As part of my continuing education, I attend webinars to help me keep up to date on tax changes as they occur. The IRS has relaxed the QBI deduction rules. Business owners may now file as Married Filing Separate and still receive the QBI deduction. A couple filing jointly will receive the deduction based on new limit of $321,400.00. Married filing separately will receive the deduction based on the new limit of $160,725.00. The new deduction numbers have inflation factored into the net profit amount.
