Plans for U.S. Tax Reform and its Consequences for German Companies

Plans from the Republican-dominated U.S. House of Representatives provide for a sweeping reform of corporate taxation in the United States. Under the new U.S. President Donald Trump the proposal could become a reality.

A com­pany’s taxable pro­fit would then be cal­cu­la­ted using a straight cash flow sta­te­ment. The cor­po­rate income tax rate is set to fall from 35% to 20%. Com­bi­ned with export sub­si­dies for U.S. com­pa­nies with simul­ta­neous taxa­tion of imports, the reform obviously aims to help reduce the Uni­ted Sta­tes’ for­eign trade defi­cit. The Uni­ted Sta­tes’ plans could have serious con­se­qu­en­ces for Ger­man com­pa­nies.

Taxa­tion of the cash flow means that the com­pany’s taxable pro­fit is cal­cu­la­ted as the dif­fe­rence bet­ween income and expen­di­tu­re—in­de­pen­dent of the car­rying amo­unts and dep­re­cia­tion or amor­tiza­tion of the assets.


If a U.S. com­pany purcha­ses a machine worth USD 100,000, the com­pany can deduct the full expen­di­ture of USD 100,000 from its “cash flow” tax in the busi­ness year in which the acqui­si­tion was made rather than wri­ting down the expense over a num­ber of years.

This con­cept is simi­lar to the imme­diate write-off of low-value assets that is well known in Ger­man tax law, but wit­hout any cap on the amo­unt. The “cash flow” tax would result in sig­ni­fi­cant liqui­dity and inte­rest rate advan­ta­ges for U.S. com­pa­nies. The plan­ned reduc­tion of the tax rate would furt­her ease the bur­den on these enter­pri­ses.

For Ger­man com­pa­nies with busi­ness rela­ti­onships in the Uni­ted Sta­tes, the pic­ture is less rosy. Ano­ther core ele­ment of the draft refor­m—the bor­der tax adjust­men­t—has poten­tially serious rami­fi­ca­ti­ons. Exports of tan­gi­ble and int­an­gi­ble pro­ducts and ser­vices are expec­ted to be exempt from the new U.S. tax. At the same time, pro­duc­tion costs incur­red for these exports can con­ti­nue to be deduc­ted wit­hout res­tric­tion. Con­ver­sely, it is expec­ted that cor­res­pon­ding imports into the Uni­ted Sta­tes will be taxed in full. The draft does not yet con­tain details of how this will be put into practice, howe­ver. In the case of imports to U.S. com­pa­nies, it is ulti­ma­tely likely that the tax deduc­tion will sim­ply be with­held by the U.S. com­pany.

If a U.S. com­pany imports a machine pro­du­ced in Ger­many cos­ting USD 100,000, the U.S. com­pany can­not claim a tax deduc­tion (eit­her imme­dia­tely or through a write-down). Howe­ver, if the com­pany buys a machine pro­du­ced in the Uni­ted Sta­tes, it can deduct the full amo­unt imme­dia­tely, which effec­ti­vely leads to tax relief of 20% in the busi­ness year in which the acqui­si­tion was made. The U.S. machine, which in prin­ciple costs the same amo­unt, would the­re­fore effec­ti­vely cost the U.S. com­pany just USD 80,000.

As a con­se­qu­ence, from a taxa­tion view­po­int the impor­ting Ger­man manu­fac­tu­ring com­pany is at a disad­van­tage com­pa­red with its U.S. coun­ter­part because the impor­ted item is USD 20,000 or (USD 20,000/USD 80,000 =) 25% more expen­sive from the per­spec­tive of the buyer in the U.S. This could put cor­res­pon­ding price pres­sure on impor­ted goods and, in an ext­reme case, lead to the price that can be obtai­ned from the Ger­man impor­ter’s per­spec­tive being redu­ced by the amo­unt of the U.S. tax charge (20%). This would mean that, finan­cially, the Ger­man com­pany would be sub­ject to the U.S. tax charge even though it was not requi­red to pay the U.S. tax at all.

Eco­no­mists believe, howe­ver, that the U.S. tax reform could cause the U.S. dol­lar to app­re­ciate in the medium to long term. This would mit­i­gate the effect of the discri­mi­na­tion against imports because the com­pa­nies impor­ting into the Uni­ted Sta­tes would bene­fit from a more favora­ble exchange rate. Yet unless coun­ter­mea­su­res are intro­du­ced in Ger­man taxa­tion (for example in the form of a deduc­tion of the U.S. tax charge from the Ger­man assess­ment basis), Ger­man expor­ters are likely to end up with an addi­tio­nal tax bur­den.


For groups with com­pa­nies in Ger­many and the Uni­ted Sta­tes, the U.S. tax reform would greatly inc­rease the sig­ni­fi­cance of the trans­fer pri­ces bet­ween the com­pa­nies. The bor­der tax adjust­ment would effec­ti­vely lead to inter­com­pany deli­ve­r­ies and ser­vices from the Ger­man com­pany to the U.S. com­pany being taxed in Ger­many wit­hout this resul­ting in a tax deduc­tion in the Uni­ted Sta­tes. Con­ver­sely, inter­com­pany deli­ve­r­ies and ser­vices from the U.S. com­pany to the Ger­man group com­pany would be exemp­ted from export tax in the Uni­ted Sta­tes and be tax deduc­ti­ble in Ger­many. The U.S. tax reform would thus lead to an effec­tive tax rate dif­fe­rence in the amo­unt of the Ger­man tax rate. Wit­hin the limits of the arm’s length prin­ciple, trans­fer pri­ces could be expe­di­ent here.

It is not yet pos­si­ble to pre­dict with any cer­tainty whe­ther the new pre­si­dent would actually be wil­ling to embark on such an ambi­tious tax reform and would in fact be able to push it through. Espe­cially as regards the pos­si­ble imp­le­men­ta­tion of the bor­der tax adjust­ment, there is still no detai­led infor­ma­tion available (for example about a poten­tial tax lia­bi­lity of the for­eign impor­ter). Ger­man com­pa­nies with busi­ness rela­ti­onships in the Uni­ted Sta­tes should nevert­he­less keep a close eye on the reform plans in the U.S.—mainly because of their far-rea­ching con­se­qu­en­ces. Parti­cu­larly when con­clu­ding lon­ger-term (sup­ply) agree­ments, they would be well advi­sed to already take into con­s­i­de­ra­tion the pos­si­bi­lity that a bor­der tax adjust­ment may be intro­du­ced (for example by wri­ting opti­ons for extra­or­di­nary notice of ter­mi­na­tion or agree­ment to rene­go­tiate the agreed pri­ces into the con­tracts).
