@FundamentAli;
Since you do VAT returns monthly, you need to download KRA's Taxpayer Software. It allows you to do enter the details off-line and then upload only once at the end of the month.
Apart from VAT, the software also handles all other taxes, including the annual income tax return.
If you photocopied last year's form and changed the date, it will most likely be rejected. Each year, KRA produces a new version of the form to take account of any changes in taxation laws. These are posted in their website.
I once tried filling the form for the wrong year and was advised against it by a KRA official. They had misplaced my 2005 return. I went to follow-up in 2007 and it couldn't be found. So they told me to re-do it. I asked for the form and was sent to "archives" to collect the "old" form. I was told that one cannot use the form for the wrong year.
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
