The other neat thing about ETFs is that there are so many similar, you can effectively use them for TLH to help offset future gains.
I'm not an IRS agent and have no idea what they mean by substantially similar. You might want to talk to your tax accountant.
They actually use the word 'identical' instead of 'similar', if that matters. It seems to be a grey area with ETFs, and I'm not a financial advisor, so won't make any further claims.

Absolutely agreed. You can also just let a reputable robo do it for you if you don't have the time or energy for it, there are multiple. It is what I ended up doing. It's modest but every bit helps.
