Taxes on the typical single-family home in the cash-strapped Big Apple are going up next year by 8.8 percent, from $3,233 to $3,519.

But if the City Council hadn’t acted to protect those homeowners, the increase would have been 14.3 percent, to $3,695, officials said yesterday.

The average co-op faces a 10.3 percent hike, from $4,467 to $4,930.

The Finance Department will be sending out bills soon to reflect higher property assessments during the boom years that are still being phased in.
