Amended Returns — Marion Tax Service, Oradell NJ

A filed return isn’t set in stone. If a prior return missed income, overstated or understated a deduction, used the wrong filing status, or didn’t reflect a corrected 1099 or K-1, it can be amended. Marion Tax Service prepares the federal Form 1040-X (or 1120-X for corporations) and the matching New Jersey amendment.

Just as important, we’ll tell you when amending isn’t worth it — a tiny change that costs more to file than it recovers, or one that simply isn’t necessary. The goal is the right outcome, not extra paperwork.

What’s Included

Amended-return service covers the full correction:

  • Form 1040-X amended individual return preparation
  • Form 1120-X / 1120-S amendment for corporations where needed
  • Matching New Jersey amended return
  • A clear before-and-after of what changes and why
  • Refund-claim timing within the IRS statute of limitations
  • Documentation to support the change if the IRS asks
  • An honest call on whether amending is worth it at all

Who It’s For

Amending makes sense in specific situations:

Missed Income or Forms

Filers who received a late or corrected 1099, K-1, or W-2 after filing.

Missed Deductions or Credits

People who later realize they left a real deduction or credit on the table.

Filing-Status Fixes

Returns filed with the wrong status or a dependent issue to correct.

Business Corrections

Companies that need to fix a prior 1120-S, 1120, or 1065 figure.

Why Marion Tax Service

Amendments are judgment calls as much as paperwork — whether the change is worth filing, whether it’s still within the refund window, and whether it invites a second look. 50+ years of experience guides that call.

We handle the federal and New Jersey amendments together and document the change so it stands up if the IRS reviews it.

Frequently Asked Questions

How long do I have to amend a return?
To claim a refund, you generally have three years from the original filing date or two years from when you paid the tax, whichever is later. After that the refund is lost. We confirm you’re inside the window before filing.
Will amending trigger an audit?
Amending a return for a legitimate reason does not automatically cause an audit. We make sure the change is well-documented and correct, which is the best protection either way.
How long does an amended refund take?
Amended returns are processed more slowly than originals — often several months. The IRS provides a ‘Where’s My Amended Return’ tracker, and we’ll set the right expectation up front.
Is it always worth amending?
No — and we’ll tell you. If the change is tiny or the refund is smaller than the cost and hassle of filing, we’ll say so. We only recommend amending when it actually benefits you.
