7 Retirement Planning Mistakes Long Islanders Make in Their 50s (and How to Fix Them)

By the time you hit your 50s, retirement is no longer some distant goal on the horizon. It’s close enough to feel real — which means the decisions you make now start carrying more weight. Unfortunately, many Long Islanders don’t realize that some of the biggest retirement mistakes aren’t actually made at the finish line; they’re made years earlier when you still have room to shape the outcome.

That’s why your 50s matter so much. It’s often one of the last real windows to adjust your strategy before leaving the workforce. Taxes, Social Security, healthcare, debt, and investment decisions all start to interact in ways that can either strengthen your retirement plan or leave money on the table.

The good news is that most of these gaps are completely addressable — if you get to them early.

Here are seven areas where Long Islanders in their 50s often have an opportunity to sharpen their retirement planning, and what to do about each one while you still have leverage.

Mistake 1: Underestimating NY Taxes

Many retirees assume they won’t have to worry as much about taxes once they stop collecting a paycheck. Unfortunately, tax impact is a very real thing in your golden years, especially on Long Island. New York State taxes income on a sliding scale ranging from 4% to 10.9%. That includes retirement income. Pensions, IRA withdrawals, 401(k) distributions, most of it is fair game. There’s a $20,000-per-person exemption for those over 59½, which helps, but strategic planning beyond that threshold is essential.  Layer on some of the highest property taxes in the country, and staying put on Long Island without a plan isn’t a lifestyle decision — it’s an expensive default.

The fix: Run a post-retirement tax projection now. Know what your income will look like after taxes, not just before. Strategic Roth conversions, capital gains harvesting, and timing of withdrawals can all reduce your lifetime tax burden — but only if they’re planned before you retire, not after

Mistake 2: Over-Relying on Home Equity

Your Nassau or Suffolk County home may have appreciated significantly. That’s real wealth — but it’s not a paycheck. Too many Long Island pre-retirees mentally “count” their equity as a retirement safety net, without ever deciding how, when, or whether to actually access it. Downsizing, relocating, renting, or holding all lead to very different retirement outcomes, and equity doesn’t pay your grocery bill.

The fix: If you’re counting on your house to fund retirement, have a real plan for how and when that equity becomes cash. Are you selling? Downsizing? Relocating? Timing matters, and so does the tax impact. Waiting until you’re forced to move is not a strategy.

Mistake 3: Ignoring Healthcare Cliffs

If you retire before 65, you’ve got a Medicare gap to solve. Private insurance, COBRA, or marketplace coverage all carry real costs — and they’re often higher than people expect. Healthcare is already one of Long Island’s most expensive line items, and retirement costs are highly individual and nearly impossible to predict with precision. One major health event without a plan can do serious damage to a portfolio that was otherwise right on track.

The fix: Model healthcare expenses into your retirement budget before you give notice. Know what coverage will cost, how long you’ll need it, and whether subsidies apply.

Mistake 4: Letting Portfolio Risk Drift

The investment mix that built your wealth isn’t necessarily the right mix for preserving and distributing it. As part of any solid Long Island pre-retirement plan, the conversation in your 50s shifts from accumulation to something more nuanced: enough growth to outpace inflation over 25 to 30 years and enough stability to survive a rough start. Most people don’t make this adjustment on purpose. They just don’t make it at all.

The fix: Get a real portfolio review. Not a statement check — a strategy conversation that maps out a flexible strategy that can help withstand bumpy markets.

Mistake 5: Carrying Debt Into Retirement

A mortgage, a car payment, a home equity line, high-interest credit cards — these feel manageable when the paychecks are steady. They feel very different when they’re not. High fixed expenses restrict your flexibility and could potentially put pressure on your withdrawals before you’re ready for them. For Nassau and Suffolk County residents already navigating high costs, this isn’t a small issue.

The fix: Build a debt payoff timeline now, while you still have earned income to work with. Enter retirement as light as possible.

Mistake 6: Guessing on Social Security

Claiming Social Security at the wrong time is one of the most expensive retirement mistakes people make. Even just a few years’ difference in when you claim can mean tens of thousands of dollars over your lifetime. Most people pick a date based on a hunch, a neighbor’s advice, or a vague sense that “earlier is better.” It often isn’t.

The fix: Run the actual scenarios. Your Social Security claiming strategy should be a deliberate part of your income plan, not an afterthought.

Mistake 7: DIYing Something This Complex

Your financial life in your 50s isn’t simple. You’ve got multiple accounts, a tax picture that shifts every year, a home that may be your largest asset, and decisions around Social Security, healthcare, and withdrawal sequencing that all interact with each other. Trying to manage all of that alone isn’t frugal — it’s risky. Working with an experienced Long Island financial planner who knows how to create a comprehensive strategy that aligns your investments, taxes, estate documents, and income strategy can help ensure you’re approaching retirement with a plan that’s actually built for your life, not a generic template pulled off the internet.

The fix: Bring in a professional. Work with a fiduciary financial advisor who is capable of coordinating strategies with other professionals on your team, such as your CPA and estate attorney. Comprehensive planning isn’t about having more accounts. It’s about making sure everything you have works together to support your specific goals and vision.
