Corporate income tax returns
Nordlet turns your company's yearly profit and your recorded tax adjustments into the corporate income tax return of 30 European countries.
Corporate income tax is the tax a company pays on its profit. Once a year, the company sends a return that shows how that profit becomes the taxable amount, and how much tax is due.
The profit in the books and the taxable profit are rarely the same. Some costs, such as fines, cannot be deducted. Some income is not taxed. Losses from earlier years can lower the tax. The return lists each of these differences.
Nordlet works out that return from your books, so you start from figures that already match your accounts.
What Nordlet does
- Starts from the profit before tax in your books. Your income statement shows the same figure, taken from your general ledger.
- Lets you record each difference between that profit and the taxable profit on the Declarations → Tax adjustments page, for the year.
- Uses one calculation for every country's return. It adds and subtracts your tax adjustments, then applies donations and losses carried forward within the limits of each country's law.
- Puts the return's deadline on the company calendar and e-mails the owner, admins and accountants 7 days and 1 day before it.
- Where Nordlet sends the return, the deadline page has a File now button and then shows the status and the reference the administration returned.
The tax adjustments you can record
Each adjustment has a kind, an amount and, where the form needs it, the form's own code. The kinds are:
- Non-deductible expenses
- Income increase
- Non-taxable income
- Income outside the tax base
- Additional deductible expenses
- Donations
- Losses carried forward
- Investment project relief
- Foreign tax credited
- Tax reduction
The first five change the taxable profit. Donations count within each country's rules, either as a deduction from the profit or as a credit against the tax. Losses carried forward are deducted within each country's limits. Investment project relief cannot be more than the profit that is left. Foreign tax credited and tax reductions lower the tax itself.
How the return goes out, by country
The filing support table covers 30 countries. For the corporate income tax return:
- Nordlet builds the file and sends it in 12 countries: Austria, Bulgaria, Croatia, Czechia, Estonia, Finland, Hungary, Lithuania, the Netherlands, Poland, Romania and Slovenia.
- Nordlet builds the file and you upload it yourself in 16 countries: Belgium, France, Germany, Greece, Iceland, Ireland, Italy, Latvia, Liechtenstein, Luxembourg, Malta, Norway, Portugal, Slovakia, Spain and Sweden.
- You key in the figures Nordlet shows in 2 countries: Cyprus and Denmark. Their tax portals take the return only through their own screens.
In Estonia and Latvia, a company pays corporate income tax when it distributes profit, for example as dividends, and not on the profit of the year. The table lists those two as tax on distributions.
A few country details from the table:
- In Finland, Nordlet sends the financial statements as attachments to the return, and the Tax Administration passes them on to the trade register.
- In Ireland, Nordlet also builds the iXBRL financial statements that go with the CT1 return.
- In Germany, Declarations → ELSTER returns builds the file, which you send with your own ELSTER program. The German filing guide explains why.
Frequently asked questions
Do I need to record tax adjustments?
Only for the differences that apply to your company that year. The return starts from the profit in your books, and the adjustments you record change it.
Can Nordlet use my figures from an earlier system?
Bring the books over first. The migration guide shows how to move the chart of accounts, opening balances or full history into Nordlet. The return then starts from those books.
