What this means for your business
If you're running a small business in the US or Canada, these changes likely affect you in one or more of these ways:
1. Payroll adjustments — wage bases, minimum wages, and contribution limits change annually
2. Tax planning — deductions, credits, and brackets shift what you owe
3. Retirement planning — contribution limits determine how much you can save tax-advantaged
4. Compliance deadlines — some deadlines shift based on legislation
Action items
1. Update your payroll software or provider with new rates
2. Adjust employee withholding if they've submitted new W-4s
3. Review your tax plan with your CPA for new opportunities
4. Check state-level changes — many don't adopt federal changes automatically
