Does this affect my own declaration of taxes?

No, you still need to declare your own tax declaration in the normal way.

In terms of your own tax situation, you continue to manage your own tax affairs as before. We are unable to give tax advice, but would advise that every host should ensure they are managing their own tax affairs effectively to reduce any tax liability they may have. So for example you personally may only have a requirement to declare income over a certain threshold to your tax office owing to your personal circumstance. Or you may be eligible to avail of specific Government tax relief incentives, such as a Rent a Room Scheme, where hosting income up to a certain threshold may be tax free.
