Tax Deadlines After a Death in Kansas: The Complete Executor Timeline

Missing a deadline in Kansas estate administration doesn't just cause inconvenience — it can extinguish a surviving spouse's tax exclusion permanently, expose the executor to personal liability, or result in IRS penalties compounding against the estate. The deadlines in Kansas are hard dates, not suggestions.

Here is the complete timeline, anchored to the date of death.

Immediate: Weeks 1–3

Death certificates. Order certified copies from the Kansas Department of Health and Environment (KDHE) Office of Vital Statistics as soon as the death is registered. The cost is $20 per certified copy. Banks, insurance companies, financial institutions, the Register of Deeds, vehicle title offices, and the IRS all require certified copies — not photocopies. Order 8 to 12.

Claim KPERS death benefit. If the deceased was a retired Kansas public employee, the $6,000 KPERS lump-sum death benefit must be actively claimed by the named beneficiary. It is not automatically paid. Contact KPERS promptly if cash is needed to cover immediate burial costs — the benefit can be assigned directly to a funeral establishment.

Locate estate planning documents. Find the original will, any revocable living trusts, and check real estate deeds for Transfer on Death designations. These determine which administration route applies.

Days 20–45: Jurisdiction and Administration Path

Determine the administration route. Calculate the net probate estate — assets without beneficiary designations, excluding assets with TOD designations or joint tenancy. If the total is under $75,000 and contains no real estate, the Small Estate Affidavit (K.S.A. 59-1507b) applies and probate can be skipped entirely. If under $75,000 but real estate is involved, a Petition for Refusal to Grant Letters may be appropriate. If over $75,000, file a Petition for Probate in the local district court.

Apply for an estate EIN. Apply through irs.gov immediately. Takes 15 minutes and is free. Required to open the estate bank account and file fiduciary tax returns.

File probate petition (if required). Pay district court docket fees (ranging from approximately $102 to $131, depending on county). Request simplified administration under K.S.A. 59-3201 to reduce ongoing court involvement.

30 Days After Letters Are Issued

File the estate inventory. Kansas law requires the executor to file a formal inventory of all estate assets with the district court within 30 days of the issuance of Letters of Administration. The inventory must list each asset and its appraised value.

Months 2–6: The Creditor Window

Publish Notice to Creditors. The executor must publish a Notice to Creditors in a local newspaper for three consecutive weeks and must also mail actual notice to all known or reasonably ascertainable creditors.

Four-month creditor deadline. Creditors have exactly four months from the date of the first published notice to file their claims. Claims not filed within this window are permanently barred. Do not distribute assets to heirs until this window has definitively closed.

Medicaid estate recovery. Notify the KDHE Estate Recovery Unit of the probate filing to compel the state to present any KanCare claims within the four-month creditor window. If a recovery notice arrives, consult an elder law attorney before responding.

April 15 of the Year Following Death

Final Kansas Form K-40. The deceased's final Kansas individual income tax return must be filed by April 15 of the year after death. If the deceased was married, the surviving spouse may elect to file jointly for the year of death. If a refund is due, Form RF-9 (Decedent Refund Claim) must accompany the K-40.

Final federal Form 1040. Same April 15 deadline as the K-40.

9 Months After the Date of Death

Federal Form 706 (if applicable). For estates with assets potentially exceeding $15 million, the federal estate tax return (Form 706) is due nine months after the date of death. An automatic six-month extension is available if requested before expiration.

Portability election deadline. Even if the estate owes no federal estate tax, an executor who wants to preserve the deceased spouse's unused federal exemption for the surviving spouse must file Form 706 to make the portability election. This deadline is also nine months after death. Miss it and the surviving spouse permanently loses the ability to use the deceased spouse's exemption — a significant loss in any estate approaching the $15 million threshold.

15th Day of the 4th Month After the Estate's Tax Year Closes

Kansas Form K-41 (Fiduciary Income Tax Return). If the estate generated taxable income during administration, the K-41 must be filed by the 15th day of the fourth month after the close of the estate's tax year. For an estate on a calendar year, this is April 15 annually for each year the estate remains open and generating income. For estates on a fiscal year, the date shifts accordingly.

After 6 Months from Date of Death

Determination of Descent. If real estate needs to be transferred but formal probate was not opened within the first six months, a Determination of Descent proceeding under K.S.A. 59-2251 becomes available. This is a court procedure that clears the title based on the will or intestate succession without requiring full probate administration. It is only available after the six-month window passes.

Final Distribution

Do not close the estate and distribute remaining assets until:

1. The four-month creditor claim period has expired
2. All authenticated debts are paid in order of statutory priority
3. All required tax returns (K-40, K-41, any Form 706) have been filed
4. Any Medicaid recovery claims have been resolved

The executor files a verified accounting with the district court and formally closes the estate.
