In the Netherlands 36K is a decent salary for 5-8 years experience in technical positions in IT. Belgium has a similar economy and taxation. I get by on that living near Amsterdam, but I'm a single person household (which also brings extra expenses of course as most things in stores are packed for 2 or more people so I get a lot of leftovers).
AFAIK the taxation is like it is over here which is staggered.
Do inquire after benefits. Health insurance and pension fund are pretty much standard for companies to provide, you might also qualify for a company car (in which case watch out for special tax on those) and/or other extras.
Belgium with around 50-53 % income tax is supposedly highest among european countries and may be in the world. I you are planning to live in Antwerpen with your family be ready to shell out around 700-900 euros for accomodation.
I'd guess (not sure what it's now) about 2500 a month before taxes (that's ex benefits of course).
Tax rate for expats is I think about 25% (35-60% for natives depending on income), you'd best check with a consulate or embassy for the exact rates.
Sudharsan, you will probably find that on 3k a month you're left with about 2k a month after taxes. As an expat that may be even higher as expat tax rates are lower. Again, check the Belgian consulate or embassy nearest you for details. They'll be able to tell you all the rates and probably will be able to make a sample calculation for you (if the company you're planning to work with can't supply that). For 2 people it's not a lot, but you can live decently on it if you have no expensive hobbies and don't spend a lot in restaurants and pubs (of which Belgium has many). And maybe your spouse can also find a job (maybe parttime), increasing your income.
Possibly that's part of it. Another reason might be that for decades European governments tried to attract foreign workers to their shores to fill the shortage in labour and the lower taxation was an incentive for that, and has since remained due to inertia (hard to change a status quo once established).
I've planned moving to Netherlands or some places nearby like Belgium. I've sent some CVs to companies there and even to my company who has an office and now still waiting for the response. What are my chances who has 3-4 yrs experience in java doing intermediate level of works now in J2EE? Will there be good opportunity now there to hire an expat or a non-Euro IT staff?
There's a lot of unemployment among IT workers (including Java experts with more experience than you have) in the Netherlands.
On top of that people are getting wary of foreigners taking away jobs from locals. This has now reached government levels and there's calls going out to the responsible agencies to greatly reduce the amount of work permits handed out.
I agree with Jeroen, that it must be a lot more difficult to find EU IT job for foreigners than 4 years ago. Consultant-like part at least of my job has been becoming more important. Might be true for a lot more jobs. Its not only language. You have to somehow "empatize" with customers which is much easier if you know local customs very well. And fear of jobless is so whitespread that there might be more risk of xefonic-like reactions from customer side if they are confronted with recently arrived.
