INPS voluntary contributions: what they cost and when they make sense

What they are and who can pay them

Voluntary contributions let you pay INPS for periods when you are not working, and have them count towards your right to a pension and its amount. For private-sector employees there are two conditions:

• a minimum of contributions already paid: at least five years (260 weeks) at any point in your life, or at least three years in the five before you apply;
• the employment must have ended or been interrupted. INPS allows exceptions for some suspensions, such as leave or time off provided by law or by contract, and for part-time work.

Once granted, the authorisation never lapses: you can stop paying and restart later without a new application.

What they cost in 2026

For employees the contribution is based on average pay over the last 52 weeks of compulsory contributions, with a minimum weekly value. The 2026 amounts were updated by INPS in circular no. 27 of 11 March 2026.

The 33% rate applies if you are authorised after 31 December 1995; 27.87% if you were authorised by that date. These are minimums: if your recent pay was higher, you pay more.

Craftspeople, shopkeepers and members of the Gestione Separata have their own rules and amounts, based on income over recent years: for them, look at the INPS tables in the circular.

An example with numbers

Say gross pay of €30,000 a year, about €577 a week. The voluntary contribution is 33% of that:

• about €190 a week, or about €9,900 for a full year;
• about €825 a month, paid quarterly.

This is an estimate: INPS uses your actual pay and the table brackets, so the real figure can differ somewhat.

Tax deductibility: the real cost is lower

Voluntary contributions, for yourself and for dependent family members, are deductible from income on your tax return. The saving depends on your IRPEF rate:

The benefit only exists if you have income to deduct it from: if you have stopped working and have no other income, the deduction is worth little or nothing.

When it may make sense

• You are a few months or years short of a contribution requirement, such as the 20 years for the old-age pension or the 42 years and 11 months for the standard early pension for men from 2027. I cover these in pension with 20 years of contributions and retirement age in 2027 and 2028.
• You want to avoid a gap between the end of work and your pension, and every extra year raises the amount.
• You already have an exit plan and want to know what stopping early costs: see how much pension you lose.

How to pay

You apply to INPS online. Once approved, you pay by calendar quarter, by the end of the following quarter (the first quarter by 30 June). Payments made after the deadline are void and refundable: they cannot be applied to the period afterwards. How much to pay and for which period is your call; it is best made with an up-to-date contribution statement in hand. For the overall picture, start with when can I retire.
