How it works

Four steps, from start to receipt

You see the whole path before you begin.

  1. 1

    Create an account (no card).

    Email and password are enough. No payment details, no commitment.

  2. 2

    Answer the assistant's questions.

    The assistant asks in plain language and fills in the forms for you.

  3. 3

    Pay €24.99 when you submit.

    You see the result first. Decide against it and you pay nothing.

  4. 4

    Receive the ELSTER transfer receipt.

    Proof of submission then sits in your account.

Refund estimate

You know the outcome before you pay

As you fill things in, Solobooks calculates your estimated refund. The figure is there before payment — you are not buying on hope.

  • Updates with every entry
  • Shows which entries change the amount
  • No payment and no submission without your confirmation

2 questions open

Submitting and paying happen only in the last step.

Scope

What the assistant covers — and what it doesn't

So you know in two minutes, not after two hours.

What Solobooks is built for

The assistant takes you through these cases in full.

  • Employment income (Anlage N)
  • Self-employment (EÜR)
  • Joint return for married couples
  • Children
  • Insurance and pension contributions
  • Special expenses
  • Household services
  • Extraordinary burdens
  • Home office
  • Wage replacement benefits

What you'll need something else for

The assistant cannot record this income. We say so here so you don't get stuck halfway.

  • Investment income (Anlage KAP) Not covered — e.g. interest, dividends, share sales
  • Rental income Not covered — income from let property
  • Pensions (Anlage R) Not covered — state and private pensions

If any of these three applies to you, our assistant is not the right tool. A tax advisor or a program with the full range of forms will serve you better — even though it costs us the sale.
