Do I have to pay a gift tax on receiving a gift of $300000 in the state of Massachusetts?

[bwa · Accepted solution]

You do not.  The recipient of a gift is not taxed on the gift, nor do they file a gift tax return.  The donor, because the gift was over $14,000, would need to file a gift tax return but it's unlikely they would owe a gift tax unless they previously gave gifts over $5,000,000.
