A CPA firm built to handle both the recurring accounting and the difficult tax matter.
D&J Accounting & Tax Services, Ltd. is a licensed certified public accounting firm serving businesses and individuals throughout Chicagoland since 1990. It is led by Joaquin Gonzalez, CPA.

Direct about the exposure, specific about what is achievable.
Joaquin leads D&J's accounting, tax and representation practice. Clients work with him directly: the examination strategy, the cash-flow conversation and the review of the return are not delegated to whoever is available that week.
His practice spans both halves of a company's financial life. On one side is the recurring work — QuickBooks, bookkeeping, payroll, financial statements, business and individual returns — that keeps an entity organized and its filings consistent. On the other are the corporate income-tax and payroll-tax examinations that arrive when something in those filings draws agency attention.
That pairing is unusual among small firms, and it explains the pattern in D&J's engagement history: businesses arrive for a monthly close and stay through an appeal, and other accountants' clients arrive mid-examination for a second opinion.
Joaquin's method is consistent. Reconstruct the records before responding. Test the agency's position against what the books and the law actually support. Explain the realistic range of outcomes in plain language, including the outcomes that are not available. Then document everything the position depends on.

Serving Chicagoland since 1990
D&J has spent more than three decades working with the same categories of business owner: contractors, developers, practice owners and closely held companies whose financial questions rarely fit a template.
Founded in 1990
The firm publishes 1990 as its founding year. Some external directory profiles show 1989; the discrepancy is flagged for the firm to resolve rather than smoothed over here.
Harwood Heights office
The practice operates from 4950 North Harlem Avenue in Harwood Heights, working with clients across the Chicago metropolitan area.
Two practices, one firm
Ongoing accounting, payroll and tax work alongside examination, appeal and collection representation — which is why the representation work starts from records the firm already understands.
What this site does not claim
Credentials, dates, staffing and case figures are published only after the firm confirms them against its own records. The list beside this is the current open set.
