The short answer
- Back pay (also called retroactive pay or past-due benefits) covers the months between your effective date and the start of your regular payments.
- Payments generally start the first day of the month after the effective date.
- Each month is paid at the rate in effect that month, so cost-of-living increases are included.
- VA back pay isn't taxable, and it usually arrives as one lump sum after the decision.
What VA back pay is
When VA grants a claim, it doesn't pay only from the decision date forward. It pays from the effective date, which is often months earlier. The money owed for that stretch is back pay. VA calls it "past-due benefits" in decision letters and fee agreements.
How VA sets your effective date
The effective date depends on the kind of claim. These are the most common rules from VA's effective date page and 38 CFR § 3.400:
| Situation | Usual effective date |
|---|---|
| New claim filed within one year of leaving active duty | As early as the day after separation |
| New claim filed more than a year after separation | The later of the date VA got the claim or the date the condition arose |
| Intent to File submitted, full claim filed within one year | The Intent to File date can be treated as the claim date |
| Increase in a rated condition | The earliest date the evidence shows the increase, if VA gets the claim within one year of it. Otherwise the claim date. |
| Review requested within one year of a decision (continuous pursuit) | Can preserve the original claim's effective date |
| Liberalizing law, such as the PACT Act | Special rules. Can reach back to the law change if you file within a year of it. |
| Clear and unmistakable error in an old decision | The date benefits would have started without the error |
How the math works
VA pays from the first day of the month after the effective date (38 CFR § 3.31). Then it adds up each month at the rate for your rating and dependents in effect that month. Rates usually change every December 1 with the cost-of-living adjustment.
Example 1: a new claim
A veteran with no dependents files an Intent to File on February 15, 2026. VA grants 50% with that effective date and decides the claim in late October 2026. Payments start March 1, 2026. March through October is 8 months. Using the 2026 rate for 50% (veteran alone, effective December 1, 2025), the math is:
8 × $1,132.90 = $9,063.20 in back pay, before any fees or offsets.
Example 2: an increase
Same veteran, but they were already rated 30% for those months and VA increased them to 50%. VA pays only the difference: $1,132.90 − $552.47 = $580.43 a month. Over 8 months that's $4,643.44.
Look up your own numbers with our VA rating calculator, which uses VA's full 2026 tables including dependents.
Example 3: an older effective date
If your effective date reaches back into earlier years, VA uses each year's rate for those months. For example, months before December 1, 2025 are paid at the earlier rates. That's why back pay calculators that multiply today's rate by every month can overstate the total. Our back pay calculator gives a quick estimate and flags this limit.

What can reduce back pay
- Military retired pay. If you're rated under 50%, VA disability generally offsets retired pay dollar for dollar unless you qualify for CRSC. At 50% or more, Concurrent Retirement and Disability Pay (CRDP) usually lets you receive both. DFAS adjusts retired pay after a retroactive award.
- Separation, severance, or disability severance pay. VA may recoup it from compensation, with exceptions for some combat-related severance.
- Drill pay for Reserve and Guard members for the same days.
- Incarceration over 60 days for a felony limits payments.
- Representative fees. If you signed a fee agreement for work after VA's first decision, VA can withhold the fee from past-due benefits and pay it directly. Our fee is 20% of past-due benefits, only if we win. Using Example 2, 20% of $4,643.44 would be $928.69. No fee is charged on monthly payments going forward.
When back pay arrives
Back pay usually comes by direct deposit as a single lump sum after the decision. Timing varies. Many veterans see it within a few weeks, but extra steps, such as a DFAS retired-pay audit, a fee withholding, or a recoupment, can take longer. Your decision letter will show the payment start date. If a deposit hasn't arrived after about 30 days, call VA at 800-827-1000.
Back pay for dependents
At 30% or more, you can be paid extra for a spouse, children, and dependent parents. If you add a dependent late, the extra amount generally goes back to the event date (like a marriage or birth) only if VA gets the information within a year of it. Otherwise it starts from when VA receives it. Add dependents promptly through VA.gov.
Is back pay taxable?
No. VA disability compensation, including back pay, is not taxable income. If a retroactive award reduces military retired pay you already paid taxes on, you may be able to amend prior returns. See Is VA disability taxable?
How to protect your back pay
- File an Intent to File the moment you decide to claim.
- File within a year of separation if you can.
- After a decision, request a review within one year to keep continuous pursuit.
- Check every effective date on your decision letter.
- Keep proof of when you filed anything with VA.
