In Sag Harbor
Trust and estate tax for Sag Harbor
In an estate, the step-up against that gain is the largest single tax event, and the valuation has to be defensible rather than convenient.
Where the property is sold during the administration, the Peconic Bay transfer tax applies to the transfer, with a $400,000 allowance on improved residential property that disappears entirely above $2,000,000 of consideration.

Local tax
The tightest rental rules out here
Of the five East End areas we cover, Sag Harbor is the most restrictive on renting. Seasonal rentals require a minimum of 30 consecutive days. Two week rentals are permitted no more than twice in a calendar year. No permit is issued at all for a non owner occupied short term rental property. Penalties run up to $1,000 per day of violation.
That matters before you buy, not after. A rental plan that works in the Town of East Hampton may be simply unavailable a mile away inside the village.
The Peconic Bay transfer tax applies at 2.5%, made up of the 2% preservation fund and the 0.5% community housing fund added in April 2023. Both towns the village sits in adopted the housing fund, so the rate is the same either side of the town line. The allowance is $400,000 on improved residential property, but only where consideration is $2,000,000 or less. Above that there is no allowance and the full 2.5% applies from the first dollar. Because the village spans two towns, confirm the allowance treatment for a specific parcel with the Suffolk County Clerk.
For the marine businesses: vessel depreciation, dockage, fuel, the capitalize against repair line on engines, and a revenue curve concentrated into a few months. For the cultural organizations: Form 990. Suffolk County is MCTMT Zone 2 at 0.34%, with the self employment threshold rising to $150,000 for 2026.
How it works
How trusts and estates runs
Four stages. Most of the value sits in the first two, before anything is filed.
Fix the dates
Date of death, the fiscal year choice available to the estate, and what each one triggers.
Inventory and value
Assets, basis and the valuations every later return will rest on.
File in the right order
The final 1040, then the 1041, then the 706 or 709 where they apply.
Account, then close
Fiduciary accounting and K-1s, so the administration can actually be closed out.
Questions
Frequently asked questions
Can I rent my Sag Harbor house for a week in August?
Not as a seasonal rental. The village requires a minimum of 30 consecutive days for seasonal lettings, and two week rentals are capped at twice a year. If the property is not owner occupied, no short term rental permit is issued at all. Check the specific address before committing to anything.
Which town am I in?
Either Southampton or East Hampton, depending on where in the village the parcel sits, and it changes which town level rules apply even though the village rules are the same throughout. It is worth establishing before a purchase rather than after.
Do you work with the boatyards and marine businesses?
Yes. The recurring issues are depreciation on vessels and equipment, the treatment of major engine and gear work, and planning estimated payments around a season rather than a calendar.
Does an estate always need to file?
Not always. Whether a Form 1041 is required depends on the income the estate generates and whether there is a nonresident alien beneficiary. We would rather check than assume, because the penalty for a missed fiduciary return compounds.
I am the executor and I have never done this. Where do I start?
With an inventory and the date of death values, because almost everything else depends on them. We work alongside the estate attorney rather than replacing them.
Do you prepare gift tax returns?
Yes. Form 709 is often worth filing even when no tax is due, because it starts the clock and documents the valuation position.
