Hi I came across these posts and thought my reply may be of help I went through criminal charges from tax credits my situation wasn't correctly reported u will find it on google it destroyed my marriage in the end and destroyed my life for a long time. The first time I realised I was being investigated was when officers turned up at my door to arrest me I had claimed as a single parent (which for the most part I was) I had marriage problems and seperated from my husband for months at a time as he had severe depression I paid his mother child care sometimes she wouldn't take it but for the most part she did in the end they charged me with 47k in wtc fraud this went on for years I lost my job was told I stood a good chance going t prison for 3 years and I seperated from my husband for good I had never been in trouble my whole life had a mortgage never claimed housing benefit I ended up having t agree t plead guilty t 2 counts of fraud of 20k and agree t take a cheque of 20k to court on the day of my trial I was handcuffed and put in cells and my lawyer handed over the cheque t the revenue that day at court the judge wasn't so nice and she left the court room t make a decision on my liberty she came back and said as I had paid the 20k she would spare me a prison sentence however I was tagged for a year had t be confined in my home until 8am and from 8pm for a year I also had to attend weekly meetings with a tag officer my life was hell it effected my kids life's I was in all the papers and I ended up loosing my home every job I went for I lost or didn't get because I was now classed a criminal and had a record this was years ago I never have never will get over it even now calling the tax credit office I have t deal with a seperate dept everything I claim gets checked by compliance i feel I made a mistake I did my time I paid back the money but I will never escape from it all I can say is from someone who has been thru it just always keep your records and any change tell them within ur allocated 4 weeks as advised on the hmrc web site I wouldn't put my worst enemy thru what I went thru ! Hope this helps x
