Boro were forced to take a late battering from the Brewers, but they hung on for a share of the spoils.
Little happened in the early knockings of the North Yorkshire derby.
There was a sniff from distance for Tadcaster through Josh Barrett and Chris Howarth, but neither troubled keeper Tommy Taylor.
At the other end Boro created little, until just before the 30th minute when they were so unlucky not to take the lead.
It looked as though all Michael Coulson had to do was to divert Max Wright's cross on target when he was picked out in the six-yard box, but somehow Michael Ingham managed to claw the ball away and Tadcaster could breathe again.
Few other memorable moments followed in what was a quiet first 45 minutes, whetting the appetite for much more when the new period got underway.
Sadly, little changed after the half-time oranges, with the teams continuing to find their range in the derby battle.
As the minutes ticked on towards the hour, Tadcaster began to press forward, though all they could summon was a effort from former Boro man Pete Davidson, which grazed the top of the Boro bar.
Steve Kittrick's men still contributed as an attacking force, but chances began to dry up further on the banks of the River Wharf.
In contrast, Tadcaster finished with a flourish, throwing everything at Boro in the final minutes of the game.
Keeper Taylor made a string of superb stops, the best being a point-blank palm that pushed away a far-post header from Howarth.
Bodies were continually put on the line in the dying embers, as Boro hung on to what could be a vital point in the promotion shake-up.
