This guide accompanies the Italian TFR calculator and explains what the estimate includes, which figures to use and how to read each step.
The tool does not produce an official calculation. It reconstructs the balance from the figures entered and stops before final separate taxation.
Italian TFR calculation at a glance
- Scope
- One private-sector employment relationship with TFR held by the employer or Treasury Fund
- Two modes
- Documented accrued quota or estimate from actual remuneration for the period
- Estimated gross quota
- Actual TFR-eligible remuneration ÷ 13.5, without a second adjustment
- Revaluation
- Only on the previous balance, with separate months and FOI change
- Tax included
- Substitute tax on revaluation: 11% up to 2014 and 17% from 2015
- Tax excluded
- Final separate taxation of the TFR
Section 2
What the calculator covers and who it is for
The estimate covers one private-sector relationship and separates accrual, revaluation and taxes.
Included
Opening balance, accrued quotas, gross revaluation, substitute tax and net revaluation.
Not included
Final separate taxation, advances, supplementary pensions and Italian public-sector regimes.
Section 3
Figures and documents to prepare
Use checked figures and keep accrued quota, previous balance and revaluation data separate.
- TFR balance at the end of the year before the first period entered.
- TFR quota stated in employment documents, if available.
- Alternatively, the actual total TFR-eligible remuneration for the period.
- The pension-contribution offset actually due and deductible, if applicable.
- Number of months for which the previous balance is revalued.
- The correct cumulative FOI change for that revaluation period.
Section 4
The two quota calculation modes
Documented mode uses a quota that has already been determined; estimated mode reconstructs it from two figures.
| Mode | When to use it | Figures required |
|---|---|---|
| Documented accrued quota | A reliable document already states the TFR accrued for the period. | The accrued quota as shown in the document. |
| Estimate from remuneration | You know the actual TFR-eligible remuneration but not the quota. | TFR-eligible remuneration and exact pension-contribution offset. |
Section 5
How the accrued quota is estimated
Actual TFR-eligible remuneration for the period is divided by 13.5 and corrected by the exact pension-contribution offset.
Estimated mode
Gross quota = actual TFR-eligible remuneration for the period ÷ 13.5
Accrued quota = gross quota − actual pension-contribution offset
Eligible remuneration depends on Article 2120 and the applicable Italian collective agreement.
Unless a collective agreement provides otherwise, the base includes amounts paid non-occasionally because of the employment relationship. Equivalent remuneration may also apply to certain protected absences.
The calculator does not decide which pay items are TFR-eligible. Reconstruct the amount from the employment records.
Section 6
Partial years and the 15-day rule
For a partial period, use the actual remuneration for that period without annualising it.
No double adjustment
Quota = actual TFR-eligible remuneration for the period ÷ 13.5
Do not then apply: × months ÷ 12
- A fraction of a month lasting at least 15 days counts as a full month.
- A fraction shorter than 15 days does not count as a full month for the quota.
- This rule must already be reflected in the documented quota or the eligible remuneration entered.
Section 7
Pension-contribution offset: use the exact amount
The deduction is not a yes-or-no switch and is not always 0.50% of TFR-eligible remuneration.
- TFR base
- Remuneration determined under Article 2120 and the applicable collective agreement.
- Social-security base
- The contribution base on which the employer’s pension contribution may be due.
- Enter the pension-contribution amount actually due and deductible for the period.
- With a full exemption the offset may be zero.
- With a partial exemption only the amount actually due is relevant.
- If the amount is unknown, do not automatically assume 0.50%.
Section 8
Revaluation of the previous balance
TFR already present at the start of the year is revalued; the quota accruing in that year is not.
Rate applied by the calculator
Fixed component = 1.5% × revaluation months ÷ 12
Variable component = 75% × positive FOI change
Total rate = fixed component + variable component
If the FOI change is negative, the variable component is zero and does not reduce the balance.
Use the cumulative change in the national general FOI index excluding tobacco from the previous December to the relevant month.
For a full year the reference normally reaches December. When employment ends during the year, use the relevant month required by the rules.
Section 9
Substitute tax and separate taxation
These are different taxes, and the calculator includes only one of them.
| Item | Treatment in the calculator |
|---|---|
| Revaluations up to 2014 | 11% substitute tax on gross revaluation. |
| Revaluations from 2015 | 17% substitute tax on gross revaluation. |
| Final separate taxation | Not calculated. It depends on the applicable Italian tax rules and subsequent checks by the Italian Revenue Agency. |
Section 10
How to complete the calculator
Enter years in order and use the same accrual mode for every period.
Enter the opening balance
Use the balance at the end of the year before the first period. It may be zero if employment begins in that first period.
Choose the mode
Use the documented quota or enter TFR-eligible remuneration and the exact pension-contribution offset.
Complete revaluation data
Enter revaluation months and the cumulative FOI change separately.
Check each year
Verify the order, continuity and source of every figure before calculating.
Section 11
How to read the result
The summary separates the amount accruing in the period from the increase in the previous balance.
- Accrued quota
- The documented quota or estimated quota after the pension-contribution offset.
- Gross revaluation
- The increase calculated on the opening balance.
- Substitute tax
- Tax applied only to revaluation.
- Net revaluation
- Gross revaluation less substitute tax.
- Closing balance
- Opening balance plus accrued quota and net revaluation.
- Estimated total
- Balance before final separate taxation.
Section 12
Checkable examples
The examples distinguish the accrual of a new quota from revaluation of an existing balance.
Example 1 — Six months, estimated mode
Actual TFR-eligible remuneration: €13,500.00
Gross quota: €13,500.00 ÷ 13.5 = €1,000.00
Exact pension-contribution offset: €67.50
Accrued quota: €1,000.00 − €67.50 = €932.50
No further 6/12 adjustment applies because €13,500 is already the actual total for the period.
Example 2 — Six months of revaluation
Opening balance: €10,000.00
Cumulative FOI change: 1.20%
Rate: (1.5% × 6/12) + (75% × 1.20%) = 1.65%
Gross revaluation: €165.00
17% substitute tax: €28.05
Net revaluation: €136.95
Section 13
Excluded cases and cases requiring separate checks
Some situations require figures or rules that the calculator cannot reconstruct.
- TFR transferred wholly or partly to a supplementary pension scheme.
- TFS or TFR regimes in Italian public employment.
- Advances, assignments, attachments or amounts already paid.
- Several employment relationships combined into one statement.
- Periods before 2001.
- Disputes about eligible pay, job classification or collective agreements.
- Employer insolvency or intervention by the INPS Guarantee Fund.
- Final separate taxation and the final net amount.
Section 14
Common mistakes to avoid
The most significant errors come from confusing periods, contribution bases and revaluation.
- Do not annualise actual remuneration for a partial period.
- Do not apply months/12 after dividing the actual total by 13.5.
- Do not assume a 0.50% offset without the actual amount.
- Do not confuse months worked with revaluation months.
- Do not revalue the quota accrued in the same year.
- Do not use an inflation figure other than the required FOI change.
- Do not describe the result as the final net amount.
Section 15
Frequently asked questions
Short answers about the figures, formulas and limits of the estimate.
Is the result the net TFR amount I will receive?
No. It is the estimated balance after only the substitute tax on revaluation and before final separate taxation. It is not a forecast of the payment or the final net amount.
Which calculation mode should I choose?
Use “Documented accrued quota” when a reliable document already states the TFR accrued for the period. Use “Estimate from remuneration” when you know the actual TFR-eligible remuneration for the period and the exact pension-contribution offset, if any.
Should I annualise remuneration earned over a few months?
No. Enter the actual TFR-eligible total for the period. The calculator divides it by 13.5 and does not apply a second months-over-12 adjustment.
How does the 15-day rule work?
For TFR accrual, a fraction of a month lasting at least 15 days counts as a full month. The calculator does not reconstruct this rule from dates: the amount entered must already relate to the correctly counted period.
Can I always enter 0.50% as the pension-contribution offset?
No. Use the amount actually due and deductible for the employment relationship. The social-security base may differ from TFR-eligible remuneration, and a full or partial exemption may eliminate or reduce the offset.
Are revaluation months the same as months worked?
Not necessarily. Revaluation months concern the TFR balance that already existed at the start of the year. The quota accrued during the year follows the period data and is not revalued in that same year.
Which ISTAT figure should I use?
Use the cumulative change in the national general FOI index excluding tobacco, from the previous December to the relevant month. Do not use a standard year-on-year inflation figure unless it covers that same period.
Is the quota accrued during the year revalued immediately?
No. Article 2120 excludes the quota accrued in the current year from revaluation. The calculator revalues only the balance present at the start of the period.
What happens if the FOI change is negative?
The variable component does not reduce the TFR. The fixed 1.5% component remains and is adjusted for the revaluation months when the period is shorter than a year.
Does the calculator apply final separate taxation?
No. It applies only the substitute tax on revaluation: 11% up to 2014 and 17% from 2015. Final separate taxation of the TFR is a different step and is excluded.
Can I use it for TFR paid into a pension fund?
No. TFR transferred to supplementary pension provision becomes part of the individual pension position and follows the fund’s contributions, returns, costs and tax rules.
Can I use it for Italian public-sector employment?
Not as a definitive calculation. Italian public employment may be subject to TFS or TFR depending on the date, sector and individual position. Check the applicable benefit and figures with INPS or the relevant public employer.
