The goal of income tax prepayment is to pay 100% of your tax in advance, in order to get a tax bonus (or avoid a penalty, depending on how you look at it).
You can pay gradually in 4 installments of 25%, or make a higher initial prepayment the first quarter.
Prepayments are only optional for the first 3 years of your freelance activity.

By default, the app will suggest a prepayment amount based on the estimated taxable income. This can be done in 2 ways:
automated projection based on encoded revenue/expenses in the app
you can override this by entering your yearly taxable income manually, like shown below

You can decide at any time to revise the amount of prepayment you make (the app gives you and indicative information only).
In the app, when you mark the prepayment item as 'paid', you can simply input the amount that you have paid to the tax office.
If you didn't make any prepayments, you can enter "0€".

Everything was great! All my questions were answered quickly and in a friendly manner.
In the world where everyone seems to be out to get small entrepreneurs and overwhelm them with new rules, more taxes and reporting obligations, Accountable often feels like the one steady partner that actually wants you to succeed, providing quick, clear and personalised support. Thank you!
This is an amazing application with great support on issues. In short as in day I am addicted to it (in a positive way). I myself is from IT project management and the way they have captured the user requirement, it’s phenomenal.
UI is great. Feature packed and very easy to use. The team at Accountable were VERY quick to respond and their team of technicians soon had a fix in place. Very happy with the level of service so far. Thumbs up from me!
This program is a lifesaver, and it is always improving. Plus, it has an AI chat feature that is actually useful.
The coaching session on tax management was excellent, good material, excellent explanations and very insightful. Combined with the AI I never feel alone with Accountable.
The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.
Fast and careful answers from Alina. Top service. Thank you.
They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
