Fixed Match limit

Are there any regulations limiting the amount of compensation used in a fixed match formula? We have a client wanting to do a match of 100% on the first 6% of deferrals, then 50% on the next 2% of deferrals. Thus allowing for a 7% match on 8% of compensation. 

Under IRC section 401(a)(17), compensation is limited for qualified plans.  For a calendar year 2024 plan, that limit is $345,000. For 2025 it will be $350,000.

No additional limit like the 6% for Safe Harbor Match, correct?

Correct, but you will still need to test.
