TaxDown rocks and it’s much cheaper and less expensive than the tax attorneys I have used in the past. They have optimized their use of AI and human customer support very effectively.
Terrible. I paid a full package and I had to rush to another asesor the last 2 days before lodging the renta because TaxDown completely missed my data. They're a very dangerous company. Unless you're... See more

Without TaxDown I would not have successfully become an Autonomo!
The Team at TaxDown has been incredibly helpful in setting me up as an Autonomo. The team was incredibly patient and supportive throughout the process, answering all my questions and managing the relationship directly with the Tax Agent. Without TaxDown, I am not sure that I would have succeeded, and I know that it would have taken a lot longer than leaving it to the experts at TaxDown!

simple and effective
The process is quite simple and effective. The User interface is very clean and all the parameters are explained with clear examples.
With TaxDown, we have options to file the IncomeTax returns before the official start date, which is very good.
Unauthorized charges and misuse of personal data
I experienced unauthorized charges from this company without having an active subscription or having given consent. Even more concerning is that the charges were made using banking details I never knowingly shared with them.
This raises serious concerns about how personal and financial data is being obtained, stored, and used. Transparency and consent are fundamental when handling customer information, and in this case, both seem to be lacking.
Additionally, customer support has been unhelpful — responses appear to be automated, and I have not been able to get a proper answer from a real person regarding this issue.
I have requested a refund and the deletion of my data. Situations like this undermine trust and should be addressed immediately. I strongly advise others to be cautious.

They are crooks and lying
They are crooks
I subscribed for the full contract 239 euro and asked before if it includes moedelo 720 and 721 they confirmed after that they charge me 250 euro only for a simple 721 form with 21 coins I delivered everything so this is a very bad company .
Luckily a canceled everything 1 day later before the 14 days where over they haven too pay me back ,if they do not pay me I will take legal action .

I honestly regret paying for this service.
I honestly regret paying for this service.
I booked and paid for a consultation expecting a professional, modern setup. No link, no video call, no clear instructions. At the last minute I’m told the advisor will call me by phone, which is useless when you don’t have good coverage at home. This was never made clear upfront.
When I explained that I needed the appointment online, the response was dismissive and unhelpful. After paying, it’s almost impossible to find available appointments, and when you finally do, the experience feels improvised and poorly managed.
Great service. Atención excelente.
Although you never know which staf will be answering to your email and reply I got an excellent service from text down and excellent resolution.
Mientras que nunca se sabe cuál agente te va a atender a tus emails, he tenido un servicio excelente y una resolución excelente from tax down.
Tax down not recommended
I paid my subscription plan one month before the tax declaration was to close and i explained my situation to them.
I was in contact communication with them to provide all the informations to make my tax declarations for the past years with my crypto assets.
They didn´t do the job with the crypto declaration to the end and told me that they will do it after i present my declaration for this year.
I had to write to them serval times for them to correct the errors made in the calculation, until today 29/11/2025 i am still waiting for the correction and they keep saying the department is checking for the errors and nothing. more than 500€ gone.
The customers service and service is not recommended. The worse is that they keep changing the financial advisors and you have to explain from the beging each time a new advisor comes up and which solution do they give...
If you value your time, money and mental health look for other companies...
Wrong calculation and bad customer support
Calculation said I would need to give back 650 euros. Did the exact same calculation with the official RENTA page and it turned out that they would have to give me back 200 euros.
They did not want to give the money (45€) for the app as they have “done their job”.
I worked in Customer Support most of my life and I know bugs and issues can happen any time. They took zero ownership and therefore I cannot recommend the app to anyone.
Charged twice for subscription this year (and not only me)
I have a pretty straightforward case in terms of taxes, so paying for a Full package is an overkill. I initially subscribed to "Expert" package last year, but this year they removed this plan and moved everyone automatically to "Full" plan, allegedly with the same price.
However, they charged me twice this year, once when I submitted application and another time by the same date of my last year's subscription. They don't seem to have acknowledged or fixed a technical error, because some 3 months later the same thing happened to people I have recommended Taxdown to.
I imagine they charged a lot of people twice and if you check your transactions regularly you will see it, but imagine if you don't!
I am overall satisfied with the service, but pricing and payment strategies are buggy and almost feel like a scam. I can't keep recommending a service that would charge you twice and say nothing until you notice.
This app really helped me a lot…
This app really helped me a lot especially (Declaración de la renta). At first I didn’t know what to expect but thanks to the staffs who responded within 24h and explained everything to me. Am really satisfied and happy thanks a lot.
Super fast and easy to work with
Super fast and easy to work with. Thanks so much!!

Doesn't allow you to add key details, forces you to pay more
They have changed their process to get more money from you. Last year I was able to add how much I pay towards my pension very easily. This year they have taken it away, they have been very vague over email and then I have been forced to pay extra to access their chat service (something which was available previously). Even after accessing the chat they still cannot help me! They keep telling me add how much you have received and not understanding that I am the one who is paying.
I will be cancelling my subscription, stay away and just hire a gestor. They have made this process unnecessarily complicated

Generic and not giving right information creating a time crunch
Not impressed by the service. I have a special tax situation and asked one month ago what I need to do. I had to get more documents which I did and the day I received them shared them (one week ago).
Today I followed up and was told that the information I was given was not correct. It seems the "Adri" that responds to mails is a bot and the company should not mislead their customers but thinking they are taken care of.
Now one week is left and I was told I need to take extra steps which I easily could have initiated one month ago without time pressure.
My impression so far is not great - paying that much money for a FULL subscription you at least expect correct answers. I rather wait a bit more for a correct answer than being fed generic answers in a minute that give wrong information.

Always ask for more money
Always ask for more money
I paid the most expensive subscription (Full) from the ones they offered, then because they say your situation is more complicated, they ask you to pay 3 times more!!! No option to cancel. Why they don't ask these 2 questions before you pay the first time to give you the correct amount first? (to trick people! not honest). And they already knew my situation from previous years :(
Service works, but they could be more honest and transparent, without using cheap "marketing" tricks.
