Bonus inputs

Use gross-to-net for a planned bonus or net-to-gross when a take-home amount was promised. This tool is limited to one-time or nonperiodic taxable cash bonuses; use a full paycheck calculation for regular or periodic wages, commissions, and overtime.

Gross bonus amount Enter the taxable bonus to be paid.

Federal withholding method

Payment presentation Federal and Arkansas treatment are tested separately. DFA expressly directs 3.7% when a bonus is paid at the same time as regular wages. For a separately paid bonus, use the manual Arkansas review path or confirm the current treatment with DFA or the payroll provider.

Regular wages had federal income tax withheld

The optional 22% federal flat method generally depends on regular wages having had income tax withheld in the current or prior year.

Pay frequency

YTD Social Security wages from this employer Used only for the 2026 $184,500 Social Security wage-base check.

Arkansas withholding settings

Arkansas withholding profile Presets are documentation prompts, not eligibility decisions. Texarkana treatment depends on residence or work location inside the city limits; military-spouse treatment requires a current signed form and supporting records.

Arkansas income-tax withholding applies

Profile presets update this control. Clear it only when the employer has support for an Arkansas withholding exception.

Arkansas bonus withholding method The current DFA employer instructions expressly say to deduct 3.7% when bonuses, commissions, or overtime wages are paid at the same time as regular wages. They do not publish a separate bonus-payment formula in that paragraph.

Manual Arkansas base withholding Used only for Manual review. Enter the state withholding amount determined from current employer instructions, DFA guidance, or the payroll system before any additional AR4EC amount below.

Arkansas-taxable bonus percentage Use 100% for fully Arkansas-taxable wages. For a nonresident working in multiple states, enter the supportable Arkansas work allocation; Arkansas does not publish a general mobile-worker day threshold here.

Additional Arkansas withholding on this bonus Optional per-paycheck amount from Form AR4EC Line 4. Apply it once only when the employee's current instruction and payroll timing call for it.

Timing matters. The revised 2026 DFA employer instructions say to deduct 3.7% of a bonus paid at the same time as regular wages and warn that this may overwithhold. Because that paragraph does not expressly prescribe treatment for a separately paid bonus, this calculator flags separate payments for review instead of inventing an aggregate or universal flat rule. AR4EC exemptions and credits do not alter the displayed 3.7% base calculation; documented exceptions can turn state withholding off.

Employer cost estimate settings

Arkansas UI employer status The 2.0% new-employer total combines the 1.8% base contribution and 0.2% administrative assessment. Assigned notices can differ.

YTD Arkansas UI wages before bonus Used only for the employer-side Arkansas unemployment estimate.

Arkansas UI wage base Arkansas DWS publishes a $7,000 taxable wage base for calendar year 2026.

Arkansas UI employer rate 2.0% is the total 2026 new-employer rate. Experienced employers should use the total rate shown on the DWS notice and should not add the 0.2% assessment a second time.

Arkansas UI-taxable bonus percentage This changes employer cost only; Arkansas UI is not deducted from employee take-home.

YTD FUTA wages before bonus

Estimated FUTA rate after credit 0.6% assumes the full state-unemployment credit. The final 2026 credit-reduction status is not determined until later in the year.

Employer UI, FUTA, and employer FICA never reduce employee net pay. Rates and wage-base treatment can vary by employer, successor status, exclusions, and the final FUTA credit.

What this calculator includes

Current 3.7% instruction

Apply DFA's revised 2026 bonus instruction only in the same-paycheck context it expressly describes, with cents-based payroll math and an overwithholding warning.

Separate-payment review

Flag a separately paid bonus and expose a manual Arkansas amount because the current instruction does not publish a separate-payment bonus formula in that paragraph.

Arkansas sourcing and exceptions

Keep nonresident allocation, Texarkana certificates, military-spouse documentation, active-duty pay, and other supported exceptions visible instead of treating every bonus as fully taxable.

Employee and employer costs separated

Test FICA caps, Additional Medicare, Arkansas UI, and FUTA with independent YTD inputs so employer taxes never reduce take-home.

Arkansas bonus withholding FAQ

Does Arkansas have a flat bonus withholding rate?

The current revised DFA instructions direct employers to deduct 3.7% when bonuses, commissions, or overtime wages are paid at the same time as regular wages. That is a withholding instruction for a stated context, not the employee's final income-tax rate or a universal rule for every payment timing.

What if the bonus is paid separately?

The current bonus paragraph does not expressly publish a separate-payment formula. The calculator therefore shows a review warning and offers a manual Arkansas withholding amount rather than silently extending the same-paycheck instruction.

Why do some earlier 2026 documents show a different rate?

Act 1 of the 2026 First Extraordinary Session reduced the top individual rate to 3.7% for tax years beginning January 1, 2026. DFA replaced its earlier 2026 employer instructions and formula with revised versions reflecting 3.7%.

Do AR4EC exemptions reduce the displayed 3.7% base?

No. The current bonus instruction applies 3.7% directly to the bonus. A documented withholding exception can turn Arkansas withholding off, and AR4EC Line 4 can add a per-paycheck amount when appropriate.

How are nonresident bonuses handled?

Arkansas generally withholds on wages for services performed in Arkansas. Use the allocation input for a supportable Arkansas share; no general mobile-worker day threshold or reciprocity shortcut is assumed.

Can Texarkana or military status create an exception?

Possibly. Texarkana certificates depend on residence or work within the city limits, the military-spouse certificate must be renewed annually, and active-duty treatment applies only to qualifying military pay. Keep the signed form and supporting records.

Does Arkansas unemployment tax reduce the bonus?

No. Arkansas UI is employer-funded. The employer-cost panel uses the 2026 $7,000 wage base and 2.0% total new-employer rate, while allowing an assigned rate or noncontributory status.

Can this calculator gross up a promised net bonus?

Yes. Net-to-gross mode solves numerically across federal supplemental-wage rules, FICA thresholds, Arkansas method eligibility, exemptions, and fixed additional withholding.
