Yeah, I know I'm a beneficiary of my mum's will, but I don't know how much I'll inherit. So do I have an interest in a foreign estate now, or when the estate is all placed in probate or only after it comes out of probate and I put my inheritance in a UK financial account?
What about this reasoning.
1) I don't know the value of my mum's estate. The 8938 instructions say
Value of an interest in a foreign estate, foreign pension plan, and foreign deferred compensation plan. If you do not know or have reason to know based on readily accessible information the fair market value of your interest in a foreign estate, foreign pension plan, or foreign deferred compensation plan during the tax year, the value to be included in determining the total value of your specified foreign financial assets during the tax year is the fair market value, determined as of the last day of the tax year, of the currency and other property distributed during the tax year to you. If you received no distributions during the tax year and do not know or have reason to know based on readily accessible information the fair market value of your interest, use a value of zero for the interest.
I have no other SFFAs so while my mum is alive I receive no distributions and hence zero value and FBAR and 8938 are not required.
2) When the estate goes into probate the critical thing then seems to be whether I know the value of the estate and whether I have been deemed to receive the distribution prior to it coming out of probate.
I've seen people recommend 8939 and FBAR while the estate is in probate, but is that a prophylactic recommendation rather than one based on the application of the tax code and probate law? The reasoning in 1) seems to be equally valid for 2). Once the money is out of probate whether 3250, 8938 or FBAR are required will depend on where you put the money and the size of the inheritance.
