents, and requests throughout the engagement.
Do you work with clients outside Iowa?
Yes. Corridor Consulting is an Iowa CPA firm headquartered in Cedar Rapids, and we work with clients nationwide, in multiple states. Meetings are remote. During the Discovery Chat we review the states involved, complexity, and scope to confirm the fit.
What happens during the complimentary Discovery Chat?
After the questionnaire, you schedule a 30-minute meeting on Google Meet, with phone dial-in available. We discuss your needs, complexity, fit, and next steps. The conversation does not establish a client relationship or provide individualized tax, accounting, legal, or investment advice.
How are scope and pricing determined?
We review what you need, then explain the recommended support, responsibilities, and investment before you engage us. The starting process depends on the work. Ongoing Business Solutions begins with the 90-day Pathway to Prosperity™ onboarding, and other services follow processes suited to their scope and deadlines.
