There is no legal reason why you can't use your home address, and some tax advantages to doing so: while you'd want to check with your tax preparer, as a general rule, if you hae a home office, some modest, appropriate amount of rent, utilities, telecommunications, etc. can be deducted as a business expense.If you will, even infrequently, have clients in your home, you'd have to let your insuer know and get some additional coverage, or else risk having coverage declined if they are injured on-site.
