Form 8974, quarter by quarter
Social Security first, then Medicare, then carry the rest: one hypothetical credit through three quarters, and why the filing date matters.
The credit is applied to the employer's payroll taxes in a fixed order: Social Security (6.2% of wages) first, up to $250,000 a quarter, then Medicare (1.45%). It never touches the employees' half or the income tax withheld from them, and it isn't a refundable credit: a quarter with no employer tax uses none of it.

Wrong
Filed April 14, 2028, just before the deadline: the credit starts in Q3 2028.
Right
Filed March 10, 2028: the credit starts in Q2 2028.
Same credit, same payroll. Filing a few weeks earlier moves every quarter of it forward by one: the credit runs out in Q3 2028 instead of Q4 2028.

The words this page teaches
Each links to its glossary definition, which also names the authority behind it and the components that render it.
- Form 8974The form attached to each quarterly Form 941 to apply an elected research payroll credit — first against the employer's Social Security tax, up to $250,000 a quarter, then the employer's Medicare tax — carrying what the quarter cannot absorb to the next
- Payroll liabilitiesWhat an employer owes on wages it has already paid — the income tax and the employees' share of Social Security and Medicare withheld from their pay, plus the employer's own payroll taxes — until it is deposited with the government. The withheld part was never the employer's money: IRS Pub. 15 calls it trust fund taxesConvention
- Refundable creditA tax credit whose excess over the tax due is paid out in cash. Because it does not depend on taxable income, it is generally accounted for outside ASC 740 — as a reduction of the related cost or as other incomeConvention
