Frequently asked questions about management and procedures
Can I do all the procedures online with you?
Yes, we manage many procedures 100% online, including certificates, income or submission of documents. If you need to come, we also assist you in the office.
What is the difference between an agency and an advisor?
The agency focuses on procedures and documents before public bodies. An advisor may have a more strategic or fiscal focus. At Sellarès we combine both profiles according to your case.
Can I order your income tax return if I have several incomes or properties?
Of course. We make simple and complex statements. We help you to optimize it legally and avoid errors or requirements.
Do you process inheritances and wills?
Yes. We can help you process wills, accept inheritances, obtain certificates and accompany you throughout the legal process.
Can you file appeals or writings if I have a problem with the Treasury?
Yes. We present allegations, appeals for reconsideration, writings and requests for instalments or deferrals, both for individuals and the self-employed.
How long does a procedure usually take?
It depends on the type of management. We tell you this from the beginning and we actively monitor it. We are committed to informing you at every step.
