When a loved one passes away in California, the estate or trust they leave behind may have ongoing tax filing obligations — both federal and state. Executors, trustees, and beneficiaries often find themselves navigating unfamiliar territory. Knowing how to find a qualified tax professional for estate and trust tax matters can prevent costly errors and delays.
What Filings May Be Required
- Federal estate tax return (Form 706): Required for estates above the federal estate tax exemption. The IRS sets this threshold and adjusts it periodically. For estates below the threshold, a Form 706 is not required — but may still be worth filing in some situations.
- Federal income tax return for the estate or trust (Form 1041): A domestic estate must file Form 1041 if its gross income for the tax year is $600 or more, or if a beneficiary is a nonresident alien. A domestic trust taxable under section 641 must file if it has any taxable income for the tax year, gross income of $600 or more, or a nonresident alien beneficiary.
- California Fiduciary Income Tax Return (Form 541): Form 541 is generally needed only where the estate or trust has a California connection (a California fiduciary, a California noncontingent beneficiary, or California-source income) and meets one of the FTB filing thresholds for estates or trusts (gross income, net income, or an alternative minimum tax liability). Check the current-year Form 541 booklet.
- Final personal return for the decedent: The executor must file the decedent’s final Form 1040 and California Form 540 for the year of death.
What to Look for in a Professional
Estate and trust taxation is a specialty. Not every CPA or EA has hands-on experience with Form 706 or fiduciary income tax returns. When searching for help, prioritize professionals who can demonstrate:
- Experience preparing Form 1041 and California Form 541
- Familiarity with fiduciary duties and the tax responsibilities of executors and trustees
- Knowledge of California’s income taxation of trusts, which differs from federal rules in important ways
- Experience coordinating with estate attorneys on asset valuations and distributions
Questions to Ask
- How many estate or trust income tax returns do you prepare annually?
- Do you coordinate with probate or estate planning attorneys?
- Are you familiar with California’s throwback rule for accumulated trust income?
