超過利益課税への静かな変質

2017年12月の米国トランプ税制(TCJA)は、設備に対する資本的支出を、耐用年数に応じた減価償却に代えて、取得時全額控除(full expensing)にした。このことは、日本でも知られている(増井良啓・租税法入門第2版254頁など)。

今回、英国のSpring Budget 2023に接し、英国もその方向に踏み出すようである(hat tip: @masayoshimu)。以下、HM Treasuryのメディア用ファクトシートからコピペする。

Full Expensing (FE)

  • This lets taxpayers deduct 100% of the cost of certain plant and machinery from their profits before tax. It is effective from 1 April 2023 to 31 March 2026.
  • It applies to spending on main rate equipment, which includes but is not limited to, warehousing equipment such as forklift trucks, tools such as ladders and drills, construction equipment such as bulldozers and excavators, machines such as computers and printers, vehicles such as tractors, lorries and vans, office equipment such as chairs and desks, and some fixtures such as kitchen and bathroom fittings and fire alarm systems.
  • FE means that companies can deduct 100% of the cost from their profits straight away – rather than more slowly over the life of the asset.
  • Similar to the super-deduction, FE also results in a 25p tax saving for every £1 invested (19% x 130% super-deduction rate = 25%).
  • Before the super-deduction and with the 19% Corporation Tax rate, companies investing £10m in main rate assets received a £342,000 tax saving in year 1. Under full expensing, on a £10m investment, a company will receive a £2.5 million tax saving in year 1.
  • As part of his commitment to maintain a stable economy, the Chancellor’s long-term ambition is to make full expensing permanent.

米国TCJAは税率を35%から21%に引き下げたのに対し、今回の英国のこの話は法人税率を19%から25%に引き上げることとセット。Devereux教授のこのコメントは、「1983年のLawson改革を転換するもの」と評している。

取得時全額控除は、有形設備から生ずる通常利益に課税を及ぼさず、残りの超過利益に課税することを意味する。法人所得税の課税ベースを超過利益にしていく方向で、静かに変質がはじまっているのかもしれない。

なお、国際的な租税競争との関係では、Pillar TwoのGloBEで、SBIE(Substance-based Income Exclusion、実体に基づく所得のカーブアウト)が認められている。つまり、国別実効税率の計算上SBIEがあることで、給与と、有形固定資産の帳簿価額の5%(経過措置後)については、トップアップ課税の対象から外れる。逆に言えば、軽課税国としては、(とりあえずQDMTTは入れるとしても)、一般の法人税について有形設備がらみで租税競争を続行し、加速償却などで企業誘致を図ることは特段妨げられない。その結果が「通常利益への実効税率ゼロ」になるかどうかは今後の動向を見ないとわからないけれど、どうやらGloBEルールが上記の変質への歯止めにはならないといえそう。
