In Spain, you can transfer money or other assets to your children or grandchildren during your lifetime, but these transfers can be subject to gift tax. Tax on gifts in Spain is payable at the time they are made.
However, many autonomous regions have special tax allowances or deductions for these gifts. In the Valencian Community, for example, each child or grandchild could be eligible to receive €100,000 without attracting any gift tax, whereas the tax on €100,000, without any allowances, would be at least €12,000. Also, gifting an asset now will mean that any growth on that asset will be free of any future inheritance tax.
The same allowance is available on inheritance, which means each child can receive €200,000 of your wealth, tax free, saving many thousands in inheritance and gift tax.
Gifting your property whilst you still live it in it, with rights to remain, is another option which many people consider. Known as usufructo, children will inherit the bare ownership of the property, possibly paying some gift tax now, but freeing property from the estate when considering inheritance tax.
As with most things relating to Brexit, what will happen next year is not known publicly at the time of writing. Also, it has been suggested that gift and inheritance tax is about to change in Spain. Therefore, if you are thinking of gifting money, or other assets to your children or grandchildren, this might be an opportunity that will not be around for much longer.
