How to Handle Lottery-Size Money If You're Lucky

Step-by-step guide to managing a sudden windfall without losing it to taxes, bad decisions, or family drama.

  1. Stay quiet and secure the money immediately. Don't tell anyone except your spouse until you have a plan. Sign the back of the ticket and store it in a safe deposit box or home safe. Take photos of both sides. Contact the lottery office to understand your claim timeline — you typically have 180 days to 1 year depending on your state.
  2. Choose lump sum and hire professionals fast. Take the lump sum option unless you're terrible with money — the annuity payments lose to inflation and investment returns over time. Hire a fee-only fiduciary financial advisor, a CPA who handles high-net-worth clients, and an estate planning attorney within 30 days. Interview at least 3 candidates for each role.
  3. Set aside taxes immediately. Put 40-50% of your winnings in a high-yield savings account for taxes. Federal taxes will take 24% upfront plus up to 13% more at filing time. State taxes vary from 0% to 13% depending on where you live. Don't touch this money — treat it as already spent.
  4. Pay off all high-interest debt. Eliminate credit cards, personal loans, and any debt above 5% interest rates immediately. Keep your mortgage if the rate is below current investment returns. This gives you a guaranteed return equal to whatever interest you were paying.
  5. Build your safety net to 12 months. Create an emergency fund covering 12 months of expenses in a high-yield savings account earning 3.5-4.5% APY as of 2026. This is larger than the typical 3-6 months because your lifestyle costs will likely increase and you want extra buffer for your new financial complexity.
  6. Invest the rest in diversified index funds. Put remaining money in low-cost broad market index funds across U.S. stocks, international stocks, and bonds. A simple three-fund portfolio works well. The 4% rule suggests you can safely withdraw 4% annually — so $1 million invested gives you roughly $40,000 per year in sustainable income.
