Our Story

Built From Service.
Grounded in Accuracy.

Source One Tax Services was founded with a clear purpose: give everyday people and business owners access to the same quality tax preparation that was once reserved for those who could afford big firms. What started in Totowa, NJ has grown into a trusted practice serving clients across three states.

We are a veteran-owned business, and that background shapes everything about how we work. Attention to detail. Accountability. Showing up with precision when it matters most — especially at tax time. We don't cut corners, we don't upsell services you don't need, and we don't leave questions unanswered.

Every client gets the same commitment: a return that's done right, a team that knows your situation, and a firm that will still be here next year when you need us.

Proud to Be Veteran-Owned & Operated

Our founder served, and that experience never left the building. The values instilled through military service — discipline, precision, integrity, and commitment to those we serve — are the same values we bring to every tax return, every client conversation, and every filing deadline.

Why Clients Choose Us

What We Stand For

Four commitments that have defined this firm since the day we opened.

Years of Experience
We've seen tax law change, clients grow, and filing situations evolve. That depth of experience doesn't come from a search result.
All-State Coverage
If you live in one state and work in another, we know the rules for both. Multi-state filing is standard practice here — not a specialty surcharge.
Veteran-Owned & Operated
Military service instills standards that translate directly into tax work: accuracy, accountability, and no room for shortcuts. You get that every time.
Free Prior-Year Return Review
Bring us last year's return at no charge. If we find errors or missed deductions, we'll tell you plainly — with no obligation to move forward.

Our Approach

We Don't Just File.
We Prepare You.

Tax preparation is a year-round relationship, not a once-a-year transaction. We take the time to understand your situation, explain what we're doing and why, and make sure you leave knowing more than when you walked in.

Plain-language explanations. We don't hide behind tax jargon. If something affects your return, we tell you in plain terms.
Responsive communication. Questions don't wait until April. We're available when you need answers, not just during filing season.
Bilingual service available. We serve clients in English and Spanish — whichever language makes you most comfortable.
Secure document handling. Your documents are handled through our secure client portal — no email attachments, no loose paper trails.
No Cost. No Obligation.
