BERLIN, Nov 21 (Reuters) - The German finance ministry expects a 2.2% increase in tax revenue for the full-year to almost 833 billion euros ($908.55 billion), it said in its monthly report on Tuesday, despite registering a small year-on-year drop in revenues in October.

The economy shrank by 0.1% in the third quarter but companies were looking in a "slightly less pessimistic way" towards the future, the report said. "The immediate outlook, however, remains cautious," it added.

Total tax revenues increased in the first ten months of the year by 2.3% to almost 665 billion euros.

Suffering a deep industrial recession, Germany has been among the weakest economies in Europe this year as high energy costs, weak global orders and higher interest rates took their toll.

The report echoed a forecast earlier on Monday by Germany's central bank, the Bundesbank, which said the country's economy would likely shrink again this quarter and experience an "arduous" recovery next year.
