Tax compliance and filing returns
We prepare periodic and annual tax returns, in line with your accounts and the reality of your activity.
Our Madrid-based tax advisers support businesses, the self-employed and individuals remotely throughout Spain. We do more than file returns: we examine your circumstances, explain the implications and assess the options before a decision or a response to the Spanish Tax Agency.

Our tax advice in Madrid starts with understanding what has happened, the decision you are considering and the documents available. We then assess the options and their consequences, coordinate accounting, employment or corporate advice where needed, and explain the next steps. The process can also be carried out remotely.
What has happened, what you want to do, the deadlines and the documents available.
We review the applicable rules and compare possible approaches, including their effects and obligations.
If accounting, employment or corporate matters are also involved, we address them together within the team.
We explain our assessment in plain language and agree how to proceed.
The starting point
To begin, tell us what you need to resolve, the period involved and any relevant dates. You do not need to send all your documents in the first message. Once the enquiry is defined, we explain which returns, supporting records, contracts or notices need reviewing and how to share them.
If you have received a notice, keep the full document and the details of its receipt. If you are preparing a transaction, distinguish decisions already made from those still open. This allows the case to be assessed without treating circumstances that could change as settled.

The first step is to identify what the authority is asking for, the deadline and the documents that may be relevant. We review the notice and work with you on the appropriate action.
I need help with a Tax Agency requestFrequently asked questions
These answers explain how we work. The precise scope always depends on the case and the available documentation.
No. MRC advises businesses and the self-employed on an ongoing basis and also helps individuals with specific tax matters. An income tax return, inheritance, gift or property transaction can be assessed without an ongoing advisory engagement.
Yes. Before you make commitments, we can review the proposed transaction, the people involved and the available records. The assessment compares options and tax consequences; it does not guarantee a particular saving.
Yes. We review the full notice, case reference, deadlines and related records before defining the appropriate response. A document request, representations and an appeal are different procedures, so the route indicated for the case must be checked.
Yes. Although our office is in Madrid, we provide remote tax advice to businesses, the self-employed and individuals throughout Spain. We can review enquiries, transactions or Tax Agency notices without you travelling to Madrid. The scope and documents required are agreed for each case.
Yes. You can request a defined enquiry, a transaction review or assistance with a Tax Agency notice. The issue, background documents and included work are agreed before starting, separately from ongoing support.
Fees depend on the work, records, complexity and whether support is one-off or ongoing. MRC needs to understand the case before preparing a proposal that distinguishes included actions from possible additional work.
Start by explaining the issue, relevant dates and any notice or proposed transaction. MRC will then identify the returns, supporting records or contracts needed and the appropriate sharing channel. Do not send tax, identity or banking documents through the initial form.
Accounting records and explains economic transactions; tax advice assesses their tax implications and related obligations. The two areas need consistent information but are not interchangeable. MRC can coordinate them within the agreed scope.
