529 Plan Guide: Tax Benefits, Contribution Limits, and State Rules

529 plans offer tax benefits that can help save money when paying for college. However, the value of these tax deductions varies based on factors like how much you contribute, how long you contribute, and the state you live in.
What is a 529 Plan?
A 529 plan is a savings plan designed to help pay for college. Family members and friends can contribute. The main advantage is that withdrawals are usually not taxed federally, and often not by the state either. This means your savings can grow without being taxed.
The earlier you start saving, the more you benefit.
How Much You Contribute Matters
The amount you contribute can reduce your state taxable income. For example, in a state with a 5% tax rate, a $1,000 deduction saves you $50. Not all states offer this deduction, and it doesn’t apply to federal taxes. Even though contributions are made with after-tax income, some states let you deduct them from your state taxes, which can increase your savings. Plus, the earnings in the plan aren’t taxed federally.
Annual Contribution Limits
State Limits:
States set maximum annual deductions. To get the most benefit, spread contributions over many years rather than making large, lump-sum payments.
Federal Limits:
You can give up to $18,000 per year without triggering a gift tax. You can also make a larger one-time contribution by spreading it over several years, known as “superfunding.” Most people won’t exceed the lifetime limit of $13.61 million.
Your State of Residence Matters
Tax rules vary by state. Some states don’t offer a deduction at all, while others allow up to $18,000 per year. If your state’s limit is low, start contributing early and space out your contributions to maximize the benefit.
Don’t Forget About Interest
Starting early means your savings have more time to grow. The money you save through deductions will also grow each year, increasing your total savings. Plus, these earnings aren’t taxed federally, so you save even more.
