Do you work with small businesses?

Yes. DWK Tax & Accounting specializes in serving small business owners, entrepreneurs, and growing companies who need more than basic tax compliance, including strategic advisory and fractional CFO support.

How do I schedule a consultation?

You can schedule a consultation by visiting https://dwkcpa.com/contact, calling (708) 369-0044, or emailing david@dwktaxaccounting.com.

What documents do I need for individual tax preparation?

Bring your prior year return, all income statements (W-2s, 1099s), investment and brokerage statements, rental property records, K-1s, mortgage interest and property tax documents, and any IRS or Illinois notices. After your first consultation we provide a personalized checklist tailored to your situation.

Do you handle 1099 and self-employment income?

Yes. We prepare Schedule C returns for freelancers, contractors, and sole proprietors, capturing every legitimate business deduction and calculating self-employment tax accurately. We also coordinate quarterly estimated payments so you avoid underpayment penalties the following year.

Can you prepare returns with rental property income?

Absolutely. We handle Schedule E rental income, track depreciation and improvements, distinguish repairs from capital improvements, and document passive activity losses correctly. Whether you own one rental or a small portfolio, your return reflects the full tax picture.

Do you handle investment income and K-1s?

Yes. We report capital gains and losses, dividends, interest, and income from partnerships, S corporations, and trusts reported on Schedule K-1. We also handle cost basis tracking, wash sales, and the net investment income tax where it applies.

What if I lived or worked in multiple states?

We prepare multi-state and part-year resident returns, allocate income correctly between states, and manage reciprocal agreements, including the Illinois-Iowa and Illinois-Indiana reciprocity rules, so you are not double-taxed on the same income.

A CPA, Not a Seasonal Kiosk

National tax chains process returns by volume and disappear after April 15. When your situation includes 1099 income, a rental, or a K-1, that assembly-line approach misses deductions and invites errors.

David Korzeniowski, CPA reviews your complete financial picture, identifies planning opportunities before filing, and stays available all year for life changes, IRS notices, and next-year strategy. Your return is prepared once, and prepared right.
