What the CRA is trying to assess is the direct tax assessment, the actual audit result, in the here and now, so the entry that we would post to the taxpayer account.
Certainly with businesses it's a little more complex than that, though. They have loss carry-forwards and other pools that are multi-year in nature. The tax earned by audit tries to abstract the predicted value of that to give us a sense of the economic impact of that audit. We use that number to tell us whether our audits are being efficient. It is a fairly good efficiency indicator, but we also try to complement it with effectiveness indicators.
We talked about practices that have disappeared. Earlier in my remarks I talked about the gifting tax shelter. Gifting tax shelters were a phenomenon in Canada, with a large number of participants. A lot of parties and stakeholders put a lot of effort in. Basically the practice has wound down. We now have 95% fewer participants. We went from roughly 50,000 participants to 2,500 participants in those gifting tax shelters. That reduction in the participation would be, to us, more of an effectiveness indicator.
Our TEBA results have been trending upwards, up into the $10-billion range per year. As an organization that tells us we're being more efficient. But we're also working hard to develop other indicators, because at some point we'd like TEBA to go down. That would tell us that we're being strategically successful.
We have recently implemented something called the liaison officer initiative. We took 120 auditors and said, “Look, we don't want you to do audits anymore. We want you to go out to businesses and talk to them about common mistakes and errors. Schedule appointments with taxpayers and help them to get it right from the start.”
We've done some control groups, and we will do statistical sampling. We'll follow the people we visited in the control groups and we'll make sure there was a tax lift from those visits. We'll assess that. We'll do the math.
It is that kind of measurement we are trying to do at a strategic level. We're very happy, at an efficiency and tactical level, when TEBA goes up. In aggressive tax planning, for example, we went from $1.2 billion in fiscal year 2012-13 to $1.7 billion in fiscal year 2013-14. It went up by $0.5 billion. That's an operational success. But strategically, five or six years from now, I'd like to be before this committee telling you that it's actually gone down because we've stamped out the practices.
