Reserve for Taxes Before Final Distribution

Beneficiaries want everything now. The IRS doesn’t care what beneficiaries want. A trustee who distributes every dollar before tax obligations are settled can end up paying the difference personally, and that’s not a hypothetical: it’s one of the most common ways trustees get burned. The fix is a reserve, held back deliberately, sized to a real estimate of what’s still owed, not left over by accident.

Why trustees hold back funds

A trust is a taxpayer in its own right while assets sit inside it, and the person who created the trust was a taxpayer up until the date of death. Both of those tax obligations have to be resolved before a trustee can safely say the trust’s business is finished. Trustees who distribute first and figure out taxes later are gambling with money that may no longer be theirs to give back.

Under IRC section 6901 and related California provisions, a trustee or executor who distributes assets and leaves unpaid taxes can be held personally liable for those taxes, up to the value of the assets distributed. This isn’t a rare technicality. It’s the reason experienced trustees hold back a reserve as a matter of course, not just when something seems off.

What taxes to account for

The decedent’s final income tax return

A final federal and California income tax return covers income earned by the person who died, from January 1 of the year of death through the date of death. This is due the same as any other year’s return, and it’s easy to overlook amid everything else happening right after a death.

The trust’s own income tax returns

While assets remain in the trust, generating interest, dividends, rental income, or capital gains, the trust files its own returns: federal Form 1041 and the corresponding California Form 541. Depending on how the trust is structured, this may continue for more than one tax year if administration takes a while.

Federal estate tax, if applicable

Most estates fall well under the federal estate tax exemption ($15 million per person as of 2026, $30 million for a married couple, adjusted annually), so this doesn’t apply to most California trusts. But for larger estates, a federal estate tax return (Form 706) may be required, and the tax has to be paid before the IRS will fully release its claim on estate assets.

Property tax reassessment

California property tax rules changed significantly for anyone inheriting a home after Proposition 19 took effect in 2021. A child inheriting a parent’s home generally only keeps the parent’s lower assessed value if the child moves in as their primary residence within one year, and even then, a partial reassessment can apply if the home’s value exceeds the parent’s assessed value by more than $1,044,586. Reassessment can generate a real, unexpected tax bill that hits after distribution if the trustee didn’t plan for it. See our page on Prop 19 implications when selling inherited property for how this plays out when a sale, rather than keeping the home, is the plan.

Capital gains and the stepped-up basis

Assets in the trust generally get a stepped-up basis to fair market value as of the date of death under IRC section 1014, which usually reduces capital gains exposure for beneficiaries who inherit and later sell. But between the date of death and the date of distribution, any further appreciation, or any sale by the trustee before distribution, can generate a taxable gain the trust has to report.

How long to wait

There’s no fixed statutory number for a trustee to hold funds pending tax exposure, which is exactly why trustees have to use judgment rather than a formula. A few benchmarks matter here.

The IRS generally has three years from the filing date to audit a return, extended to six years if income was substantially understated, and unlimited if a return wasn’t filed or fraud is involved. Waiting three full years before distributing every last dollar isn’t realistic for most families, but it explains why a reserve, not full distribution, is the right tool: hold back enough to cover a plausible tax bill, distribute the rest, and release the reserve once returns are filed and any audit window of real concern has passed.

Requesting a prompt assessment under IRC section 6501(d) can shorten the IRS’s audit window on the final income tax return to 18 months, giving the trustee a faster, more certain closing point.

An IRS closing letter or transcript confirmation that a filed estate tax return has been accepted is the clearest signal that estate tax exposure is resolved, for estates large enough to require one.

Sizing the reserve for a typical estate

For most California trusts, without a business interest or a federal estate tax filing requirement, the reserve is really about the trust’s own income tax return and any capital gains from a late sale of an asset. A trustee working with an accountant can usually get a reasonably tight estimate: expected tax on income earned since death, plus expected tax on any gain if the trustee sold anything above its stepped-up basis, plus a modest cushion, often 10 to 20 percent of the estimate, for the unexpected. That’s a very different number than “hold back a third of everything just in case,” which is both more than most estates need and still not tailored to the actual risk.

What happens to the reserve once it’s released

When the reserve period ends and no audit or unpaid liability has surfaced, the trustee distributes the reserve the same way the rest of the trust was distributed, following the trust’s terms for shares among beneficiaries, with its own receipt and release from each beneficiary. This final release should specifically reference the reserve and confirm the beneficiary understands it was held back for tax purposes and is now being distributed because that purpose has been satisfied. Skipping this documentation step on the reserve specifically, after being careful about it on the earlier distributions, is a common late-stage lapse.

A practical approach

Pay known debts and file all required returns first. Estimate a reasonable reserve, often the trustee’s best estimate of remaining tax liability plus a cushion, and hold that back. Distribute the rest. Once returns are processed and no audit or assessment has come in within a reasonable window, distribute the reserve. Document the reasoning behind the reserve amount in the trust accounting so beneficiaries understand why funds were held rather than distributed immediately, and see our page on trustee liability after distribution for what happens if this step gets skipped.

Reserving too much for too long can also draw complaints, and beneficiaries can petition the court to compel distribution of funds held without good reason. The goal isn’t holding back indefinitely. It’s holding back long enough to know the number is real.

The honest caveat

Sizing a reserve is judgment, not math. Too small and the trustee is personally exposed; too large and beneficiaries have a legitimate complaint. The trustee’s accountant, not a general rule of thumb, should be driving the actual number, especially where a business interest, rental property, or larger estate is involved.

Frequently asked questions

Why do trustees hold back a reserve before final distribution?

Because a trustee who distributes assets and leaves unpaid taxes can be held personally liable for those taxes under IRC section 6901 and related California provisions, up to the value of the assets distributed.

Which taxes does a trustee need to account for before distributing?

The decedent’s final personal income tax return, the trust’s own fiduciary income tax returns, federal estate tax if the estate is large enough, potential Prop 19 property tax reassessment, and any capital gains between the date of death and distribution.

How long should a trustee wait before distributing the reserve?

There’s no fixed number. The IRS generally has three years from filing to audit a return, six if income was substantially understated. Requesting a prompt assessment under IRC section 6501(d) can shorten the window on the final income tax return to 18 months.

Can a beneficiary force a trustee to release a reserve early?

Yes. Beneficiaries can petition the court to compel distribution of funds held without good reason. The goal isn’t holding back indefinitely; it’s holding back long enough that the reserve reflects a real, documented estimate.
