IMT, stamp duty and the cash needed to buy a home
A practical guide to the money needed by deed day in Portugal: IMT, stamp duty, Casa Pronta, registration, bank costs and insurance.

Buying a home in Portugal requires more than a deposit. Taxes, deed costs, registrations, bank charges and insurance may all need to be ready before you receive the keys.
Key takeaways
- The bank may finance the home, but usually not every purchase cost.
- IMT and stamp duty should be planned before the deed.
- Casa Pronta, notary, registration, bank and insurance costs also matter.
The costs to budget for
Before making an offer, separate the property price from the cost of completing the purchase. A typical purchase may include:
- deposit paid under the CPCV;
- IMT transfer tax;
- stamp duty on the property purchase;
- deed, authenticated private document, Casa Pronta or notary costs;
- acquisition registration and, with a mortgage, mortgage registration;
- stamp duty on the mortgage;
- bank fees, valuation and paperwork costs;
- insurance required by the bank;
- lawyer, solicitor or tax adviser fees, if you use professional support.
The common mistake is calculating only the down payment. The better question is: how much cash must be available by deed day, even if the mortgage is approved?
IMT depends on the property and use
IMT is Portugal's municipal property transfer tax. For housing purchases, the amount can change depending on price, tax value, how the home will be used and the buyer's situation.
Do not rely on one generic rule. A permanent own home may be treated differently from a second home. Buyers aged 35 or under may have exemption or reduction in certain cases. Rural property, other urban property and non-resident situations also need careful checking.
Before calculating IMT
- Confirm whether the purchase is for permanent own home use.
- Compare the price with the property's tax value.
- Check whether reliefs apply, such as IMT Jovem.
- Refresh the calculation against official tables before signing.
- Keep margin if price or category may still change.
Stamp duty has more than one layer
For the purchase itself, the best-known stamp duty is the duty on acquisition. The commonly referenced rate for this part is 0.8% of the relevant transfer value.
If there is a mortgage, stamp duty may also apply to the financed amount. For loans with a term longer than five years, Banco de Portugal references 0.6% of the financed amount. Stamp duty may also apply to bank commissions.
| Cost | When it appears | Watch out |
|---|---|---|
| IMT | Before the deed. | Depends on category, value and possible exemptions. |
| Purchase stamp duty | On property acquisition. | Do not confuse it with mortgage stamp duty. |
| Mortgage stamp duty | When bank financing is used. | Depends on loan term and financed amount. |
| Stamp duty on commissions | On some bank commissions. | It should appear in the FINE and fee sheet. |
Deed, Casa Pronta and registration
The deed or authenticated document formalizes the purchase. Then the acquisition must be registered. If there is a mortgage, the mortgage must also be registered.
Casa Pronta can handle purchase, mortgage, registration and IMT/stamp-duty steps in one counter. The cost depends on the number of registration acts and properties. As an official reference, the service page lists 375 euros for one registration act on one property and 700 euros where there is more than one registration act, such as a financed purchase.
If you use another route, such as a notary, lawyer, solicitor or registry office, ask for the estimate in writing. The final cost can change with mortgages, cancellations, powers of attorney, extra documents or urgency.
Mortgage and bank costs
The monthly payment does not show every credit cost. Before choosing a bank, read the FINE and confirm:
- valuation fee;
- application, study or formalization fee, if any;
- stamp duty linked to the mortgage;
- insurance required by the bank;
- bundled products that change the spread;
- account, card or other service costs;
- proposal validity and reflection period.
A lower spread may not be worth it if insurance, fees or bundled products make the total cost higher. Compare the APRC, total amount payable and real conditions, not only the first monthly payment.

Next step
Before negotiating the CPCV, make a cash-to-completion list: down payment, deposit, IMT, stamp duty, deed, registration, bank, insurance and professional support. If the list is tight, adjust the price, timeline or financing before turning the purchase into a binding commitment.
