How business owners over 65 can plan for healthcare costs in retirement
Healthcare planning after 65 is different for business owners. Learn how Medicare choices, income, and exit plans affect retirement costs.
Retirement healthcare planning looks different for business owners than it does for traditional employees. Many owners move into Medicare without the structure of an HR department or a large employer plan, and the decisions they make about income or business transitions can directly affect their healthcare costs.
Understanding these factors before turning 65 can make the shift into Medicare much smoother. Here’s how business owners over 65 can plan for healthcare costs in retirement.
The unique challenges for business owners
Employees usually switch from a workplace health plan to Medicare with clearer instructions and deadlines. However, some business owners may have small-group coverage, private insurance, or Marketplace plans instead. These plans do not always meet Medicare’s requirements for delaying enrollment, which can lead to penalties if you assume they do.
Because of this, business owners benefit from deciding to contact a Medicare insurance agent or financial advisor who can explain how their current coverage interacts with Medicare.
How IRMAA affects your Medicare costs
Medicare premiums for Part B and Part D are tied to your income. Through what is called the Income-Related Monthly Adjustment Amount (IRMAA), higher incomes result in higher premiums. Social Security does this by looking at your Modified Adjusted Gross Income from two years prior, which means business decisions you make at age 63 or 64 can raise your costs at 65 and beyond.
This may include business distributions, capital gains, or the timing of a business sale. Planning ahead with a tax professional can help you manage your income in a way that avoids paying more for Medicare than necessary.
Understanding your Medicare enrollment requirements
Medicare enrollment is not automatic unless you receive Social Security benefits for at least 4 months before your 65th birthday month. Another complication is that not all health plans allow you to delay Medicare without a penalty. Small group plans with fewer than 20 employees, Marketplace plans, and most private individual policies usually do not qualify as “creditable coverage” for delaying enrollment in Medicare.
If you are covered under one of these when you turn 65, you typically need to enroll in Medicare during your Initial Enrollment Period to avoid penalties that are permanent. Because of this, reviewing your current coverage with a Medicare agent several months before your 65th birthday is important.
Planning for dependents who still need coverage
Many business owners provide health coverage for a spouse or dependents through their company plan. When you move to Medicare, that coverage may end for anyone who is not Medicare-eligible. In this situation, dependents often rely on COBRA, if available, or a Marketplace plan until they qualify for Medicare. Planning for their coverage in advance helps avoid gaps and unexpected expenses.
Key planning areas to address
Health Savings Accounts (HSAs) are useful for paying Medicare expenses, but you cannot continue contributing once you have Medicare. Because Medicare can be backdated for up to six months when you apply past 65, you should stop HSA contributions at least six months before applying to prevent a potential Internal Revenue Service (IRS) penalty.
You will also need to compare Medicare options. Original Medicare paired with a Medigap policy and a Part D drug plan offers one type of structure, while Medicare Advantage provides another. The right choice depends on your health needs, budget, lifestyle habits, and preferences for provider access.
Long-term care planning is also important, since Medicare does not cover ongoing custodial care. Some retirees explore long-term care insurance, while others build the cost into their financial plan.
Transitioning into retirement with confidence
Healthcare is a major part of retirement planning, and for business owners, the process comes with added steps. By taking these steps and understanding the cause and effects of these decisions, you can transition to Medicare with fewer surprises.
Starting the process early gives you more control and helps ensure that your retirement healthcare plan supports both your financial and personal well-being.
