I created my 1st account in the USA and lived there, but moved to Australia a few years later. My 1st account had USA but my second one I was honest and put AU. The thing is my credit card for sl is based in the USA and in USD. So when I went to buy Lindens, I was charged a conversion fee from GB to USD (yet I had AU listed in sl not GB???) on my credit card!!! That was not acceptable as my credit card is US and USD so I changed my location back to US to avoid this in the future. I was not even concerned about VAT because in either case it did not apply to me at the time. And my IP has not been flagged! I did contact LL about this and I do not recall the results but I do know the fix was to change my location to match my bank account and not my physical location.
