If the tax man is after someone for unpaid tax (quite a large sum) would they check out any info they receive about this person? And would they follow it up?
probably, but as you are being so unspecific i don't know. If they recieved info they wore green knickers on a friday, i doubt they'd be interested, or check it out. However, if you catch someone looking up your skirt on a friday, who knows
If this is your problem, you should see an accountant, as there is far too little information here, and you can only get reliable advice if you disclose the full story.
If you're thinking of giving information about someone, be very careful.
I know the tax man was looking for this person as they were knocking on my door a few years ago. I know the tax man is still looking for this person as they've been knocking on my visitors door recently (not sure how recent)
