Tax planning service: Model the effects of the One Big Beautiful Bill Act

Technology-driven insights that clarify how tax reform affects your business

Talk to a tax advisor

The One Big Beautiful Bill Act (OBBBA) includes a broad package of tax benefits and revenue raisers that affect virtually every business in America. The tax provisions are complex and interconnected, which can jeopardize your business’s ability to take full advantage of tax benefits and corresponding business opportunities.

C-suite leaders are commonly asking the following questions about OBBBA tax changes:

How will they affect our tax liabilities and cash flow?
How could they shape our capital budgeting decisions?
What do they mean for our entity structure?
How might they affect our global structure and operations?
What do we need to consider in making estimated tax payments?

Our OBBBA tax modeling service helps clarify how these tax changes affect your tax profile and cash flow, enabling you to make strategic decisions.

OBBBA tax planning and modeling with RSM

Using our proprietary OBBBA calculator, we model the tax impact of key provisions—bonus depreciation, qualified production property, interest expense, research costs and international reforms—across one- or two-year horizons. The calculator provides:

Side-by-side comparisons of old law vs. new law
Entity-level modeling for C corporations and pass-through entities
Visual outputs that highlight where value is created or lost
Optionality to adjust inputs in real time

That data guides your discussions with our advisors about strategic elections, loss utilization and tax exposure. Whether you're evaluating capital expenditures, research initiatives, debt financing, global operations or other critical areas, the data helps you align tax planning with your business goals.

This modeling is not just about numbers—it’s about enabling smarter decisions.
