Summer is a good time to do business entertaining. Keep records of the cost, the date, the attendees, and the business purpose. Your deduction is limited to 50% of the cost.
Summer is the ideal time to create or update your estate plan as part of your overall tax-reduction efforts.
If you and your spouse work, the cost of sending your children to a summer day camp may qualify for the child care credit.
If you have an unincorporated family business, hire your children to work this summer. Their wages are deductible to your business and will be taxed in their lower tax brackets. There's no social security tax on wages paid to your children who are under age 18.
