Potential Tax Policy Changes in 2025
While these inflation-based adjustments are set, additional tax changes could be on the horizon. Several proposed tax policy revisions may impact businesses and individuals, and a few potential changes include:
A reduction in the corporate tax rate (currently at 21%)
The elimination of taxes on overtime pay, tips, and Social Security benefits
These proposals, if enacted, could significantly affect tax planning strategies. Staying informed and proactive is crucial. If you have any questions about how these changes may impact your business, consult with your VAAS Pro Tax Professional for guidance.
