A tax adviser who knows the Campo de Gibraltar
Asesoría Serra is a firm of tax advisers and lawyers in La Línea de la Concepción. As tax advisers in La Línea, we help individuals, the self-employed, small businesses and companies to meet their tax obligations, pay what is due and avoid mistakes that cost money later.
We work on personal income tax (IRPF), corporate income tax, VAT, wealth tax, non-resident taxes, property and inheritance taxation, and tax and estate planning.
We work in a border area: tax residence, income from Gibraltar and double taxation are part of every day. We listen to what you need and give you solutions, not just information.

Spanish income tax return in La Línea and online
We prepare and file your income tax return (declaración de la Renta) so that you do not pay more than you should or get a surprise tax notice months later. We check your tax data, apply the Spanish and Andalusian deductions you are entitled to and explain the result before filing.
We also correct returns from previous years, file supplementary returns and ask for corrections when you have been refunded less than you are due. We see you at our office in La Línea or remotely, from anywhere in Spain: you send us the documents and we file the return.
Tax management for the self-employed, companies and small businesses
We handle the tax side of your business and follow it throughout the year: what has to be filed, when, and how to pay tax in the best way. We do not do payroll or monthly bookkeeping; if you already have someone for that, we work with them.
Registration and obligations
Tax registration (Form 036 or 037), business activity code (IAE), CNAE code and invoicing and record-keeping obligations.
Quarterly VAT and income tax
Forms 303 and 130 and each quarter’s withholdings, filed on time and checked before payment.
Corporate income tax
Preparing and filing the tax, payments on account and reviewing the year’s result.
Individual or company
We compare the tax on each option according to the size and outlook of your business.
Spain–Gibraltar taxation: cross-border workers and tax residence
The border creates situations involving both territories every day: cross-border workers, tax residence, income earned in Gibraltar, companies and double taxation.
Each case needs its own analysis, because the answer changes depending on residence, activity and type of income. We study your situation and tell you what you must declare in Spain and how to avoid paying twice.
Direct, personal service
Each matter is handled personally by our advisers, with care, discretion and direct communication. We are a small team, and that helps: the same contact person and real follow-up of your case. We explain your situation clearly and support you in each decision.

Frequently asked questions about our tax adviser in La Línea
Your situation is not listed here? Tell us on WhatsApp which taxes concern you and we will reply.
What does a tax adviser do?
They tell you which taxes apply to you and how to pay the right amount, file your returns on time and represent you if the Spanish Tax Agency writes to you. They also help you plan before a decision with tax consequences: selling a property, setting up a company, making a gift or changing your residence.
Do you only handle paperwork? Do you do bookkeeping?
We do the tax work people usually look for in an administrative agency (gestoría): income tax, self-employed registration, quarterly VAT and income tax, corporate tax, the Junta de Andalucía forms and dealings with Hacienda and other bodies. We do not do payroll or companies’ monthly bookkeeping; if you already have someone for that, we work with them.
Where is Asesoría Serra?
At Calle Cervantes 2, entreplanta, despacho 4, in La Línea de la Concepción, next to the border with Gibraltar. We see clients by appointment and also by video call.
Do you work with people who work in Gibraltar?
Yes. We look at your tax residence, the type of income you earn in Gibraltar and what you must declare in Spain, including double taxation situations.
Do you advise non-residents in Spain?
Yes. We advise non-resident individuals and entities with income or assets in Spain: NIE, tax representative, Form 210 and other obligations, especially when there are links with Gibraltar or the United Kingdom.
What documents do I need for my income tax return?
Your ID, the reference number or tax data from the Spanish Tax Agency, withholding certificates, mortgage or rent receipts if they apply, and the documents for any sale, inheritance or one-off income during the year. If anything is missing, we will ask you for it.
Do you advise on wealth tax and assets abroad?
Yes. We prepare the wealth tax return and Form 720 for assets abroad, and check that what you declare matches your income tax return to avoid problems and penalties.
Do you offer online consultations?
Yes. You write to us on WhatsApp or through the form, we agree a day and time, and in the video call we review your situation and tell you the next steps. You can book on the online consultation page.
What should I do if I made a mistake in a return I have already filed?
If the mistake made you pay too little, it is corrected with a supplementary return; if you paid too much, you ask for a correction so that Hacienda refunds the difference. Doing it on your own initiative, before a tax notice, avoids the penalty and leaves only a late-filing surcharge. We review the return, calculate the correction according to the complexity of the case and your taxpayer profile, and file it.
What is Verifactu and when does it affect me?
It is the Spanish Tax Agency’s verifiable invoicing system: the software that the self-employed and companies use to issue invoices will have to meet certain requirements and, under the Verifactu option, send the records to Hacienda. The start dates have been postponed; if we handle your taxes, we will tell you the date that applies to you and check that your software complies.
What rights do I have as a taxpayer before Hacienda?
Among others, the right to be informed of the procedure and its deadline, not to provide documents the authorities already have, to submit a written response before the decision and to appeal. Knowing them avoids replying badly or late.
What should I do if I receive a tax notice from Hacienda?
Do not reply automatically or let the deadline pass. Send us the whole letter and we will tell you which procedure it is and how to reply. More information on letters from Hacienda.
