Something wrong on a filed return? We'll fix it properly.
We prepare and file amended 1120S and 1040 amended returns to correct errors, include missed forms, or reflect changes to previously filed returns. If you need a 1040 amended return, our team can help ensure the updated filing accurately reflects your current tax information.
When to amend.
You may need to amend if you left income off, missed a deduction or credit you were entitled to, received a corrected W-2 or 1099 after filing, or had a K-1 change after your personal return went in.
Not every error needs an amendment, and some the IRS corrects on its own. We'll look at what changed and tell you honestly whether amending is worth it.
What we do.
We prepare the amended return (Form 1120-S with the amended box, or Form 1040-X for individuals), document what changed and why, and file it.
If the amendment affects shareholder K-1s, we reissue those too, since a changed 1120S usually ripples into each owner's personal return.
How it's priced.
Pricing is quoted per amendment because the scope of work depends on what needs to be corrected or updated. Whether you need a 1040 amended return or an amended 1040 form, we'll review the changes, provide a clear quote, and confirm the cost with you before any work begins.
Need to file the original return first?
Amendments require a previously-filed return. If yours never went in, see Prior-year returns instead.

We'll take it from there.
