The State Tax Assessor may extend the time for payment of the tax or any part of the tax for a reasonable period of time not to exceed one year from the date fixed for payment and may grant successive extensions. The aggregate of extensions with respect to any estate may not exceed 10 years, unless a longer period is called for by a payment arrangement elected pursuant to section 4069‑A . If an extension is granted, the assessor may require the taxpayer:

Bond.
To give a bond to the Treasurer of State in such amount as the assessor determines necessary; or
2.
Other security.
To deposit with the Treasurer of State bonds or other negotiable obligations of governmental entities with an aggregate value sufficient to adequately secure payment of the tax.
