Where we work

Serving Chicago and greater Cook County.

We work with small businesses from every corner of the city. Everything is delivered remotely — you send us what you have, we do the work, you approve. But we know the local terrain: Illinois' flat income tax rate, Cook County's layers of local taxes, and the Chicago small-business compliance calendar that catches every new owner off guard.

If your business runs in one of these neighborhoods (or anywhere within the Chicagoland metro, including the suburbs), we're a fit.

You’re not the only one

Sound familiar? Here’s exactly what we do about it.

I have a shoebox of receipts and no idea where to start.

We start there.

Send us the shoebox. We build your books from scratch. Your first month is on us if we can’t get you current within 30 days.

My last accountant took 8 days to reply.

We answer within 4 business hours. Or that month is free.

Yes, it’s written into your invoice. We track it. You see it.

I’m terrified of an IRS audit.

We audit-proof every return before we file.

Three specific checks, every return, every time. Ask us to walk you through them on your discovery call.

What we actually do

Four services. Zero jargon. Real deliverables.

Monthly bookkeeping

The shoebox problem

Send us anything. We categorise it. You get one clean report on the 5th of every month.

Tax preparation

The 11pm-Google problem

Federal, state, local. Every deduction. We file. You approve. Nobody Googles “K-1” at 11pm ever again.

Quarterly tax planning

The “am I paying too much?” problem

Every three months we tell you exactly what to owe — and how to owe less next year.

Audit support & representation

The “the IRS just called” problem

We pick up. We prepare the paperwork. We show up with you. You are not alone in that room.

Njock Simon Ndum, Co-founder and CEO of NJ's Accounting and Tax Services
The person doing your books

Hi, I’m Njock.

I co-founded NJ’s Accounting and Tax Services because small businesses deserve an accountant who answers the email. I’m QuickBooks-certified, working on my CFO certification, and I’ve spent enough years doing this to know what a bad quarter feels like.

When you email us, I’m the one who answers. Not a receptionist, not a bot, not a junior.

Chicago-specific questions

Questions Chicago small-business owners ask us most.

Do you actually work with Chicago small businesses, or is this just an SEO page?
We work with small businesses across the Chicago metro — every neighborhood listed above, plus the suburbs. All work is delivered remotely, but we know Illinois and Cook County filing rules cold. If we don't think we're a fit, we'll tell you on the discovery call — free.
How does Illinois' flat income tax work for my small business?
Illinois uses a flat income tax rate that applies to both individuals and businesses — no brackets. For pass-through entities (LLCs, S-corps), the income flows to your personal return. We handle the calculation and estimated payments so you're never surprised at filing time.
What local taxes does Chicago add on top of the state?
Chicago layers several local taxes — personal property lease tax, Chicago use tax, and a higher combined sales tax rate that's one of the steepest in the nation. If you sell goods or taxable services within city limits, we map exactly what you owe and set the schedule so nothing slips.
Do I need to worry about Illinois' pass-through entity tax (PTE)?
If you operate as an S-corp or partnership, Illinois offers an elective PTE tax that can help you work around the federal SALT deduction cap. Whether it saves you money depends on your specific situation. We run the numbers during quarterly planning and tell you straight — opt in or skip it.
Are you a CPA firm? Do I need one for a Chicago small business?
Njock is an accountant, not a CPA — which is honestly what most small businesses actually need. If your situation calls for CPA-level representation (Illinois DOR audit, IRS field audit, complex M&A), we'll say so upfront and either bring in a CPA partner or refer you out. No ego, no upsell.
Do you have a Chicago office I can visit?
No — and we're transparent about it. We keep overhead low so we can charge $299/mo instead of $600. Every client works with us over email, video, and phone. If in-person matters to you, we'll tell you honestly on the discovery call so you can decide.
