730 tax return deadline 2026: 30 September is the last day to file

30 September: what really changes on that date

Every year, towards the end of June, the same sentences start going round at our counter in the Padova area: «there is plenty of time», «I will do it in September». Last year it was Marco's turn — a cook who lives in via Padova and turned up on 3 October with his folder in his hand and the face of someone who has got his sums wrong. That day the 730 form could no longer be used.

There is only one date to mark: Wednesday 30 September 2026. By that day you file the 730 on your 2025 income, in the pre-filled or in the ordinary version, even if you have no employer acting as withholding agent. There are no extensions: anyone who misses the deadline has to move to other forms.

Who has to file the 730 and who can relax

Who needs the 730

It is for employees and pensioners who have expenses to claim as deductions: visits and medicines, the mortgage instalment, rent, school fees, current account interest. Even people whose tax is already withheld from their payslip often have an interest in filing: the return is exactly what recovers what was withheld in excess.

Who does NOT need it

If in 2025 you had only one salary or one pension, with no expense to deduct, as a rule you do not have to file anything: the balancing has already been done by whoever pays your salary. If instead you have a VAT number, receive rent, or have put together more than one job, the right form is Redditi PF and the deadline is a different one, 2 November 2026. Do you suspect this is your case? Call us: the first consultation at the office is free.

The folder to bring to your appointment

There is nothing to prepare in advance: an envelope with the right documents is enough, and we fill it in together at the counter.

• a valid identity document and your tax code, yours and your spouse's if you file together
• the Certificazione Unica 2026: the sheet with your 2025 income, given to you by your employer or by INPS
• itemised receipts and invoices for the medical expenses you paid in 2025
• the mortgage statement, if you are paying an instalment on your main home
• the tenancy agreement and the rent receipts, if you live in rented housing
• your ISEE certificate, when you need it for nursery school or other benefits
• the itemised bank transfers, if in 2025 you had work done with a home bonus

A good part of this data is already inside the pre-filled 730 prepared by the Revenue Agency. What makes the difference is the check: a 200 euro receipt forgotten at the bottom of a drawer is a deduction that never comes back. That is why the half hour of checking at the office is always worth it.

How the appointment at our counter works

At the office the job is closed in about thirty minutes, split into three steps.

1. Choose the day

Book however you prefer: a phone call to +39 02 0000 0000, a WhatsApp message to +39 329 000 0000, or a visit to Via privata Atene 6, in the Padova district a stone's throw from via Padova. We are open Monday to Friday, from 9:30 to 12:30 and from 15:00 to 19:00, and we receive by appointment only, so that nobody has to wait standing up. The busiest days are always the last ones of September: those who call earlier find a slot whenever they like.

2. We fill it in and show you the result

You bring the folder, an operator enters the data and shows you how the return comes out before sending it. If the 730 closes in credit you find out straight away how much comes back to you; if it closes in debit you know how much and when to pay. You get the quote before we start: no surprises at the end of the job.

3. Sending and receipt

We transmit the form electronically to the Revenue Agency and leave you the receipt of filing. Keep it with your other tax documents: it is the proof that you are in order.

Back to Marco, the cook from via Padova: after that slip he booked in June of the following year and was sorted in half an hour. «I did not imagine it would be so quick», he told us as he walked out of the door.

Past the deadline: the ladder of what happens

Not filing the 730 does not make you disappear from the tax office: the route and the bill change. Here is how things stand, according to the official rules:

• Up to 30 September 2026: you file the 730 normally. Zero penalties, zero extra costs.
• From 1 October to 2 November 2026: the 730 can no longer be used, but Modello Redditi PF replaces it with no penalty, because the ordinary deadline falls on 2 November (31 October is a Saturday).
• After 2 November 2026: the 90 days of the late return start. The document is still valid, but a fixed penalty of 250 euro arrives, which with the ravvedimento operoso drops to 25 euro if you have no taxes to pay.
• Beyond those 90 days (early February 2027): the return is considered omitted. The penalty rises to 120% of the taxes due, with a minimum of 250 euro; if there is nothing to pay, a fine of between 250 and 1.000 euro still remains.

There is also an effect that is rarely noticed and weighs a lot: without a regular return the ISEE is not released, and without the ISEE the single allowance, the reduced university fees and several bonuses stop. A tax delay, within a few months, becomes a problem that touches the whole family.

Made a mistake after sending? It can be corrected

If you realise you have forgotten a receipt, or that the name of a dependent child is written wrongly, it is not over: the 730 integrativo exists, to be filed by 26 October 2026. When the correction is bigger you move to Modello Redditi correttivo, by 2 November. Just bring us the filing receipt: we take care of the rest. If the doubt has only come to you now, this is the right moment to fix an appointment at the office.
