How do I start comparing two paychecks?

Compare gross and earnings rows first, then withholding and payroll programs, deductions and reimbursements, YTD values, and net pay. A larger delta is a starting point, not proof of the cause.

Can TakeHome IQ tell me the exact cause?

No. The app shows category deltas and possible changed inputs to review. Confirm the cause against the underlying stubs, elections, employer records, and current official guidance.

Does an OBBBA deduction automatically create a pay-stub change?

This page does not establish that result. A possible return deduction does not automatically create a pay-stub line or reduce current employer withholding.

Why did my paycheck change? Lines to compare

A changed net amount can reflect one changed line or several interacting changes. Compare captured values first. The largest difference may be an effect of another input, so it does not by itself prove the cause.

1. Compare gross and earnings rows

Review hours, rates, overtime, premium pay, bonuses, commissions, imputed income, and other adjustments. Confirm pay-period dates and whether a line was paid with regular wages or separately. A changed earnings line can also change several downstream withholding and deduction rows.

2. Compare withholding and employee programs

Review federal, Social Security, Medicare, state, local, disability, paid-leave, and other employee-program rows separately. A larger combined payment may use annualized withholding, while other payment facts may permit another method. The printed delta does not identify the legal rule without the employer's method and forms on file.

3. Compare deductions and reimbursements

Look for changed benefit elections, retirement contributions, percentage deductions, garnishments, after-tax items, and reimbursements. Federal, Social Security and Medicare, state, and local wage treatment can differ by plan, category, and jurisdiction.

4. Review forms and effective dates

A new W-4 or state certificate can affect withholding depending on wages and every field on the form. Compare effective dates, payroll settings, and whether the employer used the new information on this pay period.

5. Review program-specific YTD values

Use employer-tracked Social Security-taxable and Medicare-taxable YTD wages, not generic gross earnings. Employer grouping, job changes, deductions, and program-specific bases can change whether a threshold is reached.

6. Treat year and jurisdiction changes as possibilities

Withholding tables, premiums, benefits, local assignments, resident/work- state facts, and payroll-program rules can change. Verify which rule and effective date applies instead of assuming January or a state update is the cause.

Federal overtime return deduction boundary

The approved archive does not establish current OBBBA pay-stub reporting or paycheck-withholding treatment, and the app does not calculate an OBBBA return amount. A possible return deduction does not automatically reduce employer withholding.

What TakeHome IQ compares

For saved paychecks from the same Work Source, TakeHome IQ compares five aggregate categories: gross, federal withholding, combined state/local/ employee-program amounts, Social Security and Medicare, and deductions. It can also surface a small number of changed input drivers.

Those deltas and drivers are review aids, not a causal allocation of the entire net change. Confirm the explanation against the two stubs, saved inputs, elections, employer records, and current official guidance.
