There are many kinds of trusts that you could opt for to create for your beneficiaries. Each type has its own benefits to consider. For example, a credit-shelter trust helps you give your estate to your spouse tax-free while also stating who you want to receive the trust. When your spouse passes away, you can even determine who will receive the remaining principal tax-free.
Another type of trust to consider is an irrevocable life insurance trust, or ILIT. This helps remove the life insurance policy from your estate, so it's not taxed. You can then use that money to pay costs associated with the estate or give that money to beneficiaries.
