Welcome to the tax practice of Joan Lizbeth Mashburn, CPA. I provide professional individual tax preparation and planning services to individuals in Northern Virginia and throughout the DC region from my office in Arlington, VA. I offer personalized attention throughout the year. 

I am ready to help you with prior year tax issues as well as 2018 year-end tax planning. This includes adjusting for the Qualified Business Income Deduction (QBI); the QBI is a new deduction that significantly affects taxpayers with their own businesses, allowing some to be taxed on only 80% of their business income. I have many clients who are self-emplyed, and am experienced at working with them on home office deductions, estimated tax payments, SEP IRAs, and other common issues. 

I am proud to be the trusted advisor for my clients. I have a group of skilled colleagues I work with, who help in areas outside of my focus.  

Thank you for visiting, and please contact my office if you are looking for friendly, professional tax help. 

Existing clients can securely send documents to the office using the Send Documents link to the right. New clients, please call the office or use the Contact link at the top right of every page.
