Location always matters. Consider a married couple, both aged 65, retiring with $1.8 million in combined IRAs and brokerage assets. They plan to draw around $108,000 a year of ordinary income, most of it from traditional IRA withdrawals, and they intend to stay in New Jersey. Their online retirement calculator says they are fine but it might miss their actual state tax bill.
This is one of the more common blind spots for affluent Northeast retirees. National retirement calculators almost universally model federal taxes plus a flat state rate. They do not consider the New Jersey pension exclusion cliff, which is where this couple gets clipped for roughly an extra $11,400 per year (depending on their income mix and deductions).
New Jersey offers a retirement income exclusion that can shield up to roughly $100,000 of pension and IRA income for married couples filing jointly, but only if total income stays under $150,000. Cross that line by even a dollar, and the benefit phases out sharply. With $108,000 of planned retirement income, two Social Security checks, a little dividend income from the taxable account, and a Roth conversion, and the couple is already brushing the threshold.
For context, New Jersey is already an expensive place to retire before taxes. The state’s cost-of-living index sits at 108.8, the fourth highest in the nation, and real income per capita is $77,978, eroded meaningfully by housing, property tax, and goods prices.
Total Income, Not Withdrawal Size, Drives the Bill
The number that matters is total income: Is it $149,000 or $151,000? At the federal level, this couple is comfortably in the 12% bracket and bumping the 22% bracket. The 2026 married filing jointly (MFJ) standard deduction is $32,200, and the 22% bracket starts at $100,800 of taxable income. So their federal bill is manageable.
The New Jersey bill is where rounding errors become real money. A $5,000 mistake in withdrawal sizing, an unexpected capital gain distribution in December, or a Roth conversion done in the wrong year can knock the exclusion out entirely and convert what looked like a tax-advantaged retirement into a fully taxed one at the state level.
Two Strategies That Could Move the Number
The first path: Engineer total income to stay under the $150,000 line. That means sequencing withdrawals deliberately, drawing from the taxable brokerage account first (where only the gain is taxed, not the principal), letting the IRA grow another year or two, and timing Social Security claims to control the year a benefit begins. Capital gains harvesting and tax-loss harvesting in the taxable account also help keep adjusted gross income compressed.
The second path: Do aggressive Roth conversions in the gap years between retirement at 65 and RMDs at 73. The reasoning is direct. As Suze Orman has put it, “Do not convert it all at once to a Roth because you will owe ordinary income taxes on it in the year that you convert. So do it little by little.” Converting in $30,000 to $40,000 slices keeps the federal bracket tame and shrinks the future RMD that would otherwise blow through the New Jersey threshold every year for the rest of their lives.
And a third option some readers will research: Move. Pennsylvania does not tax most retirement income, and Delaware applies relatively low rates. Both share a border with New Jersey, and both deserve a serious look for a couple that would consider moving.
What to Evaluate First
Run the actual New Jersey return at three income levels: $145,000, $150,000, and $160,000 of total income. The common mistake is treating $108,000 of IRA withdrawals as the whole picture. Social Security, brokerage dividends, and any part-time income all count toward that $150,000 line, and the cliff does not care which bucket the dollar came from.
