Form 1041 -
Estate & Trust

Technical scope we cover

• Distributable net income (DNI) calculation and income distribution deduction
• Fiscal year election assessment, first-year estates only
• Simple vs. complex trust classification and its implications per year
• Grantor trust reporting requirements
• 65-day rule elections for distributions treated as made in the prior year
• Passive activity rules for trust-held investments and PTPs
• Net investment income tax (NIIT) at the trust level: trusts reach the 3.8% NIIT threshold at just $16,000 of income in 2026
• Deduction allocation between income and corpus
• Final year return: excess deductions on termination allocated to beneficiaries by character (above-the-line Sec. 67(e) administration costs, NOL carryovers, and capital loss carryovers each pass through separately)
• K-1 preparation for all beneficiaries, delivered through the portal

Multi-year estate engagements

Estates that remain open for multiple years require coordination across filings: tracking carryforward items, monitoring income against deductions, and advising on distribution timing to shift income to beneficiaries at more favorable rates. We handle multi-year engagements and can take over from a prior preparer mid-administration.

Coordinated with the beneficiary side

We can prepare beneficiary returns alongside the 1041, ensuring K-1s and individual returns are consistent. This is particularly valuable when beneficiaries are receiving complex pass-through income: PTPs, real estate, or S corporation income from trust-held assets.

What we need to open a matter

• Estate or trust EIN
• Trust document or will, and Letters Testamentary or Trust certification
• All income statements for the period: 1099s, brokerage statements, K-1s received
• Distribution records and beneficiary information
• Deductible expenses for the period
• Prior year Form 1041 if taking over mid-administration
