What PortoDoc does with your mail
Everything on this page is included in your plan at no extra charge. The AI hints are non-binding – the original letter counts.
Authorised recipient for the tax office
You can name PortoDoc as your authorised recipient with the German tax office; your mail then comes to our address in Ahrensburg near Hamburg.
The tax office can require this from companies outside the EU and EEA (§ 123 AO). Online sellers on marketplaces name one with their application for VAT registration (§ 22f(1) sentence 2 UStG).
Limit: For one authority in Starter, for any number from Business. We only receive letters; you make statements and objections yourself.
Every letter explained
For every letter you get a summary in two or three sentences: who wrote it, what it is about and what to do.
The traffic light shows how urgent it is: red means deadline or urgent, yellow action needed, green for information only.
You can read German letters in English in all plans.
Limit: AI-assisted and non-binding; the original letter counts. Not legal or tax advice.
Help with deadlines
From Business, the deadline found in the letter appears next to the traffic light and on its own deadlines page in your account.
If the date is written in the letter, you get an email 7 and 2 days before it expires. In it, you mark the deadline as done or report that it is wrong.
Limit: The AI reads the deadline from the letter, without guarantee: it can be missing or wrong. Check it yourself or with your tax adviser – we do not monitor deadlines for you.
Filing and search
Create your own folders and tags, search the full letter text and add notes to a letter.
Download several letters as a package: a ZIP with an overview and all summaries.
Limit: A package holds up to 200 letters. The download link works for 15 minutes and only while you are signed in.
Rules: if …, then …
Let new letters sort themselves: if a letter comes from the tax office or has a deadline, then into a folder, with a tag, to your tax adviser or marked as done.
Up to 20 rules per account; each rule can do up to five things.
Limit: A rule only applies if the AI detects the feature, such as sender, type of letter or deadline. If it is missed or misread, the rule does not apply or applies differently.
Forwarding to your tax adviser
Send a letter with its summary by email to your tax adviser: one at a time, up to 20 at once or automatically by a rule. Replies come straight to you.
You add up to three recipients. Each one agrees once via a link – nothing is sent before that.
Limit: The email is encrypted in transit, but not end to end. If a letter does not fit into the email, it comes as a link valid for 72 hours.
Team account
Invite management, colleagues or bookkeeping, each person with their own login.
You decide who only reads, who edits and who manages. The access log shows who opened which letter.
Limit: Up to 10 people per account; an invitation is valid for 7 days. Contract, payment, authorisation and deleting the account stay with the owner.
API – on request
Bring letters and deadlines into your own tools: a REST API, a webhook for every new letter and a calendar feed for detected deadlines.
We enable the API for your account on request. You then create up to three keys.
Limit: Webhooks carry only IDs and metadata, no letter content. You are responsible for the tools you connect.
