Accounting management for professionals: complete guide 2026
Are you a lawyer, architect, consultant, doctor, or designer? Managing your accounts has specific characteristics that distinguish it from a commercial company’s bookkeeping. This guide explains what you need to know.
The tax specifics of the self-employed professional
Self-employed professionals in Italy produce income from self-employment (art. 53 and 54 TUIR), subject to different rules than business income. The main differences:
- Income is determined on a cash basis (receipts minus payments), not an accrual basis
- Fees are subject to a 20% withholding tax (recovered in the annual return) except under the flat-rate regime
- Mandatory registration with the Professional Fund or INPS Separate Management scheme
- Obligation to apply the professional fund surcharge of 2% or 4% depending on the fund, and option to apply a 4% INPS surcharge on invoices to clients
Choosing the right tax regime
Flat-rate regime (if revenue ≤ €85,000)
Advantages:
- Fixed taxation at 15% (5% for the first 5 years if requirements are met)
- No VAT to charge or pay
- No withholding tax applied by clients
- Minimal bookkeeping: only an issued invoices register and fees register (corrispettivi)
When it is NOT advantageous:
- If you have many deductible expenses (the flat-rate deduction may be lower than actual costs)
- If you expect to exceed €85,000 in revenue
- If you also have employment income > €30,000/year
Standard regime (revenue > €85,000 or voluntary choice)
In the standard regime, the professional:
- Charges VAT at 22% (or the specific rate for the service)
- Deducts all documented and relevant expenses
- Pays IRPEF at progressive rates (23%–43%)
- Pays municipal and regional surtax
Deductions for professionals in the standard regime
The following expenses are 100% deductible if documented and relevant to the activity:
- Office lease (or the business-use portion of a home)
- Office utilities (electricity, gas, internet, phone)
- Professional software and hardware
- Training and professional development
- Books, journals and professional subscriptions
- Professional liability insurance
- Contributions to professional orders and associations
- Fees to collaborators and employees
- Representation expenses (within legal limits)
Partially deductible:
- Vehicle: 20% for mixed use, 100% if exclusively for professional use
- Mobile phone: 80%
- Meals and travel: subject to specific limits
Key tax deadlines for professionals
| Deadline | Obligation |
|---|---|
| 16 March | Annual VAT payment (if on quarterly basis) |
| 30 April | Annual VAT return |
| 30 April | Electronic submission of withholding certificates (CU) to collaborators |
| 30 June | IRPEF balance + 1st advance (or deferred to July with surcharge) |
| 31 October | UNICO return (individuals) |
| 30 November | 2nd IRPEF advance payment |
Social security and INPS contributions
INPS Separate Management (for those without a Professional Fund):
- 2026 rate: 26.07% of net income (reduced to 24% for pensioners or those with other pension coverage)
- The 4% surcharge is optional but reduces the net social security cost
Professional Funds (lawyers, doctors, architects, engineers, etc.):
- Variable rate per fund (typically between 10% and 15%)
- Mandatory for registered members
- Includes subjective contributions + supplementary contributions + solidarity contributions
How to structure document management
A good document management system for a professional includes:
- Updated invoice register (mandatory for the standard regime)
- Systematic collection of purchase invoices
- Monthly bank statements
- Receipts for all professional expenses
With mandatory electronic invoicing, many aspects are automated. Your accountant can configure the system so that you only receive the data needed for your day-to-day activity.
