Why this feels so hard
“I’m the executor and don’t want to mess up the estate’s tax return.”
“Do I need to file a 1041 if the estate had no income?”
“I procrastinated and now the deadline is near—help.”
Estate and trust taxes involve Form 1041 (fiduciary return), possible Form 706 (estate tax), Form 709 (gift tax), K-1s to beneficiaries, EIN setup, and Illinois filings. The rules differ from a personal 1040, and decisions you make now can affect beneficiaries later.

Benefits you can feel
On-time, error-checked filings
Every return goes through a defined quality review before we e-file. That means fewer delays and a smoother wrap-up for the estate or trust.
K-1s done right (no surprises later)
Beneficiaries receive clear, accurate K-1s and simple guidance on what to expect, reducing confusion and follow-up calls.
Attorney & advisor coordination
We work directly with your attorney and financial advisor so you’re not stuck as the go-between.
Secure, simple document flow
Upload sensitive files through our encrypted portal; track progress without printing or mailing.
Local knowledge, Illinois included
We handle Illinois fiduciary returns and local issues common in Will & Cook Counties.
How it works (and when)
Discovery & EIN Review (1–2 business days)
We confirm roles (executor/trustee), obtain or review the estate/trust EIN, and map which forms apply (Form 1041, final 1040, 706/709 if needed). If timing is tight, we discuss extensions.
Document Intake & Analysis (5–10 business days)
You’ll receive a simple checklist. We pull income statements (1099s), asset details, valuations, prior returns, and legal documents (will/trust). We confirm fiscal-year choices and Illinois requirements.
Preparation, QA & Coordination (5–10 business days)
We prepare the return(s), generate draft K-1s, and coordinate questions with your attorney/advisor. A second preparer reviews for accuracy before you approve.
E-File & K-1 Delivery (same day after approval)
We e-file eligible returns, provide filing confirmations, and deliver beneficiary K-1s. If an extension is prudent, we file it and set milestones so nothing slips.
Note: If you “started late,” we can file timely extensions to protect you while we finish the work.

What to gather (starter checklist)
- Death certificate, Letters of Office (executor/trustee)
- Trust agreement / will and any amendments
- EIN letter, prior 1040/1041 (if any)
- Asset list and date-of-death values; sale closing statements

Key filing timelines (typical, not legal advice)
- Form 1041 (fiduciary return): Generally due April 15 for calendar-year estates/trusts (or 5½ months after fiscal year-end). Extensions available.
- Form 706 (estate tax): Due 9 months after date of death; 6-month extension available.
- Form 709 (gift tax): Due April 15 for prior year gifts; extensions available.
- K-1s to beneficiaries: Delivered after 1041 is finalized so recipients can file accurately.
