slimboyfat - If JWs were in receipt of grants from governments this information would be public. Where is it?
In the United Kingdom their accounts are public and there is no sign of income from grants or government schemes. (Maybe there are some very small instances, but so tiny to be insignificant to overall finances. However even this has not been shown.)
Watchtower Britain takes advantage of the following government scheme: Gift Aid.

From Wikipedia
"Gift Aid allows individuals who are subject to UK income tax to complete a simple, short declaration that they are a UK taxpayer. Any cash donations that the taxpayer makes to the charity after making a declaration are treated as being made after deduction of income tax at the basic rate (20% in 2011), and the charity can reclaim the basic rate income tax paid on the gift from HMRC. For a basic-rate taxpayer, this adds approximately 25% to the value of any gift made under Gift Aid. Higher-rate taxpayers can claim income tax relief, above and beyond the amount claimed directly by the charities. The rate of the relief for higher-rate taxpayers in 2011 is usually 20%, the difference between the basic rate (20%) and the higher rate (40%) of income tax, although recipients of dividend income (taxed at 10% and 32.5%) can achieve a higher rate of tax relief (22.5%)." - https://en.wikipedia.org/wiki/Gift_Aid
