How a Virginia paycheck works
Virginia runs a short graduated schedule whose top rate starts at a low income level, which means most full-time employees reach the top rate quickly and the state tax behaves almost like a flat rate above that point. Withholding follows a published formula: annualise the wage, subtract a fixed standard deduction plus an amount for each exemption claimed on Form VA-4, apply the four-band schedule, and divide back down to the pay period.
Federal income tax withholding
Federal withholding annualises the wage, subtracts the standard deduction for the filing status on Form W-4 Step 1, applies the graduated schedule for that status, and deducts the dependent credit from Step 3. This page models a W-4 with Steps 2 and 4 blank: one job, no spouse income, no other income, no extra withholding. Past the income limit for the status the dependent credit tapers by a set amount for every thousand dollars of excess instead of stopping at a cliff.
Social Security and Medicare
Social Security takes a flat rate on wages up to an annual ceiling that moves with national wage growth, so it stops partway through the year for a high earner. Medicare applies to every dollar, and above a fixed threshold the employer withholds the Additional Medicare tax on the excess, unmatched by the employer and unaffected by filing status.
The Virginia formula and Form VA-4
The state standard deduction used in withholding is a single figure that does not vary with filing status, which is unusual: a married employee and a single employee on the same salary and the same number of exemptions are withheld identically. What does vary is the exemption count. Form VA-4 has a personal exemption worksheet covering yourself, a spouse who does not claim their own, and dependants, and each of those is worth a fixed amount off the annual wage. A second, smaller exemption is available for being 65 or over and for blindness, and it can be claimed for both an employee and a qualifying spouse.
The rate schedule itself is compressed. The lowest bands cover only the first few thousand dollars of taxable income, so the marginal rate for an ordinary salary is the top one, and the withholding rises in a near-straight line above that point.
Local income tax
No Virginia city or county taxes wages. Northern Virginia commuters into the District of Columbia are not taxed by DC either, because Virginia and the District have a reciprocity agreement: a Virginia resident working in DC is withheld for Virginia only. Employees who live in Maryland or the District and work in Virginia are covered by the same set of agreements in reverse.
What the employer pays on top
The employer matches Social Security and Medicare and pays federal unemployment tax at its net rate. Virginia unemployment insurance is an employer contribution at an experience-rated percentage on a state wage base, so it is not shown. Virginia takes no unemployment or disability contribution from employees.
What this calculator assumes
The figure models a salaried employee paid evenly across the year with a standard Form W-4 and state certificate, and no pre-tax deductions. It leaves out:
- Pre-tax contributions such as a 401(k), health premiums, HSA or flexible spending accounts.
- Extra withholding requested on the federal or state certificate, and the W-4 Step 2 and Step 4 adjustments.
- Bonuses and other supplemental wages, which may be withheld at a flat supplemental rate.
- Employer-side state unemployment insurance, which is priced per employer, and any federal unemployment credit reduction.
- Employees outside the normal Social Security system, such as some public-sector staff and certain visa holders.
Withholding versus your final tax bill
Withholding is a prepayment. The federal and state returns replace these standard assumptions with your real situation: itemised deductions, other income, and credits payroll knows nothing about. One job usually produces a refund; two jobs, a working spouse or investment income often produce a balance due.
