What you should do
1. Plan for the temporary nature of child tax credits — they'll be less generous after 2028
2. Max out retirement contributions while the higher limits are available
3. Don't worry about the standard deduction — it's permanent and will grow with inflation
4. Review your situation in late 2028 to prepare for 2029 child tax credit changes
Key takeaway: About 75% of the 2026 tax law benefits are permanent, including the higher standard deduction and retirement account improvements. Only the enhanced child tax credit expires after 2028, reverting from $3,000/$2,500 back to $2,000 per child.
