CPA-prepared federal and Michigan state returns for LLCs, S-corps, partnerships, and sole proprietors. Deadlines tracked. Deductions maximized. IRS representation if it's ever needed.
Business tax filing is complex — multiple schedules, entity-specific requirements, payroll and sales tax interplay, and deadlines that turn into penalties fast. As your CPA, Mindy handles your business return from start to finish so you can focus on running your business.
Book Your Free ConsultationMost Grand Rapids business owners don't realize how much their entity type, payroll, and depreciation choices shape their tax bill. If your return touches any of these areas, working with a CPA pays for itself.
Form 1120-S, reasonable salary analysis, K-1 distributions, and the payroll filings that come with the S-corp election — all coordinated with your personal return.
Single-member or multi-member, default tax treatment or an S-corp election — the right choice depends on your numbers. We run the math before the filing.
Form 1065, K-1 generation for every partner, allocation of income and deductions, and coordination so each owner's personal return ties out cleanly.
Schedule C filers — contractors, consultants, freelancers, small shops. Self-employment tax, home office, vehicle, and retirement deductions handled cleanly.
Behind on business filings? We help Grand Rapids businesses catch up, minimize penalties, and get back in good standing with the IRS and Michigan — confidentially.
Got an IRS notice or worried about a past return? As a CPA, Mindy can represent your business before the IRS and Michigan Department of Treasury directly.
Rental income, depreciation, Schedule E, and passive activity rules — owning rental property adds real complexity to your return. We handle every form so nothing gets missed.
Once your business is past a simple Schedule C, software starts to creak. An S-corp election alone introduces a separate return (Form 1120-S), a payroll filing requirement, reasonable-salary analysis, and a K-1 that flows back to your personal return. Add a partner, a vehicle on the books, inventory, or sales tax in Michigan, and the number of right answers narrows quickly.
A CPA asks better questions — the ones that surface Section 179 timing, depreciation choices that change your bottom line for the next five years, retirement plan contributions you can still make for last year, and Michigan-specific credits the software interview never asks about. The SBA's business tax guide covers the fundamentals — but the real savings live in the details that only a CPA applied year-round can optimize. That's the gap between filing a business return and filing it right.
As a tax accountant in Grand Rapids, MI, Mindy reviews every business tax return personally before it's filed with the IRS and Michigan Department of Treasury. No junior preparer, no software-only review. She signs the return she's actually read. When Grand Rapids businesses need tax accountants who also know their books and payroll, 4K is the one-CPA answer — not a team of strangers.
Business tax questions don't wait until March. When you call in August about a new hire, an equipment purchase, or a partner buyout — Mindy picks up. That's not how most firms work, but it's how 4K has worked for 28 years.
No handoffs to junior staff. No "I'll have someone call you back." You work directly with the CPA who signed your business return — every time.
If the IRS or Michigan Department of Treasury ever questions a business return we prepared, we stand behind it. Mindy can represent your business directly — you don't face the agency alone.
Business decisions don't wait for tax season. Mindy is available year-round — for entity changes, new hires, equipment purchases, and anything that shifts next year's filing.
28 five-star reviews on Google. Here's what a few business clients have to say.
"Mindy is great. I am so happy that I have someone I can trust to have my business's best interest in mind. She is very professional and goes above and beyond. I knew from the initial meeting that Mindy was going to be someone who would be awesome to work with."
"I had a complicated problem with my state unemployment taxes. I turned the problem over to these experts and they fixed a 20-thousand-dollar problem. We highly recommend this company! They are professional and know their stuff!"
"Mindy does an excellent job of explaining accounting and tax terms in a way that I can understand. As a small business owner, that helps me to make better financial decisions. I cannot imagine doing all my own accounting and am grateful to be working with someone I know I can trust."
Every business is different. A single-member LLC looks nothing like a multi-partner S-corp with payroll and sales tax. We review your situation and give you a clear, personalized quote during your free consultation — before any work begins.
S-corporations and partnerships file federal returns (Forms 1120-S and 1065) by March 15. C-corporations and most sole proprietors file by April 15 along with their personal return. Michigan business income tax follows the federal deadlines. Extensions are available but only extend the time to file — not the time to pay. We track every deadline for our business tax preparation clients in Grand Rapids.
An LLC by default is taxed like a sole proprietorship or partnership — all profit flows to your personal return and is subject to self-employment tax. An S-corp election can reduce self-employment tax by letting you pay yourself a reasonable salary and take the rest as distributions, which aren't subject to SE tax. The right choice depends on your profit level, payroll capacity, and state filing costs. We run the math for your specific situation before recommending a structure change.
Common deductions include vehicle and mileage, home office, business meals, professional services, software and subscriptions, equipment (with Section 179 or bonus depreciation), payroll and contractor payments, business insurance, and retirement plan contributions. Michigan has its own rules on certain items. Most business owners miss deductions because they don't know the category exists — we go through your full picture during tax prep to make sure nothing's left on the table.
Yes. As a CPA, Mindy can represent your business before the IRS and the Michigan Department of Treasury for any return we prepare. That includes responding to notices, gathering documentation, attending audit meetings, and negotiating outcomes. For our business tax preparation clients in Grand Rapids, audit support is part of the relationship — you don't get a bill the moment something goes wrong.
If your business is more than a single-member LLC with simple Schedule C income, the math usually favors hiring a CPA. S-corps and partnerships involve separate returns (1120-S, 1065) and K-1s. Multi-state operations, payroll, sales tax, depreciation, and inventory each carry their own rules. A CPA pays for itself by catching deductions you'd miss, structuring your filings to reduce future tax, and making sure penalties don't compound from late or wrong filings.
