Calculating zakaat

Q: I live in the UK with one kid. My kid's dad lives in another country. Because I am a single mum and have no job, I receive some benefits from the government. I use that money for my and my kids's expenses. I don't work so I don't have anywhere alse to get my zakaat money from. Now my question is can I pay my zakaat from that money (which I receive from the government). Also I sometimes give sadaqa from that money. Is my sadaqa valid? Will Allah accept that sadaqah? The other thing I would like to know is how much money do I need to give in zakaat for gold, and cash?

Q: Is there zakat on GP Fund which is a fund for government employees?

Q: Is zakaat compulsory on the capital amount in a mudhaarabah transaction?

Q: I have two small flats. First one I bought with the intention that I have a house to live on. Later I bought a second one and changed my intention to sell them both after some time to buy a house for me. Both are rented. I want to know.

1. How much zakat I have to pay now.

2. If I use the rent for my retirement money to live without work how do I have to pay zakat?

3. If I sell them and buy a house and start living in it and partly rent it to get money to survive in old age, how should I pay zakaat on it?

Q:

1) Is it permissible for a person to change his zakaat date to an earlier date due to him e.g. being out the country on a yearly basis at the same time he was supposed to pay zakaat?

2) If someone doesn't know what exact date he became baaligh on, how should he set the date for payment of his zakaat?

Q: I belonged to a Pension Fund at work however it was disbanded and I moved the monies to a retirement annuity. This money is only available to me at age of 55. I have been told that I need to pay zakaat on it annually. The amount is substantial and I cannot afford to pay this annually. Why do I have to pay zakaat if I am not able to use the funds until 55 years?

Q: I understand that Zakaat is not payable on an extra house. But if the extra house is rented and I am not receiving the rent because I live abroad
and my parents/brothers receive the rent and spend the rent to fulfill their needs. Do I still have to pay Zakaat on the rent?

A: No

Q: Does a person have to pay zakaat on an extra house he bought and which is rented out? Similarly does one have to pay zakaat on the rent?

Q: My question is for zakaat, wealth should remain with a person for an "entire lunar year" then zakaat becomes wajib. My question is if a person has one million which remains with him for an entire lunar year, zakaat becomes wajib on him but if he gets half million one week before his zakaat date, does he need to pay zakaat on one million or 1.5 million. Please clarify. (Please note that half million which the person received did not remain with him for an entire lunar year).

Q: The condition of Zakaat is that "One should have amount equal or greater than Nisaab amount for more than one year before Zakaat can be paid". My question is, if person receives extra money upon which one year has not passed; does he need to pay Zakaat on this extra money too which does not meet the requirement of "one year old"? Please clarify if zakaat is due only if the amount has been in one's possession for more than a year?
