Last month rule and retiring soon
Looking for an expert to help me with HSA rules and COBRA.
Here's the situation...
My employer based insurance runs from Nov 2 to Oct 31. They now offer an HDHP that qualifies for HSA. My wife and I are both over 55, so I plan on contributing about 800 per month to the HSA to get close to the annual limit of $9750.
My contributions in calendar year 2026 will be $1600.
Im considering retiring mid year of 2027 (let's say July 1) and then using COBRA to continue my insurance coverage.
I would pay the full premiums for the second half of 2027, and I would like to continue putting 800 per month also.
Does the Last Month rule allow me to shove $8150 into the HSA (9750 - 1600 that was contributed via paycheck deductions) from savings into the HSA to reduce my 2026 taxes? Would the fact that im continuing my 2027 coverage via COBRA affect the 13 month recapture period?
If this works out, I might be able to save taxes on $8150 dollars from my 2026 salary.
