Well I assume taxes are simpler.

You don't need to know exactly who is living in each apartment. They need to know:

• Your address to know where to reach you
• Your marital status
• If you own or rent your apartment (issue is not with single family homes)
• If you have children living with you, then this is reported in your tax declaration, however the issue is not with children but other adults in the same building from my understanding
• If you are living with someone/sharing an apartment and complete separate tax declarations, then this could be an issue for the information that Serafe needs.

The simplest way to fix this would be to have apartments numbered however this would be a huge undertaking.
