The IRS is sharpening its focus on trusts at a time when affluent households are already dealing with a higher 2026 federal estate-tax exemption, new filing details, and a more complicated reporting landscape. While the agency has not announced a broad new “trust crackdown,” recent IRS guidance and proposed rules show that trusts remain a high-priority area for compliance, especially where estate, gift, and charitable reporting overlap.
That matters because trusts are central to inheritance planning. They can help families control distributions, manage taxes and protect assets — but the IRS has repeatedly signaled that it will scrutinize structures that appear to push beyond the rules. As a result, attorneys and advisers say the practical question for families is less about whether to use trusts and more about how carefully those trusts are documented, reported and administered.
According to the IRS’s estate-and-gift tax guidance, the basic exclusion amount for decedents dying in 2026 is $15 million. That higher threshold reduces the number of estates facing federal estate tax, but it does not eliminate reporting risk. The agency still requires detailed filings for larger estates, and assets held in trusts can be part of the gross estate depending on the structure.
Why the IRS is paying closer attention
The IRS’s latest guidance and related Federal Register notices show two major pressure points. First, the agency updated estate-and-gift tax rules to reflect the higher 2026 exemption and continued modernization of filing systems, including electronic filing for gift-tax returns. Second, Treasury and the IRS proposed changes in August 2026 that would eliminate a reporting requirement for certain trusts whose charitable deductions arise solely from pass-through entity contributions and would clarify that split-interest trusts file Form 5227 rather than Form 1041-A.
The reporting proposal may sound technical, but it underscores a larger point: the IRS is trying to distinguish routine trust filings from transactions that warrant closer review. In practice, that means more attention to whether a trust’s tax treatment matches its legal form, whether charitable deductions are properly sourced, and whether the right return is being filed.
That scrutiny is not limited to paperwork. The IRS also continues to challenge high-dollar estate-planning arrangements in court, including structures involving family entities, gifts and valuation disputes. In a recent Reuters report, tax enforcement data showed the IRS’s overall enforcement activity weakened after staffing cuts, but experts warned that high-end compliance remains an area where the agency still has an incentive to focus its limited resources. That suggests trust and estate cases may remain attractive targets because they can involve large amounts and complex legal questions.
What this means for families, executors and advisers
For those handling inheritance planning, the key message is that trusts are still useful, but they are not informal containers for assets. The IRS reminds taxpayers that estate tax applies to the transfer of property at death and that includible property may include cash, securities, real estate, insurance, annuities, business interests and trusts.
Families using irrevocable trusts, GRATs, QTIP arrangements or split-interest trusts should expect advisers to review:
- whether the trust is properly drafted for its intended tax purpose,
- whether annual filings are complete and on time,
- whether distributions or substitutions could trigger gift-tax issues,
- and whether documentation supports the planning rationale.
The IRS also notes that estate tax closing letters are no longer automatic and that account transcripts can be used in lieu of a closing letter for many estates. For executors, that means administrative follow-through remains important even after an estate return is filed.
For wealthy households, the broader backdrop is the coming transfer of assets from older generations to heirs. That keeps trust planning in demand, but it also raises the cost of mistakes. A trust that was created to minimize tax can become a source of IRS correspondence if the filing, valuation, or beneficiary reporting is off.
The safest takeaway is straightforward: confirm the trust’s tax posture before filing, not after the IRS asks questions.
Background worth watching
The IRS’s 2026 exemption increase to $15 million is temporary policy under current law and could still change in future legislation. Meanwhile, the August 2026 proposed trust-reporting rules are not final, but they are a useful signal of where Treasury believes the current regulations are unclear. If finalized, they could simplify some filings while clarifying that split-interest trusts should not be treated as ordinary Form 1041-A filers.
