It may be wise to hire a reliable tax consulting firm to handle all of your tax and social security issues if you are an independent contractor, consultant, or expatriate working abroad.
Select a tax consulting firm that can custom-tailor solutions for independent consultants, and make sure the service is knowledgeable about your financial affairs in the country you've chosen, has made all the necessary registrations and understands financial management issues specific to that nation.
Your chosen tax consulting firm can make sure that all rules are followed, that you register with the correct tax valuation to legally limit your social security and tax obligations, that you pay the right amount on time, and that you don't incur any late payment penalties.
A professional is probably already familiar with how to file returns, however you might have to spend hours researching the subject.
