What documents does DOF require to prove primary residence?
DOF accepts either a recent state or federal income tax return listing the property as your permanent home address, or a combination of two 'home-address' documents such as a New York State DMV ID and NYC voter registration. The surcharge applies to non-primary NYC residences valued above $1 million for condos and co-ops, with rates of 4% on market values from $1M-$3M, 5.25% from $3M-$5M, and 6.5% above $5M.
Conquest's analysis of DOF's July 2026 Supplemental Market Value Roll shows roughly 24,000 units citywide would owe the surcharge if they are non-primary residences. Most are primary residences and owe nothing. The exemption application deadline is October 6, 2026 for all owners who received DOF's 'You may be subject to...' notice.
Does a tax return alone prove primary residence?
Yes, if filed recently. DOF's final rules state that 'unless credible information indicates otherwise,' the department will treat a property as a primary residence if the owner listed it as a permanent home address on their most recently filed state or federal income tax return.
This carries the highest evidentiary weight because DOF can cross-check the filing against its tax data. Professional alerts uniformly treat tax returns as top-tier proof for the surcharge, which took effect July 1, 2026 and sunsets June 30, 2031.
What if I don't have a tax return showing the NYC address?
DOF accepts two or more documents showing the property as your home. The strongest combination is an unexpired New York State DMV driver's license, learner's permit, or non-driver ID listing the property address, plus NYC voter registration at the same address.
Consider a Manhattan condo owner whose 2025 tax return lists a Connecticut address but who moved to the city in early 2026. That owner would need the DMV ID plus voter registration combination to establish primary residence as of the January 5, 2026 taxable status date.
Do property tax exemptions help prove primary residence?
Yes. DOF may rely on New York School Tax Relief (STAR), veterans' exemptions, senior citizen exemptions, or NYC Enhanced Real Property Tax Credit as evidence that a property is treated as a primary residence for tax purposes.
These exemptions significantly corroborate primary residence because they require the same underlying residency determination. However, they supplement rather than replace the core documentation requirements.
What documents work for tenants claiming primary residence?
For properties used as the primary residence of tenants or subtenants, DOF accepts either a copy of the current lease plus one additional rental document, or a Tenant or Subtenant Affidavit plus two additional rental documents.
Additional rental documents include utility bills, proof of rent payment, or renter's insurance policies listing the property as the insured residence. The tenant exemption requires a 12-month arm's-length lease with a natural person.
How does DOF verify occupancy during the year?
DOF's final rules recognize 'proof of occupancy during the 12 months preceding the taxable status date' as supporting evidence when submitted alongside qualifying documents. This includes utility bills showing continuous usage at the property or bank statements documenting regular rent payments.
The key date is January 5, 2026 for the current tax year. Occupancy throughout the calendar year matters less than establishing primary residence status as of that specific taxable status date.
What happens if DOF rejects my primary residence claim?
Owners receive 30 days from a notice's transmission date to appeal DOF's determination. The appeal must include a certification that the property is used as a primary residence plus the documentary proof described in DOF's rules.
Surcharge is based on DOF market value (the 'Market Value' line on the Notice of Property Value), not assessed value. DOF's final rules state verbatim: 'Because the surcharge is based on market value, not assessed value.' First payments are due January 1, 2027, and regular property tax abatements do not offset the surcharge.
Frequently asked questions
Is my apartment subject to the NYC pied-à-terre tax if I live there part-time?
The surcharge applies to non-primary NYC residences valued above $1 million for condos and co-ops, with rates of 4% on market values from $1M-$3M, 5.25% from $3M-$5M, and 6.5% above $5M. If you can prove the property is your primary residence as of January 5, 2026, you would be exempt from the surcharge.
How much is the tax on a $2 million condo that's not my primary residence?
The surcharge rate is 4% on market values from $1M-$3M, so a $2 million condo would owe $80,000 annually. The surcharge is based on DOF market value, not assessed value, and first payments are due January 1, 2027.
Does filing my tax return with my NYC address prove primary residence for the pied-à-terre tax?
Yes, DOF will treat a property as a primary residence if you listed it as a permanent home address on your most recently filed state or federal income tax return, unless credible information indicates otherwise. This carries the highest evidentiary weight because DOF can cross-check the filing against its tax data.
