Services
Three service lines. Every engagement starts with a free consult and a written scope. Plans and starting prices are on the Pricing page.
01 · Tax
Business returns require a retainer at engagement signing.
02 · Advisory
Advisory work is scoped up front so you know what the memo will cover before it starts.
03 · Bookkeeping
Monthly fees depend on transaction volume. See Pricing.
Pricing
Every plan includes the same work, done by a CPA. The plans differ in speed, access, and how much planning comes with it. Standard plans show a starting price. Priority and Preferred are quoted after a free 15-minute consult and a review of your prior-year return or books. Every price is confirmed in writing.

About
Groen, CPA LLC is a single-owner firm in a small town in Iowa, offering tax, advisory, and bookkeeping to families and small businesses.
Skyler Groen is a Certified Public Accountant. He began his career in tax at RSM US LLP. The firm takes on a limited number of clients each season so every client gets the owner's attention.
Why I started the firm
At big accounting firms, I saw loyal, long-time clients told to accept a 100% price increase or pound sand. Their follow-ups were ghosted. I didn't think that was right, and I saw an opportunity to serve small business owners with high standards.
Where I come from
I'm a third-generation entrepreneur. My grandfather and father were construction contractors. I grew up knowing my family built half of the small town I was raised in, and I wanted to serve businesses like theirs: the lifeblood of their communities, invested, literally and figuratively, in everyone's success.
My dad knew construction, but he didn't have someone to help him with the numbers and the books. If he had, I might be the third generation running the business. Now I get to help people keep businesses in families by helping families get better at business.

Privacy
What information this website and the firm collect, how it's used, and how client information is protected.
Effective October 22, 2026
Groen, CPA LLC is a CPA firm in Adel, Iowa, owned by Skyler Groen, CPA. This policy covers groencpa.com and the information you share when you book a consultation or email the firm. Questions about it go to contact@groencpa.com. See also the Terms of use.
To respond to you, schedule and hold your consultation, decide whether the firm can help, keep the records the firm is required to keep, and keep the site secure. Information is never sold or rented, and it isn't added to marketing lists or shared for anyone else's marketing.
Once you become a client, your tax return information is protected by federal law. Section 7216 of the Internal Revenue Code limits how a tax preparer may use or disclose it without your written consent. The firm follows the FTC Safeguards Rule, maintains a written information security program, and is bound by the confidentiality rules that apply to Iowa CPAs. Your engagement letter describes how your information is handled during the engagement.
Please don't send Social Security numbers, tax documents, or account numbers by regular email or through the booking form. If you become a client, you'll be given a secure way to share documents.
If you contact the firm but don't become a client, your information is kept only as long as needed to respond and for ordinary business records. Client records are kept for the periods required by federal rules and professional standards, as described in the engagement letter, then securely destroyed.
The firm uses administrative, technical, and physical safeguards to protect the information it holds, including encryption and multi-factor authentication. No system is perfectly secure. If a breach affects your information, you will be notified as the law requires.
You can ask what information the firm has about you, ask for a correction, or ask that inquiry information be deleted, subject to records the firm must keep by law. Email contact@groencpa.com.

Terms
The ground rules for using this website, and what it does and doesn't mean to contact the firm.
Effective October 22, 2026
By using groencpa.com, you agree to these terms. If you don't agree, please don't use the site.
Groen, CPA LLC is a CPA firm in Adel, Iowa, owned by Skyler Groen, CPA. Licensed by the Iowa Accountancy Examining Board.
Visiting this site, emailing the firm, or booking a consultation does not make you a client. A client relationship begins only when you and the firm both sign an engagement letter describing the work, timing, and fees. The firm may decline any engagement.
Everything on this site, including the filing dates, is general information. It isn't tax, accounting, legal, or financial advice for your situation, and you shouldn't act on it without advice from a qualified professional who knows your facts. Tax law and due dates change, and the site may not reflect the latest changes.
The 15-minute consultation is free. It's a conversation to understand what you need and whether the firm is a good fit. It doesn't create an engagement, and nothing said in it is advice to rely on. The firm may change or end this offer at any time.
Starting prices on the Pricing page, and any quote given after a consult, are not an offer. Your plan and price are set only in a signed engagement letter, and prices may change before then.
Sending information through the booking form or by email doesn't make you a client or obligate the firm to act on it. The firm handles it as described in the Privacy policy. Please don't send Social Security numbers, tax documents, or account numbers before you're a client.
Links to Calendly, LinkedIn, and other sites are provided for convenience. Those sites have their own terms, and the firm isn't responsible for their content or practices.
The Groen, CPA name, seal, photographs, and site content belong to Groen, CPA LLC. You may view and share links to the site, but please don't copy or reuse its content or images without written permission.
The site is provided as is. The firm works to keep it accurate but doesn't guarantee that it is complete, current, or always available.
To the fullest extent the law allows, Groen, CPA LLC isn't liable for any loss or damage that results from using this site or relying on its content. This doesn't limit the firm's obligations to clients under a signed engagement letter.
