Tax advice in Los Barrios for individuals, the self-employed and small businesses
Los Barrios is not a dormitory town. Its municipality includes the Palmones industrial estate, with the Acerinox steelworks, and around it work contractors, workshops, logistics companies and small businesses that depend on industry and on the port of the bay. On the other side are the town centre, Palmones, the housing estates and the countryside, with families who own a home, a plot of land or a rented shop.
That mix produces very specific tax cases: salaries with shift hours and bonuses, income from people who received unemployment benefit from the SEPE for part of the year, self-employed workers who invoice a single company on the estate, and owners of a property who do not know how to declare it.
If you are looking for a tax adviser for Los Barrios who gives you clear information before anything is filed, Asesoría Serra is a team of tax advisers and lawyers. The same person handles your file from start to finish and tells you the result, and where it comes from, before filing. That way the advice fits each client and you know exactly what you are signing.
Spanish income tax return in Los Barrios: shifts, furlough (ERTE) and a second payer
People who work shifts in industry usually have a high, stable salary, and that is not the problem. The problem appears in the year when there was a furlough scheme (ERTE), long sick leave, a change of contractor or a spell of unemployment: the SEPE or the mutual insurer counts as another payer and the return changes.
For the 2025 tax year there are three thresholds. A single payer: you do not have to file up to 22,000 euros gross. Several payers, when the second and later ones add up to more than 1,500 euros: the threshold drops to 15,876 euros. Registered as self-employed, even for one day: you must file in any case.
What we do on every income tax return:
Review of the draft. We compare Hacienda’s tax data with the certificates from your employer, the SEPE and your bank. Withholding and payer errors are the most common, and we ask for the information to be corrected when a certificate does not match.
Spanish and Andalusian deductions. Renting your main home, large family, disability, education costs or buying an older home, only if you meet the requirements.
Property and sales. Rentals, deemed income from a second home and the gain from a sale, each in its own box.
Previous years. If we find a mistake in a past return, we consider a correction or a supplementary return before Hacienda finds it.
The self-employed and small companies in Los Barrios: quarterly returns without surprises
Many self-employed people in Los Barrios work for industry: maintenance, assembly, transport, industrial cleaning or technical services. They invoice few companies, sometimes only one, and VAT and income tax pile up if nobody keeps track.
We handle the tax side of your business, so that you can focus on running it:
Tax register. Registrations, de-registrations and changes with Form 036 or 037, choosing the right business activity code (IAE, which is not the same as the CNAE activity code, although they are often confused) and VAT scheme.
Quarterly forms. VAT on Form 303 and income tax payments on account on Form 130, calculated from your invoices and filed on time.
Annual summaries and income tax. Form 390 in January and your business included in your income tax return.
How your income changes. Every quarter we compare your invoicing with the previous year and, if there is a big change, we adjust the figures so that the payments on account and the income tax return bring no surprises.
Deductible expenses. Vehicle, tools, allowances or utilities: what can be deducted, in what proportion and with which receipt.
For setting up a limited company (S.L.), including its registration at the Companies Registry (Registro Mercantil), we have a separate page. →
IBI in Los Barrios: the bylaw rates and the reductions you have to apply for
The annual property tax (IBI) in Los Barrios is governed by tax bylaw number 2, last amended with effect from 1 January 2025. The rates it sets are:
Two details that are often overlooked:
Large families. There is a 45 % reduction of the tax for the main home, but you have to apply for it: it is not applied automatically. The application is made between 1 January and the last day of February, and the family must be registered as living at that home.
Payment in two bills. The tax is charged in two instalments of 50 %, although it can be paid in full with the first one.
If you buy, inherit, extend or change the use of a property, you must declare it to the Land Registry office for property values (Catastro) within two months. In Los Barrios this can be done at the Town Hall’s own Catastro office. An outstanding Catastro update carries over to the IBI, the income tax return and the plusvalía.
Homes and other urban properties: 0.60 % of the cadastral value. Non-residential urban properties with a cadastral value from 100,000 euros: 1 %. Rural land: 1.16 %.
Municipal capital gains tax and property deeds in Los Barrios
Selling, giving away or inheriting urban land in Los Barrios brings the municipal capital gains tax (plusvalía municipal) with each transaction. The town charges it under its bylaw number 6, updated in 2022 after the Constitutional Court ruling. The taxpayer can choose the calculation with coefficients or the real gain, and a sale at a loss pays no tax if both deeds prove it.
The deadline to declare it is 30 working days for a sale or a gift, and six months for an inheritance, which can be extended on request.
Los Barrios has its own notary’s office for signing. As for registration, the town is assigned to Land Registry number 2 of Algeciras, and the land registry extract (nota simple) of each property settles any doubt.
When the property comes from an inheritance or is about to change hands, it also goes through our legal team: inheritance in Los Barrios and the surrounding area and buying and selling homes in Los Barrios and nearby.
Plots and country houses in Los Barrios: Catastro before Hacienda
A large part of the municipality lies within the Los Alcornocales Natural Park. In that countryside there are farmhouses, working farms and plots with old buildings that often appear incorrectly, or not at all, in the Catastro and the Land Registry.
Before you declare a rental, sell or divide an inheritance, we check three things in your file: the class of land (urban or rural, which changes the IBI rate from 0.60 % to 1.16 %), whether the building is registered and who appears as the owner. If something does not match, we propose solutions: what is worth regularising, in which order and with which documents.
Hacienda from Los Barrios: tax notices, reviews and the electronic mailbox
On the Spanish Tax Agency’s map, Los Barrios comes under the Algeciras office (Cádiz regional office), at number 85 Avenida Virgen del Carmen. It covers every tax address in the town, starting with the town centre, 11370 Los Barrios. You rarely need to set foot in it.
With your power of attorney or your digital certificate, we file on your behalf and watch your electronic mailbox (Dirección Electrónica Habilitada) so that no notice expires unopened. If a letter has already arrived, bear in mind that the deadline to reply runs from the date of notification, usually ten working days. Send us a photo and we will tell you what they are asking for and how to reply.
If a review has already been opened, or there is a proposed correction of your return or a penalty on the table, the case goes to our tax lawyer. →
Los Barrios residents with a salary in Gibraltar

A typical case in Los Barrios
A worker at a contractor on the industrial estate spends three months on furlough and then changes company. The following spring the draft return shows he has to pay and he does not understand why, if his salary has not changed.
With the certificates in front of us, the explanation appears: three payers, with more than 1,500 euros between the second and the third, while each company withheld as if it were the only one. We adjust the tax, add his deductions and tell him how to ask for more withholding on his salary so that it does not happen again the following year.
