Tax returns that leave nothing on the table.
A tax return is not a form to tick off but your chance to reclaim every euro you are owed. We use deductions and allowances to the full, file on time and check every assessment – and appeal when the tax office gets it wrong.
Every deduction & allowance used
Extended deadline via your advisor
Every assessment checked
Sound familiar?
For many, a tax return means: stress, deadline, back payment.
This is what we keep hearing from business owners and private individuals:
You suspect you're leaving money behind.
Deductions, flat rates, allowances – every year you overlook something. You just never know what, or how much.
The deadline always comes too soon.
Collecting receipts, understanding forms, everything by the cut-off: in the end you file under pressure – or not in time at all.
The assessment differs – and you don't know why.
The tax office strikes items or calculates differently. You can't judge whether that's correct – and the appeal deadline is running.
Prepayments and back payments catch you out.
Sometimes the tax office demands high prepayments, sometimes a hefty back payment lands. It never feels predictable.
Business and private blur into one.
As an owner, income tax, trade tax, VAT and the partnership return are all connected. Looked at separately, you give away links and money.
The late-filing penalty came anyway.
File late and you pay 0.25% of the tax per month, at least €25 (§152 AO) – money no one would owe with timely filing.
What we take off your plate
Every return you need.
Concretely, we prepare and take on for you:
Income tax return (Einkommensteuer)
For owners, the self-employed and private individuals – with all types of income, work-related expenses, special expenses and extraordinary burdens, fully used.
Corporation & trade tax (KSt, GewSt)
For your GmbH we prepare the corporation and trade tax (Gewerbesteuer) returns aligned to the annual accounts – including the trade-tax credit where it applies.
VAT return (Umsatzsteuer)
We prepare the annual VAT return, reconcile it with your advance returns and clarify input VAT, reverse charge and intra-community supplies.
Partnership returns (Feststellungserklärung)
For partnerships (GbR, GmbH & Co. KG) we prepare the separate and uniform assessment and allocate the results correctly to the partners.
Full use of deductions & allowances
Home-office flat rate, a home study, the saver's allowance, the investment deduction: we go through every item and get out what the law allows.
Assessment check & appeal
We check every assessment against our own calculation. If the tax office deviates to your disadvantage, we file an appeal on time (§347, §355 AO).
What changes for you
From obligation to refund.
With cleanly prepared returns, several things change:
You reclaim what you're owed.
Every permissible deduction is set, every allowance used. You pay no tax the law doesn't require.
More time until filing.
Through the advisor mandate your filing deadline extends considerably (§149 AO). No cut-off stress, no late-filing penalty.
No wrong assessment stands.
We check every assessment and appeal any errors. You pay what is correct – not what was estimated.
Prepayments that fit.
We set your prepayments realistically (§37 EStG) – the tax office neither ties up your liquidity needlessly nor leaves you facing a wave of back payments.
Business and private from one team.
Because we think all returns together, we use the links between company and private life – instead of giving them away.
You no longer have to think about it.
Deadlines, forms, receipts: that runs with us. You supply the documents digitally, we handle the rest.

A personal note from Karsten Guhr
To me, a tax return isn't a form but the last chance to claim what you're owed. What bothers me most is when someone leaves deductions behind under time pressure or simply accepts a wrong assessment – neither has to happen.
