Moving from Rhode Island to Delaware: Residency, Taxes, and What to Prove

Possibly, starting with the period beginning July 1, 2026. Rhode Island's new Non-Owner Occupied Property Tax applies to residential properties assessed above $1,000,000 that are neither your primary residence nor occupied by you more than 183 days a year. If you rent the property out for more than 183 days a year instead, it's exempt as a rental rather than as a residence. The tax is roughly $2.50 for every $500 of assessed value above the $1 million threshold, and you need to document your occupancy or rental pattern to support whichever exemption path applies.

Likely yes, if the remote arrangement is for your own convenience rather than something your employer requires. Delaware's convenience-of-the-employer rule treats income as Delaware-source in that situation, which means you may owe Delaware tax on those wages even though you never work physically in Delaware, and you'll want to confirm Pennsylvania grants a credit for the Delaware tax to avoid paying twice on the same income.

Yes. As part of the fiscal year 2027 state budget enacted in mid-2026, Rhode Island added a phased-in surtax on income above $1,000,000 that will eventually raise the effective top rate from 5.99% up to 8.99%. It makes Rhode Island's top marginal rate the second-highest in New England, behind only Massachusetts's combined 9% rate, and it changes the math for anyone deciding whether to stay a Rhode Island resident once a large capital event, like a business sale, pushes them over that threshold.

Under 30 Del. C. § 1103, you're a Delaware resident for tax purposes if you maintain a place of abode in Delaware and spend more than 183 aggregate days in the state during the tax year, regardless of where you consider yourself domiciled. This is separate from, and in addition to, being taxed as a resident because you're actually domiciled in Delaware.

Not by itself. Rhode Island's statutory residency test requires both a permanent place of abode and more than 183 aggregate days of actual presence in the state during the taxable year. An apartment visited only occasionally, well under that day count, does not trigger statutory residency even if it remains available to you year-round.

You could be, if the Rehoboth house counts as a 'place of abode' you maintain and your total time in Delaware across the year exceeds 183 days, even split across multiple visits. Delaware's statutory-residency test doesn't require the home to be your primary residence, just a place of abode you keep, combined with the day count.

Not exactly, and it's less forgiving in one specific way: Rhode Island exempts Social Security only below certain federal AGI thresholds, and its separate pension exclusion, up to roughly $15,000 for taxpayers 65 and older, disappears entirely once income crosses that same threshold, rather than phasing out gradually the way some neighboring states structure their exemptions. Retirees near that income line should model the cliff carefully rather than assume a smooth reduction.

No. Delaware repealed its estate tax effective January 1, 2018, and has no separate inheritance tax. Only the federal estate tax can apply to a Delaware domiciliary's estate above the federal exemption.

It's considerably less forgiving on a dollar basis. Rhode Island's exemption, indexed annually for inflation, exempted the first $1,774,583 of a net taxable estate for decedents dying in 2024, the second-lowest exemption threshold in the country behind only Oregon's flat $1,000,000. Massachusetts's exemption is higher at $2,000,000, and Connecticut's matches the multi-million-dollar federal exemption, so a Rhode Island estate can owe state estate tax at a much lower net worth than an otherwise-similar estate in a neighboring state.

Social Security is fully exempt from Delaware tax. Delaware also allows a pension and retirement income exclusion of up to $12,500 per person for taxpayers 60 or older, covering pensions, 401(k), and IRA withdrawals; amounts above that exclusion are taxed at Delaware's ordinary rates, up to 6.6%.

There's no public record of Rhode Island running an audit program on the scale of New York's or Connecticut's, and no widely reported published case law exists comparable to those states' court decisions. That said, the state just created two new, direct financial incentives, the millionaire's surtax and the Non-Owner Occupied Property Tax, both effective in 2026, that give the Division of Taxation fresh reasons to scrutinize high earners and second-home owners more closely than it has historically needed to.

You may qualify for Delaware's foreign-residence exception: if within any consecutive 18-month period you're present in a foreign country at least 495 days, present in Delaware no more than 45 days, don't maintain a Delaware abode where your family stays more than 45 days, and aren't a federal government or military employee, Delaware treats you as a nonresident for that period despite your domicile.
