Welcome to OpenStreetMap.

Rather than using amenity=office, which is deprecated and unlikely to be rendered on maps, a tag like office=accountant, office=financial_advisor, or office=tax_advisor should be used.

Adding your address would probably  also help people find you.

I have added links to the relevant documentation below, but please let me know if you need any help.
