IRS Installment Agreement — Short-Term vs Long-Term Plans Compared

#installment agreement#IRS payment plan#short term plan#long term plan

The IRS offers two main installment agreement types: short-term (up to 180 days) and long-term (up to 72 months). The right choice depends on whether you can realistically pay within six months. Short-term plans have no setup fee and lower total interest. Long-term plans have lower monthly payments but cost significantly more over time.

Compare both plans for your balance with the IRS Payment Plan Calculator.

Short-Term Plan in Detail

Who qualifies: Anyone who owes $100,000 or less (including penalties and interest) and can pay within 180 days.

How it works: You agree to pay the full balance within 180 days. There's no formal monthly payment amount — you can pay in any schedule as long as the balance is zero by day 180.

Example: $12,000 BalanceAmount
Monthly payment (if paying evenly over 6 months)$2,000
Interest over 6 months (~4%)$480
FTP penalty (0.5%/month × 6)$360
Total cost$12,840

Advantage: No setup fee, lower total interest and penalties, no tax lien.


Long-Term Plan in Detail

Who qualifies (streamlined): Anyone who owes $50,000 or less and needs more than 180 days to pay.

How it works: The IRS calculates a minimum monthly payment based on your balance divided by the remaining collection statute (typically 72 months or the time remaining on the 10-year statute of limitations).

Example: $12,000 Balance, 60-Month PlanAmount
Monthly payment$200
Setup fee (online, direct debit)$22
Total interest over 5 years~$2,900
Total FTP penalties (0.25%/month × 60)~$1,800
Total cost$16,722

Compared to the short-term plan's $12,840, the long-term plan costs nearly $4,000 more for the same $12,000 debt. The difference is entirely from extended interest and penalties.


When to Choose Each Plan

Your SituationBest Choice
Can pay full balance within 6 monthsShort-term (saves money)
Need more than 6 monthsLong-term (lower monthly payments)
Balance over $50,000Short-term (if you can; long-term requires financial disclosure)
Want to avoid a tax lienShort-term (liens rare) or long-term with direct debit
Low income and strugglingLong-term with reduced setup fee

Direct Debit vs Manual Payments

For long-term plans, direct debit (automatic monthly withdrawal from your bank) has important advantages:

FeatureDirect DebitManual (check/online)
Setup fee$22$69
Risk of defaultLower (automated)Higher (easy to forget)
Lien avoidanceMore likelyLess certain
Penalty reduction0.25%/month0.25%/month

If you default on an installment agreement (miss payments), the IRS can revoke it and take enforced collection action. Direct debit eliminates the risk of accidental missed payments.
