We have gathered 32 questions frequently asked by residents, non-residents, property buyers, freelancers and companies. Each has its own page with a full answer. If you cannot find yours, write to us and we will respond without obligation.
Taxation
Taxes for freelancers, companies and individuals
Returns, deadlines, documents and how we handle the taxation of residents and those living abroad.
TaxationYes. We regularly work with clients who live outside Spain and manage the entire relationship remotely: documents are sent digitally and communication is by email, phone or WhatsApp, in Spanish, English or Russian.
Read the full answerIt depends on your situation: a resident with a salary is not the same as a non-resident with a property or a freelancer with activity. After an initial consultation we send you a specific, personalised list, without asking for documents that are irrelevant to your case.
Read the full answerYes. You can hire a specific tax consultation — for example, to resolve a question before buying a property or moving to Spain — without needing a recurring service. If you later want continuity, we can arrange it.
Read the full answerThe resident income tax return (IRPF) is generally filed between early April and 30 June of the year following the tax year being declared. The exact dates are set each year by the Agencia Tributaria; if the return is payable and paid by direct debit, the deadline ends a few days earlier.
Read the full answerA self-employed autonomo in Spain mainly pays personal income tax (IRPF, with quarterly payments on account save for some exceptions) and VAT (IVA, filed quarterly), and also submits the annual information returns and any withholdings applied. On top of that comes the monthly autonomo contribution to Social Security, which is not a tax but is a recurring obligation.
Read the full answerAccounting
Accounting and periodic obligations
Digital invoicing, switching firms and coordination between accounting and taxes.
AccountingYes. You can send us issued and received invoices in digital format and organise them with us. Depending on your activity volume, we suggest the most convenient way, without paper or travel.
Read the full answerYes. We review the starting position, identify what is missing or should be corrected and tell you clearly what needs to be regularised before we continue. Changing firm does not have to interrupt your ongoing obligations.
Read the full answerYes. At Asistenio the tax and accounting departments work together, so returns are prepared from accounting records we know first-hand. This avoids poor coordination, duplicated work and mismatches between the books and the returns.
Read the full answerNon-residents
Non-resident income tax and fiscal representation
What obligations you have if you own property or earn income in Spain without living here.
Non-residentsYes. An important part of our work involves serving non-resident clients: we prepare the non-resident income tax return (Form 210) and act as annual fiscal representative before the Spanish Administration.
Read the full answerIt means we act as your contact with the Spanish Administration: we receive and respond to communications related to your obligations, file your returns and ensure no requirement goes unanswered while you are abroad.
Read the full answerNo. We regularly work remotely with clients who live in other countries. Engagement, sending documents and consultations are all handled digitally; if any particular step required your presence or a specific authorisation, we would tell you in advance.
Read the full answerYes. Tell us your case: we review what obligations you had in each tax year, calculate what is owed and explain your options frankly. Regularising voluntarily, before the tax office demands it, significantly reduces surcharges and penalties.
Read the full answerForm 210 (Modelo 210) is the Non-Resident Income Tax (IRNR) return for those who earn income in Spain without being tax-resident here and without a permanent establishment. It is filed, for example, by non-resident owners of a home — whether they rent it out or use it themselves — and by anyone selling a property in Spain.
Read the full answerReal estate
Buying a property in Spain
Land Registry entry, costs, municipal procedures and support during the purchase.
Real EstateYes. We prepare and process the purchase: we request the nota simple from the Land Registry, review the property documentation, handle habitation certificates and licences at the town hall and support you through the notarial process, so the transaction moves forward with legal certainty.
Read the full answerThe nota simple is the informational document from the Land Registry showing who owns a property, its description and the charges affecting it (mortgages, attachments, easements). We request it before moving forward with any purchase, to check that the seller is entitled to sell and that the property holds no surprises.
Read the full answerYes. We handle habitation certificates (cedulas de habitabilidad), building and activity licences and other municipal procedures linked to the property, both during the purchase and afterwards, when you want to renovate, rent out or change the use of the home.
Read the full answerYes. It is actually the best time to talk: we explain what documentation to review for any property you are interested in, what costs and taxes the purchase will involve and what obligations you will take on as owner.
Read the full answerBesides the price, buying a home in Spain involves taxes — transfer tax (ITP) on resale property, or VAT plus stamp duty (AJD) on new builds — as well as notary fees, registration at the Land Registry and, where applicable, gestoría and valuation fees. As a guide, these costs usually come to between 10% and 15% of the price, depending on the autonomous region.
Read the full answerNIE & immigration
NIE, documentation and timelines
How to get the NIE, how long it takes, what documents are needed and whether it can be done from abroad.
NIE & ImmigrationYes. We manage the NIE (Foreigner Identity Number) application and related immigration procedures: we review your documents, prepare the application, manage the appointment and tell you exactly what you need to present and where.
Read the full answerIt depends on the type of application and the office processing it: in some cases the NIE is assigned during the appointment itself; in others the decision takes days or weeks. The factor that most often delays the process is appointment availability. Once we have reviewed your case we give you a realistic estimate and let you know if anything changes.
Read the full answerIn certain cases, yes. The NIE can be applied for from abroad at the Spanish consular office in your place of residence or, in some cases, through an authorised representative in Spain. We confirm whether your situation qualifies before starting anything.
Read the full answerAs a general rule: the official EX-15 form completed, a valid passport (original and copy), a document justifying the reason for the application and proof of payment of the fee. Requirements vary according to your nationality and the reason, so we send you a personalised list once we have reviewed your case.
Read the full answerDigital certificate
Obtaining, using and renewing it
What the digital certificate is for, how to get it and what to do when it expires.
Digital CertificateIn certain cases, yes. The identity verification required for a digital certificate is normally done in person at a registration office, but in some cases it can be completed remotely — for example with an electronic DNI or by video identification. We confirm which route is available to you before starting the procedure.
Read the full answerIt works for the vast majority: with it you can identify yourself and sign on the electronic platforms of the Agencia Tributaria, Social Security, the DGT, town halls and many other public bodies. Some specific procedures also require you to appear in person or to hold a particular type of certificate; if that applies to your case, we will tell you.
Read the full answerWhen it expires, the digital certificate is no longer valid for identifying yourself or signing, and you lose access to online procedures until you renew it. That is why it is best to renew before the expiry date: in many cases this can be done online without verifying your identity again. If it has already expired, you have to apply for a new one.

Notarial signing and sworn translation
Support at the notary, prior documentation and when a sworn translation is needed.
NotaryYes. We can accompany you to the signing and coordinate the entire notarial procedure: the appointment, the prior documentation, the review of the draft deed and, if needed, interpreting in English or Russian during the signing. Tell us about the transaction and we will explain how we would organise it in your case.
Read the full answerYes. We review what documentation your transaction requires, gather it with you and verify it is complete and valid before the appointment. A signing delayed by a missing document means avoidable costs and delays.
Read the full answerA sworn translation is carried out by a sworn translator-interpreter authorised by the Spanish Ministry of Foreign Affairs and carries their signature and seal, which gives it validity before official bodies. A simple translation has no such validity. You need a sworn translation whenever a foreign document is submitted to an administration, a notary, a court or a registry in Spain.
Read the full answerWe usually work in Russian and English; for other languages, ask us and we will confirm availability. And yes: we normally coordinate the sworn translation within the same file as the procedure you are handling with us, so you do not have to look for a translator yourself.
