Have a Tax Question? Ask a Tax Expert
Thank you for your question. As long as you do not file a joint tax return with him, he will have no information on you. The IRS takes your privacy very seriously and will not jeopardize your safety and tell him where you are. However, you would not be qualified to take an exemption for him unless you file a joint return. Then, he could possibly get your address but you could get around it by filing and using a PO box as a mailing address.
Please let me know if you need anything additional . If not, please rate positive.
