Accountants are uniquely positioned to optimize their own tax situations, but many overlook the basics. If you hold a CPA license, continuing education costs may be deductible as a business expense for self-employed accountants.

Self-employed accountants should consider the Qualified Business Income (QBI) deduction, which can reduce taxable income by up to 20% of qualified business income.
