CA tax erosion on bank interest

CD vs MYGA Calculator

Two ways to fund LTC

How to Pay for Long-Term Care

70% of 65-year-olds need LTC. California memory care runs $8,500โ€“$14,000/month and is rising 3-5%/yr. Two ways to fund it: SIS monthly payments cover the bill directly, OR a OneAmerica Asset Care policy delivers a 3-5ร— LTC pool (with a death benefit if you never need care). Plus the "stack both" case.

Creative SIS scenarios

SIS Use Cases โ€” beyond the obvious

Eight situations most CPAs miss: primary residence over ยง121 cap, sale-to-kids deferral, inherited property + MYGA stack, dental-practice exit, partnership unwind. Where SIS does work, where it doesn't.

Buyer-side reference

You're the Buyer โ€” what you sign

If you're on the buying side and the seller asked you to sign an SIS rider: every document, what it does, what it doesn't, and why it's NOT a 1031 exchange or a DST.

CRT + ILIT + GUL combo

Wealth Replacement (for CRT planners)

If your attorney structures a Charitable Remainder Trust, the heirs lose the corpus. Standard fix: an ILIT-owned guaranteed UL replaces the trust value tax-free outside the estate. The piece I handle.
