My spouse passed away in 2024 after an illness, we normally would file joint but he had a payout on his Retirement plan that would push my income over the limit for Marketplace insurance and income for SS. If I file single or head of household I would still be over about 10K on the Market place income before deductions as a result of a payout on part of my retirement. With only me in the household since his death do I file single or head of household to reduce as much liability as possible?
