Our experience with IAS Ticino

What we learned filling in the forms, from the office's own information and documents, and with our customers. Always with date and source.

Information from the office
The tax certificate comes from the office
Each year the IAS issues your employee a certificate confirming the source tax paid, directly to her. That is the document she attaches to her tax return.

Form tested
Do not leave point 6 blank
The «modulo 111» warns: if point 6 is left blank, the office enrols you in the simplified procedure without Plus, and you must take out accident insurance separately. If you name no insurer at all, the office reports you to the substitute accident fund (Cassa suppletiva LAINF), which assigns you an insurer.

Do I need my accident and pension policies before sending «modulo 111»?

No. At points 6 and 7 the form offers «affiliazione in corso»: you send the copy of the contract after registration. Point 7 also lists the grounds for exemption from occupational pension (BVG), the first being a wage below the BVG entry threshold. Accident insurance is still compulsory from the first working day.

When is source tax deducted in Ticino?

Every month, from your employee's wage: that is what «modulo 111» states. The office, on the other hand, settles and collects the social contributions and the source tax only once a year.

Can the office's mail go to another address, for example a trustee?

Yes, but if you give a different «Indirizzo di recapito» at point 2 of «modulo 111», you must enclose a power of attorney. If the mail should come to your home, choose «identico».
