Order counts across all children: if the eldest is 25, the youngest is still the second or third child.

Of these, older children no longer eligible

Over 18, or over 24 in full-time study; they still count for birth order.

1,400, 2,800 and 6,000 roubles — until the cap

The standard child allowance per month, the saving it produces over a year, and the month your income crosses the cap and the allowance stops.

The child allowance is not a payment; it is a slice of salary that escapes tax. A first child removes 1,400 roubles from the taxable base each month, a second 2,800, a third and each after it 6,000. A child with a disability adds a further 12,000 for parents.

It does not run all year. Once cumulative income passes 450,000 roubles the allowance stops until January. On 80,000 a month that happens in June; on 40,000 it lasts until December.

How to use

Enter the monthly salary before tax and the total number of children, including adult ones.
Enter how many of them are older children who no longer qualify, and how many are children with a disability.
Say whether the deduction is doubled — for a sole parent, or where the other parent has waived it.
Read the monthly deduction, the tax it saves and the month the annual income limit ends it.

Why the third child is worth more than the first two

The deduction is not a flat amount per child. The first and second children attract a smaller figure each, and from the third onwards the amount rises sharply. That is why the saving is not proportional: on a salary of 80,000 one child saves 182 ₽ a month, two save 546 ₽, and three save 1,326 ₽.

The deduction reduces the taxable base rather than the tax, so what lands in your pocket is 13 percent of the deduction. It also stops once cumulative income for the year passes the statutory limit, which is why the annual saving is rarely twelve times the monthly one.

Salary of 80,000 ₽ a month before tax, no children with disabilities, single rate. The annual figure stops when income passes the limit. Worked out with this calculator.

Order of birth, not order of eligibility

Children are counted in birth order regardless of whether each still qualifies. An adult first child does not drop out of the count: a younger sibling remains the second or third child and keeps the larger amount. Entering the older children in the separate field is what preserves that order.

A child with a disability carries its own amount in addition to the amount for birth order, and the two are added rather than replacing one another.

The month cumulative income reaches the cap and the allowance ends
The real saving, both monthly and across the year

What to keep in mind

Birth order includes adult children: if the eldest is 25, the youngest still counts as the third child, not the first.
A sole parent, or one parent when the other waives theirs, gets double the amounts — choose the double deduction; older children who no longer qualify still count for birth order.

FAQs

Up to what age does it apply?

Eighteen, or for a child in full-time education the period of study up to twenty-four. It runs to the end of the year in which the child turns 18 or 24, but for a student only while studying: finish in June and it stops from July (Article 218(1)(4) of the Tax Code).

Does the claim need renewing each year?

No, one application is enough unless something changes — a new child, a new employer, or a child starting or finishing full-time study.

What if my employer never applied it?

Reclaim it through an annual tax return for the last three years, attaching birth certificates and an income statement from the employer.

Do the ordinary and disability allowances stack?

Yes. A second child with a disability gives 2,800 plus 12,000, so 14,800 roubles a month.

What does the deduction save on a salary of 80,000?

182 ₽ a month for one child, 546 ₽ for two and 1,326 ₽ for three. The deduction reduces taxable income, so the cash effect is 13 percent of it.

Does an adult child stop the count?

No. Children are numbered by birth order whatever their age, so a younger sibling stays the second or third child and keeps the larger amount. Enter the grown-up children in the separate field to keep that order intact.

Worked example

Two children on a salary of 80,000

Input: 80,000 ₽ a month, 2 children

Output: 4,200 ₽ a month for 5 months, 2,730 ₽ saved over the year

Note: The 450,000 cap arrives in month six, so the allowance only applies five times. That is why it barely registers on higher salaries.
