Inheritance taxes.

What is the name of your state (only U.S. law)?
The property is in california, the beneficiary is in Florida.

Are there inheritance taxes on property provided by an A-B trust when both owners of the trust have passed and left property to a beneficiary.?
How soon can the beneficiary sell the property after the transfer of title has been made to the beneficiary?
What is the new tax basis for the property?
Thank you.

There's no such thing as a federal inheritance tax. There are estate taxes.
Provided that the person died recently, there's no estate nor inheritance tax in California.

What year did each person in the trust die?
How was the property titled in the trust.

Both affect the tax issues on the estate and the basis of the resulting property.

You can sell it as soon as it's deeded to you.

As noted, the beneficiary lives in Florida. Therefore the question of Inheritance would be for that state.
The property is titled as part of the A-B trust.

It is my understanding that the tax basis becomes the value of the property at the time of death of the trust holders? (after fair market valule).?

The person(s) has not died, the questions are "what if" and in preparation to.

Thanks for the comments. All help is appreciated.

It matters exactly how the property was titled and when the parties die.

Florida has no inheritance tax either. Estate tax doesn't apply there because it matters not where the beneficiaries live but the residence of the deceased.

The basis step-up, and to what extent, again depends on when they die. The rules on all this stuff changes pretty much from year to year. You no longer get a guaranteed 100% step up.

If you're running what-ifs, I recommend you go to an estate planner to figure this out if we're talking any significant amount of equity here.
