The full breakdown of how I've lowered my tax bill over the last decade without doing anything complicated.

Tax-advantaged contributions: my 401k contribution at the 22% marginal rate saves approximately $5,060/year in current taxes on $23,000 contributed. My HSA saves approximately $930/year. Traditional IRA (when eligible) saved an additional $1,540.

Mortgage interest deduction: only matters if I itemize, which I currently don't — the standard deduction is higher for my situation.

Long-term capital gains rate: by holding index funds for over one year before any sales, gains are taxed at 15% rather than ordinary income rates (22% in my bracket). This matters for my taxable brokerage account.

Tax-loss harvesting: I've offset approximately $6,000 in capital gains over three years through strategic loss realization. Saved approximately $900 in taxes.

The cumulative tax savings from these strategies is roughly $7,000-8,000/year. Over a decade: $70,000+. None of it required complex planning or a tax attorney — just understanding the available tools.
