Tax law does occasionally change, and it can influence your most optimal financial path. For example, with the 2017 federal tax cuts capping SALT deductions at $10k, mortgage interest deduction went away for high-income earners in high-income states. The loss of a tax benefit makes home-ownership a slightly less attractive option. In California, a single person pays $10k in state income tax on an income of about $142,510. It's good to pay attention somewhat regularly, as it could impact planning. Annually, limits for 401(k)'s and IRA's are re-assessed, as well. When possible, you should take full advantage of completely filling tax-advantaged accounts (and not relying on last year's numbers).
