Arizona Taxes: What You Need to Know

 Arizona follows federal guidelines when it comes to tax withholding, but it also has its own state tax withholding requirements. 

Arizona Federal Tax Withholding (Arizona Residents) 

For federal tax withholding, employers use IRS Form W-4 to determine how much federal income tax to withhold from an employee’s paycheck. This is based on factors such as: 

– Marital status 

– Number of dependents 

– Additional withholding amounts specified by the employee 

– Other factors like multiple jobs or deductions 

 Arizona State Tax Withholding 

For state income tax, Arizona requires employees to complete Arizona Form A-4, which determines how much state tax should be withheld from their paycheck. Arizona does not follow the federal W-4 form for state tax purposes. 

Here are some details about Arizona Income Tax Withholding: 

1. New employees must complete Form A-4 within 5 days of starting work.
2. This form determines the amount of Arizona income tax withheld from paychecks.
3. If an employee doesn’t submit Form A-4 within 5 days, the employer must withhold at a 2.0% rate.
4. Employees can request additional withholding on Form A-4.
5. To change withholding amounts, employees can submit a new Form A-4 at any time.
6. Employees should keep a copy of their completed A-4 for personal records.

This system allows Arizona employees to control their state tax withholding, with a default rate in place to ensure compliance if paperwork isn’t completed promptly. 

FICA & State Insurance Taxes 

FICA, or the Federal Insurance Contributions Act, is like a  savings plan for your future. It’s made up of two parts: Social Security and Medicare. Let’s break it down: 

Social Security (6.2%): This is your contribution to the retirement and disability fund. Think of it as paying it forward – you’re supporting current retirees while building your own safety net. The catch? It only applies to a certain amount of your income each year. In 2024, that limit is $168,600. Earn more than that? Congrats! Your Social Security deductions stop after hitting this ceiling. 

Medicare (1.45%): This part funds our national health insurance program for seniors and some disabled individuals. Unlike its Social Security sibling, Medicare tax knows no limits. It’ll take its 1.45% cut from every dollar you earn, whether you make $30,000 or $3 million. 

Together, these taxes add up to 7.65% of your paycheck. But here’s the kicker – your employer matches this amount, effectively doubling the contribution. Self-employed? Sorry, you’re on the hook for both halves. 

Pre-Tax deductions in Arizona  

Standard and Itemized Deductions:

   Arizona follows federal guidelines for most pre-tax deductions, which can significantly reduce your taxable income. Here’s a rundown of common pre-tax deductions available to Arizona employees: 

Health Benefits:  

• Employer-sponsored health, dental, and vision insurance premiums 

• Health Savings Account (HSA) contributions (with qualifying high-deductible plans) 

• Flexible Spending Account (FSA) contributions for medical expenses 

Retirement Savings:  

• 401(k), 403(b), and 457 plan contributions 

• Traditional IRA contributions (in certain cases) 

Family-Related:  

• Dependent Care Assistance Program (DCAP) contributions 

• Group-term life insurance premiums (up to $50,000 coverage) 

Work-Related:  

• Commuter benefits and parking reimbursements (if offered by employer) 

These deductions lower both federal and Arizona state taxable income, potentially reducing your overall tax liability. While Arizona doesn’t offer unique state-specific pre-tax deductions, it generally aligns with federal rules. 

Remember, the impact of these deductions can vary based on individual circumstances. For personalized advice, consult a tax professional or payroll advisor.  

Dependent Credit (replacing exemption from 2019):

   – $100 credit for dependents under 17 

   – $25 credit for all other dependents 

   – Subject to income-based phase-out 

   – Provide full details (name, SSN, relationship, months in home) on appropriate forms to claim 

Other Exemptions:

• a) Blindness: Available for taxpayer or spouse
• b) Age 65 or older: Available for taxpayer or spouse
• c) Non-dependent persons 65 or older:

      – If taxpayer paid over 1/4 of nursing care costs (>$800) in Arizona institutions 

      – Or if taxpayer paid over $800 for home health care or medical costs

      – Must be Arizona resident 

      – Lived in principal residence all year 

      – Taxpayer paid over half of support
