New Bill, New Credits — Maximize Them Now
The Big Beautiful Bill allows for immediate expensing of domestic R&D costs on a permanent basis. Certain small businesses (under $31mil) are allowed to retroactively apply the rules back to 2022, restoring deductions that were delayed under the TCJA amortization regime.
The only caveat? Businesses have a year to take advantage of this.
Move now to claim these valuable tax credits before others do and keep your business ahead.

We have been working with RK Partners for a few years now on the R&D Tax Credits, having worked with another specialist provider before. One thing that stood out is RK’s knowledge of the agricultural space: they understand the work that we do and are clearly experts in the sector.
The result is that we have had a more substantial benefit year on year, which has been very helpful! They have also been great at working with our CPA throughout the process – saves us time, for sure! I would recommend the team at RK to anyone in the poultry sector looking to do an R&D Tax Credit claim!
