Then zakah is paid on it all or separately if you are Shafi. The threshold that qualifies one to pay zakah was 90-100 grams of gold but now it is moved to 700 grams silver. So if you have that much wealth then you pay zakah. It is between 500-1000 pounds but check with a local scholar. Zakah is paid on monies but not everyday items. ie. Items in daily useage like cars and houses. Debts are taken away from the value of zakah but mortgages are not considered debt. Or else there would be few people who would pay Zakah.
There is zakah for farm animals, stock on sale and crops. There are more details that can be found in the books of fiqh, so please look them up there.
Where is the proof?
The categories that explain where those who are due zakah are in the following verse in Surah Tawba 9:60:
إِنَّمَا ٱلصَّدَقَاتُ لِلْفُقَرَآءِ وَٱلْمَسَاكِينِ وَٱلْعَامِلِينَ عَلَيْهَا وَٱلْمُؤَلَّفَةِ قُلُوبُهُمْ وَفِي ٱلرِّقَابِ وَٱلْغَارِمِينَ وَفِي سَبِيلِ ٱللَّهِ وَٱبْنِ ٱلسَّبِيلِ فَرِيضَةً مِّنَ ٱللَّهِ وَٱللَّهُ عَلِيمٌ حَكِيمٌ
You can clearly see masjids or other places have no right to Zakah.
Whom do you NOT pay zakah to?
Madrasas/masjids have no right to zakah.
