It will work for at least another year (through 12/31/17), if you sign up this year (repealing the law will not cancel or change an already-existing insurance contract). But the enrollment deadline's coming up.
Call your senator and representative and tell them not to repeal Obamacare. It is an absolute godsend for the self-employed, entrepreneurs just starting out, people who FIRE, and more. It has truly been a game-changer for the self-employed and for startup companies, just to name two.
Late last year I transitioned from a corporate job to self-employment, and get this: the insurance I had through my former employer, which I could have continued through COBRA, would have cost over $1400/mo for my family--and it was HIGH DEDUCTIBLE insurance, so every garden-variety doctor's visit cost about $100, or $150+ for specialists! The high-deductible plan made sense at the employee price, but not once I left the firm. I found NORMAL insurance (non-high deductible) with which doctor's visits cost $10 (generalist) or $60 (specialist), all our doctors are covered, and at right around $950/mo for the whole family, it saves us almost $500/mo compared to the alternative. Thanks, Obama! ;)
