Code of Federal Regulations Title 41. Public Contracts and Property Management § 41.302–17.46 What does my agency do if a state treats an expense as taxable even though it is nontaxable under the Federal IRC?

If one or more of the states where you have incurred tax liability for relocation expenses treats one or more relocation expenses as taxable, even though it (they) are nontaxable under Federal tax rules, you may be required to pay additional state income tax when you file tax returns with those states. In this case, your agency calculates a state gross-up to cover the additional tax liability resulting from the covered relocation expense reimbursement(s) that are nontaxable under Federal, but not state tax rules. Your agency calculates the state gross-up and then adds that amount to your RITA. Your agency will use this formula to calculate the state gross-up:

F = Federal Marginal Tax Rate

S = State Marginal Tax Rate

C = CMTR

N = Dollar amount of covered relocation expenses that are nontaxable under Federal tax rules but are taxable under state tax rules

All information, except “N,” can be found in previous calculations (if moving to, from, or within Puerto Rico, follow the rules in 302–17.44 to determine when to substitute “P” for “F”).

“N” is determined as follows:

Note to § 302–17.46:  This calculation is the same, regardless of whether your agency has chosen to use the one-year or two-year RITA process.
