Unregistered Old House Tax Record and Purchase Risks

在雙北老舊聚落、老街商圈或中南部鄉村看屋時，常會看到一些總價只要市價 5 折至 6 折的超平價老透天或平房，仲介常熱情推銷：「這間雖然沒有建物所有權狀，但是有房屋稅籍證明！我們去稅捐處辦理契稅申報過戶就可以買賣，買到賺到！」許多首購族以為撿到大便宜，簽約付款後才驚覺：銀行完全拒絕辦理房屋貸款、房屋隨時面臨工務局即報即拆、甚至土地所有權人跳出來要求拆屋還地！ When touring older neighborhoods in Taipei and New Taipei, historic districts, or rural settlements across Taiwan, buyers often encounter bargain townhouses priced at 50% to 60% of market value (5 to 6 fold discount). Real estate agents often pitch: Although this property lacks a building title deed, it has a house tax certificate; filing deed tax at the revenue office transfers ownership easily. Many buyers assume they found a bargain, only to discover banks reject mortgage applications, public works bureaus threaten demolition, or land owners demand building removal and land return. Unregistered properties (commonly called tax record houses) possess unique legal backgrounds. Is buying them legal? What fatal pitfalls exist? This guide breaks down legal protections.

1. What Is an Unregistered House? Does a Tax Certificate Prove Legal Ownership?

Distinguishing land registry legal concepts reveals the gulf between tax records and true ownership rights:

2. 2 Historical Origins of Unregistered Houses: Legal Historic Homes vs Illegal Additions

Unregistered houses are not all illegal structures; their construction era must be verified:

1. Origin A: Historic Structures Built Before 1958 (Legal Old Buildings):
   • Before the Building Act and urban planning regulations took effect in 1958, building permits and use permits were not legally required.
   • Older generations established tax records to pay annual house taxes without applying for initial property registration at the Land Office.
   • These historic structures are legally recognized. By presenting utility installation records, original household registrations, or aerial photography, eligible owners can apply for use permits and retroactively obtain title deeds.
2. Origin B: Unauthorized Structures Built After Regulations (Illegal Additions):
   • Structures built without construction permits on leased or occupied land after building control acts were enacted.
   • Construction management agencies can demolish them under illegal building regulations. Paying house taxes does not make structures legal, and demolition occurs without compensation.

3. 4 Fatal Pitfalls When Purchasing Unregistered Houses

Buyers evaluating low-priced unregistered homes must conduct strict due diligence with licensed scriveners:

• Pitfall 1: Purchasing De Facto Disposal Rights Without Land Ownership:
  • The underlying land belongs to someone else (National Property Administration, ancestral trusts, or private owners), while the seller merely leases or squats on the land.
  • Land owners can file civil lawsuits under Civil Code Article 767 demanding building demolition, land return, and 5 years of retroactive unjust enrichment rental compensation.
• Pitfall 2: Requiring 100% Cash Due to Absolute Bank Loan Denial:
  • Because no building transcript exists, banks cannot register first-priority mortgages. Unless the underlying land carries substantial value, the entire purchase price must be paid in full cash.
• Pitfall 3: Land Value Increment Tax and Consolidated Real Estate Tax Disputes:
  • While title transfers do not go through land registries, buyers must declare deed taxes at the tax office to transfer the taxpayer of record, and simultaneous land transfers trigger heavy land value increment and income taxes.
• Pitfall 4: Zero Compensation Following Natural Disasters or Public Condemnation:
  • If old structures collapse from fire or earthquake, statutes forbid rebuilding unrecorded structures, extinguishing your disposal rights; road widening condemnations compensate only legal structures with meager relief for illegal units.

4. 4 Safety SOP Steps When Purchasing Unregistered Houses

If purchasing properties with urban renewal potential, enforce these transactional safeguards:

1. Insist on Full Land Ownership Transfer (1/1 Land Share):
   • Never buy buildings without land. Ensure the seller holds the land title deed (1/1 full ownership). Once the land transfers to your name, you control future rebuilding.
2. Review Building Survey Maps and Plot Overlay Drawings at Land Registry:
   • Confirm whether the land is encumbered by adjacent permits and check whether the structure encroaches on neighbor boundary lines.
3. Notarize De Facto Disposal Rights Transfer Agreements:
   • Have a licensed scrivener draft agreements explicitly transferring all possession and de facto disposal rights to the buyer, notarized before civil notaries to eliminate inheritance disputes.
4. Transfer Utilities and Household Address Registrations:
   • On closing day, visit Taipower, Taiwan Water, and household registration offices to transfer meter accounts and doorplate records into the buyer's name to establish unbroken legal usage chains.

5. Unregistered House FAQ

Q1: Can owners of unregistered houses apply to the Land Office to retroactively obtain title deeds?

Under specific conditions, yes. If the structure existed prior to local urban planning or building control acts (built between 1958 and 1971 / 民國 47-60 年), owners can present pre-1958 tax certificates, initial utility bills, household records, or aerial photos to obtain a Legal Building Certificate, followed by initial property registration at the Land Office to secure deeds.

Q2: Can unregistered houses be rented out? Can tenants apply for 300 billion (300 億) rental subsidies?

Yes, and tenants can legally claim 300 billion (300 億) rental subsidies. National Land Management Agency rules allow tenants in unregistered buildings to submit leases, tax certificates, or utility bills proving residence to receive 2,000 to 8,000 TWD monthly subsidies while landlords receive tax incentives.

Q3: Must buyers pay deed taxes and land value increment taxes when buying unregistered homes?

Full taxes must be paid. Although building transfers skip land offices, changing the taxpayer of record at local tax bureaus requires paying Deed Tax (calculated at 6% of assessed house present value), and accompanying land transfers trigger land value increment taxes.

Q4: Can unregistered old houses participate in urban renewal or dangerous building reconstruction?

Yes, provided they obtain official recognition as legal buildings. Under urban renewal statutes, participating structures receiving floor area bonuses must be certified legal buildings. Securing municipal validation allows original building volume and land shares to participate 100% in renewal allocations.
