Formula

Tax = max(0, gift − exclusion) × assumed tax rate

Recipient net = gift − tax × (1 − outside-payment share).

What the result means

The main result is the recipient's modeled net transfer after any portion of estimated tax withheld from the gift.

This is a planning estimate, not tax, legal, or investment advice. Actual treatment depends on jurisdiction, trust terms, holding periods, and individual circumstances.

Example calculation

For a $500,000 gift, $18,000 exclusion, 30% assumed rate, and 100% paid outside the gift, estimated tax is $144,600. The recipient receives $500,000 and donor cash outlay is $644,600.

Tips for better results

  • Confirm who is legally responsible for tax before using the scenario.
  • Enter a current, situation-specific exclusion rather than relying on a default.
  • Compare 0% and 100% outside-payment cases.
  • Keep valuation discounts out unless independently supported.

Frequently asked questions

Does this calculator determine my legal gift-tax rate?

No. It applies the rate and exclusion you enter for scenario planning.

What does tax paid outside the gift mean?

It means the donor uses separate cash to pay the modeled tax instead of reducing the recipient's transfer.

Can the taxable gift be negative?

No. The calculator floors the modeled taxable amount at zero.

Why can donor outlay exceed the planned gift?

When tax is paid separately, that payment is added to the donor's cash outlay.

Does this account for lifetime exemption usage?

Only if you reflect it in the available-exclusion input; the calculator does not track a legal exemption ledger.
