How to Compare U.S. 529 Plans Without Chasing a 'Best' State

A 529 plan is a tax-advantaged savings account designed to help families save for future education costs. Named after Section 529 of the Internal Revenue Code, these plans are sponsored by individual states and administered by financial institutions. 529 plans offer significant tax benefits that make them one of the most popular education savings vehicles in the United States.

The primary tax advantage of a 529 plan is that earnings grow federally tax-deferred, and withdrawals used for qualified education expenses are completely tax-free at the federal level. This means that you never pay capital gains tax or income tax on the investment growth in your 529 plan, as long as the money is used for qualified education expenses such as tuition, fees, room and board, books, and computers. Many states also offer state tax deductions or credits for contributions to a 529 plan.

529 plans have two main types: college savings plans and prepaid tuition plans. College savings plans are investment accounts where contributions are invested in mutual fund-like options. The account value fluctuates with the market. Prepaid tuition plans allow you to lock in today's tuition rates for use at public colleges and universities in a specific state. Prepaid plans have become less popular as tuition costs have risen faster than investment returns.

State Tax Benefits vs. Plan Quality

A common misconception about 529 plans is that you must open an account in your home state to maximize benefits. In reality, you can open a 529 plan in any state, regardless of where you live. However, the tax benefits you receive depend on the interaction between your state of residence and the plan you choose.

Many states offer a state income tax deduction or credit for contributions to any 529 plan, while other states only offer the deduction for contributions to their own state's plan. Some states (including California, Delaware, Hawaii, Kentucky, Massachusetts, Minnesota, Montana, New Jersey, North Carolina, and South Carolina) offer no state income tax benefit for 529 contributions regardless of which state's plan you choose.

If your state offers a tax deduction for contributions to its own 529 plan, that deduction may provide more benefit than the superior investment options or lower fees of an out-of-state plan. For example, if you live in New York and pay 8.82% state income tax, a $10,000 contribution to the New York 529 plan saves you $882 in state taxes. This tax savings may outweigh the advantages of an out-of-state plan with slightly lower fees.

| State | Tax Benefit for In-State Plan | Tax Benefit for Out-of-State Plan | Notable Plans |

|---|---|---|---|

| New York | Up to $10,000 deduction (joint filers) | No deduction | NY Direct Plans (low-fee) |

| California | No deduction | No deduction | No home-state advantage |

| Illinois | Up to $10,000 deduction | No deduction | Illinois 529 (Bright Start) |

| Texas | No state income tax | N/A | No home-state advantage |

Investment Options and Fees

529 plan investment options vary significantly between states. Most plans offer age-based portfolios that automatically adjust the asset allocation as the beneficiary gets older, becoming more conservative as the target date approaches. These target-date portfolios are popular because they require no active management from the account owner.

Most plans also offer static portfolios that allow you to select a specific asset allocation. Static options typically include conservative portfolios (high bond allocation), moderate portfolios (balanced stock and bond allocation), and aggressive portfolios (high stock allocation). Some plans also offer individual fund options, including index funds and actively managed funds.

Fees are an important consideration when comparing 529 plans. Plans charge administrative fees (often 0.10% to 0.50% annually) and investment management fees (expense ratios for the underlying funds, typically 0.10% to 1.00%). Low-cost plans with index fund options can have total annual fees below 0.20%, while plans with actively managed funds or high administrative fees can exceed 1.00% annually. Over 18 years of saving, a 0.80% difference in annual fees can reduce the final account value by tens of thousands of dollars.

When to Get a New EIN

While most changes to your business do not require a new EIN, certain events trigger the need for a new EIN. The IRS provides specific guidance on when a new EIN is required and when you can continue using your existing EIN.

You need a new EIN if your business structure changes — for example, if a sole proprietorship incorporates, if a partnership takes on new partners, or if a corporation converts to a partnership or LLC. You need a new EIN if you create a new business entity through merger or division. You need a new EIN if you establish a new trust or pension plan. You need a new EIN if you are a government entity that changes its ownership structure.

You do NOT need a new EIN if you change the name of your business (as long as you notify the IRS), if you move your business to a different location, if you add or remove owners in a corporation (unless it results in a new partnership), if you reorganize a corporation (such as a corporate merger that results in a new corporation), or if you elect to change your business classification (such as from a sole proprietorship to an LLC that is taxed as a sole proprietorship).

When in doubt, consult the IRS guidelines or call the Business and Specialty Tax Line at 800-829-4933. The IRS provides a comprehensive guide titled "Do You Need a New EIN?" that outlines every situation that requires a new EIN.
