Family gift & support budget calculator
See how much you can give to family and friends from your lottery winnings while keeping your portfolio intact. Enter your after-tax prize, planned spending, and gift intentions — the calculator shows whether your plan is sustainable and flags gift tax thresholds. Use the lottery tax calculator to estimate your after-tax amount first.
How the gift tax exclusion works for lottery winners
The $19,000 annual exclusion
In 2026 you can give any one person up to $19,000 with no gift tax and no paperwork.2 There's no limit on the number of recipients — you could give $19,000 to 20 different family members and none of it is reportable or taxable.
Married gift-splitting doubles it
If you are married, you and your spouse can each give $19,000 to the same person — $38,000 combined — using "gift-splitting," even if the funds came entirely from your prize. You must file Form 709 to elect gift-splitting in any year you use it.3
Above the exclusion: lifetime exemption
Gifts above the annual exclusion reduce your lifetime estate and gift exemption, which is $15,000,000 in 2026 under the OBBBA.4 Until you've used the full $15M, gifts above $19,000/person are still not taxed — they just chip away at the exemption that protects your estate.
Direct payments bypass the limit
Payments made directly to a school for tuition or directly to a medical provider for treatment don't count against the annual exclusion at all. If you're paying a parent's medical bills or a child's college tuition, pay the institution directly rather than giving cash.5
The portfolio sustainability question
The gift tax rules tell you what's reportable. The sustainability question is separate: how does your total giving affect how long the money lasts?
Lottery winners often anchor to the jackpot number rather than the after-tax amount — and then anchor the after-tax amount rather than the sustainable withdrawal from it. The calculator models both problems: whether your combined spending (personal + gifts) is covered by investment returns, and if not, how quickly the portfolio draws down.
Lump gifts vs. ongoing support
A one-time $50,000 gift to a sibling is very different financially from a promise to pay them $50,000 per year indefinitely. The calculator models recurring annual gifts. If you're thinking about one-time gifts instead, use the investment income calculator to understand your sustainable income ceiling, then judge whether the lump gift fits within it.
Common gifting scenarios
| Prize (after-tax) | Recipients × Avg gift | Personal spending | Annual income (5.5% gross, 23.8% tax) | Outcome |
|---|---|---|---|---|
| $2,000,000 | 3 × $20,000 | $100,000 | $83,820 | Depleting (~14 yr) |
| $3,000,000 | 4 × $19,000 | $120,000 | $125,730 | Sustainable |
| $5,000,000 | 6 × $25,000 | $180,000 | $209,550 | Depleting (~23 yr) |
| $5,000,000 | 5 × $19,000 | $115,000 | $209,550 | Sustainable |
| $10,000,000 | 8 × $30,000 | $250,000 | $419,100 | Sustainable |
| $10,000,000 | 10 × $50,000 | $300,000 | $419,100 | Depleting (~22 yr) |
After-tax return = 5.5% gross × (1 − 23.8%) = 4.191%. "Sustainable" means combined spending + gifts ≤ after-tax annual returns; principal not touched. Scenarios are illustrative, not personalized advice.
Setting a family policy before the money arrives
The hardest part of gifting after a lottery win is the timing: requests arrive before you've had time to model anything. Committing to an amount — even informally — before you know what's sustainable creates pressure that's difficult to reverse.
A fee-only advisor can help you establish a written family support policy before you respond to requests: a total annual gift budget, per-person limits, criteria for loans vs. gifts, and a process for handling requests. This isn't about being ungenerous — it's about protecting your ability to remain generous for decades rather than exhausting the prize in the first few years.
See our guide on handling family requests after winning the lottery for the full framework, including scripted responses and the advisor-as-buffer approach.
Build a sustainable family support plan with a fee-only advisor
The calculator gives you the math. A fee-only advisor can help you draft a family gift policy, model gift-splitting elections, coordinate with an estate attorney on large transfers, and set a per-person annual budget that fits your long-term financial plan.
