FAQ

What is Section 174?

Section 174 of the U.S. Internal Revenue Code governs the tax treatment of research and experimental (R&E) expenditures. Recent changes require businesses to amortize these costs over 5 years for domestic expenses and 15 years for foreign expenses, rather than deducting them immediately.

Who should use this calculator?

Software developers, startup founders, and financial professionals who need a quick estimate of their R&D tax deductions under Section 174. It's especially useful for planning and budgeting.

How does the calculator determine the amortization schedule?

It uses the total expenses, expense type, start year, and amortization period you provide to calculate the annual amortization amount and the resulting tax deduction for each year.

Can I use this for foreign R&D expenses?

Yes. Simply select 'foreign' as the expense type, and the calculator will apply the default 15-year amortization period (or you can customize it).

Is this calculator accurate for tax filing?

This tool provides estimates for planning purposes only. For official tax filing, consult a qualified tax professional to ensure compliance with all applicable regulations.
