Ten principles of sound tax policy
The Tax Foundation’s Ten principles of sound tax policy are a must-read for those influencing tax policy. I think the list can be further refined down to about half that, but maybe they wanted to get an even ten.
For instance, maintaining the neutrality of the system (#2) will result in broad bases (#3). It’s when the system gets less neutral (i.e. favours certain groups or behaviours) that the base is narrowed. Various special interest deductions put in place to encourage desirable behaviour or punish undesirable behaviour have narrowed the base and caused rates to be kept high unnecessarily.
Harmonization of federal, state/province and local/municipal taxes (#10) is part and parcel with creating a simple tax system (#4). The provincial government has been criticized recently about its reluctance to harmonize Ontario’s sales tax with the Federal GST. The premier’s misguided reasoning for the reluctance? It would place a tax on certain exempt items, thus eliminating some of the complexity and non-neutrality in the tax.
Tax stability (#5) is important because it makes them predictable, which is also aided when there is no retroactivity (#6). When politicians can make changes to taxes retroactive, tax is not predictable. The Canadian government announced recently the retroactive increase in the Basic Personal tax credit. You’re unlikely to hear anyone complain about this, but nonetheless it isn’t ideal tax policy.
Transparency (#1) is important no matter what government initiative we’re talking about, and an open process (#9) is one manifestation of this requirement. All the workings of a democratic government must be open to its citizens and open to criticism and debate. Tax is no different from anything else in this respect.
So I humbly put forward my own principles of sound tax policy: simplicity, neutrality, transparency, and predictability. I think that basically covers it at a more abstract level than the Tax Foundation’s ten.
