Most Oradell filers don’t need a giant national chain — they need an experienced firm that actually understands their situation, returns their calls, and explains the result in plain English. That is exactly how Marion Tax Service works.
From a simple Form 1040 to an S-corp 1120-S with a reasonable-salary question, from quarterly estimates for a Bergen County freelancer to back taxes and IRS notices, the tax work below is all handled in house — in person at our Oradell office on Kinderkamack Road or fully virtually anywhere in New Jersey.

Many of our clients are small-business owners whose personal and business returns are tangled together — an S-corp K-1 flowing onto a 1040, a Schedule C plus a W-2 spouse, estimated payments tied to business profit. Keeping both returns with one firm means nothing falls between the cracks and your whole picture is planned together, not in pieces.
Built for Bergen County
New Jersey has its own rules — the Gross Income Tax, the Corporation Business Tax, NJ sales-and-use tax, and county-level quirks. Marion Tax Service files the federal and the New Jersey side together and keeps both compliant.
