Understanding Your Hawaii Paycheck

Navigating your paycheck can sometimes feel complex, especially with various federal and state deductions. This Hawaii Paycheck Calculator helps you estimate your take-home pay by factoring in key taxes and contributions specific to the Aloha State.

Federal Income Tax

Federal income tax is a progressive tax, meaning higher earners pay a larger percentage of their income. The amount withheld from your paycheck depends on your gross income, filing status (Single, Married Filing Jointly, Head of Household), and any pre-tax deductions. This calculator uses the standard deduction and 2024 federal tax brackets to estimate your annual federal tax liability, which is then prorated per pay period.

FICA Taxes (Social Security & Medicare)

FICA stands for the Federal Insurance Contributions Act, which funds Social Security and Medicare. These are mandatory payroll taxes:

Social Security: Employees contribute 6.2% of their earnings up to an annual wage base limit ($168,600 for 2024).
Medicare: Employees contribute 1.45% of all their earnings, with no wage base limit.

Your employer also pays a matching amount for both Social Security and Medicare.

Hawaii State Income Tax

Hawaii has its own progressive income tax system. The amount of state tax withheld depends on your gross income, filing status, and the number of exemptions you claim. Each exemption reduces your taxable income by a fixed amount ($1,144 for 2024). The calculator applies the 2024 Hawaii state tax brackets to your estimated annual taxable income to determine your state tax liability.

Hawaii Temporary Disability Insurance (TDI)

Hawaii is one of a few states that requires employers to provide Temporary Disability Insurance (TDI) to employees. This insurance provides partial wage replacement if you become temporarily disabled due due to a non-work-related injury or illness. Employees can contribute a small portion towards the premium. For 2024, the employee contribution is capped at 0.5% of weekly wages, up to a maximum of $6.04 per week. This calculator includes this mandatory employee contribution.

Pre-Tax Deductions

Pre-tax deductions, such as contributions to a 401(k) or health insurance premiums, reduce your taxable income for federal and often state income taxes. This means you pay less tax on the money you contribute to these plans, effectively lowering your overall tax burden.

How the Calculator Works

This calculator takes your gross pay per period, pay frequency, filing statuses, and any pre-tax deductions to estimate your annual income. It then applies the relevant 2024 federal and Hawaii state tax laws, including FICA and TDI, to determine your estimated net pay per period. Please note that this is an estimate and actual withholdings may vary based on specific employer plans, additional deductions, or changes in tax laws.

Example Calculation:

Let's consider an example for a single individual in Hawaii:

Gross Pay per Pay Period: $2,000 (Bi-Weekly)
Pay Frequency: Bi-Weekly (26 pay periods per year)
Federal Filing Status: Single
Hawaii Filing Status: Single
Hawaii Exemptions: 1
Pre-Tax Deductions per Pay Period: $100

Step 1: Annual Gross Pay & Pre-Tax Deductions

Annual Gross Pay = $2,000 * 26 = $52,000

Annual Pre-Tax Deductions = $100 * 26 = $2,600

Step 2: Federal Income Tax

Federal Standard Deduction (Single) = $14,600

Federal Taxable Income = $52,000 (Gross) – $2,600 (Pre-Tax) – $14,600 (Std. Ded.) = $34,800

Applying 2024 Single Federal Brackets:

10% on $11,600 = $1,160
12% on ($34,800 – $11,600) = 12% on $23,200 = $2,784
Total Annual Federal Tax = $1,160 + $2,784 = $3,944
Federal Tax per Pay Period = $3,944 / 26 = $151.69

Step 3: FICA Taxes

Social Security (6.2% of $52,000) = $3,224

Medicare (1.45% of $52,000) = $754

Total Annual FICA = $3,224 + $754 = $3,978

FICA per Pay Period = $3,978 / 26 = $152.99

Step 4: Hawaii State Income Tax

Hawaii Exemption Amount (1 exemption) = 1 * $1,144 = $1,144

Hawaii Taxable Income = $52,000 (Gross) – $2,600 (Pre-Tax) – $1,144 (Exemption) = $48,256

Applying 2024 Single Hawaii Brackets:

1.4% on $2,400 = $33.60
3.2% on $2,400 = $76.80
5.5% on $4,800 = $264.00
6.4% on $4,800 = $307.20
6.8% on $4,800 = $326.40
7.2% on $4,800 = $345.60
7.6% on $12,000 = $912.00
7.9% on ($48,256 – $36,000) = 7.9% on $12,256 = $968.22
Total Annual Hawaii Tax = $33.60 + $76.80 + $264.00 + $307.20 + $326.40 + $345.60 + $912.00 + $968.22 = $3,233.82
Hawaii State Tax per Pay Period = $3,233.82 / 26 = $124.38

Step 5: Hawaii Temporary Disability Insurance (TDI)

Weekly Gross Pay = $52,000 / 52 = $1,000

TDI Contribution = 0.5% of $1,000 = $5.00 (This is less than the $6.04 weekly cap)

Annual TDI = $5.00 * 52 = $260

TDI per Pay Period = $260 / 26 = $10.00

Step 6: Net Pay per Pay Period

Gross Pay: $2,000.00

Pre-Tax Deductions: -$100.00

Federal Tax: -$151.69

FICA Tax: -$152.99

Hawaii State Tax: -$124.38

Hawaii TDI: -$10.00

Estimated Net Pay: $2,000 – $100 – $151.69 – $152.99 – $124.38 – $10 = $1,460.94
